Description

Technical Field

[0001] The utility model relates to the technical field of mold opening equipment, in particular to a curved mold opening mechanism for a blade body block of a turbine rotor wax mold. Background Art

[0002] At present, turbine rotor wax molds are basically designed and manufactured according to the structure of the faceplate driving the slider. During the use of the mold, you only need to hold the mold opening handle and rotate it directly around the center of the circle, and the entire slider will open at the same time to complete the mold opening action. Then you can take out the product, which basically meets the above requirements.

[0003] The special turbine rotor wax mold also uses a disc-driven slider structure. Due to the special product, the slider cannot be molded along a straight line or arc trajectory. The original slider needs to be made into two pieces, and the mold can only be opened by sliding in different directions. However, this structure has obvious disadvantages, as follows:

[0004] The current structure requires doubling the number of original sliders when pressing special turbine rotors, which results in a complex mold structure, a long processing cycle, and high processing costs, thus affecting efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the above-mentioned prior art and provide a curved mold opening mechanism for a blade body block of a turbine rotor wax mold.

[0006] The technical scheme of the utility model is: a curved mold opening mechanism for a blade body block of a turbine rotor wax mold, comprising a bottom plate with a material ejection mechanism at the center of the upper end, a faceplate arranged at the upper end of the bottom plate and located at the periphery of the material ejection mechanism, a lower mold block located at the upper end of the faceplate and connected to the four corners of the bottom plate at the bottom end, and a mold opening assembly arranged on the lower mold block;

[0007] The upper end of the faceplate is evenly provided with a plurality of arc-shaped sliding grooves along the circumferential direction, the side wall of the faceplate is provided with a faceplate handle extending to the outside, and the lower model block is provided with a plurality of sliding grooves distributed in a divergent shape, and a mounting groove is provided on one side of each sliding groove;

[0008] The mold opening assembly includes a slider arranged on the lower model block and corresponding to the sliding groove one by one, a fixed block connected to the outer wall of the slider through a rotating shaft, an L-shaped guide rail whose vertical section is arranged on the rotating shaft and connected to the fixed block and whose horizontal section is slidably connected to the sliding groove, a guide block arranged in the mounting groove and having a curved sliding groove at the upper end, a roller bearing arranged at the bottom end of the slider and slidably connected to the curved sliding groove, and a sliding column slidably connected to the arc-shaped sliding groove at the bottom end of the horizontal section of the L-shaped guide rail.

[0009] Furthermore, the four corners of the upper end of the lower model block are provided with mounting circular openings, a mounting guide sleeve is provided in the mounting circular opening, a guide rod is provided at the upper end of the mounting guide sleeve, a clamping block is provided at the upper end of the lower model block, and a through positioning opening corresponding to the guide rod is provided on the clamping block.

[0010] Note: When installing the clamping block, align the through positioning holes on the upper end of the clamping block with the corresponding guide rods one by one and position it to the upper end of the lower model block through the guide rods. The guide rods provide guidance and positioning for the installation of the lower model block to ensure accurate installation of the clamping block and avoid displacement of the clamping block during transportation.

[0011] Furthermore, the clamping block is penetrated by a plurality of fixing screw rods connected to the upper end of the lower mold block.

[0012] Note: After the clamping block is installed on the upper end of the lower mold block, fix the clamping block by fixing the screw rod to improve the compactness of the clamping block installation. When opening the mold, the clamping block can be removed by fixing the screw rod.

[0013] Furthermore, a soft rubber protective cover is provided on the faceplate handle and located outside the bottom plate and the lower model block.

[0014] Note: When the staff holds the faceplate handle, the soft rubber protective cover can prevent the hand from slipping, improve the touch of the faceplate handle, and increase the comfort of operation.

[0015] Furthermore, a clamping notch is provided at the bottom end of the faceplate, and one end of the faceplate handle is connected to the clamping notch by a bolt.

[0016] Note: Connect the faceplate and the faceplate handle with bolts to facilitate the disassembly and installation of the faceplate handle.

[0017] The working principle of the utility model is:

[0018] When opening the mold, the staff holds the faceplate handle and rotates it counterclockwise, while each sliding column slides outward in the corresponding arc-shaped sliding groove synchronously. At this time, the roller bearing slides along the curved groove, driving the corresponding slider to rotate around the rotation axis and move obliquely toward the L-shaped guide rail, so that each slider is detached from the turbine product, completing the mold opening action of the slider. After the mold opening is completed, take out the product, hold the faceplate handle and rotate it clockwise, each sliding column moves in the opposite direction in the corresponding arc-shaped sliding groove, and the corresponding slider rotates in the opposite direction around the rotation axis and moves away from the L-shaped guide rail, so that each slider closes with each other. During the closing process, each slider is reset to the mold closing position.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] When the curved mold opening mechanism of the utility model is used, the slider is disengaged and at the same time, it is driven to move in an inclined direction so that the slider is pulled out of the turbine product, thereby avoiding interference between the slider and the turbine blades during the slider disengagement process. This avoids the problem that the existing mold opening mechanism needs to double the number of sliders when pressing special turbine rotors, resulting in a complex mold structure and a long processing time cycle. The curved mold opening mechanism has the advantages of simple structure, easy operation, short processing cycle, and easy manufacturing and maintenance without increasing the number of sliders. The pressed products have good consistency and stable shape, and are suitable for large-scale promotion. BRIEF DESCRIPTION OF THE DRAWINGS
