Abstract
The invention discloses an improved guiding and positioning pin for an injection mold. The modified guiding and positioning pin comprises a mold cavity plate and a core plate, wherein a positioning sleeve is mounted in the cavity plate, and a positioning pin is mounted in the core plate; a straight surface guiding hole and a conical surface locking hole are formed in the positioning sleeve, a straight surface guiding rod and a conical surface locking block are arranged on the positioning pin, the straight surface guiding rod and the straight surface guiding hole are matched, and the conical surface locking block and the conical surface locking hole are matched. Through the adoption of the scheme disclosed by the invention, two functions of straight surface guiding and conical surface positioning are combined into one component, so that double functions of guiding and positioning between two moving components of the injection mold are realized, the modified guiding and positioning pin is simple in structure, convenient to process and low in cost, the internal structure of the mold is simplified, and the investment cost of the mold is reduced.
Description
Technical field
The present invention relates to a kind of injection mold modified guide positioning pin, be mainly used in the location needed between accurate guiding movement parts.
Background technology
In the guide-localization of prior art between injection mold moving component, several mode such as general employing guide pillar guide pin bushing, straight flange lock (facing lock directly), conical-surface positioning pin, contour localization block and conical surface Shu Tong, but this severally guide locating device providedly all can only play single effect.And in actual injection mold; often can run into active and inactive mold die joint, that the face gradient of wearing is touched in active and inactive mold core pillow position etc. is too little; if only use above a kind of guide-localization mode; active and inactive mold die joint, active and inactive mold core pillow position etc. then can be caused to touch the face of wearing first contact; active and inactive mold die joint, active and inactive mold core pillow position etc. is touched the face of wearing and is is first worn and torn, and easily causes moulding to produce overlap.Combinationally use according to above several guide-localization mode, then complicated mould, improves cost.
Summary of the invention
The object of the invention is the shortcoming in order to overcome prior art, there is provided between a kind of injection mold two moving component and can accurately lead, can accurately locate again, improve mould and die accuracy, simplify mold structure, reduce the injection mold modified guide positioning pin of die cost investment.
The technical scheme of injection mold modified guide positioning pin of the present invention is: comprise cavity board and core plate, in described cavity plate, positioning sleeve is installed, in described core plate, alignment pin is installed, it is characterized in that arranging in described positioning sleeve facing guide hole and conical surface lockhole directly, described alignment pin is arranged and faces guide rod and conical surface lock dog directly, face guide rod directly and face guide hole directly and match, conical surface lock dog matches with conical surface lockhole.
Injection mold modified guide positioning pin of the present invention, when injection mould closing, core plate and cavity plate are closed up, faced guide rod before this directly to stretch into and face directly in guide hole, facing guide rod directly with the gap facing guide hole directly is generally 0-0.04mm, therefore, and can accurate the closing up of guidance type central layer and cavity plate.After core plate and cavity plate are brought together into certain distance, conical surface lock dog matches with conical surface lockhole, and the accurate location of finishing type central layer and cavity plate, completes injection mould closing.This programme will face guiding directly and the conical surface is located two kinds of functions and is attached in an assembly, achieve between injection mold two moving component lead, location dual-use function, structure is simple, and easy to process, cost is low, simplifies mould inside structure, reduction mould cost of investment.
Injection mold modified guide positioning pin of the present invention, arrange step in described cavity plate, positioning sleeve is fixed on step, has had step, and positioning sleeve is fixing reliable.Arrange cushion block in described core plate, cushion block is fixed by screw and alignment pin, and had cushion block, alignment pin is easy for installation, fixed.The conical surface gradient a of described conical surface lockhole is 40 °, and the conical surface gradient of conical surface lock dog is consistent with the conical surface gradient a of conical surface lockhole, and 40 ° of conical surface location are more accurate.Described facing directly on guide rod is shaped with oil-way, can removal of lubricant, runs smooth and easy during guiding.
