The deburring component 34 includes an electric cylinder 341 vertically disposed at the top of the plastic part receiving box 33, a rubber pressing block 342 disposed at the actuating end of the electric cylinder 341 and located inside the plastic part receiving box 33, and a grinding plate 343 embedded on the upper surface of the L-shaped limiting plate 371.

[0045] It should be noted that, in this embodiment, before the plastic part translation and unloading device 30 is put into operation, the lifting plate 32 is adjusted to a suitable height by the first telescopic cylinder 31, and the adjusting rod 372 is rotated to move the L-shaped limiting plate 371 until the distance between the two L-shaped limiting plates 371 is less than the width of the molded plastic part.

[0046] During the translational unloading, the second telescopic cylinder 39 drives the liquid storage box 381 and the plastic part receiving box 33 to move. When the plastic part receiving box 33 moves to the point where the molded plastic part is located in the plastic part receiving box 33, the push plate lifting device 20 resets. At this time, the ejector pin resets, and the plastic part falls on the L-shaped limiting plate 371. The second telescopic cylinder 39 continues to drive the liquid storage box 381 and the plastic part receiving box 33 to move so that the plastic part leaves the mold. During this process, the gate solidified material cutting component 35 can remove the gate solidified material at the top of the plastic part, and the mold release agent spraying component 38 can spray the mold release agent. During the process of the second telescopic cylinder 39 driving the plastic part receiving box 33 to reset, the lifting scraping device 40 moves the molded plastic part out of the plastic part receiving box 33. When it is moved out, the pressing deburring component 34 can remove the burrs at the bottom of the plastic part.

[0047] Furthermore, when the gate solidified material cutting component 35 is working, the cylinder 351 drives the cutter 352 to move, and the two cutters 352 cooperate to cut the gate solidified material.

When the mold release agent passes through the guide box 383, the heat conduction block 361 conducts the heat of the plastic part to the mold release agent to heat the mold release agent.

[0049] Furthermore, when the deburring component 34 is working, the electric cylinder 341 drives the rubber pressing block 342 to press down on the plastic part.

[0051] The controller model is "KV-N40DTP", the first ranging sensor 272 is "LR30XCF10LUM", and the second ranging sensor 274 is "LR30XCF10LUM".

[0052] After the injection molding and cooling of the mold at the top of the injection molding machine base housing 10, the mold opens. At this time, the ejector plate lifting device 20 lifts the mold ejector plate, and the ejector pins on the ejector plate drive the molded plastic part to leave the cavity. The plastic part translation and unloading device 30 moves in parallel to receive the molded plastic part leaving the cavity and drive the molded plastic part to leave the mold. When the plastic part translation and unloading device 30 is reset, the lifting scraper device 40 scrapes the molded plastic part out of the plastic part translation and unloading device 30 to complete the unloading of the plastic part.

[0053] When the lifting scraper device 40 is working, the pneumatic cylinder 41 drives the L-shaped scraper 42 to extend from the bottom of the plastic part receiving box 33 into the plastic part receiving box 33. When the plastic part receiving box 33 is reset, the L-shaped scraper 42 moves the molded plastic part out of the plastic part receiving box 33.

[0054] When the push plate lifting device 20 is working, the actuator of the drive component 26 drives the lifting tube 24 to rise and fall so that the total length of the outer tube 22 and the lifting tube 24 meets the working requirements. At this time, the drive cylinder 21 is activated, and the actuator of the drive cylinder 21 drives the outer tube 22 and the lifting tube 24 to move upward. The elastic buffer component 25 lifts the mold push plate.

[0055] When the drive component 26 is working, the stepper motor 262 drives the drive gear 263 to rotate, the drive gear 263 drives the tooth wall threaded ring 261 to rotate, and the tooth wall threaded ring 261 drives the lifting tube 24 to rise and fall through the thread.

[0056] When the elastic buffer component 25 is working, the push rod 252 pushes up the mold push plate, and the spring 253 provides elastic buffer to the push rod 252.

[0057] The controller receives the buffer displacement data of the push rod 252 measured by the first distance sensor 272, and adds the buffer displacement data to the displacement data of the drive cylinder 21 actuator measured by the second distance sensor 274, until the sum of the displacement data and the buffer displacement data is the set displacement amount, so as to ensure that the plastic part is accurately lifted. The displacement data measured by the second distance sensor 274 is the distance information between the push rod 252 and the stepper motor 262.

[0058] Before the plastic part translation and unloading device 30 is put into operation, the lifting plate 32 is adjusted to a suitable height by the first telescopic cylinder 31, and the adjusting rod 372 is rotated to move the L-shaped limiting plate 371 until the distance between the two L-shaped limiting plates 371 is less than the width of the molded plastic part.

[0059] During the translational unloading, the second telescopic cylinder 39 drives the liquid storage box 381 and the plastic part receiving box 33 to move. When the plastic part receiving box 33 moves to the point where the molded plastic part is located in the plastic part receiving box 33, the push plate lifting device 20 resets. At this time, the ejector pin resets, and the plastic part falls on the L-shaped limiting plate 371. The second telescopic cylinder 39 continues to drive the liquid storage box 381 and the plastic part receiving box 33 to move so that the plastic part leaves the mold. During this process, the gate solidified material cutting component 35 can remove the gate solidified material at the top of the plastic part, and the mold release agent spraying component 38 can spray the mold release agent. During the process of the second telescopic cylinder 39 driving the plastic part receiving box 33 to reset, the lifting scraping device 40 moves the molded plastic part out of the plastic part receiving box 33. When it is moved out, the pressing deburring component 34 can remove the burrs at the bottom of the plastic part.

[0060] When the gate solidified material cutting component 35 is working, the cylinder 351 drives the cutter 352 to move, and the two cutters 352 cooperate to cut the gate solidified material.

[0061] When the mold release agent spraying component 38 is working, the mold release agent is introduced through the raw material pipe 384. The mold release agent is sprayed out through the guide box 383, the liquid storage box 381 and the nozzle 382. When the mold release agent passes through the guide box 383, the heat conduction block 361 conducts the heat of the plastic part to the mold release agent to heat the mold release agent.

[0062] When the deburring component 34 is working, the electric cylinder 341 drives the rubber pressing block 342 to press down on the plastic part. During the process of the plastic part being moved out of the plastic part receiving box 33, the grinding plate 343 rubs the bottom of the plastic part to remove burrs.
