Description

Technical Field

[0001] This invention relates to the field of glass product processing mold technology, specifically a shape control mold for glass products processed by small-mouth blow molding. Background Technology

[0002] Glass products are made primarily from glass and are used in various fields. Glass is a relatively transparent solid substance that forms a continuous network structure when molten. During cooling, its viscosity gradually increases and it hardens without crystallizing. It is a silicate-based non-metallic material. The prototype of a glass product is first formed by pressing. Compressed air can be used to blow glass paste into finished products using the pressure blowing method. The press blowing machine used to produce glass bottles is a commonly used type of pressure blowing machine, characterized by its fast forming speed, high production efficiency, and good product quality.

[0003] Patent document CN113845293A discloses a glass bottle blowing molding system. When starting to blow glass bottles, the blowpipe and raw material are placed between two molds. The first drive motor is activated, and the first drive shaft at the motor's output rotates, driving a belt. Two spur gears on the belt simultaneously begin to rotate. The rotation of the spur gears drives two rotating shafts, which in turn rotate the two drive gears. These drive gears engage with gears below the turntable for transmission. The turntable rotates within a clamping cavity. A sliding groove above the turntable allows the two molds to gradually move closer together until they are perfectly fitted. Once the heating element in the center is heated, the normal blowing process can begin. The two molds, relying on the sliding groove of the turntable, can fit tightly together, and the heating groove in the center of the mold allows for better shaping of the glass bottle during the blowing process.

[0004] However, in the process of implementing the above technical solution, the following technical problems were found:

[0005] Existing glass bottles made using the pressure blow molding method require the droplet to first enter the primary mold. When the neck is shaped on the droplet, a downward blowing method is used to make the inside of the droplet hollow. Finally, the finished product is blown inside the bottle mold. This process requires the use of the primary mold and the bottle mold, and demolding is required in the middle to transfer the forced bottle inside the primary mold, which is not conducive to improving production efficiency. Summary of the Invention

[0006] To overcome the shortcomings of existing glass bottle manufacturing processes using the pressure blow molding method, which require the use of a preliminary mold and a bottle mold, and the need for demolding and transferring the forced bottle inside the preliminary mold, thus hindering production efficiency, this application provides a glass product shape control mold for small-mouth pressure blow molding. By enabling the hydraulic push rod to rotate synchronously under the support of a connecting seat, a support bearing, and a support seat, it is easy to control the flipping of the glass products within the two mold bodies. After the material droplet is blown from the bottom to the top to form a hollow cavity, it can be directly transferred to the blown product process without the need for mold opening and transfer, which is beneficial to improving production efficiency.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A shape control mold for glass products processed by small-mouth blow molding includes a mold body, a rotating component, and a flipping component, wherein there are two mold bodies;

[0009] The rotating components are located on both sides of the two mold bodies;

[0010] The flipping component is located on one side of the two mold bodies, and at the top and bottom of one end of the rotating component;

[0011] The rotating assembly includes a second rotating hydraulic cylinder. One end of the rotating shaft of the second rotating hydraulic cylinder is pin-connected to a connecting shaft. One end of the connecting shaft is assembled to one side of a mold body. A hydraulic push rod is assembled to one side of the other mold body. The hydraulic push rod controls one mold body to engage with the other mold body. The second rotating hydraulic cylinder controls one mold body to rotate the other mold body by means of the hydraulic push rod.

[0012] In one possible implementation, mold supports are provided on the outer sides of the two mold bodies, one side of the second rotating hydraulic cylinder is assembled to the outer wall of one side of the mold support, and the hydraulic push rod is movably connected to the inside of the other side of the mold support.

[0013] In one possible implementation, a bearing seat is assembled to the inner wall of one side of the mold support, the shaft of the second rotating hydraulic cylinder is movably connected to the inside of the mold support, and one end of the connecting shaft is interference-fitted into the inside of the bearing seat.

[0014] In one possible implementation, a mounting slot is machined on the top of one side of the mold support, a limiting groove is machined on the inner wall of the mounting slot, a support seat is plugged into the limiting groove, a support bearing is interference-fitted inside the support seat, a connecting seat is provided on the inner side of the support bearing, and the movable end of the hydraulic push rod passes through the interior of the connecting seat.

[0015] In one possible implementation, the connecting seat includes an adapter sleeve, one end of which is integrally formed with a support plate. The adapter sleeve is interference-fitted to the inner side of the support bearing. One end of the adapter sleeve is machined with a ring track. After passing through the inner side of the support seat, a retaining ring is assembled inside the ring track to prevent the support seat and the connecting seat from separating and to ensure that the support seat and the connecting seat are set independently. The fixed end of the hydraulic push rod is assembled to the support plate.

[0016] In one possible implementation, the cross-section of the support disk is an isosceles trapezoid, such that the outer edge of one side of the support disk is separated from the outer surface of the support bearing.

[0017] In one possible implementation, a stop is provided at the top of the mounting slot, and the stop is plugged into the inside of the limiting slot so that the inner side of its bottom fits against the surface of the support base.

[0018] In one possible implementation, positioning strips are formed on one side of the surfaces of both mold bodies, and positioning grooves are machined on the other side of the surfaces of both mold bodies. The positioning strip on one mold body is adapted to and connected to the positioning groove on the other mold body.

[0019] In one possible implementation, the flipping assembly includes two first rotating hydraulic cylinders, one end of each of the two first rotating hydraulic cylinder shafts is assembled with a blocking member, and the top and bottom of one side of the mold support are machined with a stand, and the first rotating hydraulic cylinder is assembled with one end of the stand.

[0020] In one possible implementation, the blocking element is divided into a stop and a mold base. The surface of the mold base is machined with shaped protrusions. One of the first rotary hydraulic cylinders controls the mold base to flip, blocking the bottom of the two upright mold bodies and causing the shaped protrusions to extend into the inside of the two mold bodies. Another of the first rotary hydraulic cylinders controls the stop to flip, blocking the top of the two inverted mold bodies.

[0021] The beneficial effects of this application are as follows:

[0022] First, in this solution, by making the hydraulic push rod rotate synchronously under the support of the connecting seat, the support bearing and the support seat, it is easy to control the flipping of the glass products in the two mold bodies. After the material droplet is blown from the bottom to the top to form a hollow cavity, it can be directly transferred to the blown product process without the need for mold opening and transfer work, which is conducive to improving production efficiency.

[0023] Secondly, in this solution, by assembling and connecting the support plate on the connecting seat with the fixed end of the hydraulic push rod, and after the adapter sleeve on the connecting seat is pinned to the inside of the support bearing and passes through the inside of the support seat, a retaining ring is installed in the annular channel at one end of the adapter sleeve. This allows the support seat and the connecting seat to be independent and restricts the connection seat from disengaging from the support seat, which helps to ensure that the hydraulic push rod rotates smoothly under the support of the support bearing.

[0024] Thirdly, in this solution, a first rotating hydraulic cylinder is used to control the rotation of the stop seat, which seals the top of the two inverted mold bodies. This allows the gas from the bottom to the top to preform the glass material into glass products. Another first rotating hydraulic cylinder is used to control the rotation of the mold seat, which seals the bottom of the two upright mold bodies and allows the forming protrusion to extend into the inside of the two mold bodies. This provides shaping support for the preformed glass products to be press-blown into finished products. This solution can adapt to both upright and inverted mold bodies for processing glass products, and is simple and convenient. Attached Figure Description

[0033] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0034] Example 1:

[0035] This embodiment describes the specific structure of a shape control mold for glass products processed by the small-mouth blow molding method. See details below. Figures 1-7 As shown, it includes two mold bodies 6, a rotating assembly 3 disposed on both sides of the two mold bodies 6, and a flipping assembly 1 disposed on one side of the two mold bodies 6 and located at the top and bottom of one end of the rotating assembly 3. The rotating assembly 3 includes a second rotating hydraulic cylinder 301. One end of the rotating shaft of the second rotating hydraulic cylinder 301 is pin-connected to a connecting shaft 303. One end of the connecting shaft 303 is assembled to one side of one mold body 6, and a hydraulic push rod 302 is assembled to one side of the other mold body 6.

[0036] The two mold bodies 6 have positioning strips 8 formed on one side of their surfaces and positioning grooves 9 processed on the other side of their surfaces. Since the positioning strips 8 on one mold body 6 are adapted to and connected to the positioning grooves 9 on the other mold body 6, when the hydraulic push rod 302 controls one mold body 6 to engage with the other mold body 6, an inner cavity for press blow molding of glass products can be formed between the two mold bodies 6.

[0037] At the same time, by driving the connecting shaft 303 to control one mold body 6 to rotate the other mold body 6, the glass products in the two mold bodies 6 can be controlled to rotate. After the material droplet is blown from the bottom to the top to form a hollow cavity, it can be directly converted to the blown product process.

[0038] like Figure 1 As shown, mold supports 5 are provided on the outer side of the two mold bodies 6. One side of the second rotating hydraulic cylinder 301 is assembled and connected to the outer wall of one side of the mold support 5, and the hydraulic push rod 302 is movably connected to the inside of the other side of the mold support 5.

[0039] In order to ensure the connection effect between the mold body 6 and the connecting shaft 303 and the second rotating hydraulic cylinder 301, such as Figure 1 , Figure 4 and Figure 6 As shown, a bearing seat 2 is assembled and connected to the inner wall of one side of the mold support 5. The shaft of the second rotating hydraulic cylinder 301 is movably connected to the inside of the mold support 5, and one end of the connecting shaft 303 is interference-fitted inside the bearing seat 2. The connecting shaft 303 can be supported by the fixed bearing seat 2, so that one mold body 6 drives the other mold body 6 to be set vertically.

[0040] Secondly, in order for the hydraulic push rod 302 connected to one mold body 6 to rotate with both mold bodies 6, such as Figure 2 , Figure 5 and Figure 6 As shown, a mounting slot 7 is machined on the top of one side of the mold support 5. A limiting groove 14 is machined on the inner wall of the mounting slot 7. A support seat 11 is plugged into the limiting groove 14. A support bearing 12 is interference-fitted inside the support seat 11. A connecting seat 13 is provided on the inner side of the support bearing 12. By allowing the movable end of the hydraulic push rod 302 to pass through the interior of the connecting seat 13, the support seat 11, the support bearing 12, and the connecting seat 13 can provide support for the hydraulic push rod 302 to control the movement of a mold body 6.

[0041] Furthermore, to prevent the hydraulic push rod 302 from wobbling as it rotates with the two mold bodies 6, such as... Figure 6 As shown, a stop 15 is provided at the top of the mounting slot 7. By inserting the stop 15 into the inside of the limiting slot 14, and after the inner side of its bottom is in contact with the surface of the support base 11, the swaying of the support base 11 inside the limiting slot 14 can be restricted.

[0042] By adopting the above technical solution:

[0043] The above design connects a second rotating hydraulic cylinder 301 to one side of a mold body 6 via a connecting shaft 303, and a hydraulic push rod 302 to one side of another mold body 6. The second rotating hydraulic cylinder 301 is mounted on the outer wall of the mold support 5, so that the connecting shaft 303 drives the mold body 6 to rotate under the support of the bearing seat 2. The hydraulic push rod 302 is connected to the support bearing 12 via a connecting seat 13, and is installed inside one side of the mold support 5 with the support seat 11 as support.

[0044] When the hydraulic push rod 302 controls one mold body 6 to move closer to another mold body 6, the two mold bodies 6 are connected and fixed by means of the positioning strip 8 and the positioning groove 9. The second rotating hydraulic cylinder 301 drives the connecting shaft 303 to control one mold body 6 to rotate the other mold body 6. The hydraulic push rod 302 can rotate synchronously under the support of the connecting seat 13, the support bearing 12 and the support seat 11, which facilitates the control of the glass products in the two mold bodies 6 to rotate. After the material droplet is blown from the bottom to the top to form a hollow cavity, it can be directly transferred to the blown product process without the need for mold opening and transfer work, which is conducive to improving production efficiency.

[0045] Example 2:

[0046] Based on Embodiment 1, this embodiment describes the specific structure of the connecting seat 13. The connecting seat 13 includes an adapter sleeve 1301. One end of the adapter sleeve 1301 is integrally formed with a support disk 1302, and one end of the adapter sleeve 1301 is machined with an annular channel.

[0047] The fixed end of the hydraulic push rod 302 is assembled with the support plate 1302 and the adapter sleeve 1301 is interference-fitted on the inner side of the support bearing 12. After the adapter sleeve 1301 passes through the inner side of the support seat 11, a retaining ring can be assembled inside the ring to restrict the support seat 11 and the connecting seat 13 from disengaging and to ensure that the support seat 11 and the connecting seat 13 are set independently. This makes it easy for the hydraulic push rod 302 to control the movement of a mold body 6 and rotate with the mold body 6 connected to it.

[0048] Secondly, to ensure the connection between the support plate 1302 and the fixed end of the hydraulic push rod 302, during the subsequent operation of the hydraulic push rod 302, the relative rotation of the inner and outer sides of the support bearing 12 will be affected, such as... Figure 7 As shown, the cross-section of the support disk 1302 is an isosceles trapezoid. By leaving a gap between the outer surface of the support disk 1302 and the outer surface of the support bearing 12, the outer edge of one side of the support disk 1302 can be separated from the outer surface of the support bearing 12.

[0049] By adopting the above technical solution:

[0050] The above design sets the connecting seat 13 in the form of a transition sleeve 1301 and a support plate 1302, so that the support plate 1302 is assembled and connected to the fixed end of the hydraulic push rod 302. After the transition sleeve 1301 is pinned to the inside of the support bearing 12 and passes through the inside of the support seat 11, a retaining ring is installed in the annular channel at one end of the transition sleeve 1301. This can ensure that the support seat 11 and the connecting seat 13 are independent and prevent the connecting seat 13 from disengaging from the support seat 11. This is beneficial to ensure that the hydraulic push rod 302 rotates smoothly under the support of the support bearing 12.

[0051] Meanwhile, after the adapter sleeve 1301 is pinned to the inside of the support bearing 12 and passes through the inside of the support seat 11, because the cross section of the support plate 1302 is an isosceles trapezoid, a gap can be left between the outer surface of the support plate 1302 and the outer surface of the support bearing 12, so as to avoid the support plate 1302 being connected to the fixed end of the hydraulic push rod 302, which would affect the relative rotation of the inner and outer sides of the support bearing 12 during the subsequent operation of the hydraulic push rod 302.

[0052] Example 3:

[0053] Based on Example 1, this example describes the specific structure of the flipping component 1, such as... Figures 1 to 4 As shown, the flipping assembly 1 includes two first rotating hydraulic cylinders 102. One end of the rotating shaft of each of the two first rotating hydraulic cylinders 102 is connected to a blocking member 101. The top and bottom of one side of the mold support 5 are both machined with a stand 4.

[0054] The first rotating hydraulic cylinder 102 is assembled and connected to one end of the upright frame 4, while the blocking component 101 is divided into a stop seat 1012 and a mold seat 1011. The surface of the mold seat 1011 is machined with forming protrusions 10. When the first rotating hydraulic cylinder 102 controls the stop seat 1012 to flip and seal the top of the two inverted mold bodies 6, the air blowing structure in the prior art can blow air from the bottom to the top to preform the glass droplets into glass products.

[0055] At the same time, when a first rotating hydraulic cylinder 102 controls the mold base 1011 to flip, the bottom of the two upright mold bodies 6 can be sealed, and the forming protrusion 10 can be inserted into the inner side of the two mold bodies 6, thereby providing shaping support for the pre-formed glass products to be blown into finished products.

[0056] By adopting the above technical solution:

[0057] The above design utilizes two first rotating hydraulic cylinders 102 to control the mold base 1011 and the stop 1012 to flip. When one first rotating hydraulic cylinder 102 controls the stop 1012 to flip, the top of the two inverted mold bodies 6 is sealed, allowing the gas from the bottom to the top to preform the glass droplets into glass products. When the other first rotating hydraulic cylinder 102 controls the mold base 1011 to flip, the bottom of the two upright mold bodies 6 is sealed, and the forming protrusion 10 extends into the inner side of the two mold bodies 6, thereby providing shaping support for the preformed glass products to be blown into finished products, so as to adapt to the glass product processing work of the two upright and inverted mold bodies 6.

[0058] Specifically, when using this glass product shape control mold for small-mouth blow molding to produce glass products:

[0059] First, molten glass droplets are fed between the two mold bodies 6, causing the hydraulic push rod 302 to control one mold body 6 to move closer to the other mold body 6. The two mold bodies 6 are then connected and fixed by means of the positioning strip 8 and the positioning groove 9.

[0060] Then, the first rotating hydraulic cylinder 102 at the top is activated, which controls the stop 1012 to flip, and after the top of the two inverted mold bodies 6 is sealed, the gas from the bottom to the top will preform the glass material into glass products.

[0061] Furthermore, the second rotating hydraulic cylinder 301 drives the connecting shaft 303 to control one mold body 6 to rotate the other mold body 6, so that the hydraulic push rod 302 can rotate synchronously under the support of the connecting seat 13, the support bearing 12 and the support seat 11, thereby controlling the glass products inside the two mold bodies 6 to rotate.

[0062] Finally, the first rotating hydraulic cylinder 102 located at the bottom controls the mold base 1011 to flip over, sealing the bottom of the two upright mold bodies 6, and causing the forming protrusion 10 to extend into the inside of the two mold bodies 6, thereby providing support at the bottom of the pre-formed glass product, so that the gas delivered from the top to the bottom can press-blow the pre-formed glass product into the finished product.

[0063] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
