In order to adapt to faster, more stable and more precise operation, the motor will overheat. Currently, a fan can be added to the tail end of the motor for heat dissipation. However, this heat dissipation method is not very effective and cannot efficiently dissipate heat from the entire motor body, affecting the motor performance and operation. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a drive device for a plastic product thermoforming machine that is optional and has a high heat dissipation and cooling effect.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a driving device for a plastic product thermoforming machine, including a driving motor, the driving motor including a housing, characterized in that: heat dissipation plates are respectively arranged on the left and right outer sides of the housing, the heat dissipation plates are connected to each other by connecting rods, the connecting rods are respectively located on the upper and lower outer sides of the housing, the heat dissipation plates are sandwiched on the left and right outer sides of the housing, a water cooling channel is provided inside the heat dissipation plate, and a water inlet is also provided on the heat dissipation plate, the water inlet being connected to the water cooling channel.

[0005] The following optimizations or supplementary explanations can be made to the above technical solutions.

[0006] For example, the surface of the heat sink is fitted to match the outer contour of the casing.

[0007] For example, the heat sink has mounting holes, and the end of the connecting rod has a connection hole. The mounting holes and the connection holes correspond to each other and are connected by fasteners.

[0008] In addition, the left and right heat sinks are connected to each other by a water-passing shaft. The water-passing shaft has a water-passing channel. One end of the water-passing channel of the water-passing shaft is connected to the water-cooling channel in the left heat sink, and the other end of the water-passing channel of the water-passing shaft is connected to the water-cooling channel in the right heat sink.

[0009] For example, the water cooling channel includes a water inlet hole, which is located on the inside of the heat sink. The water inlet shaft is a hollow shaft, with the hollow middle section serving as the water inlet channel. The end of the water inlet shaft is connected to the water inlet hole.

[0010] Further optimization involves the water-passing shaft having a limiting step ring at its end that engages with the water-passing connection hole of the heat sink, and an annular groove at its end containing a sealing ring.

[0011] For example, the water cooling channel includes horizontal holes and vertical holes, with the horizontal holes connected to the vertical holes.

[0012] For example, the transverse holes and longitudinal holes are drilled, the ends of the drilled holes are equipped with plugs, and the water inlets are equipped with water nozzles.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Referring to the accompanying drawings, the driving device of the plastic product thermoforming machine in this embodiment, such as the driving structure of the flipping mold, includes a drive motor 1. The drive motor 1 includes a housing 10 (i.e., motor housing 10). Heat sinks 2 are respectively arranged on the left and right outer sides of the housing 10. The heat sinks 2 can be made of materials with good heat dissipation, such as aluminum or copper. The heat sinks 2 (left and right sides) are connected to each other by connecting rods 3. The connecting rods 3 are located on the upper and lower outer sides of the housing 10, and the heat sinks 2 are clamped on the left and right outer sides of the housing 10. In this structure, the connecting rods 3 cooperate to install and clamp the heat sinks 2 on the left and right sides of the housing 10 for cooperation and connection. The structure is relatively simple and compact, and is not likely to affect or interfere with other structures of the plastic product thermoforming machine (including the driving device itself). The structure is also relatively stable. A water cooling channel 21 is provided inside the heat sink 2, and a water inlet 22 is also provided on the heat sink 2. The water inlet 22 is connected to the water cooling channel 21, and the liquid used for water cooling is input and output through the water inlet 22.

[0027] In the drive unit of this plastic product thermoforming machine, the heat sink 2 is sandwiched between the left and right sides of the housing 10 of the drive motor 1. The structural layout is relatively reasonable and does not affect the position of the front and rear ends of the drive motor 1. Furthermore, the assembly is relatively convenient and will not affect the structure of the drive motor 1 itself. It can be added to the drive unit that has already been shipped, making it more practical. Through the combination of the heat sink 2 and water cooling, the heat dissipation is relatively good and can cool the corresponding area of ​​the main body (i.e., housing 10) of the drive motor 1.

[0028] Based on the above embodiments, the following optimizations or further explanations can be made.

[0029] For example, the surface 27 of the heat sink 2 is matched and abutted against the outer contour of the housing 10. For example, the concave and convex contours 26 of the outer contour of the housing 10 (i.e. the left and right outer sides) match the concave and convex contours of the surface 27 of the heat sink 2. The heat sink 2 and the housing 10 are abutted against each other, and the heat transfer and conduction effects are better, resulting in better heat dissipation and cooling effects.

[0030] For example, the heat sink 2 has mounting holes 23, and the end of the connecting rod 3 has a connecting hole 31. The mounting holes 23 and the connecting holes 31 correspond to each other and are connected by fasteners 32, making installation relatively convenient and facilitating the heat sink 2 to clamp the housing 10. For example, the connecting hole 31 can be a threaded hole, the mounting hole 23 can be a stepped hole, and the fastener 32 can be a screw (such as an internal hex screw). Of course, other fastener 32 installation and connection methods can also be used.

[0031] The water-cooling channels 21 in the heat sinks 2 on the left and right sides can be independent of each other or connected to each other. For example, by using an interconnected method, the left and right heat sinks 2 are also connected to each other by a water-passing shaft 4. The water-passing shaft 4 has a water-passing channel 40. One end of the water-passing channel 40 of the water-passing shaft 4 is connected to the water-cooling channel 21 in the left heat sink 2, and the other end of the water-passing channel 40 of the water-passing shaft 4 is connected to the water-cooling channel 21 in the right heat sink 2. Connecting the water-cooling channels 21 in the left and right heat sinks 2 simplifies the input and output of the water-cooled liquid between the two heat sinks 2. For example, the water inlet 22 is divided into an inlet and an outlet. The inlet is configured on one heat sink 2 (such as the left heat sink 2), and the outlet is configured on the other heat sink 2 (such as the right heat sink 2). The water-cooled liquid is input from the inlet (inlet) into the water-cooling channel 21 of one heat sink 2 and flows through the water-passing shaft 4 into the water-cooling channel 21 of the other heat sink 2. The water-cooled liquid is finally output from the outlet (outlet). Of course, water inlets and outlets can also be installed on each heat sink 2 to connect to external water pipes.

[0032] When the water-passing shaft 4 is installed, the water-cooling channel 21 includes a water-passing connection hole 211, which is located on the inner side of the heat sink 2. The water-passing shaft 4 is a hollow shaft (or hollow shaft), and the hollow part in the middle of the hollow shaft is the water-passing channel 40. The end of the water-passing shaft 4 (i.e., the shaft end) is connected to the water-passing connection hole 211. That is, the water-passing connection hole 211 is provided on the inner side of the left and right heat sinks facing each other for installing and connecting the water-passing shaft 4 (which is connected to the water-passing channel 40 in the middle). The water-passing shaft 4 can be connected to the water-passing connection hole 211 by using a plug-in sleeve. The connection can be made in various ways, such as by means of threaded connection or by other means. For example, the end of the water-passing shaft 4 also has a limiting step ring 41, which is matched with the water-passing connection hole 211 of the heat sink 2. The end of the water-passing shaft 4 can be inserted into the water-passing connection hole 211 of the heat sink 2. The limiting step ring 41 can be used to limit the insertion. The end of the water-passing shaft 4 is also provided with an annular groove 42, in which a sealing ring 43 is provided to prevent water-cooling liquid from leaking between the end of the water-passing shaft 4 and the water-passing connection hole 211. This insertion connection structure is relatively easy to install.

[0033] In addition, the water cooling channel 21 includes a transverse hole 212 and a longitudinal hole 213. The transverse hole 212 and the longitudinal hole 213 are connected, and the structure is relatively precise. The transverse hole 212 and the longitudinal hole 213 are drilled, and the drilling structure is relatively simple to process. According to the requirements, the corresponding transverse holes 212 and longitudinal holes 213 (or vertical holes) can be arranged horizontally and vertically, and the connection is relatively convenient. The end of the drilled hole (i.e., the port 214 of the transverse hole 212 and the longitudinal hole 213) can be equipped with a plug to form a water cooling channel 21 in the heat sink 2, and to seal the port formed on the heat sink 2 by the drill bit. The port at the end of one of the drilled holes can be used as a water inlet 22. In the path connecting the transverse hole 212 and the longitudinal hole 213, corresponding partition holes 24 can be fabricated on the heat sink 2 by drilling (e.g., with a drill bit). Partition plugs 25 are then inserted into the partition holes 24 to partition the path of the water cooling channel 21 as needed. This allows the water cooling channel 21 to follow the required path, such as forming a serpentine (S-shaped) path, resulting in more efficient cooling, better water cooling effect, and a more rational cooling liquid path. Furthermore, the water inlet 22 is equipped with a water spout 221 for easy connection to external water pipes, allowing external water sources to be accessed for water circulation.
