Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to an ejection structure of a pattern insert for an injection mold of a turn signal decoration frame. Background Art

[0002] The turn signal decoration frame is a decorative part installed at the turn signal of an automobile. It is mainly made of plastic materials and is injection-molded through an injection mold. In the injection process of the existing turn signal decoration frame mold, after injection is completed, it needs to be ejected and demolded through an ejection structure. Generally, an ejection structure needs to be set between the mold interior and the molding location, which requires a large space inside the mold. Moreover, after multiple ejections, the position opposite to the ejection structure is prone to deformation. Once deformed, the entire template needs to be replaced, resulting in high maintenance costs. Therefore, there is an urgent need to design an ejection structure of a pattern insert for an injection mold of a turn signal decoration frame that can overcome the above defects.

[0003] In order to overcome the deficiencies of the prior art, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a printing wastewater recycling system [Application No.: 201922020036.7], which includes a box body. The back of the box body is rotatably connected to a rotating plate through a rotating shaft. One side of the upper surface of the rotating plate is fixedly connected to a support plate. The support plate is arc-shaped. One end of the support plate passes through the box body and is fixedly connected to an installation rod. The outer wall of the installation rod is fixedly sleeved with a rubber sleeve. The outer wall of the rubber sleeve is fixedly embedded with bristles all over. Springs are arranged on both the front and back of the support plate. The other end of the spring is fixedly connected to a hook. Two connecting rings are arranged on both sides above the spring. The utility model uses the setting method of the cooperation of the installation rod and the spring. Through the elastic restoring force of the spring, it is convenient to keep the bristles on the rubber sleeve always in contact with the printing roller, so that when the printing roller rotates, the bristles can sink into the grooves of the printing roller, facilitating the cleaning of the residual pigments in the recesses of the printing roller, and thus thoroughly cleaning the printing roller. However, in the process of treating wastewater, this solution still cannot effectively adsorb flocs in the wastewater quickly, and has the defects of general filtering effect and long standing time required.
