DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Example 1, reference Figure 1 to Figure 12 , which is the first embodiment of the present invention, and provides an extrusion molding device for producing concrete blocks, which includes a main unit 100, including a block molding machine 101, an extrusion device 102 arranged on the block molding machine 101, a lifting plate 103 arranged below the extrusion device 102, a mold frame 104 arranged on the lifting plate 103 and located below the extrusion device 102, a plurality of partitions 105 arranged on the inner wall of the mold frame 104, a concrete unloading device 106 arranged on the block molding machine 101 and located on one side of the mold frame 104, and a block conveying device 107 arranged on one side of the block molding machine 101, and, The mold cleaning unit 200 includes a bottom frame 201 arranged below the mold frame 104, a plurality of extension frames 202 arranged on the bottom frame 201, a driving assembly 203 arranged inside the bottom frame 201, a scraping assembly 204 arranged on the driving assembly 203 and connected to the extension frame 202, a blocking assembly 205 arranged on the mold frame 104, a clamping assembly 206 arranged on the driving assembly 203 and connected to the blocking assembly 205, and two vertical elastic assemblies 207 arranged on the lifting plate 103 and connected to the blocking assembly 205.

[0034] The extrusion device 102 includes a top plate 102a disposed on the block forming machine 101, four guide rods 102b disposed on the block forming machine 101 and connected to the top plate 102a, a movable plate 102c disposed on the four guide rods 102b, a block extrusion member 102d disposed on the movable plate 102c and located above the mold frame 104, and an upper hydraulic cylinder 102e disposed on the top plate 102a and connected to the movable plate 102c, a lifting plate 103 is slidably connected to the four guide rods 102b, and a lower hydraulic cylinder 102f connected to the block forming machine 101 is disposed at the bottom of the lifting plate 103; The concrete unloading equipment 106 includes a concrete unloading bin 106a provided on the block forming machine 101, a fixed plate 106b provided on the block forming machine 101, a concrete material box provided above the fixed plate 106b, and a lateral hydraulic cylinder 106d provided on the block forming machine 101 and fixedly connected to the concrete material box, wherein the bottom of the concrete material box and the top of the fixed plate 106b are in a sliding fit connection relationship; At least four groups of partitions 105 are arranged inside the mold frame 104, and the mold frame 104 is equally divided into five spaces for holding concrete by the four groups of partitions 105. The number of the extension frames 202 is set to five groups, which is consistent with the number of spaces for holding concrete in the mold, and the bottom of the extension frame 202 is fixedly connected to the top of the bottom frame 201.

[0035] When in use, since the production line of the block forming machine 101 continuously conveys a placing plate for placing concrete blocks under the mold frame 104 by means of numerical control, the placing plate is in a position directly below the mold before the concrete unloading device 106 injects concrete into the mold frame 104, and before the concrete unloading device 106 is used to inject concrete into the mold frame 104, the lower hydraulic cylinder 102f is started to make the mold frame 104 drop to a position that is closely fitted with the top of the placing plate, and the placing plate can be used together with the mold frame 104 to hold the concrete injected into the mold frame 104 and the blocks after extrusion molding; The concrete is discharged to the concrete material box through the concrete discharge bin 106a on the concrete discharge equipment 106, and then the lateral hydraulic cylinder 106d is started to push the concrete material box to move parallel to the direction of the mold frame 104 on the fixed plate 106b. During the movement, the concrete material box will gradually move from the fixed plate 106b to the top of the mold frame 104 until the concrete material box is completely moved to the space inside the mold for holding concrete, and then the concrete in the concrete material box can be discharged into the mold frame 104, and then the lateral hydraulic cylinder 106d is controlled to move the concrete material box in the opposite direction to the original position for subsequent use; After the concrete is injected into the mold frame 104, the upper hydraulic cylinder 102e drives the extrusion piece to move downward and enter the mold frame 104 to extrude the concrete. After the extrusion piece is formed, the upper hydraulic cylinder 102e is controlled to raise and reset the extrusion piece, and then the lower hydraulic cylinder 102f is controlled to drive the lifting plate 103 and the mold frame 104 to rise above the block. After the block is formed and placed on the placement plate, the placement plate and the blocks placed on it are automatically transported to the block conveying device 107 for subsequent processing operations on the production line. When the mold frame 104 needs to be cleaned after use, the bottom frame 201 and the insertion frame 202 are moved upward to a suitable height by the hydraulic rod 203e, and then the mold frame 104 is driven down by the upper hydraulic cylinder 102e until the bottom of the enclosure assembly 205 on the mold frame 104 is slightly in contact with the top of the bottom frame 201. At this time, the scraping assembly 204 is extended in the insertion frame 202 by the driving assembly 203 to completely fit the inner wall of the mold frame 104 and the side of the partition 105. When the bottom of the enclosure assembly 205 is in slight contact with the top of the bottom frame 201, the scraping assembly 204 is extended to a position slightly higher than the top of the mold frame 104. The lower hydraulic cylinder 102f is then used to drive the lifting plate 103 and the mold frame 104 to move upward, and the scraping assembly 204 can clean the inner wall of the mold frame 104 and the partition The solidified concrete remaining on or attached to the side of the plate 105 is scraped off. When the scraping component 204 is extended by the driving component 203, the clamping component 206 is also simultaneously extended into and clamped on the enclosure component 205 to fix the enclosure component 205. Then, when the mold frame 104 is raised and cleaned, the mold frame 104 and the surrounding area of ​​the insertion frame 202 are always protected by the enclosure component 205, thereby preventing the scraped and fallen solidified concrete from being scattered everywhere. After the mold frame 104 is cleaned, the driving component 203 is controlled to run in reverse, so that the scraping component 204 can be retracted into the insertion frame 202. At the same time, the clamping component 206 will also be free from the restriction on the enclosure component 205. When the enclosure component 205 is free from the restriction of the clamping component 206, it will be automatically reset by the vertical elastic component 207 for subsequent continued use.

[0036] Example 2, reference Figure 1 to Figure 10 , which is the second embodiment of the present invention, is different from the previous embodiment in that it includes: a driving assembly 203 includes a cover frame 203a arranged inside the bottom frame 201, a screw rod 203b arranged inside the extending frame 202, a motor 203c arranged inside the cover frame 203a and connected to the screw rod 203b, and a linkage belt 203d arranged between every two adjacent screw rods 203b, and a hydraulic rod 203e connected to the block forming machine 101 is arranged at the bottom of the bottom frame 201.

[0037] The number of the screw rods 203b is consistent with the number of the extension frame 202, and the top of the screw rod 203b is rotatably connected to the top of the inner cavity of the extension frame 202 through a bearing, the bottom end of the screw rod 203b in the middle position sequentially penetrates the bottom frame 201 and the cover frame 203a and is fixedly connected to the output shaft of the motor 203c, and the bottom ends of the remaining four screw rods 203b sequentially penetrate the bottom frame 201 and the cover frame 203a and are rotatably connected to the bottom of the inner cavity of the bottom frame 201 through a bearing, and the top and bottom of the outer surface of the screw rod 203b are respectively set to two opposite sections. The threaded part 203 is provided so that the driving component 203 can drive the clamping component 206 and the scraping component 204 to extend and retract synchronously. The motor 203c is fixedly connected to the bottom of the inner cavity of the bottom frame 201. The screw rod 203b is provided with a positioning wheel used in conjunction with the linkage belt 203d to limit the linkage belt 203d. The two adjacent linkage belts 203d are staggered in an upper and lower arrangement. Through the arrangement of the hydraulic rod 203e, when the mold cleaning unit 200 does not clean the mold frame 104, it can be stored at a height that does not affect the normal operation of the block forming machine 101.

[0038] Furthermore, the scraping assembly 204 includes an upper threaded plate 204a arranged on the screw rod 203b, a first limiting plate 204b and a second limiting plate 204c arranged inside the frame 202, and a first limiting groove 204d and a second limiting groove 204e arranged on the first limiting plate 204b and the second limiting plate 204c.

[0039] Among them, the upper threaded plate 204a is threadedly connected to the top of the outer surface of the screw rod 203b, the first limit plate 204b is fixedly connected to the left and right walls of the extension frame 202, the second limit plate 204c is fixedly connected to the front and rear walls of the extension frame 202, and the height of the second limit plate 204c is higher than the height of the first limit plate 204b, and each first limit plate 204b is provided with a first limit groove 204d on the left and right sides of the bottom, and each second limit plate 204c is provided with a second limit groove 204e on the front and rear sides of the bottom.

[0040] Furthermore, the scraping assembly 204 also includes two upper first openings 204f arranged on the extension frame 202 and located below the first limiting plate 204b, and two upper second openings 204g arranged on the extension frame 202 and located below the second limiting plate 204c, and the interior of the upper first opening 204f is provided with a first scraper 204f-1 that cooperates with the first limiting groove 204d, and the interior of the upper second opening 204g is provided with a second scraper 204g-1 that cooperates with the second limiting groove 204e.

[0041] Among them, the first scraper 204f-1 and the upper first opening 204f are slidably connected, and the first scraper 204f-1 and the first limiting groove 204d are slidably connected, the second scraper 204g-1 and the upper second opening 204g are slidably connected, and the second scraper 204g-1 and the second limiting groove 204e are slidably connected. The first limiting groove 204d and the second limiting groove 204e can limit the moving directions of the first scraper 204f-1 and the second scraper 204g-1, so that the first scraper 204f-1 and the second scraper 204g-1 can extend or retract into the frame 202.

[0042] Furthermore, the scraping assembly 204 also includes an upper first rotating plate 204f-2 arranged on the first scraper 204f-1 and connected to the upper threaded plate 204a, and an upper second rotating plate 204g-2 arranged on the second scraper 204g-1 and connected to the upper threaded plate 204a. The upper first opening 204f, the first scraper 204f-1 and the upper second opening 204g, the second scraper 204g-1 are arranged alternately up and down.

[0043] Among them, the tops of the two upper first rotating plates 204f-2 are rotatably connected to the opposite sides of the two first scrapers 204f-1 through rotating parts, and the bottoms of the two upper first rotating plates 204f-2 are rotatably connected to the left and right sides of the upper threaded plate 204a through rotating parts; the tops of the two upper second rotating plates 204g-2 are rotatably connected to the opposite sides of the two second scrapers 204g-1 through rotating parts, and the bottoms of the two upper second rotating plates 204g-2 are rotatably connected to the front and rear sides of the upper threaded plate 204a through rotating parts. By staggering the first scraper 204f-1 and the second scraper 204g-1 up and down, when the driving component 203 drives the scraping component 204 to retract and extend into the frame 202, there is no conflict between the first scraper 204f-1 and the second scraper 204g-1, and the second scraper 204g-1 is set to a special shape matching the inner wall of the mold frame 104.

[0044] During use, when the mold frame 104 needs to be cleaned after use, the bottom frame 201 and the insertion frame 202 are moved upward to a suitable height by the hydraulic rod 203e, and then the mold frame 104 is driven down by the upper hydraulic cylinder 102e until the bottom of the enclosure assembly 205 on the mold frame 104 is slightly in contact with the top of the bottom frame 201. At this time, the motor 203c is started to drive the screw rod 203b and the linkage belt 203d to rotate, thereby driving the upper threaded plate 204a to move upward, thereby driving the upper first rotating plate 204f-2 and the upper second rotating plate 204g-2 to rotate, and respectively pushing the first scraper 204f- 1 and the second scraper 204g-1 are extended into the extension frame 202 until they are completely in contact with the inner wall of the mold frame 104 and the side of the partition 105. Since the bottom of the enclosure assembly 205 is in slight contact with the top of the bottom frame 201, the first scraper 204f-1 and the second scraper 204g-1 will be just slightly higher than the top of the mold frame 104 after being extended. At this time, the lower hydraulic cylinder 102f is used to drive the lifting plate 103 and the mold frame 104 to move upward, and the first scraper 204f-1 and the second scraper 204g-1 can scrape off the solidified concrete remaining or attached to the inner wall of the mold frame 104 and the side of the partition 105.

[0045] The rest of the structure is the same as that of Example 1.

[0046] Example 3, reference Figure 1 to Figure 11 , which is the third embodiment of the present invention. Different from the previous embodiment, it includes: the enclosure assembly 205 includes a square enclosure 205a arranged outside the mold frame 104, a square corrugated enclosure 205b arranged on the square enclosure 205a and connected to the mold frame 104, a storage cavity 205c arranged inside the partition 105, a vertical baffle 205d arranged inside the storage cavity 205c and connected to the square enclosure 205a, and a corrugated baffle 205e arranged on the vertical baffle 205d and connected to the inner wall of the storage cavity 205c.

[0047] Among them, the square enclosure 205a is set at a position slightly lower than the lifting plate 103, the top of the square corrugated enclosure 205b is fixedly connected to the mold frame 104, the bottom of the square corrugated enclosure 205b is fixedly connected to the top of the square enclosure 205a, the storage cavity 205c is opened at the bottom of the partition 105, the bottom of the front and rear sides of the vertical baffle 205d are fixedly connected to the front and rear walls of the square enclosure 205a through the connecting block, the vertical baffle 205d is fixedly connected to the corrugated baffle 205e, and the top of the corrugated baffle 205e is fixedly connected to the top of the inner cavity of the storage cavity 205c. Since the front and rear sides of the vertical baffle 205d are It is fixedly connected to the square enclosure 205a through a connecting block, but because the enclosure component 205 is generally at a height lower than the mold frame 104 due to the elastic force of the vertical elastic component 207, and the mold frame 104 needs to be lowered to fit with the placement plate when concrete needs to be injected, the enclosure component 205 needs to move upward a short distance when fitting with the placement plate, and then a vertical movable groove that cooperates with the connecting block is opened at the bottom of the partition 105, so as to provide a short space for the connecting block on the vertical baffle 205d to move upward; the corrugated baffle 205e and the square corrugated enclosure 205b are both set to be retractable material.

[0048] Furthermore, the clamping assembly 206 includes a receiving frame 206a disposed on the bottom frame 201 and located at the periphery of the extending frame 202, a movable opening 206b disposed on the receiving frame 206a, and a clamping plate 206c disposed inside the movable opening 206b.

[0049] Among them, the material receiving frame 206a is fixedly connected to the top of the bottom frame 201 and is located at the outer periphery of the extension frame 202. The clamping plate 206c and the movable opening 206b are slidably connected. The side of the material receiving frame 206a close to the partition 105 is set with a length that contacts the partition 105. The side of the two material receiving frames 206a at the upper edge of the bottom frame 201 close to the square enclosure 205a is set with a length that contacts the square enclosure 205a, so that when the scraping component 204 removes the solidified concrete, the removed solidified concrete can be discharged just through the material receiving frame 206a.

[0050] Furthermore, the clamping assembly 206 also includes a lower threaded plate 206d arranged on the screw rod 203b, a lower rotating plate 206e arranged on the clamping plate 206c and connected to the lower threaded plate 206d, and a clamping groove 206f arranged on the square enclosure 205a and the vertical baffle 205d and matched with the clamping plate 206c, and a blanking port 206e-1 is opened on the lower rotating plate 206e.

[0051] Among them, the lower threaded plate 206d and the screw rod 203b are threadedly connected, the top and bottom of the lower rotating plate 206e are rotatably connected to the clamping plate 206c and the lower threaded plate 206d respectively through rotating parts, the clamping plate 206c and the clamping groove 206f are slidably connected, and the number of the clamping grooves 206f is set to be several. Since a part of the clamping plate 206c is inside the movable opening 206b when it is extended and retracted, the moving direction of the clamping plate 206c can be limited by the setting of the movable opening 206b. The number of the blanking openings 206e-1 is set to be multiple. When the clamping plate 206c is in a state of being connected to the clamping groove 206f, the blanking opening 206e-1 is completely presented in the range of the movable opening 206b, so that the cleared solidified concrete can be discharged.

[0052] Furthermore, the vertical elastic force assembly 207 includes two slots 207a arranged on the lifting plate 103, two fixed brackets 207b arranged on the lifting plate 103, a vertical rod 207c arranged on the fixed bracket 207b and located inside the slot 207a, a connecting bracket 207d arranged on the square enclosure 205a and connected to the vertical rod 207c, and a return spring 207e arranged on the connecting bracket 207d and connected to the vertical rod 207c.

[0053] Among them, since the lifting plate 103 is set in a "U" shape, the lifting plate 103 is sleeved on the outer periphery of the enclosure component 205, and a certain gap is left between the inner circle of the lifting plate 103 and the enclosure component 205, the notch 207a is opened at the top of the lifting plate 103, and the notch 207a and the inner circle of the lifting plate 103 are in an open state; the fixing bracket 207b is fixedly connected to the top of the lifting plate 103, and the fixing bracket 207b is located on one side of the notch 207a, and the top of the vertical rod 207c is fixedly connected to the fixing bracket 207b, and the vertical rod 207c is fixedly connected to the fixing bracket 207b. The bottom end of the vertical rod 207c is fixedly connected to a limiting block, and the connecting bracket 207d is fixedly connected to one side of the square enclosure 205a. The connecting bracket 207d and the vertical rod 207c are slidably connected. When the enclosure assembly 205 is connected to the vertical elastic assembly 207 and the bottom of the enclosure assembly 205 is not subject to any restriction, a certain rising space for the connecting bracket 207d is still reserved on the vertical rod 207c, so that when the mold frame 104 is injected with concrete, it needs to contact the placement plate, thereby providing the enclosure assembly 205 with rising space.

[0054] Furthermore, a material outlet 208 communicating with the bottom frame 201 is provided on the receiving frame 206a, and material discharge outlets 209 are provided at the bottom of the bottom frame 201 and at the front and rear sides of the cover frame 203a.

[0055] Among them, the discharge port 208 and the discharge port 209 are both convenient for discharging the scraped solidified concrete, and through the setting of the discharge port 209, a trash basket for containing solidified concrete impurities can be placed in advance below the block forming machine 101 and directly below the bottom frame 201, so that the solidified concrete can be collected after being discharged from the discharge port 209 for subsequent cleaning, further reducing the workload of the staff.

[0056] When in use, as the drive assembly 203 drives the scraper assembly 204 to extend, the rotation of the screw rod 203b will also drive the lower threaded plate 206d to descend, drive the lower rotating plate 206e to rotate and push the clamping plate 206c to clamp into the clamping groove 206f, thereby fixing the enclosure assembly 205. Then, when the mold frame 104 rises and is cleaned, the mold frame 104 and the surrounding area of ​​the insertion frame 202 are always protected by the enclosure assembly 205, thereby preventing the scraped and fallen solidified concrete from scattering everywhere. After the mold frame 104 is cleaned, the drive assembly 203 is controlled to run in reverse, so that the scraper assembly 204 can be retracted into the inside of the insertion frame 202, and the clamping assembly 206 will also be free from the restriction on the enclosure assembly 205. When the enclosure assembly 205 is free from the restriction of the clamping assembly 206, it will automatically reset through the vertical elastic assembly 207 for subsequent continued use.

[0057] The rest of the structure is the same as that of Example 2.
