Multi-angle core pulling mechanism of injection mold

Abstract

The invention relates to a multi-angle core pulling mechanism of an injection mold. The multi-angle core pulling mechanism comprises a lower oil cylinder, a transmission sliding block and two lower core pulling sliding blocks. The transmission sliding block is driven by the lower oil cylinder to slide in a moving die. The end face, away from the lower oil cylinder, of the transmission sliding block is made into an inverted V shape. Guide sliding blocks are fixedly mounted on two inclined faces of the end face of the inverted V shape of the transmission sliding block. A guide sliding groove isformed in the end face, close to the transmission sliding block, of each lower core pulling sliding block. Guide sliding plates cooperating with the guide sliding grooves are arranged on the guide sliding blocks. The tops of the two groove walls of each guide sliding groove are bent inwards to hook the corresponding guide sliding plate. The lower oil cylinder is also mounted on the moving die. Bymeans of the core pulling mechanism, core pulling of different angles can be achieved, and the multi-angle core pulling requirement under the condition that multiple core pulling mechanisms cannot bearranged due to space limiting can be met.

Description

[0001] This invention is a divisional application of the invention patent application with the application number 2017113851335, the application date is December 20, 2017, and the invention name is "Injection Mold Multi-angle Laminated Core Pulling Mechanism". technical field [0002] The invention relates to the technical field of injection molds, in particular to a multi-angle core-pulling mechanism for injection molds. Background technique [0003] The core-pulling mechanism is one of the most common mechanisms in injection molds, and is generally designed at the undercut position of the product. At present, the commonly used core-pulling mechanism is that the inclined guide column drives the core-pulling slider to perform core-pulling, that is, when the movable and fixed mold is opened, the inclined guide column drives the core-pulling slider to move, so that the core is separated from the product to facilitate product demoulding. However, the conventional inclined guide...

Problems solved by technology

However, the conventional slanted guide column drives the core-pulling slider to move in only one direction. When there are longitudinal and multiple directions of core-pulling in a small space, the conventional core-pulling scheme will no longer be applicable.
