Description
Technical field
The utility model relates to mould applications, particularly relates to a kind of mold insert structure that prevents product filling defect.
Background technology
In the production field of some telecommunication parts, especially this series products of astigmatism backing, all there is muscle, blade and single chamber in each portion of these products, in process of production, it fills the phenomenon that end tends to produce exhaust problem, and after dissecing, can find has pore in wall thickness position, and also there are the forming defects such as lack of fill, cold shut on apparent thick muscle top simultaneously, these all defects have directly caused the qualification rate of product to decline, and have affected production.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of mold insert structure that prevents product filling defect, simple in structure, on core rod, arrange some air gaps, and all arrange circular hole at the two ends of air gap, make product exhaust up and down in process of production, thereby reduce the appearance of pore, improve the qualification rate of product.
The utility model solves the technical scheme that its technical problem adopts: a kind of mold insert structure that prevents product filling defect is provided, comprise solid plate, moving platen and runner, described solid plate and moving platen are up and down to be arranged, in the middle part of between, corresponding position is furnished with respectively cover half core and moving-mould-core, described cover half core and moving-mould-core are in contact with one another and form die cavity, described runner is arranged in template and is connected with core rod, described runner is by the sprue gate of its front end and be connected with the circuit insert plate being arranged on core rod, described circuit insert plate outside, parallel with the long limit of core rod and be equidistantly furnished with some forming tank, described forming tank bottom, be furnished with along its length the air gap corresponding with defective locations on product muscle, and the two ends of every air gap are all furnished with circular hole.
As a kind of of mold insert structure described in the utility model, supplement, the bottom of described forming tank is furnished with some flat push rods, and product is played to the effect of ejecting.
Another kind as mold insert structure described in the utility model supplements, and the width of described air gap is 0.2mm, and the diameter of described circular hole is 0.5mm.
As a kind of optimal way of mold insert structure described in the utility model, described air gap and circular hole all communicate with core rod bottom, make product exhaust up and down in process of production.
As also having of mold insert structure described in the utility model is a kind of, supplement, described core rod is cover half core or moving-mould-core.
beneficial effect
The utility model relates to a kind of mold insert structure that prevents product filling defect, simple in structure, arranges some air gaps on core rod, and all arrange circular hole at the two ends of air gap, make product exhaust up and down in process of production, thereby reduce the appearance of pore, improve the qualification rate of product.
