Description
Technical field
The present invention relates to injection mold field, especially a kind of automobile grills mould directly pushes up the bullet roof construction of tunnel gate.
Background technology
With the continuous improvement that people are required automobile appearance, grid product moulding becomes increasingly complex, product appearance requirement
Compare it is high, can not have after injection molding gas trace, cold burden, shrink the defects of, in order to meet appearance requirement, with reference to grid product horizontal stripe
The structure of shape, mould enter glue mode by the way of glue is entered in latent rear mold, preferable product appearance can be obtained, in rear mold of hiding
Ramp-roof structure ability ejecting product can only often be used and pour intraoral sizing material by entering the mode of glue, but having will also assemble on grid
Ornamental strip, therefore have many pilot holes on grid horizontal bar, and pilot hole can cause that ramp-roof structure can not be used on mould too much, therefore
Can cause to pour intraoral sizing material to be stripped.
The content of the invention
The shortcomings that it is an object of the invention to overcome prior art, there is provided a kind of automobile grills mould directly pushes up tunnel gate

There is the die cavity for forming cavity portion side face and being connected with cast gate to be formed for the push rod that jacking block moves up and down, the upper end of the straight jacking block
Portion, the side of the straight jacking block offer the first gate part to form gate portions side face, and the rear cavity is matched somebody with somebody with straight jacking block
The second gate part to form gate portions side face is offered on conjunction face, the rear mold also includes being used to that intraoral sizing material ejection will to be poured
Ejecting structure outside first gate part, it is described that the pilot hole coordinated with the ejecting structure, the ejection are directly offered on jacking block
Structure include being fixed on the locating part in pilot hole and extended laterally, the ejection piece that can be moved along the locating part length direction,
And the spring part on locating part is set in, the ejection piece has the first end coordinated with rear cavity and relative with first end set
The second end put, the first end of the ejection piece offers is collectively forming the cast gate with the first gate part and the second gate part
3rd gate part, the second end and the spring part of the ejection piece offset.
By above technical scheme, the side that first gate part is offered on the straight jacking block is the first of straight jacking block
Side, the end face of the first side of the straight jacking block take the form of inclined plane.
By above technical scheme, the pilot hole is through the first side of the straight jacking block, and the pilot hole is along outside straight jacking block
Portion to straight jacking block internal direction includes being sequentially connected and first paragraph that diameter is sequentially reduced, second segment and the 3rd section, described spacing
One end of part is fixed in the 3rd section of pilot hole, the other end is extended in the first paragraph of pilot hole and has outwardly protruding limit
Position portion, the spring part offer pilot hole, the pilot hole quilt in the second segment of the pilot hole on the ejection piece
It is divided into the first paragraph coordinated with the limiting section and the second segment coordinated with locating part, the pilot hole first paragraph and second
The interface of section is configured to confined planes.
By above technical scheme, the 3rd section of the locating part and the pilot hole is connected through a screw thread.
Prior art is contrasted, beneficial features of the invention are：The automobile grills mould directly pushes up the bullet roof construction of tunnel gate,
After preceding mould and rear mold die sinking, straight jacking block is ejected outside rear cavity in the presence of push rod, first end and the rear cavity point of ejection piece
From when, in the presence of spring part, ejection piece moves towards outside pilot hole, so as to pour intraoral sizing material out of first gate part
Ejection, avoid pouring intraoral sizing material and remain in straight top, improve production efficiency and stability is good.
