Problems solved by technology

[0002] Engine cylinder liners are generally manufactured by centrifugal casting process. Existing centrifugal casting equipment needs to rely on a lot of manual operations, such as mold clamping, pouring, mold opening, demoulding and other processes. Manual operations are required, which is labor-intensive and low in production efficiency; , the centrifugal casting equipment in the prior art generally has a fixed runner, that is, the casting liquid flows into the mold from a fixed position, which makes the distribution of the casting liquid in the mold uneven, prolongs the molding cycle, and the cylinder liner is prone to local internal stress, which affects Forming quality of cylinder liner

Embodiment 1

[0026] Such as Figure 1-4 As shown, a cylinder liner centrifugal casting system includes a casting unit and a centrifugal unit. The centrifugal unit includes a cylindrical mold body 10 rotatably arranged along a horizontal axis. The first end of the cylindrical mold body 10 is provided with a first end plate 11. The second end of the cylindrical mold body 10 is provided with a second end plate 12, and the center of the second end plate 12 is provided with a casting channel, and the casting unit is located outside the casting channel, and the casting unit is used for casting The liquid is introduced into the interior of the cylindrical mold body 10, and the casting unit is movable along the axial direction of the cylindrical mold body 10; The inside of the mold body 10 is ejected, and a cylinder liner exporting device 50 is provided below the outer side of the casting channel. The cylinder liner exporting device 50 is used to guide and collect the ejected cylinder liners 1 . ...

Embodiment 2

[0037] Based on the above-mentioned embodiment 1, this embodiment proposes a centrifugal casting process for a cylinder liner 1, which includes the following steps:

[0038] Step 1: Casting liquid smelting, adding raw materials to an intermediate frequency electric furnace for melting and slag removal to obtain casting liquid;

[0039] Step 2: Prepare the centrifugal casting machine, clean the inner wall of the centrifugal casting machine, spray the coating, and preheat the mold;

[0040] Step 3: Move the sprue to the sprue of the centrifugal casting machine;

[0041] Step 4: Casting, start the centrifugal casting machine, use the ladle to pour the pouring liquid into the sprue, and the pouring liquid flows into the mold through the sprue;

[0042] Step 5: Demoulding, after the casting is cooled, take the casting out of the mold, and the cylinder liner 1 is casted;

[0043] In described step 5, the concrete method of demoulding is:

[0044] 1) The driving claw 14 of the dri...

Abstract

The invention belongs to the technical field of automobile part casting machining, and particularly relates to a cylinder sleeve centrifugal casting machine. The cylinder sleeve centrifugal casting machine comprises a casting unit and a centrifugal unit, wherein the centrifugal unit comprises a cylindrical mold body rotationally arranged along the horizontal axis; the casting unit is used for guiding casting liquid into the cylindrical mold body and is movably arranged in the axial direction of the cylindrical mold body; the centrifugal unit comprises a demolding device; the demolding device is used for ejecting a formed cylinder sleeve out of the cylindrical mold body; and a cylinder sleeve guiding-out device is further arranged below the outer side of a casting channel and used for guiding, conveying and collecting the ejected cylinder sleeve. According to the cylinder sleeve centrifugal casting system, a first end plate and a second end plate are arranged to be of a movable structure, after the cylinder sleeve is formed, the first end plate is used for ejecting the cylinder sleeve out of a mold, automatic demolding of a casting is achieved, and the cylinder sleeve casting machining efficiency is improved.
