Description

Technical Field

[0001] This utility model relates to the field of impeller technology, and in particular to a demolding mechanism for an impeller mold. Background Technology

[0002] In the mold manufacturing industry, demolding of impeller molds is a crucial step. Traditional demolding methods, such as top-and-bottom demolding or straight-slide demolding, are ineffective when dealing with impellers with complex blade curvatures. To meet demolding requirements, a circular arc-shaped sliding block is typically used. However, the drive system for this type of sliding block is extremely complex. It involves a hydraulic cylinder driving a rack, which then drives a large gear ring via gears. The large gear ring then drives six small gears, which ultimately drive the arc-shaped sliding block. This complex drive system not only increases the manufacturing difficulty of the impeller mold but also significantly raises its production cost. Utility Model Content

[0003] In view of this, and to solve the above problems, the purpose of this utility model is to provide a demolding mechanism for an impeller mold, used for impeller demolding, comprising:

[0004] A rotating slider that is rotatably disengaged from the impeller;

[0005] A slider support base is provided at one end of each of the rotating sliders;

[0006] Each of the aforementioned slider supports is rotatably connected to one end of one of the aforementioned links;

[0007] A straight-moving slider seat, wherein the straight-moving slider seat is rotatably connected to the other end of the connecting rod;

[0008] The slide rail has a linear slider seat disposed inside it and slidably connected to it.

[0009] In another preferred embodiment, the impeller includes: blades, a base plate, and a bearing. The base plate has a rotating hole at its center, and the bearing is disposed in the rotating hole. A plurality of blades are spaced apart on the base plate, and each blade extends spirally from the inside to the outside of the base plate.

[0010] In another preferred embodiment, the rotating slider is disposed between two adjacent blades.

[0011] In another preferred embodiment, two adjacent slider supports are at different heights.

[0012] In another preferred embodiment, a connecting hole is provided on one side of the slider support, and a first rotating shaft is provided in the connecting hole. One end of the connecting rod is rotatably connected to the slider mounting base through the first rotating shaft.

[0013] In another preferred embodiment, a rotating hole is provided on the other side of the slider support, and a second rotating shaft is provided in the rotating hole, so that the rotating slider can rotate about the second rotating shaft as the center of rotation.

[0014] In another preferred embodiment, the straight slider seat is connected to an external inclined guide post.

[0015] The present invention, by adopting the above-mentioned technical solution, has the following positive effects compared with the prior art: By applying the present invention, a demolding mechanism for impeller molds is proposed. This mechanism uses inclined guide pillars to drive a rotating slider, eliminating the need for hydraulic pump stations and hydraulic and rack-and-pinion drive methods. This simplifies the drive system and drive method, thereby reducing the manufacturing difficulty and production cost of impeller molds and improving their production efficiency. During the demolding process, the coordinated operation of the inclined guide pillars and the rotating slider ensures a uniform force on the blades, thus improving the product quality of the impeller molds. Furthermore, the simplification of the drive system and drive method also reduces the floor space required for the drive system, making the spatial layout more compact and rational.

[0025] like Figure 1-4 The diagram illustrates a preferred embodiment of a demolding mechanism for an impeller mold, used for demolding the impeller 1, comprising:

[0026] Rotary slider 2, which can be rotatably disengaged from impeller 1;

[0027] Slider support 3, one end of each rotating slider 2 is provided with a slider support 3;

[0028] Link 4, each slider support 3 is rotatably connected to one end of a link 4, the link 4 is used to convert the linear motion of the straight slider seat 5 into the rotational motion of the rotating slider 2;

[0029] The straight-moving slider seat 5 is rotatably connected to the other end of the connecting rod 4;

[0030] The slide rail 6 and the straight slider seat 5 are disposed inside the slide rail 6 and are slidably connected to the slide rail 6. The slide rail 6 is used to provide precise guidance for the linear movement of the straight slider seat 5 to ensure the straightness and stability of the movement of the straight slider seat 5.

[0031] Furthermore, as a preferred embodiment, the impeller 1 includes: blades 11, a base plate 12 and a bearing 13. A rotating hole is provided in the center of the base plate 12, and the bearing 13 is disposed in the rotating hole. A plurality of blades 11 are arranged at intervals on the base plate 12, and each blade 11 extends spirally from the inner side to the outer side of the base plate 12.

[0032] Furthermore, in a preferred embodiment, the rotating slider 2 is disposed between two adjacent blades 11. Furthermore, the rotating slider 2 can provide uniform support force to the blades 11 during demolding, avoiding damage to the blades 11.

[0033] Furthermore, as a preferred embodiment, the two adjacent slider supports 3 are at different heights to avoid interference between the two adjacent slider supports 3 during movement.

[0034] Furthermore, as a preferred embodiment, a connecting hole is provided on one side of the slider support 3, and a first rotating shaft 31 is provided in the connecting hole. One end of the connecting rod 4 is rotatably connected to the slider mounting base through the first rotating shaft 31.

[0035] Furthermore, as a preferred embodiment, a rotating hole is provided on the other side of the slider support 3, and a second rotating shaft 32 is provided in the rotating hole, so that the rotating slider 2 can rotate around the second rotating shaft 32 as the rotation center.

[0036] Furthermore, in a preferred embodiment, the linear slider seat 5 is connected to an external inclined guide post. The inclined guide post further serves to drive the linear slider seat 5 to slide along the slide rail 6.

[0037] The working principle of this utility model is as follows: When demolding the impeller 1, the demolding mechanism first enters the position specified in the instruction manual. Figure 2 The mold is closed as shown. Then, the straight slide block 5 is driven by the inclined guide post to move along the slide rail 6 away from the impeller 1. When the straight slide block 5 moves linearly along the slide rail 6, since one end of the connecting rod 4 is rotatably connected to the slide block support 3 through the first rotating shaft 31, and the other end of the connecting rod 4 is rotatably connected to the straight slide block 5, the linear movement of the straight slide block 5 will drive the connecting rod 4 to move. The movement of the connecting rod 4 will then pull the slide block support 3. Since the slide block support 3 is rotatably connected to the rotating slide block 2 through the second rotating shaft 32, the movement of the slide block support 3 will drive the rotating slide block 2 to move, so that the rotating slide block 2 rotates around the second rotating shaft 32 as the center of rotation. During the rotation, the rotating slide block 2 will gradually disengage from the two adjacent blades 11, thereby realizing the demolding of the impeller 1. At this time, the demolding mechanism is in the position specified in the instruction manual. Figure 1 The mold opening state is shown.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
