[0024] Through the action of hydraulic push rod 4, can drive upper mould 5 to descend, make it with the connecting mould 6 installed at the top of lower mould 2 accurate butt joint, to realize the die casting forming of oil cylinder pump body. After die casting, hydraulic push rod 4 drives upper mould 5 to rise, at this time, core pulling mechanism 7 executes core pulling operation, and ejection mechanism 10 is responsible for the oil cylinder pump body from the mould after forming and ejecting. In view of the specific structure of core pulling mechanism 7 and ejection mechanism 10 belongs to the prior art that the person skilled in the art is familiar with, hereinafter is not described in detail.

[0025] In addition, the driving structure 13 makes the height of the mainboard 1 can be adjusted according to the height of the operator, this characteristic improves the convenience and adaptability of the equipment use, enhances the overall practicability.

[0026] The driving structure 13 comprises a motor 1301 mounted on the inner bottom wall of the support box 12, the output end of the motor 1301 is fixedly connected with a screw rod 1302, the outer wall of the screw rod 1302 is threadedly connected with a moving plate 1303, both ends of the moving plate 1303 are slidably connected with limiting columns 1304, both sides of the top end of the moving plate 1303 are fixedly connected with connecting blocks 1305, the top ends of the two connecting blocks 1305 penetrate through the support box 12 and are fixedly connected with the main plate 1, the other end of the connecting mold 6 is provided with a connecting piece 18, the top end of the screw rod 1302 is fixedly connected with a rotating shaft 14, both ends of the limiting column 1304 are fixedly connected with the support box 12, both sides of the top end of the support box 12 are provided with moving grooves 15 matched with the connecting blocks 1305, the top end of the connecting mold 6 is provided with a lower mold groove 17 for mounting the lower mold 11, the bottom ends of the two support boxes 12 are fixedly connected with friction increasing plates 16, the rotating shaft 14 is arranged in the support box 12 and is rotatably connected with the support box 12, the upper mold 5 is provided with a feeding pipe 8, the bottom end of the feeding pipe 8 is communicated with the lower mold 11, a plurality of mounting holes are formed in the outer walls of the upper mold 5, the lower mold 2 and the connecting mold 6.

[0027] Based on the above embodiment, the present scheme aims to achieve the following effects:

[0028] Through the synchronous action of the two motors 1301, the screw rod 1302 can be driven to rotate, and the moving plate 1303 can be lifted and lowered under the guidance of the limiting column 1304. Then the main plate 1 as a whole can be driven to move up and down through the connecting block 1305, so that the height of the main plate 1 can be adjusted according to the height of the worker, so as to adapt to different working requirements, and the practicability and operation convenience of the equipment are enhanced.

[0029] The feeding pipe 8 is used to inject the material required for the forming of the oil cylinder pump body. The design of the connecting piece 18 ensures that when the upper mold 5 is connected with the connecting mold 6 mounted on the lower mold 2, the connecting piece 18 can enter the inside of the upper mold 5, and the inclined angle design makes it can be firmly clamped with the upper mold 5, ensuring the stable connection between the upper mold 5 and the lower mold 2.

[0030] The arrangement of the rotating shaft 14 avoids the direct contact of the top end of the screw rod 1302 with the support box 12, reduces the friction that may be generated when the screw rod 1302 rotates, and significantly improves the service life of the screw rod 1302. The friction increasing plate 16 increases the friction between the support box 12 and the ground, ensuring the stability of the device. At the same time, a plurality of mounting holes are arranged on the outer walls of the lower mold 2, the upper mold 5 and the connecting mold 6, which is convenient for installing additional auxiliary mechanisms, and further improves the practicability of the equipment.

[0031] The working process of the device when in use is as follows:

[0032] 1. Die casting process: The action of the hydraulic push rod 4 can drive the upper mold 5 to descend, so that it can be precisely connected with the connecting mold 6 installed at the top of the lower mold 2, thereby realizing the die casting of the oil cylinder pump body.

[0033] 2. Ejection Process: After die casting is completed, the hydraulic push rod 4 drives the upper mold 5 to rise. At this time, the core-pulling mechanism 7 performs the core-pulling operation, while the ejection mechanism 10 is responsible for ejecting the formed hydraulic cylinder pump body from the mold. The two mechanisms work together to ensure smooth demolding of the finished product.

[0034] 3. Height Adjustment: Furthermore, the synchronized operation of the two motors 1301 drives the screw 1302 to rotate, causing the moving plate 1303 to move up and down under the guidance of the limit post 1304. This, in turn, drives the main board 1 to move up and down via the connecting block 1305, allowing the height of the main board 1 to be adjusted according to the operator's height, ensuring adaptability to different work needs and improving the practicality and ease of operation of the equipment.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way.
