[0034] Figure 3 is a perspective view of the upper mold in the embodiment.

[0035] As shown in the figure, Figure 3 , the upper mold 10 includes an upper mold plate 11, a plurality of upper mold guide columns 12, and a plurality of workpiece positioning columns 13.

[0036] The upper mold plate 11 is generally rectangular plate-shaped, a circular through mold core assembly hole 111 is formed in the middle, the surface in the middle of the lower mold forms an upper mold locking groove 112, and the opposite sides form a plurality of upper mold lug hole groups 113. The upper mold plate 11 also has four through upper mold guide column mounting holes 114 and two through pressing column mounting holes 115.

[0037] Among them, the cross section of the upper mold locking groove 112 in the thickness direction of the upper mold plate 11 is a rectangle with rounded corners, and along the thickness direction, the cross-sectional size gradually changes, the size of the slot is larger than the size of the groove bottom, so the upper mold locking groove 112 has four inner side surfaces inclined relative to the thickness direction, which is denoted as the upper mold locking surface 112a.

[0038] Four guide pillar mounting holes 114 are respectively located at four corners of the upper die locking groove 112. The upper die guide pillar 12 comprises two coaxially arranged cylindrical portions with different diameters, and the overall length of the upper die guide pillar 12 is greater than the thickness of the upper die plate 11. After assembly, the larger-diameter end of the upper die guide pillar 12 is embedded in the upper die guide pillar mounting hole 114 and fixed by a fastener (screw), and the smaller-diameter end of the upper die guide pillar 12 protrudes outside the lower surface of the upper die plate 11.

[0039] Two pressing pillar mounting holes 115 are arranged along a diagonal line of the upper die plate 11, and are closer to the middle of the upper die plate 11 than the two upper die guide pillar mounting holes 114 on the diagonal line. The workpiece positioning pillar 13 is in a cylindrical shape, and the overall length of the workpiece positioning pillar 13 is slightly less than the thickness of the upper die plate 11. After assembly, one end of the workpiece positioning pillar 13 is embedded in the pressing pillar mounting hole 115 and fixed by a fastener, and the other end of the workpiece positioning pillar 13 is located in the upper die locking groove 112 and does not exceed the lower surface of the upper die plate 11. The outer end surface of the other end of the workpiece positioning pillar 13 is a plane perpendicular to the thickness direction of the upper die plate 11, which is used to cooperate with the corresponding hole on the upper bottom plate of the preform placed in the mold 100 during mold closing, so as to realize the accurate positioning of the preform in the mold.

[0040] In an alternative, a larger number of upper die guide pillars 12 and workpiece positioning pillars 13 can be provided as needed.

[0041] Figure 4 is a perspective view of the mold core in this embodiment.

[0042] As shown in Figure 4 , the mold core 20 comprises four matching sliders 21 and a plurality of wear-resistant blocks 22. The four sliders 21 can be combined into one body or separated from each other.

[0043] Figure 5 is a perspective view of the slider in this embodiment, Figure 6 is a perspective view of the slider at different angles in this embodiment.

[0044] As shown in Figure 5 and Figure 6 , the slider 21 is in the shape of an irregular block, one side of which in the width direction is relatively flat and longer, which is the outer side 211 of the slider; the other side is in the shape of a circular arc and shorter, which is the forming side 212 of the slider. The two ends of the slider 21 in the length direction are approximately wedge-shaped, each having an outer end surface inclined with respect to the length direction of the slider, for splicing with other sliders 21.

[0045] The outer side 211 of the slider has an outer side surface, which includes a main side surface 211a perpendicular to the width direction of the slider and an upper side surface 211b inclined with respect to the width direction, the inclination angle of the upper side surface 211b being substantially the same as that of the upper die locking surface 112a. As viewed from the side, the lower part of the slider 21 is flat in the thickness direction, and the upper end is inclinedly received. Two recessed wear-resistant piece mounting grooves 2112 are formed at the upper side surface 211b, which are long and shallow, the cross section in the depth direction is a rectangle with rounded corners, the surface direction of the groove bottom is substantially the same as that of the upper side surface 211b, that is, inclined upward, and the groove bottom further has a threaded hole. Two locking and matching grooves 2113 are formed at the lower end of the main side surface 211a, the surface direction of the groove bottom is inclined with respect to the main side surface 211a, and is inclined in a direction different from that of the upper side surface 211b. There is a further recessed wear-resistant piece mounting groove 2112 at the groove bottom of the locking and matching groove 2113, and the surface direction of the groove bottom is inclined downward. In this embodiment, the shapes and sizes of the plurality of wear-resistant piece mounting grooves 2112 are consistent.

[0046] The wear-resistant block 22 is a flat strip-shaped block, the cross-sectional shape in the thickness direction is matched with the wear-resistant piece mounting groove 2112, the thickness is slightly greater than the groove depth, and the wear-resistant block 22 has mounting holes at both ends and the middle part, respectively, which correspond to the threaded holes at the groove bottom of the wear-resistant piece mounting groove 2112. Therefore, the wear-resistant block 22 can be embedded in the wear-resistant piece mounting groove 2112 and fixed by a plurality of bolts. The outer end part of the wear-resistant block 22 mounted in the mounting groove of the upper side surface 211b protrudes outside the upper side surface 211b, and the outer end part of the wear-resistant block 22 mounted in the mounting groove at the bottom of the main side surface 211a protrudes outside the groove bottom surface of the locking and matching groove 2113.

[0047] The middle part of the slider outer side 211 has a recessed exhaust matching groove 2111, which extends along the thickness direction of the slider. The middle part of the slider 21 also has a plurality of through exhaust holes 215, which extend along the width direction of the slider 21 and communicate with the exhaust matching groove 2111 at one end. In addition, two hook holes 216 are also provided on the main side surface 211a.

[0048] The forming side 212 has two curved flake-shaped protrusions, the outer end surface of the protrusion is a forming surface 212a, which is a circular arc surface, and there is a gap between the two forming surfaces 212a. Each forming surface 212a is also a certain distance away from the edge of the slider 21, so that when the four sliders 21 are combined, a cylindrical cavity is formed in the middle part, the side walls of the cavity are spaced apart and have a plurality of forming surfaces 212a, and all the forming surfaces 212a are substantially located on a unified circular surface. The other end of the exhaust hole 215 is located between the two adjacent forming surfaces 212a.

[0049] Both the upper and lower ends of slider 21 are stepped. Taking the upper end 213 of slider as an example, there is a strip-shaped protrusion 2131 on the side of the upper end near the outer side 211 of slider, so that the upper end has two upper end faces at different heights, referred to as the inner end face 213a and the outer end face 213b of upper end, respectively. The inner end face 213a of upper end is an arc-shaped plane, and the outer end face 213b of upper end is a long strip-shaped plane. Both end faces are perpendicular to the thickness direction of slider 21. The lower end 214 of slider has a similar structure. In addition, there is a guide groove 2141 in the middle of the bottom surface of slider. The groove extends and runs through the width direction of slider 21. Its cross-section in the extension direction is trapezoidal, and the groove opening size is larger than the groove bottom size. There are also oblique guide post holes 2142 at both ends of the bottom surface of slider. From the bottom surface of slider to the middle of slider, the oblique guide post holes 2142 extend obliquely upward toward the outer side 211 of slider. Its cross-section in the extension direction is circular.

[0050] In this embodiment, the four sliders 21 include two first sliders 21a and two second sliders 21b. During assembly, the first sliders 21a and second sliders 21b are spaced apart, meaning the two first sliders 21 are located on opposite sides of the mold core 20. The structure of the two first sliders 21a is as described above. The two second sliders 21b further have two circular cross-section guide post mating holes 2132, respectively formed at both ends of the strip-shaped protrusion 2131 at the upper end of the slider, used to mate with the upper mold guide post 12 and provide guidance during mold closing.

[0051] like Figure 4 As shown, when the four sliders 21 are combined, a cylindrical cavity is formed on its inner side. The strip-shaped protrusions 2131 at the upper end of the four sliders 21 form a roughly rectangular protrusion edge. The inner end faces 213a at the upper end are basically coplanar. A roughly rectangular plate-shaped receiving groove is formed between the four strip-shaped protrusions 2131 and above the four inner end faces 213a at the upper end. A similar receiving groove is also formed at the lower end of the four sliders 21. These grooves can be used to receive the upper and lower ends of the rectangular plate-shaped preform and to position it. The cylindrical cavity can be used to receive the middle part of the cylindrical preform.

[0056] The middle portions of the four edge portions of the lower die plate 31, which are towards the upper surface of the upper die, are respectively provided with guide piece installation grooves 313, which are strip-shaped shallow grooves, the extension direction of the grooves is perpendicular to the edge length direction of the corresponding edge portion, and the groove bottom further has a plurality of threaded holes. The extracted guide piece 32 is a strip-shaped block matched with the guide groove 2141, and is fixed in the guide piece installation groove 313 through a plurality of screws, and the upper end thereof protrudes outside the upper surface of the lower die plate 31.

[0057] Each edge portion of the lower die plate 31 is also respectively provided with two locking block matching holes 314 and two inclined guide pillar sleeve holes 315, which are located on both sides of the guide piece installation groove 313 of the edge portion, wherein the locking block matching hole 314 is relatively closer to the edge. The locking block matching hole 314 is a through hole with a rectangular cross section with rounded corners, the length direction of which is consistent with the edge length direction of the corresponding edge portion, and in the thickness direction of the lower die plate 31, the locking block matching hole 314 has a gradually changing hole diameter, which is larger at one end of the lower surface of the lower die plate 31. The inclined guide pillar sleeve hole 315 is a strip-shaped through hole with circular arc-shaped ends, the length direction of which is perpendicular to the edge length direction of the corresponding edge portion.

[0058] In addition, a plurality of groups of lower die lug holes 316 are respectively provided on the opposite sides of the lower die plate 31.

[0059] Figure 8 is a perspective view of the lower die locking mechanism in this embodiment.

[0060] As shown in Figure 8 , the lower die locking mechanism 40 is used to match with the lower die 30 to realize locking of the mold, which includes a lower die backing plate 41, four lower die guide pillars 42, eight locking blocks 43, and eight inclined guide pillars 44.

[0061] Figure 9 is a perspective view of the lower die backing plate in this embodiment.

[0062] As shown in Figure 9 , the lower die backing plate 41 is also generally rectangular plate-shaped, and lower die guide pillar installation holes 411, which are counterbores, are respectively formed in the four corner portions thereof. The lower die guide pillars 42 are cylindrical, one end of which is fitted into the lower die guide pillar installation hole 411 and is fixed by a fastener, and the other end thereof protrudes above the upper surface of the lower die backing plate 41, and the protruding height is greater than the thickness of the lower die plate 31.

[0063] The upper surface of each of the four edges of the lower mold base plate 41 is provided with two locking block mounting grooves 412, which are elongated grooves. The length direction of the groove is consistent with the side length direction of the corresponding edge, and the cross-section of the groove in the depth direction is a rectangle with rounded corners. Each locking block mounting groove 412 is also provided with two through locking block fixing holes 413. The lower end of the locking block 43 is fitted into the locking block mounting groove 412 and is fixed by fasteners provided in the locking block fixing holes 413.

[0065] like Figure 10 As shown, the locking block 43 includes an integrally formed main body block portion 431, a locking block portion 432, and a fitting block portion 433.

[0066] The main block 431 is block-shaped, and its cross-section in the width direction of the locking block 43 is trapezoidal. The locking block 432 extends upward from the upper end of the main block 431, and its cross-sectional dimensions gradually decrease along the extension direction. Therefore, a plane inclined relative to its height direction is formed on one side of the upper end of the locking block 32. This plane is the lower mold locking surface 432a.

[0067] The fitting block portion 433 extends downward from one side of the lower end of the main block portion 431 and is disposed on the same side as the lower mold locking surface 432a, so that the lower end of the locking block 43 is stepped.
