Description

Technical Field

[0001] The utility model relates to the technology of mold field, in particular to a mold with a two-way ejection structure. Background Art

[0002] At present, molds are various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc., and injection molds are the most important in the injection molding process; injection molding is also called injection molding, which is an injection and molding molding method. During the injection molding process, the workpiece is formed by injecting the material into the inside of the mold. The processing speed is fast and the work efficiency is high. Traditional molded workpieces are generally removed from the mold manually. Due to the high temperature of the molded workpiece after injection molding, it is inconvenient for users to remove the workpiece.

[0003] Later, an injection mold that can eject workpieces appeared on the market. An ejection mechanism was added to the movable mold to eject the workpiece after injection molding, so that the user can take the workpiece out of the mold. However, the existing workpiece ejection mold structure is poorly designed, and its ejection mechanism is only provided on the movable mold. When the workpiece after injection molding is bonded to the fixed mold, the user needs to manually remove the workpiece. In addition, during the removal process, the workpiece is easily scratched or torn, making the workpiece unusable. It has good usability but a small scope of application.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0008] As a preferred solution, a plurality of push rods are provided, and the push rods are arranged in a spaced manner around the edge of the core.

[0009] As a preferred solution, there are at least two second ejection mechanisms, and the two second ejection mechanisms are arranged at intervals along the length direction of the fixed mold and are located in the middle of the cavity.

[0010] As a preferred solution, a connecting plate is provided between the push block and the elastic return member, the connecting plate is provided inside the fixed mold, the push block is provided with a plurality of elastic return members which are arranged on the connecting plate at intervals along the length direction of the fixed mold, and a plurality of elastic return members are provided with a plurality of elastic return members which are arranged in a spaced manner inside the fixed mold, one end of the plurality of elastic return members is connected to the connecting plate, and the other end is connected to the fixed mold.
