The utility model content
To water oral-lateral and product in the prior art injection mold and eject side and lay respectively on the fixed half and moving half of mould in order to solve; Thimble ejects product; The thimble seal on the appearance of product, occurs, influence the problem of product appearance quality greatly, it is a kind of simple in structure that the utility model provides; Water oral-lateral and product and eject side and be positioned at cover half one side, can eliminate the injection mold of thimble seal on the Surface Appearance.
In order to address the above problem, the technical scheme that the utility model is taked is:
A kind of injection mold comprises dynamic mould fixing plate, cover half fixed head, dynamic model pin, cover half pin, above dynamic mould fixing plate, is provided with the dynamic model pin; Below the cover half fixed head, be provided with the cover half pin; It is characterized in that also comprising: moving platen, solid plate, core rod, injection molding channel, ejector retainner plate, thimble, underfooting side is provided with solid plate at cover half, above the dynamic model pin, is provided with moving platen; Moving platen is provided with core rod; On the cover half fixed head, offer the injection hole of injection molding channel, injection molding channel is connected with core rod through cover half fixed head, cover half pin, solid plate successively, below the cover half fixed head, be provided with ejector retainner plate between the two cover half pin; Below ejector retainner plate, be provided with thimble, thimble passes solid plate and is positioned at the core rod top.
Aforesaid a kind of injection mold; It is characterized in that: said injection molding channel comprises sprue and runner; On moving platen, be provided with two core rod is arranged; Said sprue gets in the solid plate through cover half fixed head and cover half pin successively, and is connected with the runner of both sides, and the runner of said both sides is connected with the core rod of respective side respectively.
Aforesaid a kind of injection mold is characterized in that: above the cover half fixed head, be provided with the cover half thermal insulation board, said injection hole also passes the cover half thermal insulation board.
Aforesaid a kind of injection mold is characterized in that: below dynamic mould fixing plate, be provided with the dynamic model thermal insulation board.
Aforesaid a kind of injection mold is characterized in that: the arranged outside of injection hole have one enclose positioning action locating ring.
Aforesaid a kind of injection mold is characterized in that: said dynamic mould fixing plate and cover half fixed head adopt arc, and four angles of said dynamic mould fixing plate and cover half fixed head are not wedge angles.
The beneficial effect of the utility model is: the injection mold of the utility model will water oral-lateral and product and eject side and be positioned at cover half one side; On Surface Appearance, just do not have liftout attachment like this and advance adhesive dispenser; Can eliminate the thimble seal on the Surface Appearance, the product appearance quality improves greatly.Do not have wedge angle on the mould simultaneously, be difficult for the scratch operating personnel, safe and reliable.
