[0047] The number of the upper cavities is two, and the number of the lower cavities is two.

[0048] The working principle of the present invention is:

[0049] Mold installation and preparation stage

[0050] First, install the mold on the corresponding device, and accurately adjust the mold position through the bottom plate air floating structure to ensure the accuracy of subsequent operations.

[0051] The mold is connected to cooling water with a temperature controlled at 30℃-40℃ to keep the mold temperature within an appropriate range and reduce the fluctuation of the wax mold size.

[0052] Moulding process

[0053] The hydraulic system starts to drive the upper mold base and the lower mold base to close the mold, ensuring that the upper mold base and the lower mold base are tightly closed to form a complete cavity.

[0054] In this process, the oblique guide assembly plays a role. The upper guide seat and the lower guide seat are respectively in contact with the upper mold base and the lower mold base, and the oblique guide column in the lower guide seat cooperates with the oblique slide block sleeved on it in the upper guide seat to ensure the precise movement of each component during mold closing.

[0055] The leaf crown slider assembly is also involved. The upper inclined guide column drives the leaf crown slider to move through the second inclined slider connected to the outside, so that the leaf crown slider is in the correct position when the mold is closed, preparing for the wax mold molding.

[0056] Wax injection process

[0057] After the mold is closed, the wax is injected into the cavity under the conditions of a mold closing pressure of 50MPa-100MPa, an injection pressure of 0.6MPa-1MPa, a wax temperature of 60℃-70℃ and a wax injection time of 5-8s.

[0058] After the wax material is injected, the slots inside the upper cavity and the lower cavity (used to make the shape of a single-body crowned blade) are formed into a blade wax mold according to the shape of the mold.

[0059] Mold opening process

[0060] After the wax injection is completed, the equipment enters the automatic mold opening program.

[0061] Firstly, the upper mold plate drives the upper core-pulling inclined section to perform upper mold core-pulling. The structural design of the upper core-pulling straight section and the upper core-pulling inclined section enables them to be pulled out from the interference hole of the cavity, and the demolding interference position is processed to avoid damage to the wax mold during demolding.

[0062] Next, the upper mold is opened, and the upper mold inclined guide column drives the slider (including the leaf crown slider, etc.) to open the mold, so that the wax model is separated from the mold.

[0063] Finally, the ejection mechanism ejects the blade wax model from the device cavity.

[0064] Wax pattern removal stage

[0065] After the equipment automatically ejects the two blade wax models, the wax models can be taken out manually or by a robotic arm and placed in a wax model storage device for standby use.

[0066] Cooling water circuit function

[0067] During the entire wax model manufacturing process, the cooling water channels in the upper and lower mold bases continue to work. The cooling water enters the water channel through the water inlet on the side wall, expands in an S shape along the long side inside the upper and lower cavities, and finally flows out from the side wall.

[0068] The cooling water circuit effectively controls the mold temperature, making the temperature of the wax model uniform during the manufacturing process, improving the dimensional consistency of the wax model and ensuring the quality of the wax model.
