[0002] The shock insulation support is a shock insulation supporting device arranged in a building, a bridge and the like, and can effectively prevent the vibration of the lower foundation of the building from being transmitted to the upper structure. With the development of technology and the increasing attention to building shock insulation, the shock insulation support is used more and more widely in buildings. One of the shock insulation supports that is used more frequently is formed by using a corresponding mould. A plurality of metal parts are combined to form a framework, and then a rubber material is attached to the outer surface of the framework to form a preformed part.

[0031] <EMBODIMENT>

[0032] Figure 1 is a perspective view of the isolation rubber bearing mold in the embodiment, Figure 2 is a structure exploded view of the isolation rubber bearing mold in the embodiment, Figure 3 is a sectional view of the isolation rubber bearing mold in the embodiment.

[0033] As Figures 1 to 3As shown, the vibration isolation rubber bearing mold 100 (hereinafter referred to as mold 100) includes a lower mold part 10, an upper mold part 20, a mold core part 30, and a mold core part 40 that cooperate with each other. The mold core part 30 is located between the lower mold part 10 and the upper mold part 20, and its two ends are locked together when the mold is closed. The mold core part 40 passes through the middle of the lower mold part 10, the upper mold part 20, and the mold core part 30.

[0034] Figure 4 This is a perspective view of the lower mold in this embodiment.

[0035] like Figure 4 As shown, the lower mold part 10 includes a lower mold plate 11 and a plurality of lower mold locking blocks 12.

[0036] The lower template 11 is roughly rectangular in shape, with a through mold core assembly hole 111 in the middle. The middle of its surface facing the upper mold part 20 has a lower mold insert groove 112, a plurality of lower mold locking block mounting grooves 113, and a plurality of lower mold positioning grooves 114. The opposite two sides of the lower template 11 have a plurality of lower mold lifting lug holes 115.

[0037] The core assembly hole 111 is used to assemble the core part 40. Its cross-section in the thickness direction of the lower template 11 is circular. A ring of support steps 1111 is formed in the axial center of the core assembly hole 111. It has an annular support surface facing the upper mold part 20 and perpendicular to the surface direction of the lower template 11.

[0038] The lower mold groove 112 is roughly a rectangular groove, and the four corners of the rectangle are respectively formed with smaller cylindrical grooves. The groove depth of the lower mold groove 112 is less than half the thickness of the lower template 11, and its four corners are respectively located at the middle of the four sides of the lower template 11.

[0039] The lower mold locking block mounting groove 113 is a strip-shaped groove distributed on each edge of the lower mold plate 11, used to install multiple lower mold locking blocks 12. In this embodiment, there are eight lower mold locking block mounting grooves 113 in total, one on each side of each corner of the lower mold insert groove 112. The length direction of each lower mold locking block mounting groove 113 is consistent with the length direction of its side. The cross-section of the groove in the thickness direction of the lower mold plate 11 is a rectangle with rounded corners, and the bottom of the groove has a threaded hole.

[0040] The lower mold positioning groove 114 is a strip-shaped groove distributed around the lower mold insert groove 112. It is used to cooperate with the corresponding positioning block structure of the mold core 30 to achieve accurate positioning between the lower mold part 10 and the mold core 30. In this embodiment, there are eight lower mold positioning grooves 114 in total, namely two first lower mold positioning grooves 114a, two second lower mold positioning grooves 114b, and four third lower mold positioning grooves 114c. The cross-section of these lower mold positioning grooves in the thickness direction of the lower mold plate 11 is a rectangle with rounded corners, and the dimensions are basically the same. The difference lies in their position and the length direction of the groove.

[0041] Two first lower mold positioning grooves 114a are respectively formed on opposite sides of the lower mold insert 112 and are connected to the lower mold insert 112. The first lower mold positioning grooves 114a are arranged parallel to each other, and their length direction is basically consistent with the side length direction of the lower mold insert 112 where they are located, that is, basically consistent with one diagonal direction of the lower template 11.

[0042] Two second lower mold positioning grooves 114b are respectively formed on the other two opposite sides of the lower mold insert 112 and are connected to the lower mold insert 112. The second lower mold positioning grooves 114b are arranged parallel to each other, and their length direction is basically consistent with the side length direction of the lower mold insert 112 where they are located, that is, basically consistent with the other diagonal direction of the lower template 11.

[0043] Four third lower mold positioning grooves 114c are respectively formed on one side of the four sides of the lower mold insert 112. The third lower mold positioning grooves 114c are arranged parallel to each other, and their length direction is consistent with the length direction of the lower template 11.

[0044] In an alternative, the first lower mold positioning groove 114a and the second lower mold positioning groove 114b may not be connected to the lower mold insert groove 112, but may be set separately next to the lower mold insert groove 112.

[0045] Figure 5 This is a perspective view of the lower mold locking block in this embodiment.

[0046] like Figure 5 As shown, the lower mold locking block 12 includes an integrally formed fitting portion 121 and a locking portion 122. The fitting portion 121 is block-shaped and matches the lower mold positioning groove 114, meaning the cross-section of the fitting portion 121 is also rectangular with rounded corners. The locking portion 122 is block-shaped and larger than the fitting portion 121, extending from the lower surface of the locking portion 122 along the height direction of the lower mold locking block 12. The cross-section of the locking portion 122 in the width direction of the lower mold locking block 12 is approximately trapezoidal, such that the locking portion 122 has a side inclined relative to the height direction of the lower mold locking block 12, which is the locking surface 122a. The fitting portion 121 is positioned relatively close to the locking surface 122a.

[0047] The lower mold locking block 12 also has a mounting hole 123 that penetrates the fitting portion 121 and the locking portion 122.

[0048] As shown in Figure 4 each lower mold locking block 12 is mounted at the corresponding lower mold locking block mounting groove 113 by a corresponding fastener (bolt), the fitting portion 121 of each lower mold locking block 12 is fitted in the corresponding groove, the lower surface of the locking portion 122 abuts against the upper surface of the lower mold plate 11, and the locking surface 122a faces the middle portion of the lower mold plate 11.

[0049] In an alternative, the lower mold locking block 12 can also be formed integrally with the lower mold plate 11.

[0050] The upper mold portion 20 has a structure similar to that of the lower mold portion 10, and therefore only a brief description is given below.

[0051] Figure 6 is a perspective view of the upper mold portion in this embodiment.

[0052] As shown in Figure 6 the upper mold portion 20 has an upper mold plate 21 and a plurality of upper mold locking blocks 22.

[0053] The upper mold plate 21 has a through mold core fitting hole 211 formed in the middle portion, a upper mold fitting groove 212 and a plurality of upper mold locking block mounting grooves 213 formed on the surface facing the lower mold portion 10, and a plurality of through upper mold positioning holes 214. The opposite two side surfaces of the upper mold plate 21 each have an upper mold lug hole 215 formed therein.

[0054] The mold core fitting hole 211 is a circular through hole with a diameter smaller than that of the mold core fitting hole 111 of the lower mold portion 10.

[0055] The upper mold fitting groove 212 has a structure basically the same as that of the lower mold fitting groove 112. The upper mold locking block mounting grooves 213 are used to mount the upper mold locking blocks 22, and in this embodiment, there are eight of them. The upper mold locking blocks 22 have a structure basically the same as that of the lower mold locking blocks 12 and also have an inclined locking surface 222a. In the closed mold state, the eight upper mold locking blocks 22 and the eight lower mold locking blocks 12 correspond to each other in the mold opening and closing direction (i.e., the vertical direction in the figure).

[0056] The upper mold positioning holes 214 are strip-shaped through holes that penetrate the thickness direction of the upper mold plate 21 and are distributed around the upper mold fitting groove 212, and are used to cooperate with the corresponding positioning block structure of the mold core portion 30. In this embodiment, there are four of them, which are two first upper mold positioning holes 214a and two second upper mold positioning holes 214b.

[0057] Two first upper die positioning holes 214a are formed at opposite sides of the upper die slot 212 and communicate with the upper die slot 212. The first upper die positioning holes 214a are parallel to each other and their length directions are substantially consistent with the length directions of the side portions of the upper die slot 212.

[0058] Two second upper die positioning holes 214b are formed at opposite other sides of the upper die slot 212 and communicate with the upper die slot 212. The first upper die positioning holes 214a are parallel to each other and their length directions are substantially consistent with the length directions of the side portions of the upper die slot 212.

[0059] Figure 7 is a perspective view of the die core part in the embodiment.

[0060] As shown in Figure 7 , the die core part 30 includes two matched sliders 31, a plurality of upper die positioning blocks 32, a plurality of lower die positioning blocks 33, and a plurality of wear-resistant blocks 34.

[0061] Each slider 31 is in the shape of a C-shaped block, the two ends of the C-shaped block are used to be connected with the two ends of the C-shaped block of another slider 31, the outer side of the C-shaped block is a slider outer side 311, and the inner side of the C-shaped block is a slider forming side 312. The upper and lower end faces of the slider 31 are substantially planar.

[0062] The slider outer side 311 has a circumferential outer side surface, which includes an upper side surface 311a, a middle side surface 311b, and a lower side surface 311c connected in sequence. The middle side surface 311b is parallel to the thickness direction of the slider 31, and the upper side surface 311a and the lower side surface 311c are inclined long strip surfaces relative to the thickness direction, so that the areas of the upper and lower end faces of the slider 31 are smaller than the cross-sectional area of the middle part in the thickness direction of the slider 31. Therefore, from the perspective of the side (i.e. Figure 7 , the middle part of the slider outer side 311 in the thickness direction protrudes, and the upper and lower ends are inclined inward. In the embodiment, the inclination angles of the upper side surface 311a and the lower side surface 311c correspond to the inclination angles of the locking surfaces of the upper die locking block 22 and the lower die locking block 12, respectively.

[0063] A plurality of wear-resistant block mounting grooves 3111 are distributed on the inclined upper side surface 311a and the lower side surface 311c, which are used to mount the wear-resistant blocks 34. The wear-resistant block mounting grooves 3111 are strip-shaped grooves with shallow groove depths, and the groove bottoms have threaded holes. In the embodiment, the cross sections of the wear-resistant block mounting grooves 3111 are rectangular with rounded corners.

[0064] The slider forming side 312 has a plurality of curved and flaky protrusions, the outer end surfaces of the protrusions are forming surfaces 312a, the forming surfaces 312a are arc surfaces, and the plurality of forming surfaces 312a are located on a unified circular surface. In the embodiment, each slider 31 has four forming surfaces 312a with the same size.

[0065] The upper end surface of the slide block 31 is formed with a plurality of upper positioning block mounting grooves 313 corresponding to the plurality of upper die positioning holes 214 for mounting the upper die positioning blocks 32. The lower end surface of the slide block 31 is formed with a plurality of lower positioning block mounting grooves corresponding to the plurality of lower die positioning grooves 114 for mounting the lower die positioning blocks 33.

[0066] In addition, the outer end surface of one end of the slide block 31 is also formed with a strip-shaped glue discharge groove 315. When the two slide blocks 31 are combined, the slide block forming sides 312 of the two slide blocks 31 are combined together, forming a substantially annular cylindrical forming cavity 351 between the upper surface of the lower die plate 11, the two slide blocks 31, the lower surface of the upper die plate 21, and the core portion 40. The glue discharge grooves 315 of the end portions of the slide blocks 31 are combined together to form glue discharge holes 352 communicating with the forming cavities. The middle portion of the slide block 31 in the bending direction is also provided with a plurality of glue overflow holes 316 communicating with the forming cavities 351, one end of each glue overflow hole 316 being located between two adjacent forming surfaces 312a. In this embodiment, there are three glue overflow holes 316. One side of the slide block 31 in the bending direction is also provided with a plurality of air discharge holes 317 communicating with the forming cavities 351, one end of each air discharge hole 317 also being located between two adjacent forming surfaces 312a. The outer side 311 of the slide block is also provided with two recessed air discharge matching grooves 318 communicating with the air discharge holes 317.

[0067] The upper end surface and the outer surface of the slide block 31 are also provided with a plurality of lifting ring holes 319, which are symmetrically distributed along the central axis of the whole formed by the two slide blocks 31, and can be used to mount a plurality of lifting rings.

[0068] The upper die positioning blocks 32 are in the shape of a strip block, the cross-sectional shape in the height direction thereof matches the upper die positioning holes 214, and the middle portion thereof has a mounting hole penetrating in the height direction thereof. Each upper die positioning block 32 is mounted in the corresponding upper positioning block mounting groove 313 by a corresponding fastener (bolt), and the upper end of the upper die positioning block 32 protrudes above the upper end surface of the slide block 31.

[0069] The lower die positioning blocks 33 are also in the shape of a strip block, the cross-sectional shape in the height direction thereof matches the lower die positioning grooves 114, and the middle portion thereof also has a mounting hole penetrating in the height direction thereof. Each lower die positioning block 33 is mounted in the corresponding lower positioning block mounting groove by a corresponding fastener, and the lower end of the lower die positioning block 33 protrudes below the lower end surface of the slide block 31.

[0070] In this embodiment, the structures of all the upper die positioning blocks 32 and the lower die positioning blocks 33 are basically the same, the cross-section in the height direction thereof is in the shape of a rectangle with rounded corners, the same type of component and the same type of fastener can be used, thereby reducing the machining complexity of the mold 100.

[0071] The wear-resistant block 34 is a flat, strip-shaped block. Its cross-sectional shape in the thickness direction matches the wear-resistant block mounting groove 3111, and its thickness is slightly greater than the groove depth. The wear-resistant block 34 has mounting holes at both ends, the positions of which correspond to the threaded holes at the bottom of the groove. Therefore, when the wear-resistant block 34 is installed in the groove, one end in the thickness direction slightly protrudes beyond the inclined surface. In this embodiment, the positions of the multiple wear-resistant blocks 34 installed on the upper side 311a correspond to the positions of the upper mold locking blocks 22, respectively; the positions of the multiple wear-resistant blocks 34 installed on the lower side 311c correspond to the positions of the lower mold locking blocks 12, respectively.

[0072] Figure 8 This is a perspective view of the mold core in this embodiment.

[0073] like Figure 8 As shown, the mold core part 40 includes a mold core base 41 and a mold core body 42 arranged coaxially.

[0074] The mold core base 41 consists of two coaxial disc-shaped parts with different diameters. Its overall structure matches the mold core assembly hole 111 and can be fitted into the hole.

[0075] The mold core body 42 is cylindrical, with a diameter smaller than that of the mold core base 41 and larger than that of the mold core mating hole 211. A lifting ring hole 421 is provided in the middle of its upper end face.

[0076] In this embodiment, the upper template 21, lower template 11, and slider 31 are made of P20 mold steel, while other components are made of 45 steel. The wear-resistant blocks and bolts are commercially available standard parts.

[0077] The overall installation and disassembly of mold 100, as well as mold opening and closing, can be carried out using lifting rings, lifting lugs, etc. When opening the mold, only the upper mold part 20 needs to be lifted up, that is, the mold 100 in this embodiment is a two-stage mold. Then, the two sliders 31 slide away in opposite directions, and the mold core part 40 is lifted up to bring out the processed vibration isolation rubber support, thus achieving demolding.

[0078] Figure 9 This is a perspective view of the vibration isolation rubber bearing mold in use in this embodiment.

[0079] like Figure 9 As shown, in use, the preform 9 is first placed on the lower mold part 10 containing the mold core part 40, so that its square lower base plate 91 is embedded in the lower mold groove 112, and the mold core part 40 passes through the through hole in the middle of the preform 9. Then, the two sliders 31 are closed together to cover the middle section of the preform 9. The upper mold part 20 is then placed above the preform 9, so that its square upper base plate 92 is roughly embedded in the upper mold groove 212.

[0080] Then, when the mold is closed (i.e. the upper mold part 20, the core part 30, and the lower mold part 10 are pressed together along the vertical direction), the upper end of each of the two sliders 31 in the combined state is inserted into the corresponding upper mold positioning hole 214, and the lower end of each of the two sliders 31 is inserted into the corresponding lower mold positioning groove 114, thereby accurately positioning the relative positions of the upper mold part 20, the core part 30, and the lower mold part 10. At the same time, the locking surface 122a of each upper mold locking block 12 abuts against the outer surface of the corresponding wear-resistant block 34 at the upper end edge of the slider 31, and the locking surface 222a of each lower mold locking block 22 abuts against the outer surface of the corresponding wear-resistant block 34 at the lower end edge of the slider 31, thereby locking the two sliders 31 in multiple directions.

[0081] At the same time, as shown in Figure 9 the four upper mold positioning blocks 32 at the upper end of the slider 31 are also used to clamp and position the upper bottom plate 92 of the preform 9, and similarly, four of the lower mold positioning blocks 33 at the lower end of the slider 31 are also used to clamp and position the lower bottom plate 91 of the preform 9, thereby making the position of the preform 9 in the mold 100 more accurate.
