Technical Field

[0001] The utility model relates to the technical field of casting molds, in particular to a V-method casting mold. Background Art

[0002] In V-method casting, due to the special nature of the mold itself, the selection and design of the mold is a very important content. Generally speaking, in V-method casting, after the EVA film is baked, the film should be covered on the mold by machine or hand. Under the action of vacuum, the EVA film is covered on the mold, and then the sand box is placed. After the sand box is placed, the sand adding and compaction process will continue;

When two similar products are currently commonly used and produced by V-method casting, two sets of completely independent molds are required to complete the production of the products. As a result, when producing new products, new molds still need to be developed. In addition, the molds commonly used at present have high production costs and long cycles due to their complex shapes. Therefore, the utility model proposes a V-method casting mold to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a V-method casting mold, including a base plate 1, a mold 2 and a sandbox 3. The top of the base plate 1 is provided with the mold 2, the top of the mold 2 is provided with the sandbox 3, the top of the sandbox 3 is provided with a top plate 5, one side of the base plate 1 is provided with an assembly mechanism matching the mold 2, the top of the sandbox 3 is also provided with a covering plate 16, the top of the covering plate 16 is connected with an injection hole 17, the mold 2 is fixed to the top of the base plate 1 through the assembly mechanism, and then the top of the mold 2 is coated, and then the sandbox 3 is placed on the top of the mold 2, sand is spread on the inside of the mold 2, and then the top of the sand is coated.

[0020] The material of the sand box 3 is set to cast iron, and the interior of the sand box 3 is connected with a threaded connection valve. The length and width of the sand box 3 are smaller than the length and width of the mold 2. Then the top plate 5 is installed on the top of the sand box 3, and then the sand box 3 is evacuated to tighten the sand inside the sand box 3 through atmospheric pressure. Then, the mold is reversed so that the bottom plate 1 is facing upward, and then the bottom plate 1 and the mold 2 are removed and the covering plate 16 is installed. The casting liquid is poured into the sand cavity through the injection hole 17. After the casting is cooled and formed, the negative pressure state inside the sand box 3 is released, and the sand inside the sand box 3 collapses by itself. After the covering plate 16 is removed, it is convenient to take the casting out of the sand box 3.

[0021] The assembly mechanism includes an articulated seat 8, a fixing rod 9 and a clamping block 10. One side of the base plate 1 is hinged with a fixing rod 9 through the articulated seat 8, and the other side of the base plate 1 is connected with a clamping block 10. A clamping block 11 is provided inside the clamping block 10, and one end of the clamping block 11 is connected to a sliding rod 12, and one end of the sliding rod 12 is engaged with the inside of the fixing rod 9. The two sides of the mold 2 are symmetrically connected with plug plates 6. A limit frame 7 is provided on one side of the base plate 1. The outer wall of the plug plate 6 is engaged with the inner wall of the limit frame 7, and the bottom of the fixing rod 9 is connected with the top of the other plug plate 6. Before using the assembly structure, when the mold 2 is installed, the plug plate 6 at one end of the mold 2 is first engaged into the inside of the limit frame 7, and then the fixing rod 9 is rotated toward the limit frame 7 on the other side of the mold 2 until the bottom of the fixing rod 9 is engaged with the top of the plug plate 6 on the other side. At this time, one end of the plug plate 6 is engaged into the inside of the clamping block 10.

[0022] One end of the block 11 is hinged with a knob 15 through a pin 14, and the shape of the knob 15 is set to an "L" shaped structure. A spring 13 is provided on the outside of the block 11. Since the knob 15 is hinged with the block 11 through the pin 14, and one end of the block 11 is connected to the sliding rod 12, rotating the knob 15 outward can drive the sliding rod 12 to move toward the inside of the clamping block 10, and the spring 13 is in a compressed state. When the fixing rod 9 completely enters the interior of the clamping block 10, the internal circular hole of the fixing rod 9 and the position of the sliding rod 12 are parallel to each other. Then, the elastic force generated by the spring 13 is released to drive the sliding rod 12 into the circular hole, and one end of the fixing rod 9 is clamped together with the clamping block 10 to fix the mold 2 on the top of the base plate 1. When the mold 2 needs to be disassembled, the knob 15 is rotated outward again to pull the sliding rod 12 out of the circular hole through the block 11, and then the fixing rod 9 is pushed to rotate upward to pull the mold 2 out of the top of the base plate 1.

[0023] A group of grooves 20 are symmetrically provided on both sides of the bottom plate 1, the top plate 5 and the cover plate 16, and a connecting mechanism is provided between the top plate 5 and the bottom plate 1 and the cover plate 16, and the connecting mechanism includes a connecting rod 18 and a threaded rod 19. A connecting rod 18 is provided inside the groove 20, and the top and bottom ends of the connecting rod 18 are symmetrically connected with the threaded rod 19, and the outer side of the threaded rod 19 is threadedly connected with a nut. The grooves 20 provided in the top plate 5 and the bottom plate 1 and the cover plate 16 are parallel to each other up and down. The connecting rod 18 is inserted into the inside of the groove 20, and then the upper nuts are tightened at both ends of the connecting rod 18. The nuts are used to clamp the top plate 5 and the bottom plate 1 or the cover plate 16 to connect the top plate 5 and the bottom plate 1 or the cover plate 16 together. When disassembly is required, the nuts at the top and bottom ends of the connecting rod 18 only need to be unscrewed.

[0024] The V-method casting mold first has the plug plate 6 at one end thereof engaged into the interior of the limit frame 7, and then the fixing rod 9 is rotated in the direction of the limit frame 7 on the other side of the mold 2 until the bottom of the fixing rod 9 is in contact with the top of the plug plate 6 on the other side. At this time, one end of the fixing rod 9 is engaged into the interior of the clamping block 10, and the knob 15 is rotated outward to drive the sliding rod 12 to move toward the inner side of the clamping block 10, and the spring 13 is in a compressed state. When the fixing rod 9 completely enters the interior of the clamping block 10, the internal circular hole of the fixing rod 9 and the position of the sliding rod 12 are parallel to each other. Then, the elastic force generated by the spring 13 is released to drive the sliding rod 12 into the circular hole, and one end of the fixing rod 9 is engaged with the clamping block 10 to fix the mold 2 on the top of the bottom plate 1. When the mold 2 needs to be disassembled, the knob 15 is rotated outward again to pull the sliding rod 12 out of the circular hole through the clamping block 11, and then the fixing rod 9 is pushed to rotate upward, and the mold 2 can be pulled out from the top of the bottom plate 1, so that the mold 2 can be replaced conveniently.
