Abstract
Description
Technical Field
[0001] The utility model relates to the field of injection molds, and particularly relates to a double-slider motion structure and a mold which are convenient to place. Background Technique
[0002] Many injection products are composite products. For example, a large part is made of plastic material, and a small part is made of metal material, such as metal bushings, screw sleeves, and the like. When processing such products, these bushings and screw sleeves need to be placed at appropriate positions in the injection mold and then the mold is closed for injection molding.
[0003] The common operation steps of the prior art are as follows: Step 1, the mold is opened and the slider is opened; Step 2, the product is taken out; Step 3, the bushing is manually placed on the slider; Step 4, the mold is closed and the slider is pushed at the same time; Step 5, injection molding is carried out; Step 6, after inspection and being correct, it is put into storage. Since the bushing buried in the injection product is below the mold parting surface and the mold space is limited, it is difficult to place manually. When the mold is closed, due to insufficient stability, the bushing is likely to fall into the mold, which will cause damage to the mold and increase the mold repair cost.
