It is CN104690886A that State Intellectual Property Office discloses publication number on June 10th, 2015, patent name is a kind of patent of injection mold, the present invention includes dynamic mould fixing plate and ejector pin retaining plate, and be arranged on the push rod installing plate of ejector pin retaining plate upper surface, and the dynamic model backing plate be arranged on above push rod installing plate, moving platen and push pedal, and the solid plate be arranged on above push pedal and cover half fixed head, and run through the sprue bush of solid plate and cover half fixed head, and run through solid plate, the guide pillar of push pedal and moving platen, guide pin bushing and release link, and be arranged on the spring of release link surrounding, and sprue puller, core fixed bar, nut is nested with push pedal, and be arranged in push pedal, screw in release link and core, and the die cavity be arranged on above core is nested.Due to described mould, that push pedal and the part that dynamic model inserts contacts are provided with push pedal is nested, facilitate the adjustment of mould parts, replacing, in addition, between the nested and dynamic model inserts of push pedal, adopt the method for cone match, the wearing and tearing of mould when matched moulds can be reduced, improve the mold use life-span.
The technical scheme of above-mentioned patent, when the special-shaped product noted is taken out in the demoulding, easily makes deformation of products, even damages product.
Utility model content
The purpose of this utility model is to provide a kind of form and position tolerance and the dimensional tolerance that ensure that part, improves the mould preventing deformation of products of the qualification rate of product.
For achieving the above object, the technical scheme that the utility model adopts is:
Prevent the mould of deformation of products, comprise die cavity and core, described core is provided with wedge shape groove, the prism of described wedge shape groove is provided with step plane, described step plane parallels with the another side of wedge shape groove, suitable slanted kicking block is provided with in described wedge shape groove, laterally stairstepping through hole is provided with in described slanted kicking block, staged push rod and spring is provided with in described stairstepping through hole, described spring housing is contained on staged push rod, the top, one end of spring is pressed on the step surface of staged push rod, other end top is pressed on the step surface of stairstepping through hole, when the oblique movement of slanted kicking block, depart from wedge shape groove when noting product section, the stub end top of staged push rod to be pressed in step plane and along step planar slide, the little head end of staged push rod keeps note product section top to the institute in wedge shape groove and presses and support.
Further, also comprise B plate and A plate, described core is fixed on B plate, and described die cavity is fixed on A plate.
Further, also comprise push rod and multiple thimble, the upper end of described each thimble is upwards passed and is pushed up and is pressed on noted product from core, and the other end of each thimble is fixed on thimble fixed head, the top, upper end of described push rod is pressed on described slanted kicking block, and the other end is fixed on thimble fixed head.
The beneficial effects of the utility model: owing to being provided with staged push rod and spring in the stairstepping through hole in slanted kicking block, except the original side core-pulling function of reservation, also add the function of top pressure and support product, expand the scope of application of oblique top, ensure that form and position tolerance and the dimensional tolerance of part, improve the qualification rate of product.In addition, if transformation the utility model being applied to the outer side core-pulling of slide block is more practical, so do not need to adjust injector parameter or artificial post processing just can ensure the precision of its product.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing at the place of A shown in Fig. 1.
In figure: 1, die cavity; 2, core; 3, wedge shape groove; 4, step plane; 5, another side; 6, slanted kicking block; 7, stairstepping through hole; 8, staged push rod; 9, spring; 10, note product section; 11, B plate; 12, A plate; 13, push rod; 14, thimble; 15, note product; 16, thimble fixed head.
Detailed description of the invention
As shown in Figure 1, a kind of mould preventing deformation of products, comprise die cavity 1 and core 2, also comprise B plate 11 and A plate 12, described core 2 is fixed on B plate 11, described die cavity 1 is fixed on A plate 12, also comprise push rod 13 and multiple thimble 14, the upper end of described each thimble 14 is upwards passed and is pushed up and is pressed on noted product 15 from core 2, the other end of each thimble 14 is fixed on thimble fixed head 16, the top, upper end of described push rod 13 is pressed on described slanted kicking block 6, and the other end is fixed on thimble fixed head 16.
As shown in Figure 2, described core 2 is provided with wedge shape groove 3, the prism of described wedge shape groove 3 is provided with step plane 4, described step plane 4 parallels with the another side 5 of wedge shape groove, suitable slanted kicking block 6 is provided with in described wedge shape groove 3, laterally stairstepping through hole 7 is provided with in described slanted kicking block 6, staged push rod 8 and spring 9 is provided with in described stairstepping through hole 7, described spring 9 is sleeved on staged push rod 8, the top, one end of spring 9 is pressed on the step surface of staged push rod 8, other end top is pressed on the step surface of stairstepping through hole 7, when the oblique movement of slanted kicking block 6, depart from wedge shape groove 3 when noting product section 10, the stub end top of staged push rod 8 to be pressed in step plane 4 and to slide along step plane 4, the little head end of staged push rod 8 keeps note product section 10 to the institute in wedge shape groove 3 and pushes up and press and support.
Operation principle: the utility model except for prevent deformation of products or fracture except, also can play the effect of ejecting product, when needing to eject the product of the comparatively large or this type that side wall thickness is less of lateralarea, be the dimensional tolerance value being difficult to ensure the indeformable and product of product by existing method.And use the utility model, as long as increase staged push rod and spring, and with staged push rod with the use of step plane, when ejecting, promote slanted kicking block 6 promote together with thimble 14 note product.Meanwhile, slanted kicking block 6 completes to left movement action of loosing core along wedge shape groove 3 in the process ejected, and staged push rod is not moved to the left under the effect of step plane, forms relative motion with slanted kicking block 6, thus reaches the effect ejecting noted product section 10.This effectively prevents slanted kicking block when mobile, product has certain package power to slanted kicking block and drags bad product.As can be seen here, product can disposablely eject by this staged push rod smoothly, slanted kicking block with note product section 10 and depart from smoothly.
The above is preferred embodiment of the present utility model; certainly the interest field of the utility model can not be limited with this; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or equivalent replacement, do not depart from the protection domain of technical solutions of the utility model.
