Embodiment 1

[0026] As shown in Figures 1 to 3, a rectangular refrigerator box frame includes a frame body 1 composed of a front frame bar 11, a rear frame bar 12, a left frame bar 13 and a right frame bar 14. The front frame bar 11, The rear frame strip 12, the left frame strip 13 and the right frame strip 14 are four plastic extruded strips with the same cross-section. The two ends of each extruded strip are provided with bevels 4, and the four extruded strips pass through the two ends of the extruded strip. The position of the bevel 4 is butt-jointed to form a frame body 1 after being welded. The extruded strip is made of plastic material HPVC. The radius is 25 mm and the outer corner 3 has a radius of 4 mm. The front frame bar 11, the rear frame bar 12, the left frame bar 13 and the right frame bar 14 are all provided with a step surface 5, and the edge of the step surface 5 is provided with a protruding rib 6, the rib bar The height of 6 is 1 millimeter, and this rib 6 is used as the...

Embodiment 2

[0030] The structure and manufacturing method of this embodiment are basically the same as those of Embodiment 1. The structural differences are: as shown in Figures 4 to 6, the front frame bar 11, the rear frame bar 12, the left frame bar 13 and the right frame bar 14 There are three steps on the upper surface, and a protruding rib 6 is provided at the edge of each step, and the rib 6 is used as a guide bar for the glass door with a built-in plastic frame to facilitate the sliding of the glass door frame.

[0031] The difference in its manufacturing method is that extruding an extruded strip with exactly the same cross-section and three stepped surfaces on the cross-section through an extrusion die, with ribs 6 protruding from the edge of each stepped surface, and the ribs 6 The height is 1 mm, and the rib 6 is a guide bar for the glass door with a built-in plastic frame, so as to facilitate the sliding of the glass door.

Abstract

The invention provides a rectangular refrigerator box frame and its manufacture method, the rectangular refrigerator box frame includes the frame body(1) which is composed of the front frame strip(11), the frame strip (12), the left frame strip (13) and the right frame strip (14), the states frame strips is made of the four same section plastics extruding strips, the each extruding strip beginnings and ends is equipped with the drift angle (4), the four extruding strip after the drift angle (4) of two terminal part butt-joint welds form the frame body (1); the interior angle(2) and the outer angle (3) of the four side angle in the rectangular refrigerator box frame body all process rotundity. The refrigerator box frame has low production cost, the strong interchange ability, the simple structure, the small assembly difficulty, the artistic contour, the high intensity of low temperature anti-impact, is not easy cracked under -10 deg-30 deg condition.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a horizontal rectangular refrigerator frame and a manufacturing method thereof. Background technique [0002] In the prior art, the box frame used in the horizontal freezer generally has two structures, one is the box frame formed by integral injection molding, and the other is the box frame spliced ​​by HPVC or aluminum alloy extrusion parts and injection molded parts. The disadvantages of the integral injection molding box frame are high mold cost, no interchangeability, low low temperature impact strength, and easy to crack under the condition of -10°C ~ -30°C, especially the cost of the integral injection molding box frame mold for large refrigerators is extremely high , even limited by the processing capacity of the equipment and cannot be realized; in addition, the joints of the box frame spliced ​​by HPVC extrusion parts and injection molded parts are large and difficult to as...
