Description

A kind of antifriction alloy drawing die

Technical field

The utility model relates to a kind of drawing die, in particular to a kind of antifriction alloy drawing die.

Background technique

Mold is the important tool fixture of modern advanced manufacture, is largely used to machine-building, electronics, automobile, daily necessity Equal fields.

The drawing die of the prior art generallys use chromium steel material overall processing and is formed, by the huge friction for the type that is drawn into Under power effect, it is be easy to cause abrasion, so that the service life of mold is shorter, and demoulding need to could work as by external force from forming cavity In split away off, increase Operating Complexity, reduce production efficiency.For this purpose, it is proposed that a kind of antifriction alloy drawing die.

Utility model content

The main purpose of the utility model is to provide a kind of antifriction alloy drawing dies, can then formed by upper mold Slot pulls out pressing pin in the state of separating, extract this avoid pressing pin from forming tank inner cavity and rub with what internal chamber wall generated Power is wiped, friction is avoided to reduce the service life of mold, being provided separately of No.1 forming blocks and No. two forming blocks is improved can mold The separating of service life, No.1 forming blocks and No. two forming blocks just make forming tank inner cavity be divided into two make formed article automatically from It is split away off in forming tank, facilitates demoulding, be simple and efficient stripping operation, improve production efficiency, can effectively solve The problems in background technique.

To achieve the above object, the technical solution that the utility model is taken are as follows:

A kind of antifriction alloy drawing die, including upper die and lower die, the upper mold bottom is movably installed with lower die, under described Mould side is equipped with No.1 forming blocks, and No.1 forming blocks side slidably connects No. two forming blocks, and lower die by No.1 at Type block and No. two forming blocks compositions, the No.1 forming blocks and No. two forming blocks sides are fixed with limited block, the limit Run through on the inside of block and be equipped with threaded rod, and threaded rod one end is actively plugged in No.1 forming blocks and No. two forming blocks sides, institute respectively It states the threaded rod other end and is plugged with motor.

Further, the No.1 forming blocks and No. two forming blocks are flexibly connected by connecting rod, are opened on the inside of the lower die Equipped with No.1 sliding slot, and connecting rod is located at No.1 sliding slot inner cavity.

Further, the upper die and lower die are connected by guide rod, offer No. two sliding slots on the inside of the upper mold both ends, Sliding tenon is welded at the top of the guide rod, and sliding tenon is slideably positioned in No. two sliding slot inner cavities.

Further, the upper mold bottom surface is welded with pressing pin, and the lower die top surface offers forming tank, and Pins position is pressed at the top of forming tank.

Compared with prior art, the utility model has the following beneficial effects:

1. lower die is made of semicircular No.1 forming blocks and No. two forming blocks, No.1 forming blocks and No. two forming blocks are just It is separated in half from the center of lower die, is separated in half forming tank positioned at No.1 forming blocks and No. two forming blocks sides, one The side of number forming blocks and No. two forming blocks is fixed with limited block, and limited block is fixedly mounted on station, and in limited block Side, which is run through, is equipped with threaded rod, and one end activity of screw rod is plugged on the side of No.1 forming blocks and No. two forming blocks, and another End is plugged with motor, so when motor rotation rotates threaded rod on limited block while marching forward, so that No.1 be formed Block and No. two forming blocks push merging at one piece in opposite directions, and then lower die pushing merges with lower die is molded over object in forming tank Then motor reversal is made threaded rod drive No.1 forming blocks and No. two forming blocks to pusher, to make guide rod with cunning by chamber No. two sliding slot inner cavities to a Slideslip, the separating of No.1 forming blocks and No. two forming blocks just divides forming tank inner cavity one to be tenon Two split away off formed article in forming tank automatically, facilitate demoulding, are simple and efficient stripping operation, improve production Efficiency.

2. then upper mold then can forming tank separate in the state of make pressing pin pull out, this avoid pressing pin from The frictional force generated with internal chamber wall is extracted in forming tank inner cavity, and friction is avoided to reduce the service life of mold, No.1 forming blocks and two Being provided separately of number forming blocks improve can mold service life.
