[0019] In order to describe the technical content, structural features, achieved purpose and effect of the utility model in detail, the technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described are only a part of the embodiments of the present application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the utility model. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0020] See also Figure 1 As shown, the embodiments of this application provide a mold clamping power pack with an integrated design for use in plastic molding equipment to provide power for the mold clamping mechanism. The pack comprises a housing 1, an oil tank 6 integrally disposed within the housing 1, a motor 3 mounted above the oil tank 6, and a gear pump 2 drivingly connected to the motor 3. The gear pump 2 is located within the oil tank 6, with its oil intake submerged in the oil.

[0021] The mold-locking power pack of this application is suitable for use in all-electric blow molding machines. During the mold-locking process, the motor of an all-electric blow molding machine requires full torque output. The motor in this application is vertically mounted, and the gear pump is buried in the oil tank. This not only saves space but also achieves the mold-locking effect with minimal energy consumption. In this embodiment, the motor is a servo motor, and the gear pump is an internal gear pump.

[0022] In one embodiment, the housing 1 includes a pair of side panels 16, a heat sink 13 connecting the side panels 16, and a rear panel. The heat sink 13 is provided with a plurality of heat dissipation holes. The bottoms of the side panels 16 are folded outward to form hems. The hems on the side panels allow the clamping power pack to be securely mounted on the frame of the plastic molding equipment. The fuel tank includes a top panel, a bottom panel, and a front panel. These top, bottom, and front panels are welded to the pair of side panels and the rear panel, forming an integral part of the housing. To ensure a clear view of the liquid level in the fuel tank 6, the housing 1 is also provided with a liquid level gauge 12 connected to the fuel tank 6.

[0023] In one embodiment, to cool the oil in the tank, the oil tank 6 is located at the bottom of the housing 1, and an inserted oil cooler 7 is installed at the front end of the oil tank 6. The inserted oil cooler 7 has an oil inlet and an oil outlet, wherein the oil inlet is located in the oil tank 6 and communicates with the oil outlet of the gear pump 2.

[0024] In one embodiment, the oil outlet of the plug-in oil cooler 7 is communicated with the main valve block 10 through the filter 8 , and the main valve block 10 has an oil outlet port 15 connected to the load pipeline.

[0025] In one embodiment, a pressure sensor 9 and a relief valve 11 are installed on the main valve block 10 , and the relief valve 11 is connected to the oil tank 6 through a return pipe 14 .

[0026] A pair of side panels 16, the heat sink 13, the rear panel, and the upper and front surfaces of the oil tank 6 collectively form a storage space, within which the motor 3, the plug-in oil cooler 7, the filter 7, the main valve block 10, and the return pipe 14 are all housed, forming a single unit. The oil tank of the present application is integrally formed on the housing, with the motor located above the oil tank, and the main valve block, filter, and plug-in oil cooler located in the storage space in front of or above the oil tank. Therefore, the present invention has a compact, modular structure, allowing for flexible and reasonable positioning.

[0027] In one embodiment, the motor and gear pump are connected via a coupling, which is also submerged in the oil tank. A bell-shaped housing surrounds the coupling. This protects the coupling from foreign matter and keeps it clean, extending the service life of the coupling and the entire transmission system. Furthermore, in the event of a coupling failure, the bell-shaped housing prevents coupling components from flying out, potentially harming nearby personnel and equipment, thus providing a safety barrier.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes.
