A multi-bar linkage inclined top mold

Abstract

The invention discloses a multi-rod linkage inclined top mold, which comprises: a base base, a support plate and a punch combined base plate, a punch is arranged on the punch combined base, a knockout module is embedded in the punch, the The bottom ends of the first slanting rod and the second slanting rod are respectively hinged on the foundation base, the first sliding block is correspondingly arranged in the first chute track, and the second chute track is arranged on the slope of the first sliding block On the surface, the second sliding block is correspondingly arranged in the second chute track, and the third oblique rod is connected and arranged between the second sliding block and the stripping module. Through the above method, in the multi-bar linkage inclined roof mold of the present invention, the swing of the first inclined bar drives the swing of the first slider and the second inclined bar, causing a chain reaction of the third inclined bar to realize the ejection of the module. Exit and reset to form a super-large-angle inclined roof linkage structure, stable structure, convenient height adjustment of the third inclined rod, good adaptability, and improved demoulding efficiency.

Description

technical field [0001] The invention relates to the field of plastic molds, in particular to a multi-bar linkage inclined top mold. Background technique [0002] Some plastic products can fall off smoothly when the mold is opened, but some plastic products cannot fall off automatically or often cannot fall off automatically due to structural or material problems. Therefore, in order to improve the release effect of plastic products, some molds need to be additionally equipped with corresponding The demoulding device, and the inclined top seat is a commonly used demoulding device. [0003] The structure of the inclined ejector seat of the ordinary mold is simple, the height of the ejector pin cannot be adjusted, the installation is cumbersome, and it is difficult to realize the super large-angle inclined ejector work of the complex mold, the coordination of single ejector pin or multiple ejector pins in the inclined ejector seat is poor, and the operation synchronization is n...
