Description

Technical Field

[0001] The utility model relates to the technical field of rubber pads, and particularly relates to a rubber shock-absorbing pad mold with polytetrafluoroethylene pasted on it. Background Technique

[0002] The rubber shock-absorbing pad is formed by the comprehensive action of various factors such as the demand for vibration and noise control, the excellent performance of rubber materials, the promotion of technological progress, and the wide range of application fields. With the continuous development of technology and the improvement of people's requirements for the quality of life, the application prospect of the rubber shock-absorbing pad will be broader. At present, in engineering equipment, rubber shock-absorbing pads are very common. The shock-absorbing pads are generally made of rubber, and the rubber shock-absorbing pad makes use of the characteristic that vulcanized rubber has high elasticity.

[0003] In the prior art, the production of vulcanized rubber pads is generally carried out by using a mold. The traditional mold adds rubber solution to the lower mold base, and then forms it under the action of high temperature and pressure between the upper mold base and the lower mold base. Since the vulcanized rubber is easy to stick to the lower mold base after the shock-absorbing pad is formed, it is difficult to demold the formed shock-absorbing pad; at the same time, after pasting the polytetrafluoroethylene film, during the forming process, the uneven tension of the rubber compound easily causes the phenomenon of the polytetrafluoroethylene film wrinkling, thus affecting the quality of the product.

[0004] Therefore, there is an urgent need for a rubber shock-absorbing pad mold that makes the formed shock-absorbing pad easy to demold and the polytetrafluoroethylene film not easy to wrinkle. Summary of the Invention

[0005] The purpose of the utility model is to provide a rubber shock-absorbing pad mold with polytetrafluoroethylene pasted on it, so as to at least solve the problems that the formed shock-absorbing pad of the existing mold is not easy to demold and the polytetrafluoroethylene film is easy to wrinkle.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A rubber shock-absorbing pad mold with polytetrafluoroethylene pasted on it includes an upper mold base, a lower mold base, a mold core, a plate core, and a plurality of stoppers connected between the upper mold base and the lower mold base. The upper mold base, the mold core, the plate core, the stoppers, and the lower mold base jointly enclose a cavity, and further includes a shaping plate for positioning the plate core, and a polytetrafluoroethylene film is pasted on the shaping plate;

[0008] The shaping plate is arranged above the plate core, modules corresponding to the side blind holes of the shock-absorbing pad are arranged on the left and right stoppers between the upper mold base and the lower mold base, a plurality of positioning pins are arranged on both the left and right sides of the lower mold base, and surplus rubber grooves and a plurality of mold-opening grooves are arranged on both the front and back sides.

[0009] Further, a plurality of movable positioning pins are arranged on the shaping plate.

[0010] Furthermore, the movable positioning pins are cross - distributed on both sides of the shaping plate.

[0011] Furthermore, the stop blocks include a left insert block, a right insert block, a front stop block and a rear stop block. The left insert block and the right insert block are arranged on the left and right sides between the upper die base and the lower die base, and the front stop block and the rear stop block are arranged on the front and rear sides between the upper die base and the lower die base.

[0012] Furthermore, a plurality of guide pins are arranged on both the left and right sides of the upper die base, and guide pin insertion holes corresponding to the guide pins are arranged on both the left insert block and the right insert block.

[0013] Furthermore, positioning pin insertion holes corresponding to the positioning pins are arranged on both the left insert block and the right insert block.

[0014] Furthermore, the guide pin insertion holes and the positioning pin insertion holes are symmetrically arranged along the same axis of symmetry respectively.

[0015] Furthermore, positioning grooves and positioning holes are formed on both the front stop block and the rear stop block.

[0016] Furthermore, core - pulling holes are provided on both the die core and the plate core.

[0017] Furthermore, the module is arranged on the left insert block and the right insert block and is integrally formed with the left insert block and the right insert block.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. The present utility model provides a rubber shock - absorbing pad mold for pasting polytetrafluoroethylene. By arranging modules corresponding to the side blind holes of the shock - absorbing pad on the left insert block and the right insert block, the modules are inserted into the side blind holes of the shock - absorbing pad. When demolding the left insert block and the right insert block, the modules can bring out the shock - absorbing pad, thus better reducing the difficulty of demolding operation, making the formed shock - absorbing pad easy to demold, and being able to reduce costs. By arranging movable positioning pins on the shaping plate, it can avoid the problem that during actual production, due to the negligence of operators, the amount of glue is too large, the shaping plate is lifted and shifted upward, which is likely to damage the upper die base and the front and rear stop blocks.

[0029] Embodiment:

[0030] As shown in Figure 1 , this embodiment provides a rubber shock pad mold for pasting polytetrafluoroethylene, which includes an upper die base 1, a lower die base 2, a die core 7, a plate core 5, and a plurality of stoppers connected between the upper die base 1 and the lower die base 2. The upper die base 1, the die core 7, the plate core 5, the stoppers, and the lower die base 2 jointly enclose a cavity, and further includes a shaping plate 6 for positioning the plate core 5.

[0031] Furthermore, the shaping plate 6 is arranged above the plate core 5. As shown in Figure 2 , a polytetrafluoroethylene film 15 is pasted on the upper end surface of the shaping plate 6. In order to solve the problem that in actual production, due to the negligence of operators, the amount of glue is too large, the shaping plate 6 is lifted and shifted upward, which is likely to damage the upper die base 1 and the front and rear stoppers. Two movable positioning pins 14 are arranged on the shaping plate 6, which can adjust the position of the shaping plate 6 according to the amount of glue. At the same time, the shaping plate 6 can position the plate core 5, making it not easy to deform, shaping the shock pad 8, and making its surface uniform and flat, so that the polytetrafluoroethylene film 15 is not easy to be wrapped back and wrinkled.

[0032] In this embodiment, the two movable positioning pins 14 are cross-distributed on the front and rear sides of the shaping plate 6. The cross-distribution is convenient for mold removal and the surface of the shock pad 8 to be stressed evenly, reducing the wrinkling of the surface of the polytetrafluoroethylene film 15.

[0033] Furthermore, the stoppers include a left insert block 3, a right insert block 10, a front stopper 4, and a rear stopper 9. The left insert block 3 and the right insert block 10 are arranged on the left and right sides between the upper die base 1 and the lower die base 2, and the front stopper 4 and the rear stopper 9 are arranged on the front and rear sides between the upper die base 1 and the lower die base 2.

[0034] Among them, modules 17 corresponding to the side blind holes of the shock pad 8 are arranged on both the left insert block 3 and the right insert block 10, and the modules 17 are integrally formed with the left insert block 3 and the right insert block 10. The modules 17 are inserted into the side blind holes of the shock pad 8. When the left insert block 3 and the right insert block 10 are removed from the mold, the modules 17 can bring out the shock pad 8, better reducing the difficulty of mold removal operation, making the formed shock pad 8 easy to be demolded, and being able to reduce costs.

[0035] Furthermore, two guide pins are arranged on both the left and right sides of the upper die base 1, which are used for centering, guiding, and positioning at the starting position of mold closing. Guide pin insertion holes 13 corresponding to the guide pins are arranged on both the left insert block 3 and the right insert block 10.

[0036] Two positioning pins are arranged on both the left and right sides of the lower die base 2, and positioning pin insertion holes 11 corresponding to the positioning pins are arranged on both the left insert block 3 and the right insert block 10.

[0037] Both the left insert block 3 and the right insert block 10 are provided with two guide pin jacks 13 and two locating pin jacks 11, which are divided into two groups. One guide pin jack 13 and one locating pin jack 11 form a group. The guide pin jack 13 and the locating pin jack 11 are symmetrically arranged along the same axis of symmetry respectively.

[0038] Further, both the front and rear sides of the lower die base 2 are provided with excess glue grooves 16 and two mold opening grooves 12. The excess glue grooves 16 are used to collect the excess glue during the molding process, and the mold opening grooves 12 facilitate the opening of the mold, thereby ensuring the stability of the vulcanization quality, making it difficult for the shock pad 8 to adhere to the lower die base 2 and making it easy to demold the molded shock pad 8.

[0039] Both the front stop block 4 and the rear stop block 9 are provided with positioning grooves and positioning holes. The positioning grooves are used to position the board core 5, the front stop block 4 and the rear stop block 9. The positioning holes are arranged corresponding to the movable positioning pins 14 and are used to position the sizing plate 6, so as to facilitate ensuring the wall thickness between the mold core 7 and the board core 5.

[0040] Further, both the mold core 7 and the board core 5 are provided with core pulling holes, which can release the pressure during the molding process, and the surfaces of the mold core and the board core are chrome-plated for surface treatment to facilitate the demolding of the shock pad 8.

[0041] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention pertains, based on the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
