Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, and in particular to a turntable device and shoemaking equipment for injection molding shoemaking. 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. Furthermore, the length and diameter of the cooling water pipes in the shoe mold are limited by the overall size of the mold and cannot be made too large. Therefore, the amount of cooling water provided and the cooling area are relatively small, resulting in limited actual accelerated cooling effect and a not significant improvement in sole molding efficiency. Utility Model Content

[0003] In order to overcome at least one of the defects of the prior art, the present invention provides a turntable device and shoe-making equipment for injection molding shoes, which can solve the problem that the efficiency of sole forming is not significantly improved by cooling the left and right shoe molds.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0008] The left shoe mold, the right shoe mold, and the bottom mold are all mounted on the cooling plate, and the bottom mold is in contact with the cooling plate. The cooling plate has a second liquid cooling channel in a tortuous shape.

[0009] Furthermore, the left shoe mold, the right shoe mold, and the bottom mold are all attached to the cooling plate.

[0010] Furthermore, both the left shoe mold and the right shoe mold are provided with a first liquid cooling channel, and the first liquid cooling channel in the left shoe mold is connected to the first liquid cooling channel in the right shoe mold.

[0011] Furthermore, the turntable assembly includes a turntable base, the turntable base is provided with a cooling plate assembly slot, and the cooling plate is embedded in the cooling plate assembly slot.

[0012] Furthermore, the second liquid cooling channel has an inlet and an outlet, which are located at opposite ends of the second liquid cooling channel.

[0013] Furthermore, the turntable base is provided with a first pipe groove at the position of the cooling plate assembly groove corresponding to the water inlet. 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 water outlet pipe near the cooling plate is embedded in the first pipe groove for installation.

[0014] The turntable base is provided with 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 water supply pipe near the cooling plate can be embedded in the second pipe groove for installation.

[0015] Furthermore, the turntable base is provided with a plurality of cooling plate mounting slots, and all the cooling plate mounting slots are evenly distributed along the circumference of the turntable base;

[0016] N adjacent cooling plate assembly slots form a group. The turntable base is provided with a first pipe groove at the cooling plate assembly slot located on one side of each group of cooling plate assembly slots, and the first pipe groove corresponds to the water inlet of the cooling plate installed in the cooling plate assembly slot.

[0017] The turntable base is provided with a second pipe groove at the cooling plate assembly groove on the other side of each group of cooling plate assembly grooves, and the second pipe groove corresponds to the water outlet of the cooling plate installed in the cooling plate assembly groove.

[0018] In each set of cooling plate assembly slots, a third pipe groove is provided 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 is embedded in the turntable base for installation.

[0019] Furthermore, the cooling plate assembly groove extends through the turntable base, and a limiting member for supporting the cooling plate is provided on the side of the cooling plate assembly groove away from the contact surface between the cooling plate and the shoe mold assembly.

[0020] Furthermore, the limiting component is a limiting plate, which is located on the side of the cooling plate assembly groove away from the contact surface between the cooling plate and the shoe mold assembly;

[0021] Alternatively, the limiting element may be a plurality of limiting protrusions extending into the sidewall of the cooling plate mounting slot.

[0027] In summary, the turntable device and shoe-making equipment for injection molding shoes provided by this utility model have the following technical effects:

[0028] 1. Both the left and right shoe molds are equipped with a first liquid cooling pipeline, which can efficiently remove the heat conducted by the injection molding liquid during the injection molding process, quickly reduce the temperature of the shoe molds themselves, and effectively reduce product defects caused by high temperature.

[0029] 2. The cooling plate is equipped with a second liquid cooling channel to cool the cooling plate, thereby cooling the bottom mold placed on the cooling plate. Compared with the left and right shoe molds, the bottom mold has a larger contact area with the liquid material to be formed, and a larger contact area with the cooling plate, which greatly improves the cooling effect. At the same time, the left and right shoe molds are also placed on the cooling plate, and the cooling plate cools the left and right shoe molds simultaneously, thereby achieving multi-directional cooling, which improves the forming speed of the shoe sole, ensures the quality of the formed product, and avoids problems that may be caused by local temperature differences.

[0030] 3. Because the left shoe mold, right shoe mold, and sole mold are in contact with the cooling plate, even if there is a large difference in the cooling effect of the first liquid cooling channel and the second liquid cooling channel, the temperature dynamic balance among the left shoe mold, right shoe mold, sole mold, and cooling plate can be achieved through the heat conduction of the contact between the left shoe mold and the cooling plate, thereby improving the overall quality and consistency of the processed shoe sole.

[0031] 4. The second liquid cooling channel is arranged in a tortuous manner inside the cooling plate, which can ensure the duration of heat exchange between the coolant flowing in the second liquid cooling channel and the cooling plate, thereby ensuring the cooling effect of the cooling plate.

[0032] 5. The inlet and outlet of the second liquid cooling channel are located at both ends of the second liquid cooling channel, which facilitates the assembly of external water supply pipes and external water outlet pipes. Attached Figure Description

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] See Figures 1-11This utility model discloses a turntable device for injection molding shoes, including a turntable assembly. The turntable assembly is provided with a cooling plate 2 and a shoe mold assembly 3. The shoe mold assembly 3 has a left shoe mold 31, a right shoe mold 32 and a bottom mold 33. The bottom mold 33 is located between the left shoe mold 31 and the right shoe mold 32. The left shoe mold 31 and / or the right shoe mold 32 are provided with a first liquid cooling channel 34. The left shoe mold 31, the right shoe mold 32 and the bottom mold 33 are all located on the cooling plate 2 and are in contact with the cooling plate 2. The cooling plate 2 is provided with a second liquid cooling channel 21.

[0055] Specifically, the turntable assembly includes a cooling plate 2 and a shoe mold assembly 3. The shoe mold assembly 3 comprises a left shoe mold 31, a right shoe mold 32, and a bottom mold 33. The bottom mold 33 is located between the left shoe mold 31 and the right shoe mold 32 and is used for forming the bottom surface of the shoe sole. The left shoe mold 31 and the right shoe mold 32 are used for forming the outline and side profile of the shoe sole. During use, a shoe last is inserted between the left shoe mold 31 and the right shoe mold 32, thus forming a cavity for sole forming between the shoe last, the left shoe mold 31, the right shoe mold 32, and the bottom mold 33. Of course, for soles that can be formed using the left shoe mold 31, the right shoe mold 32, and the bottom mold 33, a shoe last is not required. The turntable assembly mainly drives the shoe mold assembly 3, which is located above the turntable assembly, to rotate, thereby enabling the injection molding of multiple shoe mold assemblies 3 that may be located on the turntable assembly.

[0056] See Figures 1-6 As shown, the left shoe mold 31 and the right shoe mold 32 can be configured with either a first liquid cooling channel 34 in the left shoe mold 31, a first liquid cooling channel 34 in the right shoe mold 32, or both in both shoe molds 31 and 32, depending on requirements. No specific limitation is made here; the following examples will use the scenario where both shoe molds 31 and 32 have a first liquid cooling channel 34. The first liquid cooling channels 34 in the left shoe mold 31 and the right shoe mold 32 can be connected in series or in parallel. The specific method of guiding the coolant can be freely selected according to requirements. Cooling plate 2 is mounted on the turntable assembly to rotate with the turntable assembly. Cooling plate 2 has a second liquid cooling channel 21 for cooling liquid to pass through the second liquid cooling channel 21 to cool the cooling plate 2. Left shoe mold 31, right shoe mold 32 and bottom mold 33 are all mounted on cooling plate 2. Cooling plate 2 cools the left shoe mold 31, right shoe mold 32 and bottom mold 33 that are in contact with it. Thus, while the left shoe mold 31 and right shoe mold 32 are cooled by the first liquid cooling channel 34, they are also cooled by the cooling plate 2. Correspondingly, even if there is a large difference in the cooling effect of the first liquid cooling channel 34 and the second liquid cooling channel 21, the temperature dynamic balance among the left shoe mold 31, right shoe mold 32, bottom mold 33 and cooling plate 2 can be achieved through the heat conduction of the contact between the left shoe mold 31 and right shoe mold 32 and the cooling plate 2, thereby improving the overall quality and consistency of the processed shoe sole.

[0057] Optionally, the first liquid cooling channel 34 in the left shoe mold 31 and the first liquid cooling channel 34 and the second liquid cooling channel 21 in the right shoe mold 32 can be set in series and / or in parallel, without limitation.

[0058] In addition, the second liquid cooling channel 21 is arranged in a tortuous manner within the cooling plate 2, which ensures the duration of heat exchange between the coolant flowing in the second liquid cooling channel 21 and the cooling plate 2, thereby ensuring the cooling effect of the cooling plate 2.

[0059] See Figure 2 As shown, in some embodiments, both the left shoe mold 31 and the right shoe mold 32 are provided with a first liquid cooling channel 34, and the first liquid cooling channel 34 in the left shoe mold 31 is connected to the first liquid cooling channel 34 in the right shoe mold 32.

[0060] Specifically, both the left shoe mold 31 and the right shoe mold 32 are equipped with independent first liquid cooling channels 34 for direct and rapid cooling of the shoe molds. The first liquid cooling channels 34 of the left shoe mold 31 and the right shoe mold 32 are connected. This structure allows the coolant to flow between the left shoe mold 31 and the right shoe mold 32. In other words, the first liquid cooling channels 34 of the left shoe mold 31 and the right shoe mold 32 are connected in series, which facilitates the design of the overall water supply and outlet pipes and is beneficial to the design and layout of the overall liquid cooling system.

[0061] See Figure 7 and Figure 8 As shown, in some embodiments, the turntable assembly includes a turntable base 1, the turntable base 1 is provided with a cooling plate assembly groove 11, and the cooling plate 2 is embedded in the cooling plate assembly groove 11.

[0062] Specifically, directly mounting the cooling plate 2 onto the turntable base 1 increases the overall height of the shoe mold assembly 3, consequently increasing the operator's working height and affecting ease of operation. More importantly, the shoe mold assembly 3 typically uses a left-right opening design. To ensure that the left shoe mold 31 and right shoe mold 32 do not interfere with the cooling plate 2 located at the bottom of the shoe mold assembly 3 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 1 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 the sole molding process, affecting product quality.

[0063] Correspondingly, the turntable assembly includes a turntable base 1, which has a cooling plate mounting groove 11, into which the cooling plate 2 is embedded. This greatly reduces the increase in height of the shoe mold assembly 3 due to the addition of the cooling plate 2. This structure completely avoids the problem of increased overall height of the shoe mold assembly 3 due to the addition of the cooling plate 2 in the traditional method, thus eliminating the need to set a shim under the shoe mold handle and simplifying the structure.

[0064] Furthermore, since there is no need to adjust the height of the shoe mold assembly 3 using shims, the shoe mold assembly 3 can directly and stably fit with the cooling plate 2, avoiding the problems of support rod loosening or shifting caused by traditional shims, as well as avoiding the problem of reduced mold clamping accuracy caused by raising the shoe mold handle installation position after the shoe mold assembly 3 is raised.

[0065] The cooling plate 2 is embedded in the cooling plate assembly slot 11, which means the cooling plate 2 is embedded in the turntable base 1, ensuring that the left shoe mold 31 and the right shoe mold 32 will not interfere with the cooling plate 2 or the pipeline when opening, closing or rotating. The cooling plate 2 is fixed by the cooling plate assembly slot 11, eliminating the need for additional shims or adjusting the height of the shoe mold assembly 3, thus reducing assembly complexity. At the same time, the embedded design of the cooling plate 2 facilitates quick disassembly and maintenance, reducing the extra steps required for removing shims and improving equipment maintenance efficiency.

[0066] See Figure 5 and Figure 6 As shown, in some embodiments, the second liquid cooling channel 21 has an inlet 22 and an outlet 23, with the inlet 22 and outlet 23 located at opposite ends of the second liquid cooling channel 21.

[0067] Specifically, the second liquid cooling channel 21 has an inlet 22 and an outlet 23, located at opposite ends of the channel. An external water supply pipe can be connected to the inlet 22, and an external water outlet pipe can be connected to the outlet 23, allowing external coolant to be introduced into the channel through the inlet 22. The coolant then flows out of the cooling plate 2 through the outlet 23. As the coolant flows through the channel, it carries away heat from the cooling plate 2, maintaining its low temperature and ensuring efficient cooling. The arrangement of the second liquid cooling channel 21 within the cooling plate 2 can be freely chosen as needed, as long as it effectively maintains a stable temperature. The coolant can be water or other liquids with high specific heat capacity, fast thermal conductivity, and stable chemical properties; no specific limitation is imposed.

[0068] See Figures 7-9As shown, in some embodiments, the turntable base 1 has a first pipe groove 12 at the position of the cooling plate assembly groove 11 corresponding to the water inlet 22. The groove of the first pipe groove 12 near the cooling plate 2 corresponds to the water inlet 22 of the cooling plate 2, so that the water outlet pipe near the cooling plate 2 can be embedded in the first pipe groove 12 for installation. The turntable base 1 has a second pipe groove 13 at the position of the cooling plate assembly groove 11 corresponding to the water outlet 23. The groove of the second pipe groove 13 near the cooling plate 2 corresponds to the water outlet 23 of the cooling plate 2, so that the water supply pipe near the cooling plate 2 can be embedded in the second pipe groove 13 for installation.

[0069] Specifically, since the cooling plate 2 is embedded in the cooling plate assembly groove 11, the water inlet 22 and water outlet 23 of the cooling plate 2 are generally also partially or completely located in the cooling plate assembly groove 11. This is to facilitate the connection of the water inlet 22 to the external water supply pipe and the water outlet 23 to the external water outlet pipe, and also to prevent the external water supply pipe and external water outlet pipe from interfering with the mold opening and closing movements of the shoe mold assembly 3. The turntable base 1 is provided with a first pipe groove 12 at the position of the water inlet 22 in the cooling plate assembly groove 11. That is, the turntable base 1 is provided with a first pipe groove 12 at the position corresponding to the water inlet 22 of the cooling plate 2 assembled in the cooling plate assembly groove 11. The groove of the first pipe groove 12 near the cooling plate 2 corresponds to the water inlet 22 of the cooling plate 2, so that the external water supply pipe can be connected to the corresponding water inlet 22 after being embedded in the first pipe groove 12. Similarly, the turntable base 1 is provided with a second pipe groove 13 at the position of the outlet 23 corresponding to the cooling plate assembly groove 11. That is, the processing department provides a second pipe groove 13 at the position corresponding to the outlet 23 of the cooling plate 2 assembled in the cooling plate assembly groove 11. The groove of the second pipe groove 13 near the end of the cooling plate 2 corresponds to the outlet 23 of the cooling plate 2, so that the external water outlet pipe can be inserted into the second pipe groove 13 and connected to the outlet 23.

[0070] See Figures 7-9 As shown, in some embodiments, the turntable base 1 is provided with a plurality of cooling plate assembly slots 11, and all the cooling plate assembly slots 11 are evenly distributed along the circumference of the turntable base 1.

[0071] N adjacent cooling plate assembly slots 11 form a group. The turntable base 1 has a first pipe groove 12 located on one side of the cooling plate assembly slot 11 in each group of cooling plate assembly slots 11, and the first pipe groove 12 corresponds to the water inlet 22 of the cooling plate 2 installed in the cooling plate assembly slot 11.

[0072] The turntable base 1 has a second pipe groove 13 located on the other side of the cooling plate assembly groove 11 of each group of cooling plate assembly grooves 11, and the second pipe groove 13 corresponds to the water outlet 23 of the cooling plate 2 installed in the cooling plate assembly groove 11.

[0073] In each set of cooling plate assembly slots 11, a third pipe slot 14 is provided between two adjacent cooling plate assembly slots 11. One end of the third pipe slot 14 corresponds to the water outlet 23 of the cooling plate 2 near the first pipe slot 12, and the other end corresponds to the water inlet 22 of the cooling plate 2 near the second pipe slot 13, so that the external adapter pipe connecting the two adjacent cooling plates 2 is embedded in the turntable base 1 for installation.

[0074] Specifically, when the turntable base 1 is provided with multiple cooling plate assembly slots 11, all the cooling plate assembly slots 11 are evenly distributed along the circumference of the turntable base 1 to meet the requirement that the shoe mold components 3 provided on the cooling plate assembly slots 11 are injection molded one by one during the rotation of the turntable base 1. N adjacent cooling plate assembly slots 11 are set as a group. At the cooling plate assembly slots 11 located at both ends of one group, a first pipe groove 12 is provided on one side of the cooling plate assembly slot 11, and the first pipe groove 12 corresponds to the water inlet 22 of the cooling plate 2 installed in the cooling plate assembly slot 11. A second pipe groove 13 is provided on the other side of the cooling plate assembly slot 11, and the second pipe groove 13 corresponds to the water outlet 23 of the cooling plate 2 installed in the cooling plate assembly slot 11. In addition to the cooling plate assembly slots 11 located at both ends of each set of cooling plate assembly slots 11, the cooling plates 2 in the cooling plate assembly slot 11 located between the two cooling plate assembly slots 11 can be connected in series. Specifically, the turntable base 1 is provided with a third pipe slot 14 between two adjacent cooling plate assembly slots 11. One end of the third pipe slot 14 corresponds to the water outlet 23 of the cooling plate 2 near the side of the first pipe slot 12, and the other end corresponds to the water inlet 22 of the cooling plate 2 near the side of the second pipe slot 13, so that the external adapter pipe connecting the two adjacent cooling plates 2 is embedded in the turntable base 1 for installation.

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

[0076] An external water supply pipe delivers coolant through the inlet 22 of one of the cooling plates 2 located on one side of the assembly slot 11 of each cooling plate, into the liquid cooling channel inside the cooling plate 2. After passing through the liquid cooling channel, the coolant flows through the outlet 23 of the liquid cooling plate into an external transfer pipe. From there, it enters the inlet 22 of the adjacent cooling plate 2, and so on, until the coolant cools the outlet 23 of the last cooling plate 2. Finally, it is discharged to the outside through an external outlet pipe, thus achieving the cooling effect of multiple cooling plates 2 connected in series. In various application scenarios, factors such as the type of coolant, the flow rate of the coolant, the material of the cooling plate 2, the material of the bottom mold 33 to be cooled, and the shape of the shoe sole to be formed will all affect the cooling effect when the cooling plates 2 are installed. Correspondingly, based on the fact that the cooling plate 2 can achieve the effect of indirectly cooling the sole to be formed, the specific number of cooling plates 2 connected in series through the third pipe groove 14 and the external transfer pipe can be freely selected. The specific number connected in series is not limited here. It is sufficient to complete the cooling of all the connected cooling plates 2 under the above-mentioned various influencing conditions.

[0077] See Figure 10 and Figure 11 As shown, in some embodiments, the cooling plate assembly groove 11 is provided through the turntable base 1. A limiting member 15 is provided on the side of the cooling plate assembly groove 11 away from the contact surface between the cooling plate 2 and the shoe mold assembly 3. When the cooling plate 2 is assembled in the cooling plate assembly groove 11, the cooling plate 2 abuts against the limiting member 15 to prevent the cooling plate 2 from coming out of the cooling plate assembly groove 11.

[0078] Specifically, the cooling plate assembly slot 11 is designed to penetrate the turntable base 1, providing the cooling plate 2 with a relatively large assembly space. Consequently, the volume of the cooling plate 2 can be designed to be larger, thereby improving heat conduction. A limiting member 15 is provided on the side of the cooling plate assembly slot 11 away from the contact surface between the cooling plate 2 and the shoe mold assembly 3, so that when the cooling plate 2 is assembled in the cooling plate assembly slot 11, the cooling plate 2 abuts against the limiting member 15 to prevent the cooling plate 2 from coming out of the cooling plate assembly slot 11.

[0079] See Figure 10 and Figure 11 As shown, in some embodiments, the limiting member 15 is a limiting plate, which is located on the side of the cooling plate assembly groove 11 away from the contact surface between the cooling plate 2 and the shoe mold assembly 3.

[0080] Specifically, the limiting plate is located on the side of the cooling plate assembly groove 11 away from the contact surface between the cooling plate 2 and the shoe mold assembly 3. This ensures that after the cooling plate 2 is embedded in the cooling plate assembly groove 11, it abuts against the limiting plate, preventing the cooling plate 2 from sliding out of the assembly groove, and does not interfere with the contact between the cooling plate 2 and the shoe mold assembly 3. The limiting plate structure of the limiting member 15 provides a larger contact area for the cooling plate 2, thereby improving the stability of the installation of the cooling plate 2.

[0081] Based on the structure of the limiting plate adopted by the limiting component 15, the turntable base 1 is provided with a first mounting groove 16 and a second mounting groove 17 on opposite sides of the cooling plate mounting groove 11. One end of the limiting plate is installed in the first mounting groove 16 and the other end is installed in the second mounting groove 17.

[0082] Specifically, the first mounting slot 16 is located on one side of the cooling plate assembly slot 11, and the second mounting slot 17 is located on the other side of the cooling plate assembly slot 11, opposite to the first mounting slot 16. During the assembly of the limiting plate, one end of the limiting plate is recessed into the first mounting slot 16 for fixed assembly, and the other end of the limiting plate is recessed into the second mounting slot 17 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.

[0083] 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, thus avoiding operational inconvenience or potential safety hazards caused by the protrusion of the limiting part 15.

[0084] In some embodiments, the limiting member 15 is a limiting protrusion, and multiple limiting protrusions are provided. All multiple limiting protrusions are provided in the cooling plate assembly groove 11 to support the cooling plate 2.

[0085] Specifically, all the limiting protrusions are provided on the groove wall of the cooling plate assembly groove 11 so that when the cooling plate 2 is embedded in the cooling plate assembly groove 11, the cooling plate 2 abuts against the limiting protrusions, thereby supporting the cooling plate 2. Correspondingly, in order to improve the uniform support of the limiting protrusions on the cooling plate 2, the limiting protrusions can be set at equal intervals. Preferably, when the cooling plate assembly groove 11 is rectangular, a limiting protrusion can be provided in the middle of each of the four side walls of the cooling plate assembly groove 11, thereby achieving uniform support for the cooling plate 2 and avoiding deformation or damage caused by uneven local stress.

[0086] See Figure 1 and Figure 3 As shown, in some embodiments, the cooling plate 2 is flush with the surface of the turntable base 1 for contacting the cooling surface of the shoe mold assembly 3.

[0087] Specifically, the cooling surface of the cooling plate 2, which contacts the shoe mold assembly 3, is flush with the surface of the turntable base 1. That is, the upper surface of the cooling plate 2 is flush with the upper surface of the turntable base 1, thus providing a flat assembly platform. This allows the shoe mold assembly 3 to be placed stably and accurately on the cooling plate 2, reducing assembly difficulties caused by unevenness. Of course, the flat assembly platform provided by the cooling plate 2 and the turntable base 1 also facilitates the assembly of other components.

[0088] Reference Figure 12 As shown, this utility model also provides a shoe-making device, including a drive mechanism 4 and the above-mentioned turntable device for injection molding shoes. The turntable base 1 is connected to the drive mechanism 4 in a transmission manner so that the drive mechanism 4 drives the turntable base 1 to rotate.

[0089] Specifically, as an option, the drive mechanism 4 can be a motor, with a reducer connected to the motor drive, and the motor is connected to the turntable device through the reducer. Of course, the drive mechanism 4 can also be a poled drive mechanism. Correspondingly, the turntable base 1 can also be driven by the poled drive mechanism to drive the turntable base 1 located on the rotating shaft base, thereby driving the turntable base 1 to rotate around the rotating shaft base at a fixed rotation angle.

[0090] In some embodiments, the turntable drive mechanism includes a plurality of driven pulleys fixed to the bottom of the turntable base 1, 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 1.

[0091] 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 2 is also the same as the first distance. This ensures that when the driven grooved wheel rotates a distance of the first distance, the external shoe sole mold assembly moves a 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 corresponding to the opening of the injection head.

[0092] Since the turntable drive mechanism is existing technology, it will not be described in detail here. For details, please refer to patent CN212241855U.

[0093] See Figure 13 and Figure 14As 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.

[0094] 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.

[0095] Optionally, the section of the oil pipeline 53 with the drip nozzle can be fitted with a copper pipe 54 to improve the stability of the section and ensure that the lubricating oil dripping from the drip nozzle can reach the predetermined position.

[0096] 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.

[0097] 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.

[0098] participate Figure 13 , Figure 15 and Figure 16As 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 to adapt to different assembly environments and ensure that the wear-resistant plate 817 of each support component 81 can be stably contacted with the turntable base 1. Nut 814 is fitted onto screw 813 and located outside support 811, thereby preventing screw 813 from moving.

[0099] 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.

[0100] 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.

[0101] In addition, because the turntable base 1 is relatively heavy, 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 1 will accelerate the damage to the surfaces of the wear-resistant plate 817 and the turntable base 1, increase friction, and affect the normal use of the turntable base 1.

[0102] To solve the above problems, the wear-resistant plate 817 is made of cast iron, and the part of the turntable base 1 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.

[0103] 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.
