Description

Technical Field

[0001] This utility model relates to the field of brick blank mold technology, specifically a vibration forming mold for refractory brick blanks. Background Technology

[0002] Refractory brick blank forming molds shape premixed refractory material blanks according to requirements, determining the final product's shape, size, and internal structure. The mold structure includes a mold shell, inner mold, tie rods and fixing devices, as well as venting holes and a lubrication system. The mold shell is made of steel plate or cast iron, providing sufficient strength and stability; the inner mold ensures accurate replication of the blank's shape and internal structure and is typically made of wear-resistant steel. Tie rods and fixing devices are used to adjust the mold's positional relationship, ensuring forming accuracy and stability; venting holes expel gases generated during the forming process, preventing internal defects. The forming process encompasses steps such as mold preparation, blank filling, forming treatment, mold opening, and subsequent processing. Through these steps, the mold ensures that the refractory brick product maintains high quality and consistency throughout the production process.

[0003] For example, the refractory brick forming mold disclosed in the authorization announcement number CN219968297U includes a mold box and an ejection mechanism set at the bottom of the mold box and a limiting mechanism located on the inner wall of the mold box. The inner wall of the mold box is fixedly connected with multiple high-temperature resistant partitions. The limiting mechanism consists of an electric push rod, a sliding plate and a first heat insulation plate. Through the setting of the ejection mechanism, when demolding is required, the hydraulic rod drives the lifting plate to move and the electric push rod pulls the sliding plate to move, so that the refractory bricks inside the mold box can be quickly separated from the inner wall of the mold box and the refractory bricks can be easily removed. However, when the above technical solution fills the brick blank chamber in the mold box with refractory brick raw materials, it relies on vibrators to vibrate and flatten the refractory brick raw materials in the brick blank chamber and expel air. The vibrators are set in the brick blank chamber, and each brick blank chamber needs to be equipped with a vibrator. Therefore, a large number of vibration equipment is required on the production line, which increases the number of equipment and energy consumption costs. Moreover, arranging vibrators in the mold box will also hinder the subsequent sintering of brick materials. Utility Model Content

[0004] The purpose of this utility model is to provide a refractory brick blank vibration molding mold, in which a track drive unit and a double-link reciprocating pushing structure drive the brick blank mold, which is slidably mounted on an inverted U-shaped support, to reciprocate and vibrate, so as to achieve the purpose of vibrating the brick blank mold and the internal brick material, expelling air, flattening the brick material and the brick blank mold, and removing them from the device and sending them into the sintering furnace, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a refractory brick blank vibration molding mold, comprising a frame and a partition fixed inside the frame. An inverted U-shaped support is fixed on the outer wall of one side of the frame, and a connecting arm is horizontally slidably installed inside the inverted U-shaped support. The top of the connecting arm is detachably mounted with a brick blank mold via a column groove docking structure. A main shaft is rotatably mounted inside the partition. Two symmetrical right-angle seats are fixed at the bottom of the inverted U-shaped support. A U-shaped arm is slidably installed on the outer wall of the right-angle seats away from the frame. The top of the U-shaped arm is fixedly connected to the bottom of the connecting arm. A double-link reciprocating pushing structure for driving the U-shaped arm to vibrate and slide horizontally is installed at the bottom of the main shaft. A track drive unit for driving the main shaft to rotate is installed at the top of the partition. A control panel electrically connected to the input end of the track drive unit is installed on one side of the surface of the inverted U-shaped support.

[0006] Preferably, the top of the inverted U-shaped support is provided with a straight hollow groove that runs through it completely, and the connecting arm is slidably installed inside the straight hollow groove.

[0007] Preferably, the column groove docking structure consists of a circular docking groove at the bottom of the brick blank mold and a columnar protrusion fixed to the top of the connecting arm, with the columnar protrusion and the circular docking groove interlocking with each other.

[0008] Preferably, rectangular guide rails are fixed on both sides of the top of the inverted U-shaped support, and a rectangular rib groove is provided at the bottom of the brick mold for sliding cooperation with the rectangular guide rails.

[0009] Preferably, the double-link reciprocating pushing structure includes a short link fixed to the bottom end of the main shaft, a long link hinged to one end of the short link, and a guide post slidably installed inside the right-angle seat. A vertical rod is fixed to the bottom end of the guide post, and the bottom end of the vertical rod and one end of the long link are hinged to each other.

[0010] Preferably, the track drive unit includes a stepper motor mounted on the top of the partition plate, and a track transmission structure mounted on the output end of the stepper motor for driving the main shaft to rotate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The refractory brick blank vibration molding mold is equipped with a double-link reciprocating pushing structure and a connecting arm and other structures that cooperate with each other. Through reciprocating translational vibration, the brick material in the mold is filled and leveled more evenly. In addition, the mold adopts a crawler drive unit and a double-link reciprocating pushing structure, which can be used to uniformly install the brick blank mold on an inverted U-shaped support. The entire mold can be controlled to reciprocate through a single crawler drive unit. This not only reduces the number of vibration devices required, but also reduces the energy consumption cost in the later stage of use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5 An embodiment of this utility model provides a refractory brick blank vibration molding mold, including a frame 1 and a partition 101 fixed inside the frame 1. An inverted U-shaped support 2 is fixed on the outer wall of one side of the frame 1, and a connecting arm 10 is horizontally slidably installed inside the inverted U-shaped support 2. The top of the connecting arm 10 is detachably installed with a brick blank mold 5 through a column groove docking structure. A main shaft 7 is rotatably installed inside the partition 101. Two symmetrical right-angle seats 6 are fixed at the bottom of the inverted U-shaped support 2. A U-shaped arm 9 is slidably installed on the outer wall of the right-angle seat 6 away from the frame 1. The top of the U-shaped arm 9 is fixedly connected to the bottom of the connecting arm 10. A double-link reciprocating pushing structure 8 for driving the U-shaped arm 9 to vibrate and slide horizontally is installed at the bottom of the main shaft 7. A track drive unit 4 for driving the main shaft 7 to rotate is installed at the top of the partition 101. A control panel 3 electrically connected to the input end of the track drive unit 4 is installed on one side of the surface of the inverted U-shaped support 2.

[0020] The column-groove docking structure consists of a circular docking groove 502 at the bottom of the brick blank mold 5 and a columnar protrusion fixed to the top of the connecting arm 10. The columnar protrusion and the circular docking groove 502 interlock with each other. After the brick blank mold 5 is vibrated and flattened, the workers manually lift the brick blank mold 5 so that the circular docking groove 502 at the bottom of the brick blank mold 5 no longer docks with the columnar protrusion at the top of the connecting arm 10. The processed brick blank mold 5 is then sent into the sintering furnace. At this time, the brick blank mold 5 itself no longer carries vibrators or other electric equipment, ensuring that the brick blank mold 5 and the brick blank raw materials inside are sintered and formed.

[0021] The top of the inverted U-shaped support 2 is provided with a straight hollow groove 202 that runs through it completely. The connecting arm 10 is slidably installed inside the straight hollow groove 202. Rectangular guide rails 201 are fixed on both sides of the top of the inverted U-shaped support 2. The bottom of the brick mold 5 is provided with a rectangular rib groove 501 for sliding cooperation with the rectangular guide rail 201.

[0022] During the horizontal sliding process, the sliding stability of the brick blank mold 5 is improved by the rectangular rib groove 501 and the rectangular guide rail 201.

[0023] The double-link reciprocating push structure 8 includes a short link fixed to the bottom of the main shaft 7, a long link hinged to one end of the short link, and a guide post 11 slidably installed inside the right-angle seat 6. The bottom end of the guide post 11 is fixed with a vertical rod 12. During the sliding process of the guide post 11, the right-angle seat 6 plays the role of assisting in guiding the guide post 11 and the U-shaped arm 9 to slide, so that their operation is more stable.

[0024] The bottom end of the upright 12 and one end of the long connecting rod are hinged to each other. One end of the guide post 11 extends to the outside of the right-angle seat 6 and is fixedly connected to one side of the outer wall of the U-shaped arm 9. The track drive unit 4 includes a stepper motor installed on the top of the partition 101, and a track transmission structure installed at the output end of the stepper motor for driving the main shaft 7 to rotate.

[0025] The main shaft 7 drives the short connecting rod in the double connecting rod reciprocating push structure 8 to rotate. The end of the short connecting rod drives the guide column 11, U-shaped arm 9 and connecting arm 10 to reciprocate horizontally through the long connecting rod and the upright rod 12, thereby ultimately realizing the vibration function of the brick mold 5. This ensures that the raw materials in each blank chamber are evenly distributed during the filling process, effectively avoiding the situation of insufficient filling or over-compaction that may occur with traditional vibrators.

[0026] In this embodiment, the operator first pours brick blank raw materials into each chamber of the brick blank mold 5, and then installs the brick blank mold 5 containing the raw materials onto the top of the connecting arm 10 via a column groove docking structure. At this time, the bottom end of the brick blank mold 5 is slidably connected to the top end of the inverted U-shaped support platform 2. The operator then activates the track drive unit 4 via the control panel 3, which transmits the rotational power of the track drive unit 4 to the main shaft 7 and the double-link reciprocating push structure 8. This allows the rotational motion of the main shaft 7 to be converted into the horizontal motion of the U-shaped arm 9 and the connecting arm 10 via the double-link reciprocating push structure 8. The reciprocating motion enables the horizontal vibration function of the brick blank mold 5. During the vibration process, the brick blank raw material can be actively flattened and the air in the brick blank raw material can be actively discharged. In this way, the brick material in the mold is more evenly filled and flattened through reciprocating translational vibration. The mold adopts the structure of track drive unit 4 and double connecting rod reciprocating pushing structure 8. The brick blank mold 5 can be uniformly installed on the inverted U-shaped support platform 2. The entire mold can be reciprocated and vibrated by a single track drive unit 4. This not only reduces the number of vibration devices, but also reduces the energy consumption cost in the later use.
