Inclined-ejector demoulding mechanism

Abstract

The invention discloses an inclined-ejector demoulding mechanism, which comprises an ejector plate, an inclined-ejector base arranged on the ejector plate, a guide rod obliquely penetrating through the inclined-ejector base, an inclined-ejector rod with the lower end movably connected with the inclined-ejector base and an inclined-ejector block arranged at the upper end of the inclined-ejector rod; an included angle between the guide rod and the inclined-ejector rod is an acute angle; an inclined guide sliding groove is arranged on the inclined-ejector base, and the lower end of the inclined-ejector rod is connected with a sliding block matched with the inclined guide sliding groove; and the guide rod inclines towards the side where the inclined guide sliding groove is located. By using the inclined-ejector demolding mechanism, the situation that inclined-ejector self-locking occurs due to the fact that the inclined-ejector climbing or downhill angle is large can be avoided, the situation the inclined-ejector rod is bent and deformed during inclined-ejector ejecting out can be avoided, the structural stability of the inclined-ejector demolding mechanism is improved, the problem that an inverted buckle in a product inclines downwards or inclines upwards by an excessively large angle is solved, and the inclination angle of the inclined guide sliding groove can be designed to be smaller.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an inclined top demoulding mechanism. Background technique [0002] When there is an undercut structure inside the product, in order to ensure that the product can be demolded smoothly, it is usually necessary to design an inclined top demoulding mechanism on the mold. The demoulding of the general inclined top (slanted top demoulding mechanism) depends on the inclined top installed on the ejector plate. The top seat is realized, but the undercut of some products still has an upward or downward slope, or there are ribs or other structural interference in the direction of the undercut demoulding. At this time, the inclined top needs to do climbing or downhill movement to complete the undercut position Easy demoulding. In the prior art, for the large-angle inner undercut structure, the inclined roof design usually adopts the method of parallel inclined ejector rods and gui...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art above, the purpose of the present invention is to provide a slanted roof demoulding mechanism, which aims to solve the problems of the existing slanted roof demoulding mechanism due to the large climbing or descending angle of the sloping roof. As a result, the tilting mechanism is self-locking, and the tilting rod is easy to bend and deform.
