Detailed Embodiment

[0025] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly.

[0027] As Figures 1 to 3 shown, a general mold plate for casting a fan hub includes a template body 100, positioning pins 200, fixing grooves 300, mounting holes 400, and positioning members 500.

[0028] As Figures 1 to 3 shown, a general mold plate for casting a fan hub includes:

[0029] The template body 100 is used to carry the mold body 600, and the mold body 600 has a positioning hole 700 and a connecting groove 800;

[0030] The positioning assembly includes several groups of positioning pins 200 and fixing grooves 300 provided on the template body 100. The positioning pins 200 form a plug-in fit with the positioning holes 700. The fixing grooves 300 correspond to the connecting grooves 800 and horizontally extend in a direction away from the center line of the template body 100 and extend to communicate with the outside. When a fastener (not shown in the figure) moves along the length direction of the fixing groove 300 and is inserted into the connecting groove 800, the template body 100 and the mold body 600 can be detachably connected. This design allows the fastener to be inserted into the fixing groove 300 and the connecting groove 800 from the side of the template body 100, realizing the quick positioning and detachable connection of the template body 100 and the mold body 600. This not only improves the versatility of the template body 100, reduces the number of template bodies 100 required for different types of hubs, but also simplifies the mold assembly process and effectively improves the assembly efficiency of the template body 100 and the mold body 600.

[0031] Specifically, as Figures 1 to 3 shown, in this embodiment, the template body 100 is rectangular and is used to carry the mold body 600. It is composed of a plurality of rectangular sub-boards 110 spliced together, and the sub-boards 110 are detachably connected to each other. Compared with the traditional integrally formed template body 100, the template body 100 can be stored in blocks, effectively improving the convenience of storage and transportation of the template body 100.

[0032] In this embodiment, there are four sub-boards 110. Each side wall of the sub-board 110 facing away from the mold body 600 has several groups of mounting holes 400. After multiple sub-boards 110 are spliced, the mounting holes 400 on adjacent two sub-boards 110 are coaxially arranged, and the sub-boards 110 can be detachably connected through bolts (not shown in the figure), effectively ensuring the convenience and reliability of the connection between the sub-boards 110.

[0033] Preferably, in this embodiment, each group of mounting holes 400 is composed of four mounting holes 400 arranged in a matrix, and five groups of mounting holes 400 are arranged along the length direction on both side edges of each sub-board 110, further ensuring the stability of the connection between the sub-boards 110.

[0034] In this embodiment, the template body 100 further includes several positioning grooves 410 and pins (not shown in the figure) provided on the sub-board 110. The positioning grooves 410 are arranged adjacent to the mounting holes 400. After multiple sub-boards 110 are spliced, the pins are detachably clamped in the positioning grooves 410 of two relatively arranged sub-boards 110 and pre-fix the two sub-boards 110. This design enables the sub-boards 110 to form a preliminary fixation after splicing, improving the convenience of fixing bolts in the mounting holes 400.

[0035] To achieve the bearing of the mold body 600, the template body 100 is usually placed horizontally, and the mold body 600 is detachably placed on the template body 100, which makes the traditional connection method of passing fasteners through the template body 100 and the mold body 600 from bottom to top have the problem of inconvenient actual operation.

[0036] To improve the convenience when connecting the template body 100 and the mold body 600, in this embodiment, a positioning component is also provided. The positioning component includes several groups of positioning pins 200 and fixing grooves 300 provided on the template body 100. The positioning pins 200 form a plug-in fit with the positioning holes 700 on the mold body 600 for quickly positioning the placement position of the mold body 600. The fixing grooves 300 correspond to the connection grooves 800 on the mold body 600 and extend in a direction away from the center line of the template body 100 and extend to communicate with the outside, so that fasteners can be inserted into the fixing grooves 300 and the connection grooves 800 from the side of the template body 100, enabling the template body 100 to be conveniently connected to the mold body 600 when placed horizontally on the ground. This not only reduces the requirement for the operation space when assembling the template body 100 and the mold body 600, improves the convenience during connection, but also effectively improves the efficiency of assembling the template body 100 and the mold body 600.

[0037] In this embodiment, the fixing groove 300 is an inverted T-shaped groove. The fastener (not shown in the figure) includes a stud whose one end is movably snapped into the fixing groove 300 and the other end sequentially passes through the fixing groove 300 and the connecting groove 800, and a nut detachably provided on the side of the connecting groove 800 away from the fixing groove 300. Through the cooperation of the stud and the nut, the detachable connection between the template body 100 and the mold body 600 can be realized. This design makes the fastener easy to operate, reduces the trouble for the operator to pass through from below the bottom plate, improves the assembly efficiency, and at the same time ensures the stability of the connection between the template body 100 and the mold body 600. In addition, the detachable connection between the template body 100 and the mold body 600 effectively improves the reuse rate of the template body 100.

[0038] In this embodiment, several groups of positioning pins 200 and fixing grooves 300 are respectively arranged circumferentially along the center line of the template body 100, and both are in a Y shape. Among them, there is a gap between the positioning pin 200 and the fixing groove 300. The design of these multiple groups of positioning pins 200 and fixing grooves 300 effectively increases the connection points between the template body 100 and the mold body 600. On the one hand, it ensures the stability of the connection between the two, and on the other hand, it can also adapt to the connection requirements of different models of mold bodies 600; and by leaving a gap between the positioning pin 200 and the fixing groove 300, interference between the two during the assembly process is effectively avoided.

[0039] In this embodiment, each group of positioning pins 200 is composed of five positioning pins 200. The five positioning pins 200 are arranged in a straight line in the direction away from the center line of the mold body 600, and there is a gap between adjacent two positioning pins 200. This design enables the template body 100 to position different-sized mold bodies 600, effectively improving the versatility of the template body 100.

[0040] In this embodiment, each group of fixing grooves 300 is composed of three fixing grooves 300, and the three fixing grooves 300 are arranged at equal intervals. This design further increases the connection points between the template body 100 and the mold body 600, enabling the template body 100 to form a detachable connection with different-sized mold bodies 600, and effectively improving the versatility of the template body 100.

[0041] It should be noted that, in this embodiment, the fixing groove 300 and the positioning pin 200 are respectively provided on the sub-board 110. Among them, after the sub-boards 110 are spliced, each fixing groove 300 can be kept in a state of extending to communicate with the outside.

[0042] In this embodiment, a plurality of adjusting plates 111 are further provided on the side of the template body 100 facing away from the mold body 600. An adjusting hole 112 penetrating through itself is provided on the adjusting plate 111. Preferably, the adjusting hole 112 is a threaded hole, so that the user can set bolts (not shown in the figure) as needed and adjust the height of the adjusting bolts. This design enables the template to be placed stably on an uneven ground by adjusting the heights of the bolts in the adjusting holes 112 at different positions.

[0043] In this embodiment, a plurality of operation holes 900 are further provided on the template body 100. The operation holes 900 penetrate through the template body 100, and communicate the adjusting holes 112, the mounting holes 400 with the side of the template body 100 facing the mold body 600. Thus, the user can conveniently perform operations such as tightening bolts or adjusting bolts through the operation holes 900. Preferably, a detachable cover plate 910 is provided on each operation hole 900, and the cover plate 910 is used to ensure the flatness of the surface of the split plate 110.

[0044] In this embodiment, a plurality of groups of positioning members 500 for positioning the sprue are further provided on the side of the template body 100 facing the mold body 600. Each group of positioning members 500 is composed of three positioning members 500. Each positioning member 500 is in a circular convex shape, and there is a gap between the three positioning members 500. This design helps to ensure the accurate position of the sprue during the casting process and improves the casting accuracy.

[0045] As Figures 1 to 7 shown, the embodiment of the present invention further provides a casting mold for a fan hub including the above-mentioned general mold template, which includes:

[0046] A mold body 600, in which a steel frame 610 is provided, and a plurality of positioning holes 700 and connecting grooves 800 are provided on the steel frame 610;

A plurality of groups of positioning pins 200 and fixing grooves 300 are provided on the template body 100. The positioning pins 200 form a plug-in fit with the positioning holes 700. The fixing grooves 300 correspond to the connecting grooves 800 and horizontally extend in a direction away from the center line of the template body 100 and extend to communicate with the outside. When a fastener (not shown in the figure) moves along the length direction of the fixing groove 300 and is caught in the connecting groove 800, the template body 100 and the mold body 600 can be detachably connected. Through the detachable connection design of the template body 100 and the mold body 600, the rapid installation and disassembly of the mold are realized, which improves the assembly efficiency and the utilization rate of the template body 100 at the same time.

[0048] In this embodiment, the connecting groove 800 is a horizontally arranged U-shaped groove, whose opening faces away from the center line of the mold body 600, and a thickening portion 810 adapted to the connecting groove 800 is provided in the connecting groove 800. The fixing groove 300 is an inverted T-shaped groove. The fastener includes a stud whose one end can be movably inserted into the fixing groove 300 and the other end sequentially passes through the fixing groove 300 and the connecting groove 800, and a nut detachably arranged on the side of the thickening portion 810 away from the fixing groove 300. Through the cooperation of the stud and the nut, the detachable connection between the template body 100 and the mold body 600 can be realized. This design effectively improves the strength of the connecting groove 800, and through the cooperation with the fixing groove 300 and the fastener, the connection between the mold body 600 and the template body 100 is more stable and reliable.
