halves)的永久模是被 牢固地夾持在一個操作處理單元裏，該操作處理單元又被 稱爲操控器。這個操作處理單元同樣地也是被固定地連接 到一個輸送器裝置上，該輸送器裝置將操控器連同該永久 模一起從一個工作站移動到下一個工作站。該操控器包含 有一個開啓和關閉機構，藉由這個開啓/關閉機構，便可 以依照各個工作站裏預定要進行的工作步驟來打開和閉合 該永久模，譬如，***型芯、鑄造、移出壓鑄件、淸理、 施加淸洗膜等。在這個案例裏，該永久模是始終在閉合的 狀態下被搬運到各個工作站。由於該永久模本身的龐大重 量’該開啓/關閉機構需要有用來保持該永久模之模半 (mold halves)的堅固元件以及對應的傳動部件。再者，該 操控器必須施加相當大的作用力以便抵抗壓鑄站裏兩個永 久模模半內部上升的金屬液體壓力並且將兩個模半保持在 一起，以免在壓鑄件表面上形成稜邊。因而，爲了要施加 所需要的閉合作用力並且讓兩個永久模模半作相對的移動 ’該操控器也需具有一個大的自身重量。這個質量需由輸 _ 4 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） «ϋ ϋ— Β—9 ί n n —ϋ n vn n 1· fn · n n i i mmm§ flu an-· D ·>1 n It I— n 1· I _ (請先閱讀背面之注意事項再填寫本頁) 537939 A7

質量以外’當更換壓鑄模或永久模的時候缺乏適當的適應 彈性也代表傳統裝置的一項缺點。永久模必須自操控器上 取下’也问時在組裝上造成相應的費用支出。 因而’本發明之目的是要提供一種沒有上述傳統裝置 之缺點的低壓力壓鑄設備，在該低壓力壓鑄設備裏，該操 控器的機械設計結構是簡單的，並且在個別的工作站之間 的移動是快速而且減少能源的消耗。 本發明藉由一種具有如申請專利範圍第1項和第12 項所述之特徵的低壓力壓鑄設備、一種操作此類低壓力壓 鑄設備且具有申請專利範圍第1 6項所述之特徵的方法、 以及具有申請專利範圍第1 7項所述之特徵的永久模以達 成上述之目的。由相關的申請專利範圍、說明和隨附之圖 式使得本發明的有利之改進將變得明顯可知。 在一低壓力壓鑄設備裏，其具有至少一個壓鑄工作站 和至少一個其它工作站，較佳爲一個***型芯之工作站、

Description of the invention (1) < Background of the invention > The present invention relates to a low-pressure die-casting device as described in items 1 and 12 of the scope of patent application, The operation method described in item 6 and a permanent mold as described in item 17 of the scope of patent application. Low-pressure die-casting equipment has been publicly disclosed in documents such as C Η 6 903 0 6 and E P — AO 8 2 4 9 8 3. Among the disclosed equipment, the permanent mold including two permanent mold halves is firmly held in an operation processing unit, which is also called a manipulator. This operation processing unit is likewise fixedly connected to a conveyor device which moves the manipulator along with the permanent mold from one workstation to the next. The manipulator includes an opening and closing mechanism. With this opening / closing mechanism, the permanent mold can be opened and closed according to the predetermined work steps in various workstations, such as inserting a core, casting, and removing a die casting. , Cleaning, application of cleaning film, etc. In this case, the permanent mold is always transported to the workstations in a closed state. Due to the huge weight of the permanent mold itself, the opening / closing mechanism needs a solid element for holding the mold halves of the permanent mold and a corresponding transmission component. Furthermore, the manipulator must exert a considerable force to resist the rising liquid metal pressure inside the two permanent mold halves in the die casting station and keep the two mold halves together to avoid forming edges on the surface of the die casting. Therefore, in order to apply the required closing force and move the two permanent mold halves relative to each other, the manipulator also needs to have a large own weight. This quality needs to be _ 4 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) · D · > 1 n It I— n 1 · I _ (Please read the precautions on the back before filling this page) 537939 A7 V. Description of the invention (>) Incurring corresponding costs. The manipulator has a complicated mechanical design and is therefore also expensive to manufacture and maintain. Each time the permanent mold is opened and closed in a separate workstation requires a long operating time. As a result, the entire operating cycle is increased, and the permanent mold may be cooled to a minimum requirement under certain circumstances. Below the temperature, an additional heating step is required. In addition to the high inertial mass of the entire system due to these large masses, the lack of proper adaptability when changing die casting or permanent molds also represents a disadvantage of conventional devices. The permanent mold must be removed from the manipulator, and the corresponding cost will be incurred during assembly. Therefore, the object of the present invention is to provide a low-pressure die-casting device that does not have the disadvantages of the above-mentioned conventional device. In this low-pressure die-casting device, the mechanical design structure of the manipulator is simple, and the movement between the individual workstations is simple. It is fast and reduces energy consumption. The invention is based on a low-pressure die-casting device having the features described in claims 1 and 12, and a method of operating such a low-pressure die-casting device and having the features described in claim 16 , And a permanent mold having the features described in item 17 of the scope of patent application to achieve the above purpose. Advantageous improvements of the invention will become apparent from the relevant patent application scope, description, and accompanying drawings. In a low pressure die-casting equipment, it has at least one die-casting station and at least one other station, preferably a core inserting station, a take-out station, a sandblasting station, and a dip and / or spray station.

Description of the invention (j) At least one has a younger brother—there is a first kind of design_ First, the unit is the first picking process suitable for design. The early operation β operation processing unit is suitable for transporting a closed forever = 'Each operation is handled by carrying an open ice for a long time, which is also the annual unit. It is designed according to the purpose it wants to accomplish. A The first-designed operation processing unit is able to close the function for a long time and the function of handling the closed permanent mold is optimized. The permanent mold is preferably housed in a receiving shaft, which—preferably in a substantially precise fit—encloses the closed permanent from the direction of at least two sides. mold. The two permanent mold halves are pushed together towards each other, and the permanent mold is fixed inside the shaft by a closing mechanism, and the closing mechanism includes a closing element such as at least one closing piston . This need for mechanical costs is inexpensive because the closing piston only has to be clamped in a permanent mold 'that houses the shaft and only a short stroke is sufficient. No other mechanism is required to open the permanent mold using the first operation processing unit. During casting, the permanent mold stays inside the first processing unit. The second design of the operation processing unit optimizes the transport of open permanent molds. Since the permanent molds moving between the workstations are in the open state, and the processing operations to be performed by these workstations are also performed with the permanent molds in the open state, time is saved. The second operation processing unit has two holding elements, each of which is used to hold a mold half of a permanent mold. The held permanent mold halves are separated from each other at a distance, and are placed in directions parallel to each other.

Description of the invention (today) The opened permanent mold is transported to each workstation for another processing operation depending on the method steps to be performed ——For example, it is sent to the core insertion station; or it is kept attached to the operation and processing unit ~ ^ For example, during the operation of applying graphite to the permanent mold. Thanks to this design that optimizes the function, the operating unit eliminates the need for moving parts and sturdy, heavy components. Whenever needed, the opening and closing actions are performed directly by a fixed opening and / or closing device on the workstation. In a second variation of the present invention, the casting station is assigned a clamping unit to accommodate a permanent mold with a coupling element. During the casting operation, the clamping unit halves two permanent molds. Hold together. Furthermore, 'a grasping and conveying system is provided', the grasping / conveying system is provided with at least one operation processing unit 'and is used to accommodate being delivered to the casting station by engaging with the coupling element Or the permanent mold picked up by the clamping unit on the casting station, and the permanent mold is delivered between the next station and the casting station or between the station and another station. Therefore, the permanent mold is not fixedly held in a manipulator, but is moved between individual workstations or in a workstation. It is also possible to use the operation processing unit of the first design or the second design according to the first modification of the present invention. The required closing force is applied to the casting station by the fixed clamping unit. The clamping unit houses the permanent mold, and preferably clamps the permanent mold in a tight fit. Because the permanent mold has a single external dimension unrelated to the casting, for example, it has at least one predetermined thickness, the clamping unit is suitable for 7 paper sizes in accordance with Chinese National Standard (CNS) A4 (210 X 297). ) ------------, -------- Order --------- Line · (Please read the notes on the back before filling this page) A7 537939 5 2. Description of the invention (() can be made essentially from: a single piece of material, and the permanent mold is inserted into the single-piece piece, and, if necessary, is clamped with a relatively small force Hold it in. The clamping unit does not have to be moved. The permanent mold is inserted into the clamping unit, and it is taken out of the clamping unit again by operating the processing unit. During the actual conveying operation The two permanent mold halves can be held together without applying a high degree of force. Therefore, the end-to-end processing unit can, for example, have a very light weight gripping and transporting unit, which The unit simply squeezes the two permanent mold halves against each other in order to hold them Just put it together. The operation processing unit used can also be, for example, a robot. In short, the operation processing unit does not have to be as strong as the traditional manipulator described previously because the mass to be moved is light Therefore, the design becomes simpler and cheaper. Because the permanent mold is not fixedly connected to an operation processing unit shared by all workstations, the device of the present invention can have a completely modular structure. Because of the device The application flexibility is increased, so if necessary, more workstations can be introduced or modified. It is also possible to combine the two variations of the present invention 'for example' using the first design and the second design of the operation processing unit To transport the permanent mold in the closed or open state, and send it to a stationary clamping unit on the foundry station. In this way, the first set of ten processing units can be made even Lighter weight. The device of the present invention preferably uses permanent molds with standardized external shapes. Such permanent molds, such as , Has a body, the body contains 8 (please read the precautions on the back before filling this page) # order --------- line paper size applicable to China National Standard (CNS) A4 specifications (210 X 297 male t) 537939 A7 ------------- B7_ _______ V. Description of the invention (b) The actual casting mold and connection elements, these connection elements are in the form of: Side flanges or slabs together. These coupling elements are arranged so that the spatial dimension of the permanent mold is independent of the size of the body in at least one spatial direction. This enables it to utilize a plurality of different casting molds and visual These casting molds need to be replaced without additional design costs. The clamping elements or clamping devices of the operating processing unit-the clamping unit and other opening and closing devices can be provided with a unified gripping system. The gripping system enables the operating unit to manipulate the permanent mold in the desired manner, such as squeezing it together during casting, pulling it apart and pivoting it to cool, and so on. Therefore, the receiving shaft of the first operation processing unit preferably has a depth that fits the distance between the permanent mold half coupling elements in the closed state. In each case, these operation and processing units are connected to a drive unit and can be moved independently of each other. The operation processing unit can preferably move along a linear guide track and adjust their height. In an advantageous refinement of the invention, the permanent molds have a code which represents the type of the permanent mold, for example, the shape of the casting. This code is read by an appropriate reader unit located on each workstation, and is transmitted to a system control unit via a corresponding signal. The system control unit can be a central centralized control unit or Local control unit. The system control unit provides the data needed for the workstation to control the work process. By way of an example, a predetermined pressure change curve is set in the casting station, that is, a pressure curve graph that changes with time, which is set at the casting station with 9 (Please read the precautions on the back before (Fill in this page) Order --------- Line-This paper size is applicable to China National Standard (CNS) A4 (210 x 297 Gongchu) 537939 A? ^ __ B7 _ 5. Description of the invention () Piece shape. As another example, a graphite coating station is cooled for a predetermined period of time. As another example, one of the functions of the Jiejie casting mold at the decontamination station is to move the decontamination nozzle over the open permanent mold. The coding is preferably mechanical, for example, the arrangement of some short pins, but it can also be generated by other methods, such as using a bar code or a data carrier. Sturdy mechanical coding enables multiple sentences to be read out even under slightly dirty working conditions. This unclean environment is very common during casting. A better way for each workstation is to assign a local control unit to control local work steps. Relevant process data is input to the central control unit and transmitted to the local control unit according to the requirements of the local control unit.

Description of the invention (丨 〇) The surface is, for example, engaged with a groove 16 provided in the center of the flat plate 5. The lateral coupling element 4 is designed such that the relative positions of the coupling points for operating the processing unit 1, 10, or other holding devices in the closed state are always the same regardless of the size and shape of the body 9. . The body 9 can be, for example, an elongated body (compared to the body 9 shown in Figs. 1a and 1b), or it can have a changed depth (not shown in the figure). In the latter case, the The webs 3 and 4 should be lengthened accordingly. Figures 1c to 1e show a slightly modified permanent die 3.

Description of Invention (Π) The operation processing unit can move along the horizontal and vertical directions of a guide rail 18. As a result, the frame 2 is placed on a closed permanent mold 3 due to the movement in the vertical direction. At this time, the permanent mold 3 is tied in a standing position, so that the permanent mold 3 is received on the receiving shaft. 3 5 miles with a slight fit clearance. The permanent mold 3 is fixed by a closed cylinder 7 which engages the hollowed-out portion 8 in the lateral coupling element 4. The stroke of the closing cylinder 7 required for this fixing operation is very small 'and is only a few millimeters (approximately 10 to 20 mm). The first operation processing unit 1 has no other moving elements, and thus it can be manufactured with a low construction cost. The closing device 6 holds the closed permanent mold 3 staying inside the first operation processing unit 1, and holds it during casting. The second operation processing unit 10 shown in FIGS. 3 a and 3 b is suitable for delivering the opened permanent mold, and the two permanent mold halves 3 a, 3 b of the permanent mold are at a distance from each other at this time, and Aligned parallel to each other. The second operation processing unit 10 also includes a U-shaped frame 1 1. The distance between the side walls 1 1 a and 1 1 b of the U-shaped frame 11 is larger than the frame 2 of the first operation processing unit 1. Each side wall 1 1 a, 1 lb contains a holding device 12. In this case, the holding device 12 includes a holding element 13 and a holding hydraulic cylinder 14. The holding element 1 3 is matched with a lateral coupling element. The short pin 15 of 4 acts intersectingly, and the holding cylinder 1 4 acts in cooperation with the hollowed-out part 8. The two permanent mold halves 3a and 3b are held and fixed inside the second operation processing unit 10 by the holding device 12. As the second operation processing unit 1 〇 is placed from above to stand upright 14 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) " (Please read the precautions on the back before filling this page) --- 11 --- Order ---------. 537939 a7 B7 --- A '----- V. Description of the invention (/ ^) and it is on the open permanent mold 3, so the permanent The mold is housed inside, and then the holding cylinder 14 is removed. Other gripping mechanisms and closed hydraulic cylinders can also be used. As in the first operation processing unit 1, this case also has no moving parts except for closing the hydraulic cylinder. Fig. 4 illustrates a preferred structure of a linear arrangement of a low-pressure die-casting quilt of the present invention. One casting station 19 and the other stations are arranged along a straight line, preferably arranged at regular intervals. The other workstations referred to in this case are a core insertion workstation 20, a take-out workstation 2 1, a permanent mold replacement workstation 2 2 ′-a washing station 2 3, and a coated graphite workstation 24. There is a waiting position 2 2 ′ between the casting station 19 and the core insertion station 20: If the permanent mold is not to be replaced at that time, the area above the permanent mold replacement station 2 2 can also be used as a waiting position. The left part of Figure 4 illustrates a side view of the casting station 19 rotated 90 degrees. The casting equipment has a first operation processing unit 1 and two second operation processing units 10 and 10 ′, and these operation processing units are respectively connected to a driving device 17 which drives the first operation processing The unit 1 and the second operation processing unit 10, 10 'cause them to move along a linear guide rail 18, and, in addition, allow the height of these operation processing units to be adjusted. These operation processing units 1, 10, 10 'can all be moved independently without affecting each other. Their actions are controlled by a control device (not shown). Since the permanent mold is not fixedly connected to a specific operation processing unit, three operation processing units can also be used in this linear arrangement. Compared with traditional devices, this will obviously 15 --------------------- Order --------- (Please read the precautions on the back before (Fill in this page) The paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) A7 537939 5. Description of the invention (!) Increasing the working cycle time of the device. An example of the operation of the permanent mold is illustrated in Figs. 1a and 1b. According to this example, the first operation processing unit 1 receives a closed permanent mold at the core insertion station, and moves it to the casting station 19, and then to the removal station 21. When the closed permanent mold is transferred to the take-out station 21, it is opened, after which the casting is taken out. During this time, the first operation processing unit has been moved back to the core insertion station to facilitate picking up a new permanent mold. The vacated permanent mold is picked up by the second operation processing unit 10 at the take-out station 21 and, in the opened state, is transported to the decontamination station 23 and transferred to a further station thereafter. After this transfer operation, the second operation processing unit 10 moves to the waiting position 2 2 '. Finally, the permanent mold that has been washed is picked up by another second operation processing unit 10 at the washing station 2 3, and is transferred to the coated graphite station 2 4 where the coated graphite station 2 At four places, during the graphite coating operation, the permanent mold stays on this second operation processing unit 10 '. The permanent mold is then transferred to the core insertion station 20, where the work cycle begins again. During this time, the actions performed by the other two operation processing units are also illustrated in Figure 11a. As a whole, it is capable of operating three permanent molds simultaneously, and can achieve a cycle time of the device in the range of 40 to 60 seconds. Because each permanent mold returns to the casting station 19 after a multiple of the working cycle time, no additional heating steps are required to keep the permanent mold at the desired temperature. The temperature of the permanent mold is measured and maintained by rinsing or spraying time. _ 16__ This paper size is applicable to China National Standard (CNS) A4 (21〇χ 297 mm) -------- ------------ Order --------- line (please read the notes on the back before filling this page) A7 537939 V. Description of Invention (I Today) . 5 to 10 are diagrams illustrating the structure of individual workstations. In the following technical notes, only the differences from traditional workstations are described. The structure of the casting station 19 shown in Fig. 5 is provided with an induction furnace which is the same as the conventional technique. The first operation processing unit 1 is used to place the permanent mold on the lifter 25 of the induction furnace. At the same time, the first operation processing unit 1 also applies the closing force required to close the permanent mold halves 3a, 3b. The core insertion station 20 illustrated in Figs. 6a to 6b includes a carrier 27, which can be moved across the guide rail 18 (see Fig. 4), and An opening and closing device 26 that is pivotable about a horizontal axis is connected to the carrier 27. In its lying state (left part of Fig. 6a), the opening and closing device can accommodate a permanent mold 3, and the permanent mold 3 is in an open state at this time. The opening and closing device 2 6 grasps and holds the lateral coupling element 4 of the permanent mold. This is illustrated diagrammatically in Figs. 6c to 6d: the permanent mold 3 is placed from above on the holding hydraulic cylinder 14 'which engages in the air-controlling portion 8 of the lower plate 5. Then, the closing hydraulic cylinder 7 'is moved into the lateral hollowed-out portion 8 of the plate 5, thereby clamping the latter. Since the opening / closing device 26 is pivoted by a 90 degree angle (see the right part of Fig. 6a), the permanent mold halves 3a, 3b are moved into a horizontal position, so that the sand mold core can be used at Insert manually. The permanent mold 3 is finally closed, and the opening and closing device is pivoted back to the lying position. The first operation processing unit 1 can pick up the closed permanent mold 3 in this state.
