Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0036] like Figures 1-6 As shown, this embodiment of the invention provides a polishing fixture for a glass bottle mold. The polishing fixture includes: a mounting base 1, a vertical partition 2 fixed to the top of the mounting base 1, clamping plates 3 disposed on the front and rear sides of the vertical partition 2, and a pressure plate 4 disposed above the vertical partition 2. The vertical partition 2 is detachably connected to the two clamping plates 3; the vertical partition 2, in conjunction with the two clamping plates 3, clamps the two half-molds 5 respectively. It should be understood that the clamping plate 3 on the front side of the vertical partition 2 clamps the half-mold 5 on the front side of the vertical partition 2, and the clamping plate 3 on the rear side of the vertical partition 2 clamps the half-mold 5 on the rear side of the vertical partition 2. In existing glass bottle molds, the half-molds 5, in addition to being used for forming glass bottles, also have semi-circular grooves for accommodating a bottom mold 6. When the semi-circular grooves of the two half-molds 5 are engaged, they limit the outer peripheral surface and the upper and lower end faces of the bottom mold 6. It should be noted that the two half-molds 5 separated by the vertical partition 2 can still maintain the limitation on the upper and lower end faces of the bottom mold 6. The pressure plate 4 is detachably connected to the mounting base 1. The pressure plate 4, in conjunction with the mounting base 1, clamps the two half molds 5 and the bottom mold 6. It should be understood that the half molds 5, in conjunction with the pressure plate 4, clamp the bottom mold 6 in the vertical direction, and the pressure plate 4, in conjunction with the mounting base 1, clamps both the half molds 5 and the bottom mold 6 in the vertical direction. The mounting base 1 has a first channel 7 that extends vertically through the mold. The lower end of the first channel 7 has an interface, and the upper end communicates with the mold cavity of the half mold 5. There is a gap between the top of the vertical partition plate 2 and the surface of the bottom mold 6 to be polished. The vertical partition plate 2 has a second channel 8 extending downward from the top and a third channel 9 extending from the second channel 8 to the left or right side.

[0037] The specific embodiments of the present application are described below. The glass bottle mold is inverted, and the bottom mold 6 of the glass bottle mold is on top. The two half molds 5 of the glass bottle mold are separated, and the two half molds 5 are attached to the front and rear sides of the vertical partition plate 2, respectively, and the bottom mold 6 is limited between the two half molds 5. The two clamping plates 3 are fixedly connected with the vertical partition plate 2, and the two half molds 5 are clamped in the front-rear direction. Then, the pressing plate 4 is fixedly connected with the mounting seat 1, and the two half molds 5 and the bottom mold 6 are clamped in the up-down direction. The interface at the bottom of the mounting seat 1 is communicated with the discharge port of the abrasive flow polishing machine, and the abrasive flow polishing machine is started. The abrasive flow polishing machine extrudes the abrasive flow into the mold cavity of the half mold 5, and polishes the cavity wall of the half mold 5. Then, the abrasive flow is extruded from the mold cavity of the half mold 5 to the bottom mold 6 from bottom to top, and the surface to be polished of the bottom mold 6 is polished. Then, the abrasive flow is extruded into the second channel 8 from the gap between the vertical partition plate 2 and the bottom mold 6, and finally extruded out from the third channel 9. The present application can complete the polishing of the half mold 5 and the bottom mold 6 of the glass bottle mold at one time, which is more convenient.

[0038] As shown in Figure 6 , Figure 9 , in one embodiment of the present application, the vertical partition plate 2 and the pressing plate 4 are provided with limiting members 10. The limiting members 10 are provided with two left and right limiting members, which are respectively detachably connected with the vertical partition plate 2. The limiting members 10 have concave curved surfaces matched with the outer circumferential surface of the bottom mold 6, and the two limiting members 10 limit the left and right sides of the bottom mold 6 to achieve positioning of the axis of the bottom mold 6. It should be understood that the two limiting members 10 are in clearance fit with the bottom mold 6, and the bottom mold 6 can be put into or taken out of the two limiting members 10 in the up-down direction. When the two half molds 5 are buckled on the front and rear sides of the vertical partition plate 2, the two half molds 5 are spaced apart by the vertical partition plate 2, and the outer circumferential surface of the bottom mold 6 loses the limiting, and the axis of the bottom mold 6 needs to be positioned by manual operation. By providing the limiting members 10, the axis of the bottom mold 6 can be quickly positioned, and the installation of the glass bottle mold is more convenient. In addition, the limiting members 10 with different inner curved surfaces of different radii can be flexibly replaced according to actual needs to adapt to the bottom molds 6 of different sizes of different glass bottle molds.

[0039] Further, as shown in Figures 7-8 , the left and right ends of the vertical partition plate 2 are respectively provided with first wing plate parts 11, and the limiting members 10 are provided with second wing plate parts 12 matched with the first wing plate parts 11. The first wing plate parts 11 and the second wing plate parts 12 are detachably connected by third bolts and third nuts. It should be understood that the first wing plate parts 11 and the second wing plate parts 12 are correspondingly provided with third mounting holes for mounting the third bolts.

[0040] As shown in Figure 5 , Figure 7 , Figure 8 , Figure 9As shown, in one embodiment of the present disclosure, the front and rear sides of the vertical partition 2 are respectively buckled with flow control members 13; the flow control members 13 and the cavity wall of the mold cavity of the half mold 5 have a space constituting a flow channel 14; the cross-sectional area of the flow control member 13 and the cross-sectional area of the mold cavity of the half mold 5 are positively correlated in the up-down direction, so that the cross-sectional area of the flow channel 14 is stable in the up-down direction; the two flow control members 13 and the vertical partition 2 are detachably connected by the fourth bolt and the fourth nut; the flow control member 13 and the surface to be polished of the bottom mold 6 have a space constituting a converging cavity 15, and the converging cavity 15 is in communication with the flow channel 14. It should be understood that the cross section of the mold cavity of the half mold 5 is semicircular, and the radius is R1, so the cross-sectional area is 0.5πR1 2 ; the cross section of the flow control member 13 is also semicircular, and the radius is R2, so the cross-sectional area is 0.5πR2 2 ; the cross-sectional area of the flow channel 14 is 0.5πR1 2 -0.5πR2 2 . Based on the shape of the glass bottle, the cross-sectional radius of the mold cavity of the half mold 5 will change in the up-down direction, and the appropriate flow control member 13 can keep the cross-sectional area of the flow channel 14 stable in the up-down direction, so that the abrasive particles flow uniformly and stably to polish the cavity wall of the mold cavity of the half mold 5. The flow control member 13 is provided with a counterbore for installing the fourth bolt / nut, and the vertical partition 2 has a fourth mounting hole corresponding to the counterbore. In addition, different flow control members 13 can be flexibly replaced according to actual needs to adapt to different half molds 5 with different mold cavities of different glass bottle molds.

[0041] Further, as shown in the drawings, Figure 5 , the flow channel 14 is coaxial with the converging cavity 15 and the bottom mold 6; the second channel 8 corresponds to the axis of the bottom mold 6. It should be understood that the abrasive particles flow will converge from the outside to the inside along the converging cavity 15, and squeeze into the second channel 8 corresponding to the axis of the bottom mold 6, thereby ensuring sufficient polishing effect on the surface to be polished of the bottom mold 6.

[0042] As shown in the drawings, Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown in the embodiment of the present application, the vertical partition plate 2 and the mounting base 1 are filled with an adjusting plate 16, the front and back sides of the adjusting plate 16 are flush with the front and back sides of the vertical partition plate 2, the left and right ends of the adjusting plate 16 extend from between the two half molds 5, the left and right ends of the vertical partition plate 2 have a horizontal plate part 17, and the horizontal plate part 17, the adjusting plate 16, and the mounting base 1 are detachably connected through a fourth bolt and a fourth nut. It should be understood that for different glass bottle molds, when the cavity height of the half mold 5 is different, the adjusting plate 16 with an adaptive height can be flexibly replaced, thereby being applicable to abrasive flow polishing of different glass bottle molds. In short, by replacing the limiting part 10, the flow control part 13, and the adjusting plate 16, different glass bottle molds can be matched to achieve abrasive flow polishing of different glass bottle molds.

[0043] As shown in the embodiment of the present application, Figure 1 , Figure 4 the vertical partition plate 2 and the two clamping plates 3 are provided with first mounting holes penetrating front and back, the first mounting holes are provided with first bolts 18, the first bolts 18 are sleeved with first nuts 19, and the first bolts 18 cooperate with the first nuts 19 to limit the two clamping plates 3 to achieve detachable connection of the vertical partition plate 2 and the two clamping plates 3.

[0044] Further, as shown in the embodiment of the present application, Figure 1 , Figure 4 the part of the first bolt 18 between the vertical partition plate 2 and the clamping plate 3 is sleeved with a first compression spring 20. It should be understood that when the first nut 19 is loosened, the first compression spring 20 automatically expands the vertical partition plate 2 and the clamping plate 3, so that the vertical partition plate 2 and the two clamping plates 3 maintain the same spacing, thereby facilitating the staff to insert or extract the half mold 5 of the glass bottle mold, and further making the disassembly and assembly operation of the glass bottle mold more convenient.

[0045] Further, as shown in the embodiment of the present application, Figure 1 , Figure 7 , Figure 9 , Figure 10As shown, the first wing plate part 11 is provided with a distance adjusting piece 21 on the side facing the half mold 5; the first wing plate part 11 has a limiting hole penetrating left and right; the distance adjusting piece 21 has a threaded hole corresponding to the limiting hole and is fitted with a limiting bolt 22; the limiting bolt 22 is installed in the threaded hole of the distance adjusting piece 21 after penetrating the limiting hole; the part of the limiting bolt 22 between the distance adjusting piece 21 and the first wing plate part 11 is sleeved with a second compression spring 23; the distance adjusting piece 21 is provided with a slope at the intersection of the upper surface and the side facing the half mold 5. It should be understood that after the half mold 5 is inserted between the vertical partition plate 2 and the clamping plate 3, the distance adjusting pieces 21 on the left and right sides of the half mold 5 will respectively push the half mold 5 under the action of the second compression spring 23, thereby assisting the half mold 5 to achieve rapid positioning in the left-right direction. Due to the extensibility of the second compression spring 23, the distance adjusting piece 21 can be applied to the positioning of half molds of various sizes within a certain size range; in addition, by replacing limiting bolts 22 and second compression springs 23 of different lengths, it can also be applied to the positioning of half molds of various sizes within a larger range.

[0046] Further, as shown in the drawings, Figure 1 The pressing plate 4 is provided with a second mounting hole penetrating up and down corresponding to the mounting seat 1, the second mounting hole is provided with a second bolt 24; the second bolt 24 is fixed to the mounting seat 1 in cooperation with a second nut 25; the second bolt 24 is also sleeved with a compression nut 26, which limits the top of the pressing plate 4 to realize the detachable connection of the pressing plate 4 and the mounting seat 1. It should be understood that in actual use, the present application usually only needs to perform the disassembly and assembly operation of the compression nut 26 and the pressing plate 4, and the loosening and tightening operation of the first nut 19. Specifically, insert the two half molds 5 between the vertical partition plate 2 and the clamping plate 3, and place the bottom mold 6 between the two limiting pieces 10; make the two half molds 5 buckle on the front and rear sides of the vertical partition plate 2, and tighten the first nut 19, so that the clamping plate 3 can clamp the half mold 5 in the front-rear direction; install the pressing plate 4 and tighten the compression nut 26, so that the half mold 5 and the bottom mold 6 can be clamped in the up-down direction; in this way, the installation of the glass bottle mold can be completed. Remove the compression nut 26 and the pressing plate 4, and loosen the first nut 19, so that the glass bottle mold can be loosened, and the staff can take out the glass bottle mold upward.

[0047] Although the specific embodiments of the present application are described above, those skilled in the art should understand that various changes or modifications can be made to these embodiments without departing from the principles and essence of the present application, and such changes and modifications all fall within the protection scope of the present application.
