Description

Technical Field

[0001] This utility model relates to the field of plastic worm gear technology, specifically to a plastic worm gear injection mold that can be flexibly adjusted. Background Technology

[0002] Injection molding of plastic worm gears is a process in which thermoplastic or thermosetting plastic is injected into a mold under high pressure, and after cooling and solidification, it forms a part of a specific shape. In order to facilitate removal of the part, the injection mold of plastic worm gears is generally a combination mold, which is formed by combining upper and lower molds. After processing, the upper and lower molds are separated, and finally the worm gear is demolded from the mold.

[0003] The prior art document, "A Flexible Adjustable Plastic Worm Gear Injection Mold," (CN221913069U), utilizes a moving mechanism and an ejector mechanism to switch between different injection mold shells and combinations with the lower and upper mold bases within a mold assembly. The mold assembly contains multiple injection mold shells. Based on the size of the plastic worm gear being processed, the appropriate injection mold shell is selected. A moving component controls the synchronous movement of the mold assembly within the upper and lower mold bases, aligning the corresponding injection mold shell with a rectangular limiting groove. The ejector mechanism then pushes the injection mold shell into the rectangular limiting groove, completing the adjustment of the injection mold shells in the upper and lower mold bases. This allows for the processing of multiple sizes and models of plastic worm gears within a single injection mold, demonstrating strong adjustability and high adaptability.

[0004] However, injection molds cannot flexibly adjust the size of the product during use. When it is necessary to change the product, the entire mold set often needs to be replaced, which causes inconvenience to users and can no longer meet their needs. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexibly adjustable plastic worm gear injection mold, comprising an upper module and a lower module. The top of the lower module has a groove, and a sleeve module is disposed inside the groove. The sleeve module has a cavity inside, and an adjustment module is fixedly disposed inside the sleeve module. Guide blocks are fixedly disposed on both sides of the adjustment module. Lead screws are movably disposed on both sides of the bottom of the sleeve module. A collar is fixedly disposed near the top of the front surface of the sleeve module, and a limit rod is disposed inside the collar. A limit groove is formed on the front surface of the adjustment module.

[0007] Furthermore, the upper module and the lower module are in contact with each other, and mounting plates are fixedly installed on the opposite sides of the upper module and the lower module.

[0008] Furthermore, the number of adjustment modules is four, and the four adjustment modules are designed to be equidistant from each other. The top of each adjustment module is provided with a forming groove, and the size of the forming groove is different for each module.

[0009] Furthermore, the top of the lead screw passes through the sleeve module and the guide block in sequence and extends to the outside of the guide block, and the lead screw is threadedly connected to the guide block.

[0010] Furthermore, the limiting groove and the adjustment module are integrated into one design, and the limiting groove and the limiting rod are compatible.

[0011] Furthermore, the front end of the limiting rod passes through the collar and extends to its outside, and the limiting rod is fixedly connected to the collar by a spring.

[0012] Furthermore, the rear end of the limiting rod passes through the sleeve module and extends into the interior of the limiting groove, and the limiting rod engages with the limiting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This flexibly adjustable plastic worm gear injection mold, through the setting of sleeve modules, adjustment modules, lead screws and limit rods, enables the device to quickly complete the conversion of products of various sizes according to production needs, saving users time, bringing convenience, improving the practicality of the device, and meeting the user's needs.

[0016] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not limiting of the scope of protection of this utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a flexibly adjustable plastic worm gear injection mold, including an upper module 1 and a lower module 2. The upper module 1 and the lower module 2 cooperate with each other to perform injection molding. The top of the lower module 2 has a groove 3, which is used to set corresponding components. The groove 3 has a sleeve module 4 inside, which is used to set an adjustment module 5. The sleeve module 4 has a cavity inside, and the adjustment module 5 is fixedly set inside the sleeve module 4 for adjustment. Guide blocks 6 are fixedly set on both sides of the adjustment module 5, which can play a guiding role. Screws 7 are movably set on both sides of the bottom of the sleeve module 4, which can drive the guide blocks 6 to move. A collar 8 is fixedly set on the top of the front surface of the sleeve module 4, which is used to set corresponding components. The collar 8 has a limit rod 9 inside, which can limit the movement. The front surface of the adjustment module 5 has a limit groove 10, which is used to cooperate with the limit rod 9.

[0018] Furthermore, the upper module 1 and the lower module 2 are in contact with each other, and a mounting plate 11 is fixedly provided on the opposite side of the upper module 1 and the lower module 2. The mounting plate 11 facilitates the user to install the upper module 1 and the lower module 2.

[0019] Furthermore, the number of adjustment modules 5 is four, and the four adjustment modules 5 are designed to be equidistant from each other. The top of the adjustment module 5 is provided with a forming groove, and the size of the forming groove is different. The forming groove adopts a different size design, which can be used to produce products of various sizes.

[0020] Furthermore, the top of the lead screw 7 passes through the sleeve module 4 and the guide block 6 in sequence and extends to the outside of the guide block 6. The lead screw 7 is threadedly connected to the guide block 6, and the lead screw 7 can drive the guide block 6 to move.

[0021] Furthermore, the limiting groove 10 and the adjustment module 5 are integrated into one design, and the limiting groove 10 and the limiting rod 9 are compatible. The limiting groove 10 is used to cooperate with the limiting rod 9.

[0022] Furthermore, the front end of the limiting rod 9 passes through the collar 8 and extends to its outside. The limiting rod 9 is fixedly connected to the collar 8 by a spring. This design enables the limiting rod 9 to be connected.

[0023] Furthermore, the rear end of the limiting rod 9 passes through the sleeve module 4 and extends into the interior of the limiting groove 10. The limiting rod 9 is engaged with the limiting groove 10, and the limiting rod 9 can play a limiting role.

[0024] Working principle: When using this device, if it is necessary to change the product, the user turns the screw 7 at the bottom of the sleeve module 4 to rotate and drive the guide block 6 to move. The movement of the guide block 6 drives the adjustment module 5 to move, so that the adjustment module 5 moves out from the lower module 2. In this way, the user selects the appropriate size adjustment module 5 for use. After selection, the user engages the limit rod 9 with the limit groove 10 to limit the device.

[0025] Based on the above work process, we can conclude that: This flexibly adjustable plastic worm gear injection mold, through the setting of sleeve module 4, adjustment module 5, lead screw 7 and limit rod 9, enables the device to quickly complete the conversion of products of various sizes according to production needs, saving time for users, bringing convenience to users, improving the practicality of the device, and meeting the user's needs.
