After molding, it is necessary to open the mold of the flipping member 22 and the bottom holder body 21 to take out the molded glassware. When it is necessary to flip, the protrusion 221 cooperates with the arc surface on the arched portion 11, so that the flipping member 22 rotates around the rotating axis to complete the mold opening work, so that the glassware 3 clamped on the glass bottom holder clamping mechanism 2 can be separated from the glass bottom holder clamping mechanism 2.

[0003] However, with the progress of use, the rotating shaft between the flip piece 22 and the base body 21 will inevitably wear out, causing the flip piece 22 to move downward relative to the base body 21, resulting in the flip piece 22 and the base body 21 cannot be completely molded together, and a gap will appear. During the blowing process, the glass raw material overflows through the gap, causing ridges to appear on the surface of the blown glassware, affecting the molding quality of the glassware. At this time, the rotating shaft needs to be replaced, increasing production costs. Utility Model Content

[0028] Example 1

[0029] The glassware forming device comprises a frame 1, such as Figure 1As shown, the frame is provided with an arched portion 11, the arched portion 11 is provided with an arc surface, the frame 1 is rotatably provided with a turntable 12, and the turntable 12 is provided with a plurality of stations. In this scheme, six stations are provided, and each station is provided with a molding mechanism 13 and a glass bottom support clamping mechanism 2. The molding mechanism 13 includes a connecting member 131 and a molding member 132, as shown in FIG. Figure 2 As shown, the forming member 132 is slidably disposed inside the connecting member 131 , and the rotation method of the turntable 12 and the forming mechanism 13 are prior arts, which will not be described in detail herein.

[0030] Embodiment 1 is basically as attached Figure 3-6 As shown, Figure 3-6 The glass bottom support clamping mechanism shown in the figure includes a bottom support body 21, a flip member 22, a rotating shaft 2122, a mold clamping unit and a rotating assembly, such as Figure 5 As shown, the base body 21 includes an integrally formed first base, a first mounting portion and a second mounting portion. The first base is a semicircular ring structure, and a first inclined surface 211 is provided at the free end of the semicircular ring structure. The first mounting portion is opposite to the base, and is provided with a mold hole 213 and a rotation clamping hole 214. The second mounting portion connects the first mounting portion and the base, and is provided with a threaded hole 2121. The rotating shaft 2122 is fixed to the base body 21 through the threaded hole 2121. The lower end of the connecting member 131 is welded or threadedly connected to the rotation clamping hole 214, preferably threadedly connected.

[0031] like Figure 5 As shown, the flip member 22 includes an integrally formed second supporting bottom and a flip connection portion, the second supporting bottom is a semicircular ring corresponding to the first supporting bottom, a protrusion 221 is welded to one end of the second supporting bottom away from the flip connection portion, a second inclined surface 223 is provided at the free end of the second supporting bottom, the second inclined surface 223 is adapted to the first inclined surface 211, a through hole is provided on the flip connection portion, the diameter of the through hole is adapted to the rotating shaft 2122, when in use, the rotating shaft 2122 passes through the through hole to rotate the flip member 22 and set it on the bottom supporting body 21, the mold-matching state of the first inclined surface and the second inclined surface is as shown in FIG. Figure 3 As shown, the first inclined surface 211 and the second inclined surface 223 do not completely cover the free ends of the first bottom supporting portion and the second bottom supporting portion. The vertical section reserved in the upper portion limits the mold closing state of the flip member 22 to ensure that the mold closing state of the flip member 22 will not be over-flipped.

[0032] At the same time, in order to prevent the flip member 22 from being worn before the rotating shaft 2122 during use, the hardness of the flip member 22 should be greater than the hardness of the rotating shaft 2122 when selecting the material.

[0033] The mold clamping unit includes a mold clamping part 241 and a cylinder. A guide rod 2411 is welded to the mold clamping part 241. Figure 3 , Figure 4As shown, the clamping piece 241 is slidably arranged below the first mounting portion, and the guide rod 2411 passes through the clamping hole 213, so that the clamping piece 241 can slide up and down in the clamping hole 213 with the help of the guide rod 241. The top of the guide rod 2411 is painted red to form a red warning section (not marked in the figure). The cylinder is fixed above the first mounting portion by bolts, and the output shaft of the cylinder passes through the clamping hole 213 and is welded or threadedly connected to the clamping piece 241. In this scheme, it is a threaded connection. When the output shaft of the cylinder is extended to the longest, the red warning section should be completely located in the clamping hole 213.

[0034] When the shaft is worn, a downward force can be applied to the flip part 22 through the mold clamping part 241, and the downward force can be converted into an upward force through the action of the first inclined surface 211 and the second inclined surface 223, thereby preventing the flip part 22 from moving downward due to slight wear of the shaft 2122, affecting the molding quality of the glass product, and ultimately extending the service life of the shaft 2122 and reducing production costs.

[0035] It should be noted that when the rotating shaft 2122 is severely worn, the flip part 22 moves down too much, the first bevel 211 and the second bevel 223 are misaligned, and the flip part 22 cannot complete the mold closing with the cooperation of the first bevel 211 and the second bevel 223. When closing the mold, the red warning section partially leaks out of the mold hole 213. At this time, the operator can accurately determine which rotating shafts 2122 are severely worn and need to be replaced during the maintenance process.

[0036] The rotating assembly includes a chain 133 and six ratchets 1311. The ratchets 1311 are respectively welded to the upper ends of the connecting member 131. The chain 133 includes a middle portion and two ends. Figure 6 As shown, both ends of the chain 133 are fixed to the frame 1 by bolts or hooks, and the middle part is tangent to the ratchet 1311 respectively, so that the ratchet 1311 is driven to rotate by the rotation of the turntable 12, thereby driving the glass bottom support clamping mechanism 2 to rotate and lower the glass product 3.

[0037] Example 2

[0038] Embodiment 2 is basically the same as Embodiment 1, except that the rotating assembly includes a gear set and a servo motor, the gear set includes a first gear and a second gear meshing with each other, the gear set includes a first gear, the first gear key is connected to the connecting member 131, the servo motor is fixed to the turntable by bolts, and the second gear key is connected to the output shaft of the servo motor.

[0039] The connecting member 131 is driven to rotate by the gears and the servo motor. The servo motor has strong controllability and can adjust the rotation speed of the connecting member 131 according to demand. The flow direction and speed of the glass liquid are controlled by centrifugal force to enhance the blowing quality of the glassware 3.
