Abstract
The utility model discloses a locating mechanism of a precision plastic mould. The locating mechanism comprises an upper mould and a lower mould, wherein a moulding male mould and locating lugs are arranged at the bottom of the upper mould; a moulding female mould and locating grooves are formed at the top of the lower mould, wherein the moulding female mould is matched with the moulding male mould in shape, and the locating grooves are matched with the locating lugs in shape; a space between the moulding male mould and the moulding female mould is a cavity; bevels are formed between the moulding female mould and the locating grooves at the top of the lower mould; blowdown cavities are formed in a space between the bevels and the bottom of the upper mould; vent holes communicating the blowdown cavities with the outside air are formed in the locating lugs and are horn-shaped holes with diameters gradually increasing from outside to inside; telescopic locating columns are arranged at the bottoms of the locating lugs; locating slots are formed in the positions, corresponding to the locating columns, of the locating grooves. The locating mechanism has the beneficial effects that through improved design of the blowdown cavities and the vent holes of the mould, the redundant plastic melt can smoothly enter the blowdown cavities and venting is carried out more smoothly and thoroughly, thus being beneficial to moulding of plastic products and obtainment of relatively straight and upright right angles.
Description
Technical field
The utility model relates to a kind of detent mechanism of precision plastic rubber mould.
Background technology
When plastic mould is carried out to Precision Machining, need to locate accurately upper die and lower die, and add man-hour, sometimes also need to proofread and correct its setting angle.But existing mould positioning mechanism still cannot effectively be eliminated the deviation in position and angle when location.
Utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art, proposes a kind of detent mechanism of precision plastic rubber mould.
The technical solution adopted in the utility model is as follows:
A kind of detent mechanism of precision plastic rubber mould, by upper die and lower die, formed, patrix bottom is provided with forming convax mould and locating convex block, counterdie top be provided with the molding concave die of forming convax mould form fit and with the detent of locating convex block form fit, the space between forming convax mould and molding concave die is die cavity; Counterdie top is provided with inclined-plane between molding concave die and detent, and the gradient on described inclined-plane is 30 °, and the space between inclined-plane and patrix bottom forms blowdown chamber; On locating convex block, offer the steam vent that is communicated with blowdown chamber and outside air, described steam vent is the flared hole that aperture expands from outside to inside gradually; In locating convex block bottom, be provided with telescopic locating dowel, the position of the corresponding locating dowel of detent is provided with locating slot.
The beneficial effects of the utility model are, add locating dowel and locating slot, make upper and lower mould when location, and not only position is more accurate, and can, by regulating the height of locating dowel, realize the adjusting of orientation angle.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model mould.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the technical solution of the utility model is described further.
Referring to Fig. 1, the detent mechanism of precision plastic rubber mould, by patrix 1 and counterdie 2, formed, patrix bottom is provided with forming convax mould 11 and locating convex block 12, counterdie top be provided with the molding concave die 21 of forming convax mould form fit and with the detent 22 of locating convex block form fit, the space between forming convax mould and molding concave die is die cavity; Counterdie top is provided with inclined-plane between molding concave die and detent, and the gradient on described inclined-plane is 30 °, and the space between inclined-plane and patrix bottom forms blowdown chamber 3; On locating convex block, offer the steam vent 13 that is communicated with blowdown chamber and outside air, described steam vent is the flared hole that aperture expands from outside to inside gradually.In locating convex block bottom, be provided with telescopic locating dowel 14, the position of the corresponding locating dowel of detent is provided with locating slot 23.
During location, by locating dowel is aimed to locating slot, embed, can improve the precision of location; By regulating the height of both sides locating dowel, the angle that can install land area regulates.
To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
