Abstract
The utility model discloses a gate scour-flanging preventing structure of a secondary injection mold for double blanking elements, which comprises an injection mold, the injection mold is composed of a mold core and a mold cavity, and a gate is arranged between the mold core and the mold cavity; the structure is characterized in that the mold cavity is provided with a downwards-raised step surface at the gate, the downwards-raised step surface is in a downwards-raised shape relative to a parting surface, and the vertical distance difference between the downwards-raised step surface and the parting surface is 0.2-0.3 mm. The structure disclosed by the utility model has the beneficial effects that the downwards-raised step surface is lower than the parting surface, so that a situation that the edges of parts are subjected to scour flanging can be effectively prevented in the process of secondary injection molding, thereby improving the qualified rate of secondary injection molding products.
Description
Technical field
The utility model relates to the quadric injection mould mould applications, particularly a kind of extra quality blocking piece quadric injection mould mould gate erosion control turnup structure.
Background technology
Referring to illustrated in figures 1 and 2, the cast gate of existing quadric injection mould mould 1 and die joint 2 at grade, the part edge that embeds mould during quadric injection mould is easily rushed flange and is scrapped, and affect operating efficiency, the increase production cost.
In sum, for shortcomings and deficiencies of the prior art, need especially a kind ofly can prevent effectively that part edge from being rushed the extra quality blocking piece quadric injection mould mould gate erosion control turnup structure of flange, to address the above problem.
The utility model content
The purpose of this utility model is to provide a kind of extra quality blocking piece quadric injection mould mould gate erosion control turnup structure.
The technical problem that the utility model solves can realize by the following technical solutions:
Extra quality blocking piece quadric injection mould mould gate erosion control turnup structure, comprise the injection mold that is formed by core and die cavity, be provided with cast gate between described core and die cavity, it is characterized in that, described die cavity is provided with one and is the lower convex platform terrace of lower convex with respect to die joint at the cast gate place.
In a kind of preferred embodiment of the present utility model, the vertical range between described lower convex platform terrace and described die joint is poor is 0.2mm～0.3mm.
Owing to having adopted technical scheme as above, the beneficial effects of the utility model are: the lower convex platform terrace can effectively prevent that lower than die joint part edge from being rushed flange when quadric injection mould, improves the quadric injection mould product percent of pass.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the quadric injection mould mould of prior art.
Fig. 2 is the structural representation at the quadric injection mould mould gate place of prior art.
Fig. 3 is the structural representation of the extra quality blocking piece quadric injection mould of the utility model mould gate erosion control turnup structure.
Fig. 4 is the structural representation at the extra quality blocking piece quadric injection mould of the utility model mould gate erosion control turnup structure cast gate place.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 3 and shown in Figure 4, extra quality blocking piece quadric injection mould mould gate erosion control turnup structure comprises the injection mold that is comprised of core 200 and die cavity 100, part 300 is embedded between core 200 and die cavity 100, be provided with cast gate 600 between core 200 and die cavity 100, die cavity 100 is provided with one and is the lower convex platform terrace 500 of lower convex with respect to die joint 400 at cast gate 600 places, the vertical range between lower convex platform terrace 500 and die joint 400 is poor is 0.2mm～0.3mm.
When quadric injection mould, watered PUR 700 in cast gate 600, the vertical drop between lower convex platform terrace 500 and die joint 400 can prevent effectively that part 300 edges from being rushed flange, improves the quadric injection mould product percent of pass.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. extra quality blocking piece quadric injection mould mould gate erosion control turnup structure, comprise the injection mold that is formed by core and die cavity, be provided with cast gate between described core and die cavity, it is characterized in that, described die cavity is provided with one and is the lower convex platform terrace of lower convex with respect to die joint at the cast gate place.
2. extra quality blocking piece quadric injection mould mould gate erosion control turnup structure as claimed in claim 1, is characterized in that, the vertical range between described lower convex platform terrace and described die joint is poor is 0.2mm～0.3mm.
