After cooling, it is molded and removed from the mold. However, when producing oil distribution plates of different sizes, molds of different specifications need to be replaced to meet production needs. At present, the molds are mostly installed with screws and nuts, and disassembly requires the help of additional auxiliary tools, which is more troublesome. Secondly, demolding after cooling is more troublesome, and electric demolding is more expensive. Therefore, a casting equipment for a multi-cavity oil distribution plate is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3, the utility model provides an embodiment: a casting device of a multi-cavity oil distribution plate, including a base 1, the outer wall of the base 1 is fixedly connected to a lower mold base 2, the inner wall of the lower mold base 2 is fixedly connected to a guide rod 3, the top of the guide rod 3 is fixedly connected to a top plate 4, the top of the top plate 4 is fixedly connected to a hydraulic cylinder 5, a hydraulic rod 6 is arranged inside the hydraulic cylinder 5, the bottom end of the hydraulic rod 6 is fixedly connected to an upper mold base 7, the inner wall of the upper mold base 7 is slidably connected to the outer wall of the guide rod 3, the hydraulic cylinder 5 is started to use the hydraulic rod 6 to control the upper mold base 7 to be lowered to die-cast the raw material, the upper mold base 7 and the inner walls of the lower mold base 2 can be detachably connected to a mold body 8, the upper mold base 7 is lowered so that the upper and lower groups of mold bodies 8 cooperate with each other to die-cast the raw material, the inner wall of the mold body 8 is rotatably connected to a threaded rod 9, the end of the threaded rod 9 is fixedly connected to a knob 13, and the knob is turned 13 makes the threaded rod 9 rotate, and the outer wall of the threaded rod 9 is threadedly connected with a transmission component, and the transmission component includes two groups of threaded sleeves 10, and the inner walls of the two groups of threaded sleeves 10 are set to reverse threads. As the threaded rod 9 rotates, they move closer to or separate from each other, and the inner walls of the two groups of threaded sleeves 10 are threadedly connected to the outer wall of the threaded rod 9. The outer wall of the threaded sleeve 10 is hinged with a bracket 11. The position change of the threaded sleeve 10 drives the angle deviation of the bracket 11. The end of the bracket 11 is hinged with a clamping block 12. The angle deviation of the bracket 11 pulls the two groups of clamping blocks 12 to be retracted or unfolded. The end of the transmission component is hinged with a clamping block 12, and the outer wall of the clamping block 12 is slidably connected to the inner wall of the mold body 8. The inner walls of the upper mold seat 7 and the lower mold seat 2 are both provided with a clamping groove 14, and the outer wall of the clamping block 12 is clamped with the inner wall of the clamping groove 14. The clamping block 12 is clamped into the clamping groove 14 to fix the mold body 8 on the upper and lower groups of mold seats.

[0032] Reference Figure 1 and Figure 4 The inner wall of the lower mold base 2 is slidably connected with two groups of extrusion plates 15, and a handle 19 is fixedly connected between the two groups of extrusion plates 15. The handle 19 is pressed inward to move the two groups of extrusion plates 15 to the inner side of the lower mold base 2. The lower mold base 2 is elastically connected with a trapezoidal block 17 through a return spring 16. The extrusion plates 15 move inward, thereby squeezing the inclined surface of the trapezoidal block 17 to move it upward. One end of the return spring 16 is fixedly connected to the inner wall of the lower mold base 2, and the other end of the return spring 16 is fixedly connected to the top of the trapezoidal block 17. The bottom of the trapezoidal block 17 is snap-connected with the inner wall of the notch of the extrusion plate 15. The trapezoidal block 17 squeezes the reset spring 16 to move upward. At the same time, the elastic force generated by the deformation of the reset spring 16 gives the trapezoidal block 17 a downward thrust to reset it. The top of the trapezoidal block 17 is fixedly connected with an ejector pin 18. The outer wall of the ejector pin 18 is slidably connected to the inner wall of the lower mold base 2. The outer wall of the ejector pin 18 is slidably connected to the inner wall of the mold body 8. The upward movement of the trapezoidal block 17 will drive the ejector pin 18 to lift and demould the cooled oil distribution plate.

[0033] Working principle: inject molten iron into the cavity of the mold body 8, start the hydraulic cylinder 5 to control the hydraulic rod 6 to drive the upper mold seat 7 and the upper mold body 8 to lower the raw material for die-casting, and after it cools down, push the handle 19 to drive the extrusion plate 15 to slide inward, and extrude the trapezoidal block 17 from its notch, and the extrusion return spring 16 drives the ejector pin 18 to rise and eject the cooled oil distribution plate from the cavity of the mold body 8 to achieve rapid demoulding. After demoulding, pull the handle 19 outward to move the extrusion plate 15 outward until the notch is aligned with the trapezoidal block 17, and the return spring 16 pushes the trapezoidal block 17 into the notch to lower the ejector pin 18 again. When replacing the corresponding mold body 8 according to the different specifications of the production oil distribution plate, turn the knob 13 to rotate the threaded rod 9, thereby driving the two sets of threaded sleeves 10 to separate from each other, driving the bracket 11 to deflect at an angle and drive the card block 12 to be pulled out of the card slot 14. At this time, the mold body 8 can be removed for replacement, and the replacement method is simple without the help of additional auxiliary tools.
