Description

Technical Field

[0001] This utility model relates to the technical field of gating and riser cutting equipment, and in particular to a glass mold gating and riser cutting and feeding fixture. Background Technology

[0002] Glass molds are crucial tools in the glass manufacturing process, and the cutting quality of their risers and gating systems directly affects the final product's molding precision. Currently, the riser and gating cutting process still faces numerous technical challenges in the glass mold manufacturing industry. Traditional feeding fixtures often employ simple planar load-bearing structures combined with general-purpose jigs, which have revealed significant technical deficiencies in practical applications.

[0003] First, the positioning accuracy of existing tooling is insufficient. Due to the lack of an effective contour-following positioning structure, the mold is prone to displacement during the cutting process, especially during continuous feeding operations. Accumulated errors can lead to deviations in the cutting position, severely affecting the quality of the gating and riser removal. Second, traditional clamping mechanisms suffer from insufficient stability. Most clamps use a unidirectional clamping method, which cannot evenly distribute the clamping force and is difficult to adapt to the fixing requirements of molds with different diameters. Replacement and adjustment are time-consuming and labor-intensive. More seriously, rigid clamping can easily cause damage to the mold surface, affecting subsequent use.

[0004] Furthermore, low production efficiency is also a pressing issue. The single-station design necessitates frequent machine stops for loading and unloading during production, resulting in numerous manual operations and low automation levels, severely hindering the efficiency of mass production. Poor equipment adaptability is equally prominent; existing tooling struggles to accommodate molds of different specifications, with particularly unsatisfactory fixation for molds of special shapes. These technical deficiencies collectively contribute to the current problems of unstable quality, low efficiency, and high costs in the glass mold gating and riser cutting process. Utility Model Content

[0005] The purpose of this invention is to provide a glass mold gating and riser cutting and feeding fixture that can achieve precise positioning and stable clamping of the glass mold, as well as efficient cutting of the gating and riser, and has good adaptability and reliability to meet the strict requirements of modern production.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a glass mold gating and riser cutting and feeding fixture, including:

[0008] The feeding plate has one end fixedly connected to the drive end of the feeding robot. The feeding plate has several loading stations spaced apart along its length. Each loading station is recessed to form a trough for accommodating the riser and gating gate. The trough has a cutting clearance opening on its side to provide cutting space for the cutting assembly.

[0009] The first conforming pressure plate is disposed on one side of the feeding plate and is used to limit and fix one side of the glass mold.

[0010] The second contouring press is movably disposed on the other side of the feeding sheet and connected to the feeding robot, and is used to cooperate with the first contouring press to clamp the glass mold;

[0011] An upper pressure plate is disposed above and connected to the feeding plate, and is used to press against the upper end of the glass mold during the cutting operation.

[0012] Furthermore, the ratio of the width W of the feed piece to the diameter D of the glass mold satisfies 0.8 ≤ W / D ≤ 1.5.

[0013] Furthermore, the first contouring plate is fixed to the side of the feeding plate by bolts, and the inner side of the first contouring plate is provided with a first contouring surface that matches the outer contour of the glass mold.

[0014] Furthermore, the inner side of the second contouring press is provided with a second contouring surface that matches the outer contour of the glass mold.

[0015] Furthermore, the opening direction of the cutting clearance is perpendicular to the feeding direction of the feeding sheet.

[0016] Furthermore, a positioning hole is provided at one end of the feeding plate, and the feeding plate is bolted to the drive end of the feeding robot through the positioning hole.

[0017] Furthermore, the upper pressure plate is connected to the feeding plate by bolts, and a return spring is sleeved on the bolts to push the upper pressure plate upward when the bolts are loosened.

[0018] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0019] This utility model discloses a glass mold gating and riser cutting and feeding fixture, which adopts a design of contour pressing plate combined with a sunken loading station to achieve three-dimensional precise positioning of the mold; the double-sided contour pressing plate covering clamping structure ensures a stable fixing effect; and the design of the cutting clearance port avoids interference between the cutting components.

[0020] Furthermore, the pressure adjustment mechanism of the upper pressure plate bolts in conjunction with the reset spring achieves adaptive clamping.

[0029] 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.

[0030] See Figures 1 to 3 This utility model discloses a glass mold gating and riser cutting and feeding fixture, which includes a feeding plate 1, a first contouring pressure plate 2, a second contouring pressure plate 3, and an upper pressure plate 4. The components work together to ensure the stability and accuracy of the gating and riser cutting process.

[0031] Specifically, one end of the feeding plate 1 is fixedly connected to the drive end of the feeding robot. The feeding plate 1 has several positioning holes 103. Bolts are installed at the positioning holes 103 to connect the feeding plate 1 and the drive end of the feeding robot. The feeding robot can drive the feeding plate 1 to move smoothly and accurately on a preset trajectory, thereby moving the cutting station.

[0032] On the feeding plate 1, several loading stations 10 are spaced apart along its length. The number of loading stations 10 can be flexibly adjusted according to actual production needs. Each loading station 10 is recessed to form a trough 101 for accommodating the gating gate 6 of the glass mold 5. The main body of the glass mold 5 is correspondingly positioned on the plane of the feeding plate 1 on both sides of the trough 101. A cutting clearance opening 102 is provided on the side of the trough 101. The opening direction of the cutting clearance opening 102 is perpendicular to the feeding direction of the feeding plate 1, which is used to provide corresponding cutting space for the cutting component and ensure that there is no interference during the cutting process.

[0033] In this example, the ratio of the width W of the feed piece 1 to the diameter D of the glass mold satisfies 0.8 ≤ W / D ≤ 1.5. When W / D < 0.8, the feed piece 1 is too narrow, resulting in insufficient mold support area and affecting clamping stability. When W / D > 1.5, the feed piece 1 is too wide, increasing material consumption and affecting the working space of the cutting assembly. The ratio range of 0.8 to 1.5 selected in this example ensures sufficient support strength while maintaining structural compactness. Furthermore, within this ratio range, the deformation of the feed piece 1 is minimal when subjected to cutting loads.

[0034] The first contouring pressure plate 2 is disposed on one side of the feeding plate 1 and is used to limit and fix one side of the glass mold 5. The first contouring pressure plate 2 is fixed to the feeding plate 1 by bolts to ensure that no displacement occurs during the cutting process. The inner side of the first contouring pressure plate 2 is machined with a first contouring curved surface that matches the outer contour of the glass mold 5, which not only improves the positioning accuracy, but also effectively disperses the clamping pressure and avoids damage to the mold surface.

[0035] The second contouring pressing plate 3 is movably positioned on the other side of the feeding plate 1 and is linked to the feeding robot. The inner side of the second contouring pressing plate 3 also has a second contouring surface that matches the outer contour of the glass mold 5. After completing a cutting operation at a loading station 10, the second contouring pressing plate 3, driven by the feeding robot, performs an avoidance action and moves away from the mold. Simultaneously, driven by the feeding robot, the feeding plate 1 accurately moves the next loading station 10 to the cutting area. At this time, the second contouring pressing plate 3 moves closer to the mold, achieving progressive contact clamping through the contouring surface.

[0036] The second contouring clamping plate 3 works in conjunction with the first contouring clamping plate 2 to form a wrapping clamping grip on the glass mold 5. This not only ensures the stability of the clamping but also adapts to the processing requirements of molds of different sizes.

[0037] The upper pressure plate 4, connected to the feeding plate 1 by bolts and located above the feeding plate 1, is used to press against the upper surface of the glass mold 5 during the cutting operation. The clamping force on the upper surface of the glass mold 5 is adjusted by tightening the bolts. A return spring (not shown in the figure) is fitted on the bolts, which pushes the upper pressure plate 4 upwards when the bolts are loosened. The upper pressure plate 4 can adjust the clamping force according to the mold height, ensuring reliable fixation during the cutting process and effectively preventing mold deformation due to excessive pressure. The preload of the return spring can be precisely adjusted according to the characteristics of different molds, further improving the adaptability and reliability of the tooling.

[0038] In summary, the glass mold gating and riser cutting and feeding fixture disclosed in this utility model includes a feeding plate 1, a contouring pressing plate assembly, and an upper pressure plate 4. The feeding plate 1 adopts a multi-station design and features a precise countersunk groove 101 structure, coupled with a specially proportioned width (W / D=0.8~1.5), ensuring both support strength and structural compactness. The double-sided contouring pressing plates achieve mold-wrapping clamping through precise contoured curved surfaces, while the upper pressure plate 4 achieves adaptive pressure adjustment through a bolt connection mechanism with a return spring. The entire fixture boasts outstanding advantages such as precise positioning, stable clamping, and controllable pressure, adapting to the processing needs of molds of different specifications. It significantly improves the quality stability and production efficiency of gating and riser cutting, and has significant application value in the glass mold processing field.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model.
