Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam brick mold technology, specifically a foam brick forming mold. Background Technology
[0002] Foam bricks, with their numerous advantages such as lightweight, heat insulation, sound insulation, earthquake resistance, and environmental friendliness, are widely used in building walls, insulation filling, and other engineering fields. In the industrial production process of foam bricks, the molding mold is the core key equipment that determines the molding precision, product quality, and production efficiency of foam bricks. Its operational stability and degree of automation directly affect the production efficiency of the entire production line.
[0003] Currently, existing foam brick molding dies still have significant technical shortcomings in practical production applications. Most mainstream molding equipment adopts a split-type operation mode, with feeding and pressing processes operating independently, lacking an integrated, interconnected structure. During the foam blank conveying and mold pressing processes, manual assistance is largely required for alignment. This involves manually moving and calibrating multiple foam blanks one by one under the mold's pressing station to ensure a proper match between the blank and the mold cavity before initiating the pressing operation to complete the molding process.
[0004] This traditional operating method has many drawbacks: First, the accuracy of manual alignment is limited. Affected by the operator's experience, focus, and fatigue, problems such as foam blank displacement, misalignment, and deviation are very likely to occur. This results in large dimensional deviations and uneven molding of the foam brick blanks after the mold is pressed down, which easily produces defective products and significantly reduces the product molding quality and pass rate. Second, the operation process of manually aiming, aligning, and placing the blanks is cumbersome and involves many manual interventions, which greatly increases the labor intensity and severely restricts the production efficiency of foam brick molding, making it unsuitable for the high-efficiency production needs of large-scale, assembly line production. Third, continuous manual intervention in the operation process not only increases the company's labor production costs, but also easily leads to equipment jamming, blank scrap, or even equipment damage due to human operation errors, increasing the production failure rate and equipment maintenance costs.
[0005] In summary, existing foam brick molding dies suffer from low automation, reliance on manual alignment, poor molding accuracy, low production efficiency, and high production costs, making it difficult to meet the demands of modern foam brick production for high efficiency, high precision, and automation. Therefore, there is an urgent need to develop a foam brick molding die that features automatic feeding, precise alignment, and eliminates the need for manual aiming, in order to address the technical limitations of existing technologies. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a foam brick molding mold that can effectively solve the aforementioned technical problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A foam brick molding die includes a lower mold frame and an upper pressure head. The lower mold frame has several molding cavities below it. Each molding cavity has an upper sealing plate at its upper end. The front and rear side walls of each molding cavity have vertically extending guide ribs below the upper sealing plate. The upper sealing plate has guide rods extending into the molding cavities. The left and right side walls of the upper sealing plate have spaced-apart first positioning grooves and first positioning blocks. The upper end of each guide rod is embedded in the upper sealing plate, and the lower end of each guide rod has a guide cone surface. Two guide rods are provided, symmetrically arranged front and rear.
[0009] Furthermore, the first positioning groove on the left side wall of the upper sealing plate is correspondingly located on the side of the first positioning block on the right side wall of the upper sealing plate.
[0010] Furthermore, the upper end of the molding cavity is also provided with connecting rods, which are symmetrically arranged on the left and right sides of the upper sealing plate, and the lower end of the connecting rods is provided with several mold cores.
[0011] Furthermore, connecting ears are provided on both sides of the lower mold frame.
[0012] Furthermore, the upper pressure head includes an upper template, and the lower end of the upper template is provided with a first support plate and a second support plate. The first support plate and the second support plate are symmetrically arranged in the molding cavity. The first support plate extends between the upper sealing plate and the connecting rod, and the second support plate extends between the connecting rod and the side wall of the molding cavity.
[0013] Furthermore, the lower end of the first support plate is provided with a first pressure plate, the lower end of the second support plate is provided with a second pressure plate, and the side wall of the first pressure plate is provided with a second positioning block and a second positioning groove spaced apart. The second positioning block is correspondingly located on the side of the first positioning groove, and the second positioning groove is correspondingly located on the side of the first positioning block.
[0014] Furthermore, the sidewalls of the first and second support plates are provided with through holes.
[0015] Furthermore, a limiting post is provided at the lower end of the upper template.
[0016] This utility model provides a foam brick molding mold. It has the following beneficial effects:
[0017] First, this invention achieves fully automated and precise alignment between the mold and the foam blank, completely eliminating manual aiming and significantly improving molding accuracy. This invention utilizes a dual-guide positioning structure formed by vertical guide ribs in the molding cavity and guide rods with guide cone surfaces on the upper sealing plate. During mold pressing, the guide ribs limit and guide the foam blank, while the guide rods precisely engage with the holes in the foam blank. Combined with the matching positioning grooves and blocks between the upper sealing plate and the upper pressure head, multi-dimensional precise positioning is achieved. This effectively eliminates problems such as blank offset, misalignment, and deviation caused by traditional manual alignment, ensuring uniform molding dimensions and uniform blank formation for each foam brick, greatly reducing product defect rates, and significantly improving the molding quality and product qualification rate of foam bricks.
[0018] Secondly, it reduces manual intervention, lowers labor intensity and production costs, and is compatible with automated production lines. This mold can work with a feeding mechanism to complete automated feeding and precise pressing molding operations, eliminating the need for manual handling, calibration, and aiming of foam blanks. This simplifies the molding process and significantly reduces manual operations. It effectively reduces the labor intensity of operators, saves on labor costs, and avoids problems such as blank scrap, equipment jamming, and equipment damage caused by human error. This reduces equipment failure rates and subsequent maintenance costs, perfectly meeting the needs of modern, large-scale, automated production lines and significantly improving production efficiency.
[0019] Third, the mold structure boasts high compatibility, strong operational stability, and superior molding functionality. This utility model employs a split symmetrical support plate and pressure plate structure. The first and second support plates are partitioned to fit within the molding cavity, and with the help of limiting posts, the downward stroke is precisely limited, ensuring uniform downward force and stable operation, avoiding molding defects caused by downward displacement. Simultaneously, the through holes on the side walls of the support plates can accommodate the ventilation and pressure relief requirements of foam brick molding. Combined with the mold core structure at the lower end of the connecting rod, the through holes and molding grooves of the foam brick can be integrally molded in one step, eliminating the need for secondary processing and simplifying the production process. Furthermore, adjacent mold components can be precisely spliced and fitted through positioning blocks and positioning grooves, resulting in stronger overall mold structure stability, adaptability, and a longer service life.
