Description

Technical Field

[0001] This utility model relates to the field of wax injection machine technology, specifically a wax injection machine with a liquid spraying component. Background Technology

[0002] Wax injection machines are core equipment in the precision casting field. They inject molten wax into a mold cavity, which cools to form a wax pattern, providing a basic blank for subsequent shell making, casting, and other processes. During the wax injection molding process, the wax pattern and the mold cavity wall are prone to adhesion due to factors such as molecular adsorption and temperature differences, leading to difficulties in demolding. This can not only cause deformation and damage to the wax pattern, affecting product precision, but also prolong the production cycle and reduce production efficiency.

[0003] Currently, the industry commonly uses manual spraying of release agent to solve the adhesion problem. However, this method has obvious limitations. Manual spraying makes it difficult to ensure uniform coverage of the release agent. Excessive spraying in certain areas can easily lead to defects on the surface of the wax mold, while insufficient spraying will not achieve effective demolding. Furthermore, manual operation must be carried out in the gap between mold opening and closing, which poses safety hazards and has low work efficiency, making it difficult to adapt to the high-efficiency production requirements of automated production lines. Therefore, a wax injection machine with a spraying component is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a wax injection machine with a liquid spraying component to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wax injection machine with a spraying component, comprising a main body, a base at the bottom of the main body, a first fixed seat at one end of the main body, a second fixed seat at one end of the base, a first long connecting rod rotatably mounted at one end of the second fixed seat, a second long connecting rod rotatably mounted at one end of the first fixed seat, guide posts penetrating the sides of the first and second long connecting rods, a first short connecting rod rotatably mounted at one end of the second long connecting rod, a second short connecting rod rotatably mounted at one end of the first long connecting rod, one end of the first and second short connecting rods being connected, a guide rod mounted on the side of the second short connecting rod, a connecting block mounted at one end of the guide rod, and multiple spraying pipes mounted at one end of the connecting block.

[0006] Preferably, a rotating shaft is installed at one end of both the first fixed base and the second fixed base, and one end of the first short connecting rod and the second short connecting rod are connected by the rotating shaft.

[0007] Preferably, the connecting block has multiple mounting slots, and the mounting block is installed in the mounting slots. The spray pipe is connected to the mounting block.

[0008] Preferably, the first and second fixing seats are provided with connecting columns on their sides, and the connecting columns are provided with two fixing sleeves on their sides.

[0009] Preferably, a pressure plate is installed at one end of the main body of the device, a mold adapted to the pressure plate is installed at one end of the base, and a guide pressure rod is installed on the side of the main body of the device.

[0010] Preferably, a limiting groove is formed in the guide rod, and one end of the guide post is installed in the limiting groove.

[0011] Preferably, the guide rod is slidably mounted on the side of the first long connecting rod and the second long connecting rod by means of the guide post.

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

[0013] (1) This utility model sets up a first fixed seat and a second fixed seat, and sprays release agent onto the mold through multiple spray pipes to assist in demolding after pressing. When the main body of the device is pressed down, it drives the first fixed seat and the second fixed seat to rotate. The rotation of the first short connecting rod and the second short connecting rod drives the guide rod to move. One end of the guide rod is limited by the connecting column and moves in a straight line, thereby driving the connecting block and the spray pipe to move away from the main body of the device and taking the spray pipe out of the working area. After pressing is completed, it cooperates with the demolding structure to continue spraying release agent after demolding. There is no need for manual spraying, which improves production efficiency.

[0014] (2) By setting up connecting columns and fixing sleeves, this utility model allows for the adjustment of the spraying range of the spray pipe by adjusting the positions of the first long connecting rod and the second long connecting rod on the sides of the device body and the base. By moving one end of the first long connecting rod and the second long connecting rod on the connecting column, the installation positions of the first fixing seat and the second fixing seat can be adjusted. The connection of the connecting column is fixed by two fixing sleeves to abut and fix the two sides together, thus completing the installation of the first long connecting rod and the second long connecting rod. At this time, the spray pipe can be installed or removed according to the working area. By installing one end of the mounting block in different mounting slots, the angle of the spray pipe can be adjusted, thereby improving the applicability of the device body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a wax injection machine with a spraying component, comprising a main body 1, a base 2 at the bottom of the main body 1, a first fixed seat 3 installed at one end of the main body 1, a second fixed seat 4 installed at one end of the base 2, a first long connecting rod 5 rotatably installed at one end of the second fixed seat 4, a second long connecting rod 6 rotatably installed at one end of the first fixed seat 3, guide posts 7 penetrating the sides of the first long connecting rod 5 and the second long connecting rod 6, a first short connecting rod 8 rotatably installed at one end of the second long connecting rod 6, and a second short connecting rod 9 rotatably installed at one end of the first long connecting rod 5. One end of the first short connecting rod 9 is connected to the second short connecting rod 9. A guide rod 10 is installed on the side of the second short connecting rod 9. A connecting block 11 is installed on one end of the guide rod 10. Multiple spray pipes 12 are installed on one end of the connecting block 11. A rotating shaft 13 is installed on one end of the first fixed seat 3 and the second fixed seat 4. One end of the first short connecting rod 8 and the second short connecting rod 9 is connected through the rotating shaft 13. A mold 19 that matches the pressure plate 18 is installed on one end of the base 2. A guide pressure rod 20 is installed on the side of the main body 1 of the device. A limit groove 21 is opened in the guide rod 10. One end of the guide column 7 is installed in the limit groove 21. The guide rod 10 slides through the limit of the guide column 7. Installed on the sides of the first long connecting rod 5 and the second long connecting rod 6, when molding is required, release agent is sprayed onto the mold 19 through the ends of multiple spray pipes 12 to help the main body 1 of the device quickly demold. Multiple limiting grooves 21 provide limiting. As the main body 1 presses down, it drives the first fixed seat 3 to move towards the second fixed seat 4, thereby causing the first long connecting rod 5 and the second long connecting rod 6 to rotate. The rotating shaft 13 at the end connects to the first short connecting rod 8 and the second short connecting rod 9, simultaneously adjusting the included angle between the first short connecting rod 8 and the second short connecting rod 9 to decrease. This is achieved through one end of the first short connecting rod 8 and the second short connecting rod 9... The rotating shaft 13 is connected to one end of the guide rod 10, which drives the guide rod 10 to move. This causes the guide column 7 to slide within the limiting groove 21. The limiting groove 21 then drives the guide rod 10 to move linearly, which in turn drives the spray pipe 12 to move away from the main body 1 of the device. After moving out of the working area, the molding operation is performed. When the main body 1 of the device returns to its original position, the first long connecting rod 5 and the second long connecting rod 6 drive the first short connecting rod 8 and the second short connecting rod 9 to return to their original positions. The guide rod 10 then drives the spray pipe 12 to return to its original position and re-spray the release agent, completing one operation. This eliminates the need for manual spraying of the release agent by the staff, thus improving production efficiency.

[0022] Example 2: Figure 3 and 4As shown, the connecting block 11 has multiple mounting slots 14, and mounting blocks 15 are installed in the mounting slots 14. The spray pipe 12 is connected to the mounting block 15. Connecting columns 16 are installed on the sides of the first fixed seat 3 and the second fixed seat 4. Two fixing sleeves 17 are installed on the sides of the connecting columns 16. A pressure plate 18 is installed at one end of the device body 1. When it is necessary to adjust the spraying position of the spray pipe 12, the positions of the first long connecting rod 5 and the second long connecting rod 6 on the sides of the device body 1 and the base 2 can be adjusted. The position of the first fixed seat 3 and the second fixed seat 4 can be adjusted by moving the connecting column 16. The connection between the connecting column 16 and the first fixed seat 3 and the second fixed seat 4 is fixed by two fixing sleeves 17 to abut and fix the two sides together, thus completing the installation of the first long connecting rod 5 and the second long connecting rod 6. At this time, the spray pipe 12 can be installed or removed according to the working area. The spray pipe 12 can be adjusted by installing one end of the mounting block 15 in different mounting slots 14 and adjusting the bending angle of the spray pipe 12, which improves the applicability of the device body 1. The remaining features are the same as in Embodiment 1.

[0023] The working principle is as follows: When molding is required, release agent is sprayed onto the mold 19 through the ends of multiple spray pipes 12 to help the main body 1 of the device quickly demold. The limiting groove 21 in the guide rod 10 cooperates with the guide post 7 for limiting. As the main body 1 presses down, it drives the first fixed seat 3 to move towards the second fixed seat 4, thereby driving the first long connecting rod 5 and the second long connecting rod 6 to rotate. The rotating shaft 13 at the end connects to the first short connecting rod 8 and the second short connecting rod 9, simultaneously reducing the angle between the first short connecting rod 8 and the second short connecting rod 9. The rotating shaft 13 at one end of the first short connecting rod 8 and the second short connecting rod 9 connects to one end of the guide rod 10, causing the guide rod 10 to move. This causes the guide post 7 to slide within the limiting groove 21. The limiting groove 21 causes the guide rod 10 to move linearly, thereby moving the spray pipes 12 away from the main body 1 of the device. After moving out of the working area, the molding operation is performed. When the main body 1 of the device returns to its original position, the first long connecting rod 5 and the second long connecting rod... 6 drives the first short connecting rod 8 and the second short connecting rod 9 back to their original positions, and the guide rod 10 drives the spray pipe 12 back to its original position to re-spray the release agent, completing one operation. This eliminates the need for manual spraying of the release agent by workers, improving production efficiency. When it is necessary to adjust the spraying position of the spray pipe 12, the installation positions of the first long connecting rod 5 and the second long connecting rod 6 on the connecting column 16 can be adjusted. By moving one end of the first long connecting rod 5 and the second long connecting rod 6 on the connecting column 16, the installation positions of the first fixed seat 3 and the second fixed seat 4 can be adjusted. At the connection between the connecting column 16 and the first fixed seat 3 and the second fixed seat 4, two fixing sleeves 17 are used to abut from both sides to fix the positions of the first long connecting rod 5 and the second long connecting rod 6, completing the installation of the first long connecting rod 5 and the second long connecting rod 6. At this time, the spray pipe 12 can be installed or removed according to the work area. By installing one end of the mounting block 15 in different mounting slots 14, the bending angle of the spray pipe 12 can be adjusted to adapt to different work requirements, improving the applicability of the main body 1 of the device.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
