Description

Technical Field

[0001] The utility model belongs to the technical field of gate inserts, in particular to a common gate sub-control structure for injection molds. Background Art

[0002] Many interior products are injection molded using a single mold with two cavities. Due to the complex structure of the product and limitations of cost, product structure, and space, the left and right parts must share a common gate. This shared gate cannot produce either cavity independently, leading to the need for a separate product during production. Utility Model Content

[0003] In response to the above problems, the utility model provides a common gate control structure for an injection mold, including a pressing block, a gate control structure insert, a ball bearing, a ball bearing screw and a rotating block. The rotating block is fixed in the gate control structure insert, the gate control structure insert is locked by a pressing block and a screw, the rotating block is clamped with the ball bearing, the gate control structure insert is pressed on top of the ball bearing through the rotating block, and the ball bearing is locked on the ball bearing screw with a screw. The traditional common gate controls the glue discharge of one side of the gate separately, and the insert needs to be replaced. Each replacement takes at least one hour, which is time-consuming and labor-intensive. The present structure can be directly achieved by rotating with a hexagonal wrench, saving about one hour each time.

[0004] The technical solution of the utility model is as follows: a common gate control structure for an injection mold, comprising: a pressing block, a molding runner, a gate control structure insert, a ball bearing, a ball bearing screw and a rotating block, the rotating block being fixed in the gate control structure insert, the gate control structure insert being locked by a pressing block and a screw, the rotating block being clamped with the ball bearing, the gate control structure insert being pressed above the ball bearing by the rotating block, the ball bearing being locked on the ball bearing screw with a screw, and a molding runner being provided on the pressing block.

[0005] Furthermore, a slot structure is provided on the engaging surface between the rotating block and the ball bearing.

[0006] Furthermore, the slot structures are arranged at intervals of 90°.

[0007] Furthermore, the gate control structure insert consists of three parts: a first insert, a second insert and a third insert. It is an axisymmetric structure with the axis of symmetry being the center line of the second insert. Each insert is provided with multiple screw holes and the inserts are fixed by bolts.

[0008] Furthermore, it also includes a base, and the ball bearing screw is arranged on the base.

[0009] The beneficial effects of the utility model are:

[0010] The traditional shared gate controls the glue discharge from one side of the gate separately, and the insert needs to be replaced. Each replacement takes at least one hour, which is time-consuming and labor-intensive. The structure of this utility model can be directly achieved by turning with a hexagonal wrench, saving about one hour each time. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] It should be noted that in the description of the present invention, the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "clockwise", "counterclockwise", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.

[0017] In this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, "fixed" can refer to a fixed connection, a detachable connection, or an integral connection; connection can refer to a mechanical connection or an electrical connection; connection can refer to a direct connection or an indirect connection through an intermediate medium, and can refer to internal communication between two components or an interaction between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0018] A common gate control structure for an injection mold includes a pressing block 1, a molding runner 2, a gate control structure insert 3, a ball bearing 4, a ball bearing screw 5, a base 6, and a rotating block 7.

[0019] Molding runner: the space through which molten colloid passes.

[0020] Gate runner form: straight gate and hook gate can be used.

[0021] The gate control structure insert 3 consists of three parts: the first insert 301, the second insert 302 and the third insert 303. It is an axisymmetric structure with the axis of symmetry being the center line of the second insert 302. Each insert is provided with multiple screw holes and the inserts are fixed by bolts.

[0022] The rotating block 7 is fixed in the gate control structure insert 3 and locked by the pressing block 1 and screws.

[0023] The rotating block 7 is engaged with the ball bearing 4 , and a groove structure is processed every 90° on the engaging surface of the rotating block 7 .

[0024] The gate control structure insert 3 is pressed on the ball bearing 4 through the rotating block 7.

[0025] The ball bearing 4 is screwed onto the ball bearing screw 5.

[0026] The utility model can realize the functions of simultaneously pouring from both sides of a common gate, pouring from only one side of the two sides, and closing the gate.

[0027] During production, use a hexagonal wrench to rotate the gate control structure and rotate the slot structure to the ball bearing position to achieve simultaneous pouring on both sides of the common gate, pouring on only one side of the two sides, and closing the gate.
