Description

Technical Field

[0001] The utility model relates to the technical field of hot runner systems, in particular to an openable and closable manifold plate sealing structure. Background Art

[0002] The manifold is a component used for diverting molten rubber in the hot runner system. In order to prevent leakage from the rubber flow channel during the production process, it is usually necessary to set a sealing structure on the manifold. However, most of the existing sealing structures use a sealing ring directly set on the manifold for sealing. However, this type of sealing structure is prone to wear during the use of the sealing ring, resulting in excessive gaps, which increases the risk of leakage. On the other hand, as the requirements for injection molding products gradually diversify, multi-cavity manifolds are used more widely. The existing sealing structures for multi-cavity manifolds cannot solve the problem of independent control of the flow of rubber in a single cavity. Therefore, based on the above-mentioned problems, it is urgent to propose further solutions. Summary of the invention

[0006] The sealing component includes a gear, a rack connected to the gear transmission, and a driving member for driving the rack to move. One end of the gear extends into the rubber flow channel through the sealing port. The sealing component drives the rack to move through the driving member to drive the gear to rotate in the rubber flow channel to control the opening or closing of the rubber flow channel.

[0007] Furthermore, the gear includes a gear body and a rotating shaft connected to the gear body, and a flow hole is opened at one end of the rotating shaft, and the flow hole is arranged perpendicular to the axial direction of the rotating shaft.

[0008] Furthermore, the output end of the driving member is connected to a rack, and the rack is meshingly connected to the gear body.

[0009] Furthermore, the sealing component also includes a sealing ring, and the sealing ring is arranged in the sealing opening.

[0010] Furthermore, one end of the rotating shaft passes through the sealing ring and is rotatably connected to the diverter plate, and the flow hole is connected to or disconnected from the rubber flow channel during the rotation of the rotating shaft.

[0011] Furthermore, the rotating shaft is provided with a glue passing groove along its axial direction, and the glue passing groove is respectively communicated with the flow hole and the glue flow channel.

[0012] Furthermore, a transfer nozzle is provided at the other end of the rotating shaft, and the transfer nozzle is connected to an external hot runner system.

[0013] Furthermore, the driving member is a pneumatic cylinder or an oil cylinder.

[0014] The beneficial effect of the utility model is that the utility model discloses an openable and closable glue sealing structure of a manifold plate, by setting a glue sealing component on the glue sealing port of the manifold plate, the glue sealing component drives the rack to move through a driving member, and then drives the gear to rotate in the rubber flow channel through the meshing transmission of the rack and the gear, and controls the opening or closing of the rubber flow channel by controlling the rotation angle of the gear.

[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0020] Example 1

[0021] like Figure 1-3 As shown, this embodiment provides an openable and closable manifold plate sealing structure, comprising a manifold 1, the manifold 1 is provided with a glue flow channel and a sealing port 3 connected to the glue flow channel 2, the sealing port 3 is provided with a sealing component for controlling the opening or closing of the glue flow channel 2;

[0022] The sealing component includes a gear 4, a rack 5 connected to the gear 4, and a driving member 6 for driving the rack 5 to move. One end of the gear 4 extends into the rubber flow channel 2 through the sealing port 3. The sealing component drives the rack 5 to move through the driving member 6 to drive the gear 4 to rotate in the rubber flow channel 2 to control the opening or closing of the rubber flow channel 2.

[0023] In this embodiment, a sealing assembly is provided through the sealing port 3 of the manifold 1. The sealing assembly drives the rack 5 to move through the driving member 6, and then drives the gear 4 to rotate in the rubber flow channel 2 through the meshing transmission between the rack 5 and the gear 4. The opening or closing of the rubber flow channel 2 is controlled by controlling the rotation angle of the gear 4. Specifically, when the driving member 6 drives the rack 5 to move and drives the gear 4 to rotate 90° relative to the rack 5, the rubber flow channel 2 is in a closed state; when the driving member 6 drives the rack 5 to move in the opposite direction and drives the gear 4 to reset, the rubber flow channel 2 is in an open state. On the one hand, by applying the above-mentioned sealing structure to the manifold 1 having multiple rubber flow channels 2, it is possible to realize the linkage opening and closing of multiple rubber flow channels 2 at the same time or to realize the separate opening or closing of a single rubber flow channel 2; on the other hand, it is also possible to control the amount of rubber in the rubber flow channel 2 in a timed manner.

[0024] Furthermore, the gear 4 includes a gear body 41 and a rotating shaft 42 connected to the gear body 41, and a flow hole 43 is opened at one end of the rotating shaft 42, and the flow hole 43 is arranged perpendicular to the axial direction of the rotating shaft 42. Specifically, there is an angle between the flow direction of the flow hole 43 and the axial direction of the rotating shaft 42, and the angle is 90°.

[0025] Furthermore, the output end of the driving member 6 is connected to the rack 5, and the rack 5 is meshed with the gear body 41. Specifically, the output end of the driving member 6 is arranged parallel to the diverter plate 1, and the driving member 6 drives the rack 5 to perform linear reciprocating motion along the output end direction thereof, and meshes with the gear body 41 through the rack 5, thereby driving the gear body 41 and the rotating shaft 42 to rotate.

[0026] Furthermore, the sealant assembly further includes a sealant ring 7, which is disposed in the sealant opening 3. Specifically, an internal thread is disposed in the sealant opening 3, and an external thread is disposed on the sealant ring 7 to cooperate with the internal thread. The sealant ring 7 is tightly connected to the sealant opening 3 through threaded connection, thereby preventing the sealant from leaking.

Specifically, when the rotating shaft 42 rotates 90° relative to the rack 5 or the manifold 1, the flow direction of the flow hole 43 is perpendicular to the flow direction of the rubber flow channel 2, and the rubber flow channel 2 is in a closed state; when the rotating shaft 42 is reset, the flow direction of the flow hole 43 is the same as the flow direction of the rubber channel, and the rubber flow channel 2 is in an open state, that is, the rubber in the rubber flow channel 2 can flow out through the flow hole 43 and the rubber groove, thereby being able to control the amount of rubber in the rubber flow channel 2.

[0028] Furthermore, the rotating shaft 42 is provided with a glue passing groove along its axial direction, and the glue passing groove 44 is communicated with the flow hole 43 and the glue flow channel 2 respectively.

The driving member 6 is fixed by an external fixing seat, and the output end of the driving member 6 is connected to the rack 5.
