Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold with an inverted molding structure. Background Art

[0002] In order to avoid leaving gate marks on the surface of the product and avoid affecting the appearance of the product, the injection mold will be designed as an inverted structure to set the glue inlet and ejector on the same side of the injection molded product to ensure the appearance quality of the product; after the inverted mold is injected, the movable mold and the fixed mold need to be separated, the injection molded part is ejected from the fixed mold, and then the movable mold is installed on the fixed mold for the next injection molding. Manual mold opening and ejection operations are inefficient, and workers cannot carry the mold if it is too heavy, resulting in low production efficiency of the inverted mold, which is not conducive to the automated production of the product and increases labor costs.

[0003] A Chinese patent discloses a flip mold (authorization announcement number CN212653782U). This patented technology sets a first oil cylinder connected to the movable mold fixed plate on the fixed mold base of the flip mold, and sets a second oil cylinder connected to the fixed mold base on the ejector panel of the flip mold. The first oil cylinder and the second oil cylinder drive the telescopic rod to realize the automatic mold opening, ejection and reset of the flip mold. At the same time, the relative position of the movable mold and the fixed mold is sensed by the distance sensor, and the movement of the flip mold group is automatically controlled by the main control board, which reduces the labor intensity of workers, facilitates the realization of automated production of flip molds, reduces the errors caused by manual operation, greatly improves production efficiency and product precision, and reduces labor costs.

[0004] However, it has certain disadvantages: when the mold is opened, the temperature of the injection molded product is often high. Although the product has been ejected upward, the staff still needs to manually remove it, which can easily cause burns. Moreover, for injection molding production lines that require continuous production, workers need to repeatedly perform the removal operation, which is labor-intensive and easily leads to worker fatigue, thereby affecting work efficiency and product quality.
