Abstract

The invention provides a manufacture method of a glass door and a glass door. The manufacture method of the glass door comprises the following steps: Step 1, a glass plate is provided with an intake and exhaust auxiliary hole, and a glass door is put into an injection mold; Step 2, a plastic material is poured into the injection mold to form a plastic blank on the glass plate; Step 3, a gas needle is inserted into the intake and exhaust auxiliary hole so as to pour high pressure gas into the plastic blank, a cavity is formed inside the plastic blank under the action of high pressure gas, and the outer wall of the plastic blank extrudes to lean against the cavity wall of the injection mold so as to form a hollow plastic handle on the glass plate; and Step 4, the intake and exhaust auxiliary hole is sealed, and the hollow plastic handle undergoes pressure-maintaining treatment. According to the invention, thickness of the plastic handle is increased, structural strength is raised, and the appearance effect and users' hand feeling are optimized.

Description

technical field [0001] The invention relates to a glass door, in particular to a method for manufacturing a glass door and the glass door. Background technique [0002] Currently, glass doors are widely used in refrigeration equipment to enhance aesthetics and visibility. And the glass door is usually provided with a handle for the user to push and pull the switch door. The handle on the glass door usually has two forms: one is the handle formed by injection molding on the glass plate through the injection molding process, and the other is the handle connected to the glass plate through screws and other joints alone. In order to realize the appearance of the glass door as an integral structure, handles injection molded on the glass plate are widely used. Then, affected by factors such as the injection molding process and plastic thermal expansion and contraction, the thickness of the injection handle is narrow to avoid the process of injection molding. Shrinkage marks appe...
