The utility model discloses a die-casting mold for a lamp shell cover, which comprises a fixed mold seat plate, a fixed mold plate, a moving mold plate and a moving mold support plate arranged sequentially from top to bottom; a fixed mold insert is arranged at the lower part of the fixed mold plate, a moving mold insert is arranged at the upper part of the moving mold plate, and four square patterns are formed between the fixed mold insert and the moving mold insert. At the same time, the die casting mold of the lamp shell cover also includes a center unfolding mold runner system, which comprises a direct runner running through the fixed mold seat plate and the fixed mold plate from top to bottom, a main and transverse runner located in the middle of the four casting mold cavities and connected with the straight runner, and a number of runners for connection. The main transverse runner and the secondary transverse runner adjacent to the mold cavity of the casting are provided, and the sectional area of the main transverse runner and the secondary transverse runner are gradually reduced along the pouring direction and are inclined downward at the same time; the advantages of the utility model are that the production efficiency is high, the transmission of static pressure is favorable, and the filling speed of the lamp shell cover is increased.
【技术实现步骤摘要】
一种灯体壳盖压铸成型模具
本技术涉及一种压铸成型模具,尤其是涉及一种灯体壳盖压铸成型模具。
技术介绍
灯体壳盖作为一种非精密压铸件,通常需大批量生产。但是现有技术中压铸成型模具一次只能压铸一件灯体壳盖,不仅生产效率低,而且产品质量也较差。
技术实现思路
本技术目的是:提供一种不但生产效率高,而且有利于静压力的传递,还可提高对灯体壳盖充填速度的灯体壳盖压铸成型模具。本技术的技术方案是:一种灯体壳盖压铸成型模具,包括自上而下依次设置的定模座板、定模板、动模板、动模支撑板;在所述定模板下部设有定模镶件,在所述动模板上部设有动模镶件,在所述定模镶件和所述动模镶件之间形成四个呈正方形排布的铸件成型腔;同时该灯体壳盖压铸成型模具还包括中心展开型浇道系统,所述中心展开型浇道系统包括自上而下贯穿定模座板和定模板的直浇道,设置在四个铸件成型腔中部并与直浇道相连通的主横浇道,以及若干个用于连通所述主横浇道和相邻铸件成型腔的副横浇道;且所述主横浇道和所述副横浇道的截面积沿浇注方向逐渐减小同时向下倾斜设置,金属液通过主横浇道和副横浇道向两侧分布的铸件成型腔浇注,不但有利于静压力的传递,而且还可提高对灯体壳盖的充填速度。作为优选的技术方案,还包括顶出机构,所述顶出机构包括置于动模支撑板下部、且左右对称的两垫块,在两垫块之间自下而上设有推板、推杆固定板、以及若干个推杆,所述推杆顶部依次穿过动模支撑板、动模板、动模镶件到达铸件成型腔的推出点,压铸完成后顶出机构顶出灯体壳盖铸件,既简化了模具结构又能顺利脱模,并有效防止灯体壳盖铸件断裂。作为优选的技术方案,在所述动模支撑板下部固定有一竖直向下 ...
