Abstract
The utility model discloses one kind preventing injection molding flash mechanism, it is characterized in that, it includes workpiece and unit of plastic, outer workpiece is provided with matched upper mold component and lower die assembly, upper mold component and the contact site of lower die assembly and workpiece are respectively arranged with compression soft rubber, respectively upper rubber and lower rubber, unit of plastic is arranged in the end of workpiece, it further includes movable limit assembly, movable limit assembly setting is made of in lower mold component internal, movable limit assembly limited block, movable bullet block and spring part.The utility model is provided with compressible workpiece activity limit assembly by unit of plastic, since component is made of movable bullet block, spring and limit block part, the setting of limited block makes movable bullet block workpiece will not be caused to rupture because strength is excessive, and plastic flash is in the presence of because glass size is less than mould standard when the setting of movable bullet block can block injection molding.
Description
Technical field
The utility model is related to plastic mould production field, more particularly to one kind preventing injection molding flash mechanism.
Background technology
The common technology that plastic edge is plastic processing industry is added on glass, is usually applied to the rings such as the interlayer board of refrigerator
Border can not damage glass by pressure in mold clamping, otherwise crush glass to be molded in glass outer.Through statistics, practical glass
Glass compartment thickness is between 3.82 ~ 4.1, and about 70% between 3.82 ~ 4.0, therefore mold sealing face design gaps press 4.5+-0.03；
It is calculated by tolerance, between sealing face gap about 0.0.25 ~ 0.1 of most of glass and mold, and the injection molding of plastic material PP is permitted
Perhaps gap be 0.03, more than then be injection moulded after there is overlap.Previous way is that occur overlap after depanning directly to repair by hand
It manages, is easy to damage frosting under which, leads to high rejection rate.
Utility model content
The technical problems to be solved in the utility model is：In view of the above shortcomings of the prior art, providing one kind prevents from being molded
Flash mechanism.
The solution that the utility model solves its technical problem is：
One kind preventing injection molding flash mechanism, which is characterized in that it includes workpiece and unit of plastic, outer workpiece setting
There is the contact site of matched upper mold component and lower die assembly, the upper mold component and lower die assembly and workpiece
It is respectively arranged with compression soft rubber, respectively upper rubber and lower rubber, the unit of plastic are arranged in the end of workpiece, it is also wrapped
Movable limit assembly is included, the movable limit assembly is arranged in lower mold component internal, and the movable limit assembly is by limiting
Position block, movable bullet block and spring part composition.
As one of preferred technical solution, which is characterized in that the workpiece is glass pieces.
As one of preferred technical solution, which is characterized in that the limited block and movable bullet block are arranged in lower mold
The top of component simultaneously contacts the workpiece.
The utility model has the beneficial effects that：The utility model is provided with compressible workpiece activity limit group by unit of plastic
Part, since component is made of movable bullet block, spring and limit block part, the setting of limited block so that movable bullet block will not be because of strength
It is excessive and workpiece is caused to rupture, and when setting of movable bullet block can block injection molding, moulds because glass size is less than mould standard
Expect the situation of flash.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete
Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings it
His design scheme and attached drawing.
Fig. 1 is the schematic cross-sectional view of the utility model.
Specific implementation mode
The technique effect of the design of the utility model, concrete structure and generation is carried out below with reference to embodiment and attached drawing
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
The other embodiment that art personnel are obtained without creative efforts belongs to the model of the utility model protection
It encloses.In addition, all connection/connection relations being previously mentioned in text, not singly refer to component and directly connect, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more preferably coupling structure.Each technology in the utility model creation
Feature, can be with combination of interactions under the premise of not conflicting conflict.
As shown in Figure 1, one kind preventing injection molding flash mechanism, which is characterized in that it includes workpiece 1 and unit of plastic 3, workpiece 1
Outside is provided with matched upper mold component 21 and lower die assembly 22, upper mold component 21 and lower die assembly 22 and work
The contact site of part 1 is respectively arranged with compression soft rubber, and respectively upper rubber 31 and lower rubber 32, unit of plastic 3 are arranged in workpiece 1
End, it further includes movable limit assembly, and movable limit assembly is arranged inside lower die assembly 22, and movable limit assembly is by limiting
Position block 4, movable bullet block 41 and spring part 42 form.This city city, which is gone through down by unit of plastic, is provided with compressible workpiece activity limit group
Part, since component is made of movable bullet block, spring and limit block part, the setting of limited block so that movable bullet block will not be because of strength
It is excessive and workpiece is caused to rupture, and when setting of movable bullet block can block injection molding, moulds because glass size is less than mould standard
Expect the situation of flash.
As one of preferred embodiment, which is characterized in that workpiece 1 is glass pieces.Being used due to glass pieces should
On the one hand technology cannot apply excessively high active force leads to its rupture, on the other hand can guarantee therefore plastics will not generate flash,
Improve production efficiency.
As one of preferred embodiment, which is characterized in that limited block 4 and movable bullet block 41 are arranged in lower die assembly
22 top and contact workpiece 1.So that movable bullet block effectively blocks the injection hole of workpiece 1 under this structure, flash is prevented.
The better embodiment of the utility model is illustrated above, but the utility model creation is not limited to
The embodiment, those skilled in the art can also make various etc. without departing from the spirit of the present invention
With modification or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
