[0034] Embodiment one

[0035] As Figures 4-8As shown, in this embodiment, a first inclined seat 321 is fixedly connected to one side of the first side mold 320, and a second inclined seat 331 is fixedly connected to one side of the second side mold 330. Both the second inclined seat 331 and the first inclined seat 321 are slidably connected to the bottom mold base 300. A pressing seat 410 is fixedly connected to the bottom surface of the top mold base 400 at positions corresponding to the second inclined seat 331 and the first inclined seat 321. The pressing seat 410 is used to press the second inclined seat 331 and the first inclined seat 321. One end of the first inclined seat 321 and the second inclined seat 331 is inwardly... Each wall has an internal hole 323, and a return spring is fixedly connected to the inner wall of the internal hole 323. One end of the return spring contacts the outer wall of the core mold 310. The top of the inclined seat 1 321 and the inclined seat 2 331 are both provided with inclined holes 322. Each side of the multiple extrusion seats 410 is provided with a rod 420. The top of the rod 420 is fixedly connected to the top mold seat 400. It also includes a receiving plate 500, which is fixedly connected to the top of the injection mold template 200. The top of the receiving plate 500 is fixedly connected to the top of the core mold 200. Multiple base rods 510 are connected, and mold rods 520 are slidably connected to the top of the base rods 510. Multiple side slots 312 are opened on the outer side of the core mold 310. The multiple mold rods 520 correspond one-to-one with the multiple side slots 312. The top of the mold rod 520 is slidably connected to the corresponding side slot 312. The mold rods 520 are used to form the inner longitudinal partition 710 within the upper shell 700. A shrinkage template 800 is slidably connected to the top of the receiving plate 500, and the bottom of the shrinkage template 800... Each of the multiple base rods 510 has a slot, which is used to move the mold rod 520. The shrinking mold plate 800 is fixedly connected to the top mold base 400. The angle between the base rod 510 and the mold rod 520 above it is less than 180 degrees. Cooling pipes are provided inside the top mold base 400 and the bottom mold base 300. Positioning pins are fixedly connected to the four top corners of the bottom mold base 300. Limiting holes that cooperate with the positioning pins are provided at the four top corners of the bottom surface of the top mold base 400.

[0036] In this embodiment, when the top mold base 400 moves downward, the pressing seat 410 presses the inclined seat 331 and the inclined seat 321 together. When the top mold base 400 moves upward, the inclined seat 321 and the inclined seat 331 move outward under the action of their respective return springs. The setting of the insert rod 420 and the inclined hole 322 facilitates the positioning of the inclined seat 321 and the inclined seat 331. When the hydraulic rod 600 drives the top mold base 400 to move upward, it simultaneously drives the shrinking template 800 to move upward. When the shrinking template 800 moves upward to contact the mold rod 520, the inclined setting of the mold rod 520 causes the shrinking template 800 to continue to move upward, driving the mold rod 520 to move laterally. This causes the top of the mold rod 520 to separate from the inner longitudinal partition 710, preventing the mold rod 520 from hooking with the upper shell 700 and hindering the upper shell 700 from falling off.
