Description

Technical Field

[0001] This utility model relates to the field of hollow casting technology, specifically to a double-layer reinforced hollow casting structure. Background Technology

[0002] Investment casting produces castings containing hollow channels by using ceramic or metal cores inside and removing these cores after pouring, thus creating hollow, slender channels inside the casting. This is especially useful for castings with curved, slender channels.

[0003] In the existing technology, tubular hollow castings have limited functionality, the hollow structure affects the overall strength of the casting, and the high temperature during use can cause burns to workers who come into contact with the casting, resulting in insufficient safety.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A double-layer reinforced hollow casting structure includes an outer tube and an inner tube. The outer tube is sleeved and fixed to the outside of the inner tube. Connecting rings are fixedly connected to the upper and lower ends of the inner tube. The connecting rings are sleeved and fixed to the outer walls of the upper and lower ends of the inner tube. The top of the connecting ring is provided with a circumferential through hole at equal intervals.

[0008] Preferably, the outer tube has symmetrical through holes on one side of its outer wall, and each of the through holes is fixedly connected to a connecting pipe. The inner cavity of the outer tube has circumferentially spaced reinforcing ribs.

[0009] Preferably, each of the reinforcing ribs is equidistantly connected with reinforcing plates on its outer side, and the reinforcing ribs are fixedly connected to the inner wall of the outer tube through the reinforcing plates, and the reinforcing ribs are fixedly connected to the outer wall of the inner tube.

[0010] Preferably, the inner tube has circumferentially spaced connecting grooves on its inner wall, and a first reinforcing plate is fixedly connected inside each connecting groove, while a second reinforcing plate is fixedly connected to the outside of the first reinforcing plate.

[0011] Preferably, the top side of the first reinforcing plate is flush with the inner wall of the inner tube, and the inner side of the second reinforcing plate is fixedly connected to the inner wall of the inner tube.

[0012] Preferably, buffer arc-shaped plates are equidistantly connected between the second reinforcing plates, and the outer side of the buffer arc-shaped plates is flush with the outer side of the second reinforcing plates.

[0013] The beneficial effects of this utility model are as follows: it allows the cooling medium to flow between the equally spaced reinforcing ribs, which increases the strength of the outer wall of the outer tube and reduces its temperature, preventing burns to workers when using the casting. It also improves the strength of the inner wall of the inner tube, effectively preventing dents caused by prolonged impact from water flow. Furthermore, it enhances the strength of the second reinforcing plate and provides a buffering effect for the internal liquid flow, further improving the overall functionality of the hollow casting.
