Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a molding die for refractory bricks. Background Technology

[0002] As a key lining material for high-temperature industrial kilns and metallurgical equipment, the molding quality of refractory bricks directly determines the structural strength, high-temperature resistance, and service life of the product. Molding molds are the core equipment in refractory brick production. By applying pressure to refractory raw materials (such as bauxite, magnesia, clay, etc.), the loose materials are densified and formed into specific shapes (such as standard bricks, wedge-shaped bricks, and irregular-shaped bricks).

[0003] Existing technology discloses a batch forming mold for refractory bricks, application number 202420150817.6, comprising a main blank body with several uniformly formed finished product cavities, and a partition plate for dividing the finished product cavities into two independent injection cavities; a connecting cavity connected to each injection cavity is provided at the lower part of the main blank body, and a removable support plate is provided in the connecting cavity, the support plate and the injection cavity forming an injection groove for making refractory bricks. This utility model can form 12 refractory bricks at one time, the bottom of the refractory bricks is flat and smooth without rough edges, and after forming, the main blank body can be flipped upside down, and the support plate can be removed for quick demolding of the refractory bricks. However, the existing technology still has the problem of fixed injection cavity depth, which cannot be adjusted according to the production needs of refractory bricks of different thicknesses, requiring the replacement of different molds, increasing production costs and mold change time. To address this, we propose a refractory brick forming mold to solve the above problems. Utility Model Content

[0004] To address the shortcomings mentioned above, this utility model provides a refractory brick forming mold that allows the injection cavity depth to be adjusted by raising and lowering an adjusting block, adapting to the production of refractory bricks of different thicknesses; and relies on the adjusting block and mold body lifting structure driven by an electric push rod to achieve automatic demolding without flipping.

[0005] To solve the above problems, the technical solution provided by this utility model is as follows:

[0006] A refractory brick forming mold includes a processing table and a mold body. The mold body has multiple injection cavities, with a partition between the front and rear injection cavities. A vibrating column is installed within the partition. A slot is formed in the middle of the processing table, and a push plate is installed within the slot. An adjusting block is fixedly installed at the upper end of the push plate, and the adjusting block is located inside the injection cavity, slidingly connected to the cavity. Metal ear plates are fixedly connected to both sides of the push plate. Mounting slots are formed on both sides of the slot, and an electric push rod is installed within each mounting slot. The output end of the electric push rod is fixedly connected to the lower surface of the metal ear plate. Metal ear plates are fixedly installed on the left and right sides of the outer wall of the mold body. Mounting plates are fixedly welded to the left and right sides of the outer wall of the processing table, and electric push rods are installed at the upper ends of the mounting plates. The output end of the electric push rods is fixedly connected to the metal ear plates.

[0007] Furthermore, a plug rod is fixedly installed on the upper end of the push plate, the plug rod is symmetrically arranged on both sides of the adjusting block, and a slot matching the plug rod is opened at the lower end of the mold body.

[0008] Furthermore, the vibrating column is an electromagnetic vibrating column, and three vibrating columns are evenly arranged along the length direction of each of the partitions.

[0009] Furthermore, the inner wall of the injection cavity is coated with a polytetrafluoroethylene non-stick coating.

[0010] Furthermore, both the electric actuator one and the electric actuator two are servo electric actuators.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The electric push rod drives the push plate to move the adjusting block up and down in the injection cavity, which can flexibly adjust the depth of the injection cavity. It can adapt to the production needs of refractory bricks of different thicknesses without changing the mold, greatly improving the versatility of the mold and the flexibility of production.

[0013] 2. During demolding, the electric push rod 2 drives the mold body to lift upwards, while the electric push rod 1 pushes the adjusting block upwards to form the refractory brick. Through the coordinated action of "mold lifting + adjusting block pushing", automatic demolding without flipping is achieved, avoiding product damage caused by traditional flipping demolding, and improving demolding efficiency and yield.

[0014] 3. The electromagnetic vibration column inside the partition plate can make the raw material in the injection cavity evenly distributed. The polytetrafluoroethylene non-stick coating on the inner wall of the injection cavity reduces the adhesion of raw materials. Combined with the precise control of the servo electric push rod, it not only ensures the stability of the refractory brick molding quality, but also reduces the mold maintenance cost and extends the service life.

[0015] In summary, this type of refractory brick molding die has wide applicability, solving the problem mentioned in the background art that the existing technology still has a fixed injection cavity depth, which cannot be adjusted according to the production needs of refractory bricks of different thicknesses, requiring the replacement of different molds, increasing production costs and mold change time.

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples, but the examples given are not intended to limit the present utility model.

[0022] like Figures 1-3 As shown, the embodiment of this utility model includes a processing table 1 and a mold body 2. The processing table 1 provides basic support for the mold. The mold body 2 has an injection cavity 201 as a refractory brick forming space. The lifting and adjusting component adjusts the volume of the injection cavity to adapt to different specifications of blanks. The demolding drive component realizes the separation of the mold and the blank. The vibration densification component increases the density of the blank, and the whole forms an integrated molding system of "forming-densification-demolding".

[0023] The processing table 1 is made of high-strength cast iron, which has good rigidity and stability, and avoids deformation due to vibration or pressure during the molding process. A slot 101 is provided in the middle of the processing table 1 to accommodate the push plate 3 and the adjusting block 4; mounting slots 102 are symmetrically provided on both sides of the slot 101 to provide installation space for the electric push rod 6 and ensure that the drive components are compactly arranged.

[0024] The mold body 2 is placed on the upper end of the processing table 1, and has multiple injection cavities 201 inside (the number can be set according to production needs, such as 2-6). The shape and size of the injection cavities 201 match the design specifications of the refractory bricks (such as rectangular or wedge-shaped). A partition 12 is provided between the front and rear injection cavities 201. The partition 12 is integrally formed with the mold body 2 and is used to separate the molding spaces to ensure that the blank is formed in a regular manner.

[0025] The inner wall of the injection cavity 201 is coated with a polytetrafluoroethylene non-stick coating. This coating has a smooth and wear-resistant surface, which can significantly reduce the friction between the refractory brick raw material and the cavity wall, prevent the raw material from sticking to the cavity wall and causing demolding difficulties, and at the same time reduce the frequency of cavity wall cleaning and improve production efficiency.

[0026] The lifting and adjusting assembly is used to adjust the effective volume of the injection chamber 201 to accommodate refractory brick blanks of different thicknesses, and also assists in demolding. The specific structure is as follows:

[0027] A push plate 3 is provided in the slot 101. An adjustment block 4 (the size of which matches the inner cavity of the injection cavity 201) is fixedly provided on the upper end of the push plate 3. The adjustment block 4 is embedded in the injection cavity 201 and is slidably connected to the inner wall of the injection cavity 201 to form a movable bottom mold that can be raised and lowered.

[0028] Metal ear plates 5 are fixedly connected to both sides of the push plate 3. An electric push rod 6 (servo electric push rod) is installed in the mounting groove 102. The output end of the electric push rod 6 is fixedly connected to the lower surface of the metal ear plates 5. The servo electric push rod has precise stroke control capability (accuracy up to ±0.1mm). By adjusting the lifting height of the push plate 3, the volume of the injection chamber 201 can be precisely controlled to adapt to the production needs of refractory bricks of different thicknesses.

[0029] A pusher plate 3 is fixedly mounted with a rod 10, which is symmetrically arranged on both sides of the adjusting block 4. The mold body 2 has a slot 202 at the lower end that matches the rod 10. When the adjusting block 4 is raised or lowered or the mold body 2 is moved, the rod 10 is always embedded in the slot 202, which provides guidance for the relative movement of the adjusting block 4 and the mold body 2, avoids the offset of the adjusting block 4 and the resulting deviation in the blank forming size, and enhances the overall structural stability of the mold.

[0030] The demolding drive assembly is used to drive the mold body 2 to rise and fall, thereby separating the mold from the formed blank. The specific structure is as follows:

[0031] Metal ear plates 7 are fixedly installed on the left and right sides of the outer wall of the mold body 2. Mounting plates 9 are fixedly welded on the left and right sides of the outer wall of the processing table 1. Electric push rods 8 (servo electric push rods) are installed on the upper end of the mounting plates 9. The output end of the electric push rods 8 is fixedly connected to the metal ear plates 7.

[0032] After the refractory brick blank is formed in the injection cavity 201, the electric push rod 28 extends, driving the mold body 2 upward. At this time, the adjusting block 4 remains stationary under the locking action of the electric push rod 6, and the blank remains in its original position with the adjusting block 4. The mold body 2 gradually separates from the blank, completing the demolding. After demolding, the electric push rod 28 retracts and resets, waiting for the next forming. The stable driving force of the servo electric push rod can avoid uneven force on the blank during demolding, which may cause damage and improve the blank qualification rate.

[0033] The vibration densification component is used to eliminate voids in the raw material within the injection chamber 201, thereby increasing the density and strength of the refractory brick blank. Its specific structure is as follows:

[0034] Vibrating columns 11 are installed inside the partition 12. The vibrating columns 11 are electromagnetic vibrating columns, which have the characteristics of adjustable vibration frequency and stable amplitude. Three vibrating columns 11 are evenly arranged along the length of each partition 12 to ensure that the vibration energy is evenly transmitted to the raw material in each injection chamber 201.

[0035] After the refractory brick raw material is injected into the injection chamber 201, the vibrating column 11 is activated. High-frequency vibration rearranges the raw material particles, fills the gaps between the particles, and reduces residual air bubbles. At the same time, vibration promotes the adhesion of the raw material to the chamber wall, ensuring the integrity of the green body's edges and corners. After vibration is completed, the vibrating column 11 is turned off, and subsequent compaction or static molding is carried out, which significantly enhances the structural strength and high-temperature resistance of the finished refractory brick.

[0036] All electrical components mentioned in the text are electrically connected to an external controller and power supply, and the controller can be a conventional known device such as a computer that provides control.
