High-intensity water channel core of crankcase body and high-intensity water channel core fixed mould of crankcase body

Abstract

The invention discloses a high-intensity water channel core of a crankcase body, which comprises a plurality of hollow column-shaped units connected side by side in the vertical direction, a strengthening support plate parallel to the vertical direction is arranged between every two adjacent hollow column-shaped units, and the left side and the right side of each strengthening support plate are placed in a connecting body between the two adjacent hollow column-shaped units. The invention further discloses a high-intensity water channel core fixed mould of the crankcase body, which comprises a plurality of fixed mould cylinder cups connected side by side in the vertical direction, and a supporting tank is arranged between every two fixed mould cylinder cups, used for mounting the strengthening support plate, and parallel to the vertical direction. According to the invention, through additionally arranging the strengthening support plate between every two adjacent hollow column-shaped units, the water channel core is enabled to be deformed or broken unlikely, the service life is prolonged, sand grains are prevented from being produced inside the water channel cavity of the crankcase body, and the qualified size of the water channel of the crankcase body is ensured.

Description

technical field [0001] The invention relates to a waterway core of a crankcase body and a fixed mold for manufacturing the waterway core, in particular to a high-strength waterway core of a crankcase body and a fixed mold for a high-strength waterway core whose strength is improved by adding a reinforcing support plate. Background technique [0002] In the casting production process of automobile engines, the casting model of the crankcase usually includes a main core, a water channel core, an oil channel core, an outer core and an end face core. At present, among the engine crankcase castings produced by the company, the shape of the water channel of the crankcase is an annular gap-shaped thin cavity. Therefore, when designing the casting sand core of the crankcase, the water channel core forming the water channel is also annular. Thin-walled sand cores. This kind of thin-walled waterway core structure is prone to deformation or fracture during core making, parking, transp...

AI Technical Summary

Problems solved by technology

This kind of thin-walled waterway core structure is prone to deformation or fracture during core making, parking, transportation, molding and pouring, and the casting is therefore scrapped or it is difficult to clean the sand in the inner cavity, which not only reduces the qualified rate of the casting, but also increased cost

In order to prevent the deformation or fracture of the waterway core, it is necessary to use a core support (a metal support used to support the core in the mold) to fix the waterway core, but the conventional core support structure cannot be applied to the waterway core.
