[0020] The present invention will be further described with reference to the accompanying drawings.
[0021] like Figures 1 to 6 As shown, a symmetrical semi-solid metal forming machine comprises a first mold device 1, a first screw feeding device 2, a first heating device 3, a second mold device 4, a second screw feeding device 5, a second heating device 6, a clamping device 7 and a frame 8. The first mold device 1 and the second mold device 4 have the same structure, are both used for metal forming, and are symmetrically arranged. The first screw feeding device 2 and the second screw feeding device 5 have the same structure, are both installed on the frame 8, the first screw feeding device 2 and the second screw feeding device 5 are respectively connected to the first mold device 1 and the second mold device 4, and are used to convey metal raw materials, the first heating device 3 is installed on the first screw feeding device 2, and the second heating device 6 is installed on the second screw feeding device 5. The first heating device 3 and the second heating device 6 have the same structure, and are both used to heat the metal raw materials into a semi-solid state or a liquid state, and inject the semi-solid metal into the first mold device 1 and the second mold device 4 through the first screw feeding device 2 and the second screw feeding device 5 to form parts. The mold locking device 7 is connected to the first mold device 1 and the second mold device 4 respectively, and the mold locking device 7 is used for opening, closing and locking the first mold device 1 and the second mold device 4.
[0022] Casting requires first melting the metal into a liquid state in a furnace, and then transferring and pouring the liquid metal into a mold for molding. During the whole process, the high-temperature liquid metal is exposed to the air, so there are potential safety hazards and large heat losses. However, the present application melts and transports the metal in a closed spiral feeding device, which can not only improve safety, but also reduce heat losses and energy consumption. Moreover, due to the sealed pressure transport, the metal can be melted into a semi-solid state to ensure the molding requirements. There is no need to completely melt the metal into a liquid, which reduces the production temperature, greatly reduces energy consumption, and reduces production costs. Due to the use of injection molding, continuous production can be carried out, and there is no need to prepare sand cores, and parts with complex structures can be molded with high production efficiency.
[0023] The symmetrically arranged structure obtains two molding stations, which can make the structure compact while reducing the occupied area, and the overall structure is compact, and the production efficiency is improved. In addition, the symmetrical structure allows the two mold devices to share a clamping device 7, making the structure simpler and reducing the equipment cost.
[0024] Since the melting is carried out directly inside the spiral feeding device, there is no need for a front furnace, soup feeding robot and other devices, which greatly reduces the cost of the equipment, reduces energy consumption and reduces production costs.
