Rocker arm core-pulling arc structure of bathroom product mold

Abstract

The invention discloses a bathroom product mold rocker arm core-pulling arc structure which comprises a support and further comprises a rocker arm, a connecting rod, a push block, a core-pulling sliding block guide seat and a driving device used for driving the push block to do reciprocating motion along a straight line. One end of the connecting rod is hinged to the push block, the other end of the connecting rod is hinged to one end of the rocker arm, the other end of the rocker arm is hinged to the support, and a core-pulling sliding block is arranged on the rocker arm; the core-pulling sliding block is provided with a first arc-shaped concave surface, the core-pulling sliding block guide seat is correspondingly provided with a first arc-shaped convex surface, and the first arc-shaped convex surface is matched with the first arc-shaped concave surface in shape. The rocker arm core-pulling arc structure of the bathroom product mold is small in installation space, easy to assemble and maintain and high in motion precision.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a core-pulling arc structure of a rocker arm of a bathroom product mold. Background technique [0002] Core pulling is an important technical solution in mold design. In actual production, product shapes are different, especially for arc-shaped products, the core pulling technology requirements are higher. In the traditional scheme, the core is moved according to the arc path by means of gear transmission, so as to realize the core pulling. However, such a scheme has the following shortcomings: (1) poor stability, once the gear is stuck, it cannot work normally; (2) the coordination difficulty is high, and the maintenance is very unchanged; (3) the installation space is large. Therefore, it is necessary to propose a new technical solution with simple structure, easy assembly, and easy core pulling. [0003] It can be seen that the existing technology still needs to be improved a...
