Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-3 A molding die, comprising:

[0024] The upper template 1 and the lower template 2 are provided. The top of the upper template 1 has an installation groove 4, and a mold structure 7 is installed in the installation groove 4. Multiple fixed guide pillars 14 are installed inside the upper template 1. Fixed push plates 13 are sleeved on the corresponding fixed guide pillars 14. Fixed racks 12 are fixedly connected to the side walls of each fixed push plate 13. Fixed gears 11 that mesh with the corresponding fixed racks 12 are rotatably installed on the inner wall of the lower template 2. Fixed gears 11, fixed racks 12 and fixed guide pillars 14 play a role in stabilization and guidance. A hydraulic cylinder 20 is fixedly connected to the lower inner wall of the lower template 2. The output end of the hydraulic cylinder 20 is fixedly connected to the corresponding fixed push plate 13. An extrusion structure 15 is also installed on the lower template 2 and is connected to the mold structure 7. Multiple heating pipe interfaces 3 are installed on the side walls of the upper template 1.

[0025] The sheet material is placed into the feeding rack 10 by the sheet feeding machine, and then the sheet material in the feeding rack 10 is transferred to the mold structure 7. Then the resin is put into the extrusion structure 15.

[0026] The mold structure 7 includes an upper mold 71 and a lower mold 72, which are fixedly snapped together. A fixed frame is pressed between the upper mold 71 and the lower mold 72, and multiple fixed springs 76 are fixedly connected between the upper mold 71 and the lower mold 72. A fixed handle 73 is fixedly snapped onto one side of the upper mold 71, and multiple corresponding fixed flow channels 75 are opened on the upper mold 71 and the lower mold 72.

[0027] After the upper mold 71 and the lower mold 72 are closed, the copper frame inside is pressed tightly. At this time, the fixing spring 76 is compressed. After the plastic sealing is completed, the upper mold 71 and the lower mold 72 are separated. Under the action of the fixing spring 76, the PIN pins at each position will automatically disengage from the product.

[0028] The extrusion structure 15 includes an extrusion rod 17. The top end of the fixed push plate 13 is slidably connected to a locking block 18 corresponding to the extrusion rod 17. The bottom end of the extrusion rod 17 is fixedly connected to a fixing block 19. The extrusion rod 17 is connected to the locking block 18 through the fixing block 19. The fixing block 19 and the locking block 18 are provided with ball bearings to facilitate installation and adjustment. The top end of the extrusion rod 17 is fixedly connected to an injection head 16. The injection head 16 is connected to the fixed flow channel 75. The injection head 16 is a consumable. In case of wear, the injection head 16 and the extrusion rod 17 are ejected and then rotated 90 degrees to remove and replace it.

[0029] The mold structure 7 is equipped with a feeding rack 6 and a discharging rack 10, and each discharging rack 10 is fixedly connected with a corresponding operating handle 9.

[0030] Multiple positioning blocks 74 are installed on the top of the upper mold 71, and multiple fixed guide sleeves 5 are fixedly installed on the top of the upper template 1, with the multiple fixed guide sleeves 5 installed at the corners of the upper template 1.

[0031] Each mounting slot 4 is slidably engaged with a fixing block 8, which is used to fix the mold structure 7.

[0032] In this invention, the product is first placed in the feeding rack 10, and the feeding rack 10 is used to arrange the product onto the mold structure 7. Then, the sheet material is fed into the feeding rack 10 by the sheet feeding machine. The feeding rack 10 is then placed in the mounting slot 4. The sheet material in the feeding rack 10 is then transferred into the mold structure 7 by the operating handle 9. The feeding rack 10 is then removed, and resin is added to the extrusion structure 15. After the heated material melts, the hydraulic cylinder 20 mechanically extrudes the resin. The extrusion rod 1 of the extrusion structure 15... The glue inside 7 is squeezed into the fixed flow channel 75, and then enters each cavity through the extrusion structure 15 to finally form the product. After completion, the oil cylinder 20 descends, the extrusion rod 17 and the injection head 16 retract into the barrel, and after the upper mold 71 and the lower mold 72 close, the copper frame inside is pressed tightly. At this time, the fixing spring 76 is compressed. After the molding is completed, the upper mold 71 and the lower mold 72 separate. Under the action of the fixing spring 76, the pins at each position will automatically detach from the product, completing the molding process.
