Problems solved by technology

The positioning structure of the insert in the mold is crucial, which not only affects the feasibility and convenience of the mold operation, but also affects the quality and performance of the product, and can even directly lead to the scrapping of the product
Larger tubular inserts are characterized by large volume and heavy weight. It is very difficult to position on the mold, and it is easy to scratch and leak materials, which makes it difficult to guarantee product quality.

Abstract

The invention discloses an insert positioning structure in a die. The insert positioning structure comprises a bushing and a seal block, the bushing is fixedly connected with the seal block, and the seal block is fixedly connected with the body of the die; at least one positioning slot along the circumference direction of the bushing is arranged in the bushing, and a first polytetrafluoroethylene protection sleeve is arranged in the positioning slot; and a second polytetrafluoroethylene protection sleeve is arranged in the seal block. The insert positioning structure in the die realizes the convenience of the installation and positioning of the insert, and can prevent material leakage.

Description

technical field [0001] The invention relates to the positioning of mold inserts in the APG process, in particular to an insert positioning structure in a mold. Background technique [0002] The APG process refers to the epoxy resin automatic pressure gel process, that is, the process of heating the epoxy resin to make it thermoset. [0003] At present, the insulation parts of medium and high voltage electrical equipment are generally processed by APG process. In order to increase the product strength, metal parts are usually embedded in the injection molding process. The positioning structure of the insert in the mold is crucial, which not only affects the feasibility and convenience of mold operation, but also affects the quality and performance of the product, and can even directly lead to the scrapping of the product. Larger tubular inserts are characterized by large volume and heavy weight. It is very difficult to position on the mold, and it is easy to scratch and leak...
