Embodiment Construction

[0008] See figure 1 , which includes a front mold 1, a rear mold 2, and an insert. A cavity 3 is formed between the front mold 1, the rear mold 2, and the insert. The insert includes an outer insert 4 and an inner insert 5. The outer insert 4 is specifically Two pieces, two outer inserts 4 are combined to form a circular structure, the outer side of the outer insert 4 is clamped in the oblique T-shaped guide rail 10, the T-shaped guide rail 5 is arranged obliquely upward, and the lower part of the outer insert 4 is provided with The insert thimble 6, the bottom of the insert thimble 6 is fastened to the installation cavity between the needle plate 7 and the backing plate 8, the upper end surface of the top seat 9 is mounted on the lower end surface of the front mold 1, and the circumference of the top seat 1 is tight. Inherent inner insert 5, the upper side end surface of the inner insert 5 is close to the lower end surface of the cavity 3, the bottom of the top seat 9 is fast...

Abstract

The invention provides a two-stage ejection mechanism of a mold. The two-stage ejection mechanism can realize one-step molding of a product of which the side is provided with a transverse bulge, and has high production efficiency. The two-stage ejection mechanism comprises a front mold, a rear mold and inserts. A cavity is formed among the front mold, the rear mold and the inserts. The two-stage ejection mechanism is characterized in that the inserts comprise two outer inserts and inner inserts; the two outer inserts form a circumferential structure; outer sides of the outer inserts are blocked in inclined T-shaped guide rails; the T-shaped guide rails incline upward; insert ejector pins are arranged above the outer inserts; bottoms of the insert ejector pins are fastened to an installation chamber between an ejector retainer plate and a base plate; an upper end surface of a footstock presses against a lower end surface of the front mold; the inner inserts are fastened to the periphery of the footstock; and upper side surfaces of the inner inserts tightly press against a lower end surface of the cavity.

Description

technical field [0001] The invention relates to the structural technical field of product molds, in particular to a secondary ejection mechanism of a mold. Background technique [0002] Existing products with laterally protruding side parts cannot be molded at one time with existing molds. After the overall manufacturing is completed, follow-up processing is required to complete the production of the entire product, and its production efficiency is low. Contents of the invention [0003] The invention provides a secondary ejection mechanism of a mold, which can form a product with a lateral protrusion at one time, so that the production efficiency is high. [0004] A secondary ejection mechanism for a mould, the technical solution of which is as follows: it includes a front mold, a back mold, and an insert, and a mold cavity is formed between the front mold, the back mold, and the insert, and it is characterized in t...
