Abstract

The invention relates to a forging and moulding die for a composite insulator ball socket fitting. The forging and moulding die is characterized by comprising an upper die plate, a convex die, movable die holders, a fixed die holder, a lower die holder and a demoulding mandril, wherein the convex die is arranged on the upper die plate; a left die core and a right die core are respectively arranged on the left movable die holder and the right movable die holder, and the left die core and the right die core are assembled to form a cavity for accommodating the ball socket fitting; the fixed die holder is fixed on the lower die plate, an inner cavity is formed in the center of the fixed die holder, the left movable die holder and the right movable die holder are arranged in the inner cavity of the fixed die holder, and the left movable die holder and the right movable die holder are matched with the side wall of the inner cavity of the fixed die holder through a guide structure, wherein the upper end of the guide structure inclines outwards. In the compression process, a ball socket fitting blank is subjected to pre-forging and trimming and then put in the die cores, the convex die moves downwards, and a ball socket is subjected to once compression moulding in the die cores; in the demoulding process, a demoulding cylinder jacks upwards, the die cores move upwards along with the left movable die holder and the right movable die holder, so that the demoulding is realized; and the forging and moulding die is high in compression efficiency, and the manufactured ball socket fitting is low in rejection rate.

Description

A kind of composite insulator ball-and-socket gold utensil forging molding mould

Technical field

The present invention relates to a kind of forging molding mould, particularly a kind of composite insulator ball-and-socket gold utensil forging molding mould.

Background technology

Composite insulator ball-and-socket gold utensil as shown in Figure 1, it has a ball-and-socket b at hardware end a, present composite insulator ball-and-socket gold utensil all adopts the method for casting during fabrication, its existent defect is: interior tissue is loose, shrinkage cavity, defects i.e.cracks are arranged, can't meet the quality requirement, have larger potential safety hazard, and scrap more.

Summary of the invention

The technical problem to be solved in the present invention provides the composite insulator ball-and-socket gold utensil forging molding mould that a kind of percent defective is low, working (machining) efficiency is high.

For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of composite insulator ball-and-socket gold utensil forging molding mould, its innovative point is: comprise cope match-plate pattern, punch, active mould seat, fixedly die holder, lower bolster and demoulding push rod, punch is installed on the cope match-plate pattern; Left core rod and right core rod are installed respectively on left active mould seat, the right active mould seat, are consisted of the die cavity of placing the ball-and-socket gold utensil behind the left and right core rod matched moulds; Fixedly die holder is fixed on the lower bolster, and fixedly the die holder center has an inner chamber, and left and right active mould seat places the fixedly inner chamber of die holder, and left active mould seat and right active mould seat are tilted to the guide frame in the outside by the upper end and cooperate with fixing die holder intracavity sidewall; Guide frame is specially: have T-slot at the fixing sidewall of die holder inner chamber, T-slot is obliquely installed, and tilt the laterally outside of left and right active mould seat, the upper end of T-slot all arranges the T-shaped slide block of active mould seat that embeds T-slot; Demolding structure is specially: the lower end of left and right active mould seat has the T shape groove of horizontal direction, and the upper end of demoulding push rod has demoulding push rod T shape slide block, and demoulding push rod T shape slide block embeds in the T shape groove of left and right active mould seat simultaneously.

Further, the angle of the inclined plane of described T-slot and vertical direction is between 15-20 °.

The invention has the advantages that: during compacting, ball-and-socket gold utensil blank through blocking, cutting edge is placed in the core rod, punch is descending, with core rod in ball-and-socket is once compressing; During the demoulding, the stripping tank jack-up that makes progress is moved and is opened to both sides on the core rod following left sliding seat, can realize the demoulding, and compacting efficient is high, and the ball-and-socket gold utensil percent defective that makes is low.

Description of drawings

Fig. 1 is composite insulator ball-and-socket gold utensil profile.

Fig. 2 is composite insulator ball-and-socket gold utensil forging molding mould structure schematic diagram of the present invention.

Fig. 3 is fixedly die holder and active mould seat top view among the present invention.

The specific embodiment

Shown in Fig. 2,3, comprise cope match-plate pattern 8, punch 9, left active mould seat 1, right active mould seat 2, left core rod 3 and right core rod 4, fixedly die holder 5, lower bolster 6, demoulding push rod 7.

Punch 9 is installed on the cope match-plate pattern 8, and punch 9 is that ladder is cylindric, and its lower end is the globular model of rounding off.

Active mould seat comprises left active mould seat 1 and right active mould seat 2, and left core rod 3 and right core rod 4 are installed respectively on left active mould seat 1, the right active mould seat 2, cooperates the die cavity that consists of the ball-and-socket gold utensil behind left core rod 3, right core rod 4 and punch 9 matched moulds.

Fixedly die holder 5 is fixed on the lower bolster 6, fixedly die holder 5 centers have an inner chamber, left active mould seat 1, right active mould seat 2 place the fixedly inner chamber of die holder 5, and left active mould seat 1 and right active mould seat 2 are tilted to the guide frame in the outside by the upper end and cooperate with fixing die holder 5 intracavity sidewalls.

This guide frame has T-slot at the fixing sidewall of die holder 5 inner chambers as shown in Figure 2, and T-slot is obliquely installed, and its upper end tilts laterally, and the angle of inclined plane and vertical direction is about 15-20 °; The outside of left active mould seat 1, right active mould seat 2 all arranges the T-shaped slide block of active mould seat that embeds T-slot.

During the demoulding, adopt single demoulding push rod structure, the lower end of left active mould seat 1, right active mould seat 2 has the T shape groove of horizontal direction, and the upper end of demoulding push rod 7 has demoulding push rod T shape slide block, and demoulding push rod T shape slide block embeds in the T shape groove of left active mould seat 1, right active mould seat 2 simultaneously.In addition, according to those skilled in the art's general knowledge, at fixing die holder 5 guide frame, limited block etc. are set.

Operation principle:

During the punching press ball-and-socket, left core rod 3 and right core rod 4 are opened slightly, and the composite insulator ball-and-socket gold utensil of process blocking places in left core rod 3 and the right core rod 4, and cope match-plate pattern 8 is descending, stamps out the ball-and-socket of ball-and-socket gold utensil by punch 9; During the demoulding, cope match-plate pattern 8 is up, and punch 9 leaves core rod, and demoulding push rod 7 ejects, and core rod can be realized the demoulding with moving and open to both sides on left sliding seat 1, the right sliding seat 2, and compacting efficient is high, and the ball-and-socket gold utensil percent defective that makes is low.
