Technical Field
[0001] This utility model relates to the field of engine component processing technology, and in particular to an angle-adjustable double-column thin-walled core support. Background Technology
[0002] A double-column thin-walled core brace is a metal component used to support the sand core or part of the sand mold during sand mold assembly. It is characterized by having two support columns and a relatively thin wall structure. When using a double-column thin-walled core brace, it is necessary to ensure that its contact surface with the sand core or sand mold is flat and smooth to reduce friction and resistance.
[0003] With the rapid development of technology, the automotive industry has also been developing rapidly in recent years. Cars are driven by engines, which convert gasoline into mechanical energy to provide power for the car. Engine blocks are mostly made of cast metal parts because of their good mechanical properties and high temperature resistance. During the casting process of engine blocks, core supports are needed to support the sand core and keep it in the correct position within the mold cavity.
[0004] The above-mentioned defects are as follows: the cavity wall needs to be supported by a core support, but it is only supported by a horizontal surface, resulting in gaps on the inclined surface. When the core support melts during casting, air bubbles are easily generated in the cavity, which affects the casting quality of the generator cylinder. To solve the above problems, an angle-adjustable double-column thin-walled core support is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an angle-adjustable double-column thin-walled core support, which aims to improve the problem in the prior art where the cavity wall needs core support, but only the horizontal surface is supported, resulting in gaps on the inclined surface. When the core support melts during casting, the cavity is prone to generating air bubbles in the casting.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an angle-adjustable double-column thin-walled core support, comprising a double-column support body and a support column, wherein an adjustment mechanism is provided on the support column, and a limit mechanism is provided on the double-column support body. The adjustment mechanism includes a rotating rod, which is rotatably connected to the inner walls of the top and bottom sides of the support column via bearings. An adjustment plate is fixedly connected to the rotating rod, and a support plate is fixedly connected to the left outer wall of the adjustment plate. A limit hole is opened on the top inner wall of the support column, and a shaft disk is slidably connected to the top inner wall of the support column. A limit column is fixedly connected to the bottom outer wall of the shaft disk, and a threaded disk is rotatably connected to the top outer wall of the shaft disk via bearings.
[0007] As a further description of the above technical solution: the limiting mechanism includes a slide rail, which is opened on the top inner wall of the double column support body. The inner walls on both sides of the slide rail are slidably connected to abutment plates. The top inner wall of the abutment plates is slidably connected to a large arc plate. The rear outer wall of the large arc plate is fixedly connected to a compression spring. A latch is opened on one side inner wall of the slide rail.
[0008] As a further description of the above technical solution: upright plates are fixedly connected to the four outer walls of the adjusting plate, and the outer wall of the upright plate away from the adjusting plate is fixedly connected to the outer wall of the supporting plate on one side.
[0009] As a further description of the above technical solution: the limiting hole is opened on the top inner wall of the adjusting plate, and the limiting post penetrates the inner wall of the limiting hole.
[0010] As a further description of the above technical solution: the threaded disc is threadedly connected to the top inner wall of the support column, and an indicator mark is provided on the top outer wall of the threaded disc.
[0011] As a further description of the above technical solution: the compression spring penetrates the inner wall of one side of the abutment plate, and the end of the compression spring away from the large arc plate is fixedly connected to the inner wall of one side of the slide.
[0012] As a further description of the above technical solution: the large arc plate is slidably connected to one side of the outer wall of the small arc plate, the small arc plate penetrates one side of the outer wall of the abutment plate, and the small arc plate is engaged with the inner walls on both sides of the slot.
[0013] As a further description of the above technical solution: a second support plate is fixedly connected to one end of the dual-column support body away from the support column, and the support column is threadedly connected to the inner wall of the inner ring of the dual-column support body.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, by setting an adjustment plate, a vertical plate, and a limiting hole structure, the support plate is prevented from bending when supporting the inner wall of the engine cylinder, and the fitting angle of the support plate is adjusted and adapted. This improves the problem that the cavity wall needs core support, but only horizontal support is available, resulting in gaps on the inclined surface. When casting, the cavity is prone to generating air bubbles in the casting, thus affecting the casting quality of the generator cylinder.
[0016] 2. In this utility model, by setting up structures such as small arc plates, bayonets, and abutment plates, the support columns are prevented from rotating and shrinking, thus preventing the support components from malfunctioning and causing the engine cylinder block to lack support during casting, which would affect the quality of engine cylinder block casting.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an angle-adjustable double-column thin-walled core support, comprising a double-column support body 1 and a support column 2. An adjustment mechanism 3 is provided on the support column 2, and a limiting mechanism 4 is provided on the double-column support body 1. The adjustment mechanism 3 includes a rotating rod 31, which is rotatably connected to the inner walls of the top and bottom sides of the support column 2 via bearings. An adjustment plate 32 is fixedly connected to the rotating rod 31. The angle of the support plate 35 is adjusted by the adjustment plate 32. The support plate 35 is fixedly connected to the left outer wall of the adjustment plate 32, supporting the inner wall of the engine cylinder block. A limiting hole 36 is opened on the top inner wall of the support column 2. A shaft disc 37 is slidably connected to the top inner wall of the support column 2. A limiting post 38 is fixedly connected to the bottom outer wall of the shaft disc 37, limiting the limiting hole 36 by the limiting post 38. A threaded disc 39 is rotatably connected to the top outer wall of the shaft disc 37 via bearings.
[0025] Reference Figure 2 - Figure 4 The four outer walls of the adjusting plate 32 are fixedly connected with upright plates 34. The outer wall of the upright plates 34 away from the adjusting plate 32 is fixedly connected to the outer wall of the support plate 35. The upright plates 34 provide tilt support for the support plate 35 to prevent bending. The limiting hole 36 is opened on the top inner wall of the adjusting plate 32. The limiting post 38 penetrates the inner wall of the inner ring of the limiting hole 36. The threaded plate 39 is threadedly connected to the top inner wall of the support post 2. The top outer wall of the threaded plate 39 is provided with an indicator mark to indicate the operation method. The end of the double column support body 1 away from the support post 2 is fixedly connected with a second support plate 5. The support post 2 is threadedly connected to the inner wall of the inner ring of the double column support body 1.
[0026] Reference Figure 3 - Figure 4 The limiting mechanism 4 includes a slide rail 41, which is located on the top inner wall of the double-column support body 1. Abutment plates 42 are slidably connected to the inner walls of both sides of the slide rail 41. By setting the abutment plates 42 to abut the column support 2, the rotation and retraction of the column support 2 are prevented, thus preventing loosening of the support plate 35 inside the engine cylinder block. A large arc plate 43 is slidably connected to the top inner wall of the abutment plate 42. By setting the large arc plate 43 to compress the small arc plate 45, a compression device is fixedly connected to the rear outer wall of the large arc plate 43. A spring 44 is provided. A slot 46 is provided on one side of the inner wall of the slide 41. The compression spring 44 passes through one side of the inner wall of the abutment plate 42. The end of the compression spring 44 away from the large arc plate 43 is fixedly connected to one side of the inner wall of the slide 41. By setting the compression spring 44, the large arc plate 43 and the abutment plate 42 are pushed to move. The large arc plate 43 is slidably connected to one side of the outer wall of the small arc plate 45. The small arc plate 45 passes through one side of the outer wall of the abutment plate 42. The small arc plate 45 is engaged with the inner walls on both sides of the slot 46.
[0027] Working principle: By rotating the support column 2, it extends out from the double-column support body 1. Then, the support plate 35 is adjusted to attach to the inside of the engine cylinder block with different slopes. Then, the threaded plate 39 is rotated and fixed to the top of the support column 2 by threads. At the same time, the shaft plate 37 is driven to move downward so that the limiting column 38 is inserted into the limiting hole 36. Then, the limiting column 38 passes through the limiting hole 36 on the adjusting plate 32, limiting and fixing the angle of the adjusting plate 32. At the same time, after the distance and angle between the inner walls of the engine cylinder are adjusted, the double-column support is retracted to prevent the support column 2 from rotating. When the support column 2 extends outward from the double-column support body 1, the compression spring 44 continuously pushes the large arc plate 43 and the abutment plate 42 to move. The movement of the large arc plate 43 pushes the small arc plate 45 to move. Because of the front arc surface of the small arc plate 45, it will slide out from the slot 46, causing the abutment plate 42 to move outward with the support column 2. When the support column 2 rotates and retracts, one end of the support column 2 contacts the abutment plate 42. The abutment plate 42 is engaged in the corresponding slot 46 on the rear vertical surface of the small arc plate 45 to prevent the support column 2 from rotating and retracting.
[0028] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
