Abstract
The utility model discloses a wiredrawing -preventing sprue bush, including runner cover body and spacer, this runner cover body includes pulloverly and the loop bar, and this pullover middle part is equipped with the injecting glue runner, and the middle part of this loop bar is equipped with the gummosis passageway, and pullover injecting glue runner is put through with the gummosis passageway of loop bar mutually. Pullover upper portion is equipped with the injecting glue recess, and the bottom of injecting glue recess is equipped with the injecting glue mouth, and this injecting glue mouth is put through with pullover injecting glue runner mutually, has offered the spacer slot on the injecting glue recess, and the spacer inserts in this spacer slot. The end of the gummosis passageway of loop bar has the cooling notch, and should cool off notch along the end that radially runs through the loop bar. The inner of cooling notch is the arc. The utility model provides a pullover injecting glue mouth department is equipped with the spacer, can effectively prevent the wire drawing phenomenon so that the runner cooling puts in place. The end of the gummosis passageway of loop bar has the cooling notch, has accelerateed the injecting glue runner of whole runner cover and the cooling of the waste material in the gummosis passageway and has solidified, has guaranteed the drawing of patterns validity of runner waste material.
Description
Technical field
The utility model is related to injection molding technology field, particularly to a kind of anti-wire drawing sprue bush.
Background technology
In injection production process, sprue bush is used for allowing the plastic material of melting be injected into mould inside from the nozzle of injection machine
Runner.Sprue bush used in prior art is through-type, and in injection moulding process, the gate location cooling of product is slow, leads to
Cast gate, in the demoulding, produces a thread plastic cement when uncooled material pulls out from screw rod nozzle, causes wire drawing phenomenon.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of anti-wire drawing sprue bush, can prevent
During cast gate pull-out, wire drawing phenomenon occurs.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions：One
Plant anti-wire drawing sprue bush, including sprue bush body and partition, this sprue bush body includes pullover and is arranged on pullover bottom
Loop bar, the middle part of this pullover is provided with injecting glue runner, and the middle part of this loop bar is provided with gummosis passage, the injecting glue runner of pullover and loop bar
Gummosis passage is connected, and the top of pullover is provided with injecting glue groove, and the bottom of this injecting glue groove is provided with gum-injecting port, this gum-injecting port and set
The injecting glue runner of head is connected, and this injecting glue groove offers the partition slot through gum-injecting port, and partition is inserted into this partition and inserts
In groove, the end of the gummosis passage of described loop bar has cooling recess, and this cooling recess extends radially through the end of loop bar.
Further, described injecting glue groove is arc.
Further, the upper end of described partition is arc.
The beneficial effects of the utility model are：It is provided with partition, partition will be noted at the gum-injecting port of the pullover in the utility model
Glue runner is divided into two parts, so that cast gate cooling puts in place, effectively prevents wire drawing phenomenon.And, the gummosis of loop bar leads to
The end in road has cooling recess, thus coordinating with partition, accelerates in the injecting glue runner and gummosis passage of whole sprue bush
The cooled and solidified of waste material is it is ensured that the demoulding validity of cast gate waste material.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the structural representation of the partition in the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model
Define.
As shown in Figure 1 to Figure 3, a kind of anti-wire drawing sprue bush, including sprue bush body 1 and partition 2, this sprue bush body 1
Including pullover 11 and the loop bar 12 being arranged on pullover 11 bottom, the middle part of this pullover 11 is provided with injecting glue runner 111, this loop bar 12
Middle part be provided with gummosis passage 121, the injecting glue runner 111 of pullover 11 is connected with the gummosis passage 121 of loop bar 12.Pullover 11
Top is provided with injecting glue groove 112, and the bottom of this injecting glue groove 112 is provided with gum-injecting port 113, the note of this gum-injecting port 113 and pullover 11
Glue runner 111 is connected, and the cell wall of this injecting glue groove 112 offers the partition slot 114 through gum-injecting port 113, and partition 2 is inserted
Enter in this partition slot 114, and extend in the injecting glue runner 111 of pullover 11.The end of the gummosis passage 121 of described loop bar 12
End has cooling recess 122, and this cooling recess 122 extends radially through the end of loop bar.The inner of cooling recess 122 is arc
Shape.
Furtherly, described injecting glue groove 112 is arc.The upper end of described partition 2 is arc, thus the injecting glue with arc
Groove 112 coordinates.
During work, the melt plastic cement that the nozzle of injection machine sprays covers into injection mold via this cast gate.After injection mo(u)lding,
When taking out shaped article, the cast gate waste material in the sprue bush of cooled and solidified is taken out.The note of the pullover 11 in the utility model
It is provided with partition 2, injecting glue runner 111 is divided into two parts by partition 2, so that the cooling of cast gate waste material puts in place, effectively at glue mouth 113
Prevent wire drawing phenomenon.And, the end of the gummosis passage 121 of loop bar 12 has cooling recess 122, thus joining with partition 2
Close, accelerate the cooled and solidified of waste material in the injecting glue runner 111 and gummosis passage 121 of whole sprue bush it is ensured that cast gate gives up
The demoulding validity of material.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
The equivalent structure made using the utility model specification and accompanying drawing content or equivalent flow conversion, or be directly or indirectly used in
Other related technical fields, are all included in the same manner in scope of patent protection of the present utility model.
