Mesh insert pin core-pulling induction die structure

Abstract

The invention discloses a mesh insert pin core-pulling induction die structure. The structure comprises a lower die core, a sliding block, an insert pin fixing plate, an insert pin, a connecting rod,a sensor and a sensing oil cylinder, wherein the sliding block and the side of the lower die core are in corresponding butt joint to form a cavity; the insert pin fixing plate is movably arranged on the top of the sliding block, the insert pin is connected to the insert pin fixing plate and penetrates through the sliding block to extend into the cavity, the connecting rod synchronously moves relative to the insert pin, the sensor corresponds to the tail end of the connecting rod, and the sensing oil cylinder is arranged on the side of the sliding block and drives the sliding block to retreat from the cavity. The sensor transmits a moving signal of the connecting rod to the sensing oil cylinder through an injection molding machine. According to the structure, the time when the sliding blockretreats is accurately controlled, and forming of a mold opening product is precisely controlled.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a mesh-studded needle core-pulling induction mold structure. Background technique [0002] For appearance products, the surface needs to be scratched. For the deep hole structure on the side wall, it is necessary to use the insert pin to penetrate the deep hole position, and use the slider to exit the side wall position. In the existing slider structure, the inclined guide post is used to delay the mold opening, and wait until the insert position is completely withdrawn. Only when the slider is separated can the slider be separated; it is impossible to detect whether the insert is completely pulled out in place during the whole production of this structure, and the wrong time for the slider to withdraw will cause the product to be strained. This structure relies on high-precision parts matching. When the matching accuracy of products or parts is not in place, the push...

For the deep hole structure on the side wall, it is necessary to use the insert pin to penetrate the deep hole position, and use the slider to exit the side wall position. In the existing slider structure, the inclined guide post is used to delay the mold opening, and wait until the insert position is completely withdrawn. , the slider can be separated; this structure cannot detect whether the insert is completely pulled out in place during the whole production process, and the wrong time for the slider to withdraw will cause product strain

This structure relies on high-precision parts matching. When the matching accuracy of products or parts is not in place, the push-out time of the slider cannot be controlled, resulting in defective products
