Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The core of the utility model is to provide a finishing mold, which can ensure the stability and reliability of the mold operation, ensure the dimensional accuracy of the workpiece after shaping, reduce the wear of the mold during use, and ensure the service life of the mold. Another core of the utility model is to provide a shaping device including the above-mentioned finishing mold.

[0032] The finishing mold provided by the utility model mainly includes a mold body 1 and a swelling block 2. Please refer to Figure 2 , Figure 3 , Figure 4 The inner side of the expansion block 2 can slide along the mold body 1, and the outer side of the expansion block 2 is mainly used to fit and press the end face of the workpiece 3. Here, the workpiece 3 is mainly a wheel rim, but can also be other workpieces that need to be shaped. Through the coordinated movement of the mold body 1 and the expansion block 2, and the use of the press, the rim is subjected to fine shaping operations such as extrusion and stretching to ensure the processing quality of the rim.

[0033] A plurality of pyramidal surfaces 11 are evenly distributed on the outer periphery of the mold body 1 in the axial direction thereof. Figure 4The pyramidal surfaces 11 are multiple inclined planes arranged on the mold body 1 and having inconsistent sizes at the top and bottom.

[0034] The inner side of the expanding block 2 fits with the pyramidal surface 11. When the expanding block 2 and the mold body 1 slide relative to each other, the expanding block 2 can slide up and down along the ridge direction of the pyramidal surface 11 on the mold body 1. The rim is sleeved on the outer side of the expanding block 2. During the sliding process of the expanding block 2, the inner end surface of the rim can be shaped.

[0035] In this embodiment, the specific distribution form of the pyramidal surface 11 and the direction angle of the cone line are not limited.

[0036] During the sliding process of the expansion block 2, the expansion block 2 always fits with the pyramid surface 11, that is, the two always maintain a good surface contact relationship, ensuring the reliable stability of the mold during operation, ensuring the accuracy of the processing size of the workpiece 3, and improving the quality rate of the workpiece. Through the surface contact method, the sliding between the expansion block 2 and the mold body 1 is more stable and wear-resistant, reducing the wear of the mold during use, ensuring the service life of the mold, and increasing economic benefits.

[0037] The above-mentioned finishing mold includes a mold body 1 and a swelling block 2, wherein a plurality of pyramidal surfaces 11 are evenly distributed on the outer periphery of the mold body 1 around its axial direction, the inner side of the swelling block 2 fits with the pyramidal surface 11 and can slide along its cone line direction, and the outer side of the swelling block 2 is used to fit with the workpiece and press the end face of the workpiece; during the shaping operation, the workpiece 3 is sleeved on the outer side of the swelling block 2, and the swelling block 2 slides up and down along the cone line direction of the pyramidal surface 11 to position and shape the workpiece 3; during the relative sliding process of the swelling block 2 and the mold body 1, the contact between the two is surface contact, which ensures good adhesion between the two, ensures the stability and reliability of the mold operation, ensures the dimensional accuracy of the workpiece after shaping, reduces the wear of the mold during use, and ensures the service life of the mold.

[0038] On the basis of the above embodiment, the bottom of the mold body 1 is a cylinder, and the outer circumference of the top of the cylinder is inclined toward the axis direction of the mold body 1 to form a pyramid surface 11.

[0039] Please refer to Figure 4 The bottom of the mold body 1 is a cylinder, that is, the bottom surface is a plane, which is convenient for processing and easy to install with other parts of the mold, ensuring good coaxiality during mold operation and ensuring reliable stability of the operation.

[0040] The outer circumference of the top of the cylinder is inclined toward the axial direction close to the mold body 1 to form a pyramidal surface 11. The inclination here refers to an upward inclination, that is, the bottom of the pyramidal surface 11 starts from the cylinder, and the top of the pyramidal surface 11 ends at the axial direction close to the mold body 1. The pyramidal surface 11 forms an acute angle with the axis of the mold body 1.

[0041] It should be noted that the top of the mold body 1 is not pointed, and the top and bottom of the mold body 1 are both flat structures, which is convenient for installation and stable and reliable shaping operations.

[0042] Based on any of the above embodiments, the angle between the ridgeline of the pyramid surface 11 and the axis of the mold body 1 is 14° to 16°.

[0043] Please refer to Figure 2 , Figure 4 As a preferred embodiment, the angle between the ridgeline of the pyramid surface 11 and the axis of the mold body 1 is 14° to 16°, and the angle between the ridgeline of each pyramid surface 11 and the axis of the mold body 1 is preferably set to 14° to 16°, to ensure the overall strength and stability of the mold body 1, and to ensure the reliable stability of the cooperation between the mold body 1 and the expansion block 2.

[0044] It should be noted that the length of the ridgeline of the pyramid surface 11 needs to be designed in combination with the size of the expansion block 2 and the length required for sliding.

[0045] Of course, 14°~16° can also be flexibly changed, such as 20°, 25°, etc., and can be flexibly designed based on actual conditions.

[0046] On the basis of any of the above embodiments, the bottoms of the multiple pyramidal surfaces 11 have arc surfaces for facilitating the positioning of the expansion block 2 , and the tops of the multiple pyramidal surfaces 11 are connected to a polygonal surface.

[0047] Please refer to Figure 2 , Figure 4 The bottoms of the multiple pyramidal surfaces 11 all have an arc surface that is convenient for positioning the rising block 2. The bottom of the rising block 2 fits on the arc surface, which is the lower limit position of the sliding of the rising block 2, that is, the initial position of the rising block 2.

[0048] The tops of the multiple pyramidal surfaces 11 are connected to a polygonal surface, that is, the top of the mold body 1 is a polygonal surface, and the top of each pyramidal surface 11 has a common edge with the polygonal surface. The polygonal surface can be a regular polygon or a non-polygon.

[0049] On the basis of any of the above embodiments, a plurality of pyramidal surfaces 11 are closely arranged along the outer circumference of the mold body 1 , and two adjacent pyramidal surfaces 11 share the same edge line.

[0055] Please refer to Figure 5 The two sets of finishing dies are symmetrically arranged between the upper die plate 8 and the lower die plate 5. The polygonal end faces on the two sets of finishing dies are abutted against each other, that is, the small head ends are abutted. When the rim shaping operation is performed, the expansion block 2 slides on the two sets of finishing dies to realize the shaping operation of the rim end face.

[0056] On the basis of the above embodiment, a moving assembly 4 is further provided between the upper mold plate 8 and the lower mold plate 5 for driving the rising block 2 to slide along the cone line direction of the pyramid surface 11 .
