Abstract
The utility model discloses a double-sliding-block secondary core-pulling mechanism of a cylindrical lamp shell die-casting die. The double-sliding-block secondary core-pulling mechanism is characterized by comprising an inner sliding block, an outer sliding block, a bending pin, a fixed die, an oil cylinder, a sliding block base and a moving die. The inner sliding block is a product inner hole core which is matched with an inner hole of the outer sliding block and can move backwards. The outer sliding block is a product shape end face core and is fixed to the sliding block base. The bending pin is fixed to the fixed die and can shift the inner sliding block. The fixed die is a fixed part of the die-casting die and a main structure of the die-casting die. The oil cylinder is fixed to the side face of the moving die and drives the sliding block base to move forwards and backwards in operation. The sliding block base is connected with the oil cylinder and moves in a sliding groove of the moving die. Compared with the prior art, the double-sliding-block secondary core-pulling mechanism has the advantages that by the adoption of the structure, products are smooth in demolding and can not deform or crack when pulled, the percent of pass of the products is increased obviously by 20%, and production cost is lowered obviously.
Description
Technical field
The utility model relates to a kind of double-slider secondary core-pulling mechanism of tubular lamp casing die casting.
Background technology
Traditional like product generally adopts core-pulling mechanism of single sliding block, and endoporus package power is very large, is difficult to the demoulding.Product Die Casting difficulty, yielding, the drawing crack of product when the demoulding.Fraction defective is very high, causes production cost significantly to increase.
Utility model content
The utility model is in order to solve above-mentioned deficiency, and a kind of double-slider secondary core-pulling mechanism of tubular lamp casing die casting is provided.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of double-slider secondary core-pulling mechanism of tubular lamp casing die casting, it is characterized in that: comprise inner slide, outer slide, curved pin, cover half, oil cylinder, take-up housing and dynamic model, described inner slide is product endoporus core, coordinate with outer slide endoporus, can move backward; Described outer slide is product shape end face core, is fixed on take-up housing; Described curved pin is fixed on cover half, can stir inner slide; Described cover half is stationary mould for mould part, the agent structure of mould; Described oil cylinder is fixed on dynamic model side, drives take-up housing to move forward and backward when work; Described take-up housing and oil cylinder connect, and in the chute of dynamic model, move.
The utility model advantage is compared with prior art: adopt structure of the present utility model, the demoulding of product is smooth and easy, can not produce distortion and drawing crack phenomenon, and product percent of pass obviously improves 20%, and production cost obviously reduces.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the profile at A-A place in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of double-slider secondary core-pulling mechanism of tubular lamp casing die casting, it is characterized in that: comprise inner slide 1, outer slide 2, curved pin 3, cover half 4, oil cylinder 5, take-up housing 6 and dynamic model 7, described inner slide 1 is product endoporus core, coordinate with outer slide 2 endoporus, can move backward; Described outer slide 2 is product shape end face cores, is fixed on take-up housing 6; Described curved pin 3 is fixed on cover half, can stir inner slide 1; Described cover half 4 is stationary mould for mould parts, the agent structure of mould; Described oil cylinder 5 is fixed on dynamic model 7 sides, drives take-up housing 6 to move forward and backward when work; Described take-up housing 6 and oil cylinder 5 connect, and in the chute of dynamic model 7, move.
Mould is die sinking after injection completes, along with the movement of the dynamic model 7 of mould, curved pin 3 is stirred inner slide 1, and endoporus is loosed core and extracted out thereupon, the side of product is blocked by outer slide 2, can run-off the straight and play, when dynamic model 7 die sinkings put in place, oil cylinder 5 moves, drive take-up housing 6 and outer slide 2 to slide backward, product side departs from outer slide 2, and product can eject smoothly, and blank die casting completes.
Finally it should be noted that: above-described embodiment is only for the utility model example is clearly described; and the not restriction to embodiment; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here without also giving exhaustive to all embodiments; and apparent variation or the variation of being amplified out thus, still among protection domain of the present utility model.
