The pouring gate of the pouring mold is generally composed of a gate sleeve and a gate plate, wherein the gate sleeve is in a two-half type, the two half gate sleeves are respectively fixed on a female die and a male die, and after the female die and the male die are fixed, the two half gate sleeves are closed to form a storage cavity for storing resin so as to supplement the resin which continuously shrinks in the cavity. The gate plate is integrated and fixed on the gate sleeve, so that the injection amount of resin can be conveniently controlled, and the resin is generally injected into the overflowing gate plate to ensure that the storage cavity is provided with enough resin. Wherein the resin that overflows flows out through the drainage grooves on the gate plate.

In the practical use process of the pouring mold, the pouring gate plate is fixed on the pouring gate sleeve when pouring operation is needed, and the pouring gate plate needs to be detached after the operation is completed, so that the die sinking of the female die and the male die is facilitated. However, during operation, excess resin inevitably overflows the surface of the mold, and this resin easily flows to the fixed connection position of the gate plate and the gate bushing and is difficult to remove after hardening, so that the gate plate is difficult to detach from the gate bushing, and it takes a lot of time. And even if the gate plate is removed, the residual resin on the gate sleeve is difficult to clean, and the tight combination and fixation of the gate plate and the gate sleeve can be influenced when the gate plate is installed next time, so that the resin overflows from the combination part when pouring is carried out again, and vicious circle is formed.
