New description: [New technical field] This creation department is related to the mold equipment for manufacturing plastic containers, especially for the opening and closing of a mold opening and closing machine which can be used for blow molding machines accurately and quickly. Mold device. - [Prior Art] Press, most of the current plastic containers are made by molding. _ The so-called molding refers to placing the blank in the mold cavity of two corresponding mold halves, and then the two mold halves are mutually aligned (closed) by the opening and closing mechanism, so that the billet is at the temperature. Under the change of pressure, etc., it is formed into a product corresponding to the shape of the cavity, and then the two mold halves (opening mold) are opened by the opening and closing mechanism to take out the molded product. Since the molding of the billet usually has to be done by means of pressure changes, and this pressure generates the force of opening the two mold halves, the aforementioned opening and closing mold mechanism usually has the effect of closing or clamping. . > For example, the new patent of "The Closed Mold of Hollow Forming Die. Device" is disclosed in Patent No. 381539, which has two fixed mold bases, and a plurality of guide rods are arranged between the two fixed mold bases, and Two sliding mold bases are arranged on the sliding rod, two side modules are arranged between the two sliding mold bases, and a locking device is arranged between the fixed mold base and the sliding mold base, the locking device has a toggle device and is used for driving the same A driving device of the toggle device, which may be a pneumatic cylinder or a hydraulic cylinder to drive the sliding mold base to close or mold the two side modules. This patented closed-mold device uses a pneumatic cylinder or a hydraulic cylinder as the moving 5 M333294. Faster C-cylinder or / by genus red as the power source, the advantage is the speed of movement - == lower cylinder or oil * shock II ; ϊ 模 模 县 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Pu and storage are easy to waste energy. Source 2 has improved these problems. At present, the industry often uses all-electric power servo motors to replace the pressure oil pressure b. For example, China's special report No. M257273 "_The molding machine's control mold opening and closing drive new patent" Four guide rods are extended from the base, and the outer mold base and the closed seat of each guide rod 2 are provided with a servo motor, and the second service motor drives a lead screw through the timing belt set. The screw 盥 is moved and screwed, and the moving seat is connected with the base and the inner mold base by a plurality of connecting rods. = The motor can be controlled by the control ship motor. (4) Opening and closing of the mold 0 The aforementioned "plastic forming machine" The driving device for controlling the opening and closing of the mold" The new patent is driven by the ship motor through the timing belt set to drive the 7 mold opening structure material, which can indeed reach the position of the (4) opening and closing mold position, and does not cause unnecessary shock. However, if the motor is driven by the belt, the transmission of the lead screw will produce a considerable reduction ratio. This will make the movement of the opening and closing mold slower, and the use of the lead screw has the advantage of (10) precision. The tolerance to the axial force is poor', which will cause the lead screw to deteriorate. In the case of blow molding machines for the production of plastic containers, the current technology can open and close the molds every 6 M333294 minutes up to 15~2 times, in other words, from placing the blanks, clamping, blow molding to mold opening. The time of the product is only about 3~4 seconds. Therefore, for the blow molding machine, the opening and closing time must be completed in less than one second. The servo motor drives the lead screw through the timing belt set. In order to control the structure of the mold opening and closing, the speed of opening and closing the mold may be difficult to meet the needs of the blow molding machine. Therefore, for the blow molding machine, the above-mentioned driving device for opening and closing the mold is necessary to be further improved. [New content] The main purpose of this creation is to solve the above problems and provide an opening and closing mold device for a blow molding machine capable of quickly and accurately opening and closing a mold. The second purpose of this creation is that the auxiliary clamping mechanism can fine-tune the position of the two mold halves to ensure the clamping effect of the two mold halves. For the purpose of the foregoing, the opening and closing mold device of the present invention is provided with two seats on the blow molding machine, and one or more movable seats are slid between the two bodies, and the live seat and one of the bodies or the other The opposite side of the movable seat is respectively provided with a 'and a connecting rod mechanism is arranged between the movable seat and the corresponding seat body, and the connecting mechanism is driven by a driving mechanism, and the driving mechanism is driven by a servo motor & Then, the link mechanism is linked by a link group to drive the movable seat to perform the opening and closing action. The servo motor has the characteristics of precise positioning, and the servo motor is the sound of the sound. The rod group directly drives the link mechanism to open and close the mold, so the opening and closing mold is quite fast, and can meet the requirements of the quick opening and closing mold. Therefore, this creation has a quick and sturdy function. The auxiliary clamping mechanism has a pressing chamber between the movable seat or the seat and the clamping back plate 7 M333294, and can be pressed into the two mold halves by injecting high-pressure air to finely adjust the position of the clamping back plate. This allows the two mold halves to achieve the correct clamping effect. The above and other objects and advantages of the present invention will become more apparent from the detailed description and the accompanying drawings. - Of course, this creation is tolerated on certain parts or arrangements of parts, but the selected embodiments are described in detail in the present specification and their construction is shown in the drawings.
