Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, and in particular to a turntable base and a turntable device. Background Technology

[0002] In traditional injection molding shoe manufacturing equipment, to accelerate the sole molding process, circulating cooling water is typically supplied to the left and right shoe molds to cool the molded shoe. This cooling method introduces cooling water into the shoe mold and uses heat conduction to carry away the heat from the sole, accelerating the temperature reduction and thus improving the molding efficiency. However, due to the relatively small thickness of the sole, the contact area between the left and right shoe molds and the sole to be molded is limited, so the effect of accelerating cooling is limited, and the improvement in sole molding efficiency is not significant.

[0003] To further optimize cooling, subsequent technical improvements employed a bottom cooling plate. Compared to the side surface of the sole, the bottom area of ​​the sole is larger. Therefore, by placing a cooling plate under the bottom mold of the shoe mold, the bottom mold is cooled, maintaining its temperature at a level sufficient to effectively cool the sole, thus completing the cooling and molding process. Correspondingly, indirectly cooling the sole during molding significantly improves cooling efficiency, thereby increasing molding efficiency. This improvement involves directly mounting the bottom cooling plate onto the existing turntable base, ensuring it fits snugly against the bottom mold, reducing modification costs. However, this modification introduces a new problem: the increased height of the shoe mold due to the bottom cooling plate increases the operator's working height, affecting ease of operation.

[0004] Furthermore, shoe molds typically employ a left-right opening design. To ensure that the left and right shoe molds do not interfere with the bottom cooling plate during rotation, shims need to be added to the bottom of the shoe mold handle during modification. These shims are fitted onto the support rod connecting the turntable base and the turntable top, moving the shoe mold handle away from the bottom fixing point of the support rod. While this design solves the interference problem, it reduces the overall structural stability, thus affecting the mold clamping accuracy. Decreased mold clamping accuracy can lead to dimensional deviations or surface defects during sole molding, affecting product quality. Additionally, the shims and cooling plate, positioned on the surface of the turntable base, can cause interference with the movement of external sole mold components and affect the installation of other components that need to be mounted on the turntable base. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a turntable base and a turntable device, which can solve the problem that the addition of a cooling plate requires the installation of a shim to raise the shoe mold handle and the left and right shoe molds to prevent interference between the left and right shoe molds and the cooling plate.

The groove of the first pipe groove near the end of the cooling plate corresponds to the water inlet of the cooling plate, so that the external water outlet pipe near the cooling plate can be embedded in the first pipe groove for installation.

[0014] The processing unit provides a second pipe groove at the position of the cooling plate assembly groove corresponding to the water outlet. The groove of the second pipe groove near the end of the cooling plate corresponds to the water outlet of the cooling plate, so that the external water supply pipe near the cooling plate can be embedded in the second pipe groove for installation.

[0015] Furthermore, the processing section is provided with a plurality of cooling plate assembly slots, and all the cooling plate assembly slots are evenly distributed along the circumference of the assembly section;

[0018] The processing unit has a third pipe groove between two adjacent cooling plate assembly slots. One end of the third pipe groove corresponds to the water outlet of the cooling plate near the first pipe groove, and the other end corresponds to the water inlet of the cooling plate near the second pipe groove, so that the external adapter pipe connecting the two adjacent cooling plates can be embedded in the processing unit for installation.

[0019] Furthermore, the processing section is provided in multiple parts, and all the processing sections are arranged sequentially along the circumference of the assembly section.

[0020] Furthermore, all of the aforementioned processing parts are integrally formed.

[0033] In summary, the turntable base and turntable device provided by this utility model have the following technical effects:

[0034] 1. The cooling plate is embedded in the cooling plate assembly slot of the processing part, which greatly reduces the height of the external shoe sole mold assembly that would otherwise be increased due to the addition of the cooling plate. This structure completely avoids the problem of the overall height of the mold increasing due to the addition of the cooling plate in the traditional method, thus eliminating the need to set a shim under the shoe mold handle and simplifying the structure.

[0035] 2. Since there is no need to adjust the height of the external sole mold using shims, the external sole mold assembly is directly and stably attached to the cooling plate, avoiding the problems of support rod loosening or displacement caused by traditional shims, and avoiding the problem of reduced mold clamping accuracy caused by raising the installation position of the shoe mold handle after the external sole mold is raised.

[0036] 3. The cooling plate is embedded in the cooling plate assembly slot, that is, the cooling plate is embedded in the processing part to ensure that the shoe mold will not interfere with the cooling plate or pipeline when it is opened, closed or rotated.

[0037] 4. The cooling plate is fixed by the cooling plate mounting slot, eliminating the need for additional shims or mold height adjustments, thus reducing assembly complexity. Simultaneously, the embedded design of the cooling plate facilitates quick disassembly and maintenance, reducing the extra steps required for removing shims and improving equipment maintenance efficiency.

[0038] 5. The cooling plate, whose cooling surface contacts the external sole mold assembly, is flush with the surface of the machining section. That is, the upper surface of the cooling plate is flush with the upper surface of the machining section, thus providing a flat assembly platform.

[0055] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.

[0056] To facilitate understanding of the embodiments of this utility model, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.

[0057] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0059] See Figures 1-15 This utility model discloses a turntable base, which is disposed in a turntable assembly for mounting at least one external shoe sole mold assembly 2 and a shoe film cooling mechanism. The shoe film cooling mechanism has at least one cooling plate 13 for cooling the external shoe sole mold assembly 2. The turntable base includes an assembly part 11 and a processing part 12. The processing part 12 is disposed on the outer periphery of the assembly part 11 and is fixedly connected to the assembly part 11. The processing part 12 is provided with at least one cooling plate assembly groove 121. The cooling plate 13 is embedded in the cooling plate assembly groove 121, and the cooling surface of the cooling plate 13 is in contact with the external shoe sole mold assembly 2.

[0060] The turntable base is mainly used in shoe-making equipment, which generally includes an injection head, a turntable device, and an external sole mold assembly 2. The injection head is used to inject liquid molding material into the external sole mold assembly 2 for sole molding. The turntable device generally includes a turntable assembly, a shoe film cooling mechanism, and a shoe mold operating mechanism. The turntable assembly includes a support base for supporting the turntable base and a shoe mold operating mechanism mounted on the turntable base. The turntable base is mounted on the support base and can rotate on the support base. The shoe mold operating mechanism is used to operate the opening and closing of the external sole mold assembly 2 and the engagement of the shoe last with the external sole mold assembly 2. The shoe mold cooling mechanism is connected to the cooling plate 13, thereby providing coolant to the cooling plate 13 in a circulating manner to ensure the cooling efficiency of the cooling plate 13. The external sole mold assembly 2 is mounted on the cooling plate 13, so that after the injection head injects molding material into the external sole mold assembly 2, the cooling plate 13 rapidly cools the external sole mold assembly 2, thereby ensuring cooling efficiency. Once a single external sole mold component 2 has been injection molded, the corresponding turntable base rotates, allowing for injection molding, cooling, and forming of the next external sole mold component 2.

[0061] Specifically, refer to Figures 1-3 As shown, the assembly part 11 is used to assemble the entire turntable base with the external rotating shaft or external driver to realize the rotation of the turntable base. The processing part 12 is fixedly connected to one side of the assembly part 11 so that the assembly part 11 and the processing part 12 rotate synchronously. The processing part 12 is provided with at least one cooling plate assembly groove 121. The cooling plate 13 is embedded in the cooling plate assembly groove 121, thereby reducing the protrusion height of the cooling plate 13 relative to the processing part 12. Optionally, the cooling plate 13 can be completely sunk into the cooling plate assembly groove 121 for installation, or it can protrude slightly from the cooling plate assembly groove 121, as long as it does not affect the opening and closing of the external shoe sole mold assembly 2. When the cooling plate 13 is embedded in the cooling plate assembly groove 121, the cooling surface of the cooling plate 13 is in contact with the outer shoe sole mold assembly 2. More specifically, the cooling surface of the cooling plate 13 is in contact with the bottom mold 23 of the outer shoe sole mold assembly 2, thereby cooling the bottom mold 23 through the cooling plate 13, so that the bottom mold 23 is cooled down quickly, which is conducive to the efficient cooling and molding of the shoe sole in contact with the bottom mold 23.

[0062] See Figure 2 As shown, in some embodiments, the cooling plate 13 is flush with the surface of the processing section 12 for contacting the cooling surface of the outer sole mold assembly 2.

[0063] Specifically, the cooling surface of the cooling plate 13, which contacts the external sole mold assembly 2, is flush with the surface of the processing section 12. That is, the upper surface of the cooling plate 13 is flush with the upper surface of the processing section 12, thus providing a flat assembly platform. This allows the external sole mold assembly 2 to be placed stably and accurately on the cooling plate 13, reducing assembly difficulties caused by unevenness. Of course, the flat assembly platform provided by the cooling plate 13 and the processing section 12 also facilitates the assembly of other components.

[0064] In some embodiments, the left shoe mold 21 and the right shoe mold 22 can both be disposed on the upper part of the cooling plate 13, so that the cooling plate 13 can cool the bottom mold 23 while also rapidly cooling the left shoe mold 21 and the right shoe mold 22.

[0065] Optionally, the cooling plate mounting slot 121 can be a through-hole structure or a blind-hole structure. The connection method between the cooling plate 13 and the cooling plate mounting slot 121 can also be freely adjusted according to specific needs, as long as the cooling plate 13 is stably mounted in the cooling plate mounting slot 121. The cooling plate 13 can be a metal plate with a high thermal conductivity for heat dissipation, or it can be a structure that can accelerate the heat dissipation of the cooling plate 13 by setting liquid cooling channels 131, finned structures, or cooling fans on the metal plate with a high thermal conductivity. There is no limitation here. Any structure that can accelerate the heat exchange between the bottom mold 23 and the cooling plate 13, as well as the heat dissipation of the cooling plate 13 itself, is acceptable. The metal material for making the cooling plate 13 can be aluminum plate, stainless steel, or other chemically stable metals with high thermal conductivity. There is no limitation here.

[0066] See Figure 4 and Figure 5 As shown, in some embodiments, the cooling plate 13 is provided with a liquid cooling channel 131, which has an inlet 1311 and an outlet 1312, with the inlet 1311 and the outlet 1312 located at opposite ends of the liquid cooling channel 131.

[0067] Specifically, the cooling plate 13 is provided with a liquid cooling channel 131, which has an inlet 1311 and an outlet 1312, located at opposite ends. Correspondingly, the cooling piping can include a supply pipe and an outlet pipe. A supply pipe can be connected to the inlet 1311, and an outlet pipe can be connected to the outlet 1312, allowing external coolant to be introduced into the liquid cooling channel 131 through the inlet 1311. The coolant then flows out of the cooling plate 13 through the outlet 1312. As the coolant flows through the liquid cooling channel 131, it carries away heat from the cooling plate 13, thus maintaining the cooling plate 13 at a low temperature to ensure cooling efficiency. The arrangement of the liquid cooling channels 131 within the cooling plate 13 can be freely selected as needed to effectively maintain the temperature stability of the cooling plate 13. The coolant can be water or other liquids with high specific heat capacity, fast thermal conductivity and stable chemical properties; there are no restrictions on its use.

[0068] See Figure 4 and Figure 5 As shown, in this embodiment, the liquid cooling channel 131 is arranged in a serpentine shape within the cooling plate 13.

[0069] Specifically, the liquid cooling channel 131 is distributed in a serpentine pattern inside the cooling plate 13. By repeatedly turning back and forth, the flow path of the coolant is extended, maximizing the contact time and contact area between the coolant and the cooling plate 13, thereby improving the temperature control effect of the cooling plate 13.

[0070] See Figure 6 and Figure 7 As shown, in some embodiments, the processing unit 12 has a first pipe groove 122 at the position of the cooling plate assembly groove 121 corresponding to the water inlet 1311. The groove of the first pipe groove 122 near the cooling plate 13 corresponds to the water inlet 1311 of the cooling plate 13, so that the water outlet pipe near the cooling plate 13 is embedded in the first pipe groove 122 for installation, preventing interference with the opening and closing of the external shoe sole mold assembly 2. The processing unit 12 has a second pipe groove 123 at the position of the cooling plate assembly groove 121 corresponding to the water outlet 1312. The groove of the second pipe groove 123 near the cooling plate 13 corresponds to the water outlet 1312 of the cooling plate 13, so that the water supply pipe near the cooling plate 13 is embedded in the second pipe groove 123 for installation, preventing interference with the opening and closing of the external shoe sole mold assembly 2.

[0071] Specifically, since the cooling plate 13 is embedded in the cooling plate assembly groove 121, the water inlet 1311 and water outlet 1312 of the cooling plate 13 are generally also partially or completely located in the cooling plate assembly groove 121. This is to facilitate the connection between the water inlet 1311 and the water supply pipe, and the connection between the water outlet 1312 and the water outlet pipe, and also to prevent the water supply pipe and the water outlet pipe from interfering with the opening and closing movements of the external shoe sole mold assembly 2. The processing unit 12 provides a first pipe groove 122 at the position of the water inlet 1311 in the cooling plate assembly groove 121. That is, the processing unit 12 provides a first pipe groove 122 at the position corresponding to the water inlet 1311 of the cooling plate 13 assembled in the cooling plate assembly groove 121. The groove of the first pipe groove 122 near the end of the cooling plate 13 corresponds to the water inlet 1311 of the cooling plate 13, so that the water supply pipe can be connected to the water inlet 1311 after being embedded in the first pipe groove 122. Similarly, the processing unit 12 provides a second pipe groove 123 at the position of the outlet 1312 corresponding to the cooling plate assembly groove 121. That is, the processing unit 12 provides a second pipe groove 123 at the position corresponding to the outlet 1312 of the cooling plate 13 assembled in the cooling plate assembly groove 121. The groove of the second pipe groove 123 near the end of the cooling plate 13 corresponds to the outlet 1312 of the cooling plate 13, so that the water outlet pipe can be inserted into the second pipe groove 123 and connected to the outlet 1312.

[0072] When multiple cooling plate assembly slots 121 are provided, corresponding cooling plates 13 will be assembled in the multiple cooling plate assembly slots 121. Based on the structure of the multiple cooling plates 13, each cooling plate 13 is connected by the above-mentioned water supply pipe and water outlet pipe connection method. That is, the water inlet 1311 of each cooling plate 13 is connected to an independent corresponding water supply pipe, and the water outlet 1312 of each cooling plate 13 is connected to an independent corresponding water outlet pipe. In other words, the multiple cooling plates 13 are connected in parallel so that each cooling plate 13 can have an independent coolant supply, thereby ensuring that the cooling effect of each cooling plate 13 is similar and improving the consistency of the product.

[0073] See Figure 6 , Figure 7 and Figure 8As shown, in some other embodiments, when the processing unit 12 is provided with multiple cooling plate assembly slots 121, all the cooling plate assembly slots 121 are evenly distributed along the outer periphery of the processing unit 12. The processing unit 12 has a first pipe groove 122 near one end of the cooling plate assembly slot 121, and the first pipe groove 122 corresponds to the water inlet 1311 of the cooling plate 13 installed in the cooling plate assembly slot 121. The processing unit 12 has a second pipe groove 123 near the other end of the cooling plate assembly slot 121, and the second pipe groove 123 corresponds to the water outlet 1312 of the cooling plate 13 installed in the cooling plate assembly slot 121. Alternatively, the processing unit 12 may provide a third pipe groove 124 between two adjacent cooling plate assembly grooves 121. One end of the third pipe groove 124 corresponds to the water outlet 1312 of the cooling plate 13 near the side of the first pipe groove 122, and the other end corresponds to the water inlet 1311 of the cooling plate 13 near the side of the second pipe groove 123, so that the adapter pipe in the cooling pipe connecting the two adjacent cooling plates 13 is embedded in the processing unit 12 for installation.

[0074] Specifically, when the processing part 12 is provided with multiple cooling plate assembly slots 121, all the cooling plate assembly slots 121 are evenly distributed along the circumference of the assembly part 11 so that when the assembly part 11 is driven to rotate by an equal angle driver, the assembly part 11 drives the processing part 12 to rotate at equal angles. Correspondingly, the cooling plate assembly slots 121 and the cooling plates 13 located in the cooling plate assembly slots 121 also move at equal angles with the equal angle rotation of the processing part 12. When the rotation angle of the processing part 12 is the same as the included angle between the two adjacent cooling plate assembly slots 121, each rotation of the processing part 12 drives the cooling plates 13 to rotate to the processing position one by one. The processing unit 12 has a first pipe groove 122 at the cooling plate assembly groove 121 near one end of the processing unit 12. That is, the processing unit 12 has a first pipe groove 122 at the position corresponding to the water inlet 1311 of the cooling plate 13 assembled in the cooling plate assembly groove 121 near one end of the processing unit 12. The groove of the first pipe groove 122 near the end of the cooling plate 13 corresponds to the water inlet 1311 of the cooling plate 13, so that the water supply pipe can be inserted into the first pipe groove 122 and connected to the water inlet 1311 of the cooling plate 13. Similarly, the processing unit 12 is provided with a second pipe groove 123 at the cooling plate assembly groove 121 near the other end of the processing unit 12. That is, the processing unit 12 is provided with a second pipe groove 123 at the position corresponding to the water outlet 1312 of the cooling plate 13 assembled in the cooling plate assembly groove 121 near the other end of the processing unit 12. The groove of the second pipe groove 123 near the end of the cooling plate 13 is connected to the water outlet 1312 of the cooling plate 13, so that the water outlet pipe is embedded in the second pipe groove 123 and connected to the water outlet 1312 of the cooling plate 13. In addition to the cooling plate assembly slots 121 located at both ends of the processing section 12, the cooling plates 13 in the cooling plate assembly slot 121 located between the two cooling plate assembly slots 121 are connected in series. Specifically, the processing section 12 provides a third pipe slot 124 between two adjacent cooling plate assembly slots 121. One end of the third pipe slot 124 corresponds to the water outlet 1312 of the cooling plate 13 near the side of the first pipe slot 122, and the other end corresponds to the water inlet 1311 of the cooling plate 13 near the side of the second pipe slot 123, so that the connecting pipe connecting the two adjacent cooling plates 13 is embedded in the processing section 12 for installation.

[0075] The working principle of the above structure after the installation of water supply pipes, water outlet pipes, and connecting pipes is as follows:

[0076] The coolant is supplied through the inlet 1311 of the cooling plate 13 located at one end of the processing section 12, into the liquid cooling channel 131 of the cooling plate 13. After passing through the liquid cooling channel 131, the coolant flows into the transfer pipe through the outlet 1312 of the liquid cooling plate, and then into the inlet 1311 of the adjacent cooling plate 13, and so on, until the coolant cools the outlet 1312 of the last cooling plate 13, and then is discharged to the outside through the outlet pipe, thus achieving the effect of cooling multiple cooling plates 13 in series. In many different application scenarios, the cooling effect when the cooling plates 13 are set up will be affected by factors such as the type of coolant, the flow rate of the coolant, the material of the cooling plate 13, the material of the bottom mold 23 to be cooled, and the shape of the shoe sole to be formed. Correspondingly, based on the fact that the cooling plate 13 can achieve the effect of indirectly cooling the sole to be formed, the specific number of cooling plates 13 connected in series through the third pipe groove 124 and the adapter pipe can be freely selected. The specific number of connected plates is not limited here. It is possible to complete the cooling of all connected cooling plates 13 under the above-mentioned various influencing conditions.

[0077] Example 2

[0078] See Figure 2 and Figure 3 As shown, in some embodiments, there are multiple processing units 12, and all processing units 12 are arranged sequentially along the circumference of the assembly unit 11, and all processing units 12 are fixedly connected to the assembly unit 11.

[0079] Specifically, during the processing of the shoe sole injection molding machine, the assembly section 11 and the processing section 12 rotate synchronously to achieve injection molding of the external shoe sole mold assembly 2. Based on the above structure, in order to increase the number of injections that the assembly section 11 can complete in one revolution, multiple processing sections 12 can be arranged sequentially along the circumference of the assembly section 11. This increases the number of cooling plate assembly slots 121 provided on the processing sections 12, thereby increasing the number of injection molding stations. Optionally, the specific number of processing sections 12 and the spacing between adjacent processing sections 12 can be freely selected according to requirements and are not limited here. It is preferred that all processing sections 12 are equally spaced, so that regardless of whether the external drive is a stepped drive or a stepless drive, it can satisfy the requirement of injection molding of the external shoe sole mold assembly 2 one by one.

[0080] See Figure 2 and Figure 3As shown, based on the structure of multiple processing sections 12, optionally, all processing sections 12 are integrally formed, that is, all processing sections 12 arranged sequentially along the circumference of the assembly section 11 are integrally formed. Correspondingly, in the prior art, referring to patent CN212241855U, the turntable drive mechanism achieves the first distance by using the cooperation of components such as driven grooved wheels, active dials, notched discs, and drive pins, with the distance between the centers of two adjacent driven grooved wheels as the first distance. The turntable is driven to rotate each time according to the above-mentioned first distance. Similarly, the distance between two adjacent sets of external shoe sole mold assemblies 2 arranged above the cooling plate 13 is also the same as the first distance. This ensures that when the driven grooved wheels rotate a distance of the first distance, the external shoe sole mold assembly 2 moves a corresponding distance of the first distance, thereby ensuring that the injection head can always be accurately aligned with the injection hole of the external shoe sole mold assembly 2 corresponding to the opening of the injection head. Therefore, to ensure the accurate alignment of the injection head and the injection hole, the installation position error and tolerance of the driven grooved wheels installed at the bottom of the processing section 12 need to be as small as possible. However, in the existing technology, multiple processing parts 12 are generally screwed onto the turntable one by one, which results in slight errors and tolerances in the installation position of each processing part 12. When these errors and tolerances accumulate, they will affect the fitting accuracy between the driven groove wheel and the driving dial and notched disc, thereby affecting the positioning accuracy of the external shoe sole mold assembly 2, and ultimately causing the injection head to fail to accurately align with the injection hole, affecting the shoe manufacturing quality.

[0081] By integrally molding all machining parts 12, the problems of error and tolerance accumulation caused by installing and adjusting each machining part 12 individually are avoided. This ensures that the position and height of all machining parts 12 are consistent and precise, resulting in more precise cooperation between the driven groove wheel, the driving dial, and the notched disc, guaranteeing that the injection head can always accurately align with each injection hole. Furthermore, compared to multiple independent machining parts 12 fixed one by one with screws, the integral molding structure is more robust and stable, reducing the risk of displacement due to loose or worn screws, improving the smoothness and reliability of equipment operation, and helping to maintain long-term stable production quality. In addition, the integral molding design of all machining parts 12 greatly simplifies the assembly process, eliminating the need to install and adjust each machining part 12 individually, reducing assembly time and complexity, and improving production efficiency. Moreover, this design also reduces the skill requirements for workers, making assembly simpler and faster.

[0082] Alternatively, the assembly part 11 can be circular, and multiple processing parts 12 can be integrally formed into a ring. The ring-shaped processing parts 12 are fitted around the outer periphery of the assembly part 11 to achieve concentric fit. This allows multiple external shoe sole mold components 2 to be injected one by one by rotating the turntable base while the injection nozzle of the external injection molding machine remains stationary.

[0083] See Figure 2 and Figure 3 As shown, furthermore, all machining parts 12 are integrally formed with assembly parts 11. That is, all machining parts 12 are integrally formed with assembly parts 11. This structure not only avoids the accumulation of errors and tolerances caused by installing and adjusting each machining part 12 individually, but also avoids errors and tolerances that arise when the machining parts 12 are subsequently fixedly connected to the assembly parts 11. This eliminates any potential deviations introduced by secondary assembly, ensuring high precision and consistency of the entire system. This makes the fit between the driven groove wheel, the driving dial, and the notched disc more precise, ensuring that the injection head is always accurately aligned with each injection hole. Similarly, the structure in which all machining parts 12 are integrally formed with assembly parts 11 not only reduces assembly errors between machining parts 12 and between machining parts 12 and assembly parts 11, but also significantly enhances the strength and stability of the overall structure. Compared to connecting multiple independent machining parts 12 and assembly parts 11 with screws or other methods, the integrated structure of all machining parts 12 and assembly parts 11 is more robust and reliable, reducing the risk of displacement due to loose or worn screws and improving the smoothness and reliability of equipment operation. Furthermore, the integrated design of all machining parts 12 and assembly parts 11 greatly simplifies the assembly process, eliminating the need for additional fixing and adjustment steps. This not only saves assembly time but also reduces the skill requirements for workers, making the entire assembly process simpler and faster, and improving production efficiency. In addition, because all machining parts 12 and assembly parts 11 are integrated, the turntable base is a seamless whole, reducing the risk of overall performance degradation due to damage to a single component. When maintenance or replacement is required, it also reduces the workload of disassembly and reinstallation, lowers maintenance difficulty and downtime, and facilitates rapid resumption of production.

[0084] See Figure 9 and Figure 10 As shown, in some embodiments, the cooling plate assembly groove 121 is provided through the processing part 12. A limiting member 125 is provided on the side of the cooling plate assembly groove 121 away from the contact surface between the cooling plate 13 and the external shoe sole mold assembly 2. When the cooling plate 13 is assembled in the cooling plate assembly groove 121, the cooling plate 13 abuts against the limiting member 125 to prevent the cooling plate 13 from coming out of the cooling plate assembly groove 121.

[0085] Specifically, the cooling plate assembly groove 121 is designed to run through the entire machining section 12, giving the cooling plate 13 a relatively large assembly space. Correspondingly, the volume of the cooling plate 13 can be designed to be larger, thereby improving heat conduction. A limiting member 125 is provided on the side of the cooling plate assembly groove 121 away from the contact surface between the cooling plate 13 and the external shoe sole mold assembly 2, so that when the cooling plate 13 is assembled in the cooling plate assembly groove 121, the cooling plate 13 abuts against the limiting member 125 to prevent the cooling plate 13 from coming out of the cooling plate assembly groove 121.

[0086] See Figure 9 and Figure 10 As shown, in some embodiments, the limiting member 125 is a limiting plate, which is located on the side of the cooling plate assembly groove 121 away from the contact surface between the cooling plate 13 and the external shoe sole mold assembly 2.

[0087] Specifically, the limiting plate is located on the side of the cooling plate assembly groove 121 away from the contact surface between the cooling plate 13 and the external shoe sole mold assembly 2. This ensures that after the cooling plate 13 is embedded in the cooling plate assembly groove 121, it abuts against the limiting plate, preventing the cooling plate 13 from sliding out of the assembly groove, and does not interfere with the contact between the cooling plate 13 and the external shoe sole mold assembly 2. The limiting plate structure of the limiting member 125 provides a larger contact area for the cooling plate 13, thereby improving the stability of the installation of the cooling plate 13.

[0088] See Figure 9 and Figure 10 As shown, based on the structure of the limiting plate adopted by the limiting member 125, the processing part 12 is provided with a first mounting groove 126 and a second mounting groove 127 on opposite sides of the cooling plate assembly groove 121. One end of the limiting plate is assembled in the first mounting groove 126 and the other end is assembled in the second mounting groove 127.

[0089] Specifically, the first mounting slot 126 is located on one side of the cooling plate assembly slot 121, and the second mounting slot 127 is located on the other side of the cooling plate assembly slot 121, opposite to the first mounting slot 126. During the assembly of the limiting plate, one end of the limiting plate is recessed into the first mounting slot 126 for fixed assembly, and the other end of the limiting plate is recessed into the second mounting slot 127 for fixed assembly. This ensures that the longitudinal dimension of the entire turntable device does not increase due to the addition of the limiting plate, which is beneficial for the management of the longitudinal height. Correspondingly, this structure also reduces additional space requirements, making it particularly suitable for applications with strict requirements on equipment height.

[0090] In addition, after the limiting plate is sunk and installed, it will not affect the movement of the shoe sole molding injection machine during the production process, avoiding operational inconvenience or potential safety hazards caused by the protrusion of the limiting part 125.

[0091] In some embodiments, the limiting member 125 is a limiting protrusion, and multiple limiting protrusions are provided. All multiple limiting protrusions are provided in the cooling plate assembly groove 121 to support the cooling plate 13.

[0092] Specifically, all the limiting protrusions are provided on the groove wall of the cooling plate assembly groove 121 so that when the cooling plate 13 is embedded in the cooling plate assembly groove 121, the cooling plate 13 abuts against the limiting protrusions, thereby providing support for the cooling plate 13. Correspondingly, in order to improve the uniform support of the limiting protrusions on the cooling plate 13, the limiting protrusions can be set at equal intervals. Preferably, when the cooling plate assembly groove 121 is rectangular, a limiting protrusion can be provided in the middle of each of the four side walls of the cooling plate assembly groove 121, thereby achieving uniform support for the cooling plate 13 and avoiding deformation or damage caused by uneven local stress.

[0093] In some embodiments, multiple limiting blocks can be connected end to end to form a limiting step surface, which supports the cooling plate 13.

[0094] In some embodiments, the cooling plate 13 is embedded in the cooling plate assembly groove 121 and is interference-fitted with the cooling plate assembly groove. By embedding and installing the cooling plate 13 in the cooling plate assembly groove 121, the stability of the cooling plate 13 in the cooling plate assembly groove 121 can be guaranteed, and the gap between the cooling plate 13 and the processing part 12 can be greatly reduced, ensuring smooth movement of the external shoe sole mold assembly 2.

[0095] This utility model also provides a turntable device, including a driver and a turntable base, wherein the driver is connected to the assembly part 11 in a transmission connection.

[0096] Specifically, the driver is connected to the assembly part 11 of the turntable base, thereby driving the turntable base to rotate, so that the external injection molding machine can perform injection molding on the external shoe sole mold assembly 2 located on the processing part 12 one by one.

[0097] The present invention also provides a turntable device, including a driver 4 and a turntable base, wherein the driver 4 is connected to the assembly part 11 in a transmission manner.

[0098] Specifically, the driver 4 is connected to the assembly part 11 of the turntable base, thereby driving the turntable base to rotate, thus enabling the external injection molding machine to perform injection molding on the external shoe sole mold assembly 2 located on the processing part 12 one by one. Optionally, the driver 4 can be a motor with a reducer connected to it, and the motor is connected to the turntable base through the reducer. Of course, the driver 4 can also be a stepped drive mechanism, and correspondingly, the turntable base can also be driven by a stepped drive mechanism, thereby driving the turntable base to rotate at a fixed rotation angle.

[0099] In some embodiments, the turntable drive mechanism includes a plurality of driven pulleys fixed to the bottom of the turntable base, and a motor, a reducer, a drive dial 61, a notched disc 62, and a pin 63 mounted on the base 8. The motor is connected to the input end of the reducer via a belt, and the output end of the reducer is equipped with the drive dial 61. The drive dial 61 is equipped with the notched disc 62 and the pin 63. The notched disc 62 is adapted to the positioning groove of the driven pulley, and the pin 63 is adapted to the side wall of the notched disc 62. When the drive dial 61 rotates, the notched disc 62 and the pin 63 act sequentially on the positioning groove and side wall of the notched disc 62 to realize the rotation of the turntable base.

[0100] The distance between the centers of two adjacent driven grooved wheels is the first distance. The drive turntable 1 rotates each time based on the first distance. Similarly, the distance between two adjacent sets of external shoe sole mold assemblies set above the cooling plate 13 is also the same as the first distance. This ensures that when the driven grooved wheel rotates a distance of one first distance, the external shoe sole mold assembly moves a distance of one first distance, thereby ensuring that the injection head can always be accurately aligned with the injection hole of the external shoe sole mold assembly corresponding to the opening of the injection head.

[0101] Since the turntable drive mechanism is existing technology, it will not be described in detail here. For details, please refer to patent CN212241855U.

[0102] See Figure 12 and Figure 13 As shown, in some embodiments, the shoe-making equipment further includes a lubrication assembly, which includes an oil tank 51, an oil pump 52, and an oil delivery pipe 53. The oil tank 51 has an oil outlet and an oil inlet. The oil pump 52 is mounted on the oil delivery pipe 53. One end of the oil delivery pipe 53 is provided with a filter screen and enters the oil tank 51 through the oil outlet to deliver the lubricating oil in the oil tank 51 to the other end of the oil delivery pipe 53 via the oil pump 52. The other end of the oil delivery pipe 53 is provided with at least one drip nozzle, which corresponds to and is located above the turntable drive mechanism 4, for dripping the lubricating oil onto the turntable drive mechanism 4.

[0103] In some embodiments, two oil drip ports are provided on the oil supply pipe 53, located above the side surfaces of the notched disc 62 and the pin 63, respectively, for dripping oil onto the side surfaces of the notched disc 62 and the pin 63. During the contact process between the notched disc 62 and the pin 63 and the driven groove wheel, the lubricating oil is transferred to the driven groove wheel, thereby achieving lubrication of the entire turntable drive mechanism 4.

[0104] Alternatively, a copper pipe 54 can be installed in the section of the oil pipeline 53 where the oil drip port is located, thereby improving the stability of the section and ensuring that the lubricating oil dripping from the oil drip port can drip to the predetermined position.

[0105] In some embodiments, in order to facilitate the collection and recycling of lubricating oil, a first oil receiving plate 71 is provided below the active dial 61, the notched disc 62 and the dial pin 63. The first oil receiving plate 71 is provided with an oil return port 711, which is connected to the oil inlet through an oil return pipe, so as to collect the lubricating oil in the first oil receiving plate 71.

[0106] Furthermore, since the driven grooved wheel comes into contact with lubricating oil during its contact with the notched disc 62 and the pin 63, an arc-shaped second oil receiving tray 72 is provided vertically below the driven grooved wheel to facilitate the collection of lubricating oil on all driven grooved wheels. The second oil receiving tray 72 has slots at both ends, and both slots are located above the first oil receiving tray 71, so that the lubricating oil in the second oil receiving tray 72 can flow into the first oil receiving tray 71 and then be recycled and reused through the connection between the first oil receiving tray 71 and the oil tank 51.

[0107] participate Figure 12 , Figure 14 and Figure 15 As shown in some embodiments, the base 8 is provided with multiple support components 81 at equal intervals. Each support component 81 includes a support base 811, a support member 812, a screw 813, a nut 814, a washer 815, and a flexible pad 816. One end of the support member 812 is inserted into the support base 811, and the other end is connected to a wear-resistant plate 817. The flexible pad 816 and the washer 815 are sequentially arranged inside the support base 811. The support member 812 contacts the flexible pad 816. The screw 813 is inserted into the support base 811 from the opposite end of the support member 812 and is threaded into the support base 811. By the insertion length of the screw 813 relative to the support base 811, the washer 815, the flexible pad 816, and the support member 812 can be pushed to move sequentially, thereby adjusting the overall height of each support component 81 and adapting to different assembly environments, ensuring that the wear-resistant plate 817 of each support component 81 can be stably contacted with the turntable base. Nut 814 is fitted onto screw 813 and located outside support 811, thereby preventing screw 813 from moving.

[0108] Alternatively, the flexible pad 816 can be made of rubber, allowing for adaptive adjustments to minor height differences after the screw 813 has been adjusted.

[0109] Optionally, the wear-resistant plate 817 has a protrusion 8171 on the side facing the support member 812. The support member 812 is used to install the protrusion 8171. One end of the support member 812 is provided with a groove 8121 that mates with the protrusion 8171. By assembling the protrusion 8171 into the groove 8121, and then welding the wear-resistant plate 817 and the support member 812, the connection strength and connection accuracy can be improved.

[0110] In addition, due to the weight of the turntable base, it will rub against the wear-resistant plate 817. During long-term friction, the heat generated by the wear-resistant plate 817 and the turntable base will accelerate surface damage to both, increase friction, and affect the normal use of the turntable base.

[0111] To address the aforementioned issues, the wear-resistant plate 817 is made of cast iron, while the portion of the turntable base that contacts the wear-resistant plate 817 is made of wrought iron. The hardness of cast iron is greater than that of wrought iron, which can greatly alleviate the problem of increased friction caused by wear.

[0112] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
