Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a front mold inclined ejector device of a plastic product mold. Background Art

[0002] Plastic is a very common material, and the products made from it are widely used. Plastic products are usually produced in injection molds, and the front mold inclined ejector is an indispensable and important mechanism in the mold. Its main function is to perform oblique ejection in places where the buckle position cannot be demolded. It has two main purposes: one is to move in a direction parallel to the buckle position to disengage the undercut, and the other is to perform a vertical ejection function to eject the product.

[0003] The inclined ejector plate of the current front mold can only move in a coordinated horizontal direction, and its position cannot be adjusted in the front and back directions. Sometimes, the buckle position of the plastic product is not at a specific position point, but is biased towards the front and back position of the inclined ejector plate. At this time, it cannot be ejected in coordination, and the position of the lower mold can only be adjusted so that the buckle position of the placed plastic product corresponds to the position of the inclined ejector plate. The operation is relatively complicated and the work efficiency is low.

[0004] Therefore, in view of the fact that the inclined top plate in the above-mentioned front mold inclined top device cannot adjust the front and rear positions, a front mold inclined top device can be designed that can flexibly adjust the front and rear positions of the inclined top plate to match the use of plastic products with different buckle positions, avoid the complicated operation of adjusting the lower mold position, and improve work efficiency. Utility Model Content

[0005] In order to overcome the problem that the inclined ejector plate in the front mold inclined ejector device cannot adjust the front and rear positions, it is necessary to perform complex operations to adjust the lower mold position when using plastic products with different buckle positions, thereby reducing work efficiency.

[0006] The technical solution of the utility model is as follows: a front mold inclined top device of a plastic product mold, comprising a rectangular frame; further comprising a sliding plate, a smooth penetration rod and a threaded rod, sliding plates are symmetrically arranged at the left and right ends of the inner side of the rectangular frame, inclined top plates are symmetrically arranged at the bottom of the two sliding plates, the upper ends of the two inclined top plates are movably penetrated by a smooth penetration rod, the middle outer sides of the smooth penetration rod are fixedly connected with a fixed block, the front and rear sides of the bottom of the rectangular frame are fixedly connected with a fixed plate, a threaded rod is rotatably connected between the two fixed plates, the threads of the threaded rod are penetrated and connected to the upper end of the fixed block, a motor is fixedly installed on the front fixed plate, the lower middle end of the inner side of the rectangular frame is fixedly connected to a limiting plate, the output shaft of the motor and the threaded rod are fixedly connected, and a base is arranged below the rectangular frame.

[0007] Preferably, when there is a front-to-back deviation between the two symmetrical buckle positions on the placed plastic product and the bottom of the inclined top plate, the motor can be started to drive the threaded rod to rotate, and then drive the fixed block to move forward and backward, and the inclined top plates on both sides are driven to adjust their front-to-back positions through the smooth through-rod to correspond to the positions of the buckle positions on the plastic product, thereby enhancing the versatility of the device, making the operation convenient and simple, and improving work efficiency.

[0008] Preferably, a limiting groove is provided at the bottom of the sliding plate, a guide rod is rotatably connected in the limiting groove, a sliding block is slidably connected to the outside of the guide rod, and the bottom of the sliding block is fixedly connected to the upper end of the corresponding inclined top plate. When the smooth through rod drives the inclined top plates on both sides to move back and forth, the sliding block slides back and forth on the outside of the guide rod, thereby always keeping the horizontal and vertical positions between the inclined top plate and the sliding plate unchanged.

[0009] Preferably, the thickness of the fixed block is set to be the same as the thickness of the inclined top plate, and the length of the threaded rod is set to be the same as the length of the guide rod, so that when the fixed block moves to the end position of the threaded rod, the sliding block will also reach the end position of the guide rod and will not collide with the inner wall of the sliding plate and cause impact damage.

[0010] Preferably, six vertical cylinders are fixedly connected to the upper end of the base, and a top rod is movably inserted into each vertical cylinder. A spring is fixedly connected between the bottom of each top rod and the base. The upper end of the top rod supports the placed plastic products, and the spring provides supporting force in the vertical direction, cooperating with the inclined top plate to extrude and fix the plastic products.

[0011] Preferably, support seats are fixedly connected to both sides of the upper end of the base, cylinders are fixedly installed on the upper ends of the two support seats, and the movable ends of the two cylinders are fixedly connected to support plates. The two support plates are respectively fixedly connected to both sides of the bottom of the rectangular frame. When the two cylinders are started at the same time, the height position of the rectangular frame can be lifted through the support plates, and then the inclined top plate can slowly release from the pressure on the plastic product.

[0012] Preferably, the inner side of the rectangular frame is rotatably connected to a bidirectional screw, and the two sliding plates are symmetrically threadedly connected to the outer sides of the two ends of the bidirectional screw. When the bidirectional screw rotates, it drives the two sliding plates to move relatively close to each other, and at this time drives the two inclined top plates to move relatively close to each other, and disengage from the buckle position where the plastic product is inserted.

[0013] Preferably, the left end of the bidirectional screw is fixedly connected to a rotating shaft, the left end of the rotating shaft movably passes through the rectangular frame and is fixedly connected to a gear, one side of the gear is meshed with a rack, the lower end of the rack is fixedly connected to a connecting frame, one side of the connecting frame is fixedly connected to the upper part of the fixed end of the left cylinder. When the cylinder lifts the rectangular frame, the position of the rack is inconvenient, which drives the gear to rotate, thereby driving the bidirectional screw to rotate.

[0014] Beneficial effects of the utility model:

[0015] 1. This device is equipped with a sliding plate, a smooth through-rod, and a threaded rod. When there is a front-to-back deviation between the two symmetrical buckle positions on the placed plastic product and the bottom of the inclined top plate, the motor can be started to drive the threaded rod to rotate, and then drive the fixed block to move back and forth. The smooth through-rod drives the inclined top plates on both sides to adjust their front-to-back positions to correspond to the positions of the buckle positions on the plastic product. The device can be used with plastic products in different buckle positions, has strong flexible adjustment capabilities, high versatility, and is easy to operate, thereby improving work efficiency.

[0016] 2. This device is equipped with a cylinder, a support plate, a bidirectional screw, a rotating shaft, a gear, a rack, a sliding block, a vertical cylinder, a push rod, a spring, etc. The height of the rectangular frame is controlled by the cylinder, and then the inclined top plate cooperates with the push rod to support or detach the plastic product. In the process of the rectangular frame rising, the gear is driven to rotate by the rack, and then the bidirectional screw is rotated to control the two inclined top plates to be relatively close to each other and detach from the buckle position of the plastic product, so as to achieve the effect of quickly demoulding and ejecting the plastic product, thereby improving work efficiency.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See also Figures 1-4 The utility model provides an embodiment: a front mold inclined top device of a plastic product mold, comprising a rectangular frame 1; further comprising a sliding plate 2, a smooth penetrating rod 4 and a threaded rod 7. The sliding plates 2 are symmetrically arranged at the left and right ends of the inner side of the rectangular frame 1, and the bottoms of the two sliding plates 2 are symmetrically provided with inclined top plates 3. The upper ends of the two inclined top plates 3 are movably penetrated by a smooth penetrating rod 4. The middle outer side of the smooth penetrating rod 4 is fixedly connected to a fixed block 5. The front and rear sides of the bottom of the rectangular frame 1 are fixedly connected to a fixed plate 6. A threaded rod 7 is rotatably connected between the two fixed plates 6. The thread of the threaded rod 7 is penetrated and connected to the upper end of the fixed block 5. The front fixing plate 6 is fixedly installed with a motor 8, and the lower end of the inner middle part of the rectangular frame 1 is fixedly connected to the limit plate 24. The output shaft of the motor 8 and the threaded rod 7 are fixedly connected. A base 9 is provided under the rectangular frame 1. When there is a front-to-back deviation between the two symmetrical buckle positions on the placed plastic product and the bottom of the inclined top plate 3, the motor 8 can be started to drive the threaded rod 7 to rotate, and then drive the fixed block 5 to move forward and backward. The inclined top plates 3 on both sides are driven to adjust their front and back positions through the smooth through rod 4 to correspond to the position of the buckle positions on the plastic products for use in conjunction, thereby enhancing the versatility of the device, and making the operation convenient and simple, thereby improving work efficiency.

[0024] See also Figure 1 , Figure 2 and Figure 4 In this embodiment, a limiting groove 18 is provided at the bottom of the sliding plate 2, and a guide rod 19 is rotatably connected in the limiting groove 18. A sliding block 20 is slidably connected to the outside of the guide rod 19. The bottom of the sliding block 20 is fixedly connected to the upper end of the corresponding inclined top plate 3. When the smooth through rod 4 drives the inclined top plates 3 on both sides to move back and forth, the sliding block 20 slides back and forth on the outside of the guide rod 19, thereby always keeping the horizontal and vertical positions between the inclined top plate 3 and the sliding plate 2 unchanged. The thickness of the fixed block 5 is set to be the same as the thickness of the inclined top plate 3, and the length of the threaded rod 7 is set to be the same as the guide rod 1. 9 has the same length, so that when the fixed block 5 moves to the end position of the threaded rod 7, the sliding block 20 will also reach the end position of the guide rod 19, and will not collide with the inner wall of the sliding plate 2 to cause impact damage. The upper end of the base 9 is fixedly connected with six vertical cylinders 21, and each vertical cylinder 21 is movably inserted with a top rod 22. A spring 23 is fixedly connected between the bottom of each top rod 22 and the base 9. The upper end of the top rod 22 supports the placed plastic products, and the spring 23 provides supporting force in the vertical direction, and cooperates with the inclined top plate 3 to extrude and fix the plastic products.

[0025] See also Figure 2-Figure 3In this embodiment, support seats 10 are fixedly connected to both sides of the upper end of the base 9, and cylinders 11 are fixedly installed on the upper ends of the two support seats 10. The movable ends of the two cylinders 11 are fixedly connected to support plates 12. The two support plates 12 are respectively fixedly connected to the bottom sides of the rectangular frame 1. When the two cylinders 11 are started at the same time, the height position of the rectangular frame 1 can be lifted by the support plates 12, and then the inclined top plate 3 slowly breaks away from the pressing of the plastic product. The inner side of the rectangular frame 1 is rotatably connected with a bidirectional screw 13, and the two sliding plates 2 are symmetrically threadedly connected to the outer sides of the two ends of the bidirectional screw 13. The bidirectional screw 13 rotates When the two sliding plates 2 are moved relatively close to each other, the two inclined top plates 3 are driven to move relatively close to each other and disengage from the buckle position where the plastic product is inserted. The left end of the bidirectional screw 13 is fixedly connected to the rotating shaft 14. The left end of the rotating shaft 14 movably passes through the rectangular frame 1 and is fixedly connected to the gear 15. One side of the gear 15 is meshed with the rack 16. The lower end of the rack 16 is fixedly connected to the connecting frame 17. One side of the connecting frame 17 is fixedly connected to the upper part of the fixed end of the left cylinder 11. When the cylinder 11 lifts the rectangular frame 1, the position of the rack 16 is inconvenient, which drives the gear 15 to rotate, thereby driving the bidirectional screw 13 to rotate.

[0026] During operation, when there is a front-to-back deviation between the two symmetrical buckle positions on the placed plastic product and the bottom of the inclined top plate 3, the motor 8 can be started to drive the threaded rod 7 to rotate, and then drive the fixed block 5 to move forward and backward, and the inclined top plates 3 on both sides are driven to adjust their front-to-back positions through the smooth through-rod 4 to match the positions of the buckle positions on the plastic product. In the process of demolding and ejecting the plastic product, it is only necessary to start the cylinder 11 to push the rectangular frame 1 up, drive the gear 15 to rotate through the rack 16, and then rotate the bidirectional screw 13. The relatively close sliding plates 2 control the two inclined top plates 3 to be relatively close, and detach them from the buckle positions of the plastic product, thereby achieving the effect of quickly demolding and ejecting the plastic product and improving work efficiency.

[0027] Through the above steps, when there is a front-to-back deviation between the two symmetrical buckle positions on the placed plastic product and the bottom of the inclined top plate 3, the motor 8 can be started to drive the threaded rod 7 to rotate, and then drive the fixed block 5 to move forward and backward, and the inclined top plates 3 on both sides are driven by the smooth through rod 4 to adjust the front-to-back positions to correspond to the positions of the buckle positions on the plastic product. The device can correspond to the use of plastic products with different buckle positions, has strong flexible adjustment capabilities, high versatility, and is easy and convenient to operate, thereby improving work efficiency.
