Description
Technical Field
The invention relates to a foaming mould for a side-by-side refrigerator door body, in particular to a long-side barrier strip large-stroke translation mechanism for the foaming mould for the side-by-side refrigerator door body, and belongs to the technical field of foaming moulds.
Background
The refrigerator can be divided into two doors, three doors, four doors, multiple doors, opposite doors and the like according to the door structure, each door is internally provided with different box inner containers and door inner containers to form independent and airtight areas, foaming materials are used for filling between the areas to play roles of heat insulation and heat preservation, and the temperature in each area can be different for storing different food materials. The refrigerator door is opened by the rotation shafts on the upper and lower sides of one side of the door, the other side of the door is pulled outwards by hand to grasp the refrigerator door, and the refrigerator door can be rotated and opened around the two rotation shafts. In order to facilitate the exertion, a door handle is generally arranged at the door edge of the door, and three modes are adopted for the door handle: 1. the aluminum alloy or stainless steel handle is independently arranged on the front surface of the door opening edge; 2. when the door shell is formed, a convex edge is formed on the door opening edge; 3. the handle is hidden. The first handle affects the overall appearance and affects the usage space; the second handle causes the door opening edge of the refrigerator door to be wider than the refrigerator body, so that the overall appearance of the refrigerator is affected, and the refrigerator side with the hidden handle solves the problems; a third type of hidden handle refrigerator is currently popular.
For the foaming mould of the refrigerator door, four baffle strips are arranged around the refrigerator door body, two sides of the baffle strips are fixed, and the other two doors can rotate around a hinge shaft arranged at the bottom for a certain angle, so that the door body can be conveniently taken and placed. When foaming, the front face of the door body is downward, for the door body using the hidden handle, the hidden handle part is formed by a concave space, and on the side face of the door body, if the foaming is carried out without a lining block, the side barrier is deformed, and a turnover mechanism is adopted, if a concave lining mould is fixed on the side barrier, the lining block interferes with the door body when the mould is closed and opened, so that the lining block cannot be fixed on the side barrier.
Aiming at the problems, for some home appliance manufacturing enterprises with low requirements on product quality, a foam mold is not supported by a concave part, and the home appliance manufacturing enterprises naturally deform after foaming; however, for some home appliance manufacturing enterprises with high requirements on product quality, the concave part is provided with a foaming mould to form a process pad, the material of the process pad is aluminum alloy or wood, the process pad is placed in the concave part and fixed on the door body by using an adhesive tape before the door body is foamed, and the process pad is taken down after the foaming is finished.
For the two-door, three-door and multi-door refrigerators, the height of the refrigerator door is smaller and is generally between 320 and 900 mm, the length of the concave part is shorter, the pad of the general process is smaller, the deformation is small, the weight is light, and the foaming process can ensure the product quality besides increasing the cost of manpower and working procedures. However, for a side-by-side refrigerator, the height of the door body is generally about 1800 mm, the inward concave part is long in process lining, the weight of the process lining made of aluminum alloy materials is heavy, the taking and placing are inconvenient, the adhesive tape is difficult to fix, and if the adhesive tape is easy to deform by using wood.
Therefore, how to develop a door handle hidden door body foaming mold for a side-by-side combination refrigerator solves the problem of manual placement of a handle process pad, reduces the collision scratch of a door body surface person, improves the door body surface quality, and becomes a problem which needs to be solved currently.
