Abstract
The invention discloses a sprue bush, which relates to the field of injection molding machines. The sprue bush comprises a bush head and a body, wherein the bush head is cylindrical; a through fluid channel is arranged between the bush head and the body; a groove is formed in the upper part of the bush head and is communicated with the fluid channel; a slot is formed in the bush head and penetrates through the circle center of the upper surface of the bush head; a shunt spacer is arranged in the slot and extends into the fluid channel at preset length to divide the fluid channel into two parts. Because of the shunt spacer, the sprue bush has a good wiredrawing prevention effect. The sprue bush is simple in structure and convenient to use.
Description
Technical field
The present invention relates to the injection machine field, particularly a kind of sprue bush.
Background technology
Sprue bush is that a kind of device for plastic cement injection moulding field also is sprue bushing, Guan Zui, its role is to connect injection machine and mould is finished filling process.Conventional apparatus is taken out the back in formed product, and it terminally can produce wire drawing phenomenon, also has the appearance of defective material simultaneously in runner, and next this can influence undoubtedly that the quality of product has also increased production cost simultaneously.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is, a kind of sprue bush of anti-wire drawing is provided, and has anti-wire drawing effect preferably.
(2) technical scheme
In order to address the above problem, the invention provides a kind of sprue bush, described sprue bush comprises: pullover and body, described pullover be cylindrical, described pullover and body is provided with the fluid passage of perforation, described pullover top is provided with groove, described groove is communicated with described fluid passage, the described pullover draw-in groove that is provided with, described draw-in groove is by the center of circle of described pullover upper surface, described draw-in groove is provided with the shunting partition, and described shunting partition becomes preset length to extend to inside, described fluid passage, and described fluid passage is divided into two parts.
Wherein, described shunting partition is located at the center that part in the described fluid passage is positioned at described fluid passage.
Wherein, the groove on described pullover top is bowl-shape.
(3) beneficial effect
The present invention is because the setting of shunting partition has anti-wire drawing effect preferably, and it is simple in structure, and is easy to use.
Description of drawings
Fig. 1 is the cutaway view of sprue bush of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
With reference to shown in Figure 1, described sprue bush comprises: pullover 5 and body 6, described pullover 5 is cylindrical, described pullover 5 and body 6 be provided with the fluid passage 1 of perforation, described pullover 5 tops are provided with groove 3, described groove 3 is communicated with described fluid passage 1, described pullover 5 are provided with draw-in groove, and described draw-in groove is by the center of circle of described pullover upper surface, and described draw-in groove is provided with shunting partition 2,2 one-tenth preset length of described shunting partition extend to 1 inside, described fluid passage, and described fluid passage 1 is divided into two parts.
Preferably, described shunting partition 2 is located at the center that part in the described fluid passage 1 is positioned at described fluid passage 1.
Preferably, the groove 3 on described pullover 5 tops is bowl-shape, is convenient to charging.
The raw material of product end is usually because area of dissipation is little when product takes out, and self thicker reason causes cooling off not in place and produces wire drawing.The effect of shunting partition just has been to increase the area of dissipation of raw material herein, has accelerated the cooled and solidified of molten plastic, thereby has reached the effect that prevents wire drawing.
Above embodiment only is used for explanation the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
Claims (3)
1. sprue bush, it is characterized in that described sprue bush comprises: pullover and body, described pullover be cylindrical, described pullover and body is provided with the fluid passage of perforation, described pullover top is provided with groove, and described groove is communicated with described fluid passage, the described pullover draw-in groove that is provided with, described draw-in groove is by the center of circle of described pullover upper surface, described draw-in groove is provided with the shunting partition, and described shunting partition becomes preset length to extend to inside, described fluid passage, and described fluid passage is divided into two parts.
2. sprue bush as claimed in claim 1 is characterized in that, described shunting partition is located at the center that part in the described fluid passage is positioned at described fluid passage.
