Description

Technical Field

[0001] The utility model relates to the technical field of plastic molds, in particular to a plastic mold for producing plastic rings. Background Art

[0002] Plastic ring, also known as plastic ring, is a product widely used in various fields. It is usually made of plastic and has good elasticity and durability, so it is used as a substitute for traditional metal or rubber products in many cases.

[0003] Announcement No. CN 215095106 U discloses a plastic mold for producing plastic rings. The plastic mold has a reasonable structural design. A hydraulic cylinder is used to drive a pressing plate to move downward, thereby squeezing the raw materials in the mold, so that the density of the produced plastic rings is relatively high, thereby ensuring the quality of the plastic rings. Secondly, a push plate is used to push the formed plastic rings out of the mold, which is convenient for the staff to take out and greatly improves the work efficiency.

[0004] The plastic mold for producing the plastic ring utilizes the contraction of the telescopic end of the hydraulic cylinder to move the two control rods upward, and drive the horizontal plate and the push rod to move upward, so that the push plate can push the molded plastic ring out of the mold to facilitate the staff to take it out. However, when the device drives the horizontal plate upward through the control rod, it can drive the push plate upward through the push rod. When the control rod does not move downward, the push plate cannot be retracted into the mold, so that the heated plastic material cannot be put into the mold. Therefore, improvement is needed.
