Description

Technical Field

[0001] The utility model relates to the technical field of precision castings, in particular to a precision casting processing and forming device. Background Art

[0002] The products of precision casting are precise, complex, and close to the final shape of the parts, and can be directly used without machining or with very little machining. It is an advanced process with high-precision forming.

[0003] Temperature control has a very great influence on the forming precision of castings. If the temperature is too low, it is easy to cause defects such as pores and shrinkage porosity inside the castings. If the temperature is too high, it will cause surface cracks and oxidation problems of the castings. In the prior art, the high or low temperature of the castings mainly depends on the daily experience of on-site workers. Therefore, it is difficult to accurately control the quality of the castings. Summary of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a precision casting processing and forming device, which is used to solve the problem that it is difficult to accurately control the temperature of castings in the prior art.

[0005] To achieve the above purpose and other related purposes, the present utility model provides the following technical solutions:

[0006] A precision casting processing and forming device includes a bottom plate, a top plate, support columns arranged between the bottom plate and the top plate, a moving module arranged on one side of the top plate, and a fixed module corresponding to the moving module arranged on one side of the bottom plate; a guiding component is arranged between the moving module and the top plate, a driving device for driving the moving module to approach or move away from the fixed module is arranged on the top plate, and a positioning component is arranged between the moving module and the fixed module; a heating device is arranged on the moving module, a cooling device is arranged on the fixed module, and both the heating device and the cooling device are connected to a control system to ensure that the processing and forming temperature of the casting is within a set threshold.

[0007] Implementing the above technical solution, in the present application, the driving device is used to drive the moving module to approach or move away from the fixed module, so as to complete the mold closing or mold opening action. The guiding component and the positioning component can ensure accurate mold closing, thereby ensuring the casting precision. Temperature control during the forming process of the casting is very important. If the temperature is too low, it is easy to cause defects such as pores and shrinkage porosity inside the castings. If the temperature is too high, it will cause surface cracks and oxidation problems of the castings. Through the setting of the control system in the present application, the temperature during the forming process of the casting can be collected in real time. When the temperature is lower than the threshold, the heating device can be turned on, and when it is higher than the threshold, the cooling device can be turned on, thereby ensuring the forming temperature of the casting and guaranteeing the quality of the casting.

[0008] In an embodiment of the present utility model, the moving module includes a moving template, a moving mold base, and a core arranged in sequence from top to bottom. A sprue bushing is provided on the moving mold base, and a pouring runner communicating with the sprue bushing and penetrating through the moving template and the core is provided.

[0009] To implement the above technical solution, during the working process, the moving module and the fixed module are first closed. Molten metal liquid enters from the sprue bushing and flows through the pouring runner into the space between the core and the cavity. After pressure holding and temperature control, the casting is formed.

[0010] In an embodiment of the present utility model, the fixed module includes a fixed mold base arranged on the bottom plate and a cavity arranged on the fixed mold base.

[0011] To implement the above technical solution, after the casting is formed, the casting can be taken out of the cavity through a pushing device and a material taking device.

[0012] In an embodiment of the present utility model, the heating device includes a heating cavity and a heat preservation cavity circumferentially opened on the core. A plurality of heating tubes are evenly distributed in the heating cavity, and heat preservation materials are provided in the heat preservation cavity.

[0013] To implement the above technical solution, if the metal liquid freezes at the bottom of the pouring runner, the pouring runner will be blocked, affecting the formation of the next casting. Therefore, the setting of the heating tubes and heat preservation materials can keep the metal liquid warm and prevent freezing.

[0014] In an embodiment of the present utility model, the cooling device includes a cooling flow path arranged circumferentially around the cavity and a driving pump communicating with the cooling flow path.

[0015] To implement the above technical solution, the driving pump can evenly arrange the refrigerant along the cooling flow path circumferentially around the cavity, thereby cooling the cavity and facilitating the formation of the casting.

[0016] In an embodiment of the present utility model, the positioning component includes a positioning hole opened on the cavity and a positioning post arranged on the core and capable of being embedded in the positioning hole.

[0017] To implement the above technical solution, the setting of the positioning hole and the positioning post can ensure the alignment degree of the fixed module and the moving module and prevent the fixed module and the moving module from being misaligned.

[0018] In an embodiment of the present utility model, the guiding component includes a guide bushing arranged on the top plate and a guide post passing through the guide bushing and fixed to the upper end of the moving template.

[0019] To implement the above technical solution, by setting the guide pillars and guide sleeves, the alignment problem between the moving die module and the fixed die module can be ensured, and the influence on the molding of the casting due to inaccurate positioning can be avoided.

[0020] In an embodiment of the present utility model, the cooling channel is serpentine or annular, and the refrigerant in the cooling channel is water, oil or gas.

[0021] To implement the above technical solution, the refrigerant can be set as needed, and the travel of the refrigerant is increased through the annular or serpentine cooling channel, improving the heat dissipation and temperature reduction effect of the casting.

[0022] As described above, a precision casting processing and molding device of the present utility model has the following beneficial effects: In this application, the driving device is used to drive the moving die module to approach or move away from the fixed die module, thereby completing the mold closing or mold opening action. The guiding component and the positioning component can ensure accurate mold closing, thus guaranteeing the casting accuracy. Temperature control during the casting molding process is very important. Too low temperature is likely to cause defects such as internal pores and shrinkage porosity in the casting, and too high temperature will lead to surface cracks and oxidation problems in the casting. Through the setting of the control system in this application, the temperature during the casting molding process can be collected in real time. When the temperature is lower than the threshold value, the heating device can be turned on, and when it is higher than the threshold value, the cooling device can be turned on, thereby ensuring the molding temperature of the casting and guaranteeing the quality of the casting.

The guiding component and the positioning component can ensure accurate mold closing, thereby ensuring the accuracy of the casting. Temperature control during the forming process of the casting is very important.
