Description

Technical Field

[0001] The utility model belongs to the field of nylon casting, in particular to a casting mold for a nylon guide slide block. Background Art

[0002] Nylon is used as a vibration-damping and wear-resistant material to replace nonferrous metals and alloy steel in machinery, and has irreplaceable value in transmission wear fields where lubricants are not suitable (such as medical, health, and food industries). Nylon sliders are a common high-load, high-wear-resistant mechanical part among nylon products, and the market demand is huge.

[0003] At present, the Chinese utility model with the announcement number: CN 212860139U discloses that the utility model discloses a mold for centrifugally casting a nylon slider, including a disc-shaped upper mold and a lower mold that is also disc-shaped and connected to a centrifuge through a flange, wherein there is a casting port perpendicular to the disk surface in the middle of the upper mold, and four or more cavities are evenly distributed in a circular array in the upper mold, and the casting port and each cavity are connected by a disc-shaped groove. The outer ring of the lower mold is provided with a guide block for easy installation, and the mold surface is a disc-shaped groove. During casting, the lower mold is connected to the centrifuge, and the upper mold is installed on the lower mold. Turn on the centrifuge, pour liquid nylon into the casting port, and under the action of centrifugal force, the liquid nylon flows into each cavity evenly and simultaneously through the disc-shaped groove, and finally fills the cavity and is formed at the same time. After solidification, separate the upper and lower molds and take out the formed nylon slider. Using this mold, several times the number of nylon sliders can be cast in one casting, which greatly improves work efficiency, reduces product defects and improves the yield rate.

[0004] During the production of the mold for the cast nylon slider, the upper mold and the lower mold are fixed by bolts. This fixation is not only cumbersome, but also requires simultaneous tightening of multiple bolts, which increases the actual tightening time and reduces the production efficiency of the nylon slider. At the same time, during demolding, the cast nylon slider will adhere to the mold due to the temperature, which will make demolding inconvenient. Utility Model Content
