Abstract
The invention discloses an injecting and molding mold positioning device which comprises a movable die, a fixed die, a positioning guiding column and a positioning guiding sleeve. The positioning guiding column is arranged on the movable die; the positioning guiding sleeve is arranged on the fixed die; the middle section of the positioning guiding column is shaped like a cone; the rear section of an inner hole of the positioning guiding sleeve is provided with a conical hole; when a gap between a cylinder on the front section of the positioning guiding column and the circular hole in the front section of an inner hole of the positioning guiding sleeve enlarges gradually due to long-time friction, the positioning guiding column and the positioning guiding sleeve are matched with each other closely due to the matching characteristic of the cone and the conical hole. Due to the implementation of the injecting and molding mold positioning device disclosed by the invention, the maintenance frequency of a mold is reduced, and the service life of the mold is prolonged greatly.
Description
Technical field
The present invention relates to the plastic mold manufacture technical field, especially a kind of injection mold positioner with positioning guide column and location guide pin bushing.
Background technology
At present in the injection machine mould, location when dynamic model and cover half matched moulds all is to realize by the location guide pin bushing that the positioning guide column insertion that is located on their central modules is located on another module, generally speaking, positioning guide column is cylindrical shape, the endoporus of location guide pin bushing is circular hole, insert the location guide pin bushing for the ease of positioning guide column, the gap that arranges between positioning guide column and the location guide pin bushing can not be too small; In addition, working of plastics of the every injection moulding of injection machine, positioning guide column on the injection mold dynamic model just pass in and out on the cover half the location guide pin bushing each once, often one working day the injection mould open-close mould reach hundreds of time even thousands of times, so just cause mutually friction between positioning guide column and the location guide pin bushing, the two gap constantly increases, and when the two gap reached certain value, problem of misalignment will appear in dynamic model and cover half matched moulds.Will inevitably there be following deficiency in existing this technical scheme for above-mentioned reasons: 1, positioning guide column and guide pin bushing gap, location are large, cause fixed half and moving half matched moulds position unstable, and the die cavity dislocation of dynamic model, cover half affects product quality, even produces defective work; 2, the wearing and tearing of positioning guide column and location guide pin bushing aggravate the positioning guide column that need more renew and locate guide pin bushing, also can cause cover half or dynamic model to damage when serious, and reduce die life.
Summary of the invention
The purpose of this invention is to provide a kind of injection mold positioner, this injection mold positioner causes the problem of injection mold die cavity dislocation, minimizing to repair a die the time after can solving positioning guide column and the increase of guide pin bushing gap, location, and greatly improved die life.
In order to address the above problem, the technical solution used in the present invention is:
This injection mold positioner comprises dynamic model, cover half, and is contained in positioning guide column and the location guide pin bushing that is contained on the cover half on the dynamic model, and described positioning guide column stage casing is cone, and described location guide pin bushing endoporus external port is conical bore.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, positioning guide column is cooperating of cylinder and circular hole with location guide pin bushing leading portion, back segment is cone and the cooperating of taper hole, because the characteristic that the back segment cone cooperates with taper hole will make cone cooperate with taper hole tightr, solved the problem of injection moulding die cavity dislocation after the leading portion wearing and tearing.
2, positioning guide column and location guide pin bushing can be because front end wearing and tearing or cover half, dynamic model do not damage to cause and repair a die, and the mold use life-span improves greatly.
Description of drawings

Positioning guide column and location guide pin bushing cooperated schematic diagram when Fig. 2 was the injection machine mould die sinking.
Fig. 3 is location guide pin bushing front view.
Fig. 4 is the positioning guide column front view.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing embodiment:
Injection mold positioner shown in Figure 1, it is at dynamic model 2 four positioning guide column 4 to be installed, corresponding to the positioning guide column 4 on the dynamic model 2 is corresponding on cover half 1 four location guide pin bushings 3 are housed, the stage casing of each positioning guide column 4, namely the D section of the root of close dynamic model 2 is cone, and B section of each location guide pin bushing 3 interior outer end of hole is conical bore.
During injection mould closing, as shown in Figure 1, positioning guide column 4 enters in the guide pin bushing 3 of location, locates A face on the guide pin bushing 3, B face this moment and cooperates with C face, D face on the positioning guide column 4 respectively; During the injection machine mould die sinking, as shown in Figure 2, the A face of location on the guide pin bushing 3, B face separate with C face, D face on the positioning guide column 4 respectively; Behind the working of plastics of mould production some, C face, D face on A face, B face and the positioning guide column 4 on the guide pin bushing 3 of location all can wear and tear, this moment, A face and C face gap were strengthened, the B face can't make the gap between them strengthen with the characteristic that the D face cooperates with taper hole owing to cone, just can make the D face more be adjacent to the B face, in this case, marked change can not occur in the location of whole injection mold, and the mold use life-span is improved.
