Crossed secondary core pulling mold

Abstract

The invention relates to the technical field of molds, and discloses a crossed secondary core pulling mold which comprises a movable mold, a fixed mold and core pulling assemblies. The movable mold and the fixed mold are oppositely arranged to form a forming cavity. Each core pulling assembly comprises a driving device, a sliding base, a first core pulling unit and a second core pulling unit, wherein an output shaft of the driving device is connected with the sliding base, the first core pulling unit comprises a first sliding core and a vertically-arranged sliding block, the second core pulling unit comprises a sliding core fixing plate and a second sliding core, the sliding core fixing plate is located on the side edge, close to the forming cavity, of the sliding base, one end of the first sliding core movably penetrates through the sliding core fixing plate and is connected with the sliding base, an obliquely-upward jacking plate is fixed to the other end of the first sliding core, the sliding block is slidably with the jacking plate, the second sliding core is fixed to the side face, away from the sliding base, of the sliding core fixing plate, and the sliding core fixing plate is movably connected with the sliding base in a blocking mode. According to the crossed secondary core pulling mold, vertical and horizontal core pulling actions can be completed in sequence through one core pulling assembly, the core pulling structure is simplified, and the mold opening cost is reduced.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a cross-type secondary core-pulling mold. Background technique [0002] At present, the scope of mold application is becoming wider and wider, and people's requirements for mold production technology are getting higher and higher. There are many ways to realize mold processing, and the application range of core-pulling mold processing methods is also becoming wider and wider. Plastic products of various shapes can be easily and quickly prepared by injection molding. When it is necessary to produce a product with holes in both the X direction and the Y direction, the most commonly used method when designing this kind of mold is to pull it through the template in one direction. Core-pulling, the other direction drives the core-pulling through the oil cylinder. The core-pulling settings in the two directions involve more parts, which will inevitably lead to a larger mold volume and in...
