[0003] Normally, when assembling small-volume bearings, a hammer is used to knock the bearings into the workpiece. If the workpiece is made of plastic, the bearings need to be pressed into the workpiece one by one with fingers. This manual operation is very inefficient and has low production capacity. In addition, the bearings are usually embedded in the workpiece with an interference fit. Therefore, after working for a long time, the fingers will experience various pains.

[0004] The existing patent (publication number: CN220463750U) discloses a bearing pressing machine with an adsorption assembly mounted on the piston rod of a lifting cylinder. The adsorption head corresponds to the workpiece on the work plate, and the workpiece is equipped with a mounting hole. The bearing adsorbed by the adsorption head is pressed into the mounting hole under the action of the lifting cylinder. The beneficial effect of this utility model is that by using the lifting cylinder and the adsorption assembly, the lifting cylinder provides the power for up and down pressing, pressing the bearing in the adsorption head into the mounting hole. The structure is simple, the operation is simple, and the practicality is strong. It solves the problem of low efficiency of manual assembly and will not cause any pain to the fingers.

[0005] To address the aforementioned issues, existing patents offer solutions. However, these solutions have certain limitations in practice. During the die-casting process, the high-temperature, high-pressure molten metal washes against the mold surface at high speed, especially the gate and cavity, which can easily cause mold wear, reduce mold lifespan, and increase production costs.

[0006] To address this, a wear-resistant rotor bearing die-casting mold device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a wear-resistant rotor bearing die-casting mold device, which can solve the problem that in the existing die-casting process, high-temperature and high-pressure molten metal washes against the mold surface at high speed, especially in the gate and cavity, which easily causes mold wear, reduces mold life and increases production costs.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant rotor bearing die-casting mold device, including a moving mold, a fixed mold at the bottom of the moving mold, a gate at the top of the moving mold, a protective mechanism inside the gate, and an adjustment mechanism on the opposite side of the moving mold and the fixed mold.

[0010] Preferably, the adjustment mechanism includes eight screws disposed inside both the moving mold and the fixed mold, and mounting rings are threadedly connected between the surfaces of the eight screws.

[0011] Preferably, the opposite sides of the two mounting rings extend to the opposite sides of the moving mold and the fixed mold, respectively, and each of the opposite sides of the two mounting rings is provided with an adjusting ring.

[0012] Preferably, an adjusting sleeve is fixedly connected inside the adjusting ring, and a sealing sleeve is fixedly connected to one side of each of the two adjusting sleeves.

[0013] Preferably, a connecting ring is fixedly connected to each of the two mounting rings on opposite sides, and a connecting groove is provided on each of the two adjusting rings on opposite sides, wherein the surface of the connecting ring is in close contact with the interior of the connecting groove.

[0014] Preferably, a sealing strip is fixedly connected inside the connecting groove, and the surface of the sealing strip is in close contact with the surface of the connecting ring.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A wear-resistant rotor bearing die-casting mold device includes a moving mold 1, a fixed mold 4 at the bottom of the moving mold 1, a gate 7 at the top of the moving mold 1, a protective mechanism 2 inside the gate 7, and an adjustment mechanism 3 on opposite sides of the moving mold 1 and the fixed mold 4.

[0030] The protective mechanism 2 includes a feed pipe 201, a protective sleeve 202, a mounting groove 203, a mounting plate 204, and a mounting block 205. The surface of the feed pipe 201 is fixedly connected to the interior of the protective sleeve 202. The bottom of the protective sleeve 202 extends into the interior of the mounting groove 203 and is threadedly connected to the interior of the mounting groove 203. The mounting groove 203 is opened on the top of the mounting block 205. The interior of the mounting plate 204 is fixedly connected to the surface of the mounting block 205. The bottom of the mounting plate 204 is in close contact with the top of the moving mold 1.

[0031] In this embodiment: by fixing the surface of the feed pipe 201 to the inside of the protective sleeve 202, the feed pipe 201 can be easily fixed inside the mounting groove 203 through the protective sleeve 202, and the inside of the mounting plate 204 can be fixedly connected to the surface of the mounting block 205. Under the limitation of the mounting block 205, the mounting block 205 can easily move the feed pipe 201 to the inside of the gate 7, and the mounting block 205 can easily protect the inside of the gate 7 through the feed pipe 201, thereby reducing the wear of the gate 7 during the die casting process.

[0032] Specifically, such as Figure 1 , Figure 4 As shown, the adjustment mechanism 3 includes eight screws 301 disposed inside both the moving mold 1 and the fixed mold 4, and mounting rings 302 are threadedly connected between the surfaces of the eight screws 301.

[0033] Specifically, such as Figure 1 , Figure 4 As shown, the two mounting rings 302 extend to opposite sides of the moving mold 1 and the fixed mold 4 respectively, and each of the two mounting rings 302 has an adjusting ring 305 on its opposite side.

[0034] Specifically, such as Figure 4 As shown, an adjusting sleeve 304 is fixedly connected inside the adjusting ring 305, and a sealing sleeve 303 is fixedly connected to one side of each of the two adjusting sleeves 304.

[0035] In this embodiment: by threading the interior of the mounting ring 302 to the surface of the screw 301, the mounting ring 302 can be easily fixed to the adjusting ring 305 via the screw 301, and the surface of the adjusting sleeve 304 can be fixedly connected to the interior of the adjusting ring 305. This allows the adjusting sleeve 304 to easily adjust the bearing specifications via the sealing sleeve 303, achieving the effect of convenient die casting of bearings of different specifications.

[0036] Specifically, such as Figure 5 , Figure 6 As shown, two mounting rings 302 are fixedly connected to each other on opposite sides, and two adjusting rings 305 are provided with connecting grooves 9 on opposite sides, with the surface of the connecting ring 10 in close contact with the inside of the connecting groove 9.

[0037] Specifically, such as Figure 5 , Figure 6 As shown, a sealing strip 8 is fixedly connected inside the connecting groove 9, and the surface of the sealing strip 8 is in close contact with the surface of the connecting ring 10.

[0038] In this embodiment: by making the surface of the connecting ring 10 in close contact with the inside of the connecting groove 9, the adjusting ring 305 can be conveniently positioned by the connecting groove 9 to limit the connecting ring 10, and the surface of the sealing strip 8 can be in close contact with the surface of the connecting ring 10, thereby making it convenient for the sealing strip 8 to seal the surface of the connecting ring 10, and achieving the effect of sealing the connecting ring 10.

[0039] Specifically, such as Figure 2 As shown, a connecting pipe 6 is fixedly connected to the bottom of the mounting block 205. The surface of the mounting block 205 is threadedly connected to the inside of the gate 7. The bottom of the connecting pipe 6 extends into the inside of the gate 7 and is in close contact with the inside of the gate 7.

[0040] Specifically, such as Figure 1 As shown, four limiting rods 5 are fixedly connected to the top of the fixed mold 4, and the surface of the limiting rods 5 is slidably connected to the inside of the moving mold 1.

[0041] In this embodiment: by making the surface of the connecting pipe 6 in close contact with the inside of the gate 7, the mounting block 205 can easily protect the inside of the gate 7 through the connecting pipe 6, and the surface of the limiting rod 5 can be slidably connected to the inside of the moving mold 1, thereby making it easy for the limiting rod 5 to limit the moving mold 1, achieving the effect of limiting the moving mold 1.

[0042] Working principle: During bearing die casting, two suitable mounting rings 302 are extended to opposite sides of the moving mold 1 and the fixed mold 4 according to the bearing specifications, and fixed by screws 301. This allows the mounting rings 302 to be fixed to the adjusting sleeve 304 and the sealing sleeve 303 via the adjusting ring 305. The connecting groove 9 is further fixed to the adjusting sleeve 304 via the connecting ring 10 and the sealing strip 8. This facilitates the die casting of bearings of different specifications. Then, the molten metal moves through the feed pipe 201 to the inside of the mounting block 205. Under the limit of the mounting block 205, the molten metal moves through the connecting pipe 6 to the inside of the gate 7. This allows the mounting block 205 to protect the inside of the gate 7 via the feed pipe 201, thereby reducing wear on the gate 7 during the die casting process. This solves the problem that in existing die casting processes, high-temperature, high-pressure molten metal washes against the mold surface at high speed, especially the gate 7 and cavity, which easily causes mold wear, reduces mold life, and increases production costs.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
