Aluminum alloy engine cylinder block casting waste removal device and removal method

Abstract

The invention relates to the field of automobile engine manufacturing, and discloses an aluminum alloy engine cylinder block casting waste removal device, which includes a fuselage frame, and the fuselage frame includes a horizontal quadrilateral fuselage frame and four four corners respectively located below the fuselage frame. Supporting feet, a movable waste collection vehicle is provided under the fuselage frame, a conical hopper is provided above the fuselage frame, the outlet at the bottom of the hopper matches the fuselage frame, and a slag impact plate and material are provided on the fuselage frame. The handle impact pile, the slag bag impact plate and the material handle impact pile are located in the hopper and are respectively located at the two ends of the hopper, and the slag bag impact plate and the material handle impact pile are all lower than the upper surface of the hopper. The invention also discloses a removal method of the aluminum alloy engine block casting waste removal device. The aluminum alloy engine cylinder body casting waste removal device and the removal method thereof of the present invention cancel the trimming mold and the hydraulic system, have low failure rate, high quality, and are convenient for model switching and management.

Description

technical field [0001] The invention relates to the field of automobile engine manufacturing, in particular to an aluminum alloy engine cylinder body casting waste removal device and a removal method thereof. Background technique [0002] Aluminum alloy engine block casting is generally high-pressure injection casting. In order to quickly fill the cavity of the mold with aluminum liquid and avoid defects such as air bubbles and lack of meat during the filling process, the casting molds are designed with aluminum hydraulic injection ports and filling flow paths. After the cylinder body is cast and cooled and finalized, these aluminum materials in the inlet path are solidified into material handles (also known as pouring risers, which belong to waste). [0003] In addition, there is a certain error in the weight (volume) of the aluminum liquid poured into the mold each time. In order not to reflect this error on the cylinder, an extra cavity is designed at the end of the mold ...

AI Technical Summary

Problems solved by technology

[0007] 1. More equipment, more cost, more management: auxiliary equipment such as trimming machines (edge ​​punching machines) require hydraulic systems, hydraulic stations, molds that require trimming, etc., and the cost of equipment is high;

[0008] 2. Large area: There are many auxiliary equipment around the die-casting machine, such as cylinder liner conveying device, release agent spray device, pick-up robot, insert robot, workpiece cooling device, workpiece off-line device, etc., around the die-casting machine The layout area is very crowded, and the edge trimming machine (edge ​​punching machine) and its hydraulic station, hydraulic system, etc. need to occupy an area of ​​up to 3 square meters here;

[0009] 3. It is inconvenient to switch models: there are 3-cylinder and 4-cylinder engine blocks with various displacements, as well as naturally aspirated or turbocharged engine blocks, so there are many trimming molds, which need to be replaced Trimming mold is troublesome;

[0010] 4. Inconvenient mold management: There are many molds in the trimming machine, which need to be stored and managed, which not only requires an occupied area, but also increases management items;

[0011] 5. The workshop environment is poor: due to the residual hydraulic oil on the ground of the hydraulic station of the trimming machine (edge ​​punching machine), frequent maintenance and cleaning are required, and the environment is relatively poor;

[0012] 6. High failure rate: In addition to minor failures such as the hydraulic system of the trimming machine, various motion sensors, and PLC operating programs, the most frequent failures are: cut off (washed off) handles and slag bags often remain on the mold, As a result, it is difficult to put the next piece of cylinder into the mold, resulting in more small shutdowns of the production line. For this reason, some manufacturers have designed cleaning devices: some are designed for mechanical cleaning, and some are designed for blowing cleaning. Although these cleaning methods can reduce the number of shutdowns , but added equipment maintenance items
