Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a spliced ​​injection mold. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, and the ability to form parts with complex shapes.

[0003] A Chinese patent discloses a spliced ​​injection mold, with the publication number CN213766973U, comprising a bottom plate, a base fixedly mounted on the top of the bottom plate, a lower mold being arranged on the top of the base, a bracket fixedly mounted on the top of the bottom plate and outside the base, a cylinder fixedly mounted on the bottom of the inner cavity of the bracket, and an upper mold fixedly mounted on the telescopic end of the cylinder; the utility model is provided with gears and gear rings, and when a user uses the device, the molten plastic material is injected into the mold cavity provided on the top of the lower mold, and then the cylinder is opened through an external controller, and the telescopic end of the cylinder drives the upper mold to move downward, and when the upper mold extrudes the lower mold, the excess plastic will be squeezed into the inner cavity of the shell, at which time the output shaft of the motor drives the gear to rotate, the rotation of the gear drives the gear ring to rotate, and the rotation of the gear ring drives the scraper rod to rotate in the inner cavity of the shell through the cover plate, so that the plastic material inside the shell is discharged to the outside through the discharge port.

[0004] However, it still has the following disadvantages: the device controls the extension of the cylinder to make the upper mold move downward to close the lower mold. However, in order to ensure product quality, the upper and lower molds must be tightly connected. After using the cylinder to close the mold multiple times, due to the structural displacement caused by vibration, it is difficult to ensure that the upper and lower molds are tightly connected, affecting product quality. To this end, we proposed a spliced ​​injection mold to solve this problem. Utility Model Content
