[0001] The present invention relates to the field of glass bottle production molds, and particularly to a glass bottle production mold facilitating the replacement of a mouth mold. Background Art

[0002] During the production of glass bottles, the mouth mold and the core are very important components, which cooperate with each other to form the bottle mouth and the internal shape of the glass bottle respectively.

[0003] However, in existing equipment, to facilitate demolding, the mouth mold is divided into two halves, and the core also needs to be controlled separately. Therefore, the originally cooperating components are divided into three parts, and three manipulators are required to drive the mouth mold and the core to move respectively: first drive the mouth mold to close the mold, and then accurately insert the core into the glass blank.

[0004] This complex design makes the glass bottle production equipment rely on more mechanical equipment, pneumatic pipe fittings and sensors to ensure the accurate alignment and mold closing and blow molding of the mouth mold and the core. As a result, not only the production cost increases, but the maintenance cost also rises accordingly. Summary of the Invention

[0005] In order to overcome the defect that in the existing glass bottle production mold, the mutually cooperating mouth mold and core are used as three parts, resulting in the need for more mechanical equipment, pneumatic pipe fittings and sensors to drive the mouth mold and the core to perform accurate alignment and then complete mold closing and blow molding during the production of glass bottles, with high production and maintenance costs, the present invention provides a glass bottle production mold facilitating the replacement of a mouth mold.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0028] A glass bottle production mold facilitating the replacement of the mouth mold, as Figures 1-6 shown, includes a mouth mold body; the mouth mold body is composed of a mouth module one 1 and a mouth module two 2;

[0029] It further includes a die core 3, a connecting block 101, a limiting block 12 and a mold closing assembly; the connecting block 101 is composed of a first merging block 10101 and a second merging block 10102, and the first merging block 10101 and the second merging block 10102 are connected by bolts; a die core 3 is connected to the middle of the connecting block 101; a thread is provided in the middle of the die core 3, and the die core 3 is threadedly connected to the connecting block 101; two symmetrically arranged front and rear limiting blocks 12 are fixedly connected to both the mouth module one 1 and the mouth module two 2; two symmetrically arranged front and rear through grooves 1201 are opened on both the first merging block 10101 and the second merging block 10102; a limiting sliding groove 1202 is opened in each through groove 1201; each limiting block 12 slides in the corresponding limiting sliding groove 1202; a mold closing assembly for driving the mouth module one 1 and the mouth module two 2 to close the mold is connected inside the connecting block 101; threads with the same pitch are provided on the upper sides of both the die core 3 and the connecting block 101; a film blowing port 3001 is opened inside the die core 3.

[0030] The mold clamping assembly includes a clamping block 11, a fixed block 104, a sliding block 105, a first air pipe 106 and a second air pipe 107; the first air pipe 106 and the second air pipe 107 are fixedly connected inside the first merging block 10101; two symmetrically arranged fixed blocks 104 are fixedly connected between the first merging block 10101 and the second merging block 10102; a sliding block 105 is slidably connected inside each fixed block 104; a sealing part 10501 is arranged on each sliding block 105; a clamping groove 10502 is formed on the lower side of each sliding block 105; clamping blocks 11 are fixedly connected to both the mouth module one 1 and the mouth module two 2; each clamping block 11 is clamped inside the corresponding clamping groove 10502; a first air inlet 10601 and a second air inlet 10701 are arranged inside each fixed block 104; the first air inlet 10601 is communicated with the first air pipe 106; the second air inlet 10701 is communicated with the second air pipe 107.

[0031] The surface of the mold core 3 is provided with a chromium plating layer, which has good heat resistance, a smooth surface, is convenient for demolding, has good corrosion resistance, and a long service life.

[0032] A disassembly port 3002 is arranged on the lower side of the film blowing port 3001. The disassembly port 3002 is in the shape of an internal hexagon, which is convenient for workers to use an internal hexagon wrench to disassemble and replace the mold core 3, avoiding the damage of the chromium plating layer on the surface of the mold core 3 caused by the workers directly clamping the surface of the mold core 3 and rotating the mold core 3 for removal.

[0033] Both the first air pipe 106 and the second air pipe 107 are made of silicone rubber material, which has good heat resistance and aging resistance, and a long service life.

[0034] The working principle of the above embodiment is as follows:

[0035] First, as shown in Figure 5 and Figure 6 , the worker inserts the clamping blocks 11 on the mouth module one 1 and the mouth module two 2 into the corresponding clamping grooves 10502, and then connects the mouth module one 1 and the mouth module two 2 with the corresponding sliding blocks 105, and further connects them with the corresponding fixed blocks 104;

[0036] Then, as shown in Figure 3As shown: The worker then combines the first merging block 10101 and the second merging block 10102 with the fixing block 104. At this time, first align the through groove 1201 with the limiting block 12, then place the first merging block 10101 and the second merging block 10102 on the upper sides of the mouth module one 1 and the mouth module two 2, so that the limiting block 12 enters the through groove 1201. Then, press and combine the first merging block 10101 and the second merging block 10102 towards the opposite sides, and fix the first merging block 10101 and the second merging block 10102 with bolts. At this time, the limiting block 12 will enter the corresponding limiting sliding groove 1202 and be limited by the limiting sliding groove 1202. Thus, the mouth module one 1 and the mouth module two 2 are combined and connected with the first merging block 10101 and the second merging block 10102, and the fixing block 104 will also be clamped into the connecting block 101 composed of the corresponding first merging block 10101 and the second merging block 10102. And at this time, the first air inlet 10601 is communicated with the first air pipe 106; the second air inlet 10701 is communicated with the second air pipe 107. Then, the worker screws the die core 3 together with the connecting block 101 by means of the thread provided in the middle. Thus, the mouth module one 1, the mouth module two 2 and the die core 3 are connected together through the connecting block 101. Then, the worker screws and fixes the die core 3 and the connecting block 101 together on the manipulator by means of the threads with the same pitch provided on the upper sides of the die core 3 and the connecting block 101. At this time, the die core 3 will be connected to the film blowing mechanism. Then, the worker connects the first air pipe 106 and the second air pipe 107 to an external air pump;

[0037] During the mold closing and blow molding operations, the worker only needs to control a manipulator to drive the connecting block 101 to move, thereby driving the first mouth module 1, the second mouth module 2, and the mold core 3 to move directly above the bottle mouth of the corresponding glass blank. Then, drive the connecting block 101 to move straight down to insert the mold core 3 into the glass blank. It should be noted here that in the initial state, the first mouth module 1 and the second mouth module 2 are in a separated state. Then, start the external air pump to inject gas into the first air pipe 106. Then, the gas will enter the fixed block 104 through the first air inlet 10601 and squeeze the sliding block 105 towards the mold core 3. Then, the two sliding blocks 105 will drive the first mouth module 1 and the second mouth module 2 to move towards each other and complete the mold closing. After the mold closing, blow molding is performed through the mold core 3, and the gas enters the glass blank through the blow molding port 3001 for blow molding. After the glass bottle is blow molded, the external air pump stops injecting gas into the first air pipe 106, and then injects gas into the second air pipe 107. At this time, the gas will enter the fixed block 104 through the second air inlet 10701 and squeeze the sliding block 105 in the direction away from the mold core 3. Then, the two sliding blocks 105 will drive the first mouth module 1 and the second mouth module 2 to move away from each other and complete the demolding. Then, the mold core 3 is pulled out of the glass blank by the manipulator. Thus, the first mouth module 1, the second mouth module 2, and the mold core 3 are connected into a whole. Thus, using one manipulator can complete the complex mold closing and blow molding operations in the prior art, greatly reducing the mechanical equipment, pneumatic pipe fittings, and sensors required for the glass bottle production equipment, and greatly reducing the production and maintenance costs;

[0038] Furthermore, since the mold core 3 and the upper side of the connecting block 101 are both provided with threads having the same pitch, when installing and disassembling the connecting block 101 and the mold core 3, only need to align the connection ports of the mold core 3 and the connecting block 101 with the manipulator and then rotate the outer connecting block 101 to complete the installation and disassembly of the mold core 3 and the connecting block 101, thereby completing the overall installation and disassembly of the first mouth module 1, the second mouth module 2, and the mold core 3, which is convenient to use;

[0039] Furthermore, since the first merging block 10101 and the second merging block 10102 are connected by bolts and the mold core 3 is threadedly connected to the connecting block 101, when it is necessary to replace the first mouth module 1, the second mouth module 2, and the mold core 3, they can also be easily disassembled for separate replacement and cleaning, which has strong practicability.

[0040] On the basis of the above technical effects, the present invention also has the following advantages:

[0041] The surface of the mold core 3 is provided with a chromium plating layer, which has good heat resistance, a smooth surface, is convenient for demolding, and has good corrosion resistance, and a long service life;

[0042] The disassembly port 3002 is in the shape of an internal hexagon, which is convenient for workers to use an internal hexagon wrench to disassemble and replace the die core 3, avoiding the damage of the chrome coating on the surface of the die core 3 caused by the worker directly clamping the surface of the die core 3 and rotating the die core 3 for removal.

[0043] Both the first air pipe 106 and the second air pipe 107 are made of silicone rubber, with good heat resistance and aging resistance, and long service life. Embodiment 2

[0044] Based on Embodiment 1, as Figure 4 shown, it further includes a plugging block 13; two air outlets 3003 are provided in the middle of the die core 3; the air outlets 3003 are communicated with the film blowing port 3001; cooling ports 1301 are provided on the lower sides of the first merging block 10101 and the second merging block 10102; plugging blocks 13 are fixedly connected to both the die head module 1 and the die head module 2, and in the mold closing state, the plugging blocks 13 block the cooling ports 1301.

[0045] A sealing ring is provided on the plugging block 13, and the sealing ring is made of silicone rubber.

[0046] The cooling port 1301 is in a flared shape.

[0047] It further includes a flow splitting block 103; a flow splitting block 103 is fixedly connected to the communication part between the air outlet 3003 and the film blowing port 3001; the flow splitting block 103 is in a frustum shape, and a ventilation groove is provided in the middle.

[0048] Two drainage grooves 10301 are provided on the outer side of the flow splitting block 103.

[0049] The working principle of the above embodiment is as follows:

[0050] After the glass bottle blow molding described in Embodiment 1, some high-performance metallic glass molds are difficult to withstand frequent use in high-temperature and high-pressure environments during use. Therefore, it is necessary to cool the mold with cold air. However, the prior art requires an additional cooling device to cool the formed glass mold and the glass bottle, and a cooling water channel is also required in the die head, which is rather troublesome and greatly increases the cooling cost.

[0051] Therefore, in the initial state, as shown in the die head module 1 in Figure 4 : in the mold closing state, the cooling port 1301 is blocked by the plugging block 13. At this time, the gas at the film blowing port 3001 will not blow out from the cooling port 1301, thus ensuring the film blowing forming effect; when the die head module 1 and the die head module 2 are separated and demolded, as in Figure 4As shown in the mouth module two 2 in [reference], the plugging block 13 will move away from the mold core 3 along with the mouth module one 1 and the mouth module two 2, thereby releasing the plugging of the cooling port 1301 by the plugging block 13. At this time, part of the air flow at the film blowing port 3001 will enter the air outlet 3003 and be blown out from the cooling port 1301 to cool the outer surface of the formed glass bottle, and the other air flow continues to be blown out from the film blowing port 3001 to cool the inner surface of the glass bottle; the cooling speed is increased, the production efficiency is improved, and the cooling port 1301 is in a trumpet shape; after the air flow flows out, it will also be blown out in all directions, thereby cooling the mouth module one 1 and the mouth module two 2;

[0052] Furthermore, when the air flow is blown out from the film blowing port 3001, since the air outlet 3003 is not along the air flow channel, most of the air flow will be blown out from the film blowing port 3001; the air flow blown out from the air outlet 3003 is less, so the frustum-shaped flow dividing block 103 is used to guide the air flow, so that more air flow can also be blown out from the air outlet 3003, ensuring the cooling effect of the outer surface of the glass bottle, the mouth module one 1 and the mouth module two 2;

[0053] However, after the flow dividing block 103 is set, the cooling port 1301 is in a plugged state during mold closing and blow molding; but the flow dividing block 103 will guide a large amount of air flow to the air outlet 3003, resulting in a large air flow blowing at the cooling port 1301, and then causing the plugging block 13 to be subjected to a large air flow impact, which in turn affects the mold closing state of the mouth module one 1 and the mouth module two 2. Therefore, a drainage groove 10301 is provided on the outer side of the flow dividing block 103. When the cooling port 1301 is plugged in the mold closing state, the air flow guided by the flow dividing block 103 can re-enter the film blowing port 3001 through the drainage groove 10301 for film blowing operation, avoiding the plugging block 13 from being subjected to a large air flow impact and thus affecting the mold closing state of the mouth module one 1 and the mouth module two 2.

[0054] On the basis of the above technical effects, the present invention also has the following advantages:

[0055] A sealing ring is provided on the plugging block 13 to ensure the sealing effect of the plugging block 13 on the cooling port 1301, and the sealing ring is made of silicone rubber, which has good heat resistance and aging resistance and a long service life.

Therefore, the scope of the present disclosure should not be limited to the above embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
