[0031] Please refer to Figures 1-8 The utility model provides an in-mold inner cutting die, including left mould 1 and right mould 2, and the right mould 2 has injection channel 3, and the injection channel 3 is connected with injection cavity, and the right mould 2 is provided with cutter 4 and cleaning component 5, and the cutter 4 cuts the residual material in the injection channel 3, and the left mould 1 is separated from the right mould 2 in the process, and the injection channel 3 is cleaned by the cleaning component 5. Specifically, after the injection part cools, the cutter 4 cuts the residual material, the left mould 1 moves to the left and drives the injection part to move, and the right mould 2 is stationary, and the cleaning component 5 is used to make the broken residual material leave the channel 3 in the process of moving.

[0032] The right mould 2 includes detachable first part 21 and second part 22, and the first part 21 is displaced to the right side, and the first part 21 is provided with connecting groove for the entry of injection head. The second part 22 is provided with accommodating groove, the cutter 4 is located in the accommodating groove, and the oil cylinder 6 is installed in the accommodating groove, and the oil cylinder 6 is connected with the cutter 4. After the injection part cools, the oil cylinder 6 drives the cutter 4 to move and cut the residual material.

[0033] The cutter 4 is close to the position of injection cavity, first, the injection cavity is complete, and the influence of the cutter 4 is reduced, and the cutter 4 is close to the connecting place of residual material and injection part, and the residual material can be better cut off. The oil cylinder 6 is located at the right side of the cutter 4, and the wall thickness of the second part 22 corresponding to the oil cylinder 6 is relatively thick, and the influence on the oil cylinder 6 can be reduced.

[0034] The connecting plate 61 is arranged between the cutter 4 and the oil cylinder 6, the oil cylinder 6 is connected with the cutter 4 through the connecting plate 61, and the cutter 4, the connecting plate 61 and the oil cylinder 6 are detachably connected, so that the cutter 4 can be replaced conveniently after being worn out.

[0035] The shrinkage disc 7 is arranged below the cutter 4, the right side of the shrinkage disc 7 is a conical surface, the diameter of the channel 3 is reduced, the shrinkage disc 7 is composed of two semicircular clamping plates 71, and the transmission component 8 is arranged between the clamping plate 71 and the connecting plate 61 to separate the two clamping plates 71. The cutter 4 has a certain distance from the channel 3, and the cutter 4 and the clamping plate 71 can be shortened by the cutout on the clamping plate 71, and the moving distance of the cutter 4 is reduced. When in use, the oil cylinder 6 drives the cutter 4 to move, and the transmission component 8 is used to separate the two clamping plates 71, so that the residual material with reduced diameter leaks out, and the cutter 4 corresponds to the position, and the residual material can be cut conveniently.

[0036] The transmission component 8 comprises a rack 81, a gear 82 and a screw rod 83, both ends of the connecting plate 61 are fixed with the rack 81 respectively, the gear 82 is fixed with the screw rod 83, the screw rod 83 is rotationally matched with the second part 22, the rack 81 is engaged with the gear 82, and the clamping plate 71 is threadedly connected with the screw rod 83. The two side surfaces of the clamping plate 71 are limited, so that the clamping plate 71 is prevented from rotating. In use, the oil cylinder 6 moves downward, drives the connecting plate 61 to move, the connecting plate 61 drives the rack 81 to move, the rack 81 drives the gear 82 to rotate, the gear 82 drives the screw rod 83 to rotate, and the screw rod 83 drives the two clamping plates 71 to separate.

[0037] The cutter 4 is provided with a through hole 41, the cleaning component 5 comprises an air pipe 51, the air pipe 51 is fixed with the connecting plate 61, the air pipe 51 is connected with a gas pump through a hose, the gas pump is not shown in the figure, and the air pipe 51 corresponds to the through hole 41. As shown in the figure, the air pipe 51 is located in the first part 21 and above the connecting groove, so that the air pipe 51 is prevented from contacting the injection molding head. When the cutter 4 and the rack 81 are lowered by the oil cylinder 6, the air pipe 51 is also lowered. When the cutter 4 cuts off the residual material, the cutter 4 continues to descend. When the through hole 41 coincides with the axis of the channel 3, the air outlet of the air pipe 51 corresponds to the channel 3 at this time, and the left mold 1 and the right mold 2 are separated by a certain distance, and then the gas pump is started to blow the cut-off residual material out of the channel 3.

[0038] The diameter of the through hole 41 is greater than the diameter of the channel 3. In the case that the through hole 41 is slightly misaligned with the axis of the channel 3, the large-diameter through hole 41 can also cover the channel 3, without affecting the passage of the residual material, and preventing the error caused by the descent of the oil cylinder 6.

[0039] The air pipe 51 is provided with an ejection component 52, the ejection component 52 comprises a top cylinder 521, and the top cylinder 521 extends out of the air pipe 51 to eject the residual material out of the channel 3 during the separation of the left mold 1 and the right mold 2. Specifically, the top cylinder 521 is located in the air pipe 51, and the diameter of the top cylinder 521 is smaller than the diameter of the channel 3, so that the top cylinder 521 can enter the channel 3 and prevent the deviation of the descent.

[0040] The ejection component 52 further comprises a sliding plate 522, the sliding plate 522 extends upward and forms an I-beam 523 in the transverse direction, the air pipe 51 is provided with a moving through slot 511 of the top cylinder 521, the sliding plate 522 comprises an upper sliding plate 5221 and a lower sliding plate 5222, the lower sliding plate 5222 is fixedly connected with the top cylinder 521 through the through slot 511, both ends of the top cylinder 521 are penetrated, and the top cylinder 521 is used for gas passing, the lower sliding plate 5222 is slidably connected with the upper sliding plate 5221 in the longitudinal direction, and the lower sliding plate 5222 is limited in the transverse direction by the upper sliding plate 5221, the left mold 1 is fixed with a pull plate 11, an end portion of the pull plate 11 is bent to form a contact portion 111 located in the range of the I-beam 523, and the first part 21 is provided with a space for the sliding plate 522 to move.

[0041] During use, after the cutter 4 cuts off the residual material and the through hole 41 coincides with the axis of the channel 3, the left mold 1 drives the card plate to move during the process of leaving the right mold 2. After moving to a certain distance, the contact part 111 of the pull plate 11 contacts the I-plate 523, pulling the I-plate 523. The I-plate 523 drives the upper slide 5221 and the lower slide 5222 to move together. The lower slide 5222 drives the ejector 521 to extend from the air pipe 51 and insert into the channel 3 to eject the cut material. During the process of the ejector 521 extending, the air pump is started to inflate the air pipe 51. The gas first enters the air pipe 51 and then enters the ejector 521. The ejector 521 cooperates with the air pump to eject the residual material while also cleaning the channel 3.

[0042] It should be noted that when the left mold 1 approaches the right mold 2, the contact portion 111 on the pull plate 11 and the other end of the I-plate 523 restore it to its initial position. During this process, the lower slide 5222 drives the top cylinder 521 to recover. When the left mold 1 and the right mold 2 are merged, the cylinder 6 starts to move upward, and the channel 3 is restored to the injection state.

The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
