Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1-4As shown in the figure, a high-strength, heat-resistant and deformation-proof cast steel mold includes a base 1 and a lower mold 2 arranged at the middle position of the upper surface of the base 1. An upper mold 3 is arranged on the upper surface of the lower mold 2. Four support arms 4 are arranged at the four side positions of the upper surface of the base 1. Pressing mechanisms 5 are arranged on the outer surfaces of the support arms 4. Reinforcing rings 6 are arranged outside the pressing mechanisms 5. A transmission mechanism 7 is arranged on the outer surface of the base 1 and extends to the inside. A limiting sliding groove is opened inside the base 1 for a limiting slider 75 to slide linearly inside. A pouring gate extends from the middle position of the upper surface of the upper mold 3 to the inner surface. Four grooves for the support arms 4 to slide are opened on the upper surface of the base 1. The transmission mechanism 7 includes a motor 71 fixedly connected to the outer surface of the right side of the base 1. The output end of the motor 71 is fixedly connected to a bidirectional lead screw 72. Two nut seats 73 are threadedly connected to the outer circumferential surface of the bidirectional lead screw 72. The upper surfaces of the two nut seats 73 are fixedly connected to the lower ends of the support arms 4.

The linkage mechanism 74 includes a rotating seat 741 fixedly connected to the middle position of the inner bottom surface of the base 1. The rotating seat 741 is rotatably connected to the middle outer circumferential surface of the bidirectional lead screw 72. A rotating plate 742 is rotatably connected to the upper surface of the rotating seat 741. Four linkage rods 743 are rotatably connected to the lower surface of the rotating plate 742. One ends of the left and right two linkage rods 743 are rotatably connected to the upper surfaces of the nut seats 73. One ends of the front and rear two linkage rods 743 are rotatably connected to the upper surfaces of the limiting sliders 75. The pressing mechanism 5 includes a telescopic rod 51 fixedly connected to the outer surface of one side of the support arm 4. A fastening spring 52 is arranged outside the telescopic rod 51. A protective sleeve 53 is arranged outside the fastening spring 52. One end of the telescopic rod 51 is fixedly connected to the outer surface of the reinforcing ring 6. The protective sleeve 53 is elastically designed and can undergo elastic deformation. The protective sleeve 53 can prevent sundries from being stuck inside the fastening spring 52 and can also prevent the fastening spring 52 from pinching hands.

[0022] By adopting the above technical solution, by controlling the motor 71 to drive the bidirectional lead screw 72 to rotate, the two nut seats 73 can approach each other. The two linkage rods 743 connected to the nut seats 73 can drive the rotating plate 742 to rotate.

[0025] Working principle: When using this high-strength heat-resistant and deformation-proof cast steel mold, first, before casting of the device, the control motor 71 is driven to drive the bidirectional lead screw 72 to rotate, and the two nut seats 73 can approach each other. The two linkage rods 743 connected to the nut seats 73 can drive the rotating plate 742 to rotate, and the two limiting sliders 75 can be driven to approach each other through the linkage rods 743 connected to the limiting sliders 75, so that the four support arms 4 approach each other. During the approaching process, the telescopic rod 51 and the fastening spring 52 are compressed by force, and the approaching reinforcing ring 6 can closely adhere to the outer circumferential surfaces of the lower mold 2 and the upper mold 3. By rotating the screw rod 9, the top pressing plate 11 can be driven to approach the upper surface of the upper mold 3 to press the upper surface of the upper mold 3. This is the working principle of this high-strength heat-resistant and deformation-proof cast steel mold.
