DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in this embodiment with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] like Figures 1 to 6 As shown, this embodiment discloses a side mold module, including a block 1, the block 1 includes a mating surface 11 and a mating module 12, the mating surface 11 is an arc surface, the block 1 includes a first side surface 13 and a second side surface 14, the first side surface 13 and the second side surface 14 are respectively located on both sides of the mating surface 11, the first side surface 13 and the second side surface 14 extend radially along the mating surface 11, when two adjacent blocks 1 are mated, the first side surface 13 of one block 1 is fitted with the second side surface 14 of the other block 1, and multiple mating surfaces 11 can be pieced together into a circle, thereby forming the rim 21 of the hub 2.

[0026] Part of the closing module 12 is located on the closing surface 11, and the closing module 12 extends along the circumferential direction of the closing surface 11. The closing module 12 includes a first mold area 121, a second mold area 122, and a third mold area 123. The first mold area 121 is located within the range of the closing surface 11, the second mold area 122 and the third mold area 123 are respectively located on both sides of the first mold area 121, and the second mold area 122 is located outside the range of the closing surface 11. The second mold area 122 includes a model surface 1221 and a first veneer 1222. The model surface 1221 is connected to the first mold area 121, that is, the model surface 1221 and the first mold area 121 form the side of the block 1 forming the rim 21.

[0027] The third mold area 123 includes a second veneer 1231. When two adjacent blocks 1 are molded together, the second mold area 122 of one block 1 is spliced with the third mold area 123 of the other block 1, and the first veneer 1222 of one block 1 is spliced with the second veneer 1231 of the other block 1. The two adjacent blocks 1 are molded together so that a part of one block 1 can contact with the other block 1, thereby increasing the contact area between the two adjacent blocks 1. When the wheel hub 2 is cast, one block 1 can better conduct heat with the two adjacent blocks 1, the temperature between the multiple spliced blocks 1 is more balanced, and the degree of deformation between the blocks 1 is also the same, which can significantly eliminate the deformation of the rim 21 caused by the different deformations between the multiple blocks 1.

[0028] The first veneer 1222 is provided with a limiting groove 1223, and the limiting groove 1223 extends along the length direction of the first veneer 1222. The second veneer 1231 is provided with a limiting strip 1232 corresponding to the limiting groove 1223, and the limiting strip 1232 extends along the length direction of the second veneer 1231. The design of the limiting groove 1223 and the limiting strip 1232 can limit the adjacent second mold area 122 and the third mold area 123 to each other, and can form a vertical limit between the second mold area 122 and the third mold area 123. At the same time, it can increase the contact area between the first veneer 1222 and the second veneer 1231, so that the adjacent two blocks are The heat conduction between the bodies 1 is better, and the temperature changes of various parts of the entire side mold are more uniform; more preferably, the contact surface of the limit groove 1223 and the limit bar 1232 is an arc surface, and the arc-shaped contact surface makes the center of the limit groove 1223 the deepest part of the limit groove 1223, and the center of the limit bar 1232 is the most protruding part. The arc-shaped concave limit groove 1223 and the protruding limit bar 1232 can minimize the contact area between the limit groove 1223 and the limit bar 1232 when the two adjacent blocks 1 are molded or separated, thereby reducing the friction and wear generated by the contact between the limit groove 1223 and the limit bar 1232.

[0029] like Figure 3As shown, the angle at which the second mold area 122 extends along the circumferential direction is a, and the angle at which the third mold area 123 extends along the circumferential direction is b. Angle a is the same as angle b, that is, the length of the second mold area 122 corresponds to the length of the third mold area 123. The second mold area 122 and the third mold area 123 between two adjacent blocks 1 can be spliced together. The angle between the second side surface 14 and the central axis of the block 1 is c. The angle at which the second mold area 122 extends out of the mold surface 11 along the circumferential direction is a. The angle a plus the angle c is less than or equal to 90 degrees. The central axis of the block 1 is the direction in which the block 1 moves away from or close to the center of the hub 2. In order to ensure that the blocks 1 can be spliced together and that the block 1 does not interfere with the hub 2 when demolded, the angle between the end face of the second mold area 122 away from the second side surface 14 and the central axis of the block 1 cannot exceed 90 degrees.

[0030] like Figure 3 、 Figure 4 As shown, this embodiment also discloses a hub side mold, including four blocks 1, which can be assembled to form a cavity for casting the hub 2, and the four blocks 1 can synchronously approach or move away from the center of the hub 2 along the radial direction. When there are four blocks 1, the angle between the first side surface 13 and the second side surface 14 of each block 1 is 90 degrees, and the maximum angle a is 45 degrees. At this time, the length of the second mold area 122 is exactly half of the mold surface 11, so that the blocks 1 can achieve the maximum contact area without interfering with each other, and the blocks 1 will not generate excessive friction with the hub 2 during demolding.

[0031] like Figures 4 to 6 As shown, the four blocks 1 can synchronously approach or move away from the center of the wheel hub 2 in the horizontal front, rear, left and right directions. The four blocks 1 can synchronously approach or move away from each other by being driven by the cylinder to achieve synchronous demolding, so as to ensure that the blocks 1 do not interfere with each other. The block 1 includes a first state and a second state. In the first state, the four blocks 1 are spliced together. In the second state, the second mold area 122 of each block 1 close to the wheel hub 2 is completely out of the vertical projection range of the wheel hub 2. When the four blocks 1 are demolded, it is necessary to ensure that the second mold area 122 of each block 1 is completely out of the rim 21 before the wheel hub 2 can be ejected from the lower mold.

[0032] like Figure 2 、 Figure 3 、 Figure 6 As shown, the first side 13 is provided with an insert 16, and the second side 14 is provided with a slot 17 corresponding to the insert 16. Adjacent blocks 1 are corresponded by the insert 16 and the slot 17, which play a role in positioning and limiting, ensuring that the positions of the final blocks 1 are stable relative to each other. The insert 16 includes a third side 161, and the third side 161 is radially parallel to the center of the mold surface 11, and the third side 161 is parallel to the moving direction of the block 1.

[0033] like Figure 1 、 Figure 2 As shown, the block 1 is a hollow structure. The block 1 includes a back side 15, which is located on the back side of the mold surface 11. The back side 15 is an arc surface. The back side 15 is provided with an annular groove 151, which extends along the length direction of the back side 15. The annular groove 151 corresponds to the rim 21 which is recessed inward from the center, ensuring that the thickness of the part of the block 1 close to the hub 2 remains uniform and can just conduct heat outward. The block 1 includes multiple heat sinks 18, which are located on the back side 15. Multiple heat sinks 18 are arranged along the length direction of the back side 15. The hollow block 1 can provide an airflow channel for the heat dissipation of the block 1, so that the cooling effect of the block 1 is better. The heat sink 18 can increase the heat dissipation area on the back side of the block 1, so that the mold has a good cooling effect.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
