Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to a large parts casting mold for uniform casting. Background Technology

[0002] In the actual production process of wind power generation equipment, many internal components are used. Most of these components need to be produced by injection molding, which requires the use of injection molds.

[0003] For example, Chinese utility model patent with announcement number CN217196606U discloses a processing mold for wind power equipment parts in the field of wind power, including a processing base, a mold placement platform rotatably mounted on the processing base via a rotating shaft, multiple mold lower shells placed on the mold placement platform, and an upper mold shell above each of the multiple mold lower shells.

[0004] In the above solution, although the upper shell of the mold can be moved from the lower shell of the mold to the upper shell of the mold by the telescopic motor to realize the production of parts, and the filling block can be moved by the push motor to push out the molded parts and realize demolding, the telescopic motor and the push motor need to be installed in each group of production equipment, which makes the overall cost of the equipment too high. Furthermore, it cannot be guaranteed that multiple telescopic motors and push motors will operate continuously and synchronously. As long as there is a slight deviation, there will be differences in the parts of this batch. Utility Model Content

[0005] To address the issue of excessively high overall equipment costs due to the installation of telescopic and push motors in each production unit, and the inability to guarantee continuous synchronous operation of multiple telescopic and push motors, which can lead to technical issues with differences in parts even with slight deviations, this invention provides a casting mold for large parts that allows for uniform casting.

[0006] This utility model is achieved using the following technical solution: a large part casting mold for uniform casting, comprising a base, a fixed column fixedly connected to the top of the base, a base plate fixedly connected to the top of the fixed column, a plurality of lower mold shells arranged in a circular pattern fixedly connected to the top of the base plate, an upper mold shell disposed above the lower mold shells, a servo motor fixedly connected to the middle of the top of the base, a central shaft fixedly connected to the output end of the servo motor, the central shaft being rotatably connected to the middle of the base plate, a connecting component for moving the plurality of upper mold shells being disposed on the outer side of the central shaft, a limiting component being disposed between the upper mold shells and the lower mold shells, and a moving component for ejecting the part for demolding being disposed at the bottom of the base plate.

[0007] Through the above technical solution, the rotation of the servo motor enables the connecting component to drive multiple upper mold shells to move downward synchronously. By limiting the limit component, the upper and lower mold shells are completely merged, allowing the parts inside the mold shells to be shaped. At this time, the servo motor is turned on to reverse and drive the upper mold shells to move upward, so that the moving component fixed to the upper mold shell slides synchronously in the slide groove, driving the top column inside the lower mold shell to eject the shaped parts, thus achieving demolding.

[0008] As a further improvement to the above solution, the connecting assembly includes a connecting block that can move up and down and is installed on the outside of the central axis, and multiple upper mold shells are fixed to the outside of the connecting block.

[0009] As a further improvement to the above solution, the central shaft is provided with a reciprocating thread on the outer side of the top of the base plate, and the middle part of the connecting block is connected to the reciprocating thread.

[0010] Through the above technical solution, a reciprocating thread is provided on the outer side of the central shaft, so that the rotation of the central shaft can drive the connecting block connected to the outer side of the reciprocating thread to move up and down, thereby enabling multiple upper modules to move synchronously.

[0011] As a further improvement to the above solution, the limiting component includes a limiting post fixed to the top edge of the lower mold shell, and a limiting hole for sliding of the limiting post is provided on the bottom edge of the upper mold shell.

[0012] Through the above technical solution, the limiting hole opened in the upper mold shell and the limiting post fixed to the lower mold shell can limit the upper mold shell and the lower mold shell when they are closed, so as to avoid the displacement during the extrusion process and the resulting deviation of the produced parts.

[0013] As a further improvement to the above solution, the moving component includes five top pillars that slide on the top plate and the lower mold shell. The bottom ends of the five top pillars are fixedly connected to a connecting plate. A linkage component is provided between the connecting plate and the upper mold shell. The linkage component includes a top plate fixedly connected to the upper mold shell. A connecting pillar is fixedly connected between the top plate and the connecting plate. A sliding groove is provided on the bottom plate. The connecting pillar is slidably connected in the sliding groove. The five top pillars abut against the four sides and the center point of the bottom end of the part.

[0014] With the above technical solution, after the upper mold shell is shaped, it will simultaneously drive the connecting column to slide upward inside the slide groove. At this time, the connecting plate fixed to the bottom of the connecting column will move upward simultaneously, and will also drive the five top columns to move upward, thus demolding the parts inside the lower mold shell.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes the rotation of a servo motor to enable the connecting assembly to drive multiple upper mold shells to move downwards synchronously, achieving simultaneous processing of multiple parts and improving equipment production efficiency. Furthermore, the limiting assembly ensures that the upper and lower mold shells are completely merged, allowing for the shaping of parts inside the mold shells. At this point, the servo motor reverses, driving the upper mold shells upwards, causing the moving assembly fixed to the upper mold shells to slide synchronously within the groove. This, in turn, causes the ejector pin inside the lower mold shell to push out the shaped parts, achieving demolding. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Please combine Figures 1-4 This embodiment of a casting mold for large parts with uniform casting includes a base 1, a fixed column 2 fixedly connected to the top of the base 1, a base plate 3 fixedly connected to the top of the fixed column 2, a plurality of lower mold shells 4 arranged in a circle fixedly connected to the top of the base plate 3, an upper mold shell 5 arranged above the lower mold shells 4, a servo motor 6 fixedly connected to the middle of the top of the base 1, a central shaft 7 fixedly connected to the output end of the servo motor 6, the central shaft 7 being rotatably connected to the middle of the base plate 3, a connecting component for moving the plurality of upper mold shells 5 on the outer side of the central shaft 7, a limit component between the upper mold shells 5 and the lower mold shells 4, and a moving component for ejecting the parts for demolding at the bottom of the base plate 3.

[0025] The rotation of the servo motor 6 enables the connecting assembly to drive multiple upper mold shells 5 to move downwards synchronously. The limiting assembly restricts the upper mold shell 5 and the lower mold shell 4 to completely merge, allowing the parts inside the mold shell to be shaped. At this time, the servo motor 6 is turned on to reverse and drive the upper mold shell 5 to move upwards, so that the moving assembly fixed to the upper mold shell 5 slides synchronously in the slide groove 15, driving the ejector pin 12 inside the lower mold shell 4 to eject the shaped parts, thus achieving demolding.

[0026] Combination Figure 1 and Figure 2 The connecting assembly includes a connecting block 8 that can move up and down and is installed on the outside of the central shaft 7. Multiple upper mold shells 5 are fixed on the outside of the connecting block 8. The central shaft 7 is provided with a reciprocating thread 9 on the outside of the top of the base plate 3. The middle part of the connecting block 8 is connected to the reciprocating thread 9.

[0027] By providing a reciprocating thread 9 on the outer side of the central shaft 7, the rotation of the central shaft 7 can drive the connecting block 8, which is connected to the outer side of the reciprocating thread 9, to move up and down. The movement of the connecting block 8 can drive the multiple upper mold shells 5, which are fixed to their outer side, to move synchronously, so that the equipment can produce multiple parts at the same time and improve the production efficiency of the equipment.

[0028] Combination Figure 2 and Figure 3 The limiting component includes a limiting post 10 fixed to the top side of the lower mold shell 4, and a limiting hole 11 for sliding of the limiting post 10 is provided on the bottom side of the upper mold shell 5.

[0029] The limiting hole 11 in the upper mold shell 5 and the limiting post 10 fixed to the lower mold shell 4 can limit the upper mold shell 5 and the lower mold shell 4 when they are closed, so as to avoid the displacement during the extrusion process and the resulting deviation of the produced parts.

[0030] Combination Figure 4 The moving component includes five top posts 12 that slide on the top plate 13 and the lower mold shell 4. The bottom ends of the five top posts 12 are fixedly connected to a connecting plate 16. A linkage component is provided between the connecting plate 16 and the upper mold shell 5. The linkage component includes the top plate 13 fixedly connected to the upper mold shell 5. A connecting post 14 is fixedly connected between the top plate 13 and the connecting plate 16. A sliding groove 15 is provided on the bottom plate 3. The connecting post 14 is slidably connected in the sliding groove 15. The five top posts 12 abut against the four sides and the center point of the bottom end of the part.

[0031] By moving the upper mold shell 5, the servo motor 6 is turned on to reverse after the molding is completed. This causes the central shaft 7, which is fixed to the output end of the servo motor 6, to move the connecting block 8 upward in sync. At this time, the limiting post 10 on the lower mold shell 4 will gradually disengage from the slide groove 15 opened by the upper mold shell 5 and will simultaneously drive the connecting post 14 to slide upward inside the slide groove 15. At this time, the connecting plate 16 fixed to the bottom end of the connecting post 14 will move upward in sync, and will also drive the five top posts 12 to move upward, which will abut against the four sides and the middle of the bottom surface of the part inside the lower mold shell 4. Because the surface temperature of the part that has just been demolded is high, it can avoid deformation caused by uneven force when the part is demolded.

[0032] The implementation principle of a large part casting mold for uniform casting in this application embodiment is as follows:

[0033] Before producing parts, multiple initial molds are placed into the multiple lower mold shells 4 at the top of the base plate 3 in sequence. Then, the servo motor 6 at the top of the base 1 is turned on to drive the central shaft 7 to rotate. Since the reciprocating thread 9 is provided on the outer side of the central shaft 7 above the top plate 13, the rotation of the central shaft 7 can drive the connecting block 8 connected to the outer side of the reciprocating thread 9 to move downward, so that multiple upper modules fixed to the outer side of the connecting block 8 move downward synchronously and close with the lower mold shell 4, and perform molding processing on the initial mold inside the lower mold shell 4.

[0034] Before the upper mold shell 5 and the lower mold shell 4 are closed, the limiting post 10 fixed to the top edge of the lower mold shell 4 first slides inside the limiting hole 11 opened at the bottom edge of the upper mold shell 5.

[0035] After the parts processing is completed, the servo motor 6 is turned on to reverse, causing the central shaft 7 to drive the connecting block 8 to move upward. This causes multiple upper mold shells 5 to move upward synchronously and disengage from the lower mold shell 4. At the same time, because the bottom plate 3 fixed to the top of the fixed column 2 has a sliding groove 15, and the connecting column 14 fixed between the top plate 13 and the connecting plate 16 slides inside the sliding groove 15, the top plate 13 fixed to the top of the upper mold shell 5 will drive the connecting plate 16 and the connecting column 14 to move upward synchronously. At this time, the connecting column 14 slides inside the sliding groove 15, and the five top columns 12 sliding on the top plate 13 and the lower mold shell 4 follow the connecting column 14 to move upward, and demold the parts inside the lower mold shell 4.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
