The cow glue powder is defined jointly in the bottom of closing part point.
A kind of injection mold enters plastic structure, including mold insert, and the rear cavity of the injection mold has mold insert mounting hole, institute
State mold insert and insert the mold insert mounting hole to form cow glue powder, the rear cavity has upper in the top of the mold insert mounting hole
Enclosure portion is held, so that the mold insert mounting hole turns into mold insert installing blind, the mold insert is inserted in the mold insert installing blind,
The cow glue powder is formed between the bottom of the upper end closed part and the top of the mold insert, the product to be formed
The outward appearance of lateral wall is accordingly defined by the madial wall of the upper end closed part.
Further：
Arcuate recess is formed on the top of the mold insert, and arch projection, the arch are formed on the bottom of the upper end closed part
Shape is recessed and the arch projection is oppositely arranged and defines the cow glue powder jointly.
The mold insert is single mold insert.
The mold insert is that two mold insert components are half-and-half spliced, the top of described two mold insert components and the upper end seal
The cow glue powder is defined jointly in the bottom of closing part point.
The beneficial effects of the utility model：
The utility model does the mold insert for forming cow glue powder the form of cecutiency mold insert, avoids producing on Surface Appearance
Clamp, solve the problems, such as that product appearance has clamp on corresponding common cow glue powder position.
Wearing class looking products use injection mold of the present utility model, can fundamentally solve common cow glue powder position
The shortcomings that mold insert line being present and influenceing outward appearance, so as to meet the high request to outward appearance.The cast gate for entering plastic structure of the injection mold
Position is hidden, will not cause bad order, can fully meet to shape volume production and harsh exterior quality requirement.
