Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, specifically a plastic mold with trimming function. Background Technology

[0002] In modern industrial production, plastic products are widely used in many fields such as electronics, automobiles, medical devices, and daily necessities due to their advantages such as light weight, corrosion resistance, and low cost. As a key tool for molding plastic products, the performance and quality of plastic molds directly affect the production efficiency and quality of plastic products.

[0003] Currently, common plastic mold trimming technologies on the market often have some problems. The trimming efficiency is low, and traditional trimming equipment cannot achieve fast and continuous trimming operations, which leads to a longer production cycle and increased production costs for plastic products. The trimming accuracy is difficult to guarantee. Due to the lack of precise guiding and adjustment mechanisms, the trimming cutter is prone to deviation during operation, making it impossible to accurately remove excess parts from the edges of plastic parts, resulting in large product size errors and making it difficult to meet the production requirements of high-precision products.

[0004] In view of this, we propose a plastic mold with trimming function. Utility Model Content

[0005] The purpose of this invention is to provide a plastic mold with a trimming function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plastic mold with a trimming function includes a fixed mold, a bracket fixedly mounted on the side wall of the fixed mold, the outer wall of the bracket being slidably mounted inside a movable mold, and a trimming mechanism provided on the fixed mold, the trimming mechanism comprising:

[0008] A slide rail is fixedly installed on the inner wall of the fixed mold. A slider is slidably installed inside the slide rail. A rectangular block is fixedly installed on the outer wall of the slider. The side wall of the rectangular block slidably fits against the inner side wall of the fixed mold.

[0009] An asynchronous motor is fixedly installed on the side wall of the fixed mold. A first threaded rod is fixedly installed on the output end of the asynchronous motor. The two ends of the first threaded rod are rotatably installed on the inner walls of the two ends of the fixed mold through bearing components. The outer wall of the first threaded rod is threaded into the inside of the rectangular block. A groove is opened on the side wall of the rectangular block. The inner wall of the groove is fixedly installed on one end of the spring rod.

[0010] A rectangular frame is fixedly installed at the other end of the spring rod. A motor is fixedly installed on the inner wall of the rectangular frame. A second threaded rod is fixedly installed at the output end of the motor. The two ends of the second threaded rod are rotatably installed on the inner walls of the two ends of the rectangular frame through bearing components. The outer wall of the second threaded rod is threaded into the interior of the movable block. A blade is fixedly installed on the side wall of the movable block. The inclined surface of the blade slides against the side wall of the fixed mold.

[0011] In a further embodiment, two sets of slide rails and sliders are provided.

[0012] In a further embodiment, the blades are provided in two sets, resulting in a better trimming effect.

[0013] In a further embodiment, the bracket is provided in multiple sets.

[0014] In a further embodiment, the fixed mold is provided with an auxiliary mechanism, which includes an annular air pipe. The annular air pipe is fixedly installed on the outer wall of the fixed mold. A dust outlet is opened on the side wall of the annular air pipe, and the dust outlet is connected to a dust collection device. An L-shaped pipe is fixedly installed inside the fixed mold, and a through hole is opened in the side wall of the annular air pipe at the position corresponding to the L-shaped pipe.

[0015] In a further embodiment, the annular air pipe, the dust outlet, and the L-shaped pipe are internally connected.

[0016] In a further embodiment, multiple sets of the L-shaped tubes are provided.

[0017] Compared with the prior art, this utility model provides a plastic mold with trimming function, which has the following beneficial effects:

[0018] 1. This plastic mold with trimming function improves trimming efficiency and quality by setting up a trimming mechanism. An asynchronous motor drives the first threaded rod to rotate, and a rectangular block that engages with the threaded rod moves linearly along the inner wall of the fixed mold with the assistance of a slide rail and a slider. At the same time, a rectangular frame connected by a spring rod can adapt to certain positional changes. The motor drives the second threaded rod to make the movable block drive the blade to slide along the side wall of the fixed mold. The inclined surface of the blade is in contact with the side wall of the fixed mold. The two sets of blades work simultaneously, and with the support of the bracket for sliding support of the movable mold, efficient and precise trimming of plastic parts is achieved, thereby improving the trimming effect.

[0019] 2. This plastic mold with trimming function has an auxiliary mechanism to clean up the debris generated during the trimming process. After the trimming work is completed, the dust outlet of the annular air pipe is connected to a dust collection device. The air inside the annular air pipe is sucked out through the dust outlet, and the debris generated during trimming is quickly sucked out of the mold through the L-shaped pipe. This maintains a clean environment inside the mold and prevents debris residue from affecting the molding quality of subsequent plastic parts and the normal operation of the mold.

[0033] Please see Figures 1-7 This utility model provides a technical solution:

[0034] A plastic mold with trimming function includes a fixed mold 1, a bracket 2 fixedly installed on the side wall of the fixed mold 1, multiple sets of brackets 2 are provided, and the outer wall of the bracket 2 is slidably installed inside the movable mold 3.

[0035] In one embodiment of this utility model, a trimming mechanism 4 is provided on the fixed mold 1. The trimming mechanism 4 includes a slide rail 41. The slide rail 41 is fixedly installed on the inner wall of the fixed mold 1. A slider 42 is slidably installed inside the slide rail 41. Two sets of slide rails 41 and sliders 42 are provided. A rectangular block 43 is fixedly installed on the outer wall of the slider 42. The side wall of the rectangular block 43 slides against the inner side wall of the fixed mold 1. An asynchronous motor 44 is fixedly installed on the side wall of the fixed mold 1. A first threaded rod 45 is fixedly installed at the output end of the asynchronous motor 44. The two ends of the first threaded rod 45 are rotatably installed on the inner walls of both ends of the fixed mold 1 through bearing components. The outer wall of the first threaded rod 45 is threadedly engaged with the rectangular block 43. Inside the rectangular block 43, a groove 46 is provided on the side wall of the rectangular block 43. The inner wall of the groove 46 is fixedly installed on one end of the spring rod 47. A rectangular frame 48 is fixedly installed on the other end of the spring rod 47. A motor 49 is fixedly installed on the inner wall of the rectangular frame 48. A second threaded rod 410 is fixedly installed on the output end of the motor 49. The two ends of the second threaded rod 410 are rotatably installed on the inner walls of the two ends of the rectangular frame 48 through bearing components. The outer wall of the second threaded rod 410 is threadedly engaged with the inside of the movable block 411. A blade 412 is fixedly installed on the side wall of the movable block 411. Two sets of blades 412 are provided to improve the trimming effect. The inclined surface of the blade 412 slides against the side wall of the fixed mold 1.

[0036] In this embodiment, before the plastic mold starts working, the plastic part to be trimmed is placed in a suitable position between the fixed mold 1 and the movable mold 3. The bracket 2, with its multiple sets of stable support structures, ensures that the movable mold 3 can slide smoothly along the outer wall of the bracket 2, thereby realizing the opening and closing action of the mold and completing the placement and initial fixation of the plastic part. When it is necessary to trim the plastic part, the trimming mechanism 4 is activated, the asynchronous motor 44 starts, and its output end drives the first threaded rod 45 to rotate. Since the first threaded rod 45 and the internal threads of the rectangular block 43 mesh with each other, under the constraint of the sliding guide structure formed by the slider 42 and the slide rail 41, the rectangular block 43 will make a precise linear movement along the inner wall of the fixed mold 1. During this process, the spring rod 47 installed in the groove 46 on the side wall of the rectangular block 43 gives the connected rectangular frame 48 a certain elastic movement space, so that it can flexibly adapt to the plastic part. In case of potential dimensional deviations or surface unevenness, the motor 49 also starts working, and its output drives the second threaded rod 410 to rotate. The second threaded rod 410 engages with the internal thread of the movable block 411, causing the movable block 411 to drive the blade 412 to slide along the side wall of the fixed mold 1. The inclined surfaces of the two sets of blades 412 precisely fit against the side wall of the fixed mold 1. When the rectangular block 43 moves in a straight line, the blade 412 will cut and trim the excess part of the edge of the plastic part with a stable cutting angle and pressure. The force generated by the blade 412 during the cutting process will be transmitted to the rectangular frame 48 through the movable block 411 and the second threaded rod 410. The spring rod 47 can effectively buffer and offset some of the vibration and impact caused by the cutting force through its own elastic deformation, ensuring that the blade 412 always maintains a stable cutting state and achieves efficient and precise trimming of the plastic part.

[0037] In one embodiment of this utility model, an auxiliary mechanism 5 is provided on the fixed mold 1. The auxiliary mechanism 5 includes an annular air pipe 51. The annular air pipe 51 is fixedly installed on the outer wall of the fixed mold 1. A dust outlet 52 is opened on the side wall of the annular air pipe 51. The dust outlet 52 is connected to a dust collection device. An L-shaped tube 53 is fixedly installed inside the fixed mold 1. A through hole is opened at the corresponding position of the L-shaped tube 53 on the side wall of the annular air pipe 51. The annular air pipe 51, the dust outlet 52 and the L-shaped tube 53 are internally connected. Nine sets of L-shaped tubes 53 are provided.

[0038] In this embodiment, after the trimming work is completed, in order to clean up the debris generated during the trimming process, the auxiliary mechanism 5 is activated, and the dust outlet 52 of the annular air pipe 51 is connected to a dust collection device. The air inside the annular air pipe 51 is sucked out through the dust outlet 52, and the debris generated during trimming is quickly sucked out of the mold through the L-shaped pipe 53, thereby maintaining a clean environment inside the mold and avoiding debris residue from affecting the molding quality of subsequent plastic parts and the normal operation of the mold.
