Embodiment Construction
[0022] The present invention is described in detail below in conjunction with embodiment and with reference to accompanying drawing: see Figure 1-7 , the general mold for wood and bamboo curved panels with multi-plunger oil cylinders, including frame, upper mold, lower mold and hydraulic mechanism, from top to bottom there are hanging beam 4, upper beam 2, lifter 3, bearing block 13. Multi-plunger cylinder 5, upper formwork 7, lower formwork 8, base 10, each side has a side plate 14, and the inner walls of the two side plates are relatively equipped with slideways 16 for multi-plunger cylinders, upper formwork slideways 17, The crosspiece 9, the lifter is respectively connected to the suspension beam and the multi-plunger cylinder up and down, and each plunger rod of the multi-plunger cylinder is covered with a return spring. The upper section of the plunger rod 6 is cylindrical, the lower section is narrow and flat, and the lower end is The shape of a round cake matches th...

Abstract
The invention discloses a wood-bamboo curved plate common mold having a multi-plunger oil cylinder. A lifting beam (14), an upper beam (2), a lifter (3), a multi-plunger cylinder (5), an upper template (7), a lower template (8), a base (10), a frame (1) and side plates (14) are arranged in sequence from top to bottom; slide ways (16) of the multi-plunger cylinder, upper template slide ways (17) and cross bars (9) are correspondingly mounted on the inner walls of the two side plates; the upper template is detachably connected with the multi-plunger cylinder through a plunger rod (6); and the lower template is positioned on the upper curved edge of a curved surface shaping plate (15). A curved plate is pressed by the common mold by the following four steps: (1) the common mold is purchased, manufactured and assembled according to design requirements; (2) a thin cushion plate is purchased and used; (3) the pressing is performed; and (4) the mold replacement is performed. The common mold is adopted to manufacture the curved plate, has the advantages of strong universality, low technical difficulty, low cost and convenient and fast mold replacement, and only needs to manufacture two curved shaping plates with the same shape and size.
Description
technical field [0001] The invention relates to a wood and bamboo board processing equipment and method, in particular to a general mold and a pressing method for pressing wood and bamboo artificial curved boards. Background technique [0002] When wood and bamboo wood-based panels are used to produce furniture, it is often necessary to press flat panels into curved panels. According to different requirements of shape design, the curvature and shape of curved panels are different, and sometimes need to be changed. For example, the shape and size of the seat board, support board and back board of the chair are different, the ones used by adults are different from those used by children, and the ones used by households and public places are different. For a long time, it has been pressed by upper and lower molds that match the shape and size one by one. One pair of molds presses a curved panel with a fixed shape and size. If you change a curved panel with a different shape or...
