Inclined guide pillar 11 is provided on the fixed clamping plate 1, the inclined hole opened up on the inclined guide pillar 11 and slide 12 slides Connection, and the slide 12 is then slidably connected in B plate 9, one end of the slide 12 is provided with horizontal slider 13, and level is sliding The end of block 13 is inserted into type chamber in molding, and resetting block 14, the resetting block 14 are additionally provided on fixed clamping plate 1 Bottom be provided with reset inclined-plane 15, be then provided on slide 12 with it is described reset inclined-plane 15 match driving inclined-plane 16,
The top of the dynamic model backing plate 8 is fixedly connected with multiple guide pads 17, and the longitudinal direction of 17 upper half of guide pad is disconnected Face is in isosceles triangle, slidably connects inner slide 18 respectively in the two sides on 17 top of guide pad, the inner slide 18 passes through T shape Raised line is slidably connected with the T-slot being provided on guide pad 17, and the top of the inner slide 18 is inserted into molding In type chamber,
Ejector spring bar 19 is additionally provided between bottom needle plate 5 and B plate 9.
The utility model compared with the existing technology, has the advantages that
The machine with the mold for first pulling out side core-pulling mechanism, in addition to utilizing the inclined guide pillar and sliding block that match of this kind of structure type Structure realizes except horizontal side core-pulling that it is interior to drive more sets to be arranged in pairs to also use the guide pad of multiple special constructions Sliding block movement, after the movement of these inner slides, can by there are the positions at back-off structure to allow out on product, thus allow be equipped with it is more The product of a back-off structure can be demoulded swimmingly.This kind of mold can disposably to being operated at multiple back-off structures, The time of die sinking is greatly saved, to improve work efficiency.And its manufacture craft is simple, and manufacturing cost is cheap, because This is it may be said that it has a variety of advantages, and particularly suitable for promoting and applying in the art, market prospects are very wide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is the portion the A enlarged drawing in Fig. 1.
Fig. 3 is the B direction view of Fig. 1.
Specific embodiment
Below in conjunction with Detailed description of the invention specific embodiment of the present utility model.As shown in Figure 1, Figure 2, Figure 3 shows: one kind has The mold of side core-pulling mechanism is first pulled out, it includes fixed clamping plate 1, and the lower section of the fixed clamping plate 1 is provided with A plate 2, in the A plate 2 It is provided with fixed die insert 3, the mold further includes moving clamping plate 4, and the moving clamping plate 4 has been sequentially arranged above bottom needle plate 5 and face needle plate 6, while square iron 7 is additionally provided on moving clamping plate 4, the top of square iron 7 is provided with dynamic model backing plate 8, the dynamic model pad It is provided with B plate 9 above plate 8, moving die insert 10 is provided in the B plate 9, the fixed die insert 3 and moving die insert 10 can The shape forming cavity in molding,
Inclined guide pillar 11 is provided on the fixed clamping plate 1, the inclined hole opened up on the inclined guide pillar 11 and slide 12 slides Connection, and the slide 12 is then slidably connected in B plate 9, one end of the slide 12 is provided with horizontal slider 13, and level is sliding The end of block 13 is inserted into type chamber in molding, and resetting block 14, the resetting block 14 are additionally provided on fixed clamping plate 1 Bottom be provided with reset inclined-plane 15, be then provided on slide 12 with it is described reset inclined-plane 15 match driving inclined-plane 16,
The top of the dynamic model backing plate 8 is fixedly connected with multiple guide pads 17, and the longitudinal direction of 17 upper half of guide pad is disconnected Face is in isosceles triangle, slidably connects inner slide 18 respectively in the two sides on 17 top of guide pad, the inner slide 18 passes through T shape Raised line is slidably connected with the T-slot being provided on guide pad 17, and the top of the inner slide 18 is inserted into molding In type chamber,
Ejector spring bar 19 is additionally provided between bottom needle plate 5 and B plate 9.
The course of work with the mold for first pulling out side core-pulling mechanism is as follows: behind cover half part and dynamic model part molding, Material is perfused into type chamber in molding machine, and after material solidification forming, dynamic model part downlink, molding product is exposed in air,
During dynamic model part downlink, inclined guide pillar 11 can be sliding by inclined hole with inclined guide pillar 11 relative to 9 uplink of B plate The slide 12 of dynamic connection then can the horizontal movement in B plate 9, and then the end of horizontal slider 13 is pulled to extract out from type chamber, realized Core pulling action;(when molding, under the action of resetting inclined-plane 15 and driving inclined-plane 16, slide 12 will drive 13 weight of horizontal slider again It is newly inserted into type chamber)
After die sinking, ejection axis drives bottom needle plate 5 and face needle plate 6 to move upwards together, and then ejector spring bar 19 is driven to push up B plate 9 move upwards, since dynamic model backing plate 8 cannot move upwards, B plate 9 can be moved upwards relative to dynamic model backing plate 8, i.e., All guide pads 17 can all be moved downward relative to B plate 9, due to the upper half of guide pad 17 be gradually collapse it is skewed, Therefore when guide pad 17 moves downward, the inner slide 18 being slidably connected therewith can be under the action of its inclined outer surface, court It is moved to the direction of 17 central axes of guide pad, inner slides 18 all so just can be all partially separated with the back-off of product, then Mandril can swimmingly eject product from moving die insert 10, realize the demoulding of product.
