Description

Technical Field

[0001] This utility model relates to the field of polycarbonate sheet production technology, specifically to an extrusion die for producing polycarbonate sheets. Background Technology

[0002] Polycarbonate sheet, also known as polyester fiber polycarbonate sheet, is made of high-performance engineering plastic polycarbonate or polycarbonate processed into polycarbonate. Characteristics: Impact resistant, unbreakable, with strength hundreds of times greater than tempered glass and acrylic sheets; tough, safe, and offers excellent anti-theft and bulletproof performance. Can be arched and bent: Excellent processability and high plasticity; can be bent into arches, semi-circles, etc., according to the actual needs of the construction site. In the production process of polycarbonate sheets, extrusion molds are mostly used to extrude the polycarbonate sheet material from the mold.

[0003] A polycarbonate sheet extrusion mold with publication number CN 221540580 U is disclosed. The mold includes a housing with holes at its top corners, through which a feeding assembly is connected. Sliding grooves are formed on both sides of the outer surface of the housing, and sliding blocks are slidably connected to both sides of each groove. The four sliding blocks are grouped in pairs, and a moving rod is fixedly connected to the opposite side of each sliding block. A circular hole is formed on one side of the top of each moving rod. This invention, through the arrangement of sliding blocks, moving rods, limiting rods, limiting heads, and positive and negative threaded rods, allows for the production of polycarbonate sheets of varying thicknesses. An external power supply is connected to a servo motor, and the servo motor's output shaft rotates, driving the positive and negative threaded rods. The rotation of these rods, in turn, moves the moving rods on both sides of the outer surface, causing them to move up and down, adjusting the size of the housing's discharge port.

[0004] However, the above-mentioned mold still has some shortcomings in use. It is not equipped with a cooling component, so the extruded sheet can only cool naturally, resulting in delayed cooling, low efficiency, and inconvenience for subsequent processing. At the same time, it lacks a cutting component, making it impossible to quickly cut the polycarbonate sheet according to the production situation, which is inconvenient to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an extrusion mold for producing polycarbonate endurance sheets. It solves the problems of the lack of a cooling component, which means that the extruded sheets can only cool naturally, resulting in delayed cooling, low efficiency, and inconvenience for subsequent processing. In addition, the lack of a cutting component makes it impossible to quickly cut the endurance sheets according to production conditions, making it inconvenient to use.

[0006] This utility model provides the following technical solution: a polycarbonate endurance board production extrusion mold, including a base plate, a material box fixedly installed on the upper surface of the base plate, a processing box fixedly installed at the front end of the material box, an opening at the rear end of the material box and a support frame fixedly installed thereon, an electric push rod fixedly installed on the surface of the support frame, a push plate fixedly connected to the output end of the electric push rod, and the outer ring of the push plate being in contact with the inner wall of the material box;

[0007] Both the front end of the material box and the front end of the processing box have discharge ports. The upper surface of the processing box has a threaded hole, and a lead screw is threaded into the inside of the threaded hole. A limit plate is rotatably installed at the bottom end of the lead screw. A baffle is fixedly connected to the surface of the limit plate. Both the limit plate and the baffle are in contact with the front surface of the material box. A cutting assembly and a cooling assembly are installed inside the processing box.

[0008] Preferred technical solution 1: Two limiting grooves are formed on the upper surface of the material box, and a limiting rod is slidably sleeved inside each of the two limiting grooves. Both limiting rods are fixedly connected to the limiting plate.

[0009] Preferred technical solution 2: The cutting assembly includes a screw rotatably installed inside the processing box, a threaded sleeve is threaded onto the surface of the screw, a laser cutting head is installed on the lower surface of the threaded sleeve, a slide rod is fixedly installed inside the processing box, a slide sleeve is slidably fitted onto the surface of the slide rod, and the slide sleeve is fixedly connected to the threaded sleeve.

[0010] Preferred technical solution 3: The cooling component includes a slot formed on the processing box, a plurality of fans are fixedly installed inside the slot, and a mounting frame is bolted to the upper surface of the processing box, with a dust filter fixedly installed inside the mounting frame.

[0011] Preferred technical solution four: A drive motor is fixedly installed on the surface of the processing box, and the output end of the drive motor extends into the interior of the processing box and is fixedly connected to the screw.

[0012] Preferred technical solution five: The upper surface of the material box is connected to a feed pipe, and the feed pipe is connected to an external feed assembly.

[0013] Compared with existing technologies, this utility model provides a polycarbonate endurance sheet extrusion mold with the following advantages: In use, raw materials enter the material box through the feed pipe. Then, the extension of the electric push rod drives the push plate to move, pushing the material from the opening of the material box. The opening, in conjunction with the baffle and limiting plate, extrudes the raw material into a sheet shape. A fan then rapidly cools and shapes the extruded endurance sheet. A dust filter prevents external dust from entering. After cooling, the endurance sheet extends through the opening of the processing box. When cutting is required, the electric push rod stops, and the rotation of the drive motor drives the screw, which in turn moves the laser cutting head. The laser cutting head cuts the cooled and shaped endurance sheet quickly and easily. Simultaneously, rotating the lead screw moves the limiting plate and baffle up and down, controlling the thickness of the extruded endurance sheet. This mold is highly versatile. During use, the thickness of the formed endurance sheet can be adjusted, and it can cool and shape the sheet quickly. It can also be quickly cut according to actual needs, making it easy to use.

[0019] Example 1: An extrusion mold for producing polycarbonate endurance board includes a base plate 1, a material box 2 fixedly installed on the upper surface of the base plate 1, a processing box 3 fixedly installed at the front end of the material box 2, an opening at the rear end of the material box 2 and a support frame 4 fixedly installed thereon, an electric push rod 5 fixedly installed on the surface of the support frame 4, a push plate 6 fixedly connected to the output end of the electric push rod 5, and the outer ring of the push plate 6 being in contact with the inner wall of the material box 2.

[0020] Both the front end of the material bin 2 and the front end of the processing box 3 are provided with discharge ports. The upper surface of the processing box 3 is provided with a threaded hole 7. A lead screw 8 is threaded inside the threaded hole 7. A limit plate 9 is rotatably installed at the bottom end of the lead screw 8. A baffle 10 is fixedly connected to the surface of the limit plate 9. Both the limit plate 9 and the baffle 10 are in contact with the front surface of the material bin 2. A cutting component is provided inside the processing box 3. A cooling component is provided inside the processing box 3.

[0021] Example 2: The difference between this example and Example 1 is that the upper surface of the material box 2 has two limiting grooves 11, and the inside of each limiting groove 11 is slidably fitted with a limiting rod 12. Both limiting rods 12 are fixedly connected to the limiting plate 9, which facilitates the restriction of the movement of the limiting plate 9 and the baffle 10, and makes it easier to adjust the thickness of the polycarbonate sheet.

[0022] Example 3: The difference between this example and Example 1 is that the cutting assembly includes a screw 13 rotatably installed inside the processing box 3, a screw sleeve 14 threaded onto the surface of the screw 13, a laser cutting head 15 installed on the lower surface of the screw sleeve 14, a slide rod 16 fixedly installed inside the processing box 3, a slide sleeve 17 slidably fitted onto the surface of the slide rod 16, and a fixed connection between the slide sleeve 17 and the screw sleeve 14, which facilitates the cutting of the formed polycarbonate sheet.

[0023] Example 4: The difference between this example and Example 1 is that the cooling component includes a slot opened on the processing box 3, and multiple fans 18 are fixedly installed inside the slot. A mounting frame 19 is bolted to the upper surface of the processing box 3, and a dust filter 20 is fixedly installed inside the mounting frame 19, which can quickly cool and shape the extruded polycarbonate sheet.

[0024] Example 5: The difference between this example and Example 1 is that a drive motor 21 is fixedly installed on the surface of the processing box 3, and the output end of the drive motor 21 extends into the interior of the processing box 3 and is fixedly connected to the screw 13.

[0025] Example 6: The difference between this example and Example 1 is that the upper surface of the material box 2 is connected to a feed pipe 22, which is connected to an external feed assembly.

[0026] In summary, this polycarbonate sheet extrusion mold operates as follows: Raw material enters the material bin 2 through the feed pipe 22. The extension of the electric push rod 5 moves the push plate 6, which pushes the material inside the bin 2 out through the opening. The opening, in conjunction with the baffle 10 and the limiting plate 9, extrudes the raw material into a sheet shape. The fan 18 then rapidly cools and solidifies the extruded polycarbonate sheet. Simultaneously, the dust filter 20 prevents external dust from entering. After cooling, the polycarbonate sheet extends through the opening of the processing box 3. When cutting the polycarbonate sheet is required... The electric push rod 5 stops operating, and then the drive motor 21 rotates to drive the screw 13 to rotate, thereby moving the laser cutting head 15. The laser cutting head 15 cuts the cooled and formed polycarbonate sheet, which is convenient and fast. At the same time, by rotating the lead screw 8, the limiting plate 9 and the baffle 10 can be moved up and down, thereby controlling the thickness of the extruded polycarbonate sheet. It has strong applicability. When using this mold, the thickness of the formed polycarbonate sheet can be adjusted, and it can be cooled to form quickly. At the same time, it can quickly cut the polycarbonate sheet according to actual needs, which is convenient to use.
