The appropriateness of the gate selection is directly related to whether the injection molded product can be injected intact and with high quality. The gate position plays a decisive role in the shape of the melt flow front and the effect of the holding pressure. Therefore, it also determines the strength and other properties of the injection molded product.

[0003] For example, a die-casting mold structure with a central feed gate disclosed in the authorization announcement number CN208214279U includes a fixed mold core block, a movable mold core block, and a mold cavity arranged between the fixed mold core block and the movable mold core block, a die-casting central movable block is arranged between the fixed mold core block and the movable mold core block, a gate sleeve is arranged on the outer circumference of the central movable block, and the inner gate directly connects the material cake and the die-casting cavity;
