An inclined guide assembly 9 is also provided on one side of the upper mold base 3, and a blade crown slider assembly 10 is also provided on one side of the end of the upper mold base 9.

[0041] The overall shape of the lower mold base 4 is consistent with that of the upper mold base 3.

A blade crown slider assembly 10 is also provided on one side of the end of the upper mold base.

[0042] The inclined guide assembly 9 includes an upper guide seat 91 and a lower guide seat 92 which are respectively abutted against the upper mold base and the lower mold base. An inclined guide column 93 is provided in the lower guide seat, and an inclined slider 94 is provided in the upper guide seat. The inclined slider 94 is sleeved on the inclined guide column 93; the end of the inclined slider extends into the upper mold cavity and the lower mold cavity and abuts against one side of the leaf crown.

[0043] The leaf crown slider assembly 10 includes an upper inclined guide column 10a fixed to the upper mold base, a second inclined slider 10b is sleeved on the outer portion of the upper inclined guide column, and a leaf crown slider 10c is abutted against the second inclined slider.

[0044] The upper core pulling part is internally divided into an upper core pulling straight section 71 and an upper core pulling inclined section 72 , and the upper core pulling part is obliquely inserted into the interference hole 82 of the upper cavity.

[0045] The structure of the water channel 12 is as follows: a water channel inlet 12a is provided on the side wall of the upper mold base. The water channel 12 extends into the interior of the upper mold base 3 and then extends downward into the interior of the upper mold cavity 8. The water channel 12 continues to extend along the long side of the upper mold cavity 8. The internal water channel of the upper mold cavity is generally S-shaped, and the water channel opens to the side wall of the upper mold base 3 at the end.

[0046] A water inlet 12a is provided on the side wall of the lower mold base 4. The water channel 12 extends toward the interior of the lower mold base 4 and then extends downward to the interior of the lower cavity 11. The water channel continues to expand along the long side of the lower cavity 11. The internal water channel of the lower cavity 11 is S-shaped as a whole, and the water channel leads to the side wall of the lower mold base 4 at the end.

[0047] The number of the upper mold cavities is two, and the number of the lower mold 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] Mold closing 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] During this process, the oblique guide assembly comes into play. The upper and lower guide seats abut against the upper and lower mold bases respectively. The oblique guide post in the lower guide seat cooperates with the oblique slide sleeved on it in the upper guide seat to ensure the precise movement of all components 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 mold cavity under the conditions of mold closing pressure of 50MPa-100MPa, injection pressure of 0.6MPa-1MPa, wax temperature of 60℃-70℃ and wax injection time of 5-8s.

[0058] After the wax is injected, the slots inside the upper cavity and the lower cavity (used to make the shape of a single 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] First, the upper template 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, processing the demoulding interference position to avoid damage to the wax mold during demoulding.

[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, separating the wax model from the mold.

[0063] Finally, the ejection mechanism ejects the blade wax mold 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 later use.

[0066] Function of cooling water channel

[0067] Throughout the wax model manufacturing process, the cooling water circuits in the upper and lower mold bases operate continuously. Cooling water enters the circuits through the water inlets on the side walls, expands in an S-shape along the long sides of the upper and lower cavities, and finally flows out through the side walls.

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