Background technology
Plastic injection mould is the instrument producing plastic products, and application widely.In plastic products injection moulding, in order to meet the needs of moulding process, need to control the opening sequence of mould die joint and the demoulding order of product, for this reason, dealer needs the ejecting mechanism designing various mould of plastics, for ejecting product stage by stage.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, the Delayed ejection mechanism of the injection mold of reliable in action.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of Delayed ejection mechanism of injection mold, comprises hot runner manifold, cope match-plate pattern, mother module core, male die core, cavity plate, lower bolster, square iron, base plate, slide block bundle plate, slide block, sliding block spring, Angle Pin fixed block, Angle Pin; Described hot runner manifold, cope match-plate pattern, mother module core are fixedly connected sequentially together; Described cavity plate is fixed on lower bolster, and male die core is fixed in lower bolster, and the contact surface of male die core and mother module core is die joint; Described lower bolster is fixed on base plate by square iron; Described slide block slips in mother module core, and die cavity is stretched in the inner of slide block, and slide block bundle plate to be fixed on mother module core and to lean with slide block outer end, and sliding block spring is arranged between slide block and lower bolster; Described Angle Pin fixed block is fixed on mother module core, and the upper end of Angle Pin is fixed on Angle Pin fixed block, and the lower end of Angle Pin is stretched in the slanting guide pillar hole of the outside of slide block; Also comprise upper plate, lower roof plate, flat thimble, dome pin, postpone thimble; Described upper plate and lower roof plate be fixed together and both together activity be nested with between lower bolster and base plate; The upper end of described flat thimble penetrates lower bolster and can stretch into die cavity, and flat thimble lower end is fixedly set in upper plate; The upper end of described dome pin penetrates lower bolster and can lean with cavity plate, the activity of dome pin is set in upper plate and the lower surface of dome pin and leans with delay thimble upper surface, lower roof plate offers and postpones the shoulder hole of thimble for wearing, to postpone in shoulder hole that thimble activity is set in lower roof plate and postpone the cascaded surface of countersunk head and the cascaded surface of shoulder hole on thimble to lean.
After adopting such scheme, because the utility model is provided with delay thimble, the activity of dome pin is set in upper plate and the lower surface of dome pin and leans with delay thimble upper surface, utilize the delay structure postponing thimble, make to postpone thimble and can postpone ejection dome pin, thus meet the needs of ejecting product stage by stage, have that structure is simple, the advantage of reliable in action.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model is a kind of Delayed ejection mechanism of injection mold, comprises hot runner manifold 1, cope match-plate pattern 2, mother module core 3, male die core 4, cavity plate 5, lower bolster 6, square iron 7, base plate 8, postpones thimble 9, slide block bundle plate 10, slide block 11, sliding block spring 12, Angle Pin fixed block 13, Angle Pin 14, upper plate 15, lower roof plate 16, flat thimble 17, dome pin 18.
Described hot runner manifold 1, cope match-plate pattern 2, mother module core 3 are fixedly connected sequentially together.Described cavity plate 5 is fixed on lower bolster 2, and male die core 4 is fixed in lower bolster 6, and male die core 4 is die joint with the contact surface of both mother module cores 3.
Described lower bolster 6 is fixed on base plate 8 by square iron 7.
Described slide block 11 slips in mother module core 3, and die cavity is stretched in the inner of slide block 11, and slide block bundle plate 10 to be fixed on mother module core 3 and to lean with slide block 11 outer end, and sliding block spring 12 is arranged between slide block 11 and lower bolster 6; Described Angle Pin fixed block 13 is fixed on mother module core 3, and the upper end of Angle Pin 14 is fixed on Angle Pin fixed block 13, and the lower end of Angle Pin 14 is stretched in the slanting guide pillar hole of the outside of slide block 11.
Described upper top 15 plate and lower roof plate 16 are fixed together and both are together in the movable space be nested with between lower bolster 6 and base plate 8, and the height in this space is highly determined by square iron 7; The upper end of described flat thimble 17 penetrates lower bolster 6 and can stretch into die cavity, and flat thimble 17 lower end is fixedly set in upper plate 15; The upper end of described dome pin 18 penetrates lower bolster 2 and can lean with cavity plate 5, dome pin 18 activity is set in the upper plate 15 and lower surface of dome pin 18 and leans with delay thimble 9 upper surface, lower roof plate 16 offers and postpones the shoulder hole 161 of thimble 9 for wearing, to postpone in shoulder hole 161 that thimble 9 activity is set in lower roof plate 16 and postpone the cascaded surface of countersunk head 91 and the cascaded surface of shoulder hole 161 on thimble 9 to lean.
Operation principle of the present utility model:
1, die sinking: carry out slide block 11 in mould female counterpart hot runner manifold 1, cope match-plate pattern 2, mother module core 3, male die core 4 die sinking process at injection board and complete slide block die sinking action under the effect of Angle Pin 14.
2, eject: under the rod effect of board top, upper plate 15 and lower roof plate 16 drive flat thimble 17 and justify holder pin 18 and ejecting product, the Distance geometry top rod move distance of flat thimble 17 motion is identical in this process, dome pin 18 bottom surface contacts with delay thimble 9 end face, and when top rod ejects, dome pin 18 keeps synchronous with delay thimble 9 all the time and remains static until ejection stroke drives more than lower roof plate during 15mm 16 postpones thimble 9 and continue to eject under the resistance of product and hole sidewall; Now dome pin 18 just achieves with flat thimble 17 and synchronously ejects (in structure, the position of flat thimble 17 does not directly contact with product apart from being also necessary for 15mm to the product needing to eject), and this process is delayed ejection.
3, return: liftout plate drives flat thimble 17 and dome pin 18 synchronously back to reset condition under the rod pull bar effect of top, this process mainly dome pin 18 utilizes the delay head-to-foot plate 8 of thimble 9 and carries out position correction, and the length therefore postponing thimble 9 must be equal with the thickness of lower roof plate 16+ rubbish nail.
Illustrate: all have need male and female slide block shaping and slide block bottom surface uses the utility model delayed ejection structure better can simplify mould structure and cost-saving under having thimble situation.
Emphasis of the present utility model is just: be provided with delay thimble.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
