[0029] Referring to the drawings, the driving device of the plastic product turnover mold in the embodiment of the present embodiment comprises a driving motor 1 and a speed reducer 2. The driving motor 1 comprises a driving shaft 10 and a motor shell 11, and the speed reducer 2 comprises a transmission shaft 20 and a speed reducer shell 21. The driving shaft 10 and the transmission shaft 20 are connected through a shaft coupling 3. The driving shaft 10 of the driving motor 1 can drive the transmission shaft 20 of the speed reducer 2 to rotate through the shaft coupling 3, and the power output is matched to drive the plastic product turnover mold to run.

[0030] The coupling seat 4 is connected and installed between the motor shell 11 of the driving motor 1 and the reduction shell 21 of the speed reducer 2, and the coupling seat 4 can also be used to improve the stability of the driving operation. The coupling seat 4 includes a seat body 40, and the seat body 40 is provided with a front-rear through connection channel 41. The connection channel 41 includes a section position for the operation of the coupling shaft 3, and the coupling shaft 3 can rotate in the section position. The driving shaft 10 and the transmission shaft 20 can be connected through the coupling shaft 3. The motor shell 11 is connected to the front side of the seat body 40, and the reduction shell 21 is connected to the rear side of the seat body 40. In addition, the seat body 40 of the coupling seat 4 is provided with a water inlet 401, and the seat body 40 is provided with a water cooling channel 402. The water inlet 401 is connected to the water cooling channel 402, so that the cooling liquid can be connected to the water cooling channel 402 through the water inlet 401. The seat body 40 has a cooling function, which can cool the heat generated during the operation of the coupling shaft 3, improve the operation stability of the coupling shaft 3, and even cool the rear side of the driving motor 1 to a certain extent. The operation stability of the entire driving device can be improved, the driving motor 1 can still operate normally after being speeded up, the service life of the driving motor 1 can be relatively prolonged after being cooled, the use cost is low, and the driving motor 1 with relatively high cost and relatively good performance can meet the operation stability and speed-up requirements.

[0031] The driving device of the plastic product turnover mold adopts the coupling seat 4 with cooling function, which can not only connect and install the driving motor 1 and the speed reducer 2, but also cool the coupling shaft 3 and the like, improve the operation stability of the entire driving device (and the driving motor 1), ensure that the driving motor 1 can still operate normally after being speeded up, prolong the service life of the driving motor 1 after being cooled, reduce the use cost, and meet the operation stability and speed-up requirements without configuring the driving motor 1 with relatively high cost and relatively good performance.

[0036] In addition, the seat body 40 has a boss 403 inwardly protruding at the section position of the connecting channel 41, that is, the boss 403 protrudes towards the center line axis in the radial direction, so that the connecting channel 41 is narrowed at the section position. The boss 403 has a through hole 4031, and the coupling 3 is located at the through hole 4031. The coupling 3 can operate at the through hole 4031. The cooling channel is located at the boss 403, and the coupling can be cooled and cooled better. The front and back sides of the boss 403 are cavities, so that the seat body 40 still has sufficient space for installation and heat dissipation. There is a gap between the through hole 4031 and the coupling 3 to avoid mutual contact and interference with the normal operation of the coupling 3.

[0037] In addition, the front port 412 of the connecting channel 41 is located on the front side of the seat body 40, and the rear port 411 of the connecting channel 41 is located on the rear side of the seat body 40.

When the reducer 2 (including the reduction shell 21) is installed, the coupling seat 4 is accurately and quickly matched and positioned.

[0038] The rear end surface of the motor shell 11 is also connected to install a support plate 12 (which can be made of stainless steel or iron plate, etc., which can stably support the motor operation), the front end surface of the seat body 40 is matched with the rear side wall of the support plate 12 and is in close contact (such as a stable matching mode of flat surface and flat surface close to each other), and the rear side wall of the support plate 12 is also provided with a positioning rear protrusion 121, which is positioned and sleeved with the front port 412 of the connecting channel 41, so as to facilitate accurate and rapid matching and positioning when the driving motor 1 (including the motor shell 11) is installed with the connecting seat 4.
