The upper die of the mold is installed on the upper pressing plate of the die combining machine, and the lower die is installed on the lower pressing plate of the die combining machine. The lower pressing plate is stationary, and the upper pressing plate moves downward under the drive of the driving device, driving the upper die to move downward and combine with the lower die. When producing, multiple die combining machines are arranged side by side, two transverse sliding rails are arranged at the rear side of each die combining machine, and an injection molding machine is slidably arranged on the transverse sliding rails. The injection molding machine moves to the corresponding die combining machine through the transverse sliding rails and injects material into the inner cavity of the combined mold.

[0003] In order to avoid the adhesion of the injection molded product to the inner cavity of the mold and facilitate demolding, the worker needs to spray the mold release agent into the mold in front of the die combining machine when the upper die and lower die are separated before injection. However, it is difficult to accurately control the spraying range when spraying the mold release agent, and part of the atomized mold release agent will pass through the die combining machine and come into contact with the rear injection head and the transverse sliding rail of the injection molding machine. Some chemicals in the mold release agent can corrode the injection head and the transverse sliding rail, resulting in a shortened service life of the part. CONTENT OF THE UTILITY MODEL

[0014] 1. The curtain is light in weight, and when the upper pressing plate of the mold closing machine moves up and down, the curtain can be moved by the pull rope. Due to the effect of the rotating part, when the upper pressing plate drives the upper mold to move downward, the curtain is pulled upward, and the curtain is not blocked when the injection head of the mold closing machine injects material into the mold after the upper mold and the lower mold are closed. When the upper pressing plate drives the upper mold to move upward, the curtain is lowered and blocked between the lower mold and the rear injection head, and at this time, the worker sprays the demolding agent on the upper mold and the lower mold, and the atomized demolding agent is blocked by the curtain, so that the demolding agent does not contact the injection head and the horizontal slide rail of the injection molding machine, thereby reducing the probability of corrosion of the demolding agent on these parts. Even if the curtain is corroded, compared with the metal or glass curtain, the replacement cost of the curtain is lower.

[0015] 2. The bottom of the curtain is connected with a counterweight plate, and the counterweight plate is slidably connected with the guide rod, so as to reduce the shaking of the curtain and ensure the blocking effect of the demolding agent.

[0016] 3. The curtain fixing frame is connected with the base of the mold closing machine through the mounting part, and the lower end of the guide rod is connected with the base of the mold closing machine through the mounting frame, so as to reduce the shaking of the guide rod and further reduce the shaking of the curtain, thereby ensuring the blocking effect of the demolding agent.

[0017] 4. The pull rope passes through the through holes of the curtain sheet parts of the curtain, and the pull rope can be used to reduce the shaking of the curtain.
