Technical Field

[0001] The utility model relates to the technical field of water pump casing production, in particular to a water pump casing casting mould. Background Art

[0002] A water pump is a device used to transport liquid or increase liquid pressure. It mainly transfers the mechanical energy of the prime mover or other external force to the liquid to increase the liquid energy, thereby meeting the water supply or pressure requirements. With the rapid development of industrial technology, water pumps, as an important fluid transportation equipment, have been widely used in various fields. In the production and processing of water pumps, the casting material is usually injected into the mold through a casting process, and the water pump housing is formed after the material is cooled and solidified. There are some problems with traditional water pump housing casting molds. For example, traditional molds are easily affected by gravity during the casting process to produce internal hollowing, resulting in the inability to quickly discharge air inside. This not only affects the structural strength of the shell, but also reduces the accuracy and yield of casting. Therefore, it is necessary to design a water pump housing casting mold.

The movable rod 70 1 is provided with a slide groove on the inner side, so that the slide pile 703 can slide along the slide groove; the movable rod 701 is movably connected to the base 3 through the shaft frame 702, and the movable rod 701 can be turned over through the shaft frame 702. When the lower mold 2 is pushed to turn and stand up by the driving rod 302, the slide pile 703 can slide along the slide groove on the movable rod 701; when the slide pile 703 slides to the end of the slide groove, the slide pile 703 is limited by the slide groove, so that the upper mold 1 can be pulled to turn and open, so that the upper mold 1 can be in an upright state, so that the staff can conveniently perform demoulding operations and clean up the debris remaining in the upper mold 1 and the lower mold 2, thereby improving the maintenance work efficiency.

[0025] The working principle of the water pump housing casting mold based on the embodiment is: by combining the upper mold 1 and the lower mold 2, the casting material of the water pump housing is introduced from the casting port at the top of the upper mold 1, so that the casting material flows into the lower mold 2 for molding operation. During the casting process, by starting the motor 5, the belt 501 is used to drive the rotating rod 801 to rotate, and the striking head 806 can be driven to rotate synchronously. When the striking head 806 rotates and strikes the block 802, the striking head 806 can strike the striking block 802. The impact force is generated, and the impact block 802 squeezes the impact head 806, so that the sliding frame 804 can slide along the limit seat 803, so that the impact head 806 can be displaced, and the impact head 806 can smoothly pass the position of the impact block 802. By continuously hitting the impact block 802, the lower mold 2 can be vibrated, and the vibration wave is transmitted to the upper mold 1. The impact force generated can vibrate the liquid casting material inside the mold, so that the liquid casting material can flow, which can The bubbles or air attached to the inner wall of the upper mold 1 and the lower mold 2 are pushed to the center or top of the liquid material, so that the air can be quickly discharged, avoiding the hollow phenomenon inside, and improving the production quality of the water pump housing. After the casting is completed, the lower mold 2 can be pushed to flip upward by the extension and contraction of the driving rod 302, so that the lower mold 2 can be flipped around the axis of the movable seat 4, so that the lower mold 2 can be erected in a vertical state. When the lower mold 2 is flipped, the sliding pile 703 can slide along the slide groove on the movable rod 701. When the sliding pile 703 slides to the end of the slide groove, the upper mold 1 can be flipped open by the limiting effect of the movable rod 701 on the sliding pile 703, and the upper mold 1 can be erected in a vertical state, so that the staff can easily demould the water pump housing formed inside the mold. At the same time, the staff can easily clean the debris remaining inside the upper mold 1 and the lower mold 2 during maintenance, and the debris that can be cleaned can be conveniently exported, effectively improving the maintenance efficiency.
