Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pouring and discharging devices, and more specifically, it relates to a pouring and discharging device for a PTC aluminum shell of a new energy vehicle. Background Art
[0002] The gating system is a crucial component in a die-casting mold. It is responsible for guiding the molten metal liquid from the nozzle of the die-casting machine to the cavity of the mold. The design of the gating system directly affects the filling efficiency of the casting, the gas discharge effect, and the quality of the final product. The design of the gating system needs to be optimized according to the specific shape, size, and production requirements of the casting. For example, for some castings with complex structures or uneven wall thicknesses, special gating design schemes may be required, such as adding auxiliary runners or adjusting the position and size of the gates, to ensure that the metal liquid can be filled evenly and reduce internal defects.
[0003] Currently, in the gating system for exhausting gas and slag of aluminum alloy brackets on the market, the molten aluminum alloy liquid is usually first guided into the cavity. The metal liquid passes through the sprue, which is a conical vertical channel. The hydrostatic pressure generated by the height is used to control the flow rate of the metal liquid into the mold and improve the filling ability. The speed of the metal liquid slows down in the runner, and the molten slag and gas can fully float up without entering the mold. The ingate directly introduces the metal liquid into the mold, and its position, size, and quantity can control the flow rate and direction of the metal liquid into the mold. Appropriate cold slug wells and overflow grooves are designed on the runner system to collect the relatively cold plastic wave front in the initial stage of filling.
[0004] Due to the existing inlet design during the feeding process, gas will be involved during feeding, and gas will also be involved when hitting the wall of the inlet. This will cause deformation of the casting. When the aluminum liquid is filled into the mold, the aluminum liquid will be in a turbulent flow state. During the turbulent flow process, the convex hull and island positions of the product cannot be filled, resulting in the scrapping of the casting. After the casting is completed, the wall of the sealing groove is relatively thin, resulting in poor filling and cold shut. Now, a pouring and discharging device for a PTC aluminum shell of a new energy vehicle is proposed to improve the existing problems. Summary of the Utility Model
