Description

Technical Field

[0001] The present invention relates to the technical field of sand casting, and more particularly to a sand casting mold. Background Art

[0002] Sand casting mold is a common casting mold used to produce metal castings of various shapes and sizes. It is made of high temperature resistant sand material, usually quartz sand or clay sand. The mold forms the cavity of the casting through the combination of the mold core and the shell, and then the molten metal is poured into the cavity. After the metal cools and solidifies, the mold is opened to obtain the casting of the desired shape. Sand casting molds are inexpensive to make and are suitable for small batches and large castings.

[0003] However, after filling the sand casting mold with clay sand, it needs to be compacted to ensure the integrity of the mold. However, the clay sand is easy to overflow during the compaction process, resulting in waste of resources and cumbersome cleaning later. At the same time, it takes a lot of time to ensure the alignment of the overlapping molds to avoid subsequent molding quality problems, affecting work efficiency.

[0004] In view of this, we propose sand casting mold. Utility Model Content

[0019] The present application is further described in detail below in conjunction with the accompanying drawings.

[0020] Reference Figure 1-Figure 3The embodiment of the present application provides a sand casting mold, including a mold plate 1, a sand frame 2 is provided above the mold plate 1, and positioning cylinders 3 are fixedly connected at the four corners of the outer periphery of the sand frame 2, a guide plate 4 is provided below the mold plate 1, and a material guide frame 5 is provided below the guide plate 4, and the material guide frame 5 is inclined, and a support rod 6 is fixedly connected to the lower end surface of the guide plate 4, and the support rod 6 passes through the material guide frame 5 and is fixedly connected to the material guide frame 5. During the compaction process of the clay sand inside the sand frame 2, the clay sand is discharged from one end of the material guide frame 5 through the guide plate 4 and the material guide frame 5, which is convenient for the staff to collect the overflowed clay sand, effectively controls the flow and collection of the clay sand, reduces the waste of clay sand and unnecessary cleaning work, and improves the material utilization rate;

[0021] An insert rod 15 is slidably connected to the lower part of the interior of the positioning cylinder 3, and an adjustment block 16 is fixedly connected to the outer wall of the insert rod 15. A rigid spring 17 is movably inserted into the interior of the insert rod 15, and one end of the rigid spring 17 is fixedly connected to the positioning cylinder 3. The insert rod 15 inside the positioning cylinder 3 can position the mold plate 1, and can also ensure the precise positioning and fixation of the mold plate 1 and the sand frame 2 by inserting the insert rod 15 of one group of sand frames 2 into the positioning cylinder 3 of another group of sand frames 2, which helps to ensure the accuracy and consistency of the material after later molding.

[0022] Reference Figure 1 and Figure 2 The lower end surface of the support rod 6 is fixedly connected with the bottom plate 7, the four corners of the upper end surface of the mold plate 1 are provided with sockets 10, the front and rear of the upper end surface of the mold plate 1 are provided with positioning strips 11, the upper end surface of the mold plate 1 is fixedly connected with a model block 12, the end surface of the guide plate 4 close to the mold plate 1 is provided with a slot 8, the end surface of the mold plate 1 close to the guide plate 4 is fixedly connected with a card plate 9, and the card plate 9 corresponds to the slot 8, the sockets 10 and the positioning strips 11 both play a good positioning role to prevent the mold plate 1 from being misaligned with the sand frame 2.

[0023] Reference Figure 3 A slide groove 13 is provided on the outer wall of the positioning cylinder 3, and limiting grooves 14 are provided at both ends of the slide groove 13. The adjustment block 16 extends out of the slide groove 13, and the adjustment block 16 can slide in the slide groove 13 and the limiting groove 14. The limiting groove 14 serves to limit the adjustment block 16 to prevent the insertion rod 15 from shaking and affecting the positioning effect during use.

[0024] Working principle: the staff first inserts the card plate 9 under the mold plate 1 into the card slot 8 on the guide plate 4. After the mold plate 1 is placed, the insertion rod 15 inside the positioning tube 3 at the four corners of the sand frame 2 is inserted into the insertion hole 10 on the mold plate 1. The positioning strip 11 on the mold plate 1 clamps the sand frame 2. After the sand frame 2 is placed, the staff pours the clay sand into the sand frame 2. Then the staff places the bottom plate 7 under the tamping machine. The tamping machine tamps the clay sand inside the sand frame 2. During the tamping process, clay sand will leak out. The falling clay sand will fall into the guide frame 5 through the inclined surface on the guide plate 4. Since the guide frame 5 is in an inclined state, the clay sand will be discharged from one end of the guide frame 5, which is convenient for the staff to collect. After the tamping is completed, the mold plate 1 and the sand frame 2 are first removed from the guide plate 4, and then another set of mold plates 1 and sand frames 2 are tamped.

[0025] Select a group of sand frames 2, push the adjusting block 16 inside the positioning cylinder 3 in turn, the adjusting block 16 slides out from the limiting groove 14 and enters the sliding groove 13, the adjusting block 16 moves in the sliding groove 13, the adjusting block 16 moves to drive the insertion rod 15, the insertion rod 15 enters the interior of the positioning cylinder 3, and the rigid spring 17 is tightened until the adjusting block 16 moves to the other end of the sliding groove 13, and then the adjusting block 16 slides into the limiting groove 14 at the other end, so as to fix the insertion rod 15 in the positioning cylinder 3, and then remove the mold plate 1 from the sand frame 2, fit the mold surfaces of the two sand frames 2 together, and at the same time, the insertion rod 15 on one group of sand frames 2 will be inserted into the positioning cylinder 3 on the other group of sand frames 2, so as to quickly and accurately fit the two sand frames 2 together, and after stacking is completed, press the two sand frames 2, and finally pour the inside of the sand frame 2.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
