Description

Technical Field

[0001] The present invention relates to the technical field of shoe-making equipment, and particularly to a turntable assembly and a turntable device for shoe-making equipment. Background Art

[0002] In traditional injection shoe-making equipment, in order to accelerate the molding process of shoe soles, the formed shoes are usually cooled by supplying circulating cooling water to the left and right shoe molds. This cooling method introduces cooling water into the interior of the shoe mold and utilizes the principle of heat conduction to take away the heat of the shoe sole, accelerating the reduction of the temperature of the shoe sole, thereby improving the molding efficiency of the shoe sole. However, since the thickness of the shoe sole is relatively small and the contact area between the left and right shoe molds and the shoe sole to be molded is limited, the effect of accelerating cooling is limited, and the improvement of the molding efficiency of the shoe sole is not significant.

[0003] In order to further optimize the cooling effect, subsequent technical improvements have adopted the method of using a bottom cooling plate for cooling. Compared with the area of the side surface of the shoe sole, the bottom area of the shoe sole is larger. Therefore, by arranging a cooling plate under the bottom mold of the shoe mold and cooling the bottom mold through the cooling plate, the temperature of the bottom mold can be kept at a temperature that can effectively cool the shoe sole, and then the cooling and molding of the shoe sole can be completed. Correspondingly, by indirectly cooling the molding of the shoe sole through the cooling plate, the cooling efficiency can be greatly improved, and thus the molding efficiency can be improved. This improvement method is to directly install the bottom cooling plate on the upper surface of the original turntable base so that it fits with the bottom mold, thereby reducing the modification cost. However, this modification method brings new problems: due to the installation of the bottom cooling plate, the overall height of the shoe mold increases, resulting in an increase in the operating height of the operator, which affects the convenience of operation.

[0004] In addition, the shoe mold usually adopts a design that opens left and right. In order to ensure that the left and right shoe molds do not interfere with the bottom cooling plate during rotation, it is necessary to add a spacer block at the bottom of the shoe mold handle during modification. These spacer blocks are sleeved on the support rod connecting the turntable base and the turntable top seat, causing the shoe mold handle to be far away from the bottom fixing point of the support rod. Although this design solves the interference problem, it reduces the overall structural stability, thereby affecting the clamping accuracy. The decrease in clamping accuracy will result in dimensional deviations or surface defects during the molding process of the shoe sole, affecting the product quality. Summary of the Invention

[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a turntable assembly and a turntable device for shoe-making equipment, which can solve the problem that it is necessary to set spacer blocks to raise the shoe mold handle and the left and right shoe molds to prevent the left and right shoe molds from interfering with the cooling plate due to the addition of the cooling plate.

This structure completely avoids the problem of the overall height increase of the mold caused by the addition of the cooling plate in the traditional method, so that it is not necessary to set a heightening block under the shoe mold handle, simplifying the structure.

[0041] 2. Since it is not necessary to adjust the height of the external shoe sole mold through a heightening block, the external shoe sole mold assembly is directly and stably attached to the cooling plate, avoiding the problems of loosening or deviation of the support rod caused by the traditional heightening block, and avoiding the problem of reduced mold clamping accuracy brought about by correspondingly increasing the installation position of the shoe mold handle after the external shoe sole mold is heightened.

[0042] 3. The cooling plate is embedded in the cooling plate assembly groove, that is, the cooling plate is embedded in the processing part, ensuring that the shoe mold will not interfere with the cooling plate or the pipeline when opening, closing or rotating.

[0043] 4. The cooling plate is fixed through the cooling plate assembly groove, without the need to additionally install a heightening block or adjust the mold height, reducing the assembly complexity. At the same time, the embedded design of the cooling plate is convenient for quick disassembly and maintenance, reducing the additional operation steps brought about by the disassembly of the heightening block and improving the equipment maintenance efficiency.

[0044] 5. When the cooling plate is installed in the cooling plate assembly groove, the water inlet and outlet of the cooling plate will be partially or completely inside the cooling plate assembly groove. Correspondingly, it is difficult to connect the water inlet and outlet of the cooling plate to the water supply pipe and the water outlet pipe. The first pipe groove and the second pipe groove are provided to facilitate the installation of the water supply pipe and the water outlet pipe, and the first pipe groove and the second pipe groove are used for embedded assembly of the water supply pipe and the water outlet pipe.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0065] Refer to Figures 1 - 15 , the present invention discloses a turntable base for a shoe-making device, which is arranged in a turntable assembly for installing at least one external sole mold assembly 2 and a shoe mold cooling mechanism. The shoe mold cooling mechanism has at least one cooling plate 13 for cooling the external sole mold assembly 2. The turntable base includes an assembly part 11 and a machining part 12. The machining part 12 is arranged on the outer peripheral side of the assembly part 11 and is fixedly connected to the assembly part 11. The machining part 12 is provided with at least one cooling plate assembly groove 121, and the cooling plate 13 is embedded in the cooling plate assembly groove 121. The cooling surface of the cooling plate 13 is attached to the external sole mold assembly 2.

[0066] The turntable base is mainly used in shoe-making equipment. Generally, the shoe-making equipment includes an injection head, a turntable device, and an external sole mold assembly 2. The injection head is used to inject liquid material into the external sole mold assembly 2 for sole molding. The turntable device generally includes a turntable assembly, a turntable drive mechanism, a shoe mold cooling mechanism, and a shoe mold operating mechanism. Among them, the turntable assembly includes a support base for supporting the turntable base and a shoe mold operating mechanism arranged on the turntable base. The turntable base is assembled 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 cooperation between the shoe last and the external sole mold assembly 2. The shoe mold cooling mechanism includes a cooling machine, a cooling pipeline, and a cooling plate 13. The cooling machine is connected to the cooling plate 13 through the cooling pipeline and continuously circulates water to the cooling plate 13, so as to be able to circulate and supply coolant to the cooling plate 13 to ensure the cooling efficiency of the cooling plate 13. The external sole mold assembly 2 is arranged on the cooling plate 13. After the injection head injects into the external sole mold assembly 2, the cooling plate 13 quickly cools the external sole mold assembly 2 to ensure the cooling efficiency. When the injection of a single external sole mold assembly 2 is completed, correspondingly, the turntable base rotates, and then the injection, cooling, and molding of the next external sole mold assembly 2 can be carried out.

[0067] Specifically, refer to Figures 1 - 3As shown in the figure, the assembly part 11 is used to assemble the entire turntable base with an external rotating shaft or an external drive 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. At least one cooling plate assembly groove 121 is provided on the processing part 12, and the cooling plate 13 is embedded in the cooling plate assembly groove 121, thereby reducing the protruding 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 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 attached to the external sole mold assembly 2. More specifically, the cooling surface of the cooling plate 13 is attached to the bottom mold 23 of the external sole mold assembly 2, so as to cool the bottom mold 23 through the cooling plate 13, enabling the bottom mold 23 to cool down quickly and facilitating the efficient cooling and molding of the sole in contact with the bottom mold 23.

[0068] In some embodiments, the left shoe mold 21 and the right shoe mold 22 can also be arranged above the cooling plate 13, so that while the cooling plate 13 cools the bottom mold 23, it also quickly cools the left shoe mold 21 and the right shoe mold 22.

[0069] Optionally, the cooling plate assembly groove 121 can be a through-hole structure or a blind-hole structure, and the connection method between the cooling plate 13 and the cooling plate assembly groove 121 can also be freely adjusted according to specific requirements, as long as the cooling plate 13 can be stably assembled in the cooling plate assembly groove 121. The cooling plate 13 can use a metal plate with a high thermal conductivity coefficient for heat dissipation, or it can also use a structure such as a liquid cooling channel 131, a fin structure or a cooling fan arranged on the metal plate with a high thermal conductivity coefficient to accelerate the heat dissipation of the cooling plate 13. There is no limitation here, and any structure that can accelerate the heat exchange between the bottom mold 23 and the cooling plate 13 and the heat dissipation of the cooling plate 13 itself can be used. The metal material for making the cooling plate 13 can be selected from metals with stable chemical properties and high thermal conductivity coefficients such as aluminum plates and stainless steels, and there is no limitation here.

[0070] Refer to Figure 4 and Figure 5 As shown in the figure, in some embodiments, a liquid cooling channel 131 is provided in the cooling plate 13. The liquid cooling channel 131 has a water inlet 1311 and a water outlet 1312, and the water inlet 1311 and the water outlet 1312 are respectively located at both ends of the liquid cooling channel 131.

[0071] Specifically, a liquid cooling channel 131 is provided inside the cooling plate 13. The liquid cooling channel 131 has a water inlet 1311 and a water outlet 1312, and the water inlet 1311 and the water outlet 1312 are respectively located at both ends of the liquid cooling channel 131. Correspondingly, the cooling pipeline can include a water supply pipe and a water outlet pipe. The water supply pipe can be connected to the water inlet 1311, and the water outlet pipe can be connected to the water outlet 1312. Thus, the external coolant is introduced into the liquid cooling channel 131 from the water inlet 1311, and then the coolant flows out of the cooling plate 13 through the water outlet 1312. When the coolant flows in the liquid cooling channel 131, it will take away the heat in the cooling plate 13, so that the cooling plate 13 always maintains a low temperature state to ensure the cooling efficiency. Among them, the arrangement of the liquid cooling channel 131 in the cooling plate 13 can be freely selected as needed, as long as the temperature of the cooling plate 13 can be effectively kept stable. The coolant can be water or other liquids with a high specific heat capacity, fast heat conduction and stable chemical properties, and is not limited here.

[0072] Refer to Figure 4 and Figure 5 As shown, in this embodiment, the liquid cooling channel 131 is arranged in a serpentine shape and wound inside the cooling plate 13.

[0073] Specifically, the liquid cooling channel 131 is distributed in a serpentine shape inside the cooling plate 13. By repeatedly turning back to extend the coolant flow path, the contact time and contact area between the coolant and the cooling plate 13 are maximized, thereby improving the control effect on the temperature of the cooling plate 13.

[0074] Refer to Figure 6 and Figure 7 As shown, in some embodiments, the processing part 12 is provided with a first pipe groove 122 at the position of the cooling plate assembly groove 121 corresponding to the water inlet 1311. The notch 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 and installed in the first pipe groove 122 to prevent interference with the opening and closing of the external sole mold assembly 2. The processing part 12 is provided with a second pipe groove 123 at the position of the cooling plate assembly groove 121 corresponding to the water outlet 1312. The notch 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 and installed in the second pipe groove 123 to prevent interference with the opening and closing of the external sole mold assembly 2.

[0075] Specifically, since the cooling plate 13 is embedded in the cooling plate assembly groove 121, correspondingly, the water inlet 1311 and the water outlet 1312 of the cooling plate 13 are generally partially or entirely located within the cooling plate assembly groove 121. To facilitate the connection between the water inlet 1311 and the water supply pipe and between the water outlet 1312 and the water discharge pipe, and also to prevent interference with the mold opening and closing movements of the external sole mold assembly 2 by the water supply pipe and the water discharge pipe, the processing part 12 is provided with a first pipe groove 122 at the position corresponding to the water inlet 1311 of the cooling plate assembly groove 121, that is, the processing part 12 sets the 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 notch of the first pipe groove 122 near the cooling plate 13 corresponds to the water inlet 1311 of the cooling plate 13, so that after the water supply pipe is embedded in the first pipe groove 122, it can be correspondingly connected to the water inlet 1311. Similarly, the processing part 12 is provided with a second pipe groove 123 at the position corresponding to the water outlet 1312 of the cooling plate assembly groove 121, that is, the processing part 12 sets the 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. The notch of the second pipe groove 123 near the cooling plate 13 corresponds to the water outlet 1312 of the cooling plate 13, so that after the water discharge pipe is embedded in the second pipe groove 123, it can be correspondingly connected to the water outlet 1312.

[0076] When multiple cooling plate assembly grooves 121 are provided, correspondingly, the corresponding cooling plates 13 will be assembled in the multiple cooling plate assembly grooves 121. On the basis of the structures of the above multiple cooling plates 13, for each cooling plate 13, the above connection method of the water supply pipe and the water discharge pipe is adopted for connection, that is, an independently corresponding water supply pipe is connected to the water inlet 1311 of each cooling plate 13, and an independently corresponding water discharge pipe is connected to the water outlet 1312 of each cooling plate 13. That is, 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 effects of each cooling plate 13 are close and improving the product consistency.

[0077] Refer to Figure 6 、 Figure 7 and Figure 8As shown, in some other embodiments, when the processing part 12 is provided with a plurality of cooling plate assembly grooves 121, all the cooling plate assembly grooves 121 are evenly distributed along the outer periphery of the processing part 12. The processing part 12 is provided with a first pipe groove 122 at the cooling plate assembly groove 121 near one end thereof, and the first pipe groove 122 corresponds to the water inlet 1311 of the cooling plate 13 installed in the cooling plate assembly groove 121. The processing part 12 is provided with a second pipe groove 123 at the cooling plate assembly groove 121 near the other end thereof, and the second pipe groove 123 corresponds to the water outlet 1312 of the cooling plate 13 installed in the cooling plate assembly groove 121. Alternatively, the processing part 12 is provided with 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 on the side close to the first pipe groove 122, and the other end corresponds to the water inlet 1311 of the cooling plate 13 on the side close to the second pipe groove 123, so that the adapter pipe in the cooling pipeline connecting two adjacent cooling plates 13 is embedded in the installation of the processing part 12.

[0078] Specifically, when the processing part 12 is provided with a plurality of cooling plate assembly grooves 121, all the cooling plate assembly grooves 121 are evenly distributed along the circumferential direction 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 grooves 121 and the cooling plates 13 located in the cooling plate assembly grooves 121 also perform equal-angle movements as the processing part 12 rotates at equal angles. When the rotation angle of the processing part 12 is the same as the included angle between two adjacent cooling plate assembly grooves 121, that is, each rotation of the processing part 12 drives the cooling plate 13 to rotate to the processing position one by one. The processing part 12 is provided with a first pipe groove 122 at the cooling plate assembly groove 121 near one end of the processing part 12, that is, the first pipe groove 122 is arranged 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 part 12. The notch of the first pipe groove 122 near one end of the cooling plate 13 corresponds to the water inlet 1311 of the cooling plate 13, so that after the water supply pipe is inserted into the first pipe groove 122, it can be correspondingly connected to the water inlet 1311 of the cooling plate 13. Similarly, the processing part 12 is provided with a second pipe groove 123 at the cooling plate assembly groove 121 near the other end of the processing part 12, that is, the second pipe groove 123 is arranged 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 part 12. The notch of the second pipe groove 123 near one end of the cooling plate 13 is correspondingly connected to the water outlet 1312 of the cooling plate 13, so that after the water outlet pipe is inserted into the second pipe groove 123, it can be correspondingly connected to the water outlet 1312 of the cooling plate 13. Except for the cooling plate assembly grooves 121 at both ends of the processing part 12, the cooling plates 13 in the cooling plate assembly grooves 121 between the above two cooling plate assembly grooves 121 are connected in series. Specifically, the processing part 12 is provided with 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 first pipe groove 122, and the other end corresponds to the water inlet 1311 of the cooling plate 13 near the second pipe groove 123, so that the adapter pipe connecting two adjacent cooling plates 13 can be inserted into the processing part 12 for installation.

[0079] The working principle of the above structure after installing the water supply pipe, the water outlet pipe and the adapter pipe is as follows:

[0080] The water supply pipe allows the coolant to enter the liquid cooling channel 131 of the cooling plate 13 through the water inlet 1311 at one end of the processing part 12. After passing through the liquid cooling channel 131, the coolant flows into the adapter pipe through the water outlet 1312 of the liquid cooling plate, and then enters the water inlet 1311 of the cooling plate 13 adjacent to the cooling plate 13 after passing through the adapter pipe, and so on. Until the coolant flows out of the water outlet 1312 of the last cooling plate 13, it is discharged to the outside through the water outlet pipe, thus achieving the effect of series cooling of multiple cooling plates 13. In many different application scenarios, 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 sole to be molded will all affect the cooling effect when the cooling plate 13 is set. Correspondingly, on the basis that the cooling plate 13 can achieve the effect of indirectly cooling the sole to be molded, 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 series connections is not limited here. Based on the above various influencing conditions, it is sufficient to complete the cooling of all the cooling plates 13 connected in series.

[0081] Embodiment 2

[0082] Refer to Figure 2 and Figure 3 As shown, in some embodiments, there are multiple processing parts 12, and all the processing parts 12 are arranged in sequence along the circumferential direction of the assembly part 11, and all the processing parts 12 are fixedly connected to the assembly part 11.

[0083] Specifically, during the processing of the sole injection molding machine, the assembly part 11 and the processing part 12 rotate synchronously to realize the injection molding of the external sole mold assembly 2. On the basis of the above structure, in order to increase the number of injection moldings that the assembly part 11 can complete in one rotation, multiple processing parts 12 can be arranged in sequence along the circumferential direction of the assembly part 11, so as to increase the number of cooling plate assembly grooves 121 provided on the processing part 12, and further increase the number of injection molding stations. As an option, the specific number of processing parts 12 and the distance between adjacent processing parts 12 can be freely selected according to requirements and are not limited here. Preferably, all the processing parts 12 are arranged at equal intervals, so as to realize that whether the external drive is a polar drive or a non-polar drive, it can meet the requirement of injecting the external sole mold assembly 2 one by one.

[0084] Refer to Figure 2 and Figure 3As shown, on the basis of arranging multiple processing parts 12, optionally, all the processing parts 12 are integrally formed, that is, all the processing parts 12 arranged in sequence along the circumferential direction of the assembly part 11 are integrally formed. Correspondingly, in the prior art, as shown in the patent CN212241855U, the turntable driving mechanism realizes that the distance between the centers of two adjacent driven sprockets is the first distance through the cooperation of components such as the driven sprocket, the driving dial, the notched disc, and the driving pin. The driving turntable rotates each time with the above first distance as the standard. Similarly, the distance between two adjacent sets of external sole mold assemblies 2 arranged above the cooling plate 13 is also the same as the first distance. Thus, when the driven sprocket rotates a distance of a first distance, the external sole mold assembly 2 correspondingly moves a distance of a first distance, thereby ensuring that the injection head can always accurately align with the injection hole of the external sole mold assembly 2 corresponding to the opening of the injection head. Therefore, if the accurate alignment between the injection head and the injection hole is to be ensured, the installation position error and tolerance of the driven sprocket installed at the bottom of the processing part 12 need to be as small as possible. However, in the prior art, multiple processing parts 12 are generally screwed onto the turntable one by one with screws, resulting in slight errors and tolerances in the installation positions of each processing part 12. When these errors and tolerances accumulate, it will affect the fitting accuracy between the driven sprocket, the driving dial, and the notched disc, thereby affecting the positioning accuracy of the external sole mold assembly 2, and ultimately causing the injection head to be unable to accurately align with the injection hole, affecting the quality of shoe manufacturing.

[0085] The above-mentioned method of integrally forming all the processing parts 12 avoids the problem of error and tolerance accumulation caused by installing and adjusting each processing part 12 one by one, ensuring that the position heights of all the processing parts 12 are consistent and accurate, thereby making the cooperation between the driven sprocket, the driving dial, and the notched disc more precise, and ensuring that the injection head can always accurately align with each injection hole. Moreover, compared with multiple independent processing parts 12 fixed one by one with screws, the integrally formed structure is more solid and stable, reducing the displacement risk caused by screw loosening or wear, improving the smoothness and reliability of equipment operation, and helping to maintain long-term stable production quality. In addition, the design of integrally forming all the processing parts 12 greatly simplifies the assembly process, eliminating the need to install and adjust each processing part 12 one by one, reducing the assembly time and complexity, and improving the production efficiency. Furthermore, this design also reduces the requirements for workers' skills, making the assembly more simple and fast.

[0086] Optionally, the assembly part 11 can be circular, and multiple processing parts 12 can be integrally formed into a ring shape. The ring-shaped processing part 12 is sleeved on the outer periphery of the assembly part 11 to achieve concentric cooperation. Thus, when the injection nozzle of the external injection molding machine remains stationary, only by rotating the turntable base, multiple external sole mold assemblies 2 can be injected one by one.

[0087] Refer toFigure 2 and Figure 3 As shown in Figure 3 , further, all the processing parts 12 are integrally formed with the assembly part 11. That is, all the processing parts 12 and the assembly part 11 are integrally formed. The above structure can not only avoid the problem of error and tolerance accumulation caused by individually installing and adjusting each processing part 12, but also avoid the errors and tolerances generated when fixedly connecting the processing part 12 and the assembly part 11 subsequently. Thus, any potential deviation introduced by secondary assembly is eliminated, ensuring the high precision and consistency of the whole system, so that the cooperation between the driven sprocket, the driving dial and the notched disc is more accurate, and ensuring that the injection head always accurately aligns with each injection hole. Similarly, the structure in which all the processing parts 12 are integrally formed with the assembly part 11 not only reduces the assembly errors between the processing parts 12 and between the processing part 12 and the assembly part 11, but also greatly enhances the strength and stability of the overall structure. Compared with connecting multiple independent processing parts 12 and the assembly part 11 together by screws or other means, the structure in which all the processing parts 12 and the assembly part 11 are integrally formed is more solid and reliable, reducing the risk of displacement caused by screw loosening or wear, and improving the smoothness and reliability of the equipment operation. Moreover, the design of directly integrally forming all the processing parts 12 and the assembly part 11 greatly simplifies the assembly process, without the need for additional fixing and adjusting steps. This not only saves the assembly time, but also reduces the requirements for workers' skills, making the whole assembly process more simple and fast, and improving the production efficiency. In addition, since all the processing parts 12 and the assembly part 11 are integrally formed, the turntable base is a seamless whole, reducing the risk of overall performance degradation caused by damage to a single component. When maintenance or replacement is required, the workload of disassembly and reinstallation can also be reduced, the maintenance difficulty and downtime are reduced, and it is convenient to quickly resume production.

[0088] Referring to Figure 9 and Figure 10 As shown in Figure 10 , in some embodiments, the cooling plate assembly groove 121 runs through the processing part 12. A limiting part 125 is provided on one side of the cooling plate assembly groove 121 away from the joint surface of the cooling plate 13 and the external 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 part 125 to prevent the cooling plate 13 from slipping out of the cooling plate assembly groove 121.

[0089] Specifically, the cooling plate assembly groove 121 is designed to penetrate the entire processing part 12, enabling the cooling plate 13 to have a relatively large assembly space. Correspondingly, the volume of the cooling plate 13 can be designed to be larger, thereby increasing the heat conduction capacity. A limiting member 125 is provided on one side of the cooling plate assembly groove 121 away from the contact surface between the cooling plate 13 and the external 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 disengaging from the cooling plate assembly groove 121.

[0090] Refer to Figure 9 and Figure 10 As shown, in some embodiments, the limiting member 125 is a limiting plate, and the limiting plate is provided on one side of the cooling plate assembly groove 121 away from the contact surface between the cooling plate 13 and the external sole mold assembly 2.

[0091] Specifically, the limiting plate is provided on one side of the cooling plate assembly groove 121 away from the contact surface between the cooling plate 13 and the external sole mold assembly 2. This can ensure that after the cooling plate 13 is inserted into 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 not interfering with the contact between the cooling plate 13 and the external sole mold assembly 2. The structure of the limiting member 125 using a limiting plate can provide a larger contact area for the cooling plate 13, thereby improving the installation stability of the cooling plate 13.

[0092] Refer to Figure 9 and Figure 10 As shown, on the basis of the structure of the limiting member 125 using a limiting plate, the processing part 12 is respectively provided with a first installation groove 126 and a second installation groove 127 on two opposite sides of the cooling plate assembly groove 121, and one end of the limiting plate is assembled in the first installation groove 126, and the other end is assembled in the second installation groove 127.

[0093] Specifically, the first installation groove 126 is located on one side of the cooling plate assembly groove 121, and the second installation groove 127 is located on the other side of the cooling plate assembly groove 121, opposite to the first installation groove 126. When the limiting plate is assembled, one end of the limiting plate sinks into the first installation groove 126 for fixed assembly, and the other end of the limiting plate sinks into the second installation groove 127 for fixed assembly, so that the size of the entire turntable device in the longitudinal direction will not increase due to the addition of the limiting plate, which is beneficial to the management of the longitudinal height. Correspondingly, this structure also reduces the additional space requirement and is particularly suitable for application scenarios with strict requirements on the equipment height.

[0094] In addition, after the limiting plate sinks into the installation, it will not affect the movement of the sole forming injection molding machine during the production process, avoiding the inconvenience of operation or potential safety hazards caused by the protrusion of the limiting member 125.

[0095] In some embodiments, the limiting member 125 is a limiting protrusion, and a plurality of limiting protrusions are provided. The plurality of limiting protrusions are all disposed in the cooling plate assembly groove 121 to support the cooling plate 13 .

[0096] Specifically, all the limiting protrusions are arranged 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 and the limiting protrusions are abutted against each other, thereby forming 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 arranged at equal intervals. Preferably, when the cooling plate assembly groove 121 is rectangular, a limiting protrusion can be arranged 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 force.

[0097] See also Figure 6 As shown, in some embodiments, the cooling surface of the cooling plate 13 for contacting the outer sole mold assembly 2 is flush with the surface of the processed portion 12 .

[0098] Specifically, the cooling surface of the cooling plate 13 that contacts the external sole mold assembly 2 is flush with the surface of the processing portion 12, that is, the upper surface of the cooling plate 13 is flush with the upper surface of the processing portion 12, so that the cooling plate 13 and the processing portion 12 cooperate to provide a flat assembly platform. This allows the external sole mold assembly 2 to be placed smoothly and accurately on top of the cooling plate 13, reducing assembly difficulties caused by unevenness. Of course, the cooling plate 13 and the processing portion 12 cooperate to provide a flat assembly platform, which also facilitates the assembly of other parts.

[0099] The present invention further provides a turntable device, comprising a driver 4 and a turntable base, wherein the driver 4 is transmission-connected to the assembly portion 11 .

[0100] Specifically, the driver 4 is connected to the assembly part 11 of the turntable base by transmission, so as to drive the turntable base to rotate, thereby realizing that the external injection molding machine performs injection molding on the external sole mold assembly 2 arranged on the processing part 12 one by one. As an option, the driver 4 can be a motor, and the motor is connected to the reducer by transmission, and the motor is connected to the turntable base by transmission through the reducer. Of course, the driver 4 can also be a polarized driving mechanism, and correspondingly, the turntable base can also drive the turntable base by the polarized driving mechanism, so as to drive the turntable base to rotate according to a fixed rotation angle.

[0101] In some embodiments, the turntable driving mechanism includes a plurality of driven sprocket wheels fixed to the bottom of the turntable base, and a motor, a speed reducer, a driving 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 speed reducer by a belt. The output end of the speed reducer is equipped with the driving dial 61, and the notched disc 62 and the pin 63 are mounted on the driving dial 61. The notched disc 62 is adapted to the positioning groove of the driven sprocket wheel, and the pin 63 is adapted to the side wall of the notched disc 62. When the driving dial 61 rotates, the notched disc 62 and the pin 63 will act on the positioning groove and the side wall of the notched disc 62 in sequence to realize the rotation of the turntable base.

[0102] The distance between the centers of two adjacent driven sprocket wheels is the first distance. The turntable 1 is driven to rotate each time with the first distance as the standard. Similarly, the distance between two adjacent external sole mold assemblies arranged above the cooling plate 13 is also the same as the first distance. Thus, when the driven sprocket wheel rotates a distance of the first distance, the external sole mold assembly correspondingly moves a distance of the first distance, so as to ensure that the injection head can always accurately align with the injection hole of the external sole mold assembly corresponding to the opening of the injection head.

[0103] Since the turntable driving mechanism is a prior art, it will not be elaborated here too much. For details, refer to the patent CN212241855U.

[0104] Refer to Figure 12 and Figure 13 As shown, in some embodiments, the shoe-making equipment further includes a lubrication assembly. The lubrication assembly 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 arranged on the oil delivery pipe 53. One end of the oil delivery pipe 53 is provided with a filter screen and enters the interior of the oil tank 51 through the oil outlet, so as to send the lubricating oil liquid in the oil tank 51 to the other end of the oil delivery pipe 53 through the oil pump 52. At least one oil dripping port is provided at the other end of the oil delivery pipe 53. The oil dripping port corresponds to the turntable driving mechanism 4 and is located above it, for dripping the lubricating oil liquid onto the turntable driving mechanism 4.

[0105] In some embodiments, two oil dripping ports are arranged on the oil delivery pipe 53, respectively located above the side surfaces of the notched disc 62 and the pin 63, for dripping oil onto the side surfaces of the notched disc 62 and the pin 63. During the contact process of the notched disc 62 and the pin 63 with the driven sprocket wheel respectively, the lubricating oil liquid will be transferred to the driven sprocket wheel, thus realizing the lubrication of the entire turntable driving mechanism 4.

[0106] Optionally, the pipe section of the oil delivery pipe 53 provided with the oil dripping port can be set as a copper pipe 54, so as to improve the stability of this pipe section and ensure that the lubricating oil liquid dripping from the oil dripping port can drip to the predetermined position.

[0107] In some embodiments, in order to facilitate the collection and recycling of lubricating oil, a first oil collecting tray 71 is provided below the driving dial 61, the notched disc 62 and the pin 63. The first oil collecting tray 71 is provided with an oil return port 711, and the oil return port 711 is connected to the oil inlet through an oil return pipe to collect the lubricating oil in the first oil collecting tray 71.

[0108] Furthermore, since the driven sprocket will come into contact with lubricating oil during the contact process with the notched disc 62 and the pin 63, in order to facilitate the collection of the lubricating oil on all the driven sprockets, an arc-shaped second oil collecting tray 72 is provided vertically below the driven sprocket. Both ends of the second oil collecting tray 72 are provided with notches, and the notches at both ends are located above the first oil collecting tray 71, so that the lubricating oil in the second oil collecting tray 72 can flow into the first oil collecting tray 71, and through the connection between the first oil collecting tray 71 and the fuel tank 51, the recovery and recycling of the lubricating oil are completed.

[0109] Participate Figure 12 、 Figure 14 and Figure 15 As shown in and in some embodiments, the base 8 is equidistantly provided with a plurality of support assemblies 81. The support assembly 81 includes a support base 811, a support member 812, a screw 813, a nut 814, a gasket 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 with a wear-resistant plate 817. The flexible pad 816 and the gasket 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 in threaded cooperation with the support base 811. By the insertion length of the screw 813 relative to the support base 811, the gasket 815, the flexible pad 816 and the support member 812 can be sequentially pushed to move, so as to adjust the overall height of each support assembly 81, and further adapt to different assembly environments to ensure that the wear-resistant plate 817 of each support assembly 81 can stably contact the turntable base. The nut 814 is sleeved on the screw 813 and is located outside the support base 811, so as to prevent the screw 813 from moving.

[0110] Optionally, the flexible pad 816 can be made of rubber material, so that after the screw 813 is adjusted, a slight height difference can be made through the flexible pad 816 for adaptive adjustment.

[0111] Optionally, a convex block 8171 is provided on one side of the wear-resistant plate 817 facing the support member 812, and a groove 8121 matching the convex block 8171 is provided at one end of the support member 812 for installing the convex block 8171. By assembling the convex block 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.

[0112] In addition, since the turntable base is heavy, it will generate friction with the wear-resistant plate 817. During the long-term friction process, due to the heat generated by the wear-resistant plate 817 and the turntable base, problems such as accelerated damage to the surfaces of the wear-resistant plate 817 and the turntable base and increased friction will occur, affecting the normal use of the turntable base.

[0113] To solve the above problems, the wear-resistant plate 817 is made of pig iron, and the part of the turntable base that contacts the wear-resistant plate 817 is made of wrought iron. The hardness of pig iron is greater than that of wrought iron, which can greatly alleviate the problem of increased friction caused by wear.

[0114] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
