Abstract
The utility model discloses a kind of molds that can effectively reduce burr generation, including cope, lower moulding box and type core, it is equipped at the top of the cope and pours mouth, type core is equipped in lower moulding box, is opened up in the die joint that the cope is contacted with lower moulding box around the circulation road of the die joint.The utility model is opened up in the die joint that cope is contacted with lower moulding box around the circulation road of the die joint, circulation road when molding inside can deposit certain air, it will receive the resistance of air compression during melt enters circulation road from the gap of die joint, it prevents melt from entering gap and generates burr, even if the gap that least a portion of melt enters die joint can also deposit in circulation road, since speed slows down, circulation channel temp is relatively low, melt is quickly cooled to the closure of annular here, and burr is avoided to continue to spread to the die joint at circulation road rear.
Description
Technical field
The utility model relates to technical field of mold, in particular to a kind of mold that can effectively reduce burr generation.
Background technique
Injection mold is generally made of cope, lower moulding box and mold core, and cope and lower moulding box have when molding
One die joint, though die joint is typically all to seal cooperation, since melt is excessive in the casting process of heavy parts,
Or it is close in order to pour, certain pressure can be applied, melt will be from parting under the action of self gravity and impressed pressure
It is spread in face, forms burr, the excessive processing cost for not only increasing the later period of burr, it is also possible to influence the quality of product.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of molds that can effectively reduce burr generation.
The technical solution of the utility model are as follows:
A kind of mold can effectively reduce burr generation, including cope, lower moulding box and type core, the cope top are set
Mouth is poured, type core is equipped in lower moulding box, is opened up in the die joint that the cope is contacted with lower moulding box around the die joint
Circulation road.
Further, the section in circulation road is round or rectangle.
Further, the section in circulation road is vertically disposed rectangle, and width is no more than 2mm.
Further, lower moulding box side is equipped with several auxiliary and pours mouth.
Further, several pile jackings is arranged in type in-core.
The utility model has the beneficial effect that
The utility model is opened up in the die joint that cope is contacted with lower moulding box around the circulation road of the die joint, ring
Runner 6 when molding inside can deposit certain air, when melt enters the process in circulation road from the gap of die joint
In will receive air compression resistance, prevent melt enter gap generate burr, even if least a portion of melt enters die joint
Gap can also deposit in circulation road, and since speed slows down, circulation channel temp is relatively low, and melt is quickly cooled to annular here
Closure, avoid burr continue to the die joint at circulation road rear spread.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is another cross section structure schematic diagram in the utility model circulation road.
In figure: 1- cope, moulding box under 2-, 3- type core, 4- pile jacking, 5- die joint, 6- circulation road, 7- pour mouth, and 8- is auxiliary
It helps and pours mouth.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
It is as shown in Figs. 1-2:
A kind of mold can effectively reduce burr generation, including cope 1, lower moulding box 2 and type core 3, the cope 1 push up
Portion, which is equipped with, pours mouth 7, and type core 3 is equipped in lower moulding box 2, opens up and surrounds in the die joint 5 that the cope 1 is contacted with lower moulding box 2
The circulation road 6 of the die joint 5.
Specifically, in order to facilitate processing, the section in circulation road 6 is round or rectangle.
Specifically, the section in circulation road 6 is vertically disposed rectangle, width is no more than 2mm, and narrow rectangle makes
It obtains melt cooling faster, so that melt reaches the gap that die joint 5 is closed in rear cooling rapidly in circulation road, burr is avoided to continue to expand
Exhibition.
Specifically, pouring for large-scale part, speed of perfusion can be accelerated by pouring mouth using auxiliary, and melt is avoided to pour
Overlong time so as to cause each position the too big influence pouring quality of the melt temperature difference, therefore 2 side of lower moulding box be equipped with it is several auxiliary
It helps and pours mouth 8.
Specifically, take out product for convenience, several pile jacking 4 of setting in type core 3, pile jacking 4 take hydraulic-driven or
Motor driven all may be used.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
