Description

Technical Field

[0001] This utility model relates to the field of artificial quartz stone production technology, and in particular to a vacuum vibration pressing device for artificial quartz stone. Background Technology

[0002] Artificial quartz stone is a new type of green and environmentally friendly decorative material made primarily from quartz sand, supplemented with resin and other additives, through processes such as pressing and curing. Currently, the pressing and molding process for artificial quartz stone commonly employs atmospheric pressure vibration or simple mold pressing methods, but these methods have the following problems: Ordinary pressing equipment often relies solely on vibration or mechanical pressure during the pressing process, resulting in residual gas in the material, low product density, and insufficient strength. Furthermore, when the vibration motor acts directly on the mold, it often causes equipment resonance or transmits the vibration to the equipment base, causing the entire equipment to shake and affecting the pressing stability.

[0003] Therefore, we propose a vacuum vibration pressing device for artificial quartz stone to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a vacuum vibration pressing device for artificial quartz stone.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum vibration pressing device for artificial quartz stone, comprising a base plate, a mold chamber, and a support plate. Columns are symmetrically fixedly arranged on the base plate, and a beam plate is fixedly arranged at the top of each column. A hydraulic cylinder is fixedly arranged on the beam plate. A mold cover is movably sleeved on the output arm of the hydraulic cylinder. A pressure plate is fixedly arranged at the bottom end of the output arm of the hydraulic cylinder. An upper spring is sleeved on the output arm of the hydraulic cylinder. The upper spring applies an elastic thrust to the mold cover to press the pressure plate. Air nozzles are symmetrically opened on the mold cover. The mold chamber is mounted on the base plate via various sets of vibration damping mechanisms. A vibration motor is fixedly mounted on the lower surface of the mold chamber. The vibration damping mechanism includes a damping rod and a lower spring. The two ends of the damping rod are respectively mounted on the outer wall of the mold chamber and the upper surface of the base plate. The lower spring is sleeved on the damping rod. The support plate is raised and lowered directly below the mold chamber.

[0006] Preferably, guide blocks are fixedly provided at equal intervals on the lower surface of the mold cover. The guide blocks are designed in the shape of right-angled trapezoids, and the mold cover can be quickly spliced ​​and fitted with the mold chamber through the guide blocks.

[0007] Preferably, the upper opening of the mold chamber is in the shape of an open cone, the inner diameter of the cone is larger than the diameter of the pressure plate, and the diameter of the pressure plate is adapted to the lower inner diameter of the mold chamber.

[0008] Preferably, bushings are symmetrically fixed at both ends of the damping rod, and mounting heads are rotatably mounted on the bushings. The mounting heads are respectively fixed on the mold chamber and the base plate.

[0009] Preferably, a second hydraulic cylinder is symmetrically fixedly disposed on the lower surface of the mold chamber, and an ejector block is fixedly disposed at the output end of the second hydraulic cylinder, the ejector block being slidably inserted into the bottom end of the inner wall of the mold chamber.

[0010] Preferably, guide rods are symmetrically fixed on the mold cover, and the guide rods are slidably inserted into the beam plate.

[0011] Preferably, the base plate has a built-in hydraulic cylinder three, and the output end of the hydraulic cylinder three is fixedly disposed on the lower surface of the support plate.

[0012] Preferably, a rubber sealing ring is fixedly provided at the contact surface between the upper surface of the mold chamber and the top of the inner wall of the mold cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the artificial quartz vacuum vibration pressing equipment of this utility model is connected to an external power source. Personnel introduce a specified amount of artificial quartz material into the mold chamber. A cone-shaped opening is set at the upper end of the mold chamber and is connected to an external air extraction device through an air nozzle on the mold cover. Before pressing, the internal space of the mold chamber can be vacuumed, which significantly reduces residual gas and air bubbles inside the material. With the work of the vibration motor, the material particles are fully compacted in the vacuum environment, and the density of the quartz product after pressing is significantly improved. A right-angled trapezoidal guide block is provided on the lower surface of the mold cover. During the process of the mold cover descending and closing the mold, the guide block can form a limiting and guiding effect with the edge of the mold chamber, thereby avoiding misalignment or displacement between the mold cover and the mold chamber, improving the accuracy and stability of mold closing, and ensuring that the pressure plate always acts on the center of the material during pressing. The mold chamber is mounted on the base plate through a vibration damping mechanism consisting of a damping rod and a lower spring. The damping rod can effectively dissipate the impact energy brought by the vibration motor, and the lower spring can disperse and alleviate the impact load, thereby preventing the vibration of the mold chamber from being directly transmitted to the base plate and the overall frame of the equipment. This structure not only ensures the full vibration effect of the mold chamber, but also improves the stability of the whole machine operation and reduces the noise and mechanical wear of the equipment. The base plate has a built-in hydraulic cylinder three, the output end of which is connected to the support plate. During the pressing process, the hydraulic cylinder three drives the support plate to move upward and abut against the lower surface of the mold chamber, providing a stable and reliable support force to the mold chamber. This prevents the mold chamber from sinking or shifting when it is subjected to the pressure of the pressure plate, thereby ensuring that the material is pressed evenly and improving the homogeneity of the molded product. A second hydraulic cylinder is installed at the bottom of the mold chamber. The output end of the second hydraulic cylinder is connected to the ejector block. After pressing, the ejector block can move upward along the bottom of the inner wall of the mold chamber to smoothly eject the molded workpiece. Compared with the traditional demolding method that relies on manual knocking or prying, this structure makes the demolding process more efficient and safe, and greatly reduces workpiece damage and manual labor intensity.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 like Figures 1-5 As shown, the present invention proposes a vacuum vibration pressing device for artificial quartz stone, including a base plate 1, a mold chamber 4 and a support plate 8. The base plate 1 serves as the load-bearing foundation of the device, and two columns 2 are symmetrically fixed on its upper surface. The two columns 2 are arranged vertically to support the upper beam plate 3. The beam plate 3 is horizontally fixed to the top of the columns 2 to form the upper frame of the device, which is used to install the hydraulic cylinder 6.

[0018] Hydraulic cylinder 6 is fixed to the lower surface of beam plate 3. Its output arm extends vertically downward. Mold cover 5 is movably sleeved on the outside of the output arm. Pressure plate 15 is fixed at the bottom end of the output arm. Upper spring 14 is sleeved in the middle of the output arm. Upper spring 14 applies elastic thrust to the mold cover 5 to press the mold chamber 4. Right-angled trapezoidal guide blocks 11 are fixed at equal intervals along the ring edge of the lower surface of mold cover 5. When mold cover 5 moves downward, guide blocks 11 and the outer edge of mold chamber 4 engage with each other to avoid misalignment between mold cover 5 and mold chamber 4, thus achieving fast and accurate mold closing. Air nozzles 12 are symmetrically arranged on the upper surface of mold cover 5. Air nozzles 12 are connected to the external vacuum pump pipeline to create a vacuum environment in mold chamber 4 after mold closing. Guide rods 13 are fixed on both sides of mold cover 5. Guide rods 13 penetrate beam plate 3 and are installed in a sliding fit to keep mold cover 5 parallel and stable during up and down movement, avoiding shaking.

[0019] Example 2 like Figures 1-5 As shown, the present invention proposes a vacuum vibration pressing device for artificial quartz stone. Compared with Embodiment 1, this embodiment further includes: a mold chamber 4 installed in the center of the base plate 1, supported below by multiple sets of vibration damping mechanisms 7. The vibration damping mechanism 7 is composed of a damping rod 703 and a lower spring 704. Bushings 702 are fixed at both ends of the damping rod 703, and mounting heads 701 are rotatably connected to the bushings 702. The mounting heads 701 are respectively fixed to the outer wall of the mold chamber 4 and the upper surface of the base plate 1. The lower spring 704 is sleeved on the outside of the damping rod 703, capable of... The vibration motor 10 absorbs and disperses the impact load brought by the vibration motor 10, achieving a good vibration reduction and buffering effect. The vibration motor 10 is installed on the lower surface of the mold chamber 4. When the vibration motor 10 is working, it causes the mold chamber 4 to vibrate, so that the introduced quartz material is fully compacted in the mold cavity. The upper opening of the mold chamber 4 is processed into a cone-shaped structure. The inner diameter of the cone is larger than the diameter of the pressure plate 15, ensuring that the air below the pressure plate 15 can be smoothly extracted. The lower inner diameter of the mold chamber 4 matches the diameter of the pressure plate 15, thereby ensuring that the pressure plate 15 can fit tightly with the mold cavity when it is pressed down.

[0020] The support plate 8 is raised and lowered directly below the mold chamber 4. A hydraulic cylinder 3 is installed inside the base plate 1. The output end of the hydraulic cylinder 3 is fixedly connected to the lower surface of the support plate 8. During the pressing process, the hydraulic cylinder 3 drives the support plate 8 to move upward and press against the bottom of the mold chamber 4, forming a stable support force to prevent the mold chamber 4 from sinking or shifting when subjected to the downward pressure of the upper pressure plate 15. A second hydraulic cylinder 9 is symmetrically installed at the bottom of the mold chamber 4. The output end of the second hydraulic cylinder 9 is connected to the ejector block 16. The ejector block 16 is slidably inserted into the bottom groove of the inner wall of the mold chamber 4. After pressing is completed, the second hydraulic cylinder 9 moves upward to push the ejector block 16 and smoothly ejects the molded workpiece from the mold cavity.

[0021] A rubber sealing ring is installed between the upper surface of the mold chamber 4 and the contact area between the top of the inner wall of the mold cover 5. When the mold cover 5 moves down and fits against the mold chamber 4, the rubber sealing ring achieves the sealing effect of the vacuum cavity, ensuring that no air leakage occurs during the vacuuming process.

[0022] When in use, connect to an external power source. First, pour the proportioned artificial quartz material into the mold cavity through the cone-shaped opening of the mold chamber 4. Start the vibration motor 10, and the mold chamber 4 will vibrate to make the material evenly distributed and gradually piled up in the mold cavity. Then stop the vibration. Next, the hydraulic cylinder 6 is started to drive the mold cover 5 downward. The guide block 11 and the mold chamber 4 are matched to achieve precise mold closing. At this time, the air nozzle 12 is connected to the external vacuum pump to perform vacuum treatment in the mold chamber 4 to reduce residual gas in the material. Hydraulic cylinder three drives the support plate 8 to move upward, firmly supporting the bottom of the mold chamber 4 to prevent the mold chamber 4 from shifting during the pressing process. Hydraulic cylinder one 6 continues to move downward to push the pressure plate 15, pressing the material under vacuum and vibration conditions. After the molding is completed, hydraulic cylinder one 6 drives the pressure plate 15 to move upward and reset. Hydraulic cylinder two 9 works to drive the ejector block 16 to move upward, ejecting the pressed quartz stone product out of the mold cavity, achieving rapid demolding.

[0023] It should be noted that the hydraulic cylinder structure is a mature existing technology, and its working principle and internal structure are known to those skilled in the art. This utility model only utilizes its function and does not improve its internal structure. Therefore, it will not be described in detail here.
