Abstract
The utility model is related to the parting structure Curve guide impeller technical fields of injection mold, disclose a kind of improved structure for easily walking batch cutting edge of a knife or a sword mold parting, rear mold including mold and preceding mould, the face at die joint contacts rear mold with preceding mould, die joint constitutes acute angle under die joint and rear mold on the preceding mould, sealing face is machined on die joint, the sealing face length is 12-15 centimetres, the difference in height of preceding mould and rear mold at sealing face is 0.03-0.05 millimeters, cavity of the sealing face ring around mold, sealing face is closed loop shape, sealing face is process under rear mold on die joint, die joint is handled by mirror finish under die joint and rear mold on the preceding mould.The present apparatus to die joint by carrying out small improvement, it is designed using light grade sealing face formula, in conjunction with the slight precompressed of injection molding machine, the flatness error due to processing can effectively be improved, cause die joint actually sealing and graphics to have slight gap, batch cutting edge of a knife or a sword phenomenon is had away for the few plastic mould of excessive glue value.
Description
Technical field
The utility model is related to the parting structure Curve guide impeller technical fields of injection mold, easily walk to criticize more particularly to one kind
The improved structure of cutting edge of a knife or a sword mold parting.
Background technology
In the prior art, mould can be fully mated before and after usually we design the die joint of mold, but due to adding
The flatness error of work can cause die joint actually sealing and three dimensional design figure to have slight gap, few for excessive glue value
Plastic mould has away batch cutting edge of a knife or a sword phenomenon, and the bad order of product, severe patient is made to criticize cutting edge of a knife or a sword and can cut, pierce through other objects, influence to produce
The quality of product especially increases product following process treatment process.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of improvement for easily walking batch cutting edge of a knife or a sword mold parting
Structure, the structure design is simple, and can effectively improve various injection molds walks batch cutting edge of a knife or a sword phenomenon, to ensure injecting products
Presentation quality.
In order to achieve the above object, the technical solution adopted in the utility model is：It is a kind of easily to walk changing for batch cutting edge of a knife or a sword mold parting
Into structure, including the rear mold of mold and preceding mould, the face at die joint contacts rear mold with preceding mould, and die joint is with after on the preceding mould
Die joint constitutes acute angle under mould, and sealing face is machined on die joint, and sealing face length is 12-15 centimetres, and preceding mould is with after
Difference in height of the mould at sealing face is 0.03-0.05 millimeters.
Further, cavity of the sealing face ring as described above around mold.
Further, sealing face as described above is process under rear mold on die joint.
Further, die joint is handled by mirror finish under die joint and rear mold on mould before as described above.
Further, sealing face as described above is closed loop shape.
Compared with prior art, the utility model has the beneficial effects that：The present apparatus is adopted by carrying out small improvement to die joint
It is designed with light grade sealing face formula, in conjunction with the slight precompressed of injection molding machine, can effectively improve the flatness error due to processing,
Die joint actually sealing and graphics is caused to have slight gap, it is existing to have away batch cutting edge of a knife or a sword for the few plastic mould of excessive glue value
As reducing subsequent machining removal batch cutting edge of a knife or a sword phenomenon.

Specific implementation mode
Be described in detail with reference to attached drawing with reference to embodiment, so as to the technical characteristics of the utility model and advantage into
Row deeper into annotation.
As shown in Figs 1-4, a kind of improved structure for easily walking batch cutting edge of a knife or a sword mold parting of the utility model, includes the rear mold of mold
1 and preceding mould 2, rear mold 1 contacted in face at die joint 4 with preceding mould 2,1 time die joint of die joint and rear mold is constituted on the preceding mould 2
Acute angle is machined with sealing face 5 on die joint 4, and 5 length of the sealing face is 12-15 centimetres, and preceding mould 2 and rear mold 1 are in sealing face
Difference in height at 5 is 0.03-0.05 millimeters, and above-mentioned parameter is the empirical data summarized in actual production process, reduces finishing
Difficulty and reduction design improve variable quantity.
Further, the sealing face 5 injects sizing material 3 in cavity, sealing face 5 is under rear mold 1 around the cavity of mold
It is process on die joint, while the 4 normal parting of die joint of preceding mould 2 and design need not be modified, the sealing face 5
For closed loop shape, the overall appearance quality of injecting products is protected.
Further, 1 time die joint of die joint and rear mold is handled by mirror finish on the preceding mould 2, which can
To improve the service life of mold.
In utility model device, die joint 4 and sealing face 5 are professional art used in mold design and processing and manufacturing
Language, mirror finish processing is the prior art or material, and affiliated technical staff is according to required product type and specification, Ke Yizhi
It connects and buys or have made to order from market.
Clear, complete description is carried out to the utility model by the technical solution in above example, it is clear that described
Embodiment be the utility model part embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
