Description

Technical Field

[0001] The utility model relates to the technical field of plastic molds, and specifically, to a plastic mold with a cutting function. Background Art

[0002] A plastic mold is a tool that is matched with a plastic molding machine in the plastic processing industry and gives plastic products a complete configuration and precise dimensions. Due to the variety of plastic varieties and processing methods, and the complexity of the structures of plastic molding machines and plastic products, the types and structures of plastic molds are also diverse.

[0003] The patent specification with the publication number CN207290797U discloses a plastic mold capable of automatically cutting off a pouring port. During pouring, the pouring nozzle is placed above the cutting port. After pouring is completed, the hydraulic cylinder drives the sliding cylinder to move upward. The sliding cylinder slides on the pouring pipeline. The rack on the sliding cylinder drives the second gear to rotate. The second gear drives the third gear to rotate. The third gear drives the first gear to rotate. Under the action of the first gear, the cutting knife moves towards the cutting port. Under the action of the cutting knife, the raw material fluid is cut off. At the same time, the sliding cylinder abuts against the first stop block, and then the sliding cylinder drives the pouring pipeline to move upward, separating the pouring pipeline from the mold. This device can cut off the raw material fluid while taking out the pouring pipeline and seal the pouring port, avoiding waste of resources and facilitating the next-step processing of the product.

[0004] However, it is found in the implementation of the related technology that the above technical solution has the following problems: During the use of the above device, the hydraulic cylinder drives the sliding cylinder to move upward. The sliding cylinder slides on the pouring pipeline. The rack on the sliding cylinder drives the second gear to rotate. The second gear drives the third gear to rotate. The third gear drives the first gear to rotate. Under the action of the first gear, the cutting knife moves towards the cutting port. Under the action of the cutting knife, the raw material fluid is cut off. When the cutting knife cuts the plastic mold, when the cutting knife touches the device, the plane of the device is likely to block the cutting knife, resulting in poor cutting effect of the cutting knife on the plastic mold and easy damage to the cutting knife, reducing the service life of the cutting knife. Therefore, further improvement is needed. Summary of the Utility Model

[0005] The utility model provides a plastic mold with a cutting function, which solves the problem in the related technology that it is not convenient to cut the plastic mold.

[0006] The technical solution of the utility model is as follows:

[0007] A plastic mold with a cutting function, comprising a plastic mold body. A chute is provided on the inner wall of the plastic mold body, and a cutting assembly is arranged on the outer surface of the plastic mold body. The cutting assembly includes U-shaped blocks fixedly connected to the upper ends of both sides of the plastic mold body. A bottom cover is fixedly connected to the lower end of the plastic mold body. A pressing plate is arranged below the U-shaped blocks, and a resisting plate is slidably connected to the lower end of the bottom cover.

[0008] Preferably, a through groove is formed through the center of the upper end of the bottom cover. A first L-shaped block and a second L-shaped block are fixedly connected to the lower end of the bottom cover. The first L-shaped block and the second L-shaped block are located on both sides of the through groove, and the structures of the first L-shaped block and the second L-shaped block are symmetrical.

[0009] Preferably, the through groove is communicated with the chute.

[0010] Preferably, a T-shaped groove is formed in the upper end of the first L-shaped block, and a moving block is slidably connected to one end of the first L-shaped block.

[0011] Preferably, a T-shaped block is fixedly connected to one end of the moving block, a spring is fixedly connected to one side of the moving block, an elastic rope is fixedly connected to the other side of the moving block, and a connecting rod is fixedly connected to the outer surface of the elastic rope.

[0012] Preferably, the T-shaped block is slidably connected to the T-shaped groove. One end of the spring is fixedly connected to one side of the first L-shaped block. The other end of the elastic rope is fixedly connected to one side of the moving block of the second L-shaped block group. One end of the connecting rod is fixedly connected to the lower end of the resisting plate.

[0013] Preferably, a telescopic rod is fixedly connected to the upper end of the pressing plate, a cutting blade is fixedly connected to the lower end of the pressing plate, and an auxiliary block is fixedly connected to the lower end of the cutting blade.

[0014] Preferably, the upper end of the telescopic rod is fixedly connected to the lower side of the U-shaped block. Both sides of the pressing plate are slidably connected to the chute, and the auxiliary block is slidably connected to the chute.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] 1. When the telescopic rod of the present utility model is controlled to extend, the telescopic rod will push the pressing plate to move along the sliding groove. At this time, the auxiliary block will press the abutting plate to move along the sliding groove. As the abutting plate moves downward, the abutting plate will press the elastic rope to move downward accordingly. As the elastic rope moves downward, the relative length of the elastic rope in the vertical direction relatively elongates, and the relative length of the elastic rope in the horizontal direction relatively shortens. As a result, the shortening of the elastic rope in the horizontal direction will pull the moving block to move along the T-shaped groove, that is, the moving block will pull the spring along the T-shaped groove to move closer to the abutting plate. When the upper end of the abutting plate disengages from the through groove, the lower end of the cutting blade will also pass through the through groove. At this time, under the action of the cutting blade, the plastic mold can be effectively cut, solving the problem of inconvenient cutting of the plastic mold.

[0017] 2. When the telescopic rod of the present utility model shortens, the cutting blade will disengage from the through groove and the sliding groove. After the auxiliary block disengages, the pressure on the elastic rope disappears, and at the same time, the force exerted by the elastic rope on the moving block disappears, that is, the pulling force on the spring disappears. At this time, the spring will generate an opposite force causing the spring to return to its initial state, that is, the spring will pull the moving block to move along the T-shaped groove until the elastic rope returns to the horizontal balance state. At this time, the restoration of the initial state of the spring can be completed. At the same time, under the action of the connecting rod, the abutting plate re-enters the sliding groove and the through groove. At this time, the upper end of the abutting plate can be made flush with the upper end of the bottom cover, and the side wall of the abutting plate can be made flush with the inner wall of the plastic mold body.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0028] As Figure 1 and Figure 2 shown, this embodiment proposes a plastic mold with a cutting function, including a plastic mold body 1. A slide groove 11 is opened on the inner wall of the plastic mold body 1. A cutting component 2 is arranged on the outer surface of the plastic mold body 1. The cutting component 2 includes a U-shaped block 21 fixedly connected to the upper ends of both sides of the plastic mold body 1. A bottom cover 22 is fixedly connected to the lower end of the plastic mold body 1. A pressing plate 23 is arranged below the U-shaped block 21. A bracing plate 24 is slidably connected to the lower end of the bottom cover 22.

[0029] As Figure 3 shown, a through groove 221 is penetrated and opened at the central position of the upper end of the bottom cover 22. The through groove 221 is communicated with the slide groove 11. The communication between the through groove 221 and the slide groove 11 facilitates the bracing plate 24 to freely move along the slide groove 11, and the through groove 221 will not form an obstruction to the bracing plate 24.

[0030] As Figure 4As shown, a first L-shaped block 222 and a second L-shaped block 223 are fixedly connected to the lower end of the bottom cover 22. The first L-shaped block 222 and the second L-shaped block 223 are located on both sides of the through groove 221. The structures of the first L-shaped block 222 and the second L-shaped block 223 are symmetrical. A T-shaped groove 2221 is formed in the upper end of the first L-shaped block 222. One end of the first L-shaped block 222 is slidably connected to a moving block 2222. On the other side of the moving block 2222, an elastic rope 22223 is fixedly connected. A connecting rod 22224 is fixedly connected to the outer surface of the elastic rope 22223. The T-shaped block 22221 is slidably connected to the T-shaped groove 2221. One end of the spring 22222 is fixedly connected to one side of the first L-shaped block 222. The other end of the elastic rope 22223 is fixedly connected to one side of the moving block 2222 of the second L-shaped block 223 group. The elastic rope 22223 is used to block the pressing plate 24 to prevent the pressing plate 24 from detaching from the overall device, and the elastic rope 22223 is used to drive the moving blocks 2222 on both sides to approach the elastic rope 22223.

[0031] As Figure 5 shown, a T-shaped block 22221 is fixedly connected to one end of the moving block 2222. A spring 22222 is fixedly connected to one side of the moving block 2222. The spring 22222 is used to pull the moving block 2222 away from the elastic rope 22223.

[0032] As Figure 6 shown, a telescopic rod 231 is fixedly connected to the upper end of the pressing plate 23. A cutting blade 232 is fixedly connected to the lower end of the pressing plate 23. An auxiliary block 233 is fixedly connected to the lower end of the cutting blade 232. The upper end of the telescopic rod 231 is fixedly connected to the lower side of the U-shaped block 21. Both sides of the pressing plate 23 are slidably connected to the sliding groove 11. The auxiliary block 233 is slidably connected to the sliding groove 11. The cutting blade 232 is used to cut and divide the plastic mold, and the auxiliary block 233 is used to protect the lower end of the cutting blade 232 to prevent the lower end of the cutting blade 232 from directly hitting the pressing plate 24.

[0033] As Figure 7 shown, one end of the connecting rod 22224 is fixedly connected to the lower end of the pressing plate 24. The connecting rod 22224 is used to form an integral body between the pressing plate 24 and the elastic rope 22223.

[0034] The working principle and usage instructions of the present utility model are as follows: When it is necessary to cut a plastic mold, first, the staff needs to take out the plastic mold body 1, and then the staff needs to extend the control telescopic rod 231. At this time, the telescopic rod 231 will push the pressing plate 23 to move along the sliding groove 11. At this time, the auxiliary block 233 will press the abutting plate 24 to move along the sliding groove 11. As the abutting plate 24 moves downward, the abutting plate 24 will press the elastic rope 22223 to move downward accordingly. As the elastic rope 22223 moves downward, the relative length of the elastic rope 22223 in the vertical direction is relatively elongated, and the relative length of the elastic rope 22223 in the horizontal direction is relatively shortened. As a result, the shortening of the elastic rope 22223 in the horizontal direction will pull the moving block 2222 to move along the T-shaped groove 2221, that is, the moving block 2222 will pull the spring 22222 along the T-shaped groove 2221 to move closer to the direction of the abutting plate 24. When the upper end of the abutting plate 24 disengages from the through groove 221, the lower end of the cutting blade 232 will also pass through the through groove 221. At this time, the plastic mold can be effectively cut under the action of the cutting blade 232. After the plastic mold is cut, the telescopic rod 231 shortens. At this time, the cutting blade 232 will disengage from the through groove 221 and the sliding groove 11. After the auxiliary block 233 disengages, the pressure on the elastic rope 22223 disappears, and at the same time, the force exerted by the elastic rope 22223 on the moving block 2222 disappears, that is, the pressure on the spring 22222 disappears. At this time, the spring 22222 will generate an opposite force, that is, the restoring force causes the spring 22222 to return to its initial state, that is, the spring 22222 will pull the moving block 2222 to move along the T-shaped groove 2221 until the elastic rope 22223 returns to the horizontal balance state. At this time, the restoration of the initial state of the spring 22222 can be completed. At the same time, under the action of the connecting rod 22224, the abutting plate 24 re-enters the sliding groove 11 and the through groove 221. At this time, the upper end of the abutting plate 24 can be made flush with the upper end of the bottom cover 22, and at the same time, the side wall of the abutting plate 24 is flush with the inner wall of the plastic mold body 1.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
