Description

Technical Field

[0001] The present application relates to the technical field of die, and in particular to a die for an injection molding machine. Background Art

[0002] The die is a molding mold that can be used for injection molding machines after the blank has been normalized. After the die is installed on the injection molding machine, the injection molding machine heats, melts, and plasticizes the plastic particles, squeezes them into the molding mold, and then fixes the plasticized parts into shape through the die.

[0003] The existing Chinese patent with announcement number CN219153585U discloses an injection molding die, including: a machine platform, a frame is installed on the outer side of the upper end of the machine platform, and a water tank is arranged at the lower end of the machine platform, a discharge pipe is installed at the right end of the water tank, and a die body is arranged on the inner side of the upper end of the machine platform; an air pump is arranged at the lower end of the frame, a push rod is installed at the lower side of the air pump, and a mounting plate is installed at the connection between the pressure block and the die body; a rotating rod, a single body of which is respectively installed on the left and right sides of the machine platform, an adjustment rod is arranged at the connection between the rotating rod and the machine platform, a movable rod is arranged on the upper side of the adjustment block, a fixed block is arranged at the connection between the positioning frame and the die body, and a cold zone assembly is installed on both sides of the front and back of the machine platform. The injection molding die is relatively simple to install between the die and the machine platform, which is conducive to disassembling and replacing the die from the machine platform, and has a good cooling effect, avoiding the die from being damaged by high temperature for a long time.

[0004] However, the above-mentioned existence has the disadvantage of the molding die: the device engages the die by setting an adjusting rod and a rotating rod to complete the rapid installation and disassembly of the die, but the device cannot quickly demold the material after the material is injection molded, so that the material stays in the die for too long, which increases the injection molding cycle, reduces production efficiency, and also reduces the utilization rate and service life of the equipment. The device uses a movable rod to drive the positioning frame to move so as to install and disassemble the die, but this installation and disassembly method is not stable.

[0005] Therefore, we propose an injection molding die to solve this problem.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
