Abstract
The invention discloses a sprue used for an exterior face of an automobile emergency key bit. The sprue comprises a sprue fracture area and a sprue bottom, the sprue fracture area is a straight extension face, and the upper portion of the sprue fracture area is connected with a main runner; the sprue bottom is connected with the exterior face of the automobile emergency key bit, and the cross section of the sprue bottom is in a trapezoidal shape; the sprue fracture area and the sprue bottom are integrally formed. According to the sprue, due to the fact that the straight extension face serving as the sprue fracture area is added to the sprue area, the sprue fracture position is relatively fixed, furthermore, it is guaranteed that the dimension remaining after the fracture is relatively stabilized, meanwhile, band elimination of product plastic bits is avoided, thereby subsequent polishing cost can be controlled, and meanwhile the stable qualified rate of qualified products of the sprue-removal link is guaranteed.
Description
Technical field
The present invention relates to cast gate, be specifically related to a kind of cast gate of the appearance for automobile emergency key bit.
Background technology
Zinc alloy product is after the production of die casting first link terminates, and must need to carry out expecting handle for product, when conventional cast gate is removed, the position that material handle ruptures is uncertain, little time large when easily causing residual, is sometimes affixed on product face but can be with except product feature.For the part that appearance requirement is high, according to the gate design of routine, residual conference causes follow-up polishing time to lengthen, and the cost of part increases, and band then directly causes bad except product feature, causes the increase of the direct cost developed.
The die casting of kirsite, conventional removal expects that handle (i.e. gate portions) wishes that fracture position fits in product face, does not produce unnecessary defective material and exceeds product face, interfere to ensure that product does not produce to relevant Assembly part.But for the automobile emergency key bit 5 of special appearance parts such as shown in Fig. 4, its architectural feature causes can only selecting in appearance 4 into cast gate, when now just must consider to remove material handle, fracture position can not fit in product, otherwise when easily causing material handle, band removes product glue position.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of cast gate of the appearance for automobile emergency key bit.
To achieve these goals, the present invention is by the following technical solutions:
For a cast gate for the appearance of automobile emergency key bit, described cast gate comprises bottom the cast gate region of fracture and cast gate, and the described cast gate region of fracture is face, Shen always, and the top of the described cast gate region of fracture is connected with sprue;
Be connected with the appearance of described automobile emergency key bit bottom described cast gate, and the cross section bottom described cast gate is trapezoidal;
One-body molded bottom the described cast gate region of fracture and described cast gate.
Further, the thickness of the described cast gate region of fracture is 0.3mm ~ 0.5mm.
Further, the thickness of the described cast gate region of fracture is 0.4mm.
Further, the width entering cast gate of the described cast gate region of fracture is 0.3mm ~ 0.5mm.
Further, the width entering cast gate of the described cast gate region of fracture is 0.4mm.
Further, the angle of the two side bottom described trapezoidal cast gate is 20 ° ~ 40 °.
Further, the angle of the two side bottom described trapezoidal cast gate is 26 °.
Further, the angle of sprue oral area is 45 ° ~ 60 °.
Further, the angle of sprue oral area is 60 °.
Compared with prior art, the Advantageous Effects of the cast gate of the appearance for automobile emergency key bit of the present invention is: owing to being provided with face, straight Shen at gate area place as the cast gate region of fracture, the position that cast gate is ruptured is in specific regional extent, namely cast gate ruptures in specific region, its position is relatively fixing, and then ensure that post-rift remaining is a metastable size, avoid the glue position of band except product simultaneously, thus reach the follow-up polishing cost of control, also ensure the stable qualification rate of removing the qualified products of cast gate link simultaneously.

Bottom the 1 cast gate region of fracture, 2 cast gates, the appearance of 3 sprues, 4 automobile emergency key bits, 5 automobile emergency key bits, 6 enter cast gate, 7 sprue oral areas, the angle of B cast gate two bottom sides wall, the angle of C sprue oral area, the thickness of the T cast gate region of fracture, W enter cast gate width.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As Figure 1-3, the cast gate of the appearance for automobile emergency key bit of the present invention to comprise bottom the cast gate region of fracture 1 and cast gate 2, the cast gate region of fracture 1 is face, Shen always, namely, the two side of the cast gate region of fracture 1 be arranged in parallel, the angle of two side is 0 degree in other words, and the top of the described cast gate region of fracture 1 is connected with sprue 3; Bottom cast gate, 2 are connected with the appearance 4 of automobile emergency key bit 5, and bottom cast gate, the cross section of 2 is trapezoidal; Bottom the cast gate region of fracture 1 and cast gate, 2 is one-body molded.
In a preferred embodiment, the thickness T of the cast gate region of fracture 1 is 0.3mm ~ 0.5mm.In a preferred embodiment, the thickness T of the cast gate region of fracture 1 is 0.4mm.The thickness of the cast gate region of fracture 1 should ensure the quality of filling, and also will guarantee to carry out cast gate with less power.
In a preferred embodiment, the width W entering cast gate 6 of the cast gate region of fracture 1 is 0.3mm ~ 0.5mm.In a preferred embodiment, the width W entering cast gate 6 of the cast gate region of fracture 1 is 0.4mm.
In a preferred embodiment, bottom cast gate, the included angle B of two side of 2 is 20 ° ~ 40 °.In a preferred embodiment, bottom cast gate, the included angle B of two side of 2 is 26 °.
In a preferred embodiment, the angle C of sprue oral area 7 is 45 ° ~ 60 °.In a preferred embodiment, the angle C of sprue oral area 7 is 60 °.
Owing to being provided with face, straight Shen at gate area place as the cast gate region of fracture 1, the position that cast gate is ruptured is in specific regional extent, namely cast gate ruptures in specific region, its position is relatively fixing, and then ensure that post-rift remaining is a metastable size, avoid the glue position of band except product simultaneously, thus reach the follow-up polishing cost of control, also ensure the stable qualification rate of removing the qualified products of cast gate link simultaneously.
