Problems solved by technology

[0002] Plastic products are widely used in daily life. With the continuous improvement of demand, pure plastic products cannot meet the needs of industry and life. A large number of plastic products need to be embedded with precision inserts to meet the special needs of product assembly. Ordinary inserts are usually Placed directly in the cavity, it is difficult to install precision inserts, especially small package inserts, with low precision by traditional methods

Abstract

The invention discloses a mold provided with a mechanism for directly pushing out a slider insert through an ejector retainer plate, and belongs to the field of thermoplastic plastic forming molds. The problems existing in a mold for a plastic product with a plurality of precision inserts needing to be installed therein are solved through the mold. Precise positioning of the slider insert 6 and a slider body 5 is realized through precise matching between a groove in the slider insert 6 and a boss on the slider body 5. The requirements for sliding stability and precision of the slider insert 6 are guaranteed through the cooperative use of a guide platform on the slider insert 6 and a guide groove in a slider seat 7. Due to application of the mechanism, the structure of the mold is simplified, the space of the mold is effectively used, an operator can install precise inserts conveniently, the production efficiency is improved, and the reject ratio of products is lowered.

Description

technical field [0001] The invention belongs to the field of molding molds for thermoplastic plastics, and relates to a mold provided with a needle plate to directly push out a slide block insert mechanism, which is mainly applied to the molding mold of plastic products with precision inserts. Background technique [0002] Plastic products are widely used in daily life. With the continuous improvement of demand, pure plastic products cannot meet the needs of industry and life. A large number of plastic products need to be embedded with precision inserts to meet the special needs of product assembly. Ordinary inserts are usually Placed directly in the cavity, it is difficult to install precision inserts, especially small set inserts, with low precision by traditional methods. Contents of the invention [0003] The object of the present invention is to provide a mold with a mechanism for directly pushing out the slider insert by the needle plate, which realizes the ejection ...
