Description

Technical Field

[0001] This application relates to the field of molding die technology, and in particular to a molding die for a corrugated sidewall carrier box cavity. Background Technology

[0002] In the field of carrier tape production, the molding process of carrier tape cavities is crucial to product quality and production efficiency. Carrier tape is a strip-shaped packaging material widely used in electronic component packaging, transportation, and surface mount technology (SMT). It is usually made of materials such as plastic and paper through precision processing. According to different size specifications, carrier tape can be divided into ultra-small carrier tape, small carrier tape, and large carrier tape. Its uniformly distributed cavity structure is the core of achieving accurate positioning and protection of components, which directly affects the stability of electronic components in subsequent processing and transportation. As electronic components develop towards miniaturization and high precision, corrugated sidewall carrier tapes are increasingly widely used in high-end packaging fields due to their advantages such as enhancing component grip and reducing shaking.

[0003] However, the corrugated carrier tape requires extremely high surface cleanliness of raw materials during the pressing and molding process. Surface impurities must be thoroughly cleaned beforehand, otherwise it can easily lead to defects in the box cavity molding process and dimensional deviations. Currently, a common problem in the industry is that the molding die and the impurity cleaning structure are set up independently. This not only requires the configuration of two independent power drive systems, increasing equipment purchase and operating costs, but also occupies more production space due to the separate arrangement of the two sets of equipment, which is not conducive to the compact layout of the production line. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main objective of this application is to provide a molding die for a corrugated sidewall carrier box cavity.

[0005] The technical solution of this application is as follows: a molding die for a corrugated sidewall carrier box cavity includes a worktable, a support frame fixedly connected to the top of the worktable, two support plates arranged inside the support frame, the two support plates being axially symmetrically arranged, a die body fixedly connected to the side of the two support plates that are close to each other, a fixing sleeve a fixedly connected to one side of each support plate, a fixing sleeve b fixedly connected to one side of each die body, a limit rod slidably connected between the fixing sleeve a and the fixing sleeve b, a fixing ring fixedly connected to the outer side of each limit rod, a spring sleeved on the outer periphery of each limit rod, a fixing frame fixedly connected to the end of each of the two limit rods that are close to each other, and a cleaning roller rotatably connected inside the fixing frame.

[0006] In a preferred embodiment, the support frame is provided with a molding assembly inside. The molding assembly includes cylinders fixedly installed on both sides of the support frame, and the piston rods of the cylinders are fixedly connected to the corresponding support plates.

[0007] In a preferred embodiment, support legs are fixedly installed on the top of the workbench and on both sides of the support frame, and two L-shaped frames are fixedly connected between the tops of the two support legs.

[0008] In a preferred embodiment, a corrugated carrier belt body is placed between the two L-shaped frames, and the spring is disposed between the fixed sleeve a and the fixed ring.

[0009] In a preferred embodiment, a unwinding roller frame is installed on one side of the workbench, and all the cleaning rollers are in contact with the outer wall of the corrugated carrier belt body.

[0010] In a preferred embodiment, the cylinder on the lower end face is built into the interior of the worktable, and a cavity is formed inside the corrugated carrier belt body.

[0011] In a preferred embodiment, a controller is fixedly installed on the outside of the workbench, and the cylinder is electrically connected to the controller.

[0012] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0013] 1. In this application, the cleaning roller is always in close contact with the outer wall of the corrugated carrier belt body through the cooperation of the spring and the fixed ring. With the help of the elastic force of the spring, it can adapt to the corrugated undulation of the carrier belt surface to ensure that there are no dead corners in cleaning. When the forming component presses the corrugated carrier belt body, the cleaning and forming actions can be achieved by simply driving the support plate with a cylinder. This reduces a set of power drive devices, significantly reduces equipment purchase and operating costs, and saves production space, which is conducive to the compact layout of the production line.

[0014] 2. In this application, the piston rod of the cylinder extends and retracts, thereby pushing the mold body on the upper and lower end faces to press, thereby achieving the purpose of forming the corrugated carrier body. The L-shaped frame plays an important limiting role in the conveying of the corrugated carrier body, thereby improving the forming accuracy of the corrugated carrier body.

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1-4 A molding die for a corrugated sidewall carrier box cavity includes a worktable 1. A support frame 2 is fixedly connected to the top of the worktable 1. Two support plates 4 are arranged axially symmetrically inside the support frame 2. A mold body 5 is fixedly connected to the side of the two support plates 4 that are close to each other. A fixing sleeve a6 is fixedly connected to one side of each support plate 4. A fixing sleeve b12 is fixedly connected to one side of each mold body 5. A limit rod 7 is slidably connected between the fixing sleeve a6 and the fixing sleeve b12. A fixing ring 11 is fixedly connected to the outer side of each limit rod 7. A spring 8 is sleeved on the outer periphery of each limit rod 7. The two limit rods 7 are close to each other. One end of each component is fixedly connected to a fixing frame 9, and a cleaning roller 10 is rotatably connected inside the fixing frame 9. The cleaning roller 10 is always in close contact with the outer wall of the corrugated carrier belt body 14 through the cooperation of the spring 8 and the fixing ring 11. With the help of the elastic force of the spring 8, it can adapt to the corrugated undulation of the carrier belt surface to ensure that there are no dead corners in cleaning. When the forming component presses the corrugated carrier belt body 14, the cleaning and forming actions can be achieved by driving the support plate 4 to move through the cylinder 3. This reduces a set of power drive devices, significantly reduces equipment purchase and operating costs, and saves production space, which is conducive to the compact layout of the production line.

[0022] Specifically, the support frame 2 is equipped with a forming component inside. The forming component includes cylinders 3 fixedly installed on both sides of the support frame 2. The piston rods of the cylinders 3 are fixedly connected to the corresponding support plates 4. By extending and retracting the piston rods of the cylinders 3, the mold bodies 5 on the upper and lower end faces can be pushed to press, thereby achieving the forming purpose of the wavy carrier body 14. Support legs 15 are fixedly installed on the top of the worktable 1 and on both sides of the support frame 2. Two L-shaped frames 13 are fixedly connected between the tops of the two support legs 15. The support legs 15 can provide a relatively stable support force for the L-shaped frames 13. The L-shaped frames 13 can play an important limiting role in the conveying of the wavy carrier body 14, so as to improve the forming accuracy of the wavy carrier body 14. The wavy carrier body 14 is placed between the two L-shaped frames 13. The spring 8 is set between the fixed sleeve a6 and the fixed ring 11.

[0023] Specifically, a roll unwinding frame 16 is installed on one side of the workbench 1, and the cleaning rollers 10 are in contact with the outer wall of the corrugated carrier belt body 14 to improve the cleaning effect. The lower end cylinder 3 is built into the interior of the workbench 1, and a box cavity is formed inside the corrugated carrier belt body 14. A controller is fixedly installed on the outside of the workbench 1, and the cylinder 3 can be started and stopped by the controller. The cylinder 3 is electrically connected to the controller.

[0024] Working principle: First, before the corrugated carrier belt body 14 is operated, the cylinder 3 can be started by the controller. The extension of the piston rod of the cylinder 3 pushes the mold body 5 on the upper and lower end faces to gradually approach the corrugated carrier belt body 14. Then the cylinder 3 is stopped. At this time, the cleaning roller 10 is always in close contact with the outer wall of the corrugated carrier belt body 14 through the cooperation of the spring 8 and the fixing ring 11. With the help of the elastic force of the spring 8, it can adapt to the corrugated undulation of the carrier belt surface to ensure cleaning without dead corners. When the forming component presses the corrugated carrier belt body 14, the piston rod of the cylinder 3 can be driven to continue to extend, so that the corrugated carrier belt body 14 can be pressed and formed by the mold body 5 on the upper and lower end faces. The cleaning and forming actions can be achieved by only driving the support plate 4 with the cylinder 3, which reduces a set of power drive devices, significantly reduces the equipment purchase and operating costs, and saves production space, which is conducive to the compact layout of the production line.
