Abstract

The utility model discloses a stamping insert, a main body of which is a hollow cylinder body; the inner wall of a cylinder is provided with screw threads; the lower end of the main body is provided with an edge extending to the outer side; four rectangular stamping grooves are positioned around the outer side of the edge; and the sides of the stamping grooves are stamped upwards, so that bulge check blocks can be formed. The stamping insert provided by the utility model can be better matched with a mould due to the improvement of structure, does not cause damage to the mould, and brings economic benefit to enterprises.

Description

A kind of punching press mold insert

Technical field:

The utility model relates to the machining equipment field, is a kind of punching press mold insert specifically.

Background technology:

Former diesel oil plastic fuel tank fuel outlet is generally used steel-casting; Its shortcoming: weight is big, and poor heat conductivity causes rotation molding, and plastics and steel-casting fuel outlet parcel is bad herein, its easy oil leakage, torque difference; Be the excessive risk point of product quality.

Summary of the invention:

For solving the problem that prior art exists, the spy provides a kind of punching press mold insert, by the improvement of structure, it can better be matched with mould, can not cause mould to damage.

The technical solution adopted in the utility model:

A kind of punching press mold insert is characterized in that: punching press mold insert main body is a hollow cylinder, and cylinder inner wall has screw thread, and there is the edge that stretches out laterally the main body lower end, and there are a plurality of jet-beddings at described edge around the outside, and the side of jet-bedding is risen to upper punch, forms protruding block.

Advantage of the present utility model:

The utility model is according to conduction of rotational moulding heat and the principle of heat distribution to quality influence, improve thermal conductivity herein on the one hand, be exactly that to change mold insert be stamping parts on the other hand, reduce the weight of mold insert, under equal heat conduction energy, temperature is higher, rotation molding is thicker herein, has solved the bad easy oil leakage problem of parcel, and moment improves greatly, help producing in enormous quantities
