Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1 and 2, a quick opening and closing production device for antique cavel blue bricks comprises a top plate 1, a bottom plate 2, a locking mechanism 3, an upper silica gel mold 4 and a lower silica gel mold 5. Roof 1 with bottom plate 2 is corresponding right angle type structure and shape looks adaptation respectively, and roof 1 with the both ends of bottom plate 2 are all crisscross to be equipped with circular bead 6, roof 1 with form the structure similar with archaize goat's horn blue or green brick external shape after bottom plate 2 sets up relatively from top to bottom. The locking mechanism 3 is disposed on the top plate 1 and the bottom plate 2 and is used for fixing the top plate 1 and the bottom plate 2 at opposite positions. Go up the silicon rubber mold 4 with the silicon rubber mold 5 is fixed respectively roof 1 with the relative one side of bottom plate 2, preferred: as shown in fig. 5-8, the upper silicone mold 4 and the lower silicone mold 5 are respectively attached to one side of the top plate 1 opposite to the bottom plate 2 through glue, and the lower silicone mold 5 is provided with a groove 13 for forming texture lines at corresponding positions on the surface of the antique cavel blue brick. The grooves 13 enable the surfaces of the formed antique goat's horn blue bricks to have certain friction, and guarantee that the goat's horn bricks can be quickly installed on a wall body and cannot fall off. Go up the silica gel mould 4 with lower silica gel mould 5 is in roof 1 with relative from top to bottom and locking fixed back is relative butt enclose into with archaize goat's horn blue brick structure assorted die cavity, through filling cement binding material with the shaping production archaize goat's horn blue brick to the die cavity. The bottom of the bottom plate 2 is provided with three supports 12 for supporting the bottom plate, and the three supports 12 are arranged at the bottom of the bottom plate 2 in a triangular shape. In the forming process, the three supports 12 support the whole device, so that the device is stably placed in a resting mode in production. Slurry supplementing openings communicated with the die cavity are respectively formed in the two ends of the top plate 1 and the bottom plate 2 and the shoulder 6, and end covers 7 for sealing the slurry supplementing openings are arranged at the slurry supplementing openings.
As shown in fig. 3 and 4, two hinge mechanisms 8 for folding or turning the top plate 1 and the bottom plate 2 into a right-angle structure are respectively and uniformly arranged in the middle of the top plate and the bottom plate. Preferably: the hinge mechanism 8 includes a rotary shaft and two cylinders. The middle parts of the top plate 1 and the bottom plate 2 are disconnected to be divided into two parts, two sides of the two cylinders are respectively fixed on one part of the top plate 1 or the bottom plate 2 and correspond to the corresponding positions of the disconnected parts, the middle part of the rotating shaft is fixed on the other part of the top plate 1 or the bottom plate 2 and corresponds to the positions of the cylinders, and two ends of the rotating shaft are respectively positioned in the two cylinders in a damping rotation mode.
The locking mechanisms 3 are arranged in a plurality and are uniformly arranged on the edges of the top plate 1 and the bottom plate 2 in a circle. Preferably: the locking mechanism 3 comprises a hasp and a seat. The hasp is hinged to the edge of the top plate 2 or the edge of the top plate 1 and corresponds to the position of the hasp, and the hasp can be buckled on the hasp after rotation so as to fix the top plate 1 and the bottom plate 2 at opposite positions up and down.
As shown in fig. 9, the end cap 7 includes a first strip 9 and a second strip 10. The width of the first block strip 9 is greater than that of the second block strip 10, the second block strip 10 is fixed in the middle of one side of the first block strip 9 to form a T-shaped structure, the second block strip 10 is located on the outer side of the corresponding slurry supplementing opening, and the first block strip 9 is located inside the corresponding slurry supplementing opening. The both ends of first piece 9 are inclined plane 11, and inclined plane 11 avoids in the production process because the tip of first piece 9 collides with the unexpected phenomenon of emergence, and is convenient for the one hand grip first piece 9 and carries out corresponding operation end cover with carrying out end cover 7: the first block 9 is tightly held by one hand at the grout supplementing opening, the cement cementing material on the inner wall of the grout supplementing opening is cleaned through the second block 10 in a pushing mode, the end part of the claw brick can be leveled by means of the second block 10 (the position corresponding to the grout supplementing opening is the end part of the claw brick), and then the second block 10 of the end cover 7 is plugged into the corresponding grout supplementing opening. The second strips 10 are made of silica gel materials, can be quickly demoulded, and can ensure the sealing performance of a grout filling port, so that the cement cementing materials are prevented from overflowing.
The production process of the device is explained in a complete way as follows:
firstly, the folded top plate 1 and the folded bottom plate 2 are turned into a right-angle structure by means of a hinge mechanism, and then the upper silicon mold 4 and the lower silicon mold 5 are respectively attached and fixed on the top plate 1 and the bottom plate 2 through glue (the upper silicon mold 4 and the lower silicon mold 5 also form a right-angle structure with a horizontal part and a vertical part).
And step two, filling cement gel materials (with low slump) for the goat horn brick on the horizontal part of the lower silicon mold 5, enabling the horizontal part of the upper silicon mold 4 to be close to the horizontal part of the lower silicon mold 5, and quickly fastening the horizontal part by virtue of the locking mechanisms 3 at the two side edges of the top plate 1 and the bottom plate 2 so as to press the horizontal parts of the upper silicon mold 4 and the lower silicon mold 5 (the locking mechanisms 3 corresponding to the vertical parts of the upper silicon mold 4 and the lower silicon mold 5 are not fastened yet).
And step three, turning over the device, namely, exchanging the positions of the horizontal part and the vertical part of the upper silica gel mold 4 and the lower silica gel mold 5, changing the vertical part into the horizontal part, and then filling the cement cementing material on the current horizontal part according to the method in the step two.
And step four, checking the filling condition of the mortar at the two ends of the goat horn brick through the mortar filling port, and performing mortar filling and leveling through the end cover 7.
And step five, the first block strip 9 is tightly held by one hand at the grout filling port, the cement cementing materials on the inner wall of each grout filling port are cleaned through the second block strip 10 in a pushing mode, and the end part of the goat horn brick can be leveled by means of the second block strip 10 again.
Step six, after the slurry supplementing and sealing are completed, the whole device is stably placed at an open position by arranging the support 12 through the bottom plate 21.
And seventhly, after the time that the model of the goat's horn brick can be opened is reached, the locking mechanism 3 is used for opening the top 1 and the bottom plate 2 to carry out rapid mould opening, and the complete antique goat's horn brick can be obtained. By this, one duty cycle ends.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
