A low-thermal-stress glass mold and its preparation method are disclosed, belonging to the field of glass mold technology. The mold includes a bottle half-mold used in pairs, facing each other towards one side of a pair of mold-fitting surfaces. The bottle half-mold has a cavity, characterized by: within the wall thickness of the bottle half-mold, axially arranged, independent yet spaced apart, each penetrating from one side of the pair of mold-fitting surfaces to the other, comprising a lower built-in annular cavity, a middle built-in annular cavity, and a neck / shoulder built-in annular cavity. The openings of the lower, middle, and neck / shoulder built-in annular cavities are closed at the points where they meet the mold-fitting surfaces. Advantages: Without changing the inner wall dimensions and cooling boundary conditions, it solves the problem of high thermal stress caused by large radial temperature gradients in solid glass molds, extending service life; the method has controllable manufacturing costs, feasible processes, and ensures a significant reduction in thermal stress in the prepared glass mold.

The application provides a special-shaped bottle production process and belongs to the technical field of glass bottle production, and solves the problem that the prior art is concentrated on adjusting blowing parameters or single mold material, and the yield of special-shaped bottle production is long-term hovering at a low level due to the existence of scissor scars and demolding damage. The special-shaped bottle production process comprises the following steps: S1, raw material preparation, S2, high-temperature solution preparation, S3, forming, S4, annealing, S5, post-treatment, S6, detection and packaging, and the high-heat-conducting wear-resistant synthetic resin forming die in the forming step S3 is made of a special synthetic resin composite material, which comprises, by weight, 45-60 parts of high-temperature-resistant epoxy resin, 30-40 parts of high-heat-conducting modified filler, 10-15 parts of wear-resistant reinforcing filler and 2-5 parts of internal demolding agent. The application has the advantages of solving the problem that the yield of special-shaped bottle production is long-term hovering at a low level due to the existence of scissor scars and demolding damage.

This disclosure describes substrate(s) (10) formed with a three-dimensional (3D) feature (12) thereon, and method(s) of printing the same. One method includes identifying a plurality of locations (32) on a substrate surface (18) where the three-dimensional feature will be formed, determining a height value of the three-dimensional feature at each location, assigning a grayscale value to each location based on the height value, and applying ink to the substrate surface at each location according to the assigned grayscale value.

To provide a blow-and-blow molding device that can arrange a baffle mark radially inside a bottle.SOLUTION: A blow-and-blow molding device 1 has a rough mold 4, a funnel 5 and a baffle 6. A lower part of the baffle has a baffle-side mold surface 41, a first outer peripheral surface 42, a first figure top surface 43, and a second outer peripheral surface 44 which are arranged in order from below. The second outer peripheral surface is formed into a conical surface which becomes narrower in width downward, and can come into surface contact with an inner peripheral surface upper part 29 of the funnel. The first figure top surface is formed into an annular plane and connected to a lower end of the second outer peripheral surface at its outer peripheral edge, and can come into surface contact with a second wall surface 24. The first outer peripheral surface is formed into a conical surface which extends downward from an inner peripheral edge of the first figure top surface and becomes narrower in width downward, and can come into surface contact with a third wall surface 25. The baffle-side mold surface is connected to a lower end edge of the first outer peripheral surface. The baffle has a compressed air path 51 which is open on the first figure top surface.SELECTED DRAWING: Figure 2

This invention discloses a blowing device and method for insulated double-layered glassware, belonging to the technical field of glassware manufacturing equipment. It includes a blowing device, a preliminary shaping device, a pre-forming device, and a rotating mechanism. The pre-forming device is installed on the side of the preliminary shaping device, and the rotating mechanism is assembled at the rear end of the blowing device. The blowing device is mounted on the preliminary shaping device and the pre-forming device. The blowing device and method of this invention use a micro-motor for power, significantly reducing labor intensity and improving shaping efficiency compared to manual rotation. Drilling a hole in the molten glass provides a breakthrough point for blowing the glass. The use of a power device for rotation and blowing replaces manual operation, allowing the operator to focus on observing the forming state of the molten glass and adjusting the blowing volume, rotation speed, and angle based on the real-time forming status, thus improving the quality of the blown glass.
