Description

Technical Field

[0001] The invention relates to the technical field of automobile sealing component processing equipment, and in particular to a step-by-step feeding mechanism in an injection mold. Background Art

[0002] The use process of injection molds usually includes loading, injection molding, and unloading. We usually call the process of inserting the seal into the mold loading. The length of the loading time and the completeness of the seal's appearance after loading have a relatively large impact on the injection molding cycle time and the overall appearance after injection molding. There are currently two ways of loading: one is manual loading, that is, the worker inserts the seal into the mold with both hands; the other is auxiliary loading, that is, the worker manually puts the seal on the auxiliary device, and then sends it into the mold through the auxiliary device. Some seals have a relatively complex cross-section, which leads to greater friction during loading, and manual loading is very difficult. If too much force is used, the seal will bend and deform, destroying the appearance of the final product and affecting the loading effect.

[0003] The existing auxiliary feeding method for seals with complex cross-sections is to place the seal on a plug plate fixed to an external auxiliary mechanism, fix the seal by reverse teeth, and then push it into the mold manually or automatically. This method has the following shortcomings:

[0004] 1. When loading manually, the resistance gradually increases as the loading progresses, and the workers have to work very hard;

[0005] 2. During automatic feeding, the multiple lips at the end of the seal are difficult to align accurately with the mold, which can easily lead to extrusion and deformation of the seal, resulting in unnecessary waste;

[0006] 3. When feeding, the teeth are prone to move with the seal, resulting in inaccurate final feeding position;

[0007] 4. The seal is always fixed on the plug plate during the injection molding process, which makes it inconvenient for the loading mechanism to move back or flip over to unload after loading. Summary of the invention

[0008] The present invention aims to solve the deficiencies of the prior art and provides a step-by-step feeding mechanism in an injection mold.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions:

[0013] The positioning and clamping mechanism is used to position and clamp the seal when loading. The positioning and clamping mechanism includes a positioning arm and a clamping device. The positioning arm is movably connected to the support plate. The clamping device includes an inserting plate for inserting into the seal slot. The inserting plate is fixedly connected to the sliding plate. A clamp is provided on one side of the inserting plate.

[0014] The lifting plate is used to lift the seal from the plug plate after feeding. One end of the lifting plate is hinged to the sliding plate. The lifting plate is provided with a strip hole for the plug plate to pass through.

[0027] 2. The first half of the loading process is done manually, which ensures that the multiple lips at the end of the seal are accurately aligned with the mold, effectively preventing the seal from being squeezed and deformed;

[0028] 3. The second half of the feeding process uses a mechanical push mechanism to push the material in, which effectively solves the problem of laborious feeding in the second half and reduces the labor intensity of workers;
