During use, the cooling liquid enters the interior of mold A201 and mold B202 through the circulation pipes, which can achieve rapid cooling of the injection molded parts.

[0045] Among them, a discharge part 3 is welded on the mold B202, and the discharge part 3 is composed of a sleeve 301, a liquid inlet pipe 302, a discharge rod 303, a baffle 304, a force rod 305, a liquid inlet hole 306, a first auxiliary block 307, a slot 308, a protrusion 309, a second electric cylinder 310, a driving block 311 and a coil spring 312. A sleeve 301 is welded on the left end face of the mold B202, and the sleeve 301 is not connected to the hollow part inside the mold B202. A liquid inlet pipe 302 is welded on the sleeve 301, and the liquid inlet pipe 302 is connected to the sleeve 301, and the liquid inlet pipe 302 is connected to the injection liquid supply equipment.

[0046] Among them, a discharge rod 303 slides inside the sleeve 301, and the discharge rod 303 is a stepped shaft structure, and the discharge rod 303 slides on the mold B202; six liquid inlet holes 306 are opened in a circular array inside the mold B202; a concave baffle 304 is welded on the discharge rod 303, and a coil spring 312 is sleeved on the discharge rod 303, and the left end of the coil spring 312 is elastically in contact with the baffle 304, and the right end of the coil spring 312 is elastically in contact with the sleeve 301.

[0047] Among them, a second electric cylinder 310 is fixed to the left end face of the mold B202, and a driving block 311 is welded to the protruding end of the second electric cylinder 310. The driving block 311 slides on the unloading rod 303, and the right end face of the driving block 311 contacts the baffle 304. When the injection liquid needs to be added, the second electric cylinder 310 is controlled to contract, and the second electric cylinder 310 drives the driving block 311 to move to the right. Under the push of the driving block 311, the baffle 304 drives the unloading rod 303 to move to the right. At this time, the liquid inlet hole 306 is unblocked, and the injection liquid in the sleeve 301 enters the gap between the mold A201 and the mold B202 through the liquid inlet hole 306. The same operation can be used for unloading when unloading after the injection molding is completed.

[0048] When the first electric cylinder 204 contracts, the unloading rod 303 contacts the left end surface of the inner wall of the seat body 1. During the mold opening process, the unloading rod 303 moves to the right under the obstruction of the seat body 1 to push out the finished part in the mold B202.

[0049] Among them, the baffle 304 is a concave structure, and a force-bearing rod 305 is welded on the front end face and the rear end face of the inner wall of the baffle 304. The two force-bearing rods 305 are both cylindrical rod-shaped structures. The inner ends of the two force-bearing rods 305 are polished. After polishing, the inner ends of the two force-bearing rods 305 are both arc-shaped structures; the front end and the rear end of the mold B202 are welded with a first auxiliary block 307 of a rectangular block structure, and each first auxiliary block 307 has a Slots 308 are provided in a linear array, and protrusions 309 are welded on each first auxiliary block 307 in a linear array. The protrusions 309 and the slots 308 are arranged in a staggered manner. The two force-bearing rods 305 are engaged with the slots 308. When the unloading rod 303 moves to the right for unloading, the two force-bearing rods 305 are continuously engaged with the slots 308. When the force-bearing rods 305 are continuously engaged with the slots 308, vibrations are generated, which can assist unloading.

[0050] Among them, a connecting block 102 is rotated in the middle position of the front end face and the rear end face of the seat body 1, and the two connecting blocks 102 are welded to the base 103; a groove 105 with a rectangular groove structure is opened on the front end face of the seat body 1; an auxiliary part 4 is welded on the mold B202, and the auxiliary part 4 is composed of a mounting arm 401 and a second auxiliary block 402. A mounting arm 401 is welded on the front end face of the mold B202, and a second auxiliary block 402 is welded at one end below the mounting arm 401. The second auxiliary block 402 is a rectangular block structure, and the top end surface of the second auxiliary block 402 is polished. After the polishing treatment, the second auxiliary block 402 The top surface is an arc-shaped structure; the top surface of the second auxiliary block 402 contacts the bottom surface of the base body 1. At this time, the base body 1 is in a horizontal state, and the second auxiliary block 402 is located at the left side of the groove 105. When the second auxiliary block 402 moves to the left, the second auxiliary block 402 is located inside the groove 105. When the mold is opened, the mounting arm 401 and the second auxiliary block 402 follow the mold B202 to move to the left. When the second auxiliary block 402 moves to the position of the groove 105, the base body 1 loses support. At this time, the base body 1 tilts to the right. At this time, the base body 1 will hit the base 103, and vibration can be generated through the collision, and the auxiliary unloading action can be completed through this vibration.

[0051] Among them, two rectangular block-shaped wooden blocks 104 are fixed to the top surface of the base 103. The two wooden blocks 104 are aligned with the two corners below the base 1. When the base 1 tilts left or right, it will contact the wooden blocks 104, which can reduce the degree of damage to the base 1.

[0052] Embodiment 2:

[0053] On the basis of the first embodiment, the elastic force of the coil spring 312 is greater than the resistance of the two force-bearing rods 305 engaging with the locking grooves 308 . During use, the force-bearing rod 305 can be reset to the left under the push of the elastic force of the coil spring 312 .

[0054] Working principle: Control the first electric cylinder 204 to extend, and when the first electric cylinder 204 extends, it pushes the mold B202 to move to the right to complete mold closing; after mold closing, inject molding liquid into the gap between mold A201 and mold B202, control the second electric cylinder 310 to contract, and the second electric cylinder 310 drives the driving block 311 to move to the right, and under the push of the driving block 311, the baffle 304 drives the unloading rod 303 to move to the right, at this time, the liquid inlet hole 306 is unblocked, and the injection molding liquid in the sleeve 301 enters the gap between mold A201 and mold B202 through the liquid inlet hole 306; start the cooling liquid circulation pump, and the cooling liquid enters the mold A201 and mold B202 to circulate to cool the injection molding liquid; after cooling, control the first electric cylinder 204 to contract, and the first electric cylinder 204 drives the mold B202 to move to the left to open the mold, and when the mold B202 moves to the left, the seat body 1 blocks the unloading rod 303, and at this time the unloading rod 3 03 pushes the finished parts to fall and completes unloading; while the unloading rod 303 moves to the right to unload, the two force-bearing rods 305 are continuously engaged with the slots 308. When the force-bearing rods 305 are continuously engaged with the slots 308, vibration will be generated, and unloading can be assisted by this vibration; at the same time, when the mold is opened, the mounting arm 401 and the second auxiliary block 402 follow the mold B202 to move to the left. When the second auxiliary block 402 moves to the position of the groove 105, the seat body 1 loses support. At this time, the seat body 1 tilts to the right. At this time, the seat body 1 will hit the base 103, and vibration can be generated through the collision. The auxiliary unloading action can be completed through this vibration; after the left end of the unloading rod 303 is damaged, the unloading can also be completed by controlling the second electric cylinder 310 to contract. When the second electric cylinder 310 contracts, it drives the driving block 311 to move to the right. Under the push of the driving block 311, the baffle 304 and the force-bearing rod 305 move to the right to complete the unloading.
