Description

technical field [0001] The invention relates to the technical field of die-casting, in particular to a digital full-automatic die-casting equipment. Background technique [0002] Die casting is a precision casting method that uses high pressure to force molten metal into a complex-shaped metal mold. A die-casting machine is a machine used for die-casting. Under pressure, the die-casting machine hydraulically injects molten metal into a mold for cooling and forming. After the mold is opened, a solid metal casting can be obtained. [0003] The traditional die casting machine has the following disadvantages: [0004] (1) In the clamping device, only the hydraulic cylinder is used to clamp the mold, and there are only two single actions of forward and backward. The hydraulic cylinder cannot accurately locate the clamping position, resulting in inaccurate clamping position, poor clamping effect, and affecting Stable performance of injection action with strong injection pressure...

AI Technical Summary

Problems solved by technology

[0004] (1) In the clamping device, only the hydraulic cylinder is used to clamp the mold, and there are only two single actions of forward and backward. The hydraulic cylinder cannot accurately locate the clamping position, resulting in inaccurate clamping position, poor clamping effect, and affecting Stable execution of injection action with strong injection pressure

[0005] (2) In the injection device, the push-down mechanism and the injection plunger of the injection mechanism are rigidly connected, not only the mechanical structure is easily damaged, but also when the injection is made, it is not known when the mold cavity can Filling, that is, it is impossible to know the time point when the mold cavity is filled; at the same time, there is no guarantee that the stroke of the press can fill the mold cavity

As a result, the degree of completion of the shot is reduced

[0006] (3) In the material chamber of the injection device, the piston that controls the feeding is a simple piston structure that only includes a slope, and moves up and down entirely by air pressure without a guiding structure, which causes the piston to easily shift left and right during the up and down movement , unstable phenomenon; at the same time, only rely on the slope to seal the feed port, low stability

[0007] (4) When the injection device is installed, the position is checked manually; and every time the injection device needs to be replaced, the injection device needs to be re-installed and positioned manually, which is time-consuming and laborious, and the installation and positioning are not accurate

[0008] (5) The method of manually feeding materials into the furnace is adopted. Due to the influence of human factors, it is impossible to control the feeding materials. Adding too many raw materials will cause the temperature in the furnace to drop sharply, thereby affecting the stability of the temperature in the furnace. The requirements are very high, and the temperature drop will inevitably affect the quality of the final casting product.
