The invention discloses the product ejecting structure of a kind of injection mould, including crescent shape mold insert, described crescent shape mold insert offers three thimble grooves；In described each thimble groove, jacking block moving up and down is installed；Described jacking block all extends vertically through mold insert；The top end face of described mold insert is provided with forming surface；The upper surface of described jacking block is concordant with the bottommost plane of forming surface；Described jacking block length is more than mold insert thickness；Described three jacking blocks are the position distribution of isosceles triangle.The product ejecting structure of the injection mould of the present invention, crescent shape product cavity bottom is provided with three jacking blocks, and position distribution is reasonable, effectively makes injecting products outward appearance reduce thimble vestige and thimble overlap.
Description
Technical field
The present invention relates to the technical field of structures of plastic cement products mould, particularly relate to the product ejecting structure of injection mould.
Background technology
Along with improving constantly of technology, the fast development of plastic cement products industry, the diversification structure of all kinds of plastic cement parts
Becoming increasingly complex, quality requirements is more and more strict, the highest to plastic cement products industry requirement, and competition is the fiercest,
How to ensure that similar plastic cement products occurs without exception in process of production, maximized guarantee Product processing is effective, stable
Production cycle.General injection mold is all by thimble, the product of injection formed is ejected die cavity, but the structure of thimble and position
It is distributed extremely important, thimble vestige and the thimble overlap situation of product can be badly influenced, since it is desired that according to different products,
Develop corresponding ejecting structure.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose a kind of effectively minimizing thimble vestige and top
The product ejecting structure of the injection mould of pin overlap.
The technical solution of the present invention is achieved in that the product ejecting structure of a kind of injection mould, including crescent shape
Mold insert, described crescent shape mold insert offers three thimble grooves；In described each thimble groove, jacking block moving up and down is installed；
Described jacking block all extends vertically through mold insert；It is provided with forming surface on the top end face of described mold insert；The upper surface of described jacking block and molding
The bottommost plane in face is concordant；Described jacking block length is more than mold insert thickness；Described three jacking blocks are that the position of isosceles triangle is divided
Cloth.
Preferably, described forming surface is the crescent shape that middle part is protruding, around becomes plane.
Preferably, one of them jacking block of described three jacking blocks is positioned at the middle part of crescent big circumference, two other jacking block
It is positioned at inner side two point of crescent small circumference.
Preferably, described three jacking blocks are the position distribution of equilateral triangle.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The product ejecting structure of the injection mould of the present invention, crescent shape product cavity bottom is provided with three jacking blocks, and position distribution is reasonable,
Can farthest make injecting products outward appearance reduce thimble vestige and thimble overlap, and be convenient to install, dismantle.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of the present invention；
Accompanying drawing 2 is the top view of the crescent shape mold insert of the present invention；
Wherein: 1, mold insert；2, thimble groove；3, jacking block；4, forming surface.
Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
The product ejecting structure of the injection mould of the present invention, as shown in accompanying drawing 1,2, including crescent shape mold insert 1, described crescent shape
Three thimble grooves 2 are offered on mold insert 1；In described each thimble groove 2, jacking block 3 moving up and down is installed；Described jacking block 3 is equal
Extend vertically through mold insert 1；It is provided with forming surface 4 on the top end face of described mold insert 1；The upper surface of described jacking block 3 and forming surface 4 are
Base plane is concordant；Described jacking block 3 length is more than mold insert 1 thickness；Described three jacking blocks 3 position distribution in isosceles triangle.
Further instruction, described forming surface 4 is the crescent shape that middle part is protruding, around becomes plane；Described three jacking blocks 3
One of them jacking block be positioned at the middle part of crescent big circumference, the inner side two that two other jacking block is positioned at crescent small circumference is most advanced and sophisticated
Portion.
Further instruction, described three jacking blocks 3 position distribution in equilateral triangle, when the central point of three jacking blocks connects
When becoming equilateral triangle, when ejecting, stress is the most uniform, can farthest ensure Product Precision.
The product ejecting structure of the injection mould of the present invention, crescent shape product cavity bottom is provided with three jacking blocks, position distribution
Rationally, can farthest make injecting products outward appearance reduce thimble vestige and thimble overlap, and be convenient to install, dismantle.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and is carried out, and can not limit the scope of the invention with this, all according to the present invention
The equivalence that spirit is made changes or modifies, and all should contain within the scope of the present invention.
