Artificial stone material press molding apparatus

Abstract

This utility model belongs to the field of artificial stone slab preparation technology, especially artificial stone slab material pressing and molding equipment. Addressing the problem that existing single pressing forces are insufficient to completely eliminate these gaps, resulting in uneven density and unstable quality of the pressed artificial stone slab material, the following solution is proposed: A base is included, with a mold fixed inside the base to hold the artificial stone slab material. Four limiting rods are fixed to the top of the base, and a common top plate is fixed to the top of the four limiting rods. A common lifting plate slides on the surface of the four limiting rods. An inverted U-shaped frame is fixed to the bottom of the lifting plate, and a secondary pressing plate is fixed to the bottom of the inverted U-shaped frame. A main pressing plate is located at the bottom of the secondary pressing plate for pressing the artificial stone slab material in the mold. An air hammer, driven by an air compressor, strikes downwards, causing the main pressing plate to perform secondary hammering and compaction. This hammering compaction method effectively eliminates air gaps inside the artificial stone slab material, resulting in a more uniform particle distribution.

Description

Technical Field

[0001] This utility model relates to the field of artificial stone slab preparation technology, and in particular to equipment for pressing and molding artificial stone slab materials. Background Technology

[0002] In the production process of artificial stone slabs, pressing and molding is one of the key steps. Traditional artificial stone slab pressing and molding equipment usually relies on a single pressing force to press the artificial stone slabs in the mold, which has certain limitations.

[0003] Because air gaps or uneven particle distribution may exist within artificial stone slabs during the pressing process, a single pressing force is insufficient to completely eliminate these gaps. This results in uneven density and unstable quality in the pressed artificial stone slabs, making them prone to cracking and insufficient strength. Furthermore, traditional pressing equipment often requires manual assistance during discharge, leading to low efficiency and increased production costs. Therefore, there is a need for an artificial stone slab pressing and molding equipment that can improve pressing efficiency and achieve automatic discharge. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where a single pressing force is insufficient to completely eliminate these gaps, resulting in uneven density and unstable quality of the pressed artificial stone slabs. Therefore, this invention proposes an artificial stone slab pressing and molding equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Artificial stone slab pressing and molding equipment includes a base, a mold fixedly installed inside the base for holding artificial stone slab material, four limiting rods fixed to the top of the base, a common top plate fixed to the top of the four limiting rods, a common lifting plate sliding on the surface of the four limiting rods, an inverted U-shaped frame fixed to the bottom of the lifting plate, a secondary pressing plate fixed to the bottom of the inverted U-shaped frame, a main pressing plate for pressing the artificial stone slab material in the mold at the bottom of the secondary pressing plate, and a set of pressing components on the top plate. In order to increase the pressing effect on the artificial stone slab material in the mold, a set of hammering components is provided in the secondary pressing plate. The hammering components are used to compact the artificial stone slab material by hammering the main pressing plate. The bottom of the mold is equipped with a set of lifting components, which are used to drive the pressed and shaped artificial stone slab material to be discharged.

[0006] In one possible design, the pressing assembly includes a pressing cylinder at the top of the top plate, the output end of the pressing cylinder moving downward through the top plate, and the lifting plate being fixed to the output end of the pressing cylinder.

[0007] In one possible design, the lifting plate is fixedly connected to the output end of the pressing cylinder via a connecting flange.

[0008] In one possible design, the hammering assembly includes a first groove formed in a secondary pressure plate, two air hammers fixed in the secondary pressure plate, a slide plate slidably disposed in the first groove, two connecting posts fixed at the bottom end of the slide plate, both connecting posts moving downward through the bottom end of the secondary pressure plate and extending downward, and the main pressure plate fixed to the bottom end of the two connecting posts. Both air hammers are connected to the air compressor. When the main pressing plate enters the mold, it is held up by the artificial stone material. The secondary pressing plate continues to move, causing the slide plate to slide in the first groove. A buffer gap is formed between the slide plate and the first groove. At this time, the air compressor is started to provide compressed air to drive the two air hammers to hammer downwards, which can drive the main pressing plate to hammer downwards and effectively compact the artificial stone material.

[0009] In one possible design, a rubber pad is fixed to the top of the slide plate to reduce wear on the hammer, anvil, or mold, thereby reducing maintenance costs.

[0010] In one possible design, the lifting assembly includes a receiving groove formed within the mold, a lifting plate provided within the receiving groove, the lifting plate being used to lift the artificial stone slab material, and a lifting hydraulic cylinder fixed to the bottom end of the mold, the output end of the lifting hydraulic cylinder being movably inserted into the receiving groove and fixedly connected to the lifting plate.

[0011] In this application, by setting up a hammering component, after the main pressing plate enters the mold and initially presses the artificial stone slab, an air hammer, driven by an air compressor, hammers downwards, causing the main pressing plate to perform a secondary hammering compaction. This hammering compaction method can effectively eliminate air gaps inside the artificial stone slab, making the particle distribution more uniform, thereby improving the density and quality of the artificial stone slab and reducing the occurrence of quality problems such as cracking. Beneficial effects: In this utility model, the rubber pad in the artificial stone slab pressing and molding equipment plays a buffering role when the air hammer strikes, which can reduce the wear of the hammer head, anvil or mold, extend the service life of the equipment and reduce maintenance costs. In this invention, the artificial stone slab pressing and molding equipment features a lifting component that enables automatic discharge of the pressed and molded artificial stone slab material without manual assistance, thereby improving production efficiency and reducing labor intensity and production costs.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In one embodiment: Refer to Figures 1-3 This is an artificial stone slab pressing and molding equipment, used in the field of artificial stone slab preparation technology. It includes a base 1 as the basic support structure, inside which a mold 2 is fixed. The mold 2 holds the artificial stone slab material, providing space for pressing and molding. Four limiting rods 4 are fixed to the top of the base 1, arranged in a rectangular shape, and their tops are fixed to the same top plate 5, forming a stable frame structure. A common lifting plate 6 is slidably mounted on the surface of the four limiting rods 4, allowing the lifting plate 6 to slide up and down under the guidance of the limiting rods 4. A U-shaped frame 8 is fixed to the bottom of the lifting plate 6, a secondary pressing plate 9 is fixed to the bottom of the U-shaped frame 8, and a main pressing plate 10 is provided at the bottom of the secondary pressing plate 9. The main pressing plate 10 is used to press the artificial stone slab material in the mold 2. A pressing assembly is provided on the top plate 5. The pressing assembly includes a pressing cylinder 7 fixed to the top of the top plate 5. The output end of the pressing cylinder 7 moves downward through the top plate 5. The lifting plate 6 is fixed to the output end of the pressing cylinder 7 through a connecting flange. When the pressing cylinder 7 works, its output end drives the lifting plate 6 to move up and down on the limit rod 4, which in turn drives the U-shaped frame 8, the secondary pressing plate 9, and the main pressing plate 10 to move up and down, thereby realizing the pressing operation of the artificial stone slab material in the mold 2. To enhance the pressing effect on the artificial stone slab material within mold 2, a set of hammering components is installed within the secondary pressing plate 9. The specific structure of the hammering components is as follows: a first groove 12 is formed within the secondary pressing plate 9, and two air hammers 11 are fixed within the secondary pressing plate 9, both of which are connected to an air compressor. A sliding plate 13 is slidably disposed within the first groove 12, and a rubber pad 14 is fixed to the top of the sliding plate 13. The rubber pad 14 is used to reduce wear on the hammers, anvil, or mold, thereby reducing maintenance costs. Two connecting posts 15 are fixed to the bottom end of the sliding plate 13, and both connecting posts 15 move downwards through the bottom end of the secondary pressing plate 9 and extend downwards. The main pressing plate 10 is fixed to the bottom end of the two connecting posts 15. When the main pressing plate 10 enters the mold 2, it is held in place by the artificial stone slab material. The secondary pressing plate 9 continues to move, causing the slide plate 13 to slide in the first groove 12. A buffer gap is formed between the slide plate 13 and the first groove 12. At this time, the air compressor is started to provide compressed air to drive the two air hammers 11 to hammer downwards. The hammer head of the air hammer 11 hits the rubber pad 14, and through the slide plate 13 and the connecting column 15, it drives the main pressing plate 10 to hammer downwards, thereby effectively compacting the artificial stone slab material. When the air hammer is working, compressed air enters the upper cylinder, pushing the piston rod to extend and the hammer head to the highest position. The control valve switches quickly, the upper cylinder exhausts air, and the lower cylinder is filled with air. The piston rod retracts rapidly under the action of air pressure and gravity, and the hammer head falls at high speed to hit the target. Automatic cycle is achieved through solenoid valves or mechanical cams. The hammering frequency can reach tens to hundreds of times per minute. Adjusting the air pressure and flow rate can change the energy and frequency of a single hammering.

[0016] Simultaneously, the lower cylinder exhausts air to prepare for the hammer's descent. In another embodiment: Refer to Figures 1-3 An improvement upon Example 1: A lifting assembly is provided at the bottom of mold 2 to drive the pressed artificial stone slab material for discharge. The lifting assembly includes a receiving groove 16 within mold 2, and a lifting plate 17 within the receiving groove 16, used to lift the artificial stone slab material. A lifting hydraulic cylinder 3 is fixed to the bottom of mold 2, and the output end of the lifting hydraulic cylinder 3 extends movably into the receiving groove 16 and is fixedly connected to the lifting plate 17. After the artificial stone slab material is pressed and formed, the lifting hydraulic cylinder 3 is activated, and its output end drives the lifting plate 17 to move upward, ejecting the formed artificial stone slab material from mold 2, completing the discharge operation.

[0017] However, as is well known to those skilled in the art, the working principles and wiring methods of the lifting hydraulic cylinder 3, the pressing cylinder 7, and the two air hammers 11 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0018] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
