Description

Technical Field

[0001] This utility model relates to the field of sealing strip mold technology, specifically a two-composite sealing strip mold. Background Technology

[0002] Composite rubber sealing strips typically consist of a steel strip (reinforcing skeleton) and rubber (sealing layer), and are widely used in automotive door and window sealing, building curtain wall joint waterproofing, and rail transit vehicle sealing. These sealing strips require good elasticity, weather resistance, and structural strength; therefore, they are usually manufactured using an extrusion molding process, where molten rubber and steel strip are bonded together in a mold, and then cooled and shaped.

[0003] Currently, the common production method involves continuously feeding a steel strip into an extrusion die while simultaneously injecting rubber material through a feed inlet. The rubber material then combines with the steel strip within the die and is extruded to form the final product. This process enables continuous production, improves efficiency, and ensures product consistency.

[0004] However, the extrusion molds for two-component rubber sealing strips in the existing technology usually adopt a fixed flow channel design, which can only achieve rubber composite on one side of the steel strip. It cannot flexibly adjust the composite method according to product requirements. This limitation makes it difficult for the same mold to adapt to the sealing strip production needs of different application scenarios, such as some special working conditions that require rubber to cover both sides of the steel strip at the same time.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-3 As shown, this utility model provides a technical solution:

[0023] A two-component sealing strip mold includes a fixed cylinder 1. A movable ring 2 is movably mounted on the left side of the fixed cylinder 1. An adjustment mechanism is provided at one end of the movable ring 2 inside the fixed cylinder 1. The adjustment mechanism includes a semi-circular material guide shell 6. The semi-circular material guide shell 6 is fixedly connected to the left end of the movable ring 2 inside the fixed cylinder 1. An annular guide groove 7 is formed inside the left side of the fixed cylinder 1 to fit the semi-circular material guide shell 6 with a clearance. The adjustment mechanism also includes a first channel 8 and a second channel 9, which penetrate the middle of the upper and lower ends of the semi-circular material guide shell 6. A channel 8 is provided. A channel 9 is opened in the middle of the semi-circular inner shell 6. A guide mold column 3 is movably installed between the middle of the fixed cylinder 1 and the movable ring 2. A guide mechanism is provided in the middle of the guide mold column 3. The guide mechanism includes a transverse groove 4. The transverse groove 4 is opened through the middle of the guide mold column 3. Rectangular grooves 5 are opened at both ends of the guide mold column 3 and are connected to the middle of the transverse groove 4. An input pipe 10 is connected to the top of the middle of the fixed cylinder 1. A circular hole 11 matching the guide mold column 3 is opened through the middle of the movable ring 2.

[0024] In this embodiment, the coordinated operation of the movable ring 2 and the semi-circular inner guide shell 6 enables rapid switching between single-sided and double-sided composite working modes. Specifically, when double-sided composite is required, the movable ring 2 is simply adjusted to the first working position, connecting the input pipe 10 to the upper channel 8, while the lower channel 8 remains open, allowing simultaneous composite on both sides of the steel strip. When single-sided composite is required, the movable ring 2 is adjusted to the second working position, connecting the input pipe 10 to the second channel 9, enabling single-sided composite of the steel strip. This technical solution effectively overcomes the technical shortcomings of traditional fixed flow channel molds, which cannot adapt to different composite requirements, allowing the same mold to meet various working conditions.

[0025] Working principle: The steel strip enters the mold from the left side of the fixed cylinder 1, while molten rubber material is injected into the middle top of the fixed cylinder 1 through the input pipe 10; the axial adjustment movable ring 2 drives the semi-circular guide inner shell 6 to slide in the annular guide groove 7. The pointer on the movable ring 2 cooperates with the scale on the fixed cylinder 1 to accurately position and adjust the angle; when double-sided lamination is required, the movable ring 2 is adjusted to the specified angle, so that the input pipe 10 is connected to the channel 8 at the upper end of the semi-circular guide inner shell 6. Due to the semi-circular structure of the semi-circular guide inner shell 6... Due to its structural characteristics, the lower channel 8 is naturally kept open, allowing the molten material to flow to both sides of the steel strip simultaneously through both upper and lower channels 8. When single-sided lamination is required, the movable ring 2 is adjusted to another specified angle, connecting the input pipe 10 with channel 9, allowing the molten material to flow to the upper end of the steel strip through channel 9. The molten material enters the rectangular groove 5 of the guide mold column 3, while the transverse groove 4 of the guide mold column 3 is used for guiding the steel strip. After the molten material completes flow channel integration in the rectangular groove 5, it is precisely lamination with the continuously conveyed steel strip in the middle of the guide mold column 3.

[0026] It should be noted that the outer periphery of the movable ring 2 is provided with a worm gear and a worm. The worm gear and the worm form a transmission pair to drive the movable ring 2 to adjust its angle. In this way, the movable ring 2 can achieve self-locking after adjusting its angle. In addition, the guide mold column 3 is rigidly connected to the external support structure by welding.
