Problems solved by technology

However, due to the complex structure of some products and strong adhesion between the molded cavity and the cavity after molding, it is necessary to use a large driving force to push out. The above situation will be affected by great resistance when the mold is opened. When the product is ejected by a single push plate or a push rod push mechanism, it will cause damage to the product, resulting in a decrease in the yield of the product

Embodiment Construction

[0013] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0014] Such as figure 1 As shown, the composite push-out mechanism is used to release the product 6 from the mold. The mold includes a fixed template 2 and a movable template 1. The fixed template 2 is set opposite to the movable template 1. The composite push-out mechanism includes a pusher plate 3, at least one Main push rod 4 and at least one auxiliary push rod 5, attached figure 1 Only a main push rod 4 and an auxiliary push rod 5 are schematically drawn in the drawing. The pusher plate 3 is arranged between the fixed template 2 and the movable template 1, the pusher plate 3 is provided with a through hole 3a, the fixed template 2 has a convex mold part 2a for forming the product 6, and the movable template 1 has a co...

Abstract

The invention provides a compound push-out mechanism, which belongs to the technical field of machinery. It solves the problem that demoulding easily leads to product damage in the prior art. The composite push-out mechanism includes a pusher plate, at least one main push rod and at least one auxiliary push rod. The pusher plate is arranged between the fixed template and the movable template. The punch part of the product forming, the movable plate has a groove corresponding to the punch part, the notch of the groove is larger than the through hole, and the orthographic projection of the notch can completely cover the orthographic projection of the through hole, and the punch part passes through the through hole Entering into the groove of the movable template and cooperating with the groove to form a mold cavity, the main push rod is pierced on the fixed template and can reach the cavity, and the auxiliary push rod is pierced on the fixed template and can abut against the push piece plate. The composite push-out mechanism has simple structure, convenient demoulding, and can effectively prevent products from being damaged due to demoulding.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a push-out mechanism, in particular to a composite push-out mechanism. Background technique [0002] Generally, when you want to take the formed product out of the mold, you use the ejector mechanism. The ejector mechanism uses the method of applying thrust to the fixed plate to drive multiple thimbles against the product through the fixed plate, so that the thimble will push the formed product. Lift off from the mold. However, due to the complex structure of some products and strong adhesion between the molded cavity and the cavity after molding, it is necessary to use a large driving force to push out. The above situation will be affected by great resistance when the mold is opened. When a product is ejected by a single push plate or a push rod pushing mechanism, it will cause damage to the product, resulting in a decrease in the yield of the product. Contents of the inventi...
