Description

Technical Field

[0001] The utility model relates to the technical field of mold demoulding, in particular to a device that is convenient for rotary demoulding. Background Art

[0002] With the continuous development of new materials, some physical properties of many new materials are close to or even higher than those of metals. At the same time, they are far higher than metals in terms of acid and alkali resistance and corrosion resistance. Among the aforementioned new materials, common plastics are widely used in some aspects due to their advantages such as strong plasticity, strong chemical corrosion resistance, and good insulation. At present, for plastic products with more complex shapes, injection molding and subsequent ejection and demolding are mostly used to prepare them. However, some molded plastic parts have a helical tooth structure on the outside, and the extension direction of the convex part is inconsistent with the ejection direction of the plastic part during the demolding process, so that the molded plastic part needs to provide additional rotational force during the demolding process to rotate the molded plastic part during the ejection process, thereby completing the rotational demolding of the plastic part.

[0003] Most of the common demoulding methods currently used are to force the product out of the mold cavity. Such a strong demoulding method will damage the helical tooth structure of the product during the process of the product leaving the mold. Therefore, it is urgent to design a device that is convenient for rotary demoulding to solve the above problem. Utility Model Content
