Description

Technical Field

[0001] This utility model relates to a novel vulcanizing mold for building shock absorbers, belonging to the field of vulcanizing molds. Background Technology

[0002] Currently, viscous dampers are widely used in buildings to counteract the energy generated by vibrations and ensure the safety of buildings during earthquakes and wind-induced vibrations. Rubber has both elastic solid properties and viscous fluid properties, and using suitable rubber and a suitable structure to make dampers can achieve better shock absorption and damping effects.

[0003] Rubber dampers require the use of a special mold in conjunction with a vulcanizing machine during the vulcanization process. The special mold has a complex structure and high cost, which is not conducive to product promotion. Therefore, it is necessary to design a new type of vulcanization mold to be used in conjunction with a flat vulcanizing machine. Utility Model Content

[0004] The purpose of this invention is to design a novel mold structure for a rubber damper, suitable for flat vulcanizing machines.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel vulcanizing mold for building shock absorbers, comprising an upper mold and a lower mold that are assembled together, with a mold cavity between the upper mold and the lower mold. Within the mold cavity are a limiting mold A, a limiting mold B, an upper constraint steel plate, a lower constraint steel plate, rubber elastomer A, rubber elastomer B, a connecting plate, and a mold core. The upper constraint steel plate is fitted to the upper mold, and the lower constraint steel plate is fitted to the lower mold. Between the upper and lower constraint steel plates are the rubber elastomer A, the rubber elastomer B, the connecting plate, and the mold core. The mold core is located at the center position. Rubber elastomer A is provided on both the upper left and right sides, connecting plates are provided on both the middle left and right sides, and rubber elastomer B is provided on both the lower left and right sides. The limiting mold A is located on both sides of the upper constraint steel plate and the rubber elastomer A, and the limiting mold B is located on both sides of the lower constraint steel plate and the rubber elastomer B.

[0006] Furthermore, the two ends of the connecting plate are located between the limiting mold A and the limiting mold B.

[0007] Furthermore, the lower constraint steel plate is fixed by the groove at the bottom of the lower mold, and the upper constraint steel plate is fixed by the combined action of the lower mold, the upper mold, and the limiting mold A.

[0008] Furthermore, the upper surface of the lower mold is provided with four stepped grooves, which are, from bottom to top: steel plate groove, lower limit mold groove, connecting plate groove and upper limit mold groove.

[0009] Furthermore, the side end faces of the steel plate groove and the connecting plate groove are straight, while the side end faces of the lower limit mold groove and the upper limit mold groove are inclined.

[0010] Furthermore, the lower surface of the upper mold has an upper mold limiting groove, and the side end face of the upper mold limiting groove is an inclined surface.

[0011] Furthermore, the upper mold has positioning pin grooves at both ends, and the lower mold has positioning pin holes at both ends.

[0012] Furthermore, the front and rear ends of the mold core are respectively provided with limiting mold C and limiting mold D, and the limiting mold C and limiting mold D are simultaneously located between the upper constraint steel plate and the lower constraint steel plate.

[0013] Furthermore, the limiting mold C and the limiting mold D are provided with a mold core mating groove, a connecting plate slot, an overflow groove A, an overflow groove B, a guide groove A, a guide groove B, and a pin hole.

[0014] Furthermore, the mold core has through holes and notches at both ends.

[0015] The beneficial effects of this utility model are: this mold is applicable to flat vulcanizing machines, and its vulcanization quality is high while its cost is lower than that of existing special molds. Through the cooperation of the limiting mold inclined surface and the limiting mold of the upper and lower molds, the limiting mold squeezes the rubber elastomer into the mold cavity during the mold closing process. At the same time, the limiting mold, mold core, connecting plate and constraint steel plate work together to form a closed mold cavity, which can ensure the dimensional accuracy of the rubber elastomer.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 4 As shown, a novel vulcanizing mold for building vibration dampers includes an upper mold 1, limiting molds A2, B7, C11, and D12, a mold core 6, a lower mold 10, an upper restraining steel plate 3, rubber elastomers A4 and B8, a connecting plate 5, and a lower restraining steel plate 9. The upper mold 1 and lower mold 10 are assembled together. The upper restraining steel plate 3 is attached to the upper mold, and the lower restraining steel plate 9 is attached to the lower mold. Between the upper and lower restraining steel plates 3 and 9 are the rubber elastomers A4 and B8, the connecting plate 5, and the mold core 6. The mold core 6 is located at the center. Rubber elastomers A4 are located on the left and right sides of the upper end of the mold core 6, connecting plates 5 are located on the left and right sides of the middle part, and rubber elastomers B8 are located on the left and right sides of the lower part. The limiting molds A2 and B7 are located on both sides of the upper restraining steel plate 3 and rubber elastomers A4, and the limiting molds B7 are located on both sides of the lower restraining steel plate 9 and rubber elastomers B8. The two ends of the connecting plate 5 are located between the limiting mold A2 and the limiting mold B7.

[0029] like Figure 5 The lower surface of the upper mold 1 is provided with an upper mold limiting groove 1-1, the side end face of which is an inclined surface, and the two ends of the upper mold 1 are provided with positioning pin grooves 1-2.

[0030] like Figure 6The lower mold has positioning pin holes at both ends, and four stepped grooves are formed on its upper surface, from bottom to top: steel plate groove 10-1, lower limit mold groove 10-2, connecting plate groove 10-3, and upper limit mold groove 10-4. The side end faces of steel plate groove 10-1 and connecting plate groove 10-3 are straight, while the side end faces of lower limit mold groove 10-2 and upper limit mold groove 10-4 are inclined.

[0031] like Figure 7 The end face of the limiting mold A2 is provided with an upper inclined surface 2-1 and a lower inclined surface 2-2.

[0032] like Figure 8 The end face of the limiting mold B7 is provided with a limiting mold B inclined surface.

[0033] like Figure 9 The limiting mold C and the limiting mold D are provided with a connecting plate slot 11-1, an overflow groove 11-2, an overflow groove 11-4, a guide groove 11-3, a guide groove 11-5, a mold core mating groove 11-6, and a pin hole 11-7.

[0034] like Figure 10 The mold core has through holes 6-2 and notches 6-1 at both ends.

[0035] In this embodiment, the inclined surface 10-2 of the lower mold cooperates with the inclined surface of the limiting mold B. During the mold closing process, the limiting mold B compresses the rubber elastomer B8 into the mold cavity. Simultaneously, it works with the limiting mold C11, limiting mold D12, mold core 6, connecting plate 5, and lower constraint steel plate 9 to form a sealed mold cavity to ensure the dimensional accuracy of the rubber elastomer B8. The straight surface of the connecting plate groove is used to limit the left-right and up-down positions of the connecting plate 5. The inclined surface of the upper limiting mold groove cooperates with the upper inclined surface 2-1 of the limiting mold A, and the lower inclined surface 2-2 of the limiting mold A cooperates with the inclined surface of the upper mold limiting groove. During the mold closing process, the limiting mold compresses the rubber elastomer A4 into the mold cavity. Simultaneously, it works with the upper constraint steel plate 3, connecting plate 5, mold core 6, limiting mold C11, and limiting mold D12 to form a sealed mold cavity to ensure the dimensional accuracy of the rubber elastomer A4.

[0036] Excess rubber overflows from the overflow grooves 11-2 and 11-4 on the limiting mold C11 during the mold closing and vulcanization process. The guide groove 11-5 and the backflow groove 11-3 guide the overflowing rubber. The positioning pin hole 11-7 mates with the lower mold positioning pin hole to restrict the left and right position of the limiting mold. The mold core mating groove 11-6 mates with the mold core notch 6-1 to restrict the left, right, and front-back position of the mold core.

[0037] The straight surface of the upper mold limiting groove is used to limit the upper constraint steel plate. The positioning pin groove 1-2 and positioning pin hole 10-6 of the upper mold limit the mating position of the upper and lower molds through the action of positioning pins.

[0038] The mold product in this embodiment has a symmetrical structure. The process only describes the situation on one side. The other side can be assembled symmetrically.

[0039] In the process of using this utility model, first, the lower constraint steel plate 9 is placed, then the limiting mold B7 is placed, followed by the rubber elastomer B. Then, the connecting plate 5 and the limiting molds C11 and D12 are assembled and placed into the mold cavity. Next, the mold core 6 is placed and assembled with the limiting molds C11 and D12. Then, the limiting mold A2 and the rubber elastomer A4 are installed, followed by the constraint steel plate 3. Finally, the upper mold 1 is installed for mold closing and pressure vulcanization. After vulcanization, the upper mold 1 and the limiting mold A2 are removed first, then the product is taken out. During product removal, the limiting molds C11, D12, and the mold core 6 are taken out together. Then, the limiting molds C11 and D12 are removed, and the mold core 6 is extracted.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit the scope of protection of this utility model in any way, and all technical solutions obtained by equivalent substitution or other means fall within the scope of protection of this utility model.

[0041] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
