Plastic mold core pulling mechanism

Abstract

The invention relates to the technical field of plastic molds, in particular to a plastic mold core pulling mechanism. The plastic mold core pulling mechanism comprises a core pulling base. Side plates are fixedly arranged at the top end of the core pulling base and in the positions close to the front side and back side of the base. The front sides of the two side plates are both provided with a plurality of through holes. The tops of the two side plates are both engraved with scale lines. One side of the core pulling base is fixedly connected with a fixed plate. The bottom of the side, far away from the core pulling base, of the fixed plate is fixedly provided with a mounting plate. The upper end face of the core pulling base is provided with a first sliding groove. A core pulling slidingseat is slidably mounted on the first sliding groove. The end, close to the fixed plate, of the core pulling sliding seat is fixedly provided with a connecting block. A hydraulic cylinder is fixedlymounted on the mounting plate. The telescopic end of the hydraulic cylinder penetrates through the fixed plate to be fixedly connected with the connecting block. The other end of the core pulling sliding seat is fixedly connected with an electromagnet. The end, far away from the core pulling sliding seat, of the electromagnet is connected with a mounting template through a clamping block in a clamped mode. A molding core part is mounted on the mounting template. The plastic mold core pulling mechanism has the characteristics of being simple, practical and good in production quality.

Description

technical field [0001] The invention relates to the technical field of plastic molds, in particular to a plastic mold core-pulling mechanism. Background technique [0002] With the development of industrial technology, high-end industrial production has gradually entered people's lives. The production and design of various design products need to go through several steps such as drawing design, mold shaping and manufacturing. Injection molds are the most widely used in current industrial production. One of the most common molds is a processing method used in mass production of certain complex-shaped parts. [0003] At present, because the hydraulic device can provide a large core-pulling force, many plastic mold core-pulling mechanisms require a hydraulic device for core-pulling, but when the hydraulic device controls the core-pulling stroke, it is easy to produce errors and affect the mold forming; The core mechanism can only pull the core of a specific mold, and the scope...

[0003] At present, because the hydraulic device can provide a large core-pulling force, many plastic mold core-pulling mechanisms require a hydraulic device for core-pulling, but when the hydraulic device controls the core-pulling stroke, it is easy to produce errors and affect the mold forming; The core mechanism can only pull the core of a specific mold, and the scope of application is small. Different core pull mechanisms often require different core pull mechanisms for different molds.
