Problems solved by technology

[0002] At present, most of the hollow containers sold on the market are cylindrical and conical. The production of traditional cylindrical and conical plastic objects, such as water cups and cylindrical plastic utensils, are all injection molded first and then printed on the outside. The surface has a certain curvature, and now generally only pad printing technology or screen printing technology can be used, and the above two forms of printing can only be printed with ordinary color blocks, line plates or coarse dots (50-150 screen lines). It is impossible to achieve exquisite printing on the above-mentioned objects (products), let alone some technological high-end printing, such as three-dimensional effects, animation effects, etc.

Embodiment 1

[0022] Use a four-color Japanese Komori Reiseron offset printing machine to print color images on the lenticular film made of polypropylene (PP) resin, and the image can be selected according to needs; then die-cut the lenticular film with the printed color image with a die-cutting machine Form into a fan shape, and then put the fan-shaped grating film into a mold with an inner core A3 and an outer core A4 that cooperate with each other. The surface of the mold core body is an annular cone surface and the height of the outer core A4 is slightly higher than the inner core A3. In the mold, the fan-shaped grating film is surrounded by a ring-shaped cone surface to match the shape of the mold. The injection molding machine adopts ZY-180 hydraulic plastic injection molding machine, and the temperature of the nozzle of the injection molding machine is kept at 200°C. Polypropylene (PP) resin is injected into the mold from the top of the mold, that is, the smallest end of the mold cor...

Embodiment 2

[0025] The nozzle temperature of the injection molding machine was kept at 220° C., and the production process was the same as in Example 1.

Embodiment 3

[0027] Use a four-color Japanese Komori Reiseron offset printing machine to print color images on a lenticular film made of polyethylene terephthalate (PET) resin, and the image can be selected according to needs; The cutting machine die-cuts the rectangle, and then puts the rectangular grating film into a mold with an inner core B3 and an outer core B4 that cooperate with each other. The inner core B3 of the mold is a cylinder, and the inner surface of the outer core B4 is a cylindrical surface, and the outer core B4 There is a certain gap between the core B4 and the inner core B3, and its thickness is the thickness of the container wall after molding. In the mold, the rectangular grating film is surrounded by a cylindrical surface and is close to the inner wall of the outer core B4 of the mold. The injection molding machine adopts ZY-500 hydraulic plastic injection molding machine. The nozzle temperature of the injection molding machine is kept at 260 ° C. Polyethylene terep...

Abstract

The invention discloses a preparing method and mould of hollow container with print material, which comprises the following steps: (1) printing image on the film material, (2) cutting the printed film material mould into the needed shape and size, (3) starting mould, placing the cut film material in the mould cavity, locking the mould, (4) heating the plastic, spraying the plastic in the mould through the sprayer of injection machine, (5) cooling, starting the mould, stripping. The mould possesses inner core and outer core with the height of external core higher than inner core with inner core connecting extending device or inner core possessing gap with external core.

Description

technical field [0001] The invention relates to the field of plastic products, in particular to a method for manufacturing a hollow container with printed matter and a mold used therefor. Background technique [0002] At present, most of the hollow containers sold on the market are cylindrical and conical. The production of traditional cylindrical and conical plastic objects, such as water cups and cylindrical plastic utensils, are all injection molded first and then printed on the outside. The surface has a certain curvature, and now generally only pad printing technology or screen printing technology can be used, and the above two forms of printing can only be printed with ordinary color blocks, line plates or coarse dots (50-150 screen lines). It is impossible to realize exquisite printing on the above-mentioned objects (products), and it is even more impossible to realize some technological high-grade printing, such as three-dimensional effects, animation effects, etc. ...
