Description
本創作係關於一種具溫控系統的中空成型機，尤指一種透過溫控系統控制夾模裝置溫度，進一步達到將模具之作業溫度控制在適當範圍的中空成型機。
The present invention relates to a hollow molding machine with a temperature control system, in particular to a hollow molding machine that controls the temperature of the clamping device through a temperature control system to further control the working temperature of the mold to an appropriate range.
市售有一種中空成型機，其主要是將顆粒狀的塑料加熱成熔融狀後，再使熔融狀之塑料大致形成中空管狀的胚料，於胚料外罩覆模具，並且在胚料內充氣，造成胚料受到氣體壓力抵壓而朝向模具之模穴內壁變型，待胚料冷卻後就能獲的與模具之模穴相同形狀的製品。There is a hollow molding machine commercially available, which mainly heats the granular plastic into a molten shape, and then causes the molten plastic to form a hollow tubular blank substantially, covering the mold with the outer cover of the blank, and inflating the raw material. The billet is deformed by the gas pressure and deformed toward the inner wall of the mold cavity, and the article having the same shape as the mold cavity of the mold can be obtained after the billet is cooled.
所述的中空成型機無論是欲將何種塑料加工成製品，模具的作業溫度都會影響製品的品質與製成的良率，以顆粒狀的聚乳酸塑料為例，其較佳要使模具的溫度保持在80。 C~130。 C之間，如此以聚乳酸塑料製成的製品才能具有良好的物理性質以及能夠有較高的製程良率。然而一般中空成型機用來提供模具結合的模座沒有能夠調整溫度的設計，因而在一開始作業時，模具的溫度低於80。 C，造成製品的品質不佳，而隨著作業時間拉長，模具吸收熔融狀之聚乳酸的熱量而升溫，造成模具的溫度可能介於80。 C~130。 C，但作業時間繼續拉長後，模具的溫度可能就會升高至超過130。 C，如此將造成模具的冷卻效果不佳，因而製品可能在尚未完全定型的狀態下脫模，造成最終的製品將可能會有變形量過大的問題。The hollow molding machine is suitable for processing the plastic into a product, and the working temperature of the mold affects the quality of the product and the yield of the product. For example, the granular polylactic acid plastic is preferably used for the mold. The temperature is maintained at 80 . C~130 . Between C, such a product made of polylactic acid plastic can have good physical properties and can have a high process yield. However, in general, a hollow molding machine is used to provide a mold-bonded mold base which has no design capable of adjusting the temperature, so that the temperature of the mold is lower than 80 at the beginning of the operation . C, resulting in poor quality of the product, and as the writing time is extended, the mold absorbs the heat of the molten polylactic acid and heats up, causing the mold temperature to be between 80 . C~130 . C, but after the working time continues to increase, the temperature of the mold may rise to over 130 . C, this will cause the cooling effect of the mold to be poor, so that the product may be demolded in a state that has not been completely shaped, so that the final product may have a problem of excessive deformation.
另外，雖然有一種傳統的模具本身即設計有加熱及冷卻之裝置或管路，然而模具本身設計有與製品相同形狀的模穴，因此模具上的加熱及冷卻裝置或管路設計時必須避開模穴，因此直接設置於模具上的加熱及冷卻裝置不易使得模具整體溫度均勻，而且每個不同的模具都需要設置加熱及冷卻裝置或管路，其模具的成本也較高。In addition, although there is a conventional mold itself designed with heating and cooling devices or pipes, the mold itself is designed with the same shape as the product, so the heating and cooling device or piping design on the mold must be avoided. The cavity is so that the heating and cooling device directly disposed on the mold is not easy to make the overall temperature of the mold uniform, and each of the different molds needs to be provided with a heating and cooling device or a pipe, and the cost of the mold is also high.
為解決此問題，本創作提供一種具溫控系統的中空成型機，包括有一組夾模裝置，該夾模裝置包括一第一模座及一第二模座，其特徵在於該夾模裝置更包括一溫控系統，該溫控系統包括設置於第一模座上的一第一冷卻單元與一第一加熱單元，以及設置在第二模座的一第二冷卻單元與一第二加熱單元，溫控系統進一步包括一第一溫度感測器，第一溫度感測器用來感測第一或第二模座其中任意一者的溫度。In order to solve the problem, the present invention provides a hollow molding machine with a temperature control system, comprising a set of clamping devices, the clamping device comprising a first mold base and a second mold base, wherein the clamping device is further The invention includes a temperature control system, the temperature control system includes a first cooling unit and a first heating unit disposed on the first mold base, and a second cooling unit and a second heating unit disposed on the second mold base The temperature control system further includes a first temperature sensor for sensing the temperature of any one of the first or second mold bases.
本創作利用冷卻單元配合加熱單元調整第一模座的溫度，利用冷卻單元配合加熱單元控制第二模座的溫度，進一步達到調整第一及第二模塊工作溫度的功能，進一步能夠依據加工的材質所需的工作溫度調整第一及第二模塊之工作溫度，使得本創作具溫控系統的中空成型機使用任何塑料進行加工都可獲得良好且穩定的物理性質，並且獲得良好的良率。The creation uses the cooling unit and the heating unit to adjust the temperature of the first mold base, and the cooling unit and the heating unit control the temperature of the second mold base to further adjust the working temperature of the first and second modules, and further can be processed according to the material. The required operating temperature adjusts the operating temperatures of the first and second modules, so that the hollow molding machine of the present temperature control system can be processed with any plastic to obtain good and stable physical properties and obtain good yield.
再者，本創作具溫控系統的中空成型機的第一及第二模座具有控制溫度的功能，因而與第一及第二模座結合的第一及第二模塊本身並不需額外的加熱及冷卻的管路或設備，如此能夠節省模具的成本，進一步模具本身的維修、保養也較簡易且成本低廉。Furthermore, the first and second mold bases of the hollow molding machine with the temperature control system have the function of controlling the temperature, so that the first and second modules combined with the first and second mold bases do not need additional The heating or cooling of the pipeline or equipment can save the cost of the mold, and the maintenance and maintenance of the mold itself is simple and low-cost.

C~130 . The operating temperature between C (for a suitable temperature for the polylactic acid material).
當第一及第二模座４２、７０與第一及第二模塊６３、９０溫度到達工作溫度，聚乳酸顆粒原料進入落料機構２６內加熱成熔融狀態之後，熔融狀態的聚乳酸原料由落料機構２６的末端慢速地沿第二軸向Ｙ落下形成一胚料２８，直至胚料２８沿第二軸向Ｙ具有足夠長度後（如第１圖所示），推動桿４０頂抵第一及第二模座４２、７０位移至落料機構２６下方，且造成第一模塊６３的第一模穴６４以及第二模塊９０的第二模穴９２與胚料２８對齊（如第４圖所示）之後，驅動第一及第二模塊６３、９０同時沿第三軸向Ｚ移動閉合形成閉模狀態，造成胚料２８被夾在第一模塊６３的第一模穴６４以及第二模塊９０的第二模穴９２之間，此時切料機構３４驅動切料刀３６切斷胚料２８（如第５圖所示），隨後推動桿４０連動第一及第二模座４２、７０沿第一軸向Ｘ位移至與吹氣機構３０對齊的位置，吹氣機構３０沿第二軸向Ｙ移動氣嘴３２伸入胚料２８並充氣，造成胚料２８被氣體擠壓而貼靠在第一模塊６３的第一模穴６４以及第二模塊９０的第二模穴９２表面，待胚料２８冷卻後即獲得管狀的製品。When the temperatures of the first and second die holders 42, 70 and the first and second modules 63, 90 reach the operating temperature, and the polylactic acid pellet raw material enters the blanking mechanism 26 to be heated to a molten state, the molten polylactic acid raw material falls. The end of the material mechanism 26 slowly falls along the second axial direction Y to form a blank 28 until the blank 28 has a sufficient length along the second axial direction Y (as shown in Fig. 1), and the push rod 40 abuts the first The first and second die holders 42, 70 are displaced below the blanking mechanism 26 and cause the first cavity 64 of the first module 63 and the second cavity 92 of the second module 90 to be aligned with the blank 28 (Fig. 4) After being shown, the first and second modules 63, 90 are driven to move simultaneously in the third axial direction Z to form a closed state, causing the blank 28 to be clamped to the first cavity 64 and the second module of the first module 63. Between the second cavities 92 of 90, at this time, the cutting mechanism 34 drives the cutting blade 36 to cut the blank 28 (as shown in Fig. 5), and then the push rod 40 links the first and second die holders 42, 7 Displaceing in the first axial direction X to a position aligned with the air blowing mechanism 30, the air blowing mechanism 30 moves the air nozzle 32 into the blank 28 in the second axial direction Y and inflates, causing the blank 28 to be pressed against the gas. On the surface of the first cavity 64 of the first module 63 and the second cavity 92 of the second module 90, a tubular article is obtained after the blank 28 is cooled.
當第一及第二模塊６３、９０因為接觸熔融狀態之聚乳酸的胚料２８導致溫度升高至高於工作溫度時，第一及第二溫度感測器６６、９４偵測到第一及第二模座４２、７０溫度過高（例如高於130。 C），因而溫控設備９９停止供應加熱液，溫控設備９９轉換成供應冷卻液流經第一模座４２的第一冷卻單元５２以及第二模座７０的第二冷卻單元７８，造成第一及第二模座４２、７０降溫，進一步使得第一及第二模塊６３、９０降溫，如此就能將第一及第二模塊６３、９０的溫度控制在預設的工作溫度範圍內。When the first and second modules 63, 90 cause the temperature to rise above the operating temperature due to contact with the billet 28 of the polylactic acid in the molten state, the first and second temperature sensors 66, 94 detect the first and the second 42, 70 two mold temperature is too high (e.g. greater than 130. C), the temperature control device 99 so that the supply of heating fluid, temperature control equipment converts the seat 99 to supply cooling fluid through the first die holder 42, a first cooling unit 52 And the second cooling unit 78 of the second die holder 70 causes the first and second die holders 42, 70 to cool down, further cooling the first and second modules 63, 90, so that the first and second modules 63 can be The temperature of 90 is controlled within the preset operating temperature range.
本創作利用溫控系統１２調整第一及第二模座４２、７０的溫度，進一步達到調整第一及第二模塊６３、９０工作溫度的功能，因而能夠依據加工的材質所需的工作溫度調整第一及第二模塊６３、９０之工作溫度，使得本創作具溫控系統的中空成型機２０使用任何塑料進行加工都可獲得良好且穩定的物理性質，並且獲得良好的良率。The creation uses the temperature control system 12 to adjust the temperatures of the first and second mold bases 42, 70 to further adjust the operating temperature of the first and second modules 63, 90, thereby being able to adjust according to the operating temperature required for the processed material. The operating temperatures of the first and second modules 63, 90 allow the hollow molding machine 20 of the present temperature control system to be processed using any plastic to obtain good and stable physical properties and to obtain good yield.
再者，本創作具溫控系統的中空成型機２０的溫控系統１２能調整第一及第二模座４２、７０之溫度，因而與第一及第二模座４２、７０結合的第一及第二模塊６３、９０本身並不需額外的加熱及冷卻的管路或設備，如此能夠節省模具的成本，進一步模具本身的維修、保養也較簡易且成本低廉。Furthermore, the temperature control system 12 of the hollow molding machine 20 with the temperature control system can adjust the temperature of the first and second mold bases 42, 70, and thus the first combination with the first and second mold bases 42, 70 And the second module 63, 90 itself does not need additional heating and cooling pipelines or equipment, so that the cost of the mold can be saved, and the maintenance and maintenance of the mold itself is simpler and lower in cost.
