Depending on the usage environment and performance requirements, common materials for take-up rollers include polyethylene, polypropylene, polyvinyl chloride, polystyrene, and polycarbonate. Take-up rollers requiring high strength and wear resistance can be made of PC material; take-up rollers requiring lower cost and a certain degree of flexibility can be made of PP material.

[0003] However, in the prior art, the components of the winding roller mold are usually connected by fixing bolts, which requires workers to use various tools to turn the fixing bolts during installation and disassembly, resulting in increased working time. In order to solve the problem of cumbersome installation and disassembly in the prior art, this application sets up plug-in components to quickly connect the components and improve work efficiency. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0004] The aforementioned background technology addresses the shortcomings and defects of existing technologies, such as inconvenience in installation and disassembly, which affect work efficiency.

[0005] This utility model discloses a winding roller mold, including a base, a housing, a pressure plate on the upper end of the housing, a mold body inside the housing, a fixing block between the housing and the pressure plate, a fixing hole on the fixing block, a fixing plate on the upper surface of the pressure plate, the fixing plate being inserted into the fixing hole, the end of the fixing hole closest to the fixing plate being chamfered, and a driving assembly between the fixing plate and the pressure plate.

[0011] Furthermore, the elastic component includes a spring, which is disposed inside the second housing. A telescopic rod is disposed inside the spring, and the two ends of the telescopic rod are respectively mounted on the second housing and the push plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a fixing block, cover plate, screw, drive rod, bevel gear and other components, allows the fixing block at the upper end of the outer shell to pass through the pressure plate during installation, thereby positioning the pressure plate and the outer shell. Then, through the cooperation between the drive rod component, bevel gear component and cover plate, the drive rod is adjusted to rotate, thereby driving the bidirectional screw to rotate.

[0021] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0022] Please see Figure 1 , Figure 2 , Figure 3 This utility model discloses a winding roller mold, including a base 1, a housing 2 on the base 1, the housing 2 being connected to the base 1 by fixing bolts, a pressure plate 3 on the upper end of the housing 2, a mold body on the inner side of the housing 2, a fixing block 4 between the housing 2 and the pressure plate 3, a fixing hole 5 on the fixing block 4, a fixing plate 6 on the upper end face of the pressure plate 3, the fixing plate 6 being inserted into the fixing hole 5, the end of the fixing hole 5 and the fixing plate 6 being chamfered, and a driving assembly between the fixing plate 6 and the pressure plate 3.

[0023] Before injection molding, the mold body is heated to a certain temperature to bring the mold to a suitable working temperature, which is conducive to the filling and molding of the plastic melt. Then, the plastic raw material is added to the barrel of the injection molding machine. Through heating and screw rotation, the plastic particles are gradually melted to form a uniform plastic melt. The molten plastic melt is then injected into the cavity of the mold body under a certain pressure and speed. After injection, a certain pressure is maintained for a period of time to fully compact the plastic melt in the mold cavity, thereby improving the density and dimensional accuracy of the take-up roller.

[0024] like Figure 2 As shown, the pressure plate 3 includes a bidirectional screw 7, which is rotatably mounted on the pressure plate 3. The bidirectional screw 7 is threadedly connected to the fixing plate 6. The bidirectional screw 7 is controlled to rotate, and the bidirectional screw 7 drives the two fixing plates 6 to move relative to each other. Through the mutual cooperation between the fixing plates 6 and the fixing block 4, the two positions are fixed at one time, thereby improving the fixing effect.

[0025] In this embodiment, a cover plate 8 is provided above the bidirectional screw 7. The cover plate 8 is connected to the pressure plate 3 by fixing bolts. A drive rod 9 is rotatably installed on the cover plate 8. Both the drive rod 9 and the bidirectional screw 7 are equipped with bevel gears 10. The bevel gears 10 on the drive rod 9 and the bevel gears 10 on the bidirectional screw 7 mesh and drive each other. While the fixed plate 6 moves, it interacts with the inside of the cover plate 8, thereby restricting the movement direction of the fixed plate 6 and ensuring accurate connection between the fixed plate 6 and the fixing hole 5.

[0026] A baffle 11 is provided on the side of the fixing block 4 away from the fixing plate 6. The baffle 11 is triangular and is installed on the pressure plate 3 by fixing bolts. The baffle 11 is slidably disposed with the fixing block 4. When the fixing plate 6 is inserted into the fixing hole 5, it will apply a pushing force to the fixing block 4. The baffle 11 supports the fixing block 4, thereby preventing the fixing block 4 from tilting.

[0027] See Figure 3 As shown, a sliding groove 17 is provided at the upper end of the fixed plate 6, and the cover plate 8 is slidably disposed with the sliding groove 17, which increases the contact area between the cover plate 8 and the fixed plate 6 and improves the stability of the fixed plate 6 when it moves.

[0028] Combination Figure 1 , Figure 4 As shown, a limiting block 12 is installed on the upper surface of the pressure plate 3. The limiting block 12 is connected to the pressure plate 3 by fixing bolts. A second outer shell 13 is provided between the limiting block 12 and the pressure plate 3. A limiting rod 16 is provided between the second outer shell 13 and the limiting block 12. The limiting rod 16 is threadedly connected to the second outer shell 13. The lower end of the second outer shell 13 passes through the pressure plate 3. A push plate 14 is provided at the lower end of the second outer shell 13. An elastic component is provided between the push plate 14 and the second outer shell 13.

[0029] In this embodiment, the elastic component includes a spring 15, which is disposed inside the outer casing 13. A telescopic rod is disposed inside the spring 15, and the two ends of the telescopic rod are respectively installed on the outer casing 13 and the push plate 14. When the pressure plate 3 is installed on the outer casing 2, the push plate 14 retracts into the outer casing 13 and compresses and stores the spring 15. When the fixation between the pressure plate 3 and the outer casing 2 is released, the spring 15 releases the force and pushes the outer casing 13 to move, and the outer casing 13 drives the pressure plate 3 to move, so that the pressure plate 3 and the outer casing 2 are automatically separated.

[0030] The implementation principle is as follows: During installation, the mold body is placed inside the outer shell 2 and secured with fixing bolts. Then, the pressure plate 3 is placed on the outer shell 2, so that the fixing plate 6 passes through the pressure plate 3. Next, the operator rotates the drive rod 9, which drives the double-ended screw 7 to rotate through the meshing of the bevel gears 10. The double-ended screw 7 pushes the fixing plate 6 to move, and the fixing plate 6 is inserted into the fixing hole 5. At the same time, the chamfering action of the fixing hole 5 causes the pressure plate 3 to be pressed and fixed between the outer shell 2. By controlling the drive rod 9 to rotate in the opposite direction, the fixing plate 6 is separated from the fixing hole 5, and the fixation between the pressure plate 3 and the outer shell 2 is released.

[0031] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
