[0029] Taking the half-mold 100 on the right as an example, refer to... Figure 1 As shown, a molding cavity 110 is provided on the left side wall of the half mold 100. The left side of the molding cavity 110 is open. The inner side wall of the molding cavity 110 is provided with a bottle mouth section, a bottle neck section, and a bottle body section from top to bottom. The distance from the bottle mouth section and the bottle neck section to the axis of the half mold 100 gradually increases from top to bottom. The bottle body section is semi-cylindrical. Multiple vent holes 120 are provided inside the half mold 100. Each vent hole 120 extends in the vertical direction, and the multiple vent holes 120 are evenly distributed along the circumference of the molding cavity 110. The distance from the axis of each vent hole 120 to the inner wall of the molding cavity 110 is equal from top to bottom. That is, the shape of the vent hole 120 matches the shape of the bottle mouth section, the bottle neck section, and the bottle body section, so that the heat dissipation effect of the vent hole 120 on the molding cavity 110 is more uniform.
[0030] A connecting hole 130 is provided on the right side wall of the half mold 100. The connecting hole 130 is close to the bottom of the half mold 100 and extends in the left and right direction. An annular air inlet groove extending circumferentially along the molding cavity 110 is provided at the left end of the connecting hole 130. The annular air inlet groove connects to the bottom end of all the vent holes 120.
[0031] The top of the half mold 100 is provided with an outwardly extending snap-fit seat 140. The snap-fit seat 140 protrudes outward from the right side, front side and rear side of the half mold 100. The interior of the snap-fit seat 140 is provided with an air vent 150. The air vent 150 extends in the left and right direction. The left end of the air vent 150 is provided with an annular air vent groove extending circumferentially along the molding cavity 110.

The right end of the air vent 150 extends downward to the top wall of the snap groove 141.
[0032] Reference Figure 2 As shown, each hook 200 is provided with a screw and a round head 220. The round head 220 is located at the end of the screw and is disc-shaped. The axis of the round head 220 coincides with the axis of the screw. The hook 200 is also provided with an air inlet 210 that runs through the axis.
[0033] Reference Figure 1As shown, each connecting hole 130 is provided with an internal thread, and the screws of the two hooks 200 respectively engage with the internal threads of the two connecting holes 130. There is a space between the round head 220 of the hook 200 and the outer side wall of the half mold 100. The air inlet 210 is connected to the bottom end of all the vent holes 120 of the half mold 100 through an annular air inlet groove.
[0034] The clamp 300 includes two upper mounting brackets 310 and two lower mounting brackets 320. The two upper mounting brackets 310 are connected to the mounting brackets 140 of the two half molds 100 in a one-to-one correspondence. The two lower mounting brackets 320 are connected to the two hanging pins 200 in a one-to-one correspondence.
[0035] Each upper mount 310 is provided with an air outlet channel 311, which extends in the left and right direction. Each upper mount 310 is provided with a locking block 312 at the top, the shape of which matches the shape of the slot 141. One end of the air outlet channel 311 extends upward to the top surface of the locking block 312 as an air outlet port 3111.
[0036] Each lower mount 320 is provided with an air intake channel 321, which extends in the left and right direction. Each lower mount 320 has an arc groove 322 at its top, the shape of which matches the shape of the round head 220 of the hook 200. One end of the air intake channel 321 is provided on the side wall of the arc groove 322 as an air intake port 3211, and a sealing ring 330 is provided on the end face of the air intake port 3211.
[0037] Each air intake channel 321 is provided with a smooth section 3212 and an acceleration section 3213 from the outside air intake port 3211. The diameter of the smooth section 3212 remains unchanged, while the diameter of the acceleration section 3213 gradually decreases from the smooth section 3212 to the air intake port 3211.
[0038] The upper mounting bracket 310 uses a locking block 312 to insert into the locking slot 141 of the locking bracket 140, so that the air outlet port 3111 is connected to the air outlet 150. The lower mounting bracket 320 uses an arc groove 322 to cooperate with the round head 220 of the hanging nail 200, and the sealing ring 330 seals the gap between the air inlet port 3211 and the air inlet 210.
[0039] The 400-type cover is placed at the bottom of the molding cavity 110 of the two half molds 100.
[0040] The lower bracket 320 is equipped with a detachable hook 200. During the process of the lower bracket 320 driving the half mold 100 to open or close via the hook 200, the lower bracket 320 and the hook 200 may wear out. Therefore, the hook 200 can be replaced. If the lower bracket 320 is directly connected to the half mold 100, the half mold 100 will be damaged after the lower bracket 320 wears out. The damaged half mold 100 cannot cooperate with the clamp 300.
[0041] The hook 200 is equipped with a round head 220 that matches the arc groove 322 of the lower bracket 320, which increases the contact area between the round head 220 and the arc groove 322 and reduces wear between the round head 220 and the arc groove 322.
[0042] The gap between the air inlet 210 of the sealing ring 330 and the air inlet port 3211 of the air inlet channel 321 is set to prevent the cooling gas leakage of the air inlet channel 321 from affecting the cooling effect of the multiple vents 120.
[0043] The air outlet 3111 is set on the card block 312, and one end of the air outlet 150 is set in the card slot 141. When the card block 312 of the upper bracket 310 is engaged with the card slot 141 of the card holder 140, the air outlet 3111 can be directly connected to the air outlet 150, making the connection between the air outlet 3111 and the air outlet 150 more convenient.
[0044] The intake channel 321 is configured as a gentle section 3212 and an acceleration section 3213. The reduced aperture in the acceleration section 3213 accelerates the flow of cooling gas, thereby allowing the cooling gas to enter the multiple vents 120 as quickly as possible, ensuring a more uniform cooling effect in the multiple vents 120.
[0045] When producing glass bottles using two half-molds 100, the clamp 300 merges the forming cavities 110 of the two half-molds 100, so that the end cap 400 is fixed at the bottom of the two forming cavities 110. The glass bottle preform is placed in the space enclosed by the two forming cavities 110 and the top of the end cap 400. Then, the glass bottle preform is squeezed against the inner wall of the two forming cavities 110 and the top wall of the end cap 400 by gas pressurization. Cooling gas flows through the air inlet channel 321, air inlet 210, air vent 120, air outlet 150 and air outlet channel 311. The cooling gas cools the glass bottle in the forming cavity 110. After the glass bottle is formed, the clamp 300 drives the two half-molds 100 to separate so that the glass bottle can be removed.
[0046] An air vent 150 is formed in the snap-fit seat 140 at the top of the half mold 100, connecting to the top of the vent hole 120. A detachable hook 200 is provided in the connecting hole 130 at the bottom of the half mold 100. The air inlet 210 of the hook 200 connects to the bottom of the vent hole 120. After the upper hanger 310 of the clamp 300 is snapped into the snap-fit seat 140, the air outlet channel 311 connects to the air vent 150. After the lower hanger 320 of the clamp 300 is snapped into the hook 200, the air inlet channel 321 connects to the vent hole 120. The air inlet 210 allows cooling gas to flow through the air inlet channel 321, air inlet 210, vent 120, air outlet 150, and air outlet channel 311. The connection structure between the clamp 300 and the half mold 100 provides a channel for the cooling gas to flow, eliminating the need for additional channels at the top or bottom of the half mold 100. This helps reduce the height of the half mold 100 in the vertical direction, thereby reducing its weight and making the clamp 300 drive the half mold 100 to open and close more smoothly.
[0047] This utility model also provides a glass bottle forming equipment, which includes the glass bottle mold opening and closing mechanism described in the above embodiments.
[0048] Since the glass bottle forming equipment adopts all the technical solutions of the glass bottle mold opening and closing mechanism of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
