Cylinder block casting device and method

Abstract

The invention discloses a cylinder block casting device and a method, wherein the device comprises a cylinder block casting mold and a cylinder block casting; the cylinder block casting consists of a pouring gate, a sorue, a cross gate, an ingate and a cavity; and the cylinder block casting is horizontally arranged on the cylinder block casting mold when the cylinder top surface of the cylinder block faces downwards and the machine leg surface of the cylinder block faces upwards. The method comprises the following steps: by using the above cylinder block casting device, the casting liquid is injected into the cylinder block casting device from the pouring gate of the cylinder casting, flows through the sorue, the cross gate and the ingate in sequence and flows in the cavity of the cylinder block casting to complete the casting of the cylinder block. The device and the method in the invention can overcome the defects of poor effects of exhaust and slag dam, low casting yield, easily-damaged bland, uneven wall thickness and the like so as to realize the purposes of good effects of exhaust and slag dam, high casting yield, difficult damaged blank, even wall thickness and high product quality.

Description

technical field [0001] The invention relates to casting technology in the mechanical field, in particular to a cylinder block casting device and method. Background technique [0002] At present, in the process of casting the cylinder block, the casting method of the cylinder block is generally horizontal, that is, as Figure 1a and Figure 1b As shown, the left side of the cylinder block faces up and the right side faces down. [0003] In the process of realizing the present invention, the inventor found that the cylinder block casting process in the above-mentioned prior art has at least the following defects: [0004] (1) The effect of exhaust and slag blocking is poor; [0005] (2) Low yield: the pouring system accounts for a large proportion of the blank weight, and the process yield is low; [0006] (3) The blank is easily damaged: it is easy to crack the weak part of the cylinder block blank when falling sand; [0007] (4) Uneven wall thickness: The wall thickness ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to propose a cylinder block casting device to achieve the effects of exhaust and slag blocking in view of the defects of poor exhaust and slag blocking effects, low yield, easy damage to the blank, and uneven wall thickness in the prior art. Good, the yield is high, the blank is not easy to damage, the wall thickness is uniform, and the product quality is high

[0009] Another object of the present invention is to propose a casting method for a cylinder block to achieve exhaust, slag retaining and The slag effect is good, the yield is high, the blank is not easy to damage, the wall thickness is uniform, and the product quality is high
