Description

Technical Field

[0001] The utility model relates to the technical field of casting moulds, in particular to a three-cylinder EPB caliper mould. Background Art

[0002] The caliper body is one of the main parts of the automobile hydraulic disc brake. After processing, it is used in conjunction with the brake piston, brake disc, friction plate, caliper bracket, etc. The caliper body is used for automobile braking and is directly related to the safety performance of the automobile. Therefore, the design standards of the caliper body have very strict requirements. At present, some high-end cars have higher and higher requirements for braking, so it is necessary to produce a large braking effect instantly. A double-cylinder and three-cylinder or above combined structure is generally adopted. The three-cylinder caliper body has an EPB structure, which is relatively complex and has high shrinkage requirements. The current caliper mold adopts a conventional production line with one mold and two pieces lying horizontally for shrinkage compensation. The riser is difficult to shrink and difficult to separate, so it is impossible to ensure that the three-cylinder EPB caliper body has stable performance and size. The current caliper mold needs to be improved. Therefore, we propose a three-cylinder EPB caliper mold. Utility Model Content

[0018] 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 of the embodiments.

[0019] Embodiment 1, as Figure 1-2As shown, the utility model provides a technical solution: a three-cylinder EPB caliper mold, including a pouring cup 1, a filter structure 2 is connected and installed at the bottom output end of the pouring cup 1, a runner 3 is connected and installed at both ends of the filter structure 2, the output port of the runner 3 is connected and installed with a horizontal runner 4 which is perpendicular to the pouring cup 1, and both sides of the horizontal runner 4 are connected and installed with a riser group, the riser group is composed of two parallel risers 7, and the output end of the riser group is connected with the inner cavity of the casting sand core;

[0020] The filter structure 2 is a three-way frame structure, and a filter screen is embedded in the inner cavity of the filter structure 2. The filter screen is made of ceramic.

[0021] In a specific embodiment of the present invention, the input end of the pouring cup 1 is used to pour metal pouring liquid. When the metal pouring liquid passes through the filtering structure 2, the ceramic filter screen of the filtering structure 2 is used to filter the refractory metal blocks, sand particles, reaction products of metal treatment, other slag and oxides in the furnace and the ladle. The ceramic filter screen is a frame structure, and the length * width * thickness of the frame is 60mm * 60mm * 15mm. The filter screen is a porous frame structure and matches the shape of the internal cavity of the filtering structure 2. The filtered metal pouring liquid passes through the horizontal runner 4, the second layer horizontal runner pressure edge 5, and the water inlet runner. 6, riser 7, riser diameter 8, and finally flow into the inner cavity of the casting sand core, and form the shape of the casting 9 after cooling. Three cylindrical sand cores consistent with the inner diameter of the three cylinders of the casting 9 need to be placed in the inner cavity of the casting sand core to form the three cylinders of the casting 9. The mold has four pieces, two on each side, and the castings are arranged horizontally. Each casting is synchronously transported with molten metal by two risers. Two risers simultaneously feed a casting sand core to ensure that the casting is fully fed and no shrinkage is achieved. The pouring time of each casting sand core is 16.0S, and the amount of molten iron is 65KG, which can achieve mass production and improve the stability of casting quality.

[0022] In the preferred technical solution, a second-layer cross runner edge 5 and a water inlet runner 6 are sequentially connected between the cross runner 4 and the riser 7. The input end of the second-layer cross runner edge 5 is connected to the cross runner 4, and the output end of the water inlet runner 6 is connected to the riser 7. The runner edge helps to evenly flow and fill the metal material, reduces the risk of shrinkage holes and cracks generated during metal cooling, and improves the density and mechanical properties of the casting. The runner edge can apply pressure to the metal material, eliminate pores, inclusions and other defects on the metal surface, make the surface of the casting smoother and flatter, and improve its appearance quality and processing performance. The runner edge can reduce the impact and friction of the metal liquid on the mold during the flow, reduce the wear and damage of the mold, and extend the service life of the mold.

[0023] In the preferred technical solution, a riser diameter 8 is provided at the point where the output end of the riser group is connected to the inner cavity of the casting sand core. The riser is provided in the metal casting mold to facilitate the discharge of gas and impurities, and is also beneficial to reduce the pores and inclusions formed in the metal liquid during the solidification process. The setting of the riser diameter has an important influence on the quality and production efficiency of the casting. The riser diameter 8 is set in the processing area of ​​the casting, which is convenient for eliminating the subsequent process of grinding the riser diameter, and helps to improve the yield.

[0024] In the preferred technical solution, the inner shape of the inner cavity of the casting sand core matches the outer shape of the casting 9. The casting 9 is provided with three horizontally arranged cylinders. A four-claw seat is provided at one end of the casting 9 that is away from the cylinder body. Three through holes are opened in the middle of the four-claw seat. The three through holes are respectively aligned with the center positions of the three cylinders and the through holes are consistent with the inner diameter size of the cylinder body. The inner cavity of the casting sand core is provided with a three-core head that matches the outer shape of the four-claw seat in the axial diameter area of ​​the casting 9. During the molding process of the molten metal flowing into the inner cavity of the casting sand core, the initially shaped casting can cooperate with the three-core head in the inner cavity of the casting sand core, which can reduce the probability of the casting sand core running off.

[0025] To summarize, the present embodiment provides a three-cylinder EPB caliper mold. In the detailed technical solution, a horizontal line base plate mold is provided. This mold can solve the shrinkage problem of the brake base plate to ensure the performance and size of the brake base plate. In the horizontal line design, the mold forms four castings in one mold, two on each side, and the castings are arranged horizontally. Each two risers compensate for the shrinkage of one casting and each piece has a sand core to ensure that the casting is fully compensated for and no shrinkage is achieved. Each mold is poured for 16.0S and the amount of molten iron is 65KG. Mass production can be achieved to improve the quality stability of castings. A three-core head is used to position the shaft diameter to prevent the sand core from deviating. The riser diameter is in the processing position and basically no polishing is required subsequently, so mass production can be achieved to improve the quality stability of castings.
