Description

Technical Field

[0001] The utility model relates to the technical field of blank part processing, and particularly relates to a trimming device for die-casting blank parts. Background Art

[0002] With the progress of science and technology and industrial production, die-casting machines are widely used in industries and fields such as automobile manufacturing, transportation, metallurgy, national defense, aviation, and aerospace. Especially for high-performance aluminum alloy die-castings, they are very widely used in all walks of life in the current market. After the die-casting machine forms a product, in order to obtain higher-quality products, at the same time, there will be some unnecessary slag bags, flash, and runners connected to the product. In subsequent processing, it is necessary to remove the slag bags, flash, runners, etc. at the edge parts of the blank parts.

[0003] At present, in the market, for the removal of the gates and slag bags of die-casting blank parts, most of them are completed by punching with a punching press or sawing with a sawing machine. Such removal methods require the cooperation of multiple processes, have a large demand for personnel, and have low production efficiency.

[0004] In addition, for the removal methods using punching presses and sawing machines in the current market, special molds are basically not used. The die-casting blank parts are directly placed in the equipment, and the removal is carried out through manual and single-piece discontinuous operations. This method cannot reasonably determine the position state of the product. The die-casting parts are prone to looseness during the removal process, resulting in easy damage when the die-casting parts come into rigid contact and collision with the equipment. Moreover, the die-casting parts are not positioned stably, which is likely to cause defects such as product deformation, product missing material, and bruising. During the removal process, the removed edges are uneven and have many burrs, and secondary grinding is still required, increasing the product process and affecting the production efficiency. There are many operators involved in the production process, and the equipment safety is difficult to control, presenting a relatively large safety risk. Summary of the Utility Model

[0005] Based on the problem of the low production efficiency of the existing trimming device for die-casting blank parts pointed out in the background art, the purpose of this application is to propose a trimming device for die-casting blank parts. This trimming device for die-casting blank parts reduces the processes such as manual secondary deburring caused by burrs left by punching and other methods, effectively improves the qualified rate of products, reduces the labor demand, saves production costs, and improves the production efficiency.

[0006] The utility model is realized through the following technical solutions:

[0007] This application provides a trimming device for die-casting blank parts, which includes a support plate connected to the base pedestal. A lifting structure is connected to the support plate, a cutting tool is connected to the lifting structure, and a blank positioning mold is installed on the support plate directly below the cutting tool.

[0008] As a preferred embodiment of the present application, the lifting structure includes a hydraulic driving structure connected to the support plate, and the hydraulic driving structure is controlled by a solenoid valve. One end of the hydraulic driving structure is connected to the support plate, and the other end is connected to a top plate, and the cutting tool is connected to the top plate.

[0009] Alternatively, the lifting structure may also be an electric telescopic rod connected to the support plate.

[0010] Alternatively, the lifting structure may also be a cylinder, a hydraulic cylinder or other structures that can achieve telescoping.

[0011] As a preferred embodiment of the present application, a guiding structure is connected between the support plate and the top plate.

[0012] As a preferred embodiment of the present application, the guiding structure includes an upper limit post and a lower limit post connected to the support plate.
