Embodiment Construction

[0055] Please refer to Figure 1 to Figure 9 Shown, it has shown a kind of compression molding bottle cap forming method of the present invention, comprises the following steps:

[0056] First, feeding: see figure 2 , the suction machine sucks the mixed material into the bubble barrel 10 of the compression molding machine, and heats it to 160-180°C in the barrel, so that the plastic material becomes semi-melted and plasticized and extruded quantitatively. The billet is cut and placed on the distribution tray 11, and the distribution tray 11 rotates rapidly;

[0057] Second, compression molding: combining figure 2 with image 3 As shown, the upper mold 21 and the lower mold 22 of the thermal molding machine are installed in the forming conveying turntable 20, driven by the forming conveying turntable 20 to rotate counterclockwise, and 6 processes are completed during one rotation.

[0058] (1) Unloading: The upper mold 21 and the lower mold 22 are separated at the unloadi...

Abstract

The invention discloses a forming method of compression molding bottle caps. The forming method comprises the five procedures of feeding, compression molding forming, bottle cap flanging and shaping, ring cutting and cushioning. The bottle caps are manufactured in a compression molding forming manner, the forming period of the bottle caps can be shortened as far as possible by means of a cap pressing machine, and the bottle caps can be produced as many as possible within the same time with the same number of cavities, so that energy consumption of the single bottle caps is reduced. Due to the fact that the finished plastic bottle caps cannot be produced at a time by means of cap pressing equipment, the procedures of cap turnover and ring cutting are added, and the bottle caps have the antitheft function. A procedure of inner cushion forming or outer cushion forming needs to be added for dual-sheet caps, the sealing performance of the bottle caps is enhanced, and the market need is met.

Description

technical field [0001] The invention relates to the technology in the field of bottle cap production and processing, in particular to a molding method for compression-molded bottle caps. Background technique [0002] Since the mid-1990s, Coca-Cola’s PET bottled beverages have used plastic anti-theft caps instead of aluminum caps, thus pushing plastic anti-theft caps to the front desk of beverage packaging and starting the mass production and application of plastic anti-theft caps. [0003] Since the advent of the plastic cover, it is popular for its low price, easy to use, safety, environmental protection and other characteristics. Widely used in the packaging of pharmaceutical, chemical, seasoning, food, beverage and other industries. [0004] According to the production process, the production of bottle caps traditionally uses injection molding mechanism caps. The production process of the injection molding cap is that the suction machine sucks the mixed material into th...
