Embodiment 1

[0035] Such as Figure 2-3 As shown, the silicone injection mold includes a positioning body 3 for setting the glass bottle 100, and a first side parting mold for encapsulating the glass bottle 100 from the outer periphery of the side wall of the glass bottle 100 is arranged on both sides of the positioning body 3 111 and the second side parting mold 112 , an end mold 12 for encapsulating the glass bottle 100 towards the outer bottom wall of the glass bottle 100 is provided at the end of the positioning body 3 . Wherein, the first side parting mold 111, the second side parting mold 112 and the end part mold 12 form the inner injection molding space 2 after the joint molds are seamlessly connected. At this time, the positioning body 3 is located at the center of the injection molding space 2. And after the glass bottle 100 is set on the positioning body 3 for positioning, the outer wall of the glass bottle 100 has a stable contact with the inner wall of the first side parting m...

Embodiment 2

[0049] Dip-coat the surface of the glass bottle 100 in the glue solution, avoid dipping the external thread of the glass bottle 100, put the dip-coated glass bottle 100 into an oven and bake at 100°C for 20 minutes to form a thick layer on the outside of the glass bottle 100. 0.07mm glue coating, and use a clean cloth to wipe off the glass bottle 100 forming the glue coating or blow it clean; after the protective shell 4 and the protective ring are set on the glass bottle 100, the glass bottle 100 is set on the positioning body 3. Make the first side parting mold 111, the second side parting mold 112 and the end part mold 12 seamlessly connected to realize mold closing, and preheat. The preheating temperature is 130°C, keeping the temperature of the silicone injection mold At a temperature of 130°C, through the two injection ports 123 of the silicone injection mold, inject liquid silicone into the silicone injection mold from both sides toward the bends of the side wall and the...

Embodiment 3

[0051] Dip-coat the surface of the glass bottle 100 in the glue solution, avoid dipping the external thread of the glass bottle 100, put the dip-coated glass bottle 100 into an oven and bake at 125°C for 45 minutes to form a thick layer on the outside of the glass bottle 100. 0.1mm glue coating, and use a clean cloth to clean the glass bottle 100 that has formed the glue coating or blow it clean; after the protective shell 4 and the protective ring are set on the glass bottle 100, the glass bottle 100 is set on the positioning body 3. Make the first side parting mold 111, the second side parting mold 112 and the end part mold 12 seamlessly connected to realize mold closing, and preheat. The preheating temperature is 145°C, keeping the temperature of the silicone injection mold At a temperature of 145°C, through the two injection ports 123 of the silicone injection mold, inject liquid silicone into the silicone injection mold from both sides toward the bends of the side wall and...

Abstract

The invention relates to a technological method for forming silica gel layers on the surfaces of glass bottles by means of injection molding. The technological method includes carrying out dip-coatingon the glass bottles in glue solution, heating the glass bottles and forming glue coatings on the outer walls of the glass bottles; carrying out injection molding on liquid silica gel in preheated silica gel injection molds with the glass bottles and forming the silica gel layers outside the glue coatings of the glass bottles by means of injection molding. The technological method has the advantages that the glass bottles are adhered in liquid silica gel injection modes, the surfaces of the glass bottles do not need to be sprayed, only dip-coating needs to be carried out on the surfaces of the glass bottles in the glue solution, accordingly, silica gel can be effectively adhered, and the glass bottles are explosion-proof and drop-resistant; broken glass can be prevented from being scattered around even after the glass bottles are smashed, and accordingly excellent safety protection effects can be realized; bodies of the glass bottles are formed at one step by means of silica gel injection molding, accordingly, products are high in yield, and firm silica gel and glass adhesion effects can be realized; the surfaces of the products feel soft, good service effects can be realized, andthe products are excellent in user experience.

Description

technical field [0001] The invention relates to the technical field of injection molding technology, in particular to a process method for forming a silica gel layer by injection molding on the surface of a glass bottle. Background technique [0002] Glass bottle is generally used as a container for milk or tea and other beverages. Its characteristics are that the container does not contain bisphenol A, easy to clean, good transparency, high hardness, high temperature resistance, high temperature sterilization without release of toxic substances, but easy to drop broken, causing easy injury. Although in the prior art there is also a protective cover on the outside of the glass bottle to prevent falling, the anti-fall effect is not good, and the phenomenon of falling is still prone to occur, and it is inconvenient to use and the user experience is poor. Contents of the invention [0003] The object of the present invention is to provide a process method for forming a silic...
