Abstract

The present invention relates to a movable mould which comprises an upper mould plate (1) connected with a first cylinder (11), and an inner mould (3) connected with a fixed mould plate (2). A charging guide plate (4) is positioned on the inner mould (3). One side wall of the inner mould (3) and the fixed mould plate (2) have corresponding row holes (5). The inner mould (3) presents a concave shape, with both ends opened. Both side walls of the inner mould (3) are connected with the first fixed mould plate (2) and a first movable mould plate (6). A second fixed mould plate (7) and the first fixed mould plate (2) are fixedly connected with a pressing machine (8). A second movable mould plate (9), the first movable mould plate (6) and the inner mould (3) are orderly arranged between the second fixed mould plate (7) and the first fixed mould plate (2). Two bevels of the wedge-shaped second movable mould plate (9) are respectively matched with one side wall of the second fixed mould plate (7) and one side wall of the first movable mould plate (6).

Description

Flexible mould

Technical field:

The present invention is relevant with the pressure forming apparatus of bamboo or wood composite profile, and is especially relevant with the strengthened bamboo material mould.

Background technology:

Existing strengthened bamboo material moulding mould special, by hydraulic press, upper die and lower die, internal mold, internal mold eject pump and reinforced guide plate is formed, and several locked mode pins are housed on the internal mold, and counterdie is the integral rigidity mould, and sidewall has several locked mode conduits.During work, the mao bamboon raw material is placed in the reinforced guide plate of internal mold both sides, the primer fluid press, patrix is pressed into internal mold with the mao bamboon raw material and makes its moulding, get some locked mode pins again and head into internal mold by the locked mode conduit, with the solid type of the bamboo wood of the type of being pressed into, make the press release again, start delivery eject pump with the shaped bamboo material that suppresses together with internal mold from bottom to top integral body eject the disengaging counterdie, and concentrate to enter to solidify in the baking oven and handle moulding, take out the locked mode pin then, unload core insert, finish the production process that bamboo wood is strengthened moulding.Because counterdie is an integral body, its inner chamber is connected with internal mold, and bamboo wood makes internal mold and counterdie closely cooperate in internal mold behind high-pressure molding, and need eject pump could eject it from counterdie, depanning cost height, and power consumption is big, and fragile mould and shaped bamboo material.The locked mode pin enters internal mold and directly contacts with bamboo wood and must brute force head into, and catheter directed owing to only having at counterdie, entering the internal mold side does not have guide pipe, operation inconvenience, and the locked mode pin is difficult for entering in the hole of another sidewall of internal mold, can not effectively make the solid type of bamboo wood of the type of being pressed into.After internal mold is ejected counterdie,, be easy to make the internal mold distortion, influence internal mold service life and bamboo wood quality because of the expansion of bamboo wood in the heat cure operation owing to have only the solid shape of row's locked mode pin.

Summary of the invention:

The purpose of this invention is to provide a kind of simple in structure, long service life, with low cost, easy to operate, the demoulding is easy, and is energy-conservation Gu type is effective, product quality height, the flexible mould that production efficiency is high.

The present invention is achieved in that

Flexible mould of the present invention, comprise the cope match-plate pattern 1 that is connected with first oil cylinder 11, the internal mold 3 that is connected with first fixed form 2, reinforced guide plate 4 is positioned on the internal mold 3, one sidewall of internal mold 3 has corresponding round 5 with first fixed form 2, internal mold 3 is the spill of both ends open, its two side is connected with first collapsible form 6 with first fixed form 2 respectively, second fixed form 7 and first fixed form 2 are connected with press 8, place second collapsible form 9 therebetween successively, first collapsible form 6, internal mold 3, two inclined-planes of wedge shape second collapsible form 9 cooperate with a side of second fixed form 7 and first collapsible form 6 respectively.

One sidewall porose 5 of internal mold 3 is corresponding with blind hole or blind groove on first collapsible form 6.

The hole that second collapsible form 9 passes on the platform of press 8 is connected with second oil cylinder 10.

Hole 5 on internal mold 3 two sides is two row of horizontal holes.

There is parallel groove 13 lower surface of cope match-plate pattern 1, and the two-port of groove 13 is corresponding with the hole 5 of the two side of internal mold 3 respectively, has cover plate 12 to be connected with the lower surface of cope match-plate pattern 1 and closed pockets 13.

Internal mold of the present invention is positioned at fixed form, be fixed on the press platform by collapsible form, can bear very big pressure, during the demoulding, need only unload collapsible form with artificial or oil cylinder, because collapsible form is a wedge shape, taking-up power is little, directly internal mold is not exerted a force, can not influence the quality of internal mold life-span and bamboo wood yet.Because screw rod directly contact with bamboo wood at internal mold but enters another sidewall of internal mold through the pilot hole of patrix and cover plate formation, must brute force not head into, Gu type is reliable,, arrange fixedly section bar of screw rods by two owing to internal mold has two rounds, can not be out of shape during heat treatment.Cover plate is pushed down section bar can make its resilience not in curing time, and can make product size precision and surface smoothness height.The present invention is simple in structure, and low cost of manufacture is easy to operate, long service life, and it is low to consume energy, the product quality height.The production efficiency height.

The specific embodiment:

Press 8 is fixedlyed connected with first and second fixed

form

2,7, sets gradually second collapsible form, 9, the first collapsible forms 6 on the platform of the press 8 between first and second fixed

form

2,7, internal mold 3.The hole that second collapsible form 9 passes platform is connected with oil cylinder 10, its wedge shape two inclined-planes cooperate with the side of second fixed form 7 and first collapsible form 6 respectively, internal mold 3 is a flute profile, its two perpendicular wall has corresponding level two rounds 5, the groove of corresponding first collapsible form 6 of following round 5 difference and the hole of first fixed form 2, the reinforced guide plate 4 of the top organic frame supporting of internal mold 3.During work, raw material such as bamboo or wood enters internal mold 3 through reinforced guide plate, the cope match-plate pattern 1 that is connected with oil cylinder 11 by cover plate 12 exert pressure downwards with raw material molded after, with screw rod 14 from first fixed form 2 the hole and the passage that forms of the hole 5 on the sidewall of internal mold 3 and the groove by cover plate 12 and cope match-plate pattern 1 lower surface enter internal mold 3 another sidewall on hole 5 and the groove of first collapsible form 6.Cope match-plate pattern 1 is promoted, by oil cylinder 10 second collapsible form 9 is moved downward and withdraw from the press platform, first collapsible form 6 breaks away to its spatial translation withdrawed from and internal mold 3, can take out the internal mold of plate with cover and typing raw material, at this moment, pass internal mold and screw on nut fastening from the last round 5 of internal mold 3 screw rod 14.Internal mold 3 gone into take out screw rod 14 after shaping raw material is sent into heating stone or metal plate for standing a stove on as a precaution against fire curing molding, because internal mold is to adopt spring steel plate to make, the raw material of curing molding is taken out in the internal mold resilience.
