Background technique

With the continuous advancement of technology, the design of metal minimalist style is more and more favored by consumers. At present, in the manufacturing process of the metal storage basket, the connection between the net and the frame is through the worker inserting the net port into the frame, and then putting the net and the frame into the pressing equipment to compress to make a Formed storage basket. As a result, the production efficiency of the storage basket is low, labor-intensive, and high production costs.

Therefore, it is necessary to research and develop a production process capable of automatically forming the storage basket, and a molding die for realizing the production process, so as to solve the above-mentioned technical problems.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide an automatic forming process and a forming mold for the storage basket, which are used to solve the problem that the existing storage basket production process adopts manual assembling of the frame and then puts it into the equipment for compression molding, which is labor-intensive, labor-intensive and low in production efficiency. , resulting in high production costs.

In order to achieve the above-mentioned purpose, the present utility provides a kind of automatic forming process of the storage basket, and the specific embodiments are as follows:

An automatic forming process for the storage basket, the automatic forming process for the storage basket adopts a forming mold, the forming mold includes a fixed mold and a movable mold, and the open end of the storage basket is bent with a skirt, including the following steps:

A1: Put the frame into the fixed mold, and the clamping block on the fixed mold clamps the frame;

A2: Put the opening of the storage basket into the fixed mold toward the frame, the forming mold is closed, and the fixed mold and the movable mold clamp the storage basket;

A3: The push block on the fixed mold pushes the inner side of the peripheral wall of the storage basket to keep the storage basket in a tensioned state and maintain the shape of the storage basket;

A4: The moving mold continues to press down until the basket is clamped by the fixed mold and the fixed mold, and after the skirt and frame of the opening of the storage basket are initially crimped, the moving mold stops pressing down, and then the push block resets;
