DETAILED DESCRIPTION

[0028] The present invention is further described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 12 As shown, in order to achieve the technical effect of "different types of molds can be replaced according to different usage requirements to cast motor housings of different sizes and models", the structure and function of a motor housing mold are described in detail below;

[0030] A motor housing mold comprises a support frame 11, a threaded disk 12 is rotatably connected to the bottom of the support frame 11, a plurality of receiving slots 13 are arranged on the support frame 11, a plurality of clamping blocks 14 are slidably connected to the bottom of the support frame 11; the plurality of clamping blocks 14 are all connected to the threaded disk 12 by threads;

[0031] A power mechanism for driving the threaded disk 12 to rotate is fixedly connected to the support frame 11, and the power mechanism is preferably a servo motor;

[0032] A bottom mold 21 is clamped between the multiple clamping blocks 14, and multiple split molds 22 are buckled on the bottom mold 21, and the multiple split molds 22 constitute a complete casting mold;

[0033] Each split mold 22 is fixedly connected to a limit bracket 23, a top plate 24 is fixedly connected to the limit bracket 23, a clamping plate 25 is fixedly connected to the limit bracket 23, and a clamping interface is provided on the clamping plate 25;

[0034] A first telescopic mechanism 31 is fixedly connected in each storage slot 13, and an L-shaped slide rail 32 is fixedly connected to the telescopic end of the first telescopic mechanism 31, and the limiting bracket 23 can slide into the L-shaped slide rail 32;

[0035] A plurality of second telescopic mechanisms 41 are fixedly connected to the support frame 11, a squeeze plate is fixedly connected to the telescopic end of each second telescopic mechanism 41, a tilting push block 42 is slidably connected to each squeeze plate, and a first compression spring is fixedly connected between the tilting push block 42 and the squeeze plate;

[0036] The extrusion plate can be pressed against the top plate 24, and the inclined push block 42 can be inserted into the card interface provided on the card plate 25;

[0037] The support frame 11 is fixedly connected with a third telescopic mechanism 61, the telescopic end of the third telescopic mechanism 61 is fixedly connected with a lifting bracket 62, the lifting bracket 62 is fixedly connected with a forming mold 63, the forming mold 63 can be inserted into the casting mold, the forming mold 63 is buckled on the casting mold, and the forming mold 63 is provided with a casting hole 64 and an exhaust hole;

[0038] The bottom mold 21, the split mold 22 and the forming mold 63 are provided with various models;

[0039] When using, Figure 1 As shown, the bottom mold 21 is placed between the four clamping blocks 14, the power mechanism is started, the output shaft of the power mechanism starts to rotate, the output shaft of the power mechanism drives the threaded disk 12 to rotate, and the threaded disk 12 drives the clamping blocks 14 to move through the threads when rotating, so that the four clamping blocks 14 are close to or away from each other, and the four clamping blocks 14 are close to each other to complete the clamping of the bottom mold 21;

[0040] The bottom mold 21 can be set to different models, and then the four clamping blocks 14 can clamp the bottom molds 21 of different models;

[0041] The split mold 22 matched with the bottom mold 21 is placed on the L-shaped slide rail 32, as shown in FIG. Figure 8 and 9 As shown, the upper end of the L-shaped slide rail 32 is open, so that the limiting bracket 23 can be placed into the L-shaped slide rail 32 through the opening set at the upper end of the L-shaped slide rail 32. The L-shaped slide rail 32 includes two parts, a vertical part and a horizontal part. The limiting bracket 23 is first placed in the vertical part of the L-shaped slide rail 32, so that the split mold 22 is placed in the receiving groove 13;

[0042] When the limiting bracket 23 falls into the horizontal part on the L-shaped slide rail 32, the split mold 22 falls into the storage groove 13. Furthermore, since the split mold 22 and the bottom mold 21 are matched, the split mold 22 is also provided with different models. In order to control the height at which the split mold 22 and the bottom mold 21 are installed relative to each other, the first telescopic mechanism 31 is started. The first telescopic mechanism 31 can be a hydraulic cylinder or an electric push rod. The telescopic end of the first telescopic mechanism 31 drives the L-shaped slide rail 32 to move, thereby adjusting the height of the L-shaped slide rail 32, and then adjusting the height of the split mold 22 and the bottom mold 21.

[0043] The second telescopic mechanism 41 is started. The second telescopic mechanism 41 may be a hydraulic cylinder or an electric push rod. The telescopic end of the second telescopic mechanism 41 drives the tilting push block 42 to move, so that the tilting push block 42 contacts the clamping plate 25. The tilting push block 42 pushes the clamping plate 25 to move, so that the limiting bracket 23 slides on the lateral part of the L-shaped slide rail 32, thereby moving the split mold 22 onto the bottom mold 21.

[0044] Furthermore, when the split mold 22 contacts the bottom mold 21, the split mold 22 generates a reverse force, the tilted push block 42 continues to move, the tilted surface of the tilted push block 42 contacts the clamping plate 25, the tilted push block 42 is pushed downward to move, and the tilted push block 42 moves forward again, so that the tilted push block 42 is clamped into the clamping interface provided on the clamping plate 25. At this time, the extrusion plate contacts the top plate 24, and the extrusion plate squeezes the top plate 24, thereby ensuring that the split mold 22 and the bottom mold 21 are connected stably.

[0045] like Figure 6 and 7 As shown, a plurality of split molds 22 are buckled on the bottom mold 21, and the plurality of split molds 22 constitute a complete casting mold. The third telescopic mechanism 61 is started, and the third telescopic mechanism 61 can be a hydraulic cylinder or an electric push rod. The telescopic end of the third telescopic mechanism 61 drives the lifting bracket 62 to move, and the lifting bracket 62 drives the forming mold 63 to move, so that the forming mold 63 is buckled on the casting mold, and the molten metal liquid is passed through the casting hole 64 between the bottom mold 21, the casting mold and the forming mold 63 for casting;

[0046] Furthermore, the molding die 63 is connected to the lifting bracket 62 by means of screws or other convenient disassembly methods, thereby facilitating the replacement of the model of the molding die 63;

[0047] After the casting is cooled, the second telescopic mechanism 41 is started, and the second telescopic mechanism 41 drives the tilting push block 42 to move, and the vertical surface of the tilting push block 42 contacts the clamping plate 25, thereby pulling the multiple split molds 22 apart, so that the split molds 22 move to the vertical part of the L-shaped slide rail 32, so that the split molds 22 can be taken out and replaced conveniently;

[0048] Furthermore, in order to reduce the generation of bubbles during the casting process;

[0049] The support frame 11 is slidably connected in the sliding bracket 51, and a shaking mechanism 52 is fixedly connected to the sliding bracket 51. The shaking mechanism 52 is in contact with the support frame 11, and a second compression spring is fixedly connected between the support frame 11 and the sliding bracket 51;

[0050] Start the shaking mechanism 52, which contacts the support frame 11. The shaking mechanism 52 may be a hydraulic cylinder or an electric push rod, or other reciprocating mechanisms that can generate reciprocating motion and are commonly used by technicians in this field. The shaking mechanism 52 drives the support frame 11 to shake, thereby reducing the generation of bubbles during the casting process.
