Description

Technical Field

[0001] The present invention relates to the technical field of lightweight panels or bricks, and in particular to an auxiliary mechanism for secondary mold closing installed on a mold vehicle of a lightweight panel or brick production line, the mold vehicle and the production line thereof. Background Art

[0002] On the production line for lightweight sheet metal and lightweight bricks, multiple split molds are mounted side by side on a mold cart. When the mold cart arrives at the demolding station, the mold on the cart needs to be opened. After unloading the lightweight sheet metal and brick products from the mold, the bottom plate, front and rear side plates, and top plate of the split mold need to be returned to their original positions and the mold closed.

[0003] The existing one-time mold closing process starts from the outermost molds in the front and rear of the mold car, and the next mold is closed only after the outermost mold is closed. Therefore, when placing the side panels and top panels, the distance between adjacent partitions is large after the mold is opened, which makes it difficult for workers to place them effectively (they are tilted or tilted). Therefore, when closing the mold, workers need to repeatedly adjust the posture of each side panel and top panel to successfully close the mold, which wastes a lot of time.

[0004] Therefore, the existing technology needs to be further improved and perfected. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an auxiliary mechanism for secondary mold closing.

[0006] Another object of the present invention is to overcome the deficiencies of the prior art and provide a mold vehicle using the above-mentioned mechanism.

[0007] The third object of the present invention is to overcome the deficiencies of the prior art and provide a production line using the above-mentioned mold vehicle.

[0008] The purpose of the present invention is achieved through the following technical solutions:

[0009] A secondary mold closing auxiliary mechanism mainly includes a connecting plate for limiting the distance between adjacent partitions during the first mold closing, a driving mechanism for supporting the connecting plate, and a first pressing block for gradually pressing the top plate and a second pressing block for pressing the side plates during the second mold closing.

[0010] Specifically, several connecting plates are vertically installed on the left and right sides of the mold vehicle, mainly including a connecting portion for connecting adjacent partitions, and a clamping portion for clamping the bottom plate. The clamping portion is arranged above the connecting portion and is fixedly connected to the connecting plate. Special-shaped connecting grooves are symmetrically provided at both ends of the connecting portion. The special-shaped connecting grooves pass through the connecting plate, including a first connecting groove arranged horizontally and a second connecting groove arranged vertically. The second connecting groove is inclined near one side of the middle of the connecting plate. The first connecting groove is connected to the second connecting groove. A clamping groove for clamping the column bottom plate is provided in the clamping portion. The end of the bottom plate is clamped in the clamping groove. The width of the clamping groove is slightly larger than the width of the bottom plate.

[0011] Furthermore, the connecting plate further comprises a latch for connecting the partition, one end of the latch being vertically inserted into the special-shaped connecting groove and fixedly connected to the partition, and the other end having a tip dimension larger than the widest part of the special-shaped connecting groove.

[0012] As a preferred solution of the present invention, the outer surface of the latch and the inner surface of the special-shaped connecting groove are both provided with a hardness-enhancing layer.

[0013] Furthermore, a ridge is provided on one side of the second connection groove near the middle of the connection plate. The ridge is integrally formed with the connection plate. The cross-section of the ridge is trapezoidal, the bottom of the ridge is fixedly connected to the connection plate, and the top area is smaller than the bottom area.

[0014] As a preferred solution of the present invention, the ends of the first connecting groove and the second connecting groove are arc structures.

[0015] As a preferred solution of the present invention, the transverse width of the bottom of the second connecting groove is greater than the diameter of the latch.

[0016] As a preferred solution of the present invention, the transverse width of the first connecting groove is greater than the transverse width of the second connecting groove. The innermost distance between two first connecting grooves in the same connecting plate is less than the width of the bottom plate.

[0017] Specifically, the drive mechanism is positioned below the connecting plate, driving the connecting plate upward or downward. The drive mechanism also includes a support plate, a cylinder, and a linear guide. The support plates are positioned on the left and right sides of the mold vehicle, respectively, below the connecting plate. The linear guides are vertically positioned on the left and right sides of the support plates and connected to the support plates. The cylinder is positioned below the support plate, with its output end connected to the bottom of the support plate, driving the support plate to lift the connecting plate upward.

[0018] Specifically, the first pressing block is installed on the top of the partition, located on both sides of the top plate. The second pressing block is installed on the left and right sides of the partition, located on both sides of the side plate. The first pressing block and the second pressing block adopt the same structure, mainly including a mounting seat, a first pressing portion arranged on the front side of the mounting seat, and a second pressing portion arranged symmetrically with the first pressing portion. The first pressing portion and the second pressing portion adopt the same structure, mainly including a pressing section and a holding section. The pressing section is located at the upper part of the side close to the center of the mold, and the holding section is located at the lower part. When the mold is closed, the pressing section of the pressing section first contacts the top plate or the side plate. As the distance between the two adjacent partitions gradually decreases, the pressing section of the first pressing block on the two partitions will gradually press the top plate downward, and the pressing section of the second pressing block will gradually press the side plate inward. As the distance between the adjacent partitions continues to decrease, the contact position between the top plate and the first pressing block or the side plate and the second pressing block moves from the pressing section to the holding section. After the mold is completely closed, the top plate or the side plate will completely enter the restricted range of the holding section, thereby keeping the top plate and the side plate pressed tightly between the adjacent partitions.

[0019] As a preferred embodiment of the present invention, the cross-sectional profile of the clamping section is a combination of one or more inclined straight lines, multi-segment lines, and arcs. The clamping section has two functions: on the one hand, it guides the top plate or side plate into the holding section, so the degree of inclination or slope of the clamping section should not be too large; on the other hand, it is used to initially clamp the top plate or side plate so that the top plate or side plate maintains an effective mold closing posture. The cross-sectional profile of the holding section is a horizontal straight line. The function of the holding section is to maintain pressure on the top plate and side plates during the curing and forming stage of the lightweight plate after grouting, so as to keep the pressure in the mold constant after grouting.

[0020] Furthermore, to facilitate placement of the top and side panels, the mounting base of the present invention is provided with a groove for receiving the top or side panels. During mold opening, workers simply place the disassembled top panel into the groove of the first pressing block adjacent to the top of the partition, while the side panels are placed into the groove of the second pressing block on the side of the same partition. This makes the operation simple, convenient, and quick.

[0021] As a preferred solution of the present invention, in order to facilitate placing the top plate or floor into the groove, the upper edge of the groove of the present invention is set to be inclined inward.

[0022] Furthermore, in order to stably place the side panels on the sides of the partition, the secondary mold clamping auxiliary mechanism of the present invention also includes a support plate for holding the side panels. The support plate is installed on the left and right sides of the partition, located below the second clamping block, and includes a support portion and a positioning portion. The positioning portion is provided at the top of the support portion and protrudes upward. Preferably, the protrusion is provided in two places, which are arranged side by side and at intervals at the top of the support portion. During operation, the worker only needs to remove the side panel and insert the lower end (hollowed out) of the side panel into the two protruding positions to complete the placement operation.

[0023] Another object of the present invention can be achieved by the following technical solutions:

[0024] A mold car is provided with the secondary mold closing auxiliary mechanism. The auxiliary mechanism can realize the secondary mold closing operation of the opening and closing mold on the mold car.

[0025] The third object of the present invention can be achieved by the following technical solutions:

[0026] A lightweight plate production line is provided with a plurality of mold carriages which continuously circulate on the production line to produce lightweight plates or bricks, and the mold carriages are provided with the secondary mold-closing auxiliary mechanism.

[0027] The working process and principle of the present invention are:

[0028] During installation, the connecting plate is located between adjacent partitions and connected to the partitions via latches. Several first compression blocks are installed on top of the partitions, spaced side by side. Several second compression blocks are installed on the left and right sides of the partitions, spaced side by side. Support plates are installed on the left and right sides of the partitions, below the second compression blocks.

[0029] Before closing the mold, each mold on the mold carriage is in the maximum mold opening state, with the spacing between adjacent partitions at its maximum and the latch located at the outermost end of the first connecting groove. The bottom plate is placed between adjacent partitions, with the end of the bottom plate locked in the slot of the connecting plate.

[0030] At the start of the first mold closing, the cylinder first moves, pushing the support plate upward. After rising a certain distance, the support plate contacts the bottom of all the connecting plates on the same side and continues to push the connecting plates upward. At this time, the latch moves downward relative to the connecting plates, entering the lowest end of the second connecting groove from the first connecting groove. The outermost partition is pushed first. Since the latch represents the position of the partition, and the range of the latch is limited by the width of the second connecting groove on the connecting plate, when the connecting plate is held up, the outermost partition and the adjacent partition can only be closed for a certain distance (this distance is determined by the inner distance between the two second connecting grooves on the connecting plate). After the first mold closing of the outermost mold is completed, the outermost partition continues to be pushed and pushes the adjacent partition through the connecting plate, and so on, thereby completing the first mold closing operation of the remaining molds.

[0031] After the first mold closing of all the molds on the mold cart is completed, the worker removes the top plate from the groove of the first clamping block and places it on the top position of the adjacent partition, which is clamped and limited by the first clamping blocks on both sides. At the same time, the side plates on the support plate (double-limited by protrusions and grooves) are also removed and placed on the left and right sides of the adjacent partition, which are clamped and limited by the second clamping blocks on both sides. After the top plate and side plates are loaded, the second mold closing begins. The cylinder moves first, moving the support plate and all connecting plates downward, while the latch moves upward relative to the connecting plate. At this time, the latch enters the first connecting groove from the second connecting groove. Then, the outermost partition is still pushed. Since the width of the first connecting groove is wider than the second connecting groove, the latch can continue to move toward the middle of the connecting plate under the push of external force, that is, the distance between adjacent partitions can be further reduced. During this process, the top plate is guided and pressurized by the first pressing block, and the side plate is guided and pressurized by the second pressing block, contacting and pressing the adjacent partition plates and bottom plates to form a closed cavity for grouting. At this point, the second mold closing is completed.

[0032] During the mold opening and closing process, the slots constantly engage the ends of the base plate. The difference is that when the connecting plate is lifted, the base plate enters the slots deeper, while when it is lowered, the depth of the slots is shallower. Therefore, the base plate is constantly controlled by the connecting plate and maintained in the middle of the adjacent partitions. The advantage of this design is that during mold opening, the connecting plate carries the base plate and the product away from the adjacent partitions, while during mold closing, it can keep the base plate in the middle of the adjacent partitions, achieving two goals at once.

[0033] Compared with the prior art, the present invention also has the following advantages:

[0034] (1) The connecting plate provided by the present invention adopts a special-shaped connecting groove design, which can limit the distance between adjacent partitions during the first mold closing, thereby making it convenient for workers to place the side panels and top panels in the corresponding positions, saving the workers' time spent on repeated placement, intervention and adjustment by auxiliary mechanisms, and improving production efficiency.

[0035] (2) The connecting plate provided by the present invention has a trapezoidal ridge added on the inner side of the second connecting groove, which can reduce the contact area between the latch and the second connecting groove, thereby ensuring that when the support plate descends, the connecting plate can descend with the support plate under the action of its own gravity, avoiding the occurrence of the connecting plate and the latch being stuck or tightened.

[0036] (3) The connecting plate provided by the present invention is provided with a slot for clamping the bottom plate so as to control the position of the bottom plate at all times. On the one hand, it is beneficial for demoulding the product, and on the other hand, it can keep the bottom plate in the center position at all times, thereby preventing the initial semi-finished product from colliding or rubbing with the partition plate during demoulding and causing loss of each other.

[0037] (4) The first pressing block and the second pressing block provided by the present invention can, on the one hand, guide and press the top plate and the side plate to maintain a constant pressure in the mold, and on the other hand, can preliminarily position the top plate and the side plate so that workers can maintain an effective posture when placing the top plate and the side plate, and guide and adjust them to the appropriate position as the mold is closed.

[0038] (5) The support plate provided by the present invention can effectively position and support the side panels, so that when the mold is opened, the side panels removed by the workers can be easily and conveniently placed aside without being piled up randomly.

[0039] (6) Since different products require connecting plates of different specifications, the set of support plate devices provided by the present invention can be used in conjunction with connecting plates of different specifications, which can reduce investment costs and facilitate operation.

DETAILED DESCRIPTION

[0060] In order to make the objectives, technical solutions and advantages of the present invention more clear and explicit, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0061] Example 1:

[0062] Opening and closing mold: With the forward direction of the mold cart 28 as the front, the opening and closing mold is a detachable mold composed of a bottom plate 25, a top plate 26, left and right side plates 27, and front and rear partitions 12. The front and rear partitions 12 are installed side by side on the mold cart 28. The distance between the front and rear partitions 12 increases with mold opening and decreases with mold closing. The bottom plate 25, top plate 26 and left and right side plates 27 can all be removed separately to cooperate with the mold opening and closing operations.

[0063] like Figures 1 to 9As shown, this embodiment discloses a secondary mold closing auxiliary mechanism, which mainly includes a connecting plate 13 for limiting the distance between adjacent partitions 12 during the first mold closing, a driving mechanism for supporting the connecting plate 13, and a first clamping block 14 for gradually clamping the top plate 26 and a second clamping block 15 for clamping the side plate 27 during the second mold closing.

[0064] Specifically, several connecting plates 13 are vertically installed on the left and right sides of the mold car 28, mainly including a connecting part 1 for connecting adjacent partitions 12, and a clamping part 2 for clamping the bottom plate 25. The clamping part 2 is arranged above the connecting part 1 and is fixedly connected to the connecting plate 13. Special-shaped connecting grooves 3 are symmetrically provided at both ends of the connecting part 1. The special-shaped connecting grooves 3 pass through the connecting plate 13, including a first connecting groove 4 arranged horizontally, and a second connecting groove 5 arranged vertically. The second connecting groove 5 is inclined near one side of the middle of the connecting plate 13. The first connecting groove 4 is connected to the second connecting groove 5. A clamping groove 6 for clamping the column bottom plate 25 is provided in the clamping part 2. The end of the bottom plate 25 is clamped in the clamping groove 6. The width of the clamping groove 6 is slightly larger than the width of the bottom plate 25.

[0065] Furthermore, the connecting plate 13 further comprises a latch 7 for connecting the partition 12. One end of the latch 7 is vertically inserted into the special-shaped connecting groove 3 and fixedly connected to the partition 12, and the other end is larger than the widest part of the special-shaped connecting groove 3.

[0066] As a preferred solution of the present invention, both the outer surface of the latch 7 and the inner surface of the special-shaped connecting groove 3 are provided with a hardness-enhancing layer.

[0067] Furthermore, a ridge 8 is provided on one side of the second connecting groove 5 near the middle of the connecting plate 13. The ridge 8 is integrally formed with the connecting plate 13. The cross-section of the ridge 8 is trapezoidal, and the bottom of the ridge 8 is fixedly connected to the connecting plate 13, with the top area being smaller than the bottom area.

[0068] As a preferred solution of the present invention, the ends of the first connecting groove 4 and the second connecting groove 5 are arc structures.

[0069] As a preferred solution of the present invention, the transverse width of the bottom of the second connecting groove 5 is greater than the diameter of the latch 7 .

[0070] As a preferred embodiment of the present invention, the transverse width of the first connecting groove 4 is greater than the transverse width of the second connecting groove 5. The innermost distance between two first connecting grooves 4 in the same connecting plate 13 is less than the width of the bottom plate 25.

[0071] Specifically, the drive mechanism is disposed below the connecting plate 13, driving the connecting plate 13 upward or downward. The drive mechanism also includes a support plate 9, a cylinder 10, and a linear guide 11. The support plates 9 are disposed on the left and right sides of the mold vehicle 28, respectively, below the connecting plate 13. The linear guides 11 are vertically disposed on the left and right sides of the support plate 9 and connected to the support plate 9. The cylinder 10 is disposed below the support plate 9, with its output end connected to the bottom of the support plate 9, driving the support plate 9 to lift the connecting plate 13 upward.

[0072] Combine Figures 10 to 16 As shown, specifically, the first pressing block 14 is installed on the top of the partition 12, located on both sides of the top plate 26. The second pressing block 15 is installed on the left and right sides of the partition 12, located on both sides of the side plate 27. The first pressing block 14 and the second pressing block 15 adopt the same structure, mainly including a mounting seat 16, a first pressing portion 17 arranged on the front side of the mounting seat 16, and a second pressing portion 18 symmetrically arranged with the first pressing portion 17. The first pressing portion 17 and the second pressing portion 18 adopt the same structure, mainly including a pressing section 19 and a retaining section 20. The pressing section 19 is located at the upper part of the side close to the center of the mold, and the retaining section 20 is located at the lower part. During mold closing, the pressing section 19 of the pressing unit first contacts the top plate 26 or side plate 27. As the distance between adjacent partitions 12 gradually decreases, the pressing section 19 of the first pressing block 14 on each partition 12 gradually presses the top plate 26 downward, while the pressing section 19 of the second pressing block 15 gradually presses the side plate 27 inward. As the distance between adjacent partitions 12 decreases, the contact point between the top plate 26 and the first pressing block 14, or between the side plate 27 and the second pressing block 15, moves from the pressing section 19 to the retaining section 20. Once the mold is fully closed, the top plate 26 or side plate 27 fully enters the restricted range of the retaining section 20, thereby keeping both the top plate 26 and side plate 27 compressed between adjacent partitions 12.

[0073] As a preferred embodiment of the present invention, the cross-sectional profile of the clamping section 19 is a combination of one or more inclined straight lines, multi-segment lines, and arcs. The clamping section 19 has two functions: on the one hand, it guides the top plate 26 or the side plate 27 into the holding section 20, so the degree of inclination or slope of the clamping section 19 should not be too large; on the other hand, it is used to initially clamp the top plate 26 or the side plate 27 so that the top plate 26 or the side plate 27 maintains an effective mold closing posture. The cross-sectional profile of the holding section 20 is a horizontal straight line. The function of the holding section 20 is to maintain pressure on the top plate 26 and the side plate 27 during the curing and forming stage after grouting of the lightweight plate material, so as to keep the pressure in the mold constant after grouting.

[0074] Furthermore, to facilitate placement of the top plate 26 and side plates 27, the top of the mounting base 16 of the present invention is further provided with a groove 21 for receiving the top plate 26 or the side plates 27. During mold opening, workers simply place the disassembled top plate 26 into the groove 21 of the first pressing block 14 adjacent to the top of the partition 12, and the side plates 27 into the groove 21 of the second pressing block 15 on the side of the same partition 12. This operation is simple, convenient, and quick.

[0075] As a preferred solution of the present invention, in order to facilitate placing the top plate 26 or the floor into the groove 21, the upper edge of the groove 21 of the present invention is set to be inclined inward.

[0076] Furthermore, in order to stably place the side panel 27 on the side of the partition 12, the secondary mold clamping auxiliary mechanism of the present invention also includes a support plate 22 for supporting the side panel 27. The support plate 22 is installed on the left and right sides of the partition 12, located below the second clamping block 15, and includes a support portion 23 and a positioning portion 24. The positioning portion 24 is arranged at the top of the support portion 23 and protrudes upward. Preferably, the protrusion is set at two places, which are arranged side by side and at intervals at the top of the support portion 23. During operation, the worker only needs to remove the side panel 27 and insert the lower end (hollow) of the side panel 27 into the two protruding positions to complete the placement operation.

[0077] Another object of the present invention can be achieved by the following technical solutions:

[0078] A mold car, wherein the mold car 28 is provided with the secondary mold clamping auxiliary mechanism. Through the auxiliary mechanism, the opening and closing molds on the mold car 28 can realize the secondary mold clamping operation.

[0079] The third object of the present invention can be achieved by the following technical solutions:

[0080] A lightweight plate production line is provided with a plurality of mold carts 28. The mold carts 28 continuously circulate on the production line to produce lightweight plates or bricks, and the mold carts 28 are provided with the secondary mold-closing auxiliary mechanism.

[0081] The working process and principle of the present invention are:

[0082] During installation, the connecting plate 13 is positioned between adjacent partitions 12 and connected to the partitions 12 via latches 7. Several first compression blocks 14 are installed on top of the partitions 12, spaced side by side. Several second compression blocks 15 are installed on the left and right sides of the partitions 12, spaced side by side. Support plates 22 are installed on the left and right sides of the partitions 12, below the second compression blocks 15.

[0083] Before closing the mold, each mold on the mold carriage 28 is in its maximum open position, with the spacing between adjacent partitions 12 at its maximum, and the latch 7 located at the outermost end of the first connecting groove 4. The bottom plate 25 is placed between adjacent partitions 12, with the end of the bottom plate 25 locked in the locking groove 6 of the connecting plate 13.

[0084] To begin the first mold closing operation, cylinder 10 activates, pushing support plate 9 upward. After rising a certain distance, support plate 9 contacts the bottom of all connecting plates 13 on the same side and continues to push them upward. At this point, latch 7 moves downward relative to connecting plates 13, passing from first connecting groove 4 into the lowest end of second connecting groove 5. The outermost partition 12 is pushed first. Because latch 7 indicates the position of partition 12, and its range of motion is limited by the width of second connecting groove 5 on connecting plate 13, with connecting plate 13 held up, the outermost partition 12 can only close to its adjacent partitions 12 a certain distance (this distance is determined by the inner distance between the two second connecting grooves 5 on connecting plate 13). After the first mold closing operation of the outermost mold is completed, the outermost partition 12 continues to be pushed, pushing the adjacent partitions 12 through connecting plate 13. This process continues in this manner, completing the first mold closing operation of the remaining molds.

[0085] After the first mold closing of all molds on the mold cart 28 is complete, the worker removes the top plate 26 from the groove 21 of the first pressure block 14 and places it atop the adjacent bulkhead 12, where it is held in place by the first pressure blocks 14 on either side. The side plates 27, located on the support plate 22 (which is double-limited by the protrusion and groove 21), are also removed and placed on the left and right sides of the adjacent bulkhead 12, where they are held in place by the second pressure blocks 15 on either side. After the top plate 26 and side plates 27 are loaded, the second mold closing begins. The cylinder 10 first activates, moving the support plate 9 and all connecting plates 13 downward, while the latch 7 moves upward relative to the connecting plates 13. This time, the latch 7 enters the first connecting groove 4 from the second connecting groove 5. Next, the outermost bulkhead 12 is pushed again. Because the first connecting groove 4 is wider than the second connecting groove 5, the external force allows the latch 7 to continue moving toward the center of the connecting plate 13, further reducing the distance between adjacent bulkheads 12. During this process, the top plate 26 is guided and pressurized by the first pressing block 14, and the side plate 27 is guided and pressurized by the second pressing block 15, contacting and pressing the adjacent partition plate 12 and bottom plate 25 to form a closed cavity for grouting. At this point, the second mold closing is completed.

[0086] During the mold opening and closing process, the slots 6 always hold both ends of the bottom plate 25. The difference is that when the connecting plate 13 is lifted, the bottom plate 25 enters the slots 6 to a greater depth, while when the connecting plate 13 is lowered, the bottom plate 25 enters the slots 6 to a shallower depth. Therefore, the bottom plate 25 is constantly controlled by the connecting plate 13 and maintained in the middle of the adjacent partitions 12. The advantage of this design is that when the mold is opened, the connecting plate 13 carries the bottom plate 25 and the product away from the adjacent partitions 12, and when the mold is closed, the bottom plate 25 is always kept in the middle of the adjacent partitions 12, achieving two goals at one stroke.

[0087] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
