Description

Technical Field

[0001] The invention relates to the technical field, in particular to a hollow brick forming device capable of ensuring the integrity of edges and corners. Background Art

[0002] Hollow bricks are a lightweight wall material widely used in the construction field. They have the advantages of light weight, good thermal insulation, and convenient construction. However, in the production process of hollow bricks, problems such as poor fluidity of raw materials and uneven filling have always been important factors restricting product quality. Traditional hollow brick forming equipment usually adopts a one-time filling method for raw materials, but due to the poor fluidity of the raw materials, it is easy to cause inaccurate filling amount, which in turn causes problems such as uneven density and incomplete edges and corners of the hollow bricks after forming. These problems not only affect the appearance quality of hollow bricks, but also reduce their mechanical properties and durability, making it difficult to meet the demand for high-quality wall materials in modern buildings.

[0003] Existing hollow brick forming equipment often cannot effectively control the distribution of raw materials when filling them, especially in the corners, where the porosity is too high or the filling is insufficient. In addition, due to the poor fluidity of the raw materials, the equipment is prone to waste of raw materials during the filling process, further increasing production costs. In order to solve these problems, some equipment attempts to improve the uniformity of raw material distribution by vibration or pressurization, but these methods often have limited effects and cannot fundamentally solve the problem of uneven filling caused by poor raw material fluidity.

[0004] Therefore, there is an urgent need for a molding device that can accurately control the amount of raw materials added, improve the uniformity of raw material distribution, and effectively ensure the integrity of the edges and corners of hollow bricks. Through technological innovation, solving the defects of existing equipment in the process of raw material filling and molding, and improving the overall quality and production efficiency of hollow bricks have become an important research direction in the current field of hollow brick production. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a hollow brick forming device that ensures the integrity of edges and corners, thereby solving the above-mentioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a hollow brick forming device that ensures the integrity of edge corners, comprising an upper mold driven by a lifting mechanism, a lower mold assembly driven to rotate reciprocatingly by an annular chain drive belt, and a filling mechanism arranged on the side of the annular chain drive belt for filling the lower mold assembly with raw materials, the lower mold assembly comprising a mold cavity fixed to the side of the annular chain drive belt transmission member and a bottom mold driven to slide at the bottom of the mold cavity by a cylinder, a filling groove is provided on one side of the upper mold, one side of the filling groove is connected to the filling mechanism through a feeding pipe, an empty groove adapted to the filling groove is provided at the bottom of the upper mold inner cavity, a push rod driven by a first cylinder is slidably connected to the top of the filling groove, a first sealing plate driven by a driving mechanism and a blocking plate driven by a second cylinder are respectively provided on the front and rear sides of the empty groove, the first sealing plate and the blocking plate are both adapted to the inner cavity of the empty groove, the bottoms of the first sealing plate and the blocking plate are both embedded in the inner cavity of the mold cavity, and the inner cavity of the mold cavity is provided with a sealing plate adapted to the dividing The embedded groove is specially adapted to the first sealing plate and the blocking plate. When in use, a certain amount of raw materials is first added to the mold cavity of the lower mold assembly through the filling mechanism, and then the lower mold assembly is transported through the ring chain drive belt. During transportation, the vibration motor is continuously vibrated to ensure that the corner porosity is ≤3%, and then it is transported to the bottom of the upper mold for molding. The upper mold descends and squeezes inside the lower mold. At this time, supplementary materials are added to the filling groove through the feed pipe, and then the ejector rod is driven downward by the first cylinder to squeeze the material into the empty groove, and then enters the mold cavity along the empty groove for secondary filling of raw materials. After filling until the ejector rod pressure feedback reaches a certain value, the first sealing plate and the blocking plate are started at this time. The first sealing plate moves to the inside of the empty groove to seal the bottom of the upper mold to form a complete surface, and the remaining raw materials in the empty groove are pushed out and recovered through the recovery bucket, which effectively solves the problem that the hollow brick raw materials cannot be accurately and quantitatively filled due to poor fluidity, resulting in large quality deviations and uneven density of the formed hollow bricks.

[0007] As a further solution of the present invention: it also includes a recovery bucket arranged between the upper mold and the lower mold assembly, and the recovery bucket is arranged on the side of the empty slot. The excess raw material in the empty slot is ejected by the first sealing plate and falls into the recovery bucket for storage, and then added to the filling mechanism for recycling.

[0008] As a further solution of the present invention: multiple lower mold assemblies are provided, and a vibration motor is provided on the side. The vibration motor drives the lower mold assembly to vibrate, and the raw materials in the mold cavity are shaken evenly to make the quality more uniform.

[0009] As a further solution of the present invention: the first sealing plate, the empty groove and the blocking plate are on the same horizontal line.

[0010] As a further solution of the present invention: the bottom of the upper mold is movably connected with a push plate driven by a cylinder through an adapter groove. During demolding, after the bottom mold and the mold cavity are separated, the cylinder drives the push plate to descend to push the internal hollow brick body from the mold cavity downward and fall above the bottom mold for demolding. The demolding can be completed to prevent edge collapse around the edges.

[0011] As a further solution of the present invention: the inner wall of the mold cavity is covered with a wear-resistant ceramic coating to reduce the friction coefficient during demoulding.

[0012] As a further solution of the present invention: the four corners of the mold cavity are provided with a micro-texture structure with a depth of 20-50 μm to enhance the anchoring effect of the material.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention accurately controls the amount of raw material added, improves the uniformity of raw material distribution, and effectively ensures the integrity of the edges and corners of hollow bricks. The raw material is added for the second time. After the pressure feedback of the ejector rod reaches a certain value, the first sealing plate and the blocking plate are started. The first sealing plate moves to the inside of the empty groove to block the bottom of the upper mold to form a complete surface, and the remaining raw material in the empty groove is pushed out and recovered through a recovery bucket, which effectively solves the problem that the raw material of the hollow brick has poor fluidity and cannot be accurately and quantitatively added, resulting in large quality deviation and uneven density of the formed hollow bricks.

The demoulding can be completed to prevent the edges from collapsing. BRIEF DESCRIPTION OF THE DRAWINGS
