Abstract
The invention discloses a quick-freezing tray mounting structure of a freezing chamber of an air-cooled refrigerator and a forming method thereof, wherein the quick-freezing tray mounting structure of the freezing chamber of the air-cooled refrigerator comprises a tray and a tray embedded plate formed in the tray, positioning holes are respectively arranged at four corners of the tray embedded plate, and exhaust holes are formed in the bottom of the tray. The invention realizes the structure that metal is pre-embedded in the plastic piece, and can quickly freeze food put in the tray of the freezing chamber.
Description
The technical field is as follows:
the invention relates to a quick-freezing tray mounting structure of a freezing chamber of an air-cooled refrigerator and a forming method thereof, belonging to the technical field of refrigerators.
Background art:
at present, a freezing tray of a freezing chamber of an air-cooled refrigerator is a plastic piece, the heat conductivity of the plastic piece is slow, food placed in the freezing tray can be frozen in a long time, and the heat conduction uniformity of the plastic piece is poor.
Therefore, there is a need to improve the prior art to overcome the deficiencies of the prior art.
The invention content is as follows:
the invention provides a quick-freezing tray mounting structure of a freezing chamber of an air-cooled refrigerator and a forming method thereof, which can quickly freeze food put in the tray of the freezing chamber.
The invention adopts the following technical scheme: the utility model provides an air-cooled refrigerator freezer quick-freeze tray mounting structure, includes tray and the pre-buried board of tray of shaping in the tray four corners of the pre-buried board of tray are equipped with the locating hole respectively, the hole of exhausting is seted up to the bottom of tray.
Further, the material of the pre-buried plate of the tray is an aluminum plate, and the thickness of the pre-buried plate is 0.5 mm.
Further, the material of the tray is HIPS, the bottom of the tray is 2mm in thickness, and the total thickness of the tray is 3 mm.
The invention also adopts the following technical scheme: a method for forming a quick-freezing tray mounting structure of a freezing chamber of an air-cooled refrigerator comprises the following steps:
the method comprises the following steps: positioning four positioning holes of the tray embedded plate through ejector rods on a rear die of the die;
step two: and (3) closing the front mold and the rear mold, injecting raw materials into the mold, maintaining the pressure, cooling, opening the mold, and determining a product to finally form the tray with the tray embedded plate.
The invention has the following beneficial effects: the quick-freezing tray mounting structure of the freezing chamber of the air-cooled refrigerator and the forming method thereof realize the structure that metal is pre-embedded in a plastic piece, and can quickly freeze food put in the tray of the freezing chamber.

The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
The quick-freezing tray mounting structure of the freezing chamber of the air-cooled refrigerator comprises a tray 1 and a tray embedded plate 2 formed in the tray 1, wherein the tray embedded plate 2 is made of an aluminum plate and is 0.5mm thick, the tray 1 is made of HIPS (high impact polystyrene), the bottom of the tray is 2mm thick, and the total thickness of the tray is 3 mm. In order to fix the tray embedded plate 2 in the grinding tool in the forming process, positioning holes 3 are respectively arranged at four corners of the tray embedded plate 2, and the positioning holes 3 are arranged on ejector rods of the die for positioning.
The invention relates to a forming method of a quick-freezing tray mounting structure of a freezing chamber of an air-cooled refrigerator, which comprises the following steps:
the method comprises the following steps: positioning four positioning holes 3 of the tray embedded plate 2 through ejector rods on a rear die of the die;
step two: and (3) closing the front mold and the rear mold, injecting raw materials into the mold, maintaining the pressure, cooling, opening the mold, and determining a product to finally form the tray with the tray embedded plate.
The structure that metal is pre-embedded in the plastic part is realized, and as a further improvement of the structure, the vent holes are formed in the bottom of the tray, so that gas in the mold can be discharged in time, and the phenomenon of bulging when the pre-embedded plate of the tray is formed is avoided.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
