The mold structure design of Led Floodlight

Led Floodlight is a point light source that can illuminate evenly in all directions. The housing is the main part of the lamp body, which is made of aluminum alloy die-casting. The wall thickness of the casting is relatively uniform. The heat sinks on the back of the case are denser, narrower, and deeper. The width of the thin end of the heat sink is 1.05mm, the slope is 3° on one side, and the depth is 12mm. When designing the mold, full attention should be paid to the flow resistance of the metal fluid in the mold, especially the molding of the 13 fins on the upper part of the casting. During die casting, if the direction of metal flow is not properly selected, it is easy to cause quality defects such as cold insulation, poor welding strength, air pockets in the casting, and incomplete formation of the sheet. Combined with the actual production needs of the enterprise, the structural characteristics of Led Floodlight castings, and the machining accuracy conditions of mold forming parts, etc., the structure of one mold and one cavity are adopted. So what is the mold structure design of Led Floodlight? Let's take a look at it next.

Selection and Design of Parting Surface

According to the Led Floodlight casting structure and parting surface design requirements, the end face of the shell mouth is selected as the parting surface of the dynamic and static molds. Considering the placement direction of the casting, the finished product should be kept on the movable mold side as much as possible. Due to the densely arranged heat sinks at the bottom of the casting, a brief theoretical analysis of the wrapping force generated by the Led Floodlight on the core is required.

Design of pouring system and overflow system

According to the design principles of the Led Floodlight die casting system, the metal flow should be filled in the direction of the heat sink to avoid flow marks, cold insulation, and incomplete filling of the shape of the heat sink. The diverter cone of the sprue in the sprue sleeve of Led Floodlight is designed in the form of a circular arc guide material, to speed up the filling speed of the material flow during die casting. The runner is designed with a guide structure that is consistent with the arc of the casting. Seven overflow air pockets are arranged on three sides of the casting forming cavity.

Mold structure and final assembly design

The working parts of the main molding part of the Led Floodlight mold are made of inserts, which are inserted into the movable and fixed molds respectively, to facilitate the work of the mold and the adjustment of the size of the molding part, as well as the repair, replacement, and adjustment of the vulnerable parts. Forming two 6mm round holes with the structural design of inserts. Due to the high temperature of the aluminum alloy of Led Floodlight die casting, its melting temperature is above 650, the heat treatment hardness of the sprue sleeve 15 should be slightly higher. To make the castings smoothly, under the premise that the heat sink does not affect the use, a push-out point is set, and a push-rod push-out is also set on the runner and the overflow bag respectively. The guiding accuracy between the movable and fixed molds is guaranteed by the fixed mold guide sleeve and the movable mold guide column.
