Description

Technical Field

[0001] This utility model relates to the field of centrifugal mold technology, and more specifically, to an improved centrifugal casting mold for high-speed steel roller press sleeves. Background Technology

[0002] A centrifugal casting mold for roller sleeves is a specialized mold used to produce roller sleeves. It is manufactured using a centrifugal casting process, a unique casting method in which molten metal is poured into a high-speed rotating mold. Due to the mold's rotation, the metal fills the mold cavity under centrifugal force, forming the desired shape. This method can produce high-quality castings with a dense structure, free of porosity and inclusions.

[0003] In existing centrifugal casting molds for roller sleeves, only one roller sleeve can be cast at a time, which is extremely inefficient and not stable enough during rotation. Therefore, in order to solve the above problems, the existence of an improved centrifugal casting mold for roller sleeves of high-speed steel roller press is crucial. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide an improved centrifugal casting mold for high-speed steel roller press sleeves, which can solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, according to one aspect of this utility model, more specifically, an improved centrifugal casting mold for a high-speed steel roller press, a base is provided. Two drive rollers are rotatably mounted on the top of the base. A support platform is fixedly mounted on one side of the base. A liquid discharge pipe is fixedly mounted on the top of the support platform. Three mold bodies are driven by the tops of the two drive rollers. A first liquid discharge port, a second liquid discharge port, and a third liquid discharge port are respectively opened inside the three mold bodies on the outside of the liquid discharge pipe. A switch for controlling the first, second, and third liquid discharge ports is slidably mounted on the outside of the liquid discharge pipe. The multiple mold bodies are engaged and connected. A connecting sleeve is fixedly mounted on one side of each of the multiple mold bodies. A support rod is fixedly mounted on one side of the base. A clamping mechanism is rotatably mounted on the top of the support rod.

[0006] Furthermore, each of the three connecting sleeves is threaded with four first bolts on its outer side and tightly fitted onto the outer side of the mold body on one side, with the bottom of each first bolt threaded to the mold body.

[0007] Furthermore, the clamping mechanism includes a rotating rod rotatably mounted on the top of the support rod, a mounting block rotatably mounted on the top of the rotating rod, a telescopic cylinder fixedly mounted on one side of the mounting block, a fixing block telescopically mounted on the bottom of the telescopic cylinder, and clamping rollers rotatably mounted on both sides of the bottom of the fixing block, with both clamping rollers tightly fitted to the top sides of the mold body.

[0008] Furthermore, the outer side is provided with a first liquid outlet and a second liquid outlet in sequence below the first liquid outlet, the second liquid outlet and the third liquid outlet, and on one side. A sealing sleeve is fixedly provided on one side of the sealing sleeve, and the sealing sleeve is slidably disposed inside the support platform.

[0009] Furthermore, each of the three mold bodies has a retaining ring fixedly installed inside on the side near the connecting sleeve, and each of the three mold bodies has a snap-fit ​​block fixedly installed on the side away from the connecting sleeve, and the snap-fit ​​blocks are snapped into one side of the retaining ring.

[0010] Furthermore, a sealing ring is fixedly connected to one side of the three mold bodies away from the liquid outlet, a sealing block is fixedly provided on one side of the sealing ring, and a second bolt is threadedly connected to the outer side of the sealing ring.

[0011] Furthermore, a funnel is fixedly installed at the top of the liquid inlet tube.

[0012] The beneficial effects of this improved centrifugal casting mold for high-speed steel roller press sleeves are as follows:

[0013] By setting up a mold body, a connecting sleeve, and a liquid pouring pipe, the three mold bodies are spliced ​​together by the connecting sleeve during use, and the solution is injected evenly through the liquid pouring pipe, thereby realizing simultaneous casting of the three roller sleeves, which effectively improves the casting efficiency. At the same time, by setting up a clamping mechanism, the casting process is more stable, which effectively improves the practicality.

[0014] The first bolt facilitates assembly and disassembly; the switch for controlling a single outlet during pouring ensures uniform pouring from the three mold bodies; the baffle ring and snap-fit ​​block improve the tightness of the assembly structure; the sealing ring further enhances the tightness of the structure; and the funnel facilitates the pouring of the solution.
