Description
Technical Field
[0001] The utility model relates to the technical field of molds, in particular to a mold for an inner-ring type snap-in vehicle bearing protection dust cover. Background Technique
[0002] A mold is an important tool for manufacturing formed articles in industrial production and has the title of "the mother of industry". It mainly realizes the processing of the outer shape of an article by changing the physical state of the formed material and is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting, and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, and ceramics. In the mold processing industry, for soft rubber products with a long cylindrical shape with inner and outer concave whole circles, since there cannot be obvious gate marks and flash, at least four cavities need to be made for a large quantity. According to the traditional processing method, the product is placed flat and side-gated, and then secondary lifter core pulling is performed. The complex core-pulling structure and small space of the mold will cause poor mold strength, and side gating will cause obvious gate marks on the product and the risk of uneven material flow. Content of the Utility Model
[0003] The purpose of the utility model is to provide a mold for an inner-ring type snap-in vehicle bearing protection dust cover to solve the problems raised in the above background technique, that is, for soft rubber products with a long cylindrical shape with inner and outer concave whole circles, since there cannot be obvious gate marks and flash, at least four cavities need to be made for a large quantity. According to the traditional processing method, the product is placed flat and side-gated, and then secondary lifter core pulling is performed. The complex core-pulling structure and small space of the mold will cause poor mold strength, and side gating will cause obvious gate marks on the product and the risk of uneven material flow.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A mold for an inner-ring type snap-in vehicle bearing protection dust cover, comprising:
[0005] A first mold base;
[0006] A rear mold core, which is arranged inside the first mold base;
[0007] Rear mold inserts, which are arranged equidistantly on the top of the rear mold core;
[0008] Side sliders, which are symmetrically arranged on both sides of the rear mold core, and the inner sides of the side sliders are matched with the rear mold inserts;
[0009] A second mold base, which is matched with the first mold base;
[0010] A front mold core, which is arranged inside the second mold base;
[0011] A hot runner gating part, which is arranged inside the front mold core;
[0012] Cold runner gating parts, which are arranged equidistantly at the bottom of the front hot runner gating part.
[0013] As a preferred embodiment of the present utility model: it further includes a front mold elastic insert, and the front mold elastic insert is arranged at the bottom of the cold runner glue inlet part.
[0014] As a preferred embodiment of the present utility model: it further includes a slider insert, and the slider inserts are symmetrically and equidistantly arranged inside the side slider.
[0015] As a preferred embodiment of the present utility model: it further includes a product, and the product is placed outside the rear mold insert.
[0016] As a preferred embodiment of the present utility model: a plurality of second cooling water holes are opened inside the front mold core, and a plurality of third cooling water holes are opened inside the rear mold core.
[0017] As a preferred embodiment of the present utility model: a plurality of first cooling water holes are opened inside the side slider.
[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: by arranging the product in a four-cavity vertical layout, the outer ring snap fits are made into left and right large sliders, the inner ring snap fits are split in half and made into front mold elastic blocks for forced demolding, and a full-circle disc-shaped glue inlet is made. (The product is made of TPE soft glue). When the mold is opened, the front mold elastic blocks are first taken out and then forced to pull off the snap fits. Then, the rear mold is controlled to blow air to assist the product to separate from the rear mold, ensuring that the mold strength is guaranteed, the processing amount is simplified, the injection molding production is smooth, and the cost is saved without affecting the product structure and appearance, and the mold processing cycle is controlled within the specified time to meet the requirements of customers; through the structural application of making the outer ring snap fits into left and right large sliders, splitting the inner ring snap fits in half and making the front mold elastic blocks for forced demolding and a full-circle disc-shaped glue inlet (the TPE soft glue characteristics allow for full-circle forced demolding), the integrity of the overall product structure and appearance requirements are ensured. At the same time, various risks and extended delivery times caused by side glue inlet and secondary lifter core pulling in ordinary production molds are avoided, and the value of rapid molds in normal production and manufacturing is realized.
