Abstract
The present invention discloses a circular arc cabinet opening heat forming method and a special mould thereof. The method comprises the following manufacture steps that any two adjacent edge frames for forming a cabinet opening are welded to a primary edge angle part which is provided with right angle type internal edge angles and external edge angles at a butt joint position; one primary edge angle part is put in a mould pattern for heating and softening; a corresponding circular arc section is formed by extruding sections formed by the internal edge angles and the external edge angles; after the circular arc section is cooled and retrograded, a finished product grade edge angle part of which the internal edge angles and the external edge angles are circular arc angles is obtained. The special mould comprises two modules, wherein one module is provided with an inner circular arc pattern, and the other module is provided with an outer circular arc pattern. The modules are provided with electric heating pipes. The mode of processing circular arc cabinet openings is simple, and the integration of the circular arc edge angle part is strong.
Description
Technical field
The present invention relates to the thermoforming process of circular arc cabinet mouth in a kind of household freezer.
Background technology
Present refrigerator extrusion profile cabinet mouth (the particularly cabinet mouth of top-opening type refrigerator) the formed corner of adjacent frame joint portion, outer corners has two kinds of forms in it, one is the right angle mode, advantage is that the simple cost of cabinet opening processing process is low, shortcoming is an evaporimeter processing technology complexity, because the interior outer corners of four corner portions of cabinet mouth is the right angle, four corners of cabinet inner bag also are necessary for the right angle mode, so evaporimeter need take eccentric orthodrome transition just can prevent to cause the body gross distortion because of the right angle transition when being arranged into the inner bag edge, cause evaporimeter and inner bag edge applying sealing technology complicated and seal unreliablely simultaneously, increase the evaporator material cost; Another kind is the arc chord angle mode, this arc chord angle mode is that bonding small-sized injection moulding circular arc corner fittings forms on the basis of above-mentioned right angle mode, though it helps evaporimeter moulding process and evaporimeter at cabinet bicker portion sealing technology, it is more effective that evaporimeter and inner bag are fitted, refrigerating capacity is guaranteed, but the processing mode complexity of this inside and outside fillet, cost is higher, and associative perception is relatively poor.
Summary of the invention
Task of the present invention provides a kind of circular arc cabinet mouth thermoforming process, the cabinet mouth that it is produced, and the interior outer corners of adjacent frame joint corner portion is an arc chord angle, and its processing mode is simple, and associative perception is stronger.
Its technical solution is:
A kind of circular arc cabinet mouth thermoforming process, its making step is:
Wherein two adjacent frames that a will form the cabinet mouth weld the primary edge bight that is formed with outer corners in the right-angle type at joint;
B puts into mould with an above-mentioned primary edge bight and carries out thermoplastic, and outer corners formation section in it is pushed the corresponding arc section of formation;
Withdraw from after the c cooling, outer corners is the one-tenth grade corner portion of arc chord angle in promptly obtaining.
Among the above-mentioned steps b, also can comprise extruding to the arc section upper and lower end face.
Among the above-mentioned steps b, extruding arc section upper and lower end face makes end face form burnishing surface.
Processing mode of the present invention is simple, and the cabinet mouth associative perception of producing is stronger.
Description of drawings
Fig. 1 is a kind of embodiment master of circular arc cabinet mouth thermoforming process particular manufacturing craft TV structure schematic diagram.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is the A-A sectional structure schematic diagram of Fig. 1.
The specific embodiment
A kind of embodiment below in conjunction with particular manufacturing craft describes circular arc cabinet mouth thermoforming process of the present invention:
Referring to Fig. 1, Fig. 2, Fig. 3, particular manufacturing craft of the present invention comprises patrix 1, counterdie 2 and pressing mold 3, patrix 1 has the apperance that forms the arc section external arc, counterdie 2 has the apperance that forms circular arc in the arc section, the bottom of counterdie 2 is provided with the holding table top, pressing mold 3 is positioned at the top of patrix 1 and counterdie 2, on counterdie 2, be provided with two electric heating tubes 6, two electric heating tubes become the orientation setting of a corresponding frame separately, the bottom surface of pressing mold 3 is the plane, described counterdie 2 is fixed on the workbench 10, patrix 1 is moved forward and backward along the guide rail 5 that is fixed on the workbench 10 by cylinder 4 pullings, pressing mold 3 is fixing by the support 11 that is fixed on the workbench 10, and is moved up and down by cylinder 7 pullings, and the both sides of pressing mold 3 are respectively arranged with the binder hinge that driven by cylinder 89.
Its course of work roughly is, wherein two adjacent frames that at first will form the cabinet mouth form the primary edge bight in the joint welding, there is outer corners in the right-angle type in this primary edge bight, the primary edge bight is placed on the holding table top of counterdie 2, promoting patrix 1 clamps the primary edge bight, heating tube on the counterdie 2 heats two frame sections and the joint in primary edge bight then, make it softening, utilize cylinder 4 to continue to promote patrix 1 again, make the circular arc apperance of patrix 1 and counterdie 2 cooperate extruding to clamp, form arc section, pressing mold 3 compresses arc section downwards then, to flatten because of the end face deformation that thermal stress and tensile stress cause, the one-tenth grade corner portion that an interior outer corners that promptly obtains the cabinet mouth is arc chord angle is withdrawed from cooling; By that analogy, choose two adjacent frames again and form another primary edge bight in the joint welding, other three arc chord angle corner portions that adopting uses the same method makes the mouth that offers for sale form circular arc cabinet mouth at last.
Also can adopt following method to make circular arc cabinet mouth, earlier four frames are welded into right angle cabinet mouth, then one of them primary edge bight of cabinet mouth is placed on the counterdie 2, promoting patrix 1 clamps this corner portion, heating tube on the counterdie 2 heats two frame sections and the joint of this corner portion then, make it softening, utilize cylinder 4 to continue to promote patrix 1 again, make the circular arc apperance of patrix 1 and counterdie 2 cooperate extruding to clamp, form arc section, pressing mold 3 compresses arc section downwards then, to the deformation on end face flatten because of thermal stress and tensile stress, form the one-tenth grade corner portion that an interior outer corners is arc chord angle, all the other corner portions adopt to use the same method and are made into, and form circular arc cabinet mouth at last.
In the above-mentioned embodiment, electric heating tube also can be arranged on the patrix, or on upper die and lower die electric heating tube is set simultaneously.
In the above-mentioned embodiment, the working face of pressing mold (bottom surface) can have other multiple variations as required except that the plane.
Circular arc cabinet mouth thermoforming process of the present invention is not limited to and uses above-mentioned particular manufacturing craft.
