Abstract

The invention discloses a simple secondary ejecting mechanism. The simple secondary ejecting mechanism comprises a top plate, an upper template, a lower template, a cushion plate and a baseplate distributed from top to bottom; a gate is vertically formed in the middle position of the top plate and the upper template; a molding cavity insert and a molding core insert are mounted between the upper template and the lower template; a thimble baseplate, a thimble push plate and a thimble panel are mounted in the middle position of the upper part of the baseplate from bottom to top; a primary ejector rod ejected in the upper template is vertically mounted on the thimble baseplate; a secondary ejector rod, a pull rod and an inclined ejector rod ejected in the lower template are vertically mounted on the thimble panel; and the pull rod is mounted in the middle position between the secondary ejector rod and the inclined ejector rod. The simple secondary ejecting mechanism has the beneficial effects of: practicability, low production cost, simple structure, realization of secondary ejection of stripped molds, uniform stress of plastic products and improvement of the production efficiency and the quality of the plastic products.

Description

technical field [0001] The invention relates to an ejection mechanism in a mold, in particular to a simple secondary ejection mechanism. Background technique [0002] In the process of processing plastic products with molds, it is necessary to separate the metal molds from the plastic products. An ejector mechanism will be installed on the equipment to separate the mold from the plastic product. [0003] The existing ejection mechanism has a single structure and is basically one-time ejection. During the ejection process, the force is uneven, and the plastic product is easily damaged, which affects the quality of the plastic product. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a simple secondary ejection mechanism for the deficiencies of the prior art. [0005] In order to achieve the above object, the measures taken by the present invention: [0006] A simple secondary ejection mechanism, including a top ...
