Lost foam casting mold for motor shell ejection device

Abstract

The invention discloses a lost foam casting mold for a motor shell ejection device. The lost foam casting mold comprises a lower mold body, an upper mold body and a controller, wherein a lower mold air chamber is formed in the upper end of the lower mold body, a positioning groove is formed in one side of the lower mold air chamber, a feeding pipe is arranged below the positioning groove, triangular support legs are arranged on one side of the feeding pipe, cooling holes are formed in the outer surface of the lower mold body, hinges are arranged at the lower end of the upper mold body, the lower mold body is fixedly connected with the hinges, and an upper mold air chamber is formed above the hinges. The lost foam casting mold for the motor shell ejection device is provided with an anti-scratch film, an induced draft fan and the controller, can prevent scratches on the surface of a display screen after long-term use and protect the definition of the display screen, also has good coolingperformance, can increase the forming speed of components, is more convenient to control, can effectively improve the working efficiency, is applicable to different work conditions and brings betteruse prospects.

Description

technical field [0001] The invention relates to the field of lost foam molds, in particular to a lost foam mold for a motor housing ejector. Background technique [0002] The key to the success of lost foam mold casting is to understand the importance of close cooperation between the casting manufacturer, the user and the mold designer. Model forming requirements, castings with grooves, inner cavities, connecting channels or other holes, need to use sand cores when using other casting methods, in the EPC process, you can use loose blocks or glue the block models together According to the shape of the casting, the parting surface is determined according to the shape of the casting. Generally, the parting surface of lost foam casting is similar to other casting processes, but it is slightly different in some details. The production designer should work with the mold designer. Determine the parting surface, the location of the glued surface and the desired characteristics, you...

[0002] The key to the success of lost foam mold casting is to understand the importance of close cooperation between the casting manufacturer, the user and the mold designer. Model forming requirements, castings with grooves, inner cavities, connecting channels or other holes, need to use sand cores when using other casting methods, in the EPC process, you can use loose blocks or glue the block models together According to the shape of the casting, the parting surface is determined according to the shape of the casting. Generally, the parting surface of lost foam casting is similar to other casting processes, but it is slightly different in some details. The production designer should work with the mold designer. Determine the parting surface, the location of the glued surface and the desired characteristics, you can reduce the number of model blocks. The original lost foam mold has poor stability when placed, and when a collision or tilt event occurs, it will be very large. The yield rate of parts is reduced to a certain extent. The heat dissipation effect of the original lost foam mold is poor, which reduces the forming speed of the parts. The control of the lost foam mold itself is more complicated and requires multiple people to operate, which increases the workload of users.

[0003] The existing lost foam molds have certain disadvantages when used. First, after a long time of use on the display screen, scratches are likely to occur on the surface, which affects the clarity of the display screen and is not convenient for people to view data. Secondly, when placed, the stability Poor, when a collision or tilt event occurs, the yield rate of the component is greatly reduced, the heat dissipation effect is poor, the molding speed of the component is reduced, the control is more complicated, and multiple people are required to operate, which increases the user's workload. The work burden has brought certain adverse effects. Therefore, we propose a lost foam mold for the ejection device of the motor shell
