[0002] In-mold bimetallic one-piece forming is an advanced metal forming technology that achieves the versatility and integrity of parts by simultaneously forming two different metal parts in the same mold. This technology is widely used in the fields of automobiles, electronic equipment, etc., providing products with higher performance and durability.

[0003] However, although the in-mold bimetallic integrated molding technology has made significant progress in the manufacturing industry, the existing in-mold bimetallic integrated molding machines still have some shortcomings in the design and operation of the lower hopper. The specific problems are as follows:

[0004] Low material feeding accuracy: The feeding hopper of some existing in-mold bimetallic integrated forming machines has certain accuracy problems in quantitative feeding, which makes it difficult to meet the production requirements of high-precision workpieces. This may lead to waste and unstable quality in the production process.

[0005] Poor patency: The hopper design of some equipment is not sufficient to ensure the continuous patency of materials during the discharge process. The occurrence of blockage will affect production efficiency and may even cause equipment shutdown and maintenance.
