Detailed Description

The invention is described in detail below with reference to the figures and examples.

Example (b):

the preparation process of the prefabricated interior wallboard comprises the following steps,

first, people will use an injection molding and demolding production line.

Wherein, as shown in fig. 1-4, the injection molding demolding production line comprises a lifting platform 4, a bedplate 5 fixedly connected to the movable end of the lifting platform 4, a mold movably arranged above the bedplate 5, and a stirring machine 2 arranged above the mold, wherein the stirring machine 2 is fixed by a support frame 1, the top surface of the mold is communicated with a rotary pipe joint 7, the stirring machine 2 is communicated with a conveying pipeline 3, the conveying pipeline 3 is used for being communicated with the rotary pipe joint 7, one end outer ring of the conveying pipeline 3, far away from the stirring machine 2, is fixedly connected with a flange plate 6, the conveying pipeline 3 is detachably connected with the rotary pipe joint 7 by the flange plate 6, the flange plate 6 and the rotary pipe joint 7 are padded with a sealing ring, and the two are connected by bolts and nuts.

5 top surface fixedly connected with circular orbit 12 of platen, two straight track 13 of fixedly connected with and circular orbit 12 intercommunication on the platen 5, two straight track 13 syntropy and parallel arrangement, the bottom surface fixedly connected with roll connection of mould is universal wheel 11 in circular orbit 12, be provided with on the platen 5 and be used for driving mould pivoted driving piece, the driving piece can be dismantled with the mould and be connected, the driving piece includes servo motor 14 of fixed connection in 5 bottom surfaces of platen and runs through platen 5 and with servo motor 14 output shaft coaxial fixed connection's telescopic link 15, the upper end of telescopic link 15 is the polygon, the recess with 15 gomphosis of telescopic link is seted up to the bottom surface of mould.

The mould includes the lower bolster 10 of mutual detachable connection from bottom to top in proper order, frame 9 and cope match-plate pattern 8, lower bolster 10, also connect through bolt and nut between frame 9 and the cope match-plate pattern 8, the recess is seted up on the bottom surface of lower bolster 10, set up on the cope match-plate pattern 8 with the coaxial through-hole that sets up of rotary pipe joint 7,

rotary pipe joint

7 and 8 fixed connection of cope match-plate pattern, universal wheel 11 also is through the fix with screw on lower bolster 10 bottom surfaces.

Concrete mixing is performed by a mixer 2 in the injection molding and demolding production line, and materials are prepared in advance.

Accomplish the framework of steel reinforcement and build in the mould in the line is produced in the drawing of patterns of moulding plastics, the volume of mould is less than the volume of concrete, and the framework of steel reinforcement builds the in-process in the mould, and stirring machine 2 carries out the stirring of concrete in step, can improve work efficiency, carries out two works in step.

4 with the mould lifting through the elevating platform in the drawing of patterns of moulding plastics production line, make 2 delivery pipe of discharge gate department of mixer 3 and the rotatory coupling 7 intercommunication on the mould, set up both clearance seals when delivery pipe 3 communicates with

rotatory coupling

7, 4 drive platens 5 of elevating platform this moment rise, then after ring flange 6 aligns the laminating with rotatory coupling 7, both extrusion seal circle, and people are through artificial mode, utilize bolt and nut, be connected ring flange 6 and rotatory coupling 7, guarantee sealed effect and joint strength between the two, make the difficult condition that breaks away from in both.

Make the mould take place the circumference and rotate on elevating platform 4, people pass through manual mode pulling telescopic link 15 this moment, make its extension, make it insert in the recess, because the part of embedding is the polygon, so when making servo motor 14 drive telescopic link 15 pivoted, can drive the mould and take place the rotation together, and the mould passes through universal wheel 11 and rolls in circular orbit 12, cooperation telescopic link 15 is to the support of mould, make the difficult condition that takes place to rock of mould at the rotation in-process, and is more stable.

The concrete that passes through in 2 blenders 2 passes through pipeline 3 and the leading-in mould of swivel coupling 7, the concrete is after entering into the mould, because the mould takes place to rotate, under the effect of centrifugal force, the concrete is got rid of to the outer lane, thereby make the concrete can be in the mould, from the inside edge of mould beginning to fill, and keep the condition that the concrete compressed tightly, get rid of the bubble in the concrete, avoid the concrete in the mould to appear a bubble, and because the volume of mould is less than the volume of concrete, so make after filling, the inside of mould can be filled completely to the concrete.

After concrete pouring is finished, the mold is stopped, people contact the connection between the bolts and the nuts, and the mold is displaced downwards through the lifting platform 4, so that the flange plate 6 is separated from the rotary pipe joint 7, and the downward displacement of the mold is not limited.

Demolish the mould, through hardware and tools and artificial mode, dismantle cope match-plate pattern 8, the concrete is in not yet solidifying but has plastic state this moment, the condition that can not take place to collapse.

After standing and treating the concrete solidification to the unnecessary concrete is eradicated, thereby make people can obtain the prefabricated interior wallboard that dimensional specification accords with people's requirement, and the production of wallboard is comparatively convenient in this prefabrication, can accomplish production through one set of production line, demolishs comparatively conveniently to the template simultaneously.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
