[0042] For example, Figures 1-17As shown, the embodiment of the utility model provides a fine collection mould, including lower mould 15 and with the upper mould assembly of lower mould 15 is adapted, the upper mould assembly includes upper mould plate 1, the lower end surface of upper mould plate 1 is connected with shell 3, shell 3 is fixedly connected with upper mould plate 1 through first screw 2, the bottom of shell 3 is provided with lower baffle 16, the inside of shell 3 is provided with multiple slideway 5, the both sides boss of slideway 5 is provided with slideway batten 13, slideway batten 13 is fixedly connected with slideway 5 through fourth screw 14, to form T type sliding groove, T type key 8 is slidably connected in slideway 5, T type key 8 is connected with sliding block 19, slideway 5 is obliquely arranged, T type key 8 is slid upward relative to slideway 5 simultaneously, will drive sliding block 19 and move inward, the inside of sliding block 19 is provided with fine collection module 20, fine collection module 20 is fixedly connected with sliding block 19 through sixth screw 21.

[0043] As Figure 1 and Figure 5 As shown, the shell 3 is circular, the inside surface of the shell 3 is divided into multiple facets, the number of the facets is odd, and the number of the facets is 19 in this embodiment, and more odd numbers can be set according to the diameter. The slideway 5 corresponds to the facets one by one, and the number of the fine collection modules 20 corresponds to the number of the slideways 5. The slideway 5 is fixedly connected with the shell 3 through the second screw 6, and the facets of the shell 3 are inlaid with first pins 7 for positioning. The T-shaped key 8 is fixedly connected with the sliding block 19 through the third screw 9, and the outer surface of the sliding block 19 is inlaid with a second pin 10.

[0044] As Figure 1 and Figure 3 As shown, the inside of the shell 3 is provided with an annular groove 31, the annular groove 31 is located above the facets, the annular groove 31 is provided with a limiting block 22, the limiting block 22 is fixedly connected with the shell 3 through a seventh screw 23, and the limiting block 22 corresponds to the slideway 5 one by one. The limiting block 22 positions the slideway 5. As shown in Figures 14-17 As shown, one side of the limiting block 22 is a circular arc surface matched with the annular groove 31, and the lower end of the limiting block 22 is a wedge shape matched with the inclination angle of the slideway 5, that is, the lower end surface of the limiting block 22 is matched with the upper end surface of the slideway 5, so as to strengthen the fixation of the slideway 5 and prevent the second screw 6 from being broken under stress, thereby improving the stability and reliability of the mold structure.

[0045] As Figure 1 and Figure 3As shown, the housing 3 has multiple oil injection holes 33, the number of which corresponds to the number of slide rails 5. Each oil injection hole 33 penetrates the side wall of the housing 3 and is located above the slide rails 5. An oil nozzle 4 is connected to the outer end of each oil injection hole 33. A V-shaped groove 32 is formed on the outer surface of the housing 3, and the oil nozzle 4 is located within the V-shaped groove 32. Figure 10 As shown, the slide 5 is provided with an oil passage.

[0046] like Figure 8 As shown, the outer bottom end of the fine-tuning module 20 is provided with a boss 202 to prevent defects such as cracks from occurring during localized heat treatment due to the large outer diameter of the seat ring steel end. Figure 6 As shown, the inner side of the slider 19 is provided with a slot 193 that matches the boss 202.

[0047] like Figure 8 As shown, the outer center of the fine collection module 20 is provided with a module protrusion 201, such as... Figure 6 As shown, the inner side of the slider 19 is provided with a slider groove 192 that matches the module protrusion 201.

[0048] like Figure 1 and Figure 6 As shown, the outer surface of the slider 19 is an inclined surface adapted to the T-key 8. A slider protrusion 191 is provided at the bottom of the outer surface of the slider 19, and the T-key 8 is secured to the slider protrusion 191 to strengthen the fixation of the T-key 8. Therefore, when the slider 19 is subjected to pressure transmitted by the T-key 8, the third screw 9 used to connect the slider 19 will not break, improving the stability and reliability of the mold structure.

[0049] like Figure 1 As shown, the lower support plate 16 is connected to the housing 3 by a fifth screw 17. Multiple support plate top posts 18 are spaced between the lower support plate 16 and the housing 3, and the number of support plate top posts 18 corresponds to the number of slide rails 5. By setting the support plate top posts 18, the stroke of the slider 19 is increased, and the overall weight of the mold is reduced.

[0050] The working process of the precision collection mold provided by this utility model is as follows:

[0051] First, the workpiece to be processed is placed on the lower mold 15 and fitted on the outside of the forming part. Then, the upper mold assembly is moved down so that the finishing module 20 falls on the lower mold 15. The upper mold assembly is moved down further, and the slide 5 slides down relative to the T-key 8 and the slider 19. At the same time, the slider 19 moves inward, causing the finishing module 20 to retract inward to finish the workpiece.

[0052] In the scheme, the number of the fine collecting modules is odd and large, the roundness of the fine collecting seat ring product is good, and the size precision is high; the shell and the sliding block of the fine collecting die will not be abraded, only the keys and the sliding way produce friction, so only the keys and the sliding way need to be replaced after abrasion, the die consumption cost is saved; the fixing of the T-shaped key is strengthened through the setting of the sliding block protrusion, the screw breakage is prevented, and the stability and reliability of the die structure are improved; the sliding way and the key are lubricated through the setting of the oil way, and the service life of the die is improved.
