Description

Technical Field

[0001] This utility model relates to the field of engine casting technology, specifically a core support for engine cylinder head casting. Background Technology

[0002] Engine block casting refers to the casting of engine blocks using sand casting technology. During the casting process, a core support is needed to fix the sand mold of the engine block to ensure its wall thickness.

[0003] Existing core supports generally only have two sides and can only support two wall surfaces. If it is necessary to support three or more support surfaces, multiple core supports are required to support and fix them, which reduces the casting quality. Moreover, core supports are generally welded together, and the whole is a fixed connection, which makes the spacing fixed and the width cannot be adjusted, thus limiting the scope of application. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a core support for engine cylinder head casting, which solves the problems that existing core supports can only support two walls and cannot support multiple support surfaces simultaneously, and that the support block spacing is fixed and has a limited range of applications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a core support for casting an engine cylinder head, comprising a first sliding plate and a second sliding plate arranged at the top and bottom, the first sliding plate and the second sliding plate being semi-circular disc-shaped structures, and a second support block being provided on the left side of the first sliding plate and the right side of the second sliding plate; a second sliding groove being provided on the outer circular surface of both the first sliding plate and the second sliding plate, and a support structure being slidably mounted on the second sliding groove; a first sliding groove being provided at the bottom of the first sliding plate, and an installation groove being provided at the bottom of the first sliding groove; a worm gear being movably mounted in the installation groove; a linkage shaft penetrating the first sliding plate being provided at one end of the worm gear; a slide bar being provided on the side of the second sliding plate that is in contact with the first sliding plate, which slides in cooperation with the first sliding groove; and teeth being provided on the top of the slide bar that cooperate with the worm gear.

[0006] The support assembly includes a slider that slides in conjunction with the first groove. A threaded post is movably mounted on the slider via a first bearing, and a first support block is mounted on the outer end of the threaded post via a threaded sleeve.

[0007] Preferably, the first slide groove is a T-shaped slide groove, and one end of the first slide groove extends through one side of the first sliding plate. This arrangement allows the slide bar to slide into the first slide groove from its end, and to be engaged within the first slide groove.

[0008] Preferably, a limiting strip is movably installed on the edge of the second slide groove by screws. The limiting strip and the second slide groove form a T-shaped slide groove. The slider slides in cooperation with the T-shaped slide groove. This arrangement allows the slider to drive the support assembly to move along the second slide groove, enabling the first support block in the support assembly to face different surfaces and support different surfaces, thus greatly improving the applicability of the device.

[0009] Preferably, a wrench is provided on the outer side of the threaded post. The wrench facilitates the rotation of the threaded post, and through its cooperation with the threaded sleeve, the position of the first support block can be adjusted so that the first support block can fit tightly against different support surfaces.

[0010] Preferably, a knob is provided at the outer end of the linkage shaft. The knob allows for easy rotation of the worm gear via the linkage shaft, which in turn moves the second sliding plate through the teeth, adjusting the distance between the two second support blocks to ensure they are in close contact with the support surface.

[0011] Preferably, both ends of the worm are movably mounted in the mounting groove via a second bearing.

[0012] This utility model provides a core support for casting engine cylinder heads, which has the following advantages:

[0013] 1. This utility model provides a second sliding groove on the first sliding plate and the second sliding block, and a support component is slidably installed through the second sliding groove. Through the cooperation of the first support block, the second support block and the support component, multiple support surfaces can be supported and fixed, making the sand mold of the engine cylinder head more stable.

[0014] 2. This utility model can adjust the distance between the two second support blocks by using the cooperation of worm gear and teeth, and can adjust the position of the first support block by using the cooperation of threaded sleeve and threaded column. Thus, the device can adapt to support engine cylinder head castings with different wall thicknesses, greatly improving the applicability of the device. Attached Figure Description
