Description

Technical Field

[0001] The utility model relates to the technical field of concrete precast block molds, and specifically relates to a concrete precast block mold with automatic feeding. Background Technique

[0002] There are many types of concrete precast blocks, such as concrete precast bricks, concrete precast covers, concrete precast slope protection bricks, and so on.

[0003] The production processes of concrete precast block components are basically the same, and they are basically all formed through molds; the molds are divided into an upper mold and a lower mold. After the upper mold and the lower mold are closed, grouting is carried out. After the concrete solidifies, the molds are separated, and the concrete blocks in the molds can be taken out to obtain precast products.

[0004] At present, the molds used in large-scale continuous production lines in the industry are all electrically controlled to achieve mold closing and mold opening. Specifically, the stroke of a pneumatic system or a hydraulic system can be set on the main machine, and the mold closing and mold opening of the mold can be achieved by cooperating with the mechanical structure; moreover, the main machine will also establish communication with the grouting system. After the stroke of the system reaches the set value, it is defaulted that the mold is completely closed, and then grouting is started. However, the mold is inevitably offset by the influence of precast components all year round. Especially, the lower mold bears the weight over the years, and it will sink continuously as time goes by; and the specific data of the sinking is also uncertain; ultimately, there is a deviation between the actual stroke of mold closing and the initial design stroke (the actual stroke is greater than the design stroke); if this deviation is not corrected, it will lead to incomplete mold closing and serious problem of grout overflow; only by frequent correction can the operating stroke of the system be made to match the actual mold closing stroke, and frequent measurement and correction will affect the production progress.

[0005] Some manufacturers in the industry have imagined adding a ranging module (such as an infrared ranging device) between the upper mold and the lower mold. However, due to the relatively harsh production site environment of concrete precast block components, it is often accompanied by dripping, overflowing, and spilling of uncoagulated concrete slurry and liquid. Once it adheres to the ranging module, it will directly interfere with the normal operation of the rangefinder; moreover, the solidified concrete slurry adheres to the rangefinder and is not easy to remove, because improper removal will cause damage to the rangefinder.

[0021] Wherein, the top end of the L-shaped slider is set as an inclined surface, which fits against the side surface of the trapezoidal slider, and the elastic force of the first spring is greater than that of the second spring.

[0022] As a further solution of the present utility model:

[0023] The reset assembly includes a support rod fixedly arranged on the side wall of the upper mold and a turntable rotatably arranged on the support rod;

[0024] One side wall of the turntable is fixedly provided with a sliding column. An arc-shaped groove concentric with the turntable is formed on the side wall of the upper mold.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0041] Please refer to Figures 1 to 8, in the embodiment of the present utility model, a concrete precast block mold for automatic feeding includes a lower mold 1 and an upper mold 2 that can be opened and closed with the lower mold 1. A feeding pipe 3 is penetrated and arranged in the upper mold 2, and a baffle 4 is horizontally slidably arranged on the feeding pipe 3. The baffle 4 can open or close the feeding pipe 3;

[0042] A grouting control component is arranged on the upper mold 2. The grouting control component is connected to the baffle 4. During the process that the upper mold 2 approaches and closes to the lower mold 1, the grouting control component will drive the baffle 4 to slide horizontally and make the feeding pipe 3 in an open state, so that concrete enters the lower mold 1 from the feeding pipe 3 for prefabrication;

[0043] A reset component is further arranged between the upper mold 2 and the lower mold 1. The reset component is connected to the grouting control component. When the upper mold 2 and the lower mold 1 are separated after prefabrication is completed, the reset component will drive the baffle 4 to slide back through the grouting control component, so that the feeding pipe 3 is in a closed state.

[0044] In this solution, through the arranged grouting control component, automatic control of grouting can be realized through mechanical transmission at the moment when the upper mold 2 and the lower mold 1 are completely closed; grouting will only be triggered after the upper mold 2 and the lower mold 1 are completely closed, and there is no need to set a stroke value; even if the lower mold 1 sinks and the sinking amount changes continuously, it can be ensured that the whole mold will only grout after the upper and lower molds are completely closed; that is, there is no need to frequently correct the stroke parameters, nor to worry about the normal opening and closing of grouting.

[0045] As a further solution of the present utility model, the grouting control component includes a first sleeve 5 fixedly arranged on the upper mold 2 and a first sliding rod 6 slidably matched with the first sleeve 5. A first spring 7 is arranged inside the first sleeve 5;

[0046] The first spring 7 always makes the first sliding rod 6 have a tendency to extend out of the first sleeve 5. A moving plate 8 is fixedly arranged on the first sliding rod 6;

[0047] Wherein, the bottom end of the first sliding rod 6 is located below the bottom end of the upper mold 2.

[0048] In this embodiment, since the bottom end of the first sliding rod 6 is located below the bottom end of the upper mold 2, during the process that the upper mold 2 approaches and closes to the lower mold 1, the first sliding rod 6 will move upward under the action of the lower mold 1. During this process, the first sliding rod 6 will drive the moving plate 8 to move upward and further compress the first spring 7.

[0049] As a further solution of the present utility model, a first sliding groove 9 is formed on the side wall of the upper die 2, a trapezoidal slider 10 is slidably arranged in the first sliding groove 9, a guiding frame plate 11 is fixedly arranged on the trapezoidal slider 10, and the moving plate 8 is located inside the guiding frame plate 11 and is slidably matched with each other;

[0050] Wherein, the first sliding groove 9 is arranged at an angle of 45 degrees with the horizontal plane.

[0051] In this embodiment, as Figure 4 shown, during the upward movement of the moving plate 8, the moving plate 8 will cause the trapezoidal slider 10 to slide in the first sliding groove 9 by slidingly cooperating with the guiding frame plate 11. Since the first sliding groove 9 is inclined, the trapezoidal slider 10 will also move relatively with the L-shaped slider 13 during the sliding process. When the upper die 2 and the lower die 1 are completely closed, that is, when the L-shaped slider 13 stops moving, at this time, the top end of the L-shaped slider 13 just fits with the bottom end of the trapezoidal slider 10.

[0052] As a further solution of the present utility model, a second sliding groove 12 is horizontally formed on the side wall of the upper die 2, an L-shaped slider 13 is slidably arranged in the second sliding groove 12, a second sliding rod 15 is horizontally fixedly arranged on the right side wall of the L-shaped slider 13, a second sleeve 14 is fixedly arranged on the upper die 2, and the second sliding rod 15 is slidably matched with the second sleeve 14;

[0053] A second spring 16 that always makes the second sliding rod 15 have a tendency to move leftward is arranged inside the second sleeve 14, and a connecting rod 17 is fixedly connected between the L-shaped slider 13 and the baffle 4;

[0054] Wherein, the top end of the L-shaped slider 13 is arranged as an inclined surface and is in contact with the side surface of the trapezoidal slider 10, and the elastic force of the first spring 7 is greater than the elastic force of the second spring 16.

[0055] In this embodiment, as Figure 4 shown, at the moment when the top end of the L-shaped slider 13 just fits with the bottom end of the trapezoidal slider 10, due to the absence of the acting force of the trapezoidal slider 10, the second spring 16 will release its elastic force and push the L-shaped slider 13 to move leftward under the limitation of the second sliding groove 12 through the second sliding rod 15;

[0056] During the leftward movement of the L-shaped slider 13, the baffle 4 will be driven to slide horizontally leftward in the injection pipe 3 through the connecting rod 17, so that the injection pipe 3 is opened, and the concrete slurry enters the lower die 1 through the injection pipe 3;

[0057] Since the elastic force of the first spring 7 is greater than the elastic force of the second spring 16, therefore, the L-shaped slider 13 in the initial state cannot push the trapezoidal slider 10.

[0058] As a further solution of the present utility model, the reset assembly includes a support rod 18 fixedly arranged on the side wall of the upper mold 2 and a turntable 19 rotatably arranged on the support rod 18;

[0059] One side wall of the turntable 19 is fixedly provided with a sliding column 20. An arc-shaped groove 21 concentric with the turntable 19 is formed on the side wall of the upper mold 2. One end of the sliding column 20 is located inside the arc-shaped groove 21 and is in sliding fit. The left end of the L-shaped slider 13 is in contact with the sliding column 20.

[0060] In this embodiment, as Figure 6 shown, during the process of the L-shaped slider 13 moving leftward, the sliding column 20 will slide clockwise in the arc-shaped groove 21 under the pushing action of the L-shaped slider 13, causing the turntable 19 to rotate clockwise following the sliding column 20.

[0061] As a further solution of the present utility model, a ratchet ring 22 is rotatably arranged on the outer wall of the turntable 19. A locking ratchet 23 that cooperates with the ratchet ring 22 is rotatably arranged on the other side wall of the turntable 19. An elastic piece 24 is fixedly arranged on the other side wall of the turntable 19. The elastic piece 24 can make the locking ratchet 23 and the ratchet ring 22 always remain in a contact state.

[0062] In this embodiment, as Figure 4 shown, since the elastic piece 24 can make the locking ratchet 23 and the ratchet ring 22 always remain in a contact state, when the turntable 19 rotates clockwise, the ratchet ring 22 will be driven to rotate clockwise simultaneously by the locking ratchet 23.

[0063] As a further solution of the present utility model, a gear 25 is rotatably arranged on the outer wall of the support rod 18. The gear 25 is fixedly connected to the ratchet ring 22 through a fixing rod 26. A toothed plate 27 that cooperates with the gear 25 is fixedly arranged on the top surface of the lower mold 1.

[0064] In this embodiment, during the process of the upper mold 2 approaching and closing the lower mold 1, the gear 25 will engage with the toothed plate 27. The gear 25 will rotate clockwise under the action of the toothed plate 27, and at the same time, the ratchet ring 22 will also be driven to rotate synchronously;

[0065] When the upper mold 2 is separated from the lower mold 1, the gear 25 will rotate counterclockwise under the action of the toothed plate 27, and the ratchet ring 22 will rotate counterclockwise following the gear 25. Due to the interaction between the ratchet ring 22 and the locking ratchet 23, the turntable 19 will also rotate counterclockwise, causing the sliding column 20 to slide counterclockwise in the arc-shaped groove 21. When the sliding column 20 slides counterclockwise, it will push the L-shaped slider 13 to move horizontally to the right;

[0066] During the process of the L-shaped slider 13 moving rightward, it will drive the baffle 4 to reset, so that the material injection pipe 3 is closed. When the inclined surface of the L-shaped slider 13 fits with the trapezoidal slider 10, the trapezoidal slider 10 will reset under the action of the first spring 7, thereby enabling the first sliding rod 6 to reset, which is convenient for the next material injection.

[0067] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
