Abstract
The utility model relates to the technical field of pipe fitting manufacture, and aims to solve existing technical problems and provide a pipe fitting which can improve product performance, ensure product quality and prevent a sprue from perforation. The pipe fitting comprises a main pipe fitting body, wherein the sprue is formed in the main pipe fitting body, and a patch is arranged at the sprue and covers the sprue. According to the pipe fitting, the patch is arranged at the sprue and covers the whole sprue, and equivalently, the normal thickness of the pipe fitting is increased; gate layering in the trimming process of the sprue only happens to the patch, and the normal thickness of the pipe fitting is not affected, so that perforation cannot happen to the sprue in a drying oven, product performance can be improved, and product quality is ensured.
Description
Technical field
The utility model relates to tubing manufacturing technology field, more specifically, relates to a kind of pipe fitting that prevents cast gate perforation.
Background technique
In prior art, cast gate claims again material feeding mouth, is molten plastic enters die cavity last " door " together by pouring system, is the feeding-passage that connects runner and die cavity.Its effect is to make molten plastic in the time entering die cavity, produce acceleration, be conducive to be full of rapidly die cavity, the first condensation of cast gate plastics after moulding, with near closed hollow ring, prevent that molten plastic from flowing backwards, avoid cavity pressure to decline too fast, so that produce shrinkage cavity or depression on goods, after moulding, be convenient to make to pour into a mould solidifying material and separate with goods.
Pipe fitting, after molding and forming, all can have a cast gate on product surface, this cast gate need be pruned smooth, because adding oiling agent in its material prescription to reduce the friction between material, so mouth of a river layering in various degree all can appear in trimmed cast gate.In pipe fitting performance testing process, when baking oven, cast gate is easily bored a hole, and causes product performance not pass a test, and affects quality of product.
Model utility content
The utility model is intended to solve the problems of the technologies described above at least to a certain extent.
The purpose of this utility model is to provide one and can enhances product performance, and guarantees the pipe fitting that prevents cast gate perforation of quality of product.
The utility model solves the technological scheme that its technical problem adopts: a kind of pipe fitting that prevents cast gate perforation, comprise main pipe body, and described main pipe body has cast gate, and described cast gate place is provided with patch, and described patch covers described cast gate.
The utility model is provided with patch at cast gate place, and covers whole cast gate, and be equivalent to has increased a layer thickness in the normal thickness of pipe fitting.The mouth of a river layering occurring in cast gate dressing process also only appears at patch place, and on the normal thickness of pipe fitting, without impact, therefore can not bore a hole in cast gate place when baking oven, thereby can improve the performance of product, guarantees quality of product.
In one embodiment, the size of described patch and the size of cast gate match, thereby can not affect the overall appearance of product, save material simultaneously.
In one embodiment, the thickness of described patch is 10 ~ 30mm.Preferably, the thickness of described patch is 20mm, thus on the normal thickness of pipe fitting without impact, prevent cast gate place perforation, guarantee quality of product.
In a preferred implementation, described patch and main pipe body are integrated molding and forming, thereby produce by normal pipe fitting Shooting Technique while manufacture, and without changing technique and secondary operations, the method is simple to operate, easy for installation.
In one embodiment, described patch is triangle, does not affect the overall appearance of product.Certainly, in other embodiments, patch also can be other shapes, such as square, circle or other polygonals etc.
The beneficial effects of the utility model are: the utility model is provided with patch at cast gate place, and cover whole cast gate, and be equivalent to has increased a layer thickness in the normal thickness of pipe fitting.The mouth of a river layering occurring in cast gate dressing process also only appears at patch place, and on the normal thickness of pipe fitting, without impact, therefore can not bore a hole in cast gate place when baking oven, thereby can improve the performance of product, guarantees quality of product.While manufacture, produce by normal pipe fitting Shooting Technique, without changing technique and secondary operations, the method is simple to operate, easy for installation simultaneously.
Accompanying drawing explanation
Fig. 1 is an embodiment's of the utility model structural representation.
Fig. 2 is the enlarged view of A part in Fig. 1.
Accompanying drawing, only for exemplary illustration, can not be interpreted as restriction of the present utility model; For better explanation embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known features and explanation thereof may to omit be understandable.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1 and Figure 2, a kind of pipe fitting that prevents cast gate perforation of the present utility model, comprises main pipe body 1, and described main pipe body 1 has cast gate (not shown), and described cast gate place is provided with patch 2, and described patch 2 covers described cast gate.The size of wherein said patch 2 and the size of cast gate match, and are shaped as triangle step, and thickness is 10 ~ 30mm, are 20mm in the present embodiment, thus on the normal thickness of pipe fitting without impact, prevent cast gate place perforation, guarantee quality of product.
In the present embodiment, described patch 2 is integrated molding and forming with main pipe body 1, thereby produces by normal pipe fitting Shooting Technique while manufacture, and without changing technique and secondary operations, the method is simple to operate, easy for installation.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all mode of executions.All any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in the protection domain of the utility model claim.
