Description

A Quick-Removable Mold Insert

technical field

The utility model relates to a mold insert, in particular to a quickly detachable mold insert.

Background technique

Various inserts are used in the mold for its assembly, reinforcement, and connection. When the mold is maintained, the inserts need to be taken out. The traditional inserts are extremely inconvenient to take out due to the lack of a force point, and it is very easy to scratch the outer surface of the inserts when pulled out after being clamped by other clamps. In order to solve the above problems, a screw hole is generally processed on the outer surface of the solid insert, and then screwed into the screw hole through the screw rod, and the insert is pulled out by pulling the screw. Hollow inserts cannot use the above method due to the lack of screw hole punching positions, and can only be clamped and pulled by traditional clamps.

Utility model content

The purpose of the utility model is to provide a mold insert that can be quickly removed without clamps.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a quick detachable mold insert, its body is square, and a through square hole is opened from top to bottom at the central position; the outer surface of the body is There are at least two notches with a depth of 3 mm at four right-angle positions 5 mm from the upper end surface of the body; the opening size of the notch increases linearly from the opening to the inside, and the bottom surface of the notch is arc-shaped; the opening edge of the notch is rounded and chamfered.

When the utility model is implemented, insert the front end of a pointed rod into the gap, rely on the pointed rod matched with the fulcrum, lift the mold insert, and make it withdraw from the hole.

The utility model has a simple structure and a reasonable design, and solves the problem of quick removal of the mold insert with holes.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a schematic diagram of the structure of the utility model when it is used with a pointed rod with a fulcrum.

Detailed ways

For the convenience of further understanding of the utility model, an embodiment is given in conjunction with the accompanying drawings to further illustrate the utility model.

Example:

As shown in Figures 1 and 2, the utility model is a mold insert that can be quickly removed. There are at least two notches 2 with a depth of 3 mm on four right-angle positions of 5 mm on the upper end surface; Arc shape; the opening edge of the notch 2 is rounded and chamfered.
