Problems solved by technology

[0003] However, the above-mentioned control method of the die-casting six-axis manipulator still has obvious defects in the process of use: 1. The above-mentioned device realizes the clamping of the die-casting molded parts through the mechanical arm Because the die-casting molded parts usually have a special-shaped structure, it is difficult for the manipulator to pick up the parts, and it is affected by the change of the mold. The gripping manipulator needs to adjust the gripping point according to the influence of the change of the mold, thus increasing the Debugging burden, and because the raw material of die-casting is usually an alloy material without iron, its hardness is relatively low, so it is easy to cause damage to the molded part due to excessive clamping force during the clamping and picking process, thereby affecting the quality of the molded part ; 2. The function of the above-mentioned device is relatively single, and it can only clamp and take out the die-casting molded parts. In the die-casting process, the surface of the mold spraying place is always under a high temperature gradient, and the thermal shock on the surface is very large. Therefore, a large temperature gradient is one of the reasons for damaging the life of the mold and reducing the performance of the casting product. Therefore, in the clamping gap of the formed part, the fixed mold and the movable mold are usually sprayed to cool down the temperature, while the existing technology Spraying cooling and clamping and picking are usually realized by different robotic arms, and the two work alternately to prolong the time of picking and spraying, and because of the use of different robotic arms, the mechanical cost is increased

Embodiment 1

[0028] A manipulator for die-casting processing, including a fixed mold 1, a movable mold 2 and a multi-purpose manipulator 3, the fixed mold 1 and the movable mold 2 cooperate to form a forming cavity for die-casting, and the upper and lower sides of the fixed mold 1 are movably inserted with The blanking push rods 4 respectively connected to different telescopic cylinders, and the multipurpose manipulator 3 are movably connected to the working end of the manipulator 5;

[0029] The multi-purpose manipulator 3 includes a housing 6. The multi-purpose manipulator 3 is located on the housing 6 on one side of the movable mold 2 and is provided with a number of fixed cooling nozzles 7 in a rectangular array. The liquid supply chamber 8 is connected, and the multi-purpose manipulator 3 is away from the fixed cooling nozzle 7. On the shell 6, there are a number of telescopic clamping thimbles 9 and spraying telescopic thimbles 10 inserted in an array, and several spraying telescopic ...

Embodiment 2

[0033]In this embodiment, the outside of the telescopic clamping thimble 9 and the spraying telescopic thimble 10 are wrapped with a rubber layer. By setting the wrapping rubber layer, the gap between the telescopic clamping thimble 9 and the spraying telescopic thimble 10 and the shell forming hole is The frictional force increases, so as to ensure that the telescopic clamping thimble 9 and the spraying telescopic thimble 10 can maintain this state when they are in the squeezed state, and at the same time, because the spraying telescopic thimble 10 and the second liquid supply chamber 13 are movably matched, the rubber layer The setting can further ensure the airtightness between the matching holes, and prevent a large amount of liquid from overflowing around the spray retractable thimble 10 in the spray state.

Embodiment 3

[0035] In this embodiment, slide bar holes are provided on both sides of the reset push plate 14, and a translation slide bar 21 is inserted in the slide bar holes, and both ends of the translation slide bar 21 are fixedly connected to the inner wall of the housing 6. The cooperation between the rod hole and the translation sliding rod 21 ensures the stability of the reset pushing plate 14 during the stretching process.

[0036] A robot for die-casting processing includes a mechanical fixture for non-destructive blanking of a die-casting body, and the mechanical fixture adopts the above-mentioned manipulator for die-casting processing.

[0037] Work steps:

[0038] Step 1: Forming a molding cavity for die-casting by cooperating with the fixed mold 1 and the movable mold 2, and using a die-casting device to die-cast the molten metal solution inside the cavity to form a molding;

[0039] Step 2: Control the movable mold 2 to separate from the fixed mold 1 through the hydraulic ...

Abstract

The invention provides a manipulator and a robot for die-casting machining. The manipulator comprises a fixed mold, a movable mold and a multi-purpose manipulator, the fixed mold and the movable mold are matched to form a forming cavity for die casting, and spraying holes in the top ends of spraying telescopic ejector pins communicate with liquid inlet holes formed in the side edges of the spraying telescopic ejector pins; and the reset pushing plate movably abuts against the ends, close to the fixed cooling spray head, of the telescopic clamping ejector pin and the spraying telescopic ejector pin, and the air supply cabin communicates with an air supply valve arranged on the side wall of the shell. According to the invention, material bearing is realized in an ejector pin telescoping manner; the fence type telescopic clamping ejector pin and the spraying telescopic ejector pin are adopted at the edge contour of a forming material for limiting, then the forming material is prevented from displacing, the limiting mode is not affected by the shape of a forming part, adaptation can still be performed after a mold is changed for multiple times, and the forming material enters a spraying cooling state immediately after being taken down; and spraying of the shielding area is intelligently stopped so that the working efficiency is improved.
