A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0023] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0024] See also Figures 1 to 4 As shown, this preferred embodiment provides a large-tonnage rubber and plastic foaming machine, including a machine base 1, on which a supporting column 2 is arranged. In this embodiment, eight supporting columns 2 are arranged, and a top cover 3 is installed on the supporting column 2. A plurality of hot plate components 4 stacked up and down are arranged between the machine base 1 and the top cover 3, and the hot plate components 4 are used to provide the temperature required for foaming. Foaming materials are placed between adjacent hot plate components 4. A pressurizing component 5 is arranged on the machine base 1, and the pressurizing component 5 is used to drive each hot plate component 4 to press each other.
[0025] In particular, a feed rack and a discharge rack are respectively provided at both ends of each hot plate component 4 in the feed and discharge direction, and brackets 6 are respectively provided on both sides of each hot plate component 4 in the feed and discharge direction. During the foaming process, parts of the foaming material overflowing from the hot plate component 4 are respectively received by the feed rack, the discharge rack and the bracket 6, and the overflowed part remains on the feed rack, the discharge rack and / or the bracket 6, or the overflowed part is output to the discharge rack along with the formed foaming material.
[0026] The feed rack and the discharging rack here are normal loading and unloading conveying mechanisms and will not be further described. Generally speaking, the overflowing part will adhere to the formed foaming material and flow to the discharging rack along with the formed foaming material, and the personnel can remove the overflowing part on the discharging rack; some overflowing parts may remain on the feed rack, the discharging rack and the bracket 6, and can be cleaned up by the personnel in time.
[0027] Therefore, in order to solve the problem of foaming material overflowing from the mold during hot pressing, the large-tonnage rubber and plastic foaming machine is designed with a bracket 6 and cooperates with a feed rack and a discharge rack to receive the overflowing material, so as to prevent the overflowing material from freely flowing down along the mold surface, thereby solving the problem of troublesome cleaning, and the received overflowing material is more convenient for personnel to clean up, and will not affect the subsequent foaming. In addition, the large-tonnage rubber and plastic foaming machine has an ultra-wide format, with a width of up to 3600mm.
[0028] Optionally, the bracket 6 is fixed to the side surface of the hot plate component 4 by bolts, and the bracket 6 extends along the upper surface of the hot plate component 4 and tilts downward by 5° to 10°. This tilt angle allows the overflowing material to slide to both sides of the hot plate component 4, so as to centrally clean up the overflowing material and reduce the workload of personnel for timely cleaning. In addition, the bracket 6 is a split structure to avoid interference with the support column 2.
[0029] Furthermore, a heat insulating block is provided between the bracket 6 and the hot plate component 4 to prevent heat from being conducted to the bracket 6 , reduce heat loss, and prevent people from accidentally touching the bracket 6 and getting burned.
[0030] In particular, adjacent hot plate components 4 are connected by a cross-link assembly 7, so that each hot plate component 4 rises or falls synchronously, and the spacing between each hot plate component 4 remains consistent, so that each hot plate component 4 can open and close the mold at the same time, fully utilizing the equipment space and improving the foaming efficiency.
[0031] Furthermore, the pressurizing component 5 comprises a hydraulic cylinder, the output end of which faces upward and is fixedly connected to the lowest hot plate component 4 , so that the driving force for mold closing and pressure maintaining is provided by the hydraulic cylinder.
[0032] Furthermore, a slide plate 8 is provided on the supporting column 2, and the hot plate component 4 moves up and down along the slide plate 8. A step block 9 is provided on the slide plate 8. Each step surface of the step block 9 is used to limit the downward stroke of each hot plate component 4 one by one, thereby ensuring that the movement stroke of each hot plate component 4 is consistent.
[0033] In particular, a diverter 10 is provided on the supporting column 2, a fluid medium containing heat is provided in the diverter 10, and a plurality of taps 11 are provided on the diverter 10. Each tap 11 is connected to the corresponding hot plate component 4 through a pipeline to provide the same heat energy to each hot plate component 4 to ensure consistent foaming effect everywhere.
[0034] In addition, the top cover 3 is divided into several parts, and each part is provided with a lifting lug 12. In view of the difficulty in assembling a large-tonnage rubber and plastic foaming machine, the top cover 3 is designed to be split, which is more conducive to crane lifting and assembly, and will not affect the function of the foaming machine.
[0035] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
