Injection molding device for plastic bend tube

Abstract

The invention relates to the technical field of injection molding, and discloses an injection molding device for a plastic bend tube. The injection molding device for the plastic bend tube comprises abase, a lower mold base, a lower mold, an upper mold, an upper mold cover, a first moving mechanism, a second moving mechanism, and a third moving mechanism; the lower mold base is arranged on the base; a first moving groove, a second moving groove, a third moving groove, and a mold groove are arranged on the lower mold base; the first moving groove is formed in the upper left part of the lower mold base; the second moving groove is formed in the right part of the lower mold base; the third moving groove is formed in the front part of the lower mold base; the mold groove is formed in the middle part of the lower mold base; the lower mold is arrangedin the mold groove, the first moving mechanism comprises a first component base, a first driving component, and a bend tube model bar; and thesecond moving mechanism comprises a second component base, a second driving component, and a bend tube model connecting rod; the third moving mechanism comprises a third driving component and a modelsliding block. The injection molding device for the plastic bend tube has the beneficial effects that the product can be artistic through the cold runner method, injection molding of the bend tube can be realized, the occurrence of the demolding track can be avoided, and product scrapping can be reduced.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a plastic elbow injection molding device. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding thermoplastics or thermosets into various shapes using plastic molding tools. Molds are often used in punching, forming stamping, die forging, cold heading, extrusion, powder metallurgy parts pressing, die casting, and in the forming process of compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific profile Or the shape of the inner cavity, the application of the contour shape with the cutting edge can make the blank separate according to the contour line shape, and the application of the inner cavity shape can make the blank obtain the corresponding three-dime...

AI Technical Summary

Problems solved by technology

However, in the prior art, the injection mold for producing tubular parts generally uses an upper mold and a lower mold to form the cavity of the product. When the mold is opened, it will inevitably leave mold opening marks on the parting surface of the product, and then will As a result, the appearance quality of the product does not meet the design requirements

The current core-pulling technology will often lead to core-pulling deviations, resulting in product scrapping caused by poor dimensions. There are many manufacturing defects in the current technology for curved products. At present, there is no good core-pulling device to solve the problem.
