Benefits of technology

The technical effect of this new design described by this inventor relates to smoother castings produced without any defects caused by excessive gas bubbles or voids inside them due to insufficient lubrication between moving components such as metal plating on dies used in injection molds. This results in better quality castings while also making it easier to fill these cores into their final shape before being completely cured. Additionally, there're several ways to prevent overheating issues when inject molten metals through small gates called internal gaps within the core. Overall, this innovative technology allows for high yields and low manufacture costs associated with current methods like sandwich processes.

Problems solved by technology

This patented describes how current methods for producing thin plate components have limitations due to their high temperature caused by excessive thermal energy from injecting molten material onto them while they hardens quickly at room temperatures. These issues can lead to poor quality productivity and increased scrap rates.

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] A die-casting mold casting method, the flow velocity of the punch in the die-casting process is 0.4 m / s to 0.8 m / s (0.6 m / s in this example, it can also be 0.4 m / s, 0.5 m / s, 0.7 m / s or 0.8.7 m / s, etc.), and the cross-section of the ingate 1 is a polygonal structure, and the rest are the same as those of the prior art.

[0015] Such as figure 1 and figure 2 As shown, the cross section of the ingate 1 includes a first straight side 2, a second straight side 3, a third straight side 4, a fourth straight side 5, a first hypotenuse 6 and a second hypotenuse 7, The first straight side 2 is parallel to the third straight side 4, the second straight side 3 is parallel to the fourth straight side 5, and the distance between the first straight side 2 and the third straight side 4 is equal to the second straight side 3 and the fourth

Abstract

Disclosed is a die-casting mould casting method. The flowing speed of a punch is 0.4 meter per second to 0.8 meter per second in a die-casting process; and the cross section of a flow gate (1) has a polygonal structure. Compared with the prior art, the die-casting mould casting method has the advantages that because the cross section of the flow gate has the polygonal structure, the cooling speed of the center of the flow gate is lower than that of the center of a thick and big portion of a cast, a pressure-maintaining and feeding channel for the cast is formed, the thick and big portion of the cast can be fed in the process of cooling the center of the thick and big portion, shrinkage and loosing can be effectively eliminated, the yield can be greatly improved, and the production cost is reduced. The die-casting mould casting method has the advantages of high yield and low production cost.
