[0027] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0028] An embodiment of the present utility model discloses a PIR material casting mold with strong weather resistance.

[0029] Embodiment 1

[0030] Refer to Figures 1-4 , a PIR material casting mold with strong weather resistance, including a base 1. The upper surface of the base 1 is fixedly connected with a lower mold 2. Above the lower mold 2, there are two upper molds 3. A casting cavity is jointly arranged inside the two upper molds 3 and the lower mold 2. The upper surface of the base 1 is fixedly connected with a U-shaped plate 4. Adjusting mechanisms are arranged between the U-shaped plate 4 and the two upper molds 3. The two upper molds 3 are both moved through the adjusting mechanisms. The adjusting mechanism includes two cylinders 8. At both ends above the U-shaped plate 4, there are first inclined surfaces. The two cylinders 8 are respectively fixedly connected to the corresponding first inclined surfaces. On one side above the two upper molds 3, there is a second inclined surface. The output ends of the two cylinders 8 are respectively fixedly connected to the corresponding second inclined surfaces.

[0031] Both the lower mold 2 and the two upper molds 3 are made of metal with strong weather resistance, thereby improving the service life of the device. Starting the two cylinders 8 can move the two upper molds 3, thus facilitating the removal of the workpiece inside the casting cavity.

[0032] Refer to Figures 1-3 , installation grooves are opened on both sides of the U-shaped plate 4. Inside the two installation grooves, air chambers 5 are fixedly connected. Inside the two air chambers 5, pistons 6 are slidably arranged. One end of each of the two pistons 6 is fixedly connected with a connecting rod 7. One end of each of the two connecting rods 7 penetrates through one side of the air chamber 5. A cavity is opened inside the lower mold 2. Multiple air outlet holes are opened between the cavity and the casting cavity. Air delivery mechanisms are arranged between the cavity and the two air chambers 5. The air delivery mechanism includes a first connecting pipe 9, two second connecting pipes 10, and a three-way joint 11. Multiple first installation holes are opened on the lower surface of the cavity. The first connecting pipe 9 is fixedly connected inside the first installation hole. On the lower surface of one end of each of the two air chambers 5, a second installation hole is opened. The two second connecting pipes 10 are respectively fixedly connected inside the corresponding second installation hole. The lower end of the first connecting pipe 9 penetrates through the upper surface of the base 1 and is fixedly connected with one end of the three-way joint 11. One end of each of the two second connecting pipes 10 is fixedly connected with the other two ends of the three-way joint 11.

[0033] Moving the two connecting rods 7, then the two pistons 6 can be moved. Next, the two pistons 6 can squeeze the air inside the corresponding air chambers 5 into the cavity through the first connecting pipe 9 and the two second connecting pipes 10. Subsequently, the air can be discharged through each air outlet hole, and the workpiece can be blown out, thereby preventing the workpiece from adhering to the inner wall of the lower mold 2 to facilitate the staff to take out the workpiece.

[0034] Embodiment 2

[0035] On the basis of Embodiment 1, refer to Figures 1-2, on one side of each of the two upper molds 3, an L-shaped extrusion plate 12 is fixedly connected, and the two L-shaped extrusion plates 12 respectively match the corresponding connecting rods 7.

[0036] When the two upper molds 3 move, the two L-shaped extrusion plates 12 respectively follow the corresponding upper molds 3 to move and extrude the corresponding connecting rods 7, so that the two connecting rods 7 can move.

[0037] Embodiment Three

[0038] On the basis of Embodiment Four, referring to Figures 1-2 , one end of each of the two connecting rods 7 is hemispherical, and one end of each of the two connecting rods 7 is in contact with one side of the corresponding L-shaped extrusion plate 12.

[0039] Because one end of each of the two connecting rods 7 is hemispherical, the friction between it and the corresponding L-shaped extrusion plate 12 can be reduced.

[0040] Embodiment Four

[0041] On the basis of Embodiment One, referring to Figure 2 , a plurality of return springs 13 are fixedly connected between the inner walls of the two pistons 6 and the corresponding air chambers 5.

[0042] The elastic force of each return spring 13 can be used to push the piston 6 to reset when the two upper molds 3 are combined with the lower mold 2, so that the connecting rod 7 can be reset.

[0043] Embodiment Five

[0044] On the basis of Embodiment One, referring to Figures 2-3 , a first one-way valve 14 is fixedly connected inside each air outlet hole.

[0045] Each first one-way valve 14 can be used to prevent the casting liquid from entering the interior of the cavity.

[0046] Embodiment Six

[0047] On the basis of Embodiment One, referring to Figure 2 , air inlet holes are provided on one side of each of the two air chambers 5, and second one-way valves 15 are fixedly connected inside the two air inlet holes.

[0048] The two second one-way valves 15 enable air to enter the interior of the air chamber 5 when the piston 6 resets, and at the same time prevent the air from being discharged from the air inlet when the piston 6 squeezes the air.

[0049] Embodiment Seven

[0050] On the basis of Embodiment One, referring to Figures 1-2 , a material feeding hole 16 is provided on the upper surface of the casting cavity.

[0051] The casting liquid can be conveniently added into the interior of the casting cavity by using the material feeding hole 16.

[0052] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
