Description

Technical Field

[0001] The utility model relates to the technical field of injection molding of smoke sensor shells, in particular to a slider structure with slight product injection molding clamping line. Background Art

[0002] Smoke sensors, also known as smoke alarms, fire smoke alarms, smoke sensors, etc., are devices used to detect smoke concentrations. Smoke sensors achieve fire prevention by monitoring smoke concentrations. The overall appearance of smoke sensor shell products is required to be high, and no clamp line segment differences are allowed. The position clamp line refers to the intersection of the position slider in the mold and the plastic part during the injection molding process. This clamp line usually appears at the edge of the plastic part or in a specific area, which will affect the appearance and function of the product. The overall appearance of the smoke sensor product shell is required to be high, and no clamp line segment differences are allowed. At present, the existing position clamp lines cannot be controlled consistently, resulting in the smoke sensor shell product being prone to position clamp lines during injection molding, affecting the beauty of the product appearance. Therefore, we need to propose a slider structure with a slight injection clamp line. Utility Model Content
