Applying force to the holding portion 51 can make one end of the runner plug 5 enter the inside of the first runner 41 or the second runner 42 so that the liquid raw material cannot flow through, or can make one end of the runner plug 5 withdraw from the first runner 41 or the second runner 42 so that the liquid raw material can flow through; the runner plug 5 and the connection hole 13 can be movably connected by means of interference connection, snap connection, threaded connection, etc., and the operation is simple.

[0039] Further, the runner plug 5 includes a support column 52, a clamping member 53, and a shut-off plug 55; the shut-off plug 55 is arranged at one end of the support column 52 to enter the runner to intercept the liquid stock solution; one end of the clamping member 53 is connected to the lower part of the support column 52, and the other end of the clamping member 53 is provided with a handle 531, and the handle 531 protrudes from the outer side of the moving mold 1 to form a part of the holding portion 51; a clamping protrusion 532 is provided on the outer side wall of the clamping member 53, and a clamping groove 131 is provided on the inner side wall of the connection hole 13, and the clamping protrusion 532 is adaptively clamped with the clamping groove 131, so that the runner plug 5 is not easily detached from the connection hole 13; an activity gap 54 is provided between the inner side wall of the clamping member 53 and the support column 52. Applying force to the handle 531 can make the clamping member 53 approach the support column 52 to release the clamping of the clamping protrusion 532 and the clamping groove 131, so as to facilitate the sliding of the runner plug 5 in the connection hole 13 and then make the shut-off plug 55 enter or exit the runner; releasing the force applied to the handle 531 can make the clamping member 53 elastically open away from the support column 52 to facilitate the clamping of the clamping protrusion 532 and the clamping groove 131.

[0040] Further, a positioning groove 552 is recessed at the bottom of the injection channel 4 of the moving mold 1. The position of the positioning groove 552 corresponds to the connection hole 13. After one end of the shut-off plug 55 enters the runner, it can be adaptively inserted into the positioning groove 552 to improve the connection stability of the shut-off plug 55 in the runner, and the shut-off plug 55 is not easily shaken under the drive of the liquid raw material.

When the clamping protrusion 532 is clamped with the second clamping groove 131b, the bottom end of the shut-off plug 55 exits the injection channel 4, so that the liquid raw material can flow through the injection channel 4. The second clamping groove 131b is also used to limit the shut-off plug 55 so that it is not easily separated from the connection hole 13.

[0042] Further, there are two clamping members 53; the two clamping members 53 are symmetrically arranged on the support column 52. During use, by applying force to the handles 531 of the two clamping members 53 simultaneously, the two clamping members 53 can be made to approach each other to release the clamping between the clamping protrusion 532 and the clamping groove 131. The operation is convenient, and the two clamps make both sides of the runner plug 5 be clamped with the connection hole 13 at the same time, making the connection between the runner plug 5 and the clamping hole 132 more stable.
