[0018] The present invention will be further described with reference to the accompanying drawings.

[0019] like Figures 1 to 4 As shown, a double-station semi-solid metal forming machine includes 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 and a frame 7. The first mold device 1 and the second mold device 4 have the same structure, are both used for metal forming, and are respectively installed at the two ends of the frame 7 and are also located on both sides of the frame 7; the first screw feeding device 2 and the second screw feeding device 5 have the same structure, are both installed on the frame 7, and are staggered. The first screw feeding device 2 and the second screw feeding device 5 are connected to the first mold device 1 and the second mold device 4 respectively, and the first screw feeding device 2 and the second screw feeding device 5 are used to transport metal raw materials; the first heating device 3 and the second heating device 6 have the same structure, and the first heating device 3 and the second heating device 6 are respectively installed on the first screw feeding device 2 and the second screw feeding device 5, and are used to heat the metal raw materials into a semi-solid state.

[0020] 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.

[0021] The staggered structure obtains two forming stations, which can make the structure compact and reduce the floor space, and the overall structure is compact and the production efficiency is improved.

[0022] 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.

[0023] The first mold device 1 includes a first tail plate 11, a first guide rod 12, a first fixed plate 13, a first movable plate 14, a movable mold assembly 15, a static mold assembly 16 and a first clamping cylinder 17.

The spiral feeding device can not only facilitate feeding, but also feed the material by extrusion, so that the material has a certain pressure, so that the material is injected into the mold cavity. At the same time, the spiral feeding device facilitates the heating device to heat, so that the metal is melted into a semi-solid state. The semi-solid metal can ensure fluidity and reliable molding, and reduce the production temperature, energy consumption and cost.

[0025] In order to achieve reliable driving, the first driving assembly 23 includes a first driving motor 231, a first driving gear 232 and a first driven gear 234.
