Abstract

The utility model relates to a die used for drill tail molding screws, and the die is composed of a die basal body and a drill tail molding part, and is characterized in that the drill tail molding part is arranged on a corner part of the die basal body; the drill tail molding part can be designed into a square, a rectangle or an anomalous polygon according to the practicability; the die basal body is welded together with the drill tail molding part. Materials of the drill tail molding part are cemented carbides; the material of the die basal body is tool steel, alloy tool steel, rapid tool steel, etc. Because the die uses the cheap tool steel, the alloy tool steel, the rapid tool steel, etc. on the part of the die basal body and uses the cemented carbides on the important drill tail molding part, the cost is saved and the drill tail molding part can reach the required hard strength, the service life is extended, and the cost is reduced.

Description

Bore tail shaped screw mould

Technical field

The utility model relates to a kind of mould that screw is used of producing, particularly a kind of brill tail shaped screw mould.

Background technology

Produce the mould that holding screw is used, select for use its material also different according to the difference of its matrix, as tool steel, alloy tool steel, high-speed tool steel and carbide alloy etc., but when the mould that uses single material making holding screw to use, the meeting appearance is not high because of material hardness, make the too early damage of mould, need more mold exchange, as use the material of the good carbide alloy of hardness, be to have prolonged service life, but the relative cost expense is too high, and user's financial burden is increased the weight of, and at this moment prolongs its life-span with regard to needing a kind of problem that can solve hardness, the way that expense is reduced relatively reduces the too high problem of cost.

Summary of the invention

At the deficiency that above-mentioned technical problem exists, the purpose of this utility model provides a kind of brill tail shaped screw mould.

The technical solution of the utility model is as follows:

A kind of brill tail shaped screw mould, comprise: die matrix, brill tail moulding position, mould locating slot, it is characterized in that: boring the bight of tail moulding position design at die matrix, bore tail moulding position and can be designed to square, rectangle or irregular polygon according to practicality, die matrix with bore tail moulding position and weld together.Bore the material carbide alloy at tail moulding position, the material of die matrix tool steel, alloy tool steel, high-speed tool steel etc.

It is cheap tool steel, alloy tool steel, high-speed tool steel etc. that the utility model has because of what use at the die matrix position, and use carbide alloy at important brill tail moulding position, can save cost like this, can make brill tail moulding position reach needed hard intensity again, prolong service life, reduced the problem of cost.

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is a plan structure schematic diagram of the present utility model;

Fig. 3 is a main TV structure schematic diagram of the present utility model;

Fig. 4 is a side-looking structural representation of the present utility model.

Among the figure: 1 die matrix, 2 bores tail moulding position, 3 mould locating slots.

The specific embodiment

As shown in the figure, boring the bight of tail moulding position 2 designs at die matrix 1, bore tail moulding position 2 and can be designed to square, rectangle or irregular polygon according to practicality, die matrix 1 welds together with brill tail moulding position 2, bore the material carbide alloy at tail moulding position 2, the material of die matrix 1 tool steel, alloy tool steel, high-speed tool steel etc.

It is cheap tool steel, alloy tool steel, high-speed tool steel etc. that the utility model has because of what use at die matrix 1 position, and use carbide alloy at important brill tail moulding position 2, can save cost like this, can make brill tail moulding position reach needed hard intensity again, prolong service life, reduced the problem of cost.
