Description

Technical Field

[0001] The utility model relates to the technical field of plastic molds, in particular to an ejection structure of a plastic mold. Background Art

[0002] Chemical plastic barrels, also called plastic chemical barrels, are developed and blow-molded using scientific formulas. They have various colors and beautiful appearance. They meet packaging indicators in terms of acid and alkali resistance, corrosion resistance, leakage resistance, no fading, and no deformation. They are the ideal choice for long-distance transportation of chemical product packaging materials. Blow molding is currently widely used to produce chemical plastic barrels.

[0003] Due to the large volume of chemical plastic barrels, the contact area between the blow molded parts and the existing molds is large, and the adhesion between the blow molded parts and the molds is also large, which causes inconvenience in demoulding. In addition, the blow molds in the existing technology generally adopt the left-right splicing method. When the left mold and the right mold are separated, the blow molded parts will be stuck on the left mold or the right mold, causing damage to the blow molded parts. The existing blow molds are driven by multiple power sources, resulting in increased processing costs and difficult to disassemble during maintenance. To this end, we provide a plastic mold ejection structure to solve the above problems. Utility Model Content
