Referring to fig. 1, 2, 3, 4 and 5, the present embodiment provides a low pressure casting machine, which includes a casting frame body 10, wherein the casting frame body 10 includes a main frame body 11, a roll-over stand 12 disposed on the main frame body 11 in a roll-over manner, and two mold frames 13 symmetrically disposed on the roll-over stand 12, and one end shaft of the mold frame 13 is hinged on the roll-over stand 12; the main frame 11 is provided with a turnover motor unit 14, and the output end of the turnover motor unit 14 is hinged at the middle part of the turnover frame 12; the turnover frame 12 is provided with a sliding motor unit 15 for driving the die frame 13 to move towards the other die frame 13, and the turnover frame 12 is also provided with a die clamping motor unit 16 for driving the die frame 13 to turn over.
The low-pressure casting machines in the embodiment all adopt motors as driving power and are matched with the assembly of a speed reducer to obtain required power output. Then, the locking effect at any position can be realized through the mechanism transmission of the ball screw; the motor is in a standby state with low energy consumption, and a good energy-saving effect is achieved. Therefore, the motor drives the corresponding frame body to perform corresponding casting action operation, so that the casting purpose is realized.
Specifically, the main frame 11 can be locked by bolts, and then fixed on a workbench, a wall body, a stand column frame, a hanger or other equipment frame bodies, etc., so as to realize the installation of the whole low-pressure casting machine. The turnover motor unit 14 on the main frame 11 may drive the turnover frame 12 to perform turnover and swing, for example: the roll-over stand 12 is turned to a horizontal position (i.e., the die-holder 13 thereon is located at the lowest position of the entire low-pressure casting machine), or the roll-over stand 12 is turned to a vertical position (i.e., the die-holder 13 is oriented at a position in a direction of one side of the vertical direction) to achieve roll-over between the horizontal plane and the vertical plane of the vertical horizontal plane, although the roll-over angle is greater than 90 °, only the embodiment is illustrated as being turned between 90 °, and thus the roll-over angle should be understood in a broad sense.
Further, the mold frame 13 located on the roll-over stand 12 can be driven by the sliding motor unit 15, and meanwhile, the mold frame 13 can be driven to rotate by the mold closing motor unit 16, so that the molds on the mold frame 13 are relatively oriented, or the molds are rotationally separated for blanking, and the effects of mold closing and casting and mold separating and product taking of the molds installed on the mold frame 13 are achieved.

Therefore, when the servo motor is driven to perform die assembly, the ball screw mechanism is used for locking (namely, the screw rod 1532 and the rod sleeve 1531 are locked and do not rotate any more, so that the upper die and the lower die of the die are ensured to perform casting in a die assembly state), the driving energy of the motor is in a standby state with low energy consumption, the energy-saving effect is realized, and the production cost is reduced.

In operation, the mold clamping motor unit 16 drives the placing frame 132 to rotate, so that the upper mold and the lower mold of the mold are in opposite orientations, and then the sliding motor unit 15 drives one of the fixing frames 131 to move towards the other fixing frame 131, so that the mold clamping of the upper mold and the lower mold is realized, and then after casting is completed, the reverse mold separating operation is performed, and the production is repeated.
