Description

Secondary die assembly auxiliary mechanism, die trolley and production line

Technical Field

The invention relates to the technical field of light plates or bricks, in particular to an auxiliary mechanism for secondary die assembly, a die car and a production line thereof, which are arranged on the die car of a light plate or brick production line.

Background

On the production line of light plate material and light brick material several open-close moulds are mounted on the mould car side by side. When the mould car reaches the demoulding station, the mould on the mould car needs to be opened, and after the light plate material and brick material products in the mould are unloaded, the bottom plate, the front side plate, the rear side plate and the top plate of the open-close mould need to be replaced and the mould is closed.

In the existing one-time mold closing process, the mold is closed from the front and rear outermost molds of the mold, and the next mold is closed after the mold is closed, so that when the side plates and the top plate are placed, workers cannot effectively place (tilt and topple) the side plates and the top plate due to the large distance between the adjacent partition plates after opening the mold, and therefore, when the mold is closed, the workers need to repeatedly adjust the postures of the side plates and the top plate to smoothly close the mold, and more time is wasted.

Accordingly, there is a need in the art for further improvements and perfection.

Another object of the present invention is to overcome the deficiencies of the prior art and to provide a molding machine using the above mechanism.

The third object of the present invention is to overcome the shortcomings of the prior art and provide a production line using the above-mentioned mold vehicle.

The aim of the invention is achieved by the following technical scheme:

the secondary mould closing auxiliary mechanism mainly comprises a connecting plate for limiting the distance between adjacent partition plates in the first mould closing process, a driving mechanism for supporting the connecting plate, and a first pressing block and a second pressing block for gradually pressing a top plate and a side plate in the second mould closing process.

Specifically, a plurality of connecting plates are vertically arranged at the left side and the right side of the mould car and mainly comprise connecting parts for connecting adjacent partition plates and clamping parts for clamping the bottom plate. The clamping part is arranged above the connecting part and is fixedly connected with the connecting plate. And special-shaped connecting grooves are symmetrically formed in two ends of the connecting part. The special-shaped connecting groove penetrates through the connecting plate and comprises a first connecting groove which is horizontally arranged and a second connecting groove which is vertically arranged. The second connecting groove is obliquely arranged on one side, close to the middle of the connecting plate. The first connecting groove is communicated with the second connecting groove. The clamping part is internally provided with a clamping groove for clamping the column bottom plate. The end part of the bottom plate is clamped in the clamping groove. The width of the clamping groove is slightly larger than that of the bottom plate.

Further, the connecting plate further comprises a bolt for connecting the partition plate. One end of the bolt is vertically inserted into the special-shaped connecting groove and is fixedly connected with the partition plate, and the size of the end head of the other end of the bolt is larger than the widest part of the special-shaped connecting groove.

As a preferable scheme of the invention, the outer surface of the bolt and the inner surface of the special-shaped connecting groove are both provided with a hardness enhancing layer.

Further, a convex strip is arranged on one side, close to the middle of the connecting plate, of the second connecting groove. The convex strips and the connecting plates are integrally formed. The cross section of each raised line is trapezoidal, the bottom of each raised line is fixedly connected with the connecting plate, and the top area of each raised line is smaller than the bottom area.

As a preferable mode of the invention, the end parts of the first connecting groove and the second connecting groove are arc structures.

As a preferable scheme of the invention, the transverse width of the bottommost part of the second connecting groove is larger than the diameter of the bolt.

As a preferred embodiment of the present invention, the first connecting groove has a lateral width greater than that of the second connecting groove. The innermost distance between the two first connecting grooves in the same connecting plate is smaller than the width of the bottom plate.

Specifically, the driving mechanism is arranged below the connecting plate and drives the connecting plate to move upwards or downwards. The driving mechanism further comprises a supporting plate, an air cylinder and a linear guide rail. The supporting plates are respectively arranged at the left side and the right side of the die trolley and are positioned below the connecting plates. The linear guide rails are vertically arranged on the left side and the right side of the supporting plate respectively and are connected with the supporting plate. The cylinder is arranged below the supporting plate, the output end of the cylinder is connected with the bottom of the supporting plate, and the supporting plate is driven to upwards support the connecting plate.

Specifically, the first compaction blocks are arranged at the top of the partition plate and are positioned at two sides of the top plate. The second compaction blocks are arranged on the left side and the right side of the partition plate and are positioned on the two sides of the side plate. The first compression block and the second compression block adopt the same structure and mainly comprise a mounting seat, a first compression part arranged on the front side of the mounting seat and a second compression part symmetrically arranged with the first compression part. The first pressing part and the second pressing part adopt the same structure and mainly comprise a pressing section and a holding section. The pressing section is positioned at the upper part of one side close to the center of the die, and the holding section is positioned at the lower part. When the die is assembled, the compression section of the compression part is contacted with the top plate or the side plate at first, the compression section of the first compression block on the two partition plates can gradually compress the top plate downwards along with the gradual reduction of the distance between the two adjacent partition plates, and the compression section of the second compression block can also gradually compress the side plate inwards. With the continuous decrease of the distance between the adjacent partition boards, the contact position between the top plate and the first compression block or the contact position between the side plate and the second compression block enters the holding section from the compression section. Until the die is completely closed, the top plate or the side plate can completely enter the limit range of the retaining section, so that the top plate and the side plate are kept to be tightly pressed between the adjacent partition plates.

As a preferable scheme of the invention, the cross-section outline of the pressing section is one or a combination of a plurality of straight lines, a plurality of sections of lines and an arc line which are obliquely arranged. The function of the compacting section is twofold: on the one hand, the top plate or the side plate is guided into the holding section, so that the inclination degree or the slope of the pressing section is not too large; and on the other hand, the device is used for preliminarily clamping the top plate or the side plate, so that the top plate or the side plate can maintain the effective clamping posture. The cross-sectional profile of the retaining segment is a straight line that is horizontal. The holding section is used for maintaining the pressure on the top plate and the side plates in the curing and forming stage after grouting so as to keep the pressure in the die constant after grouting.

Furthermore, in order to facilitate placement of the top plate and the side plate, the top of the mounting seat is also provided with a groove for placing the top plate or the side plate. When the die is opened, a worker only needs to place the disassembled top plate in the groove on the first compression block adjacent to the top of the partition plate, and the side plate is placed in the groove on the second compression block on the side surface of the same partition plate, so that the operation is simple, convenient and quick.

As a preferred embodiment of the present invention, in order to facilitate the placement of the top plate or floor into the recess, the upper edge of the recess is provided to be inclined inwardly.

Further, in order to stably place the side plate on the side surface of the partition plate, the secondary mold clamping auxiliary mechanism further comprises a supporting plate for supporting the side plate. The bearing plate is arranged on the left side and the right side of the partition plate and positioned below the second compression block, and comprises a supporting part and a positioning part. The locating part is arranged at the top end of the supporting part and protrudes upwards. Preferably, the protrusions are arranged at two positions side by side and at intervals at the top end of the supporting part. During operation, the worker only needs to detach the side plates, and inserts the lower ends (hollow-out parts) of the side plates at two convex positions to finish the placing operation.

Another object of the invention can be achieved by the following technical scheme:

the die trolley is provided with the secondary die closing auxiliary mechanism. The auxiliary mechanism can enable the opening and closing die on the die car to realize secondary die closing operation.

The third object of the present invention can be achieved by the following technical scheme:

a light board production line is provided with a plurality of mould cars. The mould car continuously circularly manufactures light boards or bricks on a production line, and the mould car is provided with the secondary mould closing auxiliary mechanism.

The working process and principle of the invention are as follows:

when in installation, the connecting plate is positioned between the adjacent partition plates and is connected with the partition plates through bolts. The plurality of first compaction blocks are arranged at the top of the partition board and are arranged side by side at intervals. The second compaction blocks are arranged on the left side surface and the right side surface of the partition board and are arranged side by side at intervals. And the bearing plates are arranged on the left side surface and the right side surface of the partition plate and are positioned below the second compression block.

Before die assembly, each die on the die trolley is in a maximum die opening state, the distance between adjacent partition plates is maximum, and the bolt is positioned at the outermost end of the first connecting groove. The bottom plate is placed between adjacent baffles, and the tip card of bottom plate is established in the draw-in groove of connecting plate.

Starting to mold the first time, the cylinder acts first to push the supporting plate upwards, and the supporting plate is contacted with the bottoms of all connecting plates on the same side after a certain distance is lifted and continuously pushes the connecting plates upwards. At this time, the latch moves downward relative to the connection plate, and enters the lowermost end of the second connection groove from the first connection groove. The outermost partition board is pushed first, and the bolt represents the position of the partition board, and the movable range of the bolt is limited by the groove width of the second connecting groove on the connecting board, so that under the condition that the connecting board is supported, the outermost partition board and the adjacent partition board can only be clamped for a certain distance (the distance is determined by the inner side distance between the two second connecting grooves on the connecting board), after the first clamping of the outermost mold is completed, the outermost partition board is pushed continuously, the adjacent partition board is pushed by the connecting board, and the like, so that the first clamping operation of the rest mold is completed.

After the first die assembly of all the dies on the die truck is completed, the worker takes the top plate off the groove of the first compression block and places the top plate at the top position of the adjacent partition plate, and the top plate is clamped and limited by the first compression blocks at two sides. And meanwhile, the side plates positioned on the bearing plates (protruding and double limiting of the grooves) are taken down and placed at the left side surface and the right side surface of the adjacent partition plates, and are clamped and limited by the second compression blocks at the two sides. After the top plate and the side plates are loaded, the second mold closing is started, the cylinder acts first, the supporting plate and all the connecting plates are carried down, and the bolts move upwards relative to the connecting plates. The bolt at this time enters the first connecting groove from the second connecting groove. Then, the separator which is still at the outermost side is pushed, and the width of the first connecting groove is wider than that of the second connecting groove, so that the bolt can move towards the middle part of the connecting plate under the pushing of external force, namely, the distance between the adjacent separators can be further reduced. In the process, the top plate is guided and pressurized by the first compression block, the side plate is guided and pressurized by the second compression block, contacts with the adjacent partition plate and the bottom plate, compresses and forms a closed cavity for grouting, and the second mold closing is completed.

In the process of opening and closing the die, the clamping grooves are always clamped at the two ends of the bottom plate, and the difference is that when the connecting plate is lifted, the depth of the bottom plate entering the clamping grooves is deeper, and after the connecting plate is put down, the depth of the bottom plate entering the clamping grooves is shallower. Therefore, the bottom plate is controlled by the connecting plate and is kept at the middle part of the adjacent partition plates, and the design has the advantages that the connecting plate brings the bottom plate and products to be separated from the adjacent partition plates in demolding during mold opening, and the bottom plate can be kept at the middle part of the adjacent partition plates at the moment during mold closing, so that two purposes are achieved.

Compared with the prior art, the invention has the following advantages:

(1) The connecting plate provided by the invention adopts a special-shaped connecting groove design, and the distance between adjacent partition plates can be limited, so that a worker can conveniently place the side plates and the top plate at corresponding positions, the time spent by repeated placement of the worker and intervention and adjustment of an auxiliary mechanism is saved, and the production efficiency is improved.

(2) According to the connecting plate provided by the invention, the trapezoid raised strips are added on the inner side of the second connecting groove, so that the contact area between the bolt and the second connecting groove can be reduced, and the connecting plate can descend along with the supporting plate under the action of self gravity when the supporting plate descends, and the condition that the connecting plate is blocked and clamped with the bolt is avoided.

(3) The connecting plate provided by the invention is provided with the clamping groove for clamping the bottom plate so as to control the position of the bottom plate at any time, thereby being beneficial to demolding of products on one hand, and on the other hand, the bottom plate can be kept at a central position at any time, and the initial semi-finished product is prevented from being mutually lost due to collision or friction with the partition plate during demolding.

(4) The first compression block and the second compression block provided by the invention can guide and compress the top plate and the side plate on one hand so as to maintain the constant pressure in the die, and can initially position the top plate and the side plate on the other hand, so that a worker can maintain an effective posture when placing the top plate and the side plate and guide and adjust the top plate and the side plate to a proper position along with die closing.

(5) The supporting plate provided by the invention can effectively position and support the side plates, so that the side plates detached by workers can be easily and conveniently placed aside during die opening, and the side plates are not randomly placed.

(6) Because different products need to use the connecting plates with different specifications, the set of supporting plate device provided by the invention can be matched with the connecting plates with different specifications for use, can reduce investment cost and is convenient to operate.

The clamping part 2 is arranged above the connecting part 1 and is fixedly connected with the connecting plate 13. The two ends of the connecting part 1 are symmetrically provided with special-shaped connecting grooves 3. The special-shaped connecting groove 3 penetrates through the connecting plate 13 and comprises a first connecting groove 4 horizontally arranged and a second connecting groove 5 vertically arranged. The second connecting groove 5 is obliquely arranged on one side close to the middle of the connecting plate 13. The first connecting groove 4 is communicated with the second connecting groove 5. The clamping part 2 is internally provided with a clamping groove 6 for clamping a column bottom plate 25. The end of the bottom plate 25 is clamped in the clamping groove 6. The slot width of the clamping slot 6 is slightly larger than the width of the bottom plate 25.

Further, the connecting plate 13 further comprises a latch 7 for connecting the partition 12. One end of the bolt 7 is vertically inserted into the special-shaped connecting groove 3 and fixedly connected with the partition plate 12, and the size of the end head of the other end is larger than the widest part of the special-shaped connecting groove 3.

As a preferable scheme of the invention, the outer surface of the bolt 7 and the inner surface of the special-shaped connecting groove 3 are both provided with a hardness enhancing layer.

Further, a convex strip 8 is arranged on one side of the second connecting groove 5 close to the middle of the connecting plate 13. The raised strips 8 and the connecting plate 13 are integrally formed. The cross section of each raised line 8 is trapezoidal, the bottom of each raised line 8 is fixedly connected with the connecting plate 13, and the top area of each raised line is smaller than the bottom area.

As a preferable mode of the present invention, the ends of the first connecting groove 4 and the second connecting groove 5 have a circular arc structure.

As a preferable mode of the present invention, the lateral width of the bottommost part of the second connecting groove 5 is larger than the diameter of the bolt 7.

As a preferred embodiment of the present invention, the lateral width of the first connecting groove 4 is greater than the lateral width of the second connecting groove 5. The innermost distance between two of said first connecting grooves 4 in the same connecting plate 13 is smaller than the width of the bottom plate 25.

Specifically, the driving mechanism is disposed below the connection plate 13, and drives the connection plate 13 to move upward or downward. The driving mechanism further comprises a supporting plate 9, an air cylinder 10 and a linear guide rail 11. The supporting plates 9 are respectively arranged at the left side and the right side of the mould carriage 28 and are positioned below the connecting plate 13. The linear guide rails 11 are vertically arranged on the left side and the right side of the supporting plate 9 respectively and are connected with the supporting plate 9. The cylinder 10 is arranged below the supporting plate 9, the output end of the cylinder is connected with the bottom of the supporting plate 9, and the supporting plate 9 is driven to lift the connecting plate 13 upwards.

As shown in fig. 10 to 16, in particular, the first pressing block 14 is mounted on top of the partition 12 and located on both sides of the top plate 26. The second pressing blocks 15 are installed on the left and right sides of the partition plate 12 and located on both sides of the side plate 27. The first compression block 14 and the second compression block 15 have the same structure, and mainly comprise a mounting seat 16, a first compression part 17 arranged on the front side of the mounting seat 16, and a second compression part 18 symmetrically arranged with the first compression part 17. The first pressing part 17 and the second pressing part 18 have the same structure, and mainly comprise a pressing section 19 and a holding section 20. The hold-down section 19 is located at the upper part of the side close to the centre of the mould and the holding section 20 is located at the lower part. During die assembly, the pressing section 19 of the pressing part is contacted with the top plate 26 or the side plate 27 first, and as the distance between the two adjacent partition plates 12 is gradually reduced, the pressing section 19 of the first pressing block 14 on the two partition plates 12 gradually presses down the top plate 26, and the pressing section 19 of the second pressing block 15 also gradually presses down the side plate 27 inwards. As the distance between adjacent spacers 12 becomes smaller, the contact position of the top plate 26 with the first pressing block 14 or the side plate 27 with the second pressing block 15 is entered from the pressing section 19 to the holding section 20. Until the clamping is completed, the top plate 26 or the side plate 27 is completely brought into the limit range of the holding section 20, thereby holding both the top plate 26 and the side plate 27 pressed between the adjacent partition plates 12.

As a preferred embodiment of the present invention, the cross-sectional profile of the pressing section 19 is one or more of a straight line, a multi-sectional line, and an arc line that are obliquely arranged. The function of the compacting section 19 is twofold: on the one hand, the top plate 26 or the side plate 27 is guided into the holding section 20, so that the degree of inclination or the slope of the pressing section 19 is not to be too great; on the other hand, the clamping device is used for preliminarily clamping the top plate 26 or the side plate 27, so that the top plate 26 or the side plate 27 maintains the effective clamping posture. The cross-sectional profile of the retaining segment 20 is a straight line that is horizontal. The function of the retaining section 20 is to maintain the pressure on the top plate 26 and the side plates 27 during the post-grouting curing forming stage to keep the pressure in the post-grouting mold constant.

Further, in order to facilitate placement of the top plate 26 and the side plate 27, the top of the mounting seat 16 of the present invention is further provided with a groove 21 for placing the top plate 26 or the side plate 27. When the die is opened, a worker only needs to place the disassembled top plate 26 in the groove 21 on the first pressing block 14 adjacent to the top of the partition plate 12, and the side plate 27 is placed in the groove 21 on the second pressing block 15 on the side surface of the same partition plate 12, so that the operation is simple, convenient and quick.

As a preferred embodiment of the present invention, in order to facilitate the placement of the top plate 26 or the floor into the recess 21, the upper edge of the recess 21 is provided to be inclined inwardly.

Further, in order to stably place the side plate 27 on the side of the partition plate 12, the secondary mold clamping auxiliary mechanism of the present invention further includes a support plate 22 for supporting the side plate 27. The bearing plates 22 are arranged on the left side and the right side of the partition plate 12 and positioned below the second compression block 15, and comprise a supporting part 23 and a positioning part 24. The positioning portion 24 is provided at the top end of the supporting portion 23 and protrudes upward. Preferably, the protrusions are provided in two places, side by side and spaced apart at the top of the support 23. During operation, a worker only needs to detach the side plate 27, and insert the lower end (hollow) of the side plate 27 at two convex positions to finish the placing operation.

Another object of the invention can be achieved by the following technical scheme:

the secondary mold clamping auxiliary mechanism is arranged on the mold carriage 28. By this auxiliary mechanism, the opening and closing mold on the mold carriage 28 can be subjected to the secondary mold closing operation.

The third object of the present invention can be achieved by the following technical scheme:

a lightweight board production line is provided with a number of mould carriages 28. The mould carriage 28 continuously circularly manufactures light plates or bricks on a production line, and the mould carriage 28 is provided with the secondary mould closing auxiliary mechanism.

The working process and principle of the invention are as follows:

when in installation, the connecting plates 13 are positioned between the adjacent partition plates 12, and are connected with the partition plates 12 through the bolts 7. A plurality of first hold-down blocks 14 are mounted on top of the separator 12, side by side and spaced apart. A plurality of second compaction blocks 15 are arranged on the left side surface and the right side surface of the partition plate 12 side by side and at intervals. And the bearing plates 22 are installed on the left and right sides of the partition plate 12 below the second pressing block 15.

Before clamping, each die on the die carriage 28 is in the maximum die opening state, the distance between the adjacent partition plates 12 is maximum, and the bolt 7 is positioned at the outermost end of the first connecting groove 4. The bottom plate 25 is placed between the adjacent partition plates 12, and the end of the bottom plate 25 is clamped in the clamping groove 6 of the connecting plate 13.

The first mold closing is started, the cylinder 10 is firstly operated to push the supporting plate 9 upwards, and after the supporting plate 9 is lifted for a certain distance, the supporting plate is contacted with the bottoms of all the connecting plates 13 on the same side and the connecting plates 13 are continuously pushed upwards. At this time, the latch 7 moves downward with respect to the connection plate 13, and enters the lowermost end of the second connection groove 5 from the first connection groove 4. The outermost partition plate 12 is pushed first, and since the bolt 7 represents the position of the partition plate 12, the movable range of the bolt 7 is limited by the groove width of the second connecting groove 5 on the connecting plate 13, so that the outermost partition plate 12 and the adjacent partition plate 12 can be clamped only by a distance (the distance is determined by the inner distance between the two second connecting grooves 5 on the connecting plate 13) when the connecting plate 13 is lifted, the outermost partition plate 12 continues to be pushed after the first clamping operation of the outermost mold is completed, and the adjacent partition plate 12 is pushed by the connecting plate 13, and so on, so that the first clamping operation of the remaining mold is completed.

After the first mold closing of all the molds on the mold truck 28 is completed, the worker removes the top plate 26 from the groove 21 of the first pressing block 14 and places it on the top of the adjacent partition 12, and the first pressing blocks 14 on both sides clamp and limit it. And meanwhile, the side plates 27 positioned on the supporting plate 22 (with double limiting of the convex and concave grooves 21) are taken down and placed at the left and right side surfaces of the adjacent partition plates 12, and are blocked and limited by the second compression blocks 15 at the two sides. After the top plate 26 and the side plates 27 are loaded, the second mold closing is started, the cylinder 10 is first actuated, with the pallet 9 and all the connection plates 13 moving downwards, and the pins 7 moving upwards with respect to the connection plates 13. The plug pin 7 at this time enters the first connecting groove 4 from the second connecting groove 5. Then, the separator 12, which is still the outermost side, is pushed, and since the width of the first connecting groove 4 is wider than that of the second connecting groove 5, the plug pin 7 can continue to move toward the middle of the connecting plate 13 by the external force, i.e., the distance between the adjacent separators 12 can be further reduced. In this process, the top plate 26 is guided and pressed by the first pressing block 14, and the side plate 27 is guided and pressed by the second pressing block 15, and contacts and presses the adjacent partition plate 12 and the bottom plate 25 to form a closed cavity for grouting, so that the second mold closing is completed.

In the process of opening and closing the mold, the clamping grooves 6 always clamp the two ends of the bottom plate 25, and the difference is that when the connecting plate 13 is lifted, the depth of the bottom plate 25 entering the clamping grooves 6 is deeper, and after the connecting plate 13 is put down, the depth of the bottom plate 25 entering the clamping grooves 6 is shallower. Therefore, the bottom plate 25 is controlled by the connecting plate 13 and is kept at the middle position of the adjacent partition plate 12, and the design has the advantages that the connecting plate 13 brings the bottom plate 25 and products to be separated from the adjacent partition plate 12 in demolding during mold opening, and the bottom plate 25 can be kept at the middle position of the adjacent partition plate 12 in mold closing, so that two purposes are achieved.

The above examples are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above examples, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principle of the present invention should be made in the equivalent manner, and the embodiments are included in the protection scope of the present invention.
