Description

Technical Field

[0001] This utility model relates to the field of glass mold processing technology, and in particular to a back milling processing device for glass molds. Background Technology

[0002] In the manufacturing process of glass molds, precision milling of the back spray welding area and the hanging pin groove area (usually a protruding outer circle structure) is a crucial step. Currently, the traditional machining method commonly used in the industry is horizontal clamping and single-piece machining. Specifically, the operator needs to place the single mold horizontally (i.e., horizontally) on a vise, manually align and clamp it, and then use a ball end mill for cutting.

[0003] This traditional process has the following significant drawbacks: Low clamping efficiency: Each mold piece needs to be clamped and aligned individually, and the clamping time with flat-nose pliers alone is about 5 minutes per piece. A mold set usually consists of multiple pieces, which leads to a corresponding increase in clamping time.

[0004] The machining cycle is lengthy: limited by the stability of horizontal clamping and the single-point cutting machining method, the pure milling time for a single mold is about 30 minutes. The total machining time for a mold is as long as about 70 minutes, making production efficiency a bottleneck in manufacturing.

[0005] Machining accuracy and consistency are difficult to guarantee: Repeated clamping inevitably introduces cumulative errors, resulting in poor dimensional consistency between different mold pieces and affecting the quality of the finished product. At the same time, when clamped horizontally, the workpiece has poor overhang stability and is prone to vibration under cutting forces, affecting the quality of the machined surface. Utility Model Content

[0006] The purpose of this invention is to provide a back milling processing device for glass molds, which solves the problems of low processing efficiency, long clamping auxiliary time, and difficulty in ensuring processing accuracy and consistency in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a back milling processing device for glass molds, including: Booth seating; A chuck, which is detachably mounted on the chuck base, has several sliding grooves on its upper surface; A fixing block, which is embedded in the sliding groove. A clamping block, which is movably mounted on the fixed block, is used to radially clamp the glass mold; The fixing block has a through groove in the middle, and a limit block is provided in the through groove. The clamping block and the limit block have positioning holes through them. Fasteners are provided at the positioning holes to fix the clamping block and the limit block to the fixing block, so as to realize the adjustment and locking of the clamping position of the clamping block. The milling cutter body is vertically disposed on the side of the glass mold and is used to cut the protruding edges on the side surface of the glass mold.

[0008] Furthermore, the card holder is provided with several parallel fixing grooves spaced apart, and the cross-sectional shape of the fixing grooves is inverted T-shaped.

[0009] Furthermore, the grooves are distributed at equal angles on the chuck.

[0010] Furthermore, the clamping block includes a clamping portion and a flat portion. The flat portion is used to support the glass mold, and the clamping portion is used to radially clamp the glass mold. The end face contour of the clamping portion facing the glass mold is adapted to the outer contour of the clamping part of the glass mold.

[0011] Furthermore, the outer contour of the limiting block is adapted to the inner contour of the through groove.

[0012] Furthermore, the top of the fixing block is provided with a protruding rib, and the bottom of the clamping block is provided with a protruding rib groove that matches the protruding rib.

[0013] Furthermore, the chuck has a shaft hole in the middle, and the sliding grooves are connected to the shaft hole and arranged radially relative to the shaft hole.

[0014] Furthermore, it also includes an annular constraint band, which is fitted around the entire glass mold after it is radially clamped by the clamping block, and works in conjunction with the clamping block to prevent the glass mold from shifting during the cutting operation.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The glass mold back milling processing device of this utility model integrates a chuck, a fixing block, a limiting block and a clamping block, to realize the one-time clamping and positioning of the entire mold, eliminating the accumulated auxiliary time caused by repeated clamping in traditional single-piece processing, and significantly improving clamping efficiency.

[0016] Furthermore, the use of radially distributed sliding grooves and clamping mechanisms centered on the shaft hole ensures automatic centering and consistent datum for the entire mold, effectively avoiding cumulative errors caused by multiple clamping operations. The adaptability design of the clamping block end face to the outer contour of the mold further improves clamping stability and positioning accuracy, ensuring product dimensional consistency.

[0017] Furthermore, the vertical clamping method lowers the center of gravity of the mold. Combined with the stable connection of the inverted T-shaped fixing groove on the chuck and the auxiliary binding of the annular constraint belt, it can effectively suppress cutting vibration, which not only improves the quality of the machined surface, but also extends the service life of the milling cutter body.

[0018] Furthermore, the clamping block achieves flexible movement and precise locking on the fixed block through the cooperation of the limiting block, the rib and the rib groove, which enables the device to quickly adapt to glass molds of different sizes and specifications, making it highly versatile and flexibly adjustable.

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] See Figures 1 to 3This example provides a back-end milling device for glass molds. By improving the clamping method of the glass mold, it achieves vertical, centering, rapid clamping and efficient precision milling of the entire glass mold, effectively solving the problems of low efficiency, poor accuracy and insufficient consistency in traditional horizontal single-piece processing.

[0022] Specifically, the core components of the device include a chuck 1, a chuck 2, a fixing block 3, a clamping block 4, a limiting block 5, a milling cutter body 6, and an annular constraint band. Each component has a clearly defined function and works together to form a complete back milling system.

[0023] The chuck 1 serves as the mounting base for the entire device. Its upper surface is provided with several parallel fixing grooves 10. The cross-sectional shape of the fixing grooves 10 is inverted T-shaped, which is used to realize the quick positioning and rigid connection between the chuck 2 and the chuck 1.

[0024] The chuck 2 is detachably mounted on the chuck base 1 by bolts, forming a clamping module. A shaft hole 21 is opened in the middle of the chuck 2, which serves as the centering reference for the entire clamping system. Around the shaft hole 21, several sliding grooves 20 are radially and equally angled on the upper surface of the chuck 2. The sliding grooves 20 pass through the shaft hole 21 and are used for precise installation and positioning of the fixing block 3.

[0025] The number of fixing blocks 3 corresponds to the number of slide grooves 20, and each block is embedded in one of the slide grooves 20 and fixed to the chuck 2 by threads. The top of each fixing block 3 is provided with a raised rib 31, and a T-shaped through groove 30 is formed along its length in the middle. The clamping block 4 rests on the fixing block 3 through a raised rib groove 42 at its bottom that matches the raised rib 31. This raised rib-groove structure ensures that the clamping block 4 can move precisely along the direction of the raised rib 31, while effectively preventing lateral displacement, thereby achieving fine adjustment of the clamping position.

[0026] The clamping block 4 consists of a clamping part 40 and a flat part 41. The flat part 41 is used to support the bottom surface of the glass mold, while the clamping part 40 is used to clamp the outer periphery of the glass mold. The contour of the end face of the clamping part 40 facing the mold is conformally matched with the outer contour of the clamping part of the glass mold, achieving large-area surface contact clamping. This improves clamping stability and effectively avoids damage to the mold surface caused by point-line contact.

[0027] To achieve precise adjustment and reliable locking of the clamping block 4, a limiting block 5 is provided in the through groove 30 of the fixing block 3. The outer contour of the limiting block 5 matches the inner contour of the through groove 30, ensuring that it will not wobble within the through groove 30. Positioning holes are correspondingly provided on the clamping block 4 and the limiting block 5. During assembly, fasteners (such as bolts) are inserted into the positioning holes and tightened. The tension effect of the threaded connection between the bolt and the limiting block 5 presses the clamping block 4 firmly onto the fixing block 3. This structure achieves stepless adjustment and rigid locking of the clamping position of the clamping block 4.

[0028] To further enhance the overall rigidity of the entire mold under cutting forces and prevent fretting or displacement during processing, in this example, an annular constraint band (not shown in the figure) is fitted around the entire glass mold after it is radially clamped by clamping block 4. This constraint band works in conjunction with the radially clamping clamping block 4 to form a composite constraint system, effectively suppressing vibration and displacement during processing.

[0029] The milling cutter body 6 (preferably a T-type milling cutter) is vertically mounted on the side of the glass mold. Once the mold is reliably fixed, the milling cutter body 6 can perform efficient and precise cutting of the protruding edges (i.e., the back spray welding area / hanging nail groove area) on the side surface of the glass mold in a vertically clamped state.

[0030] This utility model, through the aforementioned modular and adjustable clamping system, realizes the process adjustment of glass mold back processing from "horizontal single piece" to "vertical whole set", achieving significant progress in efficiency, precision and consistency.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly.
