Description

Technical Field

[0001] This utility model belongs to the field of foaming mold technology, and in particular relates to a foaming mold with adjustable foam thickness. Background Technology

[0002] Foaming molds are tools used for plastic foaming molding. By filling foaming resin into the mold and heating it to melt it into a gas-liquid saturated solution, microbubbles are generated through nucleation and grow to form foam plastic parts. The molding methods include physical foaming, chemical foaming and mechanical foaming. Among them, structural foaming molding belongs to the chemical method and can produce dense, integral foamed materials.

[0003] Most existing molds only have the function of forming. After the foaming material is piled up in the mold, uneven distribution at the edges is likely to occur, which will affect the foam's incomplete expansion in the mold and thus affect the quality of the foam. When conducting foaming experiments, it is necessary to select a suitable mold according to the specific foam thickness. However, most current foaming molds can only complete the foaming of fixed-size foam. For different foam thickness requirements, different molds must be used, which is cumbersome and reduces the ease of use of the molds.

[0004] Therefore, this invention provides a foaming mold with adjustable foam thickness to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0039] In specific implementation, such as Figures 1-6As shown, this utility model provides a technical solution: a foaming mold with adjustable foam thickness, including a box body 1.

[0040] Both the rotating rod 301 and the support rod 302 are fixedly mounted with toothed sprockets 303. The toothed sprockets 303 are connected by a toothed chain drive. The toothed sprockets 303 and the toothed chain are located inside the lifting box 505. Both the rotating rod 301 and the support rod 302 are fixedly mounted with cylindrical cams 305.

[0041] The shaking mechanism 3 also includes a shaking plate 304, which is located above the lifting box 505. Several fixing rods 3010 are fixedly installed on the lower surface of the shaking plate 304. The fixing rods 3010 are distributed at the four corners of the shaking plate 304, and one end of the fixing rods 3010 extends into the interior of the lifting box 505.

[0042] A fixing plate 309 is fixedly installed at one end of the fixing rod 3010. A connecting spring 308 is fixedly installed on the upper surface of the fixing plate 309. The connecting spring 308 is sleeved on the outside of the fixing rod 3010, and one end of the connecting spring 308 is fixedly connected to the inner wall of the top surface of the lifting box 505.

[0043] A connecting rod 306 is symmetrically fixedly installed on the lower surface of the shaking plate 304. One end of the connecting rod 306 extends into the interior of the lifting box 505. A pulley 307 is rotatably installed on the side wall of the connecting rod 306 via a rotating shaft. The pulley 307 and the cylindrical cam 305 are mutually adapted to each other.

[0044] The sliding mechanism 4 includes a movable rod 401, a fixed plate 406, a sliding groove 408, and a sealing plate 409. Support springs 402 are fixedly installed at both ends of the movable rod 401. Several sliding rods 403 are fixedly installed at equal intervals on the upper surface of the movable rod 401.

[0045] The slide groove 408 is set on the upper surface of the vibrating plate 304. The lower surface of the sealing plate 409 is fixedly connected to the upper surface of the vibrating plate 304. The sealing plate 409 is located above both ends of the sealing groove. The inner wall of the slide groove 408 is slidably connected to the outer surface of the movable rod 401. One end of the support spring 402 is fixedly connected to the inner side wall of the slide groove 408. The support spring 402 is located below the sealing plate 409. The upper surface of the fixed plate 406 is fixedly connected to the inner wall of the top surface of the lifting box 505. A top block 407 is fixedly installed on the side wall of the fixed plate 406. The top block 407 and the protrusion 405 are mutually adapted. Both the top block 407 and the protrusion 405 are set as equilateral trapezoids.

[0046] Specifically, by setting up the shaking mechanism 3 and the sliding mechanism 4, the rotating rod 301 rotates inside the lifting box 505. With the cooperation of the toothed sprocket 303 and the toothed chain, the support rod 302 also drives the lifting box 505 to rotate. At this time, the cylindrical cam 305 on the outer surface of the rotating rod 301 and the support rod 302 will rotate synchronously. As the cylindrical cam 305 rotates, under the action of the pulley 307, the connecting rod 306 drives the shaking plate 304 to shake up and down above the lifting box 505 under the limit of the fixed rod 3010 and the connecting spring 308. At this time, the shaking plate 304 will drive the foaming material to shake synchronously. When the shaking plate 304 shakes up and down... The movable rod 401 is moved synchronously, which in turn moves the mounting plate 404 and the protrusion 405 synchronously. Under the action of the fixed plate 406 and the top block 407, the mounting plate 404 moves the movable rod 401 back and forth in the slide groove 408 under the limit of the support spring 402. As the movable rod 401 moves back and forth, it drives the sliding rod 403 to move synchronously back and forth. The sliding rod 403 pulls the foaming material, reduces the air in the foaming material by shaking, and ensures the density of the foaming material. The sliding also makes the foaming material evenly dispersed in the box 1, avoiding the situation of insufficient foaming of the foaming material in the box 1.

[0047] The adjustment mechanism 5 also includes a limiting plate 501. The lower surface of the limiting plate 501 is rotatably connected to the inner wall of the bottom surface of the housing 1. A threaded rod 502 is fixedly installed on the upper surface of the limiting plate 501. One end of the threaded rod 502 extends into the cavity of the lifting box 505. The outer surface of the threaded rod 502 is threadedly connected to the inner wall of the shell cavity at the bottom of the lifting box 505. A rotating column 503 is fixedly installed on the lower surface of the limiting plate 501. A rotating rod 504 is slidably installed through the inner wall of the rotating column 503.

[0048] Specifically, by setting the adjustment mechanism 5, the rotating rod 504 drives the rotating column 503 to rotate within the box 1 under the limit of the limiting plate 501. At this time, the limiting plate 501 will drive the threaded rod 502 to rotate synchronously. As the threaded rod 502 rotates, the lifting box 505 will move up and down within the box 1 under the action of the thread. By moving the lifting box 505, the volume of the box 1 is changed, so that the box 1 can be used for foaming of different thicknesses. During the movement of the lifting box 505, the shaking mechanism 3 and the sliding mechanism 4 will be moved synchronously.

[0049] Working principle: Based on the required foam thickness, the volume of the box 1 is adjusted by changing the height of the lifting box 505 within the box 1 in the adjusting mechanism 5, so that the lifting box 505 is adjusted to an appropriate position. Then, the foaming material is injected into the box 1. At this time, the shaking mechanism 3 is activated, causing the shaking plate 304 to shake the foaming material. While the shaking mechanism 3 is working, it also drives the sliding mechanism 4 to work synchronously. At this time, the sliding rod 403 in the sliding mechanism 4 will pull the foaming material back and forth. With the cooperation of the vibration generated by the shaking, the foaming material is evenly dispersed in the box 1, ensuring the foaming quality.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
