Description

Technical Field

[0001] This application relates to the technical field of mold polishing, and in particular to a polishing apparatus for glass molds. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface. It involves using polishing tools and abrasive particles or other polishing media to modify the surface of a workpiece.

[0003] Chinese Patent No. CN218341723U discloses a mold polishing device, including a mold placement plate and a mounting block. A support frame is fixedly connected to the upper end of the mold placement plate, a mounting seat is installed on the support frame, a high-frequency telescopic cylinder is installed on the mounting seat, and a mounting block is installed at the output end of the high-frequency telescopic cylinder. The mounting block has a cubic structure and a grinding plate and a polishing plate are fixedly connected to its outer wall. A conversion mechanism is provided between the output end of the high-frequency telescopic cylinder and the mounting block.

[0004] The aforementioned mold polishing device uses a high-frequency telescopic cylinder to move the polishing plate up and down. The polishing plate directly contacts the mold, and the friction from this direct contact generates a lot of heat, which may cause the mold surface temperature to be too high, affecting the performance of the mold material and even causing the mold to deform. Utility Model Content

[0005] To reduce the possibility of deformation of glass molds, this application provides a polishing apparatus for glass molds.

[0006] A polishing device for a glass mold includes a support frame and a high-frequency telescopic cylinder slidably mounted on the support frame. A polishing plate is connected to the piston rod of the high-frequency telescopic cylinder. A liquid storage tank is connected to the support frame. A nozzle is connected to the liquid storage tank via a conveying component. The nozzle is positioned facing the polishing plate.

[0007] By adopting the above technical solution, efficient and stable polishing of glass molds is achieved. Specifically: the combination of the support frame and the high-frequency telescopic cylinder ensures stability and high-frequency vibration during the polishing process, improving polishing efficiency and quality; the connection between the polishing plate and the piston rod of the high-frequency telescopic cylinder enables precise polishing operations; and the liquid storage tank is connected to the nozzle through a conveyor, allowing the polishing liquid to be sprayed evenly and continuously onto the polishing plate, ensuring cooling and lubrication during the polishing process and reducing the possibility of deformation of the glass mold.

[0008] Preferably, the conveying component includes a water pump, a conveying hose, and a positioning ring pipe. The water pump is connected to the liquid storage tank through a first pipe, and the outlet of the water pump is connected to the positioning ring pipe through the conveying hose. A plurality of nozzles are evenly distributed on the positioning ring pipe.

[0009] By adopting the above technical solution, precise control of the polishing slurry flow rate and spray position can be achieved, ensuring a stable and uniform liquid supply during the polishing process, thereby improving polishing quality and efficiency. Specifically:

[0010] The water pump is connected to the liquid storage tank through the first pipe, ensuring a continuous supply of liquid and avoiding flow interruption. The delivery hose connects the water pump and the positioning ring pipe, allowing the liquid to be flexibly transferred to each nozzle, enhancing the system's adaptability and reliability. Multiple nozzles evenly distributed on the positioning ring pipe ensure full coverage of the polishing plate surface, making polishing more uniform and reducing the problem of local over-polishing or under-polishing.

[0011] Preferably, a lifting cylinder is connected to the bracket, a lifting plate is connected to the piston rod of the lifting cylinder, and the lifting plate is connected to the positioning ring tube.

[0012] By adopting the above technical solution, the lifting cylinder allows the positioning ring tube and its nozzle to move up and down, thereby adjusting the nozzle position according to glass molds of different heights. This ensures the nozzle is accurately aligned with the polishing plate, improving the polishing effect. Simultaneously, the lifting plate increases structural stability, guaranteeing smooth operation of the equipment during adjustment.

[0013] Preferably, the top of the liquid storage tank is provided with a recovery port, the recovery port is provided with a filter funnel, the bottom of the filter funnel is closed, the filter funnel is provided with multiple filter holes, the filter funnel blocks the recovery port, and the filter funnel is located directly below the positioning ring tube.

[0014] By adopting the above technical solution, the recovery port at the top of the storage tank can effectively collect the waste liquid generated during the polishing process, preventing waste liquid from splashing out and polluting the environment. The design of the filter funnel allows the waste liquid to be filtered and returned to the storage tank for recycling, improving resource utilization. At the same time, the bottom of the filter funnel is sealed and has multiple filter holes, ensuring that impurities in the waste liquid are effectively intercepted, preventing nozzle clogging, and ensuring the stability and efficiency of the polishing process. The filter funnel is located directly below the positioning ring tube, further optimizing the waste liquid collection path and reducing the risk of waste liquid splashing.

[0015] Preferably, the filter funnel is detachably connected to the liquid storage tank.

[0016] By adopting the above technical solution, a detachable connection between the filter funnel and the storage tank is achieved, which facilitates the cleaning and replacement of the filter funnel, thereby ensuring the cleanliness of the coolant or polishing fluid used in the polishing process, improving the polishing effect and the ease of equipment maintenance.

[0017] Preferably, the bottom of the support frame is provided with a base plate, the base plate has a rotating hole, a load-bearing rod is rotatably arranged in the rotating hole, a locking plate is sleeved on the load-bearing rod, the locking plate is connected to the base plate by bolts, the load-bearing rod is provided with a placement plate for placing the glass mold, and the placement plate is provided with a clamping element for pressing the glass mold.

[0018] By adopting the above technical solution, the load-bearing rod rotatably installed in the rotating hole of the base plate allows the placement plate to rotate with the load-bearing rod and move from above the filter funnel, thus preventing the placement plate from interfering with the upward removal of the filter funnel by the operator. The locking plate is connected to the base plate by bolts to ensure the stability of the load-bearing rod and prevent displacement during polishing. The clamping parts on the placement plate can firmly fix the glass mold and avoid damage or uneven polishing caused by vibration or movement during polishing.

[0019] Preferably, the clamping component includes a plurality of clamping rods, a clamping plate is slidably sleeved on the clamping rods, and a nut is threadedly connected to the top of the clamping rods, the nut pressing the clamping plate against the glass mold.

[0020] By adopting the above technical solution, the clamping component can effectively fix the glass mold, preventing displacement or shaking during polishing and ensuring polishing accuracy and surface quality. Specifically, the design of multiple clamping rods makes the pressure distribution more uniform, avoiding excessive local force that could cause mold deformation. The sliding clamping plate can be adjusted according to different sizes of glass molds, offering strong adaptability. The use of nuts allows for convenient adjustment of the clamping force, ensuring clamping effect while facilitating operation.

[0021] Preferably, a plurality of connecting posts are vertically arranged on the side wall of the filter funnel, and a connecting hole corresponding to each of the plurality of connecting posts is opened on the top surface of the liquid storage tank. The liquid storage tank is made of iron, and a magnet is connected to the bottom end of each connecting post. The connecting post is inserted into the connecting hole, and the magnet attracts the liquid storage tank.

[0022] By adopting the above technical solution, a convenient detachable connection is achieved between the filter funnel and the liquid storage tank, improving the ease of equipment maintenance and cleaning efficiency. The design of the connecting column and magnetic column ensures a stable installation of the filter funnel, preventing loosening or detachment due to vibration during polishing, thus ensuring the stability and safety of the polishing process. At the same time, the magnetic connection simplifies the assembly and disassembly steps of the filter funnel, reduces operational difficulty, and improves work efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a liquid storage tank on the support frame and connecting the nozzle to the conveyor, with the nozzle facing the polishing plate, the automatic supply of polishing liquid is realized, so that the polishing liquid can be sprayed evenly and continuously onto the polishing plate, ensuring the cooling and lubrication effect during the polishing process and reducing the possibility of deformation of the glass mold;

[0025] 2. The delivery components include a water pump, a delivery hose, and a positioning ring tube. Multiple nozzles are evenly distributed on the positioning ring tube to ensure the uniform distribution of polishing fluid and avoid poor polishing effect caused by uneven polishing fluid.

[0026] 3. A lifting cylinder is connected to the support frame, and a lifting plate is connected to the piston rod of the lifting cylinder. The lifting plate is connected to the positioning ring tube, so that the height of the nozzle can be adjusted to adapt to glass molds of different sizes and shapes, thereby improving the applicability and flexibility of the equipment.
