[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-3 The utility model provides a technical solution: a precision casting mold, including a base 1, the top of the base 1 is fixedly connected to four groups of supporting legs 2, the top of the supporting legs 2 is fixedly connected to the lower mold 3, the middle of the lower mold 3 is provided with a casting cavity 6, the top of the lower mold 3 is penetrated and slidably connected to a telescopic rod 9, the surfaces of the four groups of telescopic rods 9 are respectively provided with springs, when the pressure plate 707 presses the upper mold 4 downward, the telescopic rod 9 slides downward, at this time the spring is compressed, and when the force of the pressure plate 707 disappears, the spring is subjected to its own The elastic force drives the telescopic rod 9 to automatically reset. The top ends of the four sets of telescopic rods 9 are fixedly connected to the upper mold 4. The bottom end of the upper mold 4 is provided with a casting block so that the upper mold 4 and the lower mold 3 can cast the liquid in the casting cavity 6 without being completely closed. The middle part of the top end of the upper mold 4 is fixedly connected to the liquid injection port 5. The top end of the lower mold 3 is provided with a shaping component 7. The shaping component 7 includes a motor 701 and a six-way hydraulic cylinder 705. The output shafts of the two sets of motors 701 are respectively fixedly connected to the reciprocating screw rod 702. The reciprocating screw rod 702 is threaded. A set of scrapers 703 are connected. The reciprocating screw rod 702 can drive the scraper 703 to reciprocate under the action of the motor 701. When the reciprocating screw rod 702 moves to the right, it can trigger the shaping component 7. When the reciprocating screw rod 702 moves to the left, it can trigger the ejection component 8. The six-way hydraulic cylinder 705 is fixedly connected to the top of the lower mold 3. One end of the six-way hydraulic cylinder 705 is connected to the force rod A704 and the force rod B709 through the piston sliding. The other end of the six-way hydraulic cylinder 705 is connected to the force rod A704 and the force rod B709 through the piston sliding. There are four groups of pressure rods A706, two groups of pressure plates 707 are fixedly connected to the top of the upper mold 4, and a liquid collecting box 708 is fixedly connected to the top of the base 1. The force rods A704 and B709 are located on the movement trajectory of the scraper 703. The lower mold 3 is provided with a liquid collecting port corresponding to the liquid collecting box 708. The four groups of pressure rods A706 correspond to the four force points of the two groups of pressure plates 707 respectively. The four groups of pressure rods A706 correspond to the four force points, which increases the force area, so that the pressure plate 707 has enough force to press the upper mold 4 down.

[0021] When in use, first pour liquid from the liquid injection port 5 so that the liquid is injected into the casting cavity 6, and at the same time start the two sets of motors 701, the motor 701 drives the reciprocating screw 702, and the reciprocating screw 702 drives the scraper 703 to move rightward on the surface of the lower mold 3, thereby scraping the liquid overflowing on the surface into the liquid collecting box 708. At this time, the scraper 703 moves to the right to a certain distance, triggering the force rod A704 and the force rod B709, so that the internal liquid pressure of the six-way hydraulic cylinder 705 increases, thereby pushing out the four sets of pressure rods A706 at the same time, and exerting downward pressure on the pressure plate 707. The pressure plate 707 squeezes the upper mold 4 downward so that it contacts the lower mold 3. At the same time, the telescopic rod 9 is downward while squeezing, and the spring is elastically compressed. When the force of the pressure rod A706 is lost, the spring is driven by its own rebound force to drive the telescopic rod 9 back to the initial position, and the telescopic rod 9 drives the upper mold 4 back to the initial position, thereby facilitating the next operation and leaving a certain space for the mold to be demoulded after the operation is completed.

[0022] See also Figure 1-Figure 4 On the basis of the first embodiment, a top material ejection assembly 8 is provided at the top of the base 1, and the ejection assembly 8 includes a two-way hydraulic cylinder 802 and an inclined block 804. The two-way hydraulic cylinder 802 is fixedly connected to the top of the base 1. One end of the two-way hydraulic cylinder 802 is connected to the force rod C801 through a piston sliding connection, and the other end of the two-way hydraulic cylinder 802 is connected to the pressure rod B803 through a piston sliding connection. The bottom end of the inclined block 804 is connected to the surface of the base 1 in a sliding connection. The interior of the lower mold 3 is penetrated and slidably connected to the ejection rod 805. The bottom end of the ejector rod 805 is set as a round smooth sphere so that the ejector rod 805 can be located on the movement trajectory of the inclined block 804. The ejector rod 805 is located on the movement trajectory of the inclined block 804. An elastic spring is set on the surface of the ejector rod 805 so that the spring is compressed when the ejector rod 805 moves upward under the extrusion of the inclined block 804. When the inclined block 804 does not squeeze the ejector rod 805, the rebound force of the spring itself drives the ejector rod 805 to automatically reset, and the top of the ejector rod 805 is located inside the casting cavity 6.

[0023] During use, based on Example 1, when the scraper 703 moves to the left driven by the motor 701, the movement of the scraper 703 will squeeze the force-bearing rod C801, and the liquid pressure in the two-way hydraulic cylinder 802 increases, thereby pushing out the pressure rod B803 at the other end, and the pressure rod B803 pushes out the extruded inclined block 804, and the inclined block 804 slides on the base 1 to extrude the ejecting rod 805 upward, thereby ejecting the mold cooled and formed in the casting cavity 6, reducing the participation of staff and making the overall operation more convenient and quick.
