Abstract

The invention provides a gripping device for clamping and taking out multicavity injected shaped parts. The shaped part comprises a material rod and a connecting rod formed by extended ends of a plurality of material rods. The gripping device comprises a fixed framework, a plurality of gripping jaws, a sleeve and a linear drive unit. Each gripping jaw comprises a gripping jaw body and an elastic element which fixes the gripping jaw body on the fixed framework. The plurality of gripping jaw bodies are distributed in a bunchy shape. A gap for accommodating a corresponding connecting rod is located between every two adjacent gripping jaw bodies. The sleeve is sleeved around the gripping jaw bodies from the end where a plurality of elastic elements are located, and constrains the gripping jaw bodies. The linear drive unit is fixed on the fixed framework for driving the sleeve to move towards a direction far from the elastic elements and to reset. The gripping device provided in the invention clamps and takes out shaped parts through a plurality of connecting rods so as to realize demoulding, which enables deformation or fracture of the connecting rods to be avoided and quality of demoulding to be improved.

Description

technical field

[0001] The invention relates to a clamping device, in particular to a clamping device for clamping multi-cavity injection molded parts. Background technique

[0002] At present, multi-cavity injection molded parts can be clamped and demolded by clamping devices. The existing gripping device is generally a two-jaw type gripping device, which can only grip rod-shaped objects. Therefore, currently, the material rod (formed in the sprue of the mold) of the molded part is usually clamped by a two-jaw type clamping device to demould the molded part. However, if the adhesive force between the molded part and the mold is large, the stripping of the material rod clamping the molded part may cause the deformation or breakage of the connecting rod (formed in the runner (runner) of the mold) of the molded part, making the entire molding Parts are deformed or the molded parts cannot be completely demoulded, and the demoulding quality is low.
