Double-arc core-pulling structure

Abstract

This utility model discloses a double-arc core-pulling structure, including a slider seat and an arc core-pulling slider connecting block. The arc core-pulling slider connecting block is rotatably connected to a slot in the slider seat. A first arc core-pulling slider is fixedly connected to the arc core-pulling slider connecting block, and a second arc core-pulling slider is fixedly connected to the arc core-pulling slider connecting block. In this utility model, after the upper and lower molds are opened, the slider seat is driven by the hydraulic cylinder body, which drives the first and second arc core-pulling sliders to move. The arc core-pulling sliders slide out of the undercut, and then the product can be removed. By using a single hydraulic cylinder to drive the double-arc core-pulling structure, the purchase cost of the hydraulic cylinder body is reduced. The mold processing is simple and convenient, saving the mold development cycle and reducing processing costs. At the same time, no extra opening action is required, saving mold opening production time and improving product production efficiency. The mold structure is simple, not easily damaged, and easy to maintain and repair, reducing maintenance costs.
