Abstract

The utility model discloses a prevent waste material spring mould structure, including going into son and drift, open porosely in going into sub - main part, install the plunger in the hole, the plunger front end is located young pore wall department, the plunger has elasticity, and its front end has a ball of a scalable removal, the ball do not receive under the external force state some in the protrusion outside the pore wall of going into the son. The utility model discloses an install a plunger additional in the main part of going into the son to set up the ball of scalable removal in plunger department, after the ball was crossed to the waste material, the ball can pop out and block the waste material, thereby reached and prevent waste material spring effect, and its structure is very simple, and accommodation is wide, and the effect is fine.

Description

A kind of anti-waste material bounce mold lamps structure

Technical field

This utility model relates to mould structure technical field, is specifically related to a kind of mould structure for part punching processing.

Background technology

Automobile die has punching technology, often occurs mould jump-scrap problem in punch process, causes weighing wounded product, mold damage, and needs cleaning mould, causes that production efficiency reduces. Along with the fast development of auto industry, auto parts and components die table sex chromosome mosaicism becomes increasingly conspicuous, it is necessary to ensures mould production stability, and improves production efficiency. In order to solve the problem of punched scrap rebound, thimble is generally installed additional on drift in existing punching processing mechanism, uses thimble to push down waste material, it is prevented that to come in contact between waste material and part product. But adding thimble there are disadvantages that, the membership that adds such as thimble reduces the structural strength of red needle, and when being empty in the middle of slug hole, thimble cannot play effect of bearing down on one accordingly; It addition, when punching is directly less, thimble cannot be installed.

Utility model content

The technical problems to be solved in the utility model is to provide that a kind of simple in construction, bounce-proof performance be good, the anti-waste material bounce mold lamps structure of wide adaptability.

For solving above-mentioned technical problem, this utility model adopts the following technical scheme that a kind of anti-waste material bounce mold lamps structure, includes into son and drift, it is characterised in that: in entering sub-main body, have hole, being provided with plunger in hole, plunger front end is positioned at the hole wall place into son; Plunger has elastic force, and its front end has the ball of a Telescopic movable, ball not by under external force state some outside the hole wall protruding from son.

Further, described ball adopts metal to make, as, it is possible to adopt the various common metal such as ferrum, copper, aluminum or rustless steel.

Drift moves downward, and the ball on depresses plunger is retracted into sub-main body, and drift continues to move downward, in-position; Drift moves upward, and separates with waste material, and the ball in plunger ejects, and blocks waste material so that it is cannot move upward, thus reaching anti-waste material pop effect.

This utility model by installing a plunger additional in the main body entering son, and arrange the ball of Telescopic movable at plunger place, after waste material crosses ball, ball can eject and block waste material, thus reaching anti-waste material pop effect, its structure is very simple, wide accommodation, and effect is fine.

In figure, 1 for entering son, and 2 is drift, and 3 is waste material, and 4 is plunger, and 5 is ball.

Detailed description of the invention

In the present embodiment, with reference to Fig. 1, described anti-waste material bounce mold lamps structure, including into son 1 and drift 2, have hole, be provided with plunger 4 in hole in entering sub 1 main body, plunger 4 front end is positioned at the hole wall place into son 1; Plunger 4 has elastic force, and its front end has the ball 5 of a Telescopic movable, ball 5 not by under external force state some outside the hole wall protruding from son 1.

Ball 5 adopts metal to make, as, it is possible to adopt the various common metal such as ferrum, copper, aluminum or rustless steel.

Moving downward with reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4 drift, the ball 5 on depresses plunger 4 is retracted into sub 1 main body, and drift 2 continues to move downward, in-position; Drift 2 moves upward, and separates with waste material 3, and the ball 5 in plunger 4 ejects, and blocks waste material 3 so that it is cannot move upward, thus reaching anti-waste material 3 pop effect.

Below this utility model is described in detail, the above, be only the preferred embodiment of this utility model, when not limiting this utility model practical range, namely all done impartial change according to the application scope and modified, all should still be belonged in this utility model covering scope.

Claims
