For runner wax parts of different fan-shaped specifications, the existing technology, when mass-producing on the runner mold, the different specifications of the cavities accommodating the different specifications of the runner wax parts are connected to each other, resulting in unstable pressure changes when the wax liquid fills the mold and flows into the different specifications of the cavities, affecting the quality of the runner wax parts in the mold. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a runner mold that can press different fan-shaped specifications.

[0004] The present invention is achieved through the following technical solutions.

[0006] There are runner molds with cavities A and movable plates B of different specifications.

[0007] include:

[0008] A movable block plate A having a cavity A, wherein the cavity A is a plurality of cavities connected to each other;

[0009] A movable plate B having a cavity B, wherein the movable plate B is a plurality of plates connected to each other;

[0010] The mold cavity A and the injection mold cavity B are both fan-shaped, and the mold cavity A and the injection mold cavity B have different specifications.

[0011] Lifting pins A are fixed at both ends of the movable block plate A; and lifting pins B are fixed at both ends of the movable block plate B.

[0012] The movable block plate A is provided with a wax injection channel A; the movable block plate B is provided with a wax injection channel B; a common movable block is installed between the movable block plates A and B, so that the wax injection channel A and the wax injection channel B are separated.

[0013] It also includes a mounting seat, on which the movable block plate A, movable block plate B and universal movable block are placed, and the sides of the movable block plate A and movable block plate B are limited by the mounting seat.

[0014] A handle is fixed on the side of the mounting seat.

[0015] The beneficial effect of the present invention is that the wax liquid is injected into multiple cavities A and multiple cavities B respectively through wax injection channels A and B, so that the wax liquid can flow independently to the cavity A area and the cavity B area, thereby solving the problem of unstable pressure changes when the wax liquid fills the mold and flows into cavities of different specifications, thereby avoiding affecting the quality of the runner wax parts formed in the mold.

[0018] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0019] like Figure 1 shown.

[0020] The present application discloses a runner mold capable of pressing different fan-shaped specifications, including:

[0021] The movable block plate A1 has a cavity A11, and the cavity A11 is multiple and connected to each other; a wax injection channel A13 is provided on the movable block plate A1 in the middle of the cavity A11.

[0022] The movable block plate B2 has a mold cavity B21, and the mold cavities B21 are multiple and connected to each other; the movable block plate B2 in the middle of the mold cavity B21 is provided with a wax injection channel B23; the mold cavity A11 and the injection cavity B21 are both fan-shaped, and the mold cavity A11 and the injection cavity B21 have different specifications. A universal movable block 3 is installed between the movable block plate A1 and the movable block plate B2, so that the wax injection channel A13 and the wax injection channel B23 are separated.

[0023] The wax liquid is injected into multiple cavities A11 and multiple cavities B21 respectively through wax injection channels A13 and B23, so that the wax liquid can flow independently to the cavity A11 area and the cavity B21 area, thereby solving the problem of unstable pressure changes when the wax liquid fills the mold and flows into cavities of different specifications, thereby avoiding affecting the molding quality of the runner wax parts in the mold.
