Description

Technical Field

[0001] This utility model relates to the field of medical rubber product processing technology, specifically a molding device for medical rubber products. Background Technology

[0002] Medical rubber products are indispensable materials in the medical and health field. They are widely used in the connection parts and sealing parts of medical equipment, such as sealing gaskets for syringes and infusion sets, to ensure the normal operation and safety of the equipment.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, the inconvenience of extrusion molding will lead to a slow production process, making it impossible to complete production tasks on time, increasing production costs, and reducing the economic benefits of enterprises. At the same time, if the rubber raw material gets stuck in the equipment, it will affect its normal filling and molding in the mold, which may lead to defects such as material shortage in the product, affecting the appearance and dimensional accuracy of the product.

[0004] To address the aforementioned problems, the inventors have proposed a medical rubber product molding device to solve these problems. Summary of the Invention

[0005] To address the problems of inconvenience in extruding rubber raw materials and the inability to prevent rubber raw materials from overflowing and getting stuck, this utility model provides a molding device for medical rubber products.

[0006] To solve the above problems, the present invention adopts the following solution: a medical rubber product molding device, comprising a base plate, an anti-jamming device fixedly connected to one side of the top surface of the base plate, and an extrusion device fixedly connected to the other side of the top surface of the base plate. The extrusion device comprises two supports, with a roller rotatably connected between the lower ends of the supports. A motor is fixedly connected to one side of one of the supports, and the output end of the motor extends into the support and is fixedly connected to the roller. An annular groove is formed on the outer surface of the roller, and a connecting rod is provided on the inner wall of the annular groove. A push rod is fixedly connected to the top end of the connecting rod, and an extrusion plate is fixedly connected to the other end of the push rod.

[0007] As a preferred technical solution of this application, the anti-jamming device includes a plurality of first support rods and a plurality of second support rods. The top end of the first support rod is fixedly connected to a housing, and the top surface of the second support rod is fixedly connected to a storage tank. The upper end of the storage tank is connected to a funnel. A baffle is fixedly connected to one side of the extrusion plate, and a plurality of shaping grooves are opened on one side of the housing.

[0008] With the above technical solution, when the extrusion plate moves toward the storage tank, the baffle enters the storage tank through the through groove. When the shell and the storage tank are connected, the sealing ring is embedded in the sealing groove to play a sealing role and prevent the rubber raw material from leaking. The extrusion plate squeezes the rubber raw material into the shaping groove of the shell, and the baffle enters the inside of the storage tank. The baffle enters the storage tank through the through groove, which can effectively prevent the rubber raw material from overflowing and avoid the raw material from getting stuck.

[0009] As a preferred technical solution of this application, the lower end of the connecting rod is in contact with the inner wall of the annular groove.

[0010] With the above technical solution, when the drum rotates, the annular groove on the drum causes the connecting rod to move up and down.

[0011] As a preferred technical solution of this application, one end of the push rod is fixedly connected to a limiting plate.

[0012] The above technical solution restricts the movement of the push rod by limiting the position plate.

[0013] As a preferred technical solution of this application, a through groove is provided on one side of the storage tank for use with a baffle.

[0014] With the above technical solution, the baffle enters the storage tank through the channel.

[0015] As a preferred technical solution of this application, a sealing ring is provided on one side of the shell, and a sealing groove is provided on one side of the storage tank to cooperate with the sealing ring.

[0016] With the above technical solution, when the shell and the storage tank are connected, the sealing ring is embedded in the sealing groove, which plays a sealing role and prevents the leakage of rubber raw materials.

[0017] The technical effects of this utility model are as follows:

[0018] This invention utilizes the rotation of a roller, and the shape of the annular groove causes the connecting rod that is in contact with it to move up and down. Its lower end is in contact with the inner wall of the annular groove. When the roller rotates, the annular groove on the roller causes the connecting rod to move up and down, which in turn drives the push rod and the extrusion plate to reciprocate. The extrusion plate moves towards the storage tank, thereby achieving the purpose of effectively extruding and molding rubber raw materials.

[0019] This invention uses a sealing ring embedded in a sealing groove to achieve a sealing effect and prevent leakage of rubber raw materials. The extrusion plate squeezes the rubber raw materials into the shaping groove of the shell, and the baffle enters the storage tank through the through groove, thereby effectively preventing the rubber raw materials from overflowing and avoiding material jamming.

Detailed Implementation

[0025] 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.

[0026] Example: Figure 1-4 As shown, this utility model provides a molding device for medical rubber products, including a base plate 1, an anti-jamming device 3 fixedly connected to one side of the top surface of the base plate 1, and an extrusion device 2 fixedly connected to the other side of the top surface of the base plate 1.

[0027] The extrusion device 2 includes two supports 21, with a roller 22 rotatably connected between the lower ends of the supports 21. A motor 23 is fixedly connected to one side of one of the supports 21. The output end of the motor 23 extends into the support 21 and is fixedly connected to the roller 22. An annular groove 24 is formed on the outer surface of the roller 22. A connecting rod 25 is provided on the inner wall of the annular groove 24. The lower end of the connecting rod 25 fits against the inner wall of the annular groove 24. A push rod 26 is fixedly connected to the top end of the connecting rod 25. A limit plate 27 is fixedly connected to one end of the push rod 26, and an extrusion plate 28 is fixedly connected to the other end of the push rod 26.

[0028] As the roller 22 rotates, the shape of the annular groove 24 causes the connecting rod 25, which is in contact with it, to move up and down. Its lower end is in contact with the inner wall of the annular groove 24. When the roller 22 rotates, the annular groove 24 on the roller 22 causes the connecting rod 25 to move up and down, which in turn drives the push rod 26 and the extrusion plate 28 to reciprocate. The extrusion plate 28 moves toward the storage tank 33, which can effectively extrude and mold the rubber raw material.

[0029] The anti-jamming device 3 includes multiple first support rods 30 and multiple second support rods 31. The top of the first support rod 30 is fixedly connected to a housing 32, and the top surface of the second support rod 31 is fixedly connected to a storage tank 33. A sealing ring 34 is provided on one side of the housing 32, and a sealing groove 35 that cooperates with the sealing ring 34 is provided on one side of the storage tank 33. A funnel 36 is connected to the upper end of the storage tank 33. A baffle 37 is fixedly connected to one side of the extrusion plate 28, and a through groove 38 that cooperates with the baffle 37 is provided on one side of the storage tank 33. Multiple shaping grooves 39 are provided on one side of the housing 32.

[0030] When the shell 32 and the storage tank 33 are connected, the sealing ring 34 is embedded in the sealing groove 35 to seal and prevent the rubber material from leaking. The extrusion plate 28 extrudes the rubber material into the shaping groove 39 of the shell 32. The baffle 37 enters the interior of the storage tank 33 and enters the storage tank 33 through the through groove 38, which can effectively prevent the rubber material from overflowing and avoid the material from getting stuck.

[0031] The working principle of the medical rubber product molding device in this embodiment is as follows: rubber raw material is added to storage tank 33 through funnel 36. After the motor 23 is started, its output end drives the roller 22 to rotate. As the roller 22 rotates, the shape of the annular groove 24 causes the connecting rod 25 that is in contact with it to move up and down. Its lower end is in contact with the inner wall of the annular groove 24. When the roller 22 rotates, the annular groove 24 on the roller 22 causes the connecting rod 25 to move up and down, thereby driving the push rod 26 and the extrusion plate 28 to reciprocate. The extrusion plate 28 moves towards the storage tank 33, thereby achieving the purpose of effectively extruding and molding the rubber raw material.

[0032] When the extrusion plate 28 moves toward the storage tank 33, the baffle 37 enters the storage tank 33 through the through groove 38. When the shell 32 and the storage tank 33 are connected, the sealing ring 34 is embedded in the sealing groove 35 to seal and prevent the rubber material from leaking. The extrusion plate 28 extrudes the rubber material into the shaping groove 39 of the shell 32, and the baffle 37 enters the interior of the storage tank 33. The baffle 37 enters the storage tank 33 through the through groove 38, thereby effectively preventing the rubber material from overflowing and avoiding the material from getting stuck.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
