Therefore, air can be well exhausted in the press-fit process, and the press-fit forming effect is ensured.

Description

Technical Field

[0001] The utility model relates to the technical field of multilayer board molds, and more specifically, to a multilayer board processing and forming mold. Background Art

[0002] Wood plastic board is a high-tech green and environmentally friendly new decorative material mainly made of wood (wood cellulose, plant cellulose) as the base material with thermoplastic polymer materials (plastics) and processing aids, which are evenly mixed and then heated and extruded by mold equipment. It has the performance and characteristics of both wood and plastic and is a new composite material that can replace wood and plastic.

[0003] The existing multi-layer board pressing device mainly presses the multi-layer boards stacked horizontally and vertically through an oil pump, but the pressing plate currently used is mainly a flat plate structure, so when pressing the bottom multi-layer board, the multi-layer boards will be pressed in the middle and around at the same time. In this way, after the pressing is completed on the four sides, the air in the middle will not be discharged in time, which greatly affects the effect after pressing, and a larger pressing force is required to better discharge the air, which increases the difficulty of the production process. Therefore, it needs to be improved. Utility Model Content

[0026] The extrusion member 3 includes two front and rear extrusion plates 31 connected to the lower end of the linkage component 7, and a limiting slide groove 32 is provided in the middle of the extrusion plate 31, and the lower end of the linkage component 7 is slidably connected to the inside of the limiting slide groove 32; the proximal ends of the two extrusion plates 31 are movably sleeved with a connecting rod 34, and the two ends of the connecting rod 34 pass through the extrusion plate 31 and are fixedly connected with a first connecting block 35, and the two extrusion plates 31 are connected to the first connecting block 35 through the connecting rod 34; due to the setting of the extrusion plate 31, the proximal ends of the two extrusion plates 31 can be made lower than the distal ends thereof under the cooperation of the connecting rod 34 and the first connecting block 35, and then when the linkage component 7 pushes the extrusion plate 31 to move downward, the contact surface between the bottom of the two extrusion plates 31 and the multilayer board can be in a state of spreading from the middle to the surroundings, thereby facilitating the good exhaust of air during the pressing process and ensuring the pressing and forming effect.

[0027] Among them, the linkage assembly 7 includes two left and right support rods 72 movably connected to the bottom of the connecting seat 6, and a plurality of limit rods 73 are fixedly connected inside the support rod 72. A limit rod 73 located at the bottom is slidably connected to the inside of the limit slide groove 32. The inside of the limit slide groove 32 is movably sleeved with a plurality of limit bearings 33, and the limit bearings 33 are fixedly sleeved on the outside of the limit rod 73.

[0028] Among them, two front and rear reset components 74 are arranged above the extrusion plate 31, and the two ends of the reset component 74 are movably connected with the second connecting block 75, and the bottom of the reset component 74 is fixedly connected with a number of evenly distributed adapting pressure blocks 76, the bottom of the second connecting block 75 is fixedly connected to the extrusion plate 31, and the bottom of the adapting pressure block 76 is in contact with the top of the extrusion plate 31; due to the setting of the adapting pressure block 76, with the cooperation of the second connecting block 75, the reset component 74 can remain parallel to the two extrusion plates 31 when it moves down to the lowest point, so that the driving force of the support rod 72 can be more evenly applied to the two extrusion plates 31 through the reset component 74, the second connecting block 75 and the adapting pressure block 76, so that the two extrusion plates 31 can finally cover the multi-layer board in a horizontal state to ensure the final pressing flatness.

[0029] The distances between the lower end of the second connecting block 75 and the lower end of the adapting pressing block 76 and the bottom of the reset assembly 74 are the same.

[0030] The reset assembly 74 includes two left and right movable limit rods 741 . A limit sliding cavity 742 is provided inside the movable limit rod 741 . A positioning sliding rod 744 is movably sleeved between the two movable limit rods 741 .

The outer diameter dimension of the limiting slide block 743 is larger than the outer diameter dimension of the positioning slide bar 744, and the outer diameter dimension of the limiting slide block 743 is adapted to the inner diameter dimension of the limiting slide cavity 742. Due to the setting of the limiting slide block 743, the relative movement of the positioning slide bar 744 and the two movable limiting rods 741 can be limited with the cooperation of the limiting slide cavity 742. While ensuring that the two movable limiting rods 741 follow the movement of the extrusion plate 31, it is ensured that the two movable limiting rods 741 will not separate from each other and become independent, and that the two movable limiting rods 741 can be reset when rising.

[0033] A support frame 4 is provided at the bottom of the operating platform 1 , and the operating platform 1 is installed on the top of the support frame 4 by bolts.

[0034] The working principle and use process of this utility model:

[0035] The multilayer boards placed on the top of the operating table 1 are stacked in sequence just below the extrusion member 3, and the equipment is turned on so that the lower end of the hydraulic rod 5 pushes the hinge 71 downward through the connecting seat 6. The movement of the hinge 71 can push the two support rods 72 downward, and then the left and right extrusion plates 31 are slowly moved downward under the cooperation of the limiting slide groove 32, the limiting bearing 33 and the limiting rod 73, and the adjacent ends of the two extrusion plates 31 are first contacted with the lower multilayer board under the restriction of the connecting rod 34, the first connecting block 35 and the reset assembly 74; when the adjacent ends of the two extrusion plates 31 are in contact with the multilayer board, the two extrusion plates 31 are in contact with the multilayer board. When the layer boards are against each other, due to the continuous downward movement of the hinge 71, the support rod 72 can push the outer ends of the extrusion plates 31 at both ends gradually close to the lower multi-layer board through the limiting rod 73 with the cooperation of the limiting slide groove 32 and the limiting bearing 33, so that the contact surface between the bottom of the extrusion member 3 and the top of the lower multi-layer board gradually spreads from the middle to the surrounding areas, until finally, under the restriction of the reset component 74 and the obstruction of the bottom multi-layer board, the two extrusion plates 31 can reach a completely horizontal state with the cooperation of the second connecting block 75 and the adapter pressing block 76, and the pressing and forming of the multi-layer board is completed.
