Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0023] see Figure 1~2 , Figure 1~2 It is a schematic diagram of the structure of heat dissipation ribs of a die-casting mold, wherein, 10 is a mold, 20 is a mold rib, there are several mold ribs 20, and there are small gaps 30 between two mold ribs 20, and these small gaps 30 are often Difficult to polish in place.

[0024] The polishing method for the heat dissipation ribs of the above-mentioned die-casting mold includes the following steps:

[0025] (1) Coarse throwing:

[0026] Use the sandpaper disc 11 to polish the two sides of the small gap 30. The two sides are flat and have a large area, and the sandpaper disc 11 is used to polish the efficiency; the roughness of the sandpaper disc 11 is #150, and it is composed of three layers of sandpaper bonded in sequence , the sandpaper disc 11 is fixed o...

Abstract

The invention relates to the technical field of mould polishing and specifically relates to a polishing method for a radiation rib of a die-casting mould. The polishing method comprises the following steps: (1) rough polishing: adopting an abrasive paper plate for polishing a plane and adopting abrasive paper grains or fiber oilstone for polishing a non-planar part till clearing away all the spark marks; (2) semi-fine polishing: coating lubricant on a to-be-polished position, adopting the abrasive paper plate for polishing the plane and adopting the abrasive paper grains or fiber oilstone for polishing the non-planar part till uniform gloss appears on a metallic surface; (3) fine polishing: adopting the abrasive paper plate for polishing the plane and adopting the abrasive paper grains or fiber oilstone for polishing the non-planar part till the mould can reflect light when light irradiates on the mould. According to the polishing method provided by the invention, the problems of small clearance and difficulty in small-hole polishing of the radiation rib of the die-casting mould are effectively solved, the problems of damage to products, mould sticking, and the like, during a die-casting process, are solved, and the continuous and stable proceeding of the die-casting process is ensured.

Description

technical field [0001] The invention relates to the technical field of mold polishing, in particular to a polishing method for heat dissipation ribs of a die-casting mold. Background technique [0002] Die-casting molds usually need to be polished after finishing milling, EDM, grinding and other processes. At present, the polishing of die-casting molds is mainly done by hand, using sandpaper, oil stone and other tools to polish slowly. However, the heat dissipation ribs of the mold are generally thin and deep, and these parts are often difficult to polish in place, resulting in problems such as mucous membranes and broken thimbles in die-casting production, reducing the service life of the mold, increasing costs, and causing bad quality of die-casting products. influences. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a polishing method for die-casting mold cooling ribs, which effectively solves...
