CN203472006U - Right angle moulding precision plastic mould - Google Patents

Abstract

The utility model discloses a right angle moulding precision plastic mould. The right angle moulding precision plastic mould comprises an upper mould and a lower mould, wherein a moulding male mould with right-angle edges 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 and have slant angles of 30 degrees; 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. The right angle moulding precision plastic mould 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

The precision plastic rubber mould of a kind of right angle moulding

Technical field

The utility model relates to a kind of precision plastic rubber mould.

Background technology

Due to the needs of assembling, the right angle that some precision plastic rubber product requirements are comparatively straight and upright, and traditional plastic rubber mold structure is comparatively complicated, when the product at processing right angle, often cannot reach required precision.

Utility model content

The purpose of this utility model is, overcomes the deficiencies in the prior art, proposes the precision plastic rubber mould of a kind of right angle moulding.

The technical solution adopted in the utility model is as follows:

The precision plastic rubber mould of a kind of right angle moulding, by upper die and lower die, formed, patrix bottom is provided with forming convax mould and the locating convex block of square edge, 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.

The beneficial effects of the utility model are, improvement design has been carried out in the blowdown chamber of mould and steam vent, make unnecessary plastic cement melt can enter smoothly blowdown chamber, and more smooth and easy and thorough during exhaust, be conducive to the moulding of plastic cement products and obtain comparatively straight and upright right 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 precision plastic rubber mould of right angle moulding, by patrix 1 and counterdie 2, formed, patrix bottom is provided with forming convax mould 11 and the locating convex block 12 of square edge, 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.

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.
