[0001] This utility model application relates to the field of hexagonal bolt technology, specifically a hexagonal bolt metal casting sealing mold. Background Technology

[0002] A hex bolt is a fastener consisting of a head and a threaded cylinder. It is used with a nut to fasten two parts with through holes. Hex bolts can be classified by material as iron bolts and stainless steel bolts, by force application as plain bolts and reamed bolts, and by head shape as hexagonal head, round head, square head, countersunk head, etc. Hexagonal head is the most common. Hex bolts are widely used in structures such as buildings, bridges, vehicles, and ships, and are characterized by high strength and durability.

[0003] Traditional hexagonal bolt production molds suffer from problems such as inaccurate mold closing, low production efficiency, and unstable product quality, which affect the production efficiency and quality of hexagonal bolts. Therefore, it is particularly important to develop a mold with a reasonable structure, simple operation, and the ability to effectively improve the production efficiency and quality of hexagonal bolts. Summary of the Invention

[0004] To address the problems of inaccurate mold closing, low production efficiency, and unstable product quality in traditional hexagonal bolt production molds, which affect the production efficiency and quality of hexagonal bolts, this utility model provides a metal casting sealing mold for hexagonal bolts to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hexagonal bolt metal casting sealing mold includes a casting machine body. One end of the casting machine body has a casting pipe. The end of the casting pipe away from the casting machine body is connected to a first casting mold. The first casting mold has casting grooves inside that correspond to the number and position of the casting pipes. The casting pipes extend into the casting grooves. A second casting mold is located at the end of the first casting mold away from the casting machine body. The second casting mold has another casting groove with the same shape as the casting groove inside the first casting mold. A limit rod is fixed to the end of the first casting mold near the second casting mold. A limit groove, matching the shape of the limit rod, is opened at the end of the second casting mold near the first casting mold. Fixing plates are symmetrically arranged on both sides of the casting machine body. The fixing plates are fixedly connected to the sides of the casting machine body and the first casting mold. A hydraulic cylinder is fixed to the top surface of each fixing plate. Fixing blocks are fixed to both sides of the second casting mold. The output end of the hydraulic cylinder is fixedly connected to the fixing blocks.

[0007] Furthermore, a sealing disc is slidably connected inside each of the casting tanks, a connecting rod is fixed to the bottom of the sealing disc, a connecting plate is fixed to the bottom of the connecting rod, and cylinders are fixed to both sides of the first casting mold, with the output ends of the two cylinders respectively fixedly connected to both ends of the connecting plate.

[0008] Furthermore, the second casting mold has an exhaust hole at the end away from the first casting mold, and the exhaust hole is connected to the inside of the limiting groove of the second casting mold.

[0009] Furthermore, a guide plate is fixed to the bottom end of the first casting mold, and the bottom surface of the second casting mold is in contact with the top surface of the guide plate.

[0010] Furthermore, the guide plate is located on the side of the connecting plate near the second casting mold, and the bottom end of the guide plate has an opening that mates with the connecting rod.

[0011] Furthermore, a vent hole is provided at the bottom of the casting tank, and the radius of the vent hole at the bottom of the casting tank is larger than the radius of the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the main body of the casting machine is connected to the casting tank inside the first casting mold through the casting pipe, and then the second casting mold is driven to close with the first casting mold through the hydraulic cylinder. At the same time, the first casting mold and the second casting mold are accurately closed by the limiting rod and the guide plate. This solves the problems of inaccurate mold closing, low production efficiency and unstable product quality in traditional hexagonal bolt production molds, which affect the production efficiency and quality of hexagonal bolts.

[0014] 2. In this utility model, a sealing disc is slidably installed inside the casting tank, and a connecting rod is fixed at the bottom of the sealing disc. At the same time, the connecting plate is moved by the cylinder, which in turn moves the connecting rod. As a result, when the first and second casting molds are closed and the main body of the casting machine injects the molten metal into the casting tank, the air inside the casting tank cannot be completely discharged. This makes it easy for air bubbles to get trapped inside the hexagonal bolts during the casting process, thus affecting the quality of the hexagonal bolts. Attached Figure Description

Detailed Implementation

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A hexagonal bolt metal casting sealing mold includes a casting machine body 1. A casting pipe 2 is provided at one end of the casting machine body 1. The end of the casting pipe 2 away from the casting machine body 1 is connected to a first casting mold 3. The first casting mold 3 has casting grooves 5 inside, corresponding in number and position to the casting pipe 2. The casting pipe 2 extends into the casting grooves 5. A second casting mold 4 is provided at the end of the first casting mold 3 away from the casting machine body 1. The second casting mold 4 has another casting groove 5 inside, identical in shape to the casting grooves 5 inside the first casting mold 3. The first casting mold 3 is close to the second casting mold 4. One end of the casting mold 4 is fixed with a limiting rod 9. The end of the second casting mold 4 near the first casting mold 3 is provided with a limiting groove that matches the shape of the limiting rod 9. Fixing plates 7 are symmetrically arranged on both sides of the casting machine body 1. The fixing plates 7 are fixedly connected to the sides of the casting machine body 1 and the first casting mold 3. A hydraulic cylinder 8 is fixed on the top surface of each fixing plate 7. Fixing blocks 6 are fixed on both sides of the second casting mold 4. The output end of the hydraulic cylinder 8 is fixedly connected to the fixing block 6. The hydraulic cylinder 8 drives the second casting mold 4 to move and the limiting rod 9 to make the mold closing of the first casting mold 3 and the second casting mold 4 more accurate.

[0023] Specifically, the second casting mold 4 has an exhaust hole 10 at the end away from the first casting mold 3. The exhaust hole 10 is connected to the limiting groove of the second casting mold 4. The bottom end of the first casting mold 3 is fixed with a guide plate 15. The bottom surface of the second casting mold 4 is in contact with the top surface of the guide plate 15, so that the guide plate 15 makes the mold closing of the first casting mold 3 and the second casting mold 4 more accurate.

[0024] As an optimization solution, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a sealing disc 11 is slidably connected inside each casting tank 5. A connecting rod 12 is fixed to the bottom of the sealing disc 11, and a connecting plate 13 is fixed to the bottom of the connecting rod 12. Cylinders 14 are fixed on both sides of the first casting mold 3. The output ends of the two cylinders 14 are fixedly connected to the two ends of the connecting plate 13 respectively, so that the sealing disc 11 exhausts air into the casting tank 5 while controlling the length of the hexagonal bolt.

[0025] Specifically, a vent hole is provided at the bottom of the casting tank 5. The radius of the vent hole at the bottom of the casting tank 5 is larger than the radius of the connecting rod 12. The guide plate 15 is located on the side of the connecting plate 13 close to the second casting mold 4. The bottom of the guide plate 15 is provided with an opening that cooperates with the connecting rod 12, so that the guide plate 15 avoids falling on the top surface of the connecting plate 13 when the hexagonal bolt is demolded.

[0026] Working principle: By activating the hydraulic cylinder 8, the fixed block 6 is moved, which in turn moves the second casting mold 4 toward the first casting mold 3. Simultaneously, the limiting rod 9 is aligned with the limiting hole on the second casting mold 4 and inserted into the limiting hole, thus ensuring accurate mold closing between the first casting mold 3 and the second casting mold 4. At this time, the casting machine body 1 is activated, which inputs molten metal into the casting tank 5 through the casting pipe 2, thus filling the casting tank 5. At the same time, the cylinder 14 is activated, which moves the connecting plate 13. The connecting plate 13 moves the sealing plate 11 downward, allowing the sealing plate 11 to expel air from the casting tank 5 and control the length of the casting tank 5. After casting and molding, the hydraulic cylinder 8 is activated, which moves the second casting mold 4 away from the first casting mold 3, causing the first casting mold 3 and the second casting mold 4 to separate, thus demolding the hexagonal bolts inside the casting tank 5.
