Description

Technical Field

[0001] This utility model relates to the field of sealing strip production technology, and in particular to an opening and closing mold structure for the production of cylindrical sealing strips. Background Technology

[0002] Cylindrical sealing strips are widely used for sealing the filter chambers of chamber filter presses. During the vulcanization process, the upper and lower molds need to be continuously closed and opened. The upper mold has positioning holes, and the lower mold has positioning pins. The assembly of the upper and lower molds is completed by inserting the positioning pins and positioning holes. First, the raw material strip is placed in the forming groove of the lower mold. Then, the upper mold is manually lifted and closed with the lower mold. The closed upper and lower molds are then moved into the vulcanization molding machine for heating and pressurization. After vulcanization, the upper and lower molds are removed from the vulcanization molding machine. The upper mold is first pried open with a tool to separate it from the lower mold. Then, the worker lifts the upper mold off and sets it aside. The processed cylindrical sealing strip is then removed, a new raw material strip is placed in, the upper and lower molds are closed again, and the strip is sent back into the vulcanization molding machine.

[0003] The above production process has the following shortcomings: First, the upper mold needs to be manually lifted during both mold closing and mold opening. The upper mold itself is relatively heavy, so the labor intensity of workers is high during the mold closing and mold opening process. In addition, tools are needed to pry the upper mold when opening the mold, which is inconvenient to operate.

[0004] Based on the above technical problems, the inventor proposed an opening and closing mold structure for the production of cylindrical sealing strips. Both mold closing and opening are completed by mechanical structure, eliminating the manual lifting process and effectively reducing the labor intensity of workers; moreover, no additional tools are needed when opening the mold, making the operation convenient. Summary of the Invention

[0005] This utility model addresses the shortcomings of existing technologies by providing an opening and closing mold structure for the production of cylindrical sealing strips.

[0006] This utility model is achieved through the following technical solution: It provides an opening and closing mold structure for producing cylindrical sealing strips, including an operating table, a conveying mechanism, and a mounting frame. The operating table is located on one side of the inlet of the vulcanizing molding machine. The conveying mechanism is located on the top surface of the operating table, and the mounting frame is mounted above the conveying mechanism. The conveying mechanism is used for conveying the upper and lower molds. A limiting component for limiting the lower mold is provided on the conveying mechanism, and a lifting and lowering drive mechanism for driving the upper mold to rise and fall is provided on the mounting frame. The lower mold is limited by the limiting mechanism. When the lifting and lowering drive mechanism pulls up the upper mold, the upper and lower molds separate. When the upper mold falls back down, the upper and lower molds close again.

[0007] Preferably, the conveying mechanism is a non-powered roller conveyor, which includes two side frames and rollers rotatably mounted between the two side frames.

[0008] Preferably, both sides of the frame are connected to the control panel by bolts.

[0009] Preferably, support legs are provided at all four corners of the bottom surface of the operating table.

[0010] Preferably, the limiting component includes two L-shaped limiting plates, which are respectively installed on the two side frames and arranged opposite to each other.

[0011] Preferably, the lower mold has ear plates on its two opposite side walls, each corresponding to one of the L-shaped limiting plates. When the ear plate moves to the position of the L-shaped limiting plate, the L-shaped limiting plate limits the ear plate, preventing the lower mold from moving up and down during mold opening.

[0012] Preferably, to ensure accurate positioning of the L-shaped limiting plate against the ear plate, positioning rods are installed on both sides of the machine frame, each positioning rod being threadedly connected to a threaded hole on the machine frame. When the ear plate touches the positioning rod, the lower mold stops, at which point the ear plate has just moved below the L-shaped limiting plate and is positioned by it.

[0013] Preferably, a handle is installed on the front side wall of the lower mold to facilitate its movement.

[0014] Preferably, the mounting frame includes a crossbeam and two columns. The upper ends of the two columns are connected by the crossbeam, and the lower end of each column is fixed to the operating table. The two columns are located on both sides of the conveying mechanism.

[0015] Preferably, the lifting and lowering drive mechanism includes a cylinder mounted on a crossbeam, a fixing plate installed at the end of the cylinder piston rod, and an electromagnetic chuck installed below the fixing plate. The upper mold is made of metal. When the electromagnetic chuck is energized, it can attract the upper mold and lift it under the drive of the cylinder.

[0016] The beneficial effects of this utility model are as follows:

[0017] This application completes mold closing and opening operations through the cooperation of a conveying mechanism, a limiting component, and a lifting and lowering drive mechanism. Both mold closing and opening are completed by mechanical structure, eliminating the need for manual handling and effectively reducing the labor intensity of workers; moreover, no additional tools are required when opening the mold, making the operation convenient.

[0027] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0028] like Figure 1-7 As shown, this utility model includes an operating platform 1, a conveying mechanism, and a mounting frame. The operating platform 1 is located on one side of the inlet 8 of the vulcanizing molding machine 6. The conveying mechanism is located on the top surface of the operating platform 1, and the mounting frame is mounted above the conveying mechanism. The conveying mechanism is used for conveying the upper mold 9 and the lower mold 10. A limiting component for limiting the lower mold 10 is provided on the conveying mechanism, and a lifting and lowering drive mechanism for driving the upper mold 9 to rise and fall is provided on the mounting frame. By limiting the lower mold 10 through the limiting mechanism, when the lifting and lowering drive mechanism pulls up the upper mold 9, the upper mold 9 and the lower mold 10 separate. When the upper mold 9 falls back down, the upper mold 9 and the lower mold 10 close again.

[0029] In this embodiment, the conveying mechanism is a non-powered roller conveyor, which includes two side frames 3 and rollers 5 rotatably mounted between the two side frames 3. This rotatable mounting is a conventional bearing mounting. Furthermore, both side frames 3 are connected to the operating table 1 by bolts.

[0030] In this embodiment, support legs 7 are provided at the four corners of the bottom surface of the operating table 1.

[0031] In this embodiment, the limiting component includes two L-shaped limiting plates 4, which are respectively mounted on the two side frames 3 and arranged opposite to each other. Ear plates 11, corresponding to each L-shaped limiting plate 4, are provided on the two opposite side walls of the lower mold 10. When the ear plate 11 moves to the position of the L-shaped limiting plate 4, the L-shaped limiting plate 4 limits the ear plate 11, preventing the lower mold 10 from moving up and down during mold opening. Furthermore, to ensure accurate limiting of the ear plate 11 by the L-shaped limiting plate 4, positioning rods 2 are respectively installed on the two side frames 3, each positioning rod 2 being threadedly connected to a threaded hole on the frame 3. When the ear plate 11 touches the positioning rod 2, the lower mold 10 stops, at which point the ear plate 11 has just moved below the L-shaped limiting plate 4 and is limited by it.

[0032] In this embodiment, a handle 12 is installed on the front side wall of the lower mold 10 to facilitate movement of the lower mold 10.

[0033] In this embodiment, the mounting frame includes a crossbeam 13 and two columns 15. The upper ends of the two columns 15 are connected by the crossbeam 13, and the lower end of each column 15 is fixed to the operating table 1. The two columns 15 are located on both sides of the conveying mechanism.

[0034] In this embodiment, the lifting and lowering drive mechanism includes a cylinder 14 mounted on the crossbeam 13, a fixing plate 16 mounted at the end of the piston rod of the cylinder 14, and an electromagnetic chuck 17 mounted below the fixing plate 16. The electromagnetic chuck 17 adopts an existing structure. The electromagnetic chuck 17 is connected to the fixing plate 16 via a pin. Furthermore, the cylinder 14 is connected to an air pump, using an existing connection method. The upper mold 9 is made of metal. When the electromagnetic chuck 17 is energized, it can attract the upper mold 9 and achieve lifting and lowering under the drive of the cylinder 14.

[0035] In practical use, the lower mold 10 is first limited by the limiting component. The upper mold 9 is then raised using the lifting and lowering drive mechanism. After the upper mold 9 and the lower mold 10 separate, the raw material strip is placed into the lower mold 10. Then, the upper mold 9 falls down to complete the mold closing. After the mold closing, the worker first cuts off the power to the electromagnetic chuck 17 and then raises it to its original position. The upper mold 9 and the lower mold 10 are pushed into the vulcanizing molding machine 6 using a non-powered roller conveyor. After vulcanization, the upper mold 9 and the lower mold 10 are removed from the vulcanizing molding machine 6. After mold separation, the processed cylindrical sealing strip can be taken out.

[0036] This application completes mold closing and opening operations through the cooperation of a conveying mechanism, a limiting component, and a lifting and lowering drive mechanism. Both mold closing and opening are completed by mechanical structure, eliminating the need for manual handling and effectively reducing the labor intensity of workers; moreover, no additional tools are required when opening the mold, making the operation convenient.
