Description

Mold insert tolerance-tolerant injection mold structure

Technical Field

The utility model belongs to the technical field of the machining technique and specifically relates to an allow injection mold structure of mold insert tolerance.

Background

Due to the technical requirements, some injection-molded products need to contain metal inserts to improve the assembly strength of the products. When a product containing the metal insert is injected, a certain surface of the insert can be contacted with a mold cavity, and the phenomenon of poor injection molding is easy to occur due to the error of the height of the insert. When the insert is poor in descending, the phenomenon of hole blocking due to material passing is easily caused, excess materials need to be manually removed, time and labor are wasted, and products are easily damaged; when the insert is poor, the mold is easy to be jacked, so that the mold is damaged.

SUMMERY OF THE UTILITY MODEL

In view of above-mentioned technical background, lead to moulding plastics bad problem, design for solving the mold insert tolerance the utility model relates to a permit injection mold structure of mold insert tolerance. The utility model provides an installation polyurethane plate structure on injection mold's installation mold insert's reference column for the length of extension reference column, when the mold insert has the error, the polyurethane plate plays certain face and the die cavity laminating cushioning effect of guaranteeing the mold insert.

The utility model discloses a realize through following technical scheme:

an injection mold structure allowing insert tolerance comprises a mold structure base, a positioning column and a polyurethane plate; the method is characterized in that: the die structure base comprises a die structure base A and a die structure base B, a positioning column is installed at the upper end of the die structure base A, a positioning pin is arranged at the lower end of the die structure base A, and a positioning hole A which corresponds to the positioning pin and can be inserted into the positioning pin is arranged at the upper end of the die structure base B; the polyurethane plate is provided with a through hole B which corresponds to the positioning pin and can be inserted with the positioning pin, and the polyurethane plate is assembled between the mold structure base A and the mold structure base B; and the positioning pin at the lower end of the mold structure base A is assembled on the positioning hole A of the mold structure base B after penetrating through the through hole B of the polyurethane plate.

As a further scheme of the utility model, the top of reference column is provided with the cylinder type structure of mountable metal mold insert, and the diameter of cylinder type structure is less than the diameter of reference column.

As a further aspect of the present invention, the overall dimensions of the polyurethane board are smaller than those of the mold structure base a and the mold structure base B.

As a further proposal of the utility model, the mold structure base, the positioning column and the polyurethane plate are all milled at the processing center.

By adopting the technical scheme, the beneficial effects of the utility model are that: the problem of poor injection molding caused by insert tolerance is solved, the production efficiency is improved, and waste products are reduced. And effectively protects the die. The utility model discloses the structure is reliable, easily realizes and promotes, and the processing cost is low.
