Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizing machines, in particular to a composite heating mold for a flat vulcanizing machine. Background Art

[0002] The rubber sheathing of Gray busbars requires a flat-plate vulcanizer. Its primary function is to provide the pressure and temperature required for vulcanization. Pressure is generated by a hydraulic system through a hydraulic cylinder, while temperature is provided by a heating medium (such as steam, thermal oil, or superheated water). This press is primarily used for vulcanizing flat products such as tapes, sheets, and polymers.

[0003] Common platen vulcanizer heating molds primarily consist of upper and lower mold plates. The upper mold is fixed to a hydraulic cylinder atop the press, while the lower mold is mounted on the press's platen. The molds are clamped together to form the composite material into the desired shape. Heating components are installed in the upper and lower mold plates, transferring heat to the platen via electric heating pipes or heaters, raising the composite material to the required temperature for vulcanization or curing. However, since the mold plates are often bolted directly to the platen, they are difficult to quickly disassemble and install when the mold needs to be replaced after demolding, impacting the vulcanizer's processing efficiency. Utility Model Content

[0004] In response to the above problems, the utility model proposes a composite heating mold for a flat vulcanizing machine to solve the problem that when the existing feeding device pushes the carbon brush powder, some powder will fall onto the guide rail, affecting the fit between the feeding box and the hollow track plate, and aggravating the wear of the guide rail.

[0007] Two second limit plates are provided on the side of the placement plate away from the positioning assembly, and a limit groove is provided on the side where the two second limit plates are close to each other. The limit groove and the limit plate are slidably matched. A lifting mechanism for adjusting the height of the second limit plate and a push rod structure for pushing the rubber strip on the bottom mold to demold are provided below the limit plate.

[0008] A further improvement is that: a plurality of pin grooves are provided on the upper end surface of the bottom mold, movable pins are slidably provided in the pin grooves, and the pin grooves are connected to the through holes provided on the lower end surface of the bottom mold.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] according to Figure 1 、 2 As shown in Figures 3 and 4, a composite heating mold for a flat vulcanizing machine is proposed in this embodiment, comprising a placement plate 1 and a bottom mold 3. The placement plate 1 is provided with a placement groove 2, the bottom mold 3 is slidably fitted with the placement groove 2, and the left and right sides of the bottom mold 3 are fixedly connected with first limit plates 4;

[0022] The electric heating tubes are installed inside the base mold 3 and the pressure mold. During hot pressing, heat is transferred to the base mold 3 and the rubber material placed between them through heat conduction. As the temperature rises, the combined effects of high temperature and high pressure cause the molecular chains of the polymer material, such as rubber or plastic, to undergo a cross-linking reaction. This reaction transforms the material from a linear structure to a network-like structure, thereby fixing its properties and shape.

[0023] A positioning assembly is installed on the back of the placement plate 1 to push it horizontally. The assembly is detachably connected to the placement plate 1 and is used to adjust the placement plate 1's horizontal position for loading and unloading. The positioning assembly, placement plate 1, and bottom mold 3 are designed as separate parts, making bottom mold 3 quick and easy to replace.

[0024] Two second limit plates 17 are provided on the side of the placement plate 1 away from the positioning component. A limit groove 18 is provided on the side where the two second limit plates 17 are close to each other. The limit groove 18 slides with the first limit plate 4. A lifting mechanism for adjusting the height of the second limit plate 17 and a push rod structure for pushing the rubber strip on the bottom mold 3 to be demolded are provided below the second limit plate 17.

[0025] During demolding, the positioning mechanism will push the placement plate 1 between the two second limit plates 17, and the first limit plate 4 on the side of the bottom mold 3 will be stuck in the limit groove 18 on the second limit plate 17. The lifting mechanism pushes the limit groove 18 up, so that the bottom mold 3 and the first limit plate 4 can be automatically separated. When the placement plate 1 is moved away, the ejector structure rises to eject the mold material on the bottom mold 3.

[0026] It is worth further explaining that the upper end surface of the bottom mold 3 is provided with a plurality of pin slots 5, in which movable pins 6 are slidably disposed. The pin slots 5 are aligned with the through-holes provided on the lower end surface of the bottom mold 3. After the mold material is formed, the ejector structure pushes the movable pins 6 in the bottom mold 3 upward along the pin slots 5. As the movable pins 6 rise, they eject the mold material from the bottom mold 3, completing the demolding.

[0027] It should be noted that the width of the pin slot 5 is greater than the diameter of the perforation, so as to ensure that the movable pin 6 does not fall off from the bottom of the bottom mold 3.

[0028] About positioning components:

[0029] The positioning assembly includes a hydraulic push rod 9, the output end of which is fixedly connected to a clamping block 10. A slot 7 is provided on the side of the placement plate 1 facing the clamping block 10, which mates with the clamping block 10. The clamping block 10 is equipped with a fixing bolt, which is threadedly connected to a fixing hole 8 provided inside the slot 7. The mounting end of the hydraulic push rod 9 is fixed to the frame of the plate vulcanizer. When closing the mold, the placement plate 1 is pushed onto the table of the plate vulcanizer. When removing the placement plate 1 for replacement, the fixing bolt 11 on the clamping block 10 is unscrewed from the fixing hole 8 in the slot 7.

[0030] The lifting mechanism and the jack structure are both mounted on the base 12. Specifically, the lifting mechanism includes the base 12, and at least two second hydraulic rods 16 are provided at the upper end of the base 12. The mounting ends of the second hydraulic rods 16 are fixedly connected to the left and right sides of the base 12, and the output ends of the second hydraulic rods 16 are fixedly connected to the second limit plates 17. The lifting and lowering of the jacking plate 14 is controlled by the second hydraulic rods 16.

[0031] Specifically, the push rod structure includes a lifting plate 14 and at least one first hydraulic lever 13. The lifting plate 14 is placed above the base 12. The output end of the first hydraulic lever 13 is fixedly connected to the lifting plate 14. The mounting end of the first hydraulic lever 13 is fixedly connected to the base 12. The upper end surface of the lifting plate 14 is provided with a plurality of cylindrical pins 15. The cylindrical pins 15 are fixedly connected to the lifting plate 14. Each cylindrical pin 15 slides with each perforation. During demoulding, the second limiting plate 17 is at the same height as the first limiting plate 4. After the placement plate 1 is removed from above the lifting plate 14, the first hydraulic lever 13 pushes the lifting plate 14 upward. After the lifting plate 14 rises, it fits with the bottom mold 3. The cylindrical pins 15 at the upper end of the lifting plate 14 are inserted into the perforations. By pushing the movable pin 6 upward, the mold material is removed from the bottom mold 3.

[0032] Working principle:

[0033] The electric heating tube is installed inside the bottom mold 3 and the pressure mold. During hot pressing, the heat is transferred to the bottom mold 3 and the rubber material placed therebetween by heat conduction. During demoulding, the positioning mechanism will push the placement plate 1 between the two second limit plates 17, and the first limit plate 4 on the side of the bottom mold 3 will be stuck in the limit groove 18 on the second limit plate 17. The lifting mechanism pushes the limit groove 18 up, which can automatically separate the bottom mold 3 from the first limit plate 4. When the placement plate 1 is removed, the ejector structure rises and ejects the mold material on the bottom mold 3. The positioning component adjusts the horizontal position of the placement plate 1 for loading and unloading. The positioning component, placement plate 1 and bottom mold 3 adopt a split design, and the bottom mold 3 is quick and convenient to replace.
