Abstract

The invention discloses an oblique jacking accelerating core pulling mechanism assembly capable of realizing ultra large-angle down slope. The assembly mainly comprises an oblique jacking head 7, an oblique jacking rod 5, an oblique jacking T-shaped block 4, a guide rod 9, an oblique jacking seat with a slipway 10, an accelerating guide rod 2 for accelerating down slope and a peripheral auxiliary mechanism. Mainly aiming at the defects of a common oblique jacking core pulling mechanism, the core pulling structural form and the core pulling action principle are changed, so that certain potential problems such as insufficient oblique jacking strength, breakage, oblique jacking glue shoveling and the like, the appearance requirement of a product is improved, the performance requirement of the product is met, and the problem of large down-slope inclination angle at the reversely buckled position of the surface of the product in the common oblique jacking core pulling structure is solved.

Description

technical field [0001] The invention relates to a core-pulling mechanism assembly of an injection mold, and more specifically, to a core-pulling mechanism assembly for a downhill inclined roof acceleration in an injection mold. Background technique [0002] During the design process of injection molds, it is often encountered that there is an undercut inside the plastic product and the product cannot be directly removed from the mold. In this case, in order to achieve the purpose of smooth demoulding under the undercut, it is necessary to use a suitable inclined top core puller mechanism. However, if there is a downward sloping angle of the surface or a protruding product shape on the inside within the stroke range of the undercut core puller, in order to avoid the sloping top shoveling glue and damaging the product, it is necessary to adopt a downhill sloping top structure. Because the strength requirements must be considered for the downhill slope roof, the slope angle of...
