Abstract
The utility model provides a sprue structure of a thin-wall part, and the sprue structure is a hidden sprue. The sprue does not need to be manually removed so that the automatic separation of the sprue and a product is realized and the production efficiency is high. The sprue structure comprises an upper fixing plate, a sprue sleeve, a front die core and a rear die core; the upper end of the sprue sleeve is fastened on the upper fixing plate; and the lower end of the sprue sleeve is communicated with cavities which are formed by carrying out die assembly on the front die core and the back die core through a flow channel. The sprue structure is characterized in that the two cavities are formed by carrying out the die assembly on the front die core and the back die core; the back die core corresponding to the middle parts of the two cavities is a convex structure; one part of the convex structure, which corresponds to the front die core, is a concave structure; a material storage cavity is formed by matching the concave structure with the convex structure; the flow channel is communicated with the material storage cavity; and the two sides of the material storage cavity is communicated with the corresponding cavities through downward inclined closed thin holes.
Description
Technical field
The utility model relates to the injection structure technical field of injection mould mould, is specially a kind of pouring gate structure of thin-walled parts.
Background technology
For the production efficiency that improves mould and the stability of product quality.Usually our preferential submarine running gate system that adopts in mould structure design realizes automatically separating of cast gate and product when allowing product from mold ejection.But this submarine running gate system has certain requirement to the height dimension of the enterprising gate location of product, and the height that usually advances gate location is the following situation of 2mm, can't adopt common submarine structure.The pouring gate structure of existing thin-walled parts, it adopts the structure of side gate, and its cast gate needs the artificial removal, causes production efficiency low.
Summary of the invention
For the problems referred to above, the utility model provides a kind of pouring gate structure of thin-walled parts, and it is sub marine gate, need not artificial removal's cast gate, has realized automatically separating of cast gate and product, and production efficiency is high.
A kind of pouring gate structure of thin-walled parts, its technical scheme is such: it comprises upper mounted plate, sprue bush, front cavity, rear cavity, described sprue bush upper end is anchored on the fixed plate, described sprue bush lower end is communicated with described front cavity by runner, the cavity that forms behind the rear cavity matched moulds, it is characterized in that: form two described cavitys behind described rear cavity and the described front cavity matched moulds, described rear cavity corresponding to mid portion that is positioned at two described cavitys is convex configuration, described front cavity corresponding to described convex configuration partly is concave inward structure, described concave inward structure, form storage cavity between after convex configuration cooperates, described runner is communicated with described storage cavity, and described storage cavity is communicated with corresponding described cavity by the oblique lower closing in pore of both sides.
After adopting said structure of the present utility model, because runner flows into cavity by oblique lower closing in pore after flowing into storage cavity again, it is so that cast gate is sub marine gate, during the demoulding, need not artificial removal's cast gate, realized automatically separating of cast gate and product, production efficiency is high.
Description of drawings
Fig. 1 is front view structural representation of the present utility model;
Fig. 2 is the local structure for amplifying schematic diagram in the A place of Fig. 1.
The specific embodiment
See Fig. 1, Fig. 2, it comprises upper mounted plate 1, sprue bush 2, front cavity 3, rear cavity 4, sprue bush 2 upper ends are anchored on upper mounted plate 1, sprue bush 2 lower ends are communicated with front cavity 3 by runner 5, the cavity 6 that forms behind rear cavity 4 matched moulds, form two cavitys 6 behind rear cavity 4 and front cavity 3 matched moulds, rear cavity corresponding to mid portion that is positioned at two cavitys 6 is convex configuration 7, the part of the front cavity 3 of convex configuration 7 correspondences is concave inward structure 8, concave inward structure 8, form storage cavity 9 between after convex configuration 7 cooperates, runner 5 is communicated with storage cavity 9, and storage cavity 9 is communicated with corresponding cavity 6 by the oblique lower closing in pore 10 of both sides.
Claims (1)
