Abstract
The utility model relates to the technical field of power communication pipe parts and particularly relates to a structure for preventing an inner angle of a PVC (Poly Vinyl Chloride) wire slot from glue injection and deformation. The structure for preventing the inner angle of the PVC wire slot from glue injection and deformation comprises a main runner and a pouring gate connected with the main runner, wherein the section of the pouring gate is trapezoidal. The structure provided by the utility model is simple and novel and short in injection molding route, the quality of products is ensured, the products are easy to trim, and the comprehensive cost of the products is low.
Description
Technical field
The utility model relates to the technical field of power communication pipe fitting, more specifically, relates to the structure that a kind of PVC of preventing wire slot integral angle enters glue distortion.
Background technology
The wiring duct of existing application enters plastic structure with PVC groove interior angle, and its structure as Figure 1-3.Its flow passage system is comprised of sprue 1, runner 2 and cast gate 3.Because runner 2 and cast gate 3 are respectively 2, and the mode that connects cast gate with single runner is respectively distributed in the left and right sidewall of groove interior angle product 4 package size ends suitable for reading.Because product is cooling after production, solidify, the cooling contraction of flow passage system, causes the internal contraction distortion toward groove interior angle by the sidewall suitable for reading of product of left and right runner 2 and cast gate 3.As Figure 4-Figure 6, its package size a suitable for reading is due to the inside contraction distortion of groove interior angle product 4 for product structure after production, and package size a suitable for reading is less than end opening package size b, and in figure, c represents the direction of groove interior angle product 4 inside contraction distortions.So existing, enter gluing method and cause the package size a suitable for reading of groove interior angle product 4 to dwindle because of distortion, b differs larger with end opening package size.When supporting with wire casing, end opening end is supporting qualified, but end suitable for reading can be supporting tight, is even difficult to supporting.Therefore existing to enter plastic structure defect larger, and applicability is very low, is badly in need of improving.
Summary of the invention
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 the structure that a kind of PVC of preventing wire slot integral angle enters glue distortion, and simple in structure, novel, injection moulding stroke is short, product quality is guaranteed, and product is pruned easily, and the product integrated cost of production is low.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of PVC of preventing wire slot integral angle enters the structure of glue distortion, wherein, comprises sprue, the cast gate being connected with sprue, and the cross section of described cast gate is trapezoidal.Described cast gate is vertical with sprue to be arranged.Described cast gate quantity is one.
The structure of entering glue distortion be by sprue from the vertical button bit of groove interior angle product die sinking direction directly single cast gate enter glue and complete.Between sprue and cast gate, being that side joint is vertical is connected.The cast gate of the method is except die joint, and its excess-three face is all provided with the trapezoid cross section cast gate of gradient, and injection area is large, the pressure loss of injection moulding is low etc.Product upper and lower opening package size after production is consistent, and product quality is high.
Compared with prior art, beneficial effect is: of the present utility model simple in structure, novel, injection moulding stroke is short, product quality is guaranteed, and product is pruned easily, and the product integrated cost of production is low.

The specific embodiment
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; For better explanation the present 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.In accompanying drawing, describe position relationship only for exemplary illustration, can not be interpreted as the restriction to this patent.
As Figure 7-9, a kind of PVC of preventing wire slot integral angle enters the structure of glue distortion, wherein, comprises sprue 10, the cast gate 20 being connected with sprue 10, and the cross section of cast gate 20 is trapezoidal.Cast gate 20 setting vertical with sprue 10.Cast gate 20 quantity are one.
The structure of entering glue distortion be by sprue 10 from the vertical button bit of groove interior angle product 50 die sinking directions directly single cast gate 20 enter glue and complete.To be that side joint is vertical with 20, cast gate be connected sprue 10.The cast gate of the method is except die joint 30, and its excess-three face is all provided with the trapezoid cross section cast gate of gradient, and injection area is large, the pressure loss of injection moulding is low etc.Product upper and lower opening package size after production is consistent, and product quality is high.In figure, 50 represent groove interior angle product, use the groove interior angle product 50 after the structure of originally entering glue distortion, and its package size a suitable for reading and end opening package size b are consistent, and product quality is high.
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 embodiment 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 exhaustive without also giving all embodiments.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.
