Description

Technical Field

[0001] The utility model relates to the field of automobiles, in particular to a tire molding mold. Background Art

[0002] A molding mold is a mold made in proportion to the shape and structure of an actual object. It is a tool that uses pressing or pouring to make the material into a certain shape. A tire is a component that can bear the weight of the vehicle body. A cooling structure is required during the use of the tire molding mold to increase the molding speed of the tire.

[0003] Currently, the existing tire molding molds still have some shortcomings. During the tire molding process, the cooling time is usually long and the overall efficiency is low, which leads to slow tire molding, thereby affecting the molding efficiency. At the same time, the demolding process of the tire molding mold is complicated and the demolding efficiency is low. Utility Model Content

[0004] The utility model aims to solve the problem that the tire molding mold has a long cooling time and low cooling efficiency, resulting in low molding efficiency, and a complex demoulding process and low demoulding efficiency. The utility model provides a tire molding mold, which can improve the cooling efficiency and molding efficiency, simplify the demoulding process, and thus improve the demoulding efficiency.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a tire molding mold, comprising:

[0006] roof;

[0007] A bottom plate, wherein the bottom plate and the top plate are spaced apart from each other along a first direction and connected by a plurality of support rods;

[0008] An upper template, the upper template is arranged between the bottom plate and the top plate, the upper template is connected to the top plate in a manner that it can move along the first direction, and an upper mold cavity is formed on a side of the upper template close to the bottom plate;

[0009] A lower mold cavity matched with the upper mold cavity is formed on one side of the bottom plate close to the upper mold plate, a tire mold is provided between the upper mold cavity and the lower mold cavity, and the tire mold is connected to the bottom plate in a manner that it can move along the first direction;

[0010] The upper mold plate moves downward along the first direction to close the upper mold cavity and the lower mold cavity to form an accommodating cavity, and the tire mold is accommodated in the accommodating cavity;

[0011] An annular cavity is provided on the outer side of the lower mold cavity, and the cross-section of the annular cavity is L-shaped along the first direction. A water storage cavity is provided on the bottom plate, and the water storage cavity and the lower mold cavity are spaced apart along the first direction. The annular cavity is provided between the lower mold cavity and the water storage cavity, and the water storage cavity is communicated with the annular cavity so as to supply water to the annular cavity or collect water in the annular cavity through a water pump.

[0012] By adopting the above technical scheme, the upper template is connected to the top plate in a manner that is movably along a first direction, so that when the tire needs to be molded, the upper template moves downward along the first direction to connect the upper mold cavity with the lower mold cavity, that is, the upper mold cavity and the lower mold cavity are closed to form a accommodating cavity, and the tire mold is accommodated in the accommodating cavity, that is, the accommodating cavity wraps the tire mold. At this time, the tire material is molded in the accommodating cavity, specifically on the outer surface of the tire mold. During the molding process, the water storage cavity can synchronously supply water to the annular cavity. The annular cavity is arranged on the outside of the lower mold cavity, and the tire molded in the lower mold cavity can be cooled, thereby improving the cooling efficiency and reducing the cooling time.

[0013] After the tire raw material is formed on the outer surface of the tire mold, the upper mold plate moves upward along the first direction to separate the tire mold from the upper mold cavity, and then the tire mold moves upward along the first direction with the formed tire, that is, drives the formed tire to rise and separate from the lower mold cavity, which can make it easier for workers to demold the formed tire, thereby improving the operating efficiency of the mold.

[0014] When new molding work is needed, the tire mold moves downward along the first direction and enters the lower mold cavity, and then the upper mold plate moves downward along the first direction to connect the upper mold cavity with the lower mold cavity, that is, the upper mold cavity and the lower mold cavity are closed to form a accommodating cavity, and the tire mold is accommodated in the accommodating cavity to continue the above molding work.

[0015] Along the first direction, the cross section of the annular cavity is L-shaped, so as to cool the bottom and side of the lower mold cavity at the same time, increase the cooling area, and improve the cooling efficiency. At the same time, the annular cavity is arranged on the outside of the lower mold cavity, which can reduce the internal space occupied by the lower mold cavity, and in order to ensure that the lower mold cavity matches the upper mold cavity, the tire mold can make the tire material entering the accommodating cavity directly molded into the shape of a tire without the need for secondary processing, thus saving the tire molding process.

[0016] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a tire molding mold, wherein the water pump is connected to a side of the water storage chamber close to the annular chamber, and the two ends of the water pump are respectively connected to a water outlet pipe and a water suction pipe, the water suction pipe is located in the water storage chamber, and the water outlet pipe passes through the annular chamber to connect the water storage chamber with the annular chamber.

[0017] By adopting the above technical scheme, the water in the water storage chamber is pumped from the water storage chamber through the water suction pipe and the water outlet pipe into the annular chamber, providing the annular chamber with a constant supply of new water for cooling, thereby cooling the molded tire in the lower mold cavity. At the same time, water for cooling is provided through the water storage chamber. Compared with the water used for cooling that is always in the annular cavity and continuously absorbs the heat of the lower mold cavity, this form of water can better absorb the heat generated by the tire during molding, and the cooling efficiency is higher.

[0018] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a tire molding mold, a connecting pipe is provided between the water storage cavity and the annular cavity, and the connecting pipe is spaced apart from the water outlet pipe.

[0019] By adopting the above technical scheme, a connecting pipe is provided between the water storage chamber and the annular chamber, so that the water in the annular chamber that has absorbed the heat generated by the tire during molding can flow into the water storage chamber to recycle the water and prevent a large amount of water from being wasted. At the same time, it also prevents the water that has absorbed the heat generated by the tire during molding from being reused to absorb heat, resulting in poor cooling effect, long cooling time and low efficiency.

[0020] According to another specific embodiment of the utility model, the embodiment of the utility model discloses a tire molding mold, each of the support rods is provided with a positioning plate, the positioning plates are arranged at intervals along the outer periphery of the upper template and connected to the outer periphery of the upper template, and the positioning plates are slidably connected to the support rods.

[0021] By adopting the above technical solution, the positioning plates are arranged at intervals along the outer periphery of the upper template and are connected to the outer periphery of the upper template, which can play a role in limiting the upper template. At the same time, the positioning plates are slidably connected to the support rods, so that when the upper template moves along the first direction, the positioning plates can move synchronously, that is, they can limit the upper template throughout the entire process of its movement.

When continuous operation is required, the water that has absorbed heat is discharged through the drain pipe, and new water is injected into the water storage chamber from the water injection pipe. The water changing process is simple and fast, and can be carried out simultaneously during the molding process without delaying the molding operation time, speeding up the molding time and improving the molding efficiency. If continuous operation is not required, the water that has absorbed heat can be left in the water storage chamber for storage and cooling, and used in the next operation, saving water resources.

[0030] By adopting the above technical solution, the upper template can be moved up and down along the first direction through the first driving part.

[0031] Specifically, when molding operation is required, the first driving unit drives the upper template to move downward along the first direction to close the upper mold cavity and the lower mold cavity to form a accommodating cavity. The tire mold is accommodated in the accommodating cavity, that is, the accommodating cavity wraps the tire mold. At this time, the tire material is in the accommodating cavity, specifically, it is molded on the outer surface of the tire mold. After the tire raw material is molded on the outer surface of the tire mold, the upper template moves upward along the first direction to separate the molded tire from the upper mold cavity, and then the tire mold moves upward along the first direction with the molded tire, that is, drives the molded tire to rise and separate from the lower mold cavity, completing the molding and demolding of the tire.

[0045] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] refer to Figure 1 and Figure 2The embodiment of the present application provides a tire molding mold, which can improve cooling efficiency and molding efficiency, simplify the demoulding process, and thus improve demoulding efficiency. The tire molding mold includes: a top plate 1, a bottom plate 2, an upper mold plate 3 and a tire mold 32. The bottom plate 2 and the top plate 1 are connected along a first direction (i.e. Figure 1 The top plate 1 and the bottom plate 2 are arranged at intervals (in the X direction shown in the figure) and are connected by four support rods 10. The top plate 1 is in a quadrilateral shape, the bottom plate 2 is in a quadrilateral shape, and the bottom plate 2 extends along the first direction, and the extended thickness is greater than the thickness of the top plate 1, but is not limited to this. The top plate 1 and the bottom plate 2 can be in any shape, such as a pentagon, hexagon or other shapes; the four support rods 10 extend along the first direction and are arranged at the four corners of the top plate 1 and the bottom plate 2, but are not limited to this, and the top plate 1 and the bottom plate 2 can also be arranged at other positions.

[0047] It should be noted that the embodiment of the present application does not limit the number of support rods 10, and can be selected according to the shapes of the top plate 1 and the bottom plate 2, and can also be any number, such as three, five, six, etc.

[0048] For example, reference Figure 1 and Figure 2 The upper template 3 is arranged between the bottom plate 2 and the top plate 1 . The upper template 3 is circular. The upper template 3 is connected to the top plate 1 in a movably manner along a first direction. An upper mold cavity 30 is provided on a side of the upper template 3 close to the bottom plate 2 .

[0049] For example, continue to refer to Figure 1 and Figure 2 The bottom plate 2 is provided with a lower mold cavity 21 adapted to the upper mold cavity 30 on one side thereof close to the upper mold plate 3, that is, along the first direction (i.e. Figure 2 The bottom plate 2 is provided with a lower mold cavity 21 on the top, and a tire mold 32 is provided between the upper mold cavity 30 and the lower mold cavity 21. The tire mold 32 is connected to the bottom plate 2 in a movable manner along the first direction. The upper mold plate 3 moves downward along the first direction to close the upper mold cavity 30 and the lower mold cavity 21 to form an accommodating cavity 31, and the tire mold 32 is accommodated in the accommodating cavity 31.

[0050] For example, reference Figure 2 The outer side of the lower mold cavity 21 is provided with an annular cavity 22, along the first direction (i.e. Figure 2 The cross section of the annular cavity 22 is L-shaped, so that the water in the annular cavity 22 can cool the bottom and side of the lower mold cavity at the same time, increasing the cooling area and improving the cooling efficiency. The bottom plate 2 is provided with a water storage cavity 23, and the water storage cavity 23 is connected to the lower mold cavity 21 along the first direction (i.e. Figure 2 The annular cavity 22 is arranged between the lower mold cavity 21 and the water storage cavity 23, and the water storage cavity 23 is connected to the annular cavity 22 to supply water to the annular cavity 22 or collect water in the annular cavity 22.

[0051] Exemplarily, the upper template 3 is connected to the top plate 1 in a manner that it can move along a first direction, so that when the tire needs to be molded, the upper template 3 moves downward along the first direction (i.e. Figure 2 b direction as shown) to close the upper mold cavity 30 and the lower mold cavity 21 to form a accommodating cavity 31, and the tire mold 32 is accommodated in the accommodating cavity 31, that is, the accommodating cavity 31 wraps the tire mold 32. At this time, the tire material is in the accommodating cavity 31, specifically, is molded on the outer surface of the tire mold 32. During the molding process, the water storage cavity 23 can synchronously supply water to the annular cavity 22. The annular cavity 22 is arranged on the outer side of the lower mold cavity 21, and can cool the tire molded in the lower mold cavity 21, thereby improving the cooling efficiency and reducing the cooling time.

[0052] After the tire material is formed on the outer surface of the tire mold 32, the upper mold plate 3 moves upward along the first direction (i.e. Figure 2 The tire mold 32 is separated from the upper mold cavity 30 in the direction a shown in the figure, and then the tire mold 32 moves upward along the first direction with the molded tire, that is, drives the molded tire to rise and separate from the lower mold cavity 21, which can facilitate workers to demold the molded tire, thereby improving the operation efficiency of the mold.

[0053] When a new molding operation is required, the tire mold 32 moves downward in a first direction (i.e., Figure 2 b direction as shown), enters the lower mold cavity 21, and then the upper mold plate 3 moves downward along the first direction (i.e. Figure 2 b direction as shown) to connect the upper mold cavity 30 with the lower mold cavity 21, that is, the upper mold cavity 30 and the lower mold cavity 21 are closed to form a receiving cavity 31, and the tire mold 32 is received in the receiving cavity 31, and the above molding work is continued.

[0054] At the same time, the annular cavity 22 is arranged on the outside of the lower mold cavity 21, which can reduce the internal space occupied by the lower mold cavity 21. In order to ensure that the lower mold cavity 21 matches the upper mold cavity 30, the tire mold 32 can make the tire material entering the accommodating cavity 31 be directly molded into the shape of a tire without the need for secondary processing, thus saving the tire molding process.

[0055] For example, reference Figure 1 and Figure 2 Along the first direction, the bottom plate 2 is connected to one side away from the top plate 1 with four supporting legs 20. The four supporting legs 20 are connected along the first direction (i.e. Figure 1The support legs 20 extend in the X direction as shown in the figure. Each support leg 20 includes a first support leg 201 and a second support leg 202. The first support leg 201 is cylindrical, and the second support leg 202 is trapezoidal. The support legs 20 are provided to support the base plate 2 and ensure the stability of the entire tire molding process. The four support legs 20 are arranged at intervals. Specifically, they can be arranged at the four corners of the base plate 2, but are not limited to this. Other positions of the base plate 2 can also be provided.

[0056] It should be noted that the embodiment of the present application does not limit the number of support legs 20, which can be selected according to the shape of the base plate 2, and can be any number, such as three, five, six, etc. Similarly, the embodiment of the present application does not limit the shapes of the first support leg 201 and the second support leg 202. The first support leg 201 can also be other shapes such as rectangle, square, etc., and the second support leg 202 can also be other shapes such as rectangle, square, cylinder, etc.

[0057] Exemplarily, along the first direction, the first driving part 4 is provided at the center of the side of the top plate 1 away from the bottom plate 2, but it is not limited thereto, and it may also be at a non-center. The first driving part 4 is connected to the upper template 3 to drive the upper template 3 to move downward along the first direction (i.e. Figure 2 b direction as shown in the figure) to close the upper mold cavity 30 and the lower mold cavity 21 to form a receiving cavity 31; or, drive the upper mold plate 3 to move upward along the first direction (i.e. Figure 2 The upper mold cavity 30 is moved in the direction a shown in the figure, so that the upper mold cavity 30 and the lower mold cavity 21 are separated, and the upper mold cavity 30 is separated from the tire mold 32.

[0058] Specifically, when a molding operation is required, the first driving unit 4 drives the upper mold plate 3 to move downward along a first direction (i.e. Figure 2 b direction as shown in the figure) so that the upper mold cavity 30 and the lower mold cavity 21 are closed to form a receiving cavity 31, and the tire mold 32 is received in the receiving cavity 31, that is, the receiving cavity 31 wraps the tire mold 32. At this time, the tire material is in the receiving cavity 31, specifically, on the outer surface of the tire mold 32. After the tire material is formed on the outer surface of the tire mold 32, the first driving unit 4 drives the upper mold plate 3 to move upward along the first direction (i.e. Figure 2 The tire mold 32 is separated from the upper mold cavity 30, and the tire mold 32 moves upward along the first direction (i.e., Figure 2 The molded tire is lifted up and separated from the lower mold cavity 21, thus completing the molding and demoulding of the tire.

[0059] For example, reference Figure 2 and Figure 3The first driving part 4 is a first cylinder 40, and the output shaft 41 of the first cylinder 40 passes through the top plate 1 and is fixedly connected to the upper template 3, but is not limited to this. It can also be other devices such as an electric push rod, as long as it can drive the upper template 3 to move up and down along the first direction.

[0060] For example, reference Figure 1 and Figure 2 Each support rod 10 is sleeved with a positioning plate 11, and each positioning plate 11 is similar to a triangular shape. The positioning plates 11 are arranged at intervals along the outer periphery of the upper template 3 and are connected to the outer periphery of the upper template 3. The positioning plates 11 are slidably connected to the support rods 10, so that when the upper template 3 moves along the first direction, the positioning plates 11 can move synchronously, that is, they can limit the upper template 3 during the entire movement process.

[0061] For example, reference Figure 2 and Figure 3 Along the first direction, a side of the tire mold 32 away from the top plate 1 is connected to a second driving unit 5, and the second driving unit 5 is arranged on the bottom plate 2 and connected to the tire mold 32, and is used to drive the tire mold 32 to move up and down along the first direction.

[0062] Specifically, when a new molding operation is required, the second driving unit 5 drives the tire mold 32 to move downward in the first direction (i.e. Figure 2 b direction as shown), enters the lower mold cavity 21, and then the upper mold plate 3 moves downward along the first direction (i.e. Figure 2 b direction as shown), so that the upper mold cavity 30 is connected with the lower mold cavity 21, that is, the upper mold cavity 30 and the lower mold cavity 21 are closed to form an accommodating cavity 31, and the tire mold 32 is accommodated in the accommodating cavity 31 to perform the above-mentioned molding work.

[0063] After the tire material is formed on the outer surface of the tire mold 32, the second driving unit 5 drives the tire mold 32 to move upward along the first direction (i.e. Figure 2 The molded tire is lifted up and separated from the lower mold cavity 21, which can facilitate workers to demold the molded tire, thereby improving the mold operation efficiency.

[0064] Exemplarily, the second driving part 5 is a second cylinder 50, and the output shaft of the second cylinder 50 is fixedly connected to the bottom of the tire mold 32, but is not limited to this. It can also be other devices such as an electric push rod, as long as it can drive the tire mold 32 to move up and down along the first direction.

[0065] Exemplarily, a water pump 24 is connected to a side of the water storage chamber 23 close to the annular chamber 22. Specifically, the water storage chamber 23 is connected to a water pump 24 along a first direction (i.e. Figure 3A water pump 24 is fixed to the top inner wall of the water storage chamber 23, and both ends of the water pump 24 are respectively connected to a water outlet pipe 26 and a water suction pipe 25, the water suction pipe 25 is located in the water storage chamber 23, and the water outlet pipe 26 passes through the annular cavity 22, so that the water storage chamber 23 and the annular cavity 22 are connected; a connecting pipe 27 is provided between the water storage chamber 23 and the annular cavity 22, and the connecting pipe 27 and the water outlet pipe 26 are arranged at intervals.

[0066] Illustratively, water in the water storage chamber 23 is pumped from the water storage chamber 23 via the water suction pipe 25 and the water outlet pipe 26 into the annular chamber 22, providing the annular chamber 22 with a continuous new source of water for cooling, thereby cooling the molded tire in the lower mold cavity 21. At the same time, the water for cooling is provided through the water storage chamber 23. Compared with the water for cooling being always in the annular chamber 22 and constantly absorbing the heat of the lower mold cavity 21, it can absorb more heat generated by the tire during molding, and the cooling efficiency is higher.

[0067] Illustratively, a connecting pipe is provided between the water storage chamber 23 and the annular chamber 22 so that the water in the annular chamber 22 that has absorbed the heat generated during tire molding can flow into the water storage chamber 23 to recycle the water and prevent a large amount of water from being wasted. This also prevents the water that has absorbed the heat generated during tire molding from being reused to absorb heat, resulting in poor cooling effect, long cooling time and low efficiency.

[0068] For example, reference Figure 1 and Figure 2 An injection hole 33 is provided on a side of the upper mold plate 3 away from the bottom plate 2, and the injection hole 33 is connected with the upper mold cavity 30, so that the tire material can be injected into the upper mold cavity 30 and the lower mold cavity 21 through the injection hole 33, that is, injected into the accommodating cavity 31, that is, the outer surface of the tire mold 32, so that the tire material is molded on the outer surface of the tire mold 32.

[0069] For example, reference Figure 2 and Figure 3 A water injection pipe 28 and a drainage pipe 29 are embedded and fixed on the surface of the bottom plate 2. The water injection pipe 28 and the drainage pipe 29 are both connected to the water storage chamber 23, and can play the effect of injecting water into and discharging water from the water storage chamber 23.

[0070] Specifically, when the tire molding mold is in use, water is always stored in the water storage chamber 23. After the molding of a tire is completed, the water that has absorbed heat enters the water storage chamber 23 from the annular cavity 22 through the connecting pipe 27. When continuous operation is required, the water that has absorbed heat is discharged through the drain pipe 29, and new water is injected into the water storage chamber 23 from the water injection pipe 28. The water replacement process is simple and fast, and can be carried out simultaneously during the molding process without delaying the molding operation time, speeding up the molding time and improving the molding efficiency. If continuous operation is not required, the water that has absorbed heat can be left in the water storage chamber 23 for storage and cooling, and will be used in the next operation, saving water resources.
