Description

Technical Field

[0001] The invention relates to the technical field of block production, in particular to a mould for producing concrete blocks. Background Art

[0002] Blocks are larger building blocks than clay bricks. They are man-made blocks made from concrete, industrial waste (slag, fly ash, etc.), or local materials. They are larger than bricks and offer advantages such as simple equipment and fast construction speed, meeting the requirements of wall reform in the development of building industrialization. Block forming machines are used to produce blocks. Using different molds, they can produce blocks of various shapes and sizes. To facilitate demolding, lubricating oil must be applied to the mold box.

[0003] Currently, the main methods of oiling are spraying and manual oiling. However, the block forming mold box is large, and the nozzle cannot fully cover the mold box. During use, the nozzle position must be constantly moved to achieve full spraying, resulting in poor spray uniformity. Manual oiling is time-consuming, labor-intensive, and inefficient. After searching, a patent with publication number CN113084979B discloses an integrated mold oiling and pouring device for aerated concrete block production. By providing an oiling roller, the mold can be oiled. When the oiling roller moves to one end of the mold, an oiling mechanism replenishes the oiling roller with release oil, thereby achieving automatic oiling. Although this method can achieve the purpose of saving time and effort, because the oiling mechanism is located at the left end of the mold, the amount of oil in the oiling roller at the left end of the mold is always greater than when it moves to the right end of the mold, making it difficult to evenly apply the oil in the mold. In view of this, we propose a mold for concrete block production. Summary of the Invention

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figures 1-10 , a technical solution provided by the present invention:

[0040] A mold for producing concrete blocks, comprising a base 1, on which a mold box 2 is fixedly mounted;

[0041] Support mechanism 3, support mechanism 3 is arranged on base 1;

[0042] The oil spraying mechanism 4 is arranged on the supporting mechanism 3 and is used to spray oil into the mold box 2;

[0043] The smearing mechanism 5 is provided on the supporting mechanism 3 and is used to smear the oil in the mold box 2;

[0044] And a steering mechanism 6 is used to adjust the angle between the coating mechanism 5 and the oil spraying mechanism 4.

[0045] In this embodiment, the support mechanism 3 includes a sliding frame 31, and the sliding frame 31 is slidably mounted on the base 1. Figure 2As shown, two slide rails 7 are fixedly installed on the top of the base 1. The two slide rails 7 are symmetrically distributed with the center line of the mold box 2 as the axis of symmetry. The two slide rails 7 are slidably matched with slide seats 8. The tops of the two slide seats 8 are fixedly connected to the bottom of the sliding frame 31. The slide seats 8 slide on the slide rails 7, which can drive the sliding frame 31 to move left and right. When in use, the sliding frame 31 can be pushed manually, or a linear motor can be installed on the slide rails 7 to provide power for the movement of the slide 8. A cylinder 32 is fixedly installed on the top of the sliding frame 31, and a lifting plate 33 is fixedly installed on the output end of the cylinder 32. A lifting seat 34 is fixedly installed on the bottom of the lifting plate 33. A round rod 35 is fixedly installed on the lifting seat 34, and a support plate 36 is fixedly installed on the end of the round rod 35 away from the lifting seat 34 to support the oil injection mechanism 4 and the coating mechanism 5.

[0046] Furthermore, the oil injection mechanism 4 includes a mounting plate 41, which is fixedly mounted on the support plate 36. A plurality of nozzles 42 are fixedly mounted on the bottom of the mounting plate 41. The plurality of nozzles 42 are arranged in a line at equal distances along the length direction of the mounting plate 41. The top of each nozzle 42 is connected to an oil outlet pipe 43, and the top of the oil outlet pipe 43 is connected to a diversion pipe 44. An oil pump 45 is fixedly mounted on the top of the sliding frame 31. The output end of the oil pump 45 is connected to one end of the diversion pipe 44 through a hose, and the input end of the oil pump 45 is connected to an oil tank (not shown in the figure) through a pipeline to provide lubricating oil to the nozzle 42.

[0047] In this embodiment, the smearing mechanism 5 includes a limit frame 51, which is fixedly mounted on the support plate 36. A limit slider 52 is slidably mounted on the inner wall of the limit frame 51. A connecting seat 53 is fixedly mounted on the side of the limit slider 52 away from the limit frame 51. By providing the limit frame 51 and the limit slider 52, the connecting seat 53 can be limited so that the connecting seat 53 can only move left and right. A fixed frame 54 is fixedly mounted on the bottom of the connecting seat 53. A brush plate 56 is detachably mounted on the fixed frame 54. The bottom of the brush plate 56 has bristles for evenly spreading the sprayed lubricating oil. A clamping assembly 55 is provided between the fixed frame 54 and the brush plate 56 to facilitate the installation and removal of the brush plate 56, thereby facilitating the cleaning and replacement of the brush plate 56.

[0048] Specifically, the clamping assembly 55 includes two fixed plates 551, which are both fixedly installed on the top of the brush plate 56, and the two fixed plates 551 are symmetrically distributed with the center line of the brush plate 56 as the axis of symmetry. A cross bar 552 is fixedly installed between the two fixed plates 551, and a groove 541 is provided at the bottom of the fixed frame 54. The cross bar 552 is inserted into the groove 541. There are two cross bars 552, and the two cross bars 552 are symmetrically distributed with the center line of the brush plate 56 as the axis of symmetry. The number and position of the grooves 541 are adapted to the cross bars 552. When the top surface of cross bar 552 contacts the top wall of groove 541, stopper 553 can be automatically reset under the action of the spring, thereby limiting the relative movement between cross bar 552 and groove 541, achieving the purpose of limiting the position of brush plate 56.

[0049] It is worth noting that the steering mechanism 6 includes a rotating sleeve 61, which is rotatably mounted on the round rod 35, and a swinging wall 62 is fixedly mounted on the rotating sleeve 61. A movable groove 621 is provided on the swinging wall 62, and a transmission rod 63 is provided in the movable groove 621. The transmission rod 63 is fixedly mounted on the connecting seat 53. When the rotating sleeve 61 rotates, it can drive the swinging wall 62 to swing. At this time, since the connecting seat 53 is limited by the limiting slider 52 and the limiting frame 51, the transmission rod 63 can slide in the movable groove 621 and drive the connecting seat 53 to move left and right. The connecting seat 53 drives the brush plate 56 to move through the fixed frame 54 to change the relative position between the brush plate 56 and the nozzle 42, so that when the nozzle 42 moves left and right, the brush plate 56 can move behind the nozzle 42, so as to facilitate the uniform smearing of the sprayed oil. The steering mechanism 6 also includes a mounting seat 67, on which a guide block 68 is fixedly mounted. The guide block 68 is slidably mounted on the inner wall of the lifting seat 34. A guide rod 610 is slidably mounted on the inner wall of the guide block 68. The guide rod 610 is fixedly mounted on the inner wall of the lifting seat 34 and is used to limit the position of the mounting seat 67, making the movement of the mounting seat 67 more stable. A drive frame 66 is fixedly mounted on the mounting seat 67, and a rack 65 is fixedly mounted on the drive frame 66. The surface of the rack 65 engages with a gear ring 64, and the gear ring 64 is fixedly mounted on the rotating sleeve 61. In addition, the steering mechanism 6 also includes a first bracket 611 and a second bracket 613. The first bracket 611 and the second bracket 613 are both fixedly mounted on the base 1. A first inclined plate 612 is fixedly mounted on the top of the first bracket 611, and a second inclined plate 614 is fixedly mounted on the top of the second bracket 613. The mounting seat 67 is a parallelogram. The second bracket 613 is higher than the first bracket 611. When the lifting seat 34 moves to the left end of the mold box 2, the inclined surface of the lower left side of the mounting seat 67 can contact the first inclined plate 612 and move upward under the push of the first inclined plate 612. The mounting seat 67 drives the rack 65 to move upward through the driving frame 66. The rack 65 drives the gear ring 64 to rotate clockwise at a certain angle through engagement. The gear ring 64 drives the swing wall 62 to rotate clockwise through the rotating sleeve 61, thereby driving the connecting seat 53 to move left, showing Figure 1 In the state shown, the brush plate 56 is located to the left of the spray head 42. When the sliding frame 31 moves rightward, the brush plate 56 can evenly spread the lubricating oil sprayed from the spray head 42. When the lifting base 34 moves to the right end of the mold box 2, the upper right inclined surface of the mounting base 67 can contact the second inclined plate 614 and, pushed by the second inclined plate 614, move downward, causing the brush plate 56 to move to the right of the spray head 42. When the sliding frame 31 moves leftward, the brush plate 56 can move behind the spray head 42 and evenly spread the lubricating oil sprayed there.

[0050] Preferably, a limiting assembly 69 is provided on the mounting seat 67 to prevent the mounting seat 67 from moving up and down without reason, thereby limiting the rack 65.

[0051] Specifically, the limiting assembly 69 includes a fixing rod 697, which is fixedly mounted on the inner wall of the mounting seat 67. A slide 692 is slidably mounted on the surface of the fixing rod 697. The surface of the slide 692 is elastically connected to the inner wall of the mounting seat 67 through a spring. A driving plate 691 is fixedly mounted on the slide 692. Both ends of the driving plate 691 pass through the mounting seat 67. When the mounting seat 67 moves to a specified position, the first inclined plate 612 and the second inclined plate 614 first contact the driving plate 691 and then contact the mounting seat 67, thereby releasing the limit of the mounting seat 67. By setting the fixing rod 697 and the slide 692, the driving plate 691 can be limited. A push block 693 is fixedly mounted on the side of the drive plate 691 proximal to the lift base 34. A plug plate 694 contacts the side of the push block 693 distal to the drive plate 691. Two sockets 341 are formed on the surface of the lift base 34. The end of the plug plate 694 proximal to the push block 693 is trapezoidal in shape. The other end of the plug plate 694 extends through the mounting base 67 and is inserted into one of the sockets 341, thereby limiting relative movement between the mounting base 67 and the lift base 34. The limit assembly 69 also includes a second fixing rod 696, which is fixedly mounted on the inner wall of the mounting base 67. A second slide plate 695 is slidably mounted on the surface of the second fixing rod 696. The surface of the second slide plate 695 is elastically connected to the inner wall of the mounting base 67 via a spring. The second slide plate 695 is fixedly mounted on the plug plate 694. When one end of the driving plate 691 is completely retracted into the interior of the mounting seat 67, the pushing block 693 can move away from the inserting plate 694. At this time, the inserting plate 694 will move toward the interior of the mounting seat 67 under the action of the spring and disengage from the socket 341. At this time, the mounting seat 67 can move up and down on the surface of the lifting seat 34. When one end of the driving plate 691 loses the external force restriction, it will pop outward under the action of the spring and drive the pushing block 693 to move. The elastic force of the spring on the slide 1 692 is greater than the elastic force of the spring on the slide 2 695, so that the pushing block 693 can push the inserting plate 694 outward through the inclined surface, so that one end of the inserting plate 694 enters the socket 341.

[0052] When using the concrete block production mold of the present invention, the cylinder 32 is first activated. The output end of the cylinder 32 drives the lifting plate 33 downward, which in turn drives the lifting seat 34 downward. The lifting seat 34 drives the round rod 35 downward, which in turn drives the support plate 36 downward. This in turn drives the spray head 42 and the coating mechanism 5 downward, so that the brush plate 56 on the coating mechanism 5 contacts the bottom wall of the mold box 2. The oil pump 45 is then activated, and the oil is supplied to the multiple oil outlet pipes 43 through the diverter pipe 44. The oil is then sprayed into the mold box 2 through the spray head 42. The sliding frame 31 moves left and right, driving the spray head 42 and the brush plate 56 left and right, thereby evenly spraying and smearing the oil inside the mold box 2. When the sliding frame 31 moves to the left to the specified position, the first inclined plate 612 will contact one end of the driving plate 691 and push the driving plate 691 into the mounting seat 67. When one end of the driving plate 691 is completely retracted into the mounting seat 67, the pushing block 693 can move away from the inserting plate 694. At this time, the inserting plate 694 will move toward the mounting seat 67 under the action of the spring and disengage from the socket 341. Then the first inclined plate 612 will contact the inclined surface at the lower left of the mounting seat 67. The mounting seat 67 moves upward under the push of the first inclined plate 612 and passes The driving frame 66 drives the rack 65 to move upward, and the rack 65 drives the gear ring 64 to rotate clockwise by a certain angle through engagement. The gear ring 64 drives the swing wall 62 to rotate clockwise through the rotating sleeve 61. Since the connecting seat 53 is limited by the limit slider 52 and the limit frame 51, the transmission rod 63 can slide in the movable groove 621 when the swing wall 62 rotates, thereby driving the connecting seat 53 to move to the left, and the connecting seat 53 drives the fixed frame 54 to move to the left, thereby driving the brush plate 56 to move to the left, so that the brush plate 56 moves to the left side of the nozzle 42. Then move the sliding frame 31 to the right. When the first inclined plate 612 moves away from the driving plate 691, the driving plate 691 will pop outward under the action of the spring and drive the pushing block 693 to move. The elastic force of the spring on the slide plate 1 692 is greater than the elastic force of the spring on the slide plate 2 695, so that the pushing block 693 can push the inserting plate 694 outward through the inclined surface, so that one end of the inserting plate 694 enters the socket 341, thereby limiting the mounting seat 67. During the movement of the sliding frame 31, the brush plate 56 can evenly spread the lubricating oil sprayed from the nozzle 42.
