Description

Technical Field

[0001] This utility model relates to the technical field of brick blank processing equipment, and in particular to a brick blank extrusion molding device. Background Technology

[0002] Chinese patent CN218314185U discloses a fly ash harmless treatment brick-making device, relating to the technical field of brick-making devices. This utility model includes a carrier box and a fixing frame. A fixing frame is fixed to both ends of the carrier box. A forming mechanism is assembled between the carrier box and the fixing frame. The forming mechanism is used to extrude and form a mixture of fly ash and brick blanks. The forming mechanism includes a support frame, a first motor, a lead screw, a brick blank trough, a brick-shaped through-slot, a power component, a pressure block, and a guide rod. A support frame is fixed to both ends of the top of the carrier box. Through the structural design of the forming mechanism, this utility model facilitates the extrusion and forming of fly ash and brick blanks, accelerating work efficiency and improving the efficiency of the device. Furthermore, through the structural design of the leveling mechanism, the device can level excess fly ash and brick blanks at the top of the brick blank trough, ensuring that the fly ash and brick blanks are at the same horizontal level inside the brick-shaped through-slot, resulting in bricks with uniform weight and size after forming.

[0003] However, the aforementioned brick-making device has obvious drawbacks: because it is equipped with only a single brick pressing mold, the operator must operate in a cyclical manner following the process of "filling - pressing - brick removal". During the filling and brick removal stages, the entire forming mechanism is idle, which not only significantly reduces production efficiency but also limits the number of bricks produced per unit time. Therefore, a brick blank extrusion forming device is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1 like Figure 1-6 As shown, the present invention proposes a brick blank extrusion molding device, comprising a support plate 6 and a brick blank forming mold 7. Support rods 16 are installed at the four corners of the bottom of the support plate 6. A support frame 2 is installed at the upper end of the support plate 6, and a pressing component is installed on the inner top wall of the support frame 2. There are two brick blank forming molds 7, and their bottoms slide in conjunction with the upper end of the support plate 6. The brick blank placement groove inside the brick blank forming mold 7 is adapted in size and position to the extrusion block of the pressing plate 5. A moving mechanism is installed at the upper end of the support plate 6, and the two moving ends of the moving mechanism are respectively connected to a connecting plate 17. Two brick forming molds 7 are detachably connected between the two connecting plates 17; it also includes two sets of through slots 18, the number of each set of through slots 18 is the same as the number of brick placement slots of the brick forming mold 7 and the positions are adapted to each other. The two sets of through slots 18 pass through the support plate 6 and are symmetrically distributed with the central axis of the support frame 2 as the axis of symmetry. An ejection component is installed at the bottom of the support plate 6 and at the bottom of each set of through slots 18; a controller 1 is installed on the outer wall of the support frame 2. The controller 1 is electrically connected to the moving mechanism, the pressing component and the ejection component respectively; the two brick forming molds 7 are arranged side by side.

[0025] It should be noted that the two brick forming molds 7 are initially positioned side by side, with one brick forming mold 7 directly below the pressing component and the other at the filling position. Infrared positioning ensures accurate positioning. At this time, the brick forming mold 7 in the working position completes the brick extrusion through the pressing component. Simultaneously, the worker fills the brick forming mold 7 at the filling position with brick material. After forming is completed, the moving mechanism drives the double molds to slide and switch positions. The mold with the material is moved to the working position, and the brick forming mold 7 moves to the material removal position and is locked by infrared positioning. The ejector component below the material removal position ejects the brick. After the worker removes the brick, the brick forming mold 7 can be filled again to enter the next cycle.

[0026] In this embodiment, the pressing component includes a first electric push rod 3, a guide rod 4, and a pressing plate 5. The middle part of the inner top wall of the support frame 2 is connected to the pressing plate 5 through the first electric push rod 3. The pressing end of the pressing plate 5 faces downward. Guide rods 4 are installed on the inner top wall of the support frame 2 on both sides of the first electric push rod 3. The guide rods 4 are arranged parallel to the first electric push rod 3.

[0027] It should be noted that the guide rod 4 can precisely limit the lifting trajectory of the pressing plate 5, preventing the pressing plate 5 from deviating during the pressing process and ensuring that the extruded block and the brick blank placement groove are accurately aligned.

[0028] In this embodiment, the moving mechanism includes a sliding rod 15, a sliding sleeve 14, a connecting rod 13, and an electric sliding sleeve 24. The two sides of the upper end of the support plate 6 are respectively connected to the sliding rod 15. The sliding sleeve 14 is slidably sleeved on the outer end face of one of the sliding rods 15, and the electric sliding sleeve 24 is slidably sleeved on the other sliding rod 15. The sides of the sliding sleeve 14 and the electric sliding sleeve 24 opposite to each other are respectively connected to the two connecting plates 17 through the connecting rod 13.

[0029] It should be noted that the electric sliding sleeve 24 acts as a power source to drive the connecting rod 13 on one side to move, and the sliding sleeve 14 on the other side moves in coordination, so that the two brick forming molds 7 can smoothly switch positions along the sliding rod 15, and alternately enter the working area of ​​the pressing component.

[0030] In this embodiment, multiple fixing bolts 22 are also included. Both ends of the connecting plate 17 are provided with snap-fit ​​grooves 1701. Both ends of the brick forming mold 7 are provided with insert brackets 12. The insert brackets 12 are snapped into the snap-fit ​​grooves 1701. Multiple fixing bolts 22 pass through the insert brackets 12 and the connecting plate 17 and extend to the inner wall of the brick forming mold 7. The brick forming mold 7 is threadedly connected to the fixing bolts 22.

[0031] It should be noted that the engagement of the snap-fit ​​groove 1701 and the insert bracket 12 enables the rapid positioning of the brick blank forming mold 7, while the fixing bolt 22 enhances the connection stability and facilitates the replacement of brick blank forming molds 7 of different sizes according to the brick blank specifications, thereby improving the versatility of the device.

[0032] In this embodiment, the ejection assembly includes a base frame 9, a second electric push rod 10, a lifting plate 8, and push blocks 11. The base frame 9 is installed at the bottom of the support plate 6 and at the bottom of the two sets of through slots 18. The second electric push rod 10 is installed at the bottom of the base frame 9. The telescopic shaft of the second electric push rod 10 passes through the base frame 9 and is connected to the lifting plate 8. Multiple push blocks 11 are installed on the upper surface of the lifting plate 8 and extend into multiple through slots 18 that are adapted to it. When not in operation, the upper end of the push block 11 is flush with the upper end of the support plate 6.

[0033] It should be noted that after the brick blank is extruded and formed, the second electric push rod 10 drives the lifting plate 8 to rise, and the push block 11 passes through the through groove 18 to push the brick blank out of the forming mold. There is no need for manual removal of bricks, which reduces the intensity of operation and shortens the operation time.

[0034] Example 2 like Figure 2-5As shown, based on Embodiment 1, further limitations are made, including a signal receiver 19, a groove 20, and an infrared transmitter 21. There are two grooves 20, which are symmetrically opened on the upper end of the support plate 6. The signal receiver 19 is installed inside the groove 20, with the receiving end of the signal receiver 19 facing upward. The infrared transmitter 21 is installed at the bottom of one of the connecting rods 13, and the positions of the infrared transmitter 21 and the signal receiver 19 are adapted to each other. The controller 1 is electrically connected to the signal receiver 19 and the infrared transmitter 21 respectively.

[0035] It should be noted that when the infrared transmitter 21 moves to align with the signal receiver 19, the signal receiver 19 receives the signal and transmits it to the controller 1. The controller 1 then controls the moving mechanism to stop running, thereby achieving precise positioning of the brick forming mold 7 and ensuring that it corresponds to the positions of the pressing component and the ejection component.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
