Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a casting mold for the upper pulley of a hydraulic press. Background Art

[0002] A casting mold is a mold used for manufacturing plastic products. It compresses thermoplastic or thermosetting plastics at high temperatures to form. Such a mold usually consists of an upper mold and a lower mold, and a closed space is formed between them, called a cavity.

[0003] During the compression processing, the material needs to be completely condensed and solidified before the mold can be formed. However, relying solely on natural placement for cooling, the rate is slow, which will lead to a decrease in processing efficiency. And during the processing, the temperature on the surface of the mold may be affected by the temperature difference, resulting in uneven surface temperature. If directly formed, it will lead to unstable dimensions of the formed parts and internal stress problems. Content of the Utility Model

[0005] The utility model is realized by the following technical solutions: A casting mold for the upper pulley of a hydraulic press includes an operation box. The inner walls on both sides of the operation box are provided with first chutes. A movable template is slidably connected to the inside of the first chutes through first sliders. A blowing component is arranged at the rear end of the operation box.

[0006] The blowing component includes an assembly plate. One side of the assembly plate is fixedly connected to the rear end of the operation box. Grooves are provided on the surface of the assembly plate. Frames are fixedly installed on both sides of the inner wall of the grooves through bolts. A blowing fan body is arranged inside the frames.

[0007] Through the above technical solutions, the frames are fixedly installed in the grooves on the surface of the assembly plate through bolts around, which is convenient for personnel to disassemble the frames and the blowing fan body later and clean and maintain the blowing fan body. When the blowing fan body works, it can accelerate the air flow rate around, help the mold cool quickly, thereby accelerating the cooling speed of the mold, improving production efficiency, avoiding the problem that the mold takes a long time to form and solidify through natural cooling, and through the blowing of the blowing fan body, the surface temperature of the formed mold can be made more uniform, which helps to reduce the problems of unstable dimensions of the formed parts and internal stress caused by local temperature differences.

[0008] As a further improvement of the above solution, the upper surface of the first slider is fixedly connected with an electric push rod, and the other end of the electric push rod is arranged on the inner wall of the first chute.

[0009] Through the above technical solution, after the electric push rod is started, it can drive the moving template to lift along the first chute through the first sliders on both sides, so as to inject the material and achieve the effect of mold forming.

[0010] As a further improvement of the above solution, a pouring block is fixedly installed on the lower surface of the moving template through a bolt group.

[0011] Through the above technical solution, since the pouring block is installed through a bolt group, it is convenient for personnel to disassemble and replace the pouring block according to the sizes of different components, improving the functionality of the device.

[0012] As a further improvement of the above solution, second chutes are opened on both sides of the front end of the operation box, and second sliders are slidably connected inside the second chutes.

[0013] Through the above technical solution, the second sliders slide inside the second chutes, which can limit and protect the fixed mold base. At the same time, the sliding connection facilitates personnel to quickly disassemble the fixed mold base and take out the internal forming mold.

[0014] As a further improvement of the above solution, a fixed mold base is fixedly connected to the surface of the second slider, and a cavity is opened on the surface of the fixed mold base.

[0015] Through the above technical solution, personnel put the heated material into the cavity, and then drive the moving template and the pouring block to descend through the electric push rod to inject the material, thus completing the mold processing.

[0016] As a further improvement of the above solution, the cavity is adapted to the pouring block.

[0017] Through the above technical solution, the pouring block descends into the cavity to process and inject the material inside the cavity.

[0018] As a further improvement of the above solution, a handle is fixedly connected to the front end of the fixed mold base, and the number of the handles is two, which are respectively fixedly connected to both sides of the front end of the fixed mold base.

[0019] Through the above technical solution, personnel can quickly pull out the fixed mold base through the handle, and then personnel can quickly take out the internal forming mold of the fixed mold base, improving the overall efficiency.

[0031] The blowing component 5 includes an assembly plate 501. One side of the assembly plate 501 is fixedly connected to the rear end of the operation box 1. Grooves 502 are formed on the surface of the assembly plate 501. On both sides of the inner wall of the groove 502, frames 503 are fixedly installed by bolts. A blowing fan body 504 is arranged inside the frame 503. The frame 503 is fixedly installed in the groove 502 on the surface of the assembly plate 501 through bolts around it, which facilitates subsequent disassembly of the frame 503 and the blowing fan body 504 by personnel and cleaning and maintenance of the blowing fan body 504. When the blowing fan body 504 works, it can accelerate the air flow rate around, help the mold cool quickly, thus accelerating the cooling speed of the mold, improving production efficiency, avoiding the problem of slow mold forming and curing through natural cooling, and through the blowing of the blowing fan body 504, the surface temperature of the formed mold can be made more uniform, which helps to reduce the problems of unstable size and internal stress of the formed parts caused by local temperature difference.

[0032] The upper surface of the first slider 3 is fixedly connected with an electric push rod 6. The other end of the electric push rod 6 is arranged on the inner wall of the first chute 2. After the electric push rod 6 is started, it can drive the moving template 4 to move up and down along the first chute 2 through the first sliders 3 on both sides, so as to carry out pressure casting on the material to achieve the effect of mold forming.

[0033] The lower surface of the moving template 4 is fixedly installed with a pressure casting block 7 through a bolt group. Since the pressure casting block 7 is installed through a bolt group, it is convenient for personnel to disassemble and replace the pressure casting block 7 according to the size of different parts, improving the functionality of the device.

[0034] Second chutes 8 are formed on both sides of the front end of the operation box 1. Second sliders 9 are slidably connected inside the second chutes 8. The second sliders 9 sliding inside the second chutes 8 can limit and protect the fixed mold base 10, and at the same time, the sliding connection facilitates personnel to promptly disassemble the fixed mold base 10 and take out the formed mold inside.

[0035] The surface of the second slider 9 is fixedly connected with a fixed mold base 10. A cavity 11 is formed on the surface of the fixed mold base 10. Personnel put the heated material into the cavity 11, and then drive the moving template 4 and the pressure casting block 7 to descend through the electric push rod 6 to carry out pressure casting on the material, thus completing the mold processing.

[0036] The cavity 11 is adapted to the pressure casting block 7. The pressure casting block 7 descends into the cavity 11 to process and pressure cast the material inside the cavity 11.

After the electric push rod 6 is started, it can drive the moving template 4 to move up and down along the first sliding groove 2 through the first sliders 3 on both sides. The moving template 4 descends, thereby driving the injection block 7 to descend, and injecting the material inside the cavity 11 to achieve the effect of mold forming. Since the injection block 7 is installed through a bolt group, it is convenient for the operator to disassemble and replace the injection block 7 according to the size of different parts, improving the functionality of the device. The frame 503 is fixedly installed in the groove 502 on the surface of the assembly plate 501 through bolts around it, which is convenient for the operator to disassemble the frame 503 and the blowing fan body 504 later and clean and maintain the blowing fan body 504. When the blowing fan body 504 is working, it can accelerate the air flow rate around it, help the mold cool quickly, thereby accelerating the cooling speed of the mold, improving production efficiency, and avoiding the problem of slow solidification of the mold formed by natural cooling. Moreover, through the blowing of the blowing fan body 504, the surface temperature of the formed mold can be made more uniform, which helps to reduce the problems of unstable dimensions and internal stress of the formed parts caused by local temperature difference. When the processing is completed, the operator can timely pull out the fixed mold base 10 through the handle 12, and then the operator can quickly take out the formed mold inside the fixed mold base 10, improving the overall efficiency.
