High frequency welding three-dimensional mold
The utility model relates to a kind of mould with thermal source or high frequency welding.
Existing high frequency welding mould is plane mould, is arranged between the upper and lower flat board of high frequency board.Mainly contain three kinds of forms: a kind ofly be: die frame is located on the upper flat plate, and following flat board is flat; A kind ofly be: die frame is located at down on the flat board, and upper flat plate is flat; Also have and a kind ofly be: mould is movable, then dull and stereotyped up and down be flat.This shows, during traditional high frequency mould welding material, be flat always one side is arranged, thereby make the high frequency welding be confined to the welding on plane, that is to say that no matter the two-layer or two-layer above material of required welding, face of weld all belongs on the plane.Though the welding of PVC material has not at grade, because of the percentage elongation of PVC material is bigger, by specific mould and method (volume mould), can make the material of Different Plane make face of weld at grade by distortion.But if the welding Different Plane, that percentage elongation is very little and weld bond is on same plane and straight line, traditional high frequency mould is difficult to realize, generally can only taking curve is that the mode of multi-line section is processed, and reduced process velocity greatly.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can carry out the curved surface welding of material, the novel solid mould that process velocity is fast, precision is high easily.
The purpose of this utility model realizes according to such design concept: the true form of finished product after the analysis welding, its each plane exploded view draws, utilize the principle of curve upright projection for straight line, opposite two the welding curve projections of direction on same curved surface, again curved surface is divided into two parts up and down, is designed to the novel solid mould of forming by upper die and lower die; Upper die and lower die include base and face of weld, and its patrix face of weld is an inner sunken face, and the counterdie face of weld is the upper convex surface that matches with the patrix face of weld.
Patrix face of weld described in the utility model can be a space curved surface, is that the vertical cambered surface by horizontal cambered surface of length direction and width constitutes; The face of weld of counterdie is the space curved surface that coincide with the patrix face of weld.
Patrix face of weld described in the utility model is provided with some weld bonds.
Owing to take said structure, the face of weld that the utility model utilization coincide up and down, welding Different Plane easily, that percentage elongation is very little and weld bond be at grade material not.Its welding mode is the curved surface welding, can effectively improve process velocity and machining accuracy.The radian of face of weld of the present utility model can be according to the true form design of finished product after the desire welding.
Reaching embodiment in conjunction with the accompanying drawings is further described the utility model:
Accompanying drawing 1, the utility model example structure schematic diagram;
Accompanying drawing 2, the utility model embodiment patrix structural representation;
Accompanying drawing 3, the utility model embodiment patrix A-A profile;
Accompanying drawing 4, the utility model embodiment patrix partial enlarged drawing;
Accompanying drawing 5, the utility model embodiment patrix C are to structural representation;
Accompanying drawing 6, the utility model embodiment counterdie structural representation;
Accompanying drawing 7, the utility model embodiment counterdie D are to structural representation;
Accompanying drawing 8, the utility model embodiment counterdie E are to structural representation;
Embodiment, shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, accompanying drawing 6, accompanying drawing 7, accompanying drawing 8, the utility model is made up of patrix (1) and counterdie (2); Patrix (1), counterdie (2) patrix include base (14) (24) and face of weld (11) (21), its patrix (1) face of weld (11) is the indent space curved surface, be by vertical cambered surface (13) formation of horizontal cambered surface of length direction (12) and width, on face of weld (11), be provided with 4 weld bonds (15); The face of weld (21) of counterdie (2) is the epirelief space curved surface that the face of weld (11) with patrix (1) matches, and is vertical cambered surface (23) formation by horizontal cambered surface of length direction (22) and width.
Patrix (1), counterdie (2) with three-dimensional mold during use are separately fixed on the upper and lower flat board of high frequency board.
