Abstract
The invention discloses a novel pouring structure for a mould, comprising a main flow channel, branch flow channels, and pouring gate flow channels for connecting the branch flow channels with the main flow channel. The novel pouring structure is characterized in that the pouring gate flow channels are provided with irregular cavities, and recesses or bulges are arranged on the wall surfaces of the cavities. According to the invention, the instantaneous flow acceleration during glue inlet is slowed down, and the partial impact pressure on the pouring gate flow channels during the glue inlet is reduced by increasing the areas of the tube walls of the pouring gate flow channels, thus preventing the mould from deforming.
Description
Technical field
The invention belongs to the Mould Machining field, specifically is a kind of novel die casting structure.
Background technology
Cast gate is claimed charging aperture again, and it is the narrow and small port between runner and the die cavity on the mould, also is the shortest and the smallest part; Its effect is to make the material sizing material of fusion when advancing die cavity, produce acceleration, helps being full of rapidly die cavity, cast gate plastics elder generation condensation after the moulding; With near closed hollow ring, prevent that molten plastic from flowing backwards, it is too fast to avoid cavity pressure to descend; So that on goods, produce shrinkage cavity or depression, be convenient to make cast to coagulate material after the moulding and separate with goods.The ox horn type that rectangle, cylindrical or convergent are arranged of runner commonly used, runner be the cavity of rule variation basically.But the situation that cast gate is easy to deform is worked as under the situation that the sizing material temperature is higher, the sizing material acceleration is big in existing cast gate design.In the process of carrying out extra quality injection moulding, a kind of material in back when advancing glue, its instantaneous impulse force that sprays into die cavity sometimes also can to before the distortion that impacts of in type material, produce the situation of swoon line or depression.
Summary of the invention
Technical purpose of the present invention provides a kind of defective that overcomes prior art, provides a kind of and can slow down the into novel die cast structure of glue acceleration, reduction glue mouth pressurized.
Technical scheme of the present invention is:
A kind of novel die cast structure comprises sprue, branch's runner and the runner that is connected said branch runner and die cavity, it is characterized in that said runner has irregular cavity, and the wall of said cavity is provided with depression or protruding.
The middle part of said runner is provided with one section buffering adapter cavity, the interface that arbitrary cross section of said buffering adapter cavity is connected with the branch runner greater than runner at least.
The periphery of said runner is provided with cooling water channel.
Said depression and convexity are the curved surface shape or form with planar combination for domatic.
Behind the mould matched moulds, the beginning injection moulding, plastic cement gets into the product die cavity through runner; After colloid flows into runner, begin to quicken, irregular runner has increased the compression area of runner cavity, and its high spot can play the effect that stops colloid; Its recess or be called buffering area and can postpone colloid and go out the into flow and the speed of glue point; When extra quality injection moulding, reduced the instantaneous impulse force of laggard material to molded material, improve yield of products.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
In order to illustrate technical scheme of the present invention and technical purpose, the present invention is done further introduction below in conjunction with the accompanying drawing and the specific embodiment.
As shown in the figure; A kind of novel die cast structure; Comprise sprue, branch's runner and the runner that is connected said branch runner and die cavity 1; Said runner 1 has irregular cavity, and the wall of said cavity is provided with depression or protruding, and said depression and convexity are the curved surface shape or form with planar combination for domatic.
Of Fig. 1, the middle part of said runner 1 is provided with one section buffering adapter cavity, and said buffering adapter cavity is to being recessed on; After colloid gets into; Part colloid continues forward to flow, and another part then can be temporarily stored in the said buffering adapter cavity, reduces the impulse force of instantaneous plastic emitting.
Mould is provided with cooling water channel in the periphery of said runner 1, and the heat of mould is in time passed, prevent mould in continuous process because of the accumulation of heat distortion.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
