Abstract

The present invention relates to a die set for making the net by adopting stereo-forming process and its method. Said die set mainly possesses a base die and a top die, they possess mutually opposite half-round die cavity respectively, and these half-round die cavities can be combined into a long round die cavity, and two ends of the base die and top die are respectively equipped with end die. The base die and top die can be matched with its respective end die to form concave-convex matched die cavity respectively, so that one end of the semifinished product can be formed into round formed portion by means of die cavity, and the semifinished product also can be formed into the contracted form in the dies-combined narrower place, then the contracted form can be made into conical formed portion by means of extruction of end die so as to obtain the invented stereo product.

Description

The mould of stereo formation net-making and method

The present invention relates to a kind of mould and method of stereo formation net-making, its mould mainly has the basic mode and the backform of a mutual involutory die cavity, and its base, backform two ends are provided with the end mould relatively, by base, the involutory clipping of backform, raw material is made semi-finished product with embryo, the abutting end mould is made expansion shape or collapsed shape to the semi-finished product end again, and makes the semi-finished product part of base, backform inside be affixed on the mould intracavity wall moulding more reliably, directly semi-finished product is molded uneven three-dimensional finished product.

For solid netted ornament structure, it is to make solid netted ornament structure, such mode with manual method on a dictyosome structure mostly, not only labor intensive more makes the expense cost of manufacturing improve relatively, and whole manufacturing efficient is limited especially, therefore, need improve.

Based on above reason, for the process that makes its moulding can be finished with mould cheaply, and improve shaping speed, improve Forming Quality, developed a kind of mould and method that meets a kind of stereo formation net-making of the present invention of above-mentioned condition.

Below in conjunction with accompanying drawing preferred embodiment is elaborated:

As Fig. 1,2, shown in 3, reshaper 30 of the present invention mainly has a board 31, the centre of board 31 is fixed a basic mode 32 by a die holder 320, place, basic mode 32 two ends is provided with an end mould 33 that can move horizontally in addition relatively, and be provided with a backform 34 in addition in the top of basic mode 32, and its end mould 33 is individually fixed in sliding slide 330 of striding on the board 31 with backform 34,340, slide 330,340 respectively by a cylinder pressure 331,341 promote, and its base,

backform

32,34 are provided with the relative die cavity of semicircle spill 321 relatively, 342, and its die cavity 321, but 342 end abutting end moulds 33 are set as the end die cavity 332 that enlarges shape, 343, end mould 33 then is provided with end mould portion 332 relatively, makes the cooperation of unitary mould mold finished product by designing requirement reliably.

Cooperate mould improvement the making flow process as shown in the figure, and the flow process of its moulding in kind is as shown in Figure 3, its key step has:

Charging 10: the material metal plate 20 with suitable thickness, metallic character lies against on the workbench of counterdie, and is connected to quantitative automatic feeding with automatic feeding;

Go into mould 11: will be prefabricated into the mould of plane net material unfoldable shape die cavity, and be installed on patrix, quantitatively being fed in the mould of compounding ingredient located;

Punch forming 12: behind above-mentioned material, the mould location, fall according to operating automatically to dash, stamping material, when cooperating charging for the second time, patrix is done a left side or right fixedly displacement, goes out into a complete poroid dictyosome 21, and punching press and so forth is shifted;

Cut off 13: make according to above-mentioned punching press, make net material length reach a preseting length,, once dash, dictyosome 21 is ruptured automatically at the end of certain suitable length with the upper punch number of times control that falls;

Roll tubular 14: the unit length dictyosome 21 after will cutting off, weld fixedly two ends by rolling and passing through, and become hollow barrel-type semi-finished product 22;

Integer 15: cooperate the reshaper 30 shown in Fig. 3,4,5, make shape formation one expansion shape or the contraction-like forming part 230 of the end of semi-finished product 22 according to mould;

Finish 16: can mold finished product 23 by forming part 230.

Its course of action is, basic mode 32 and backform 34 matched moulds, then aforesaid tubular semi-finished product 22 levels are placed base, backform 32, a circular die cavity 321 of 34,342 and one has between the end mould 33 of round nose mould portion 332, extruding by this end mould 33, as shown in Figure 5, make semi-finished product 22 1 ends according to die cavity 322,343,332 form the many forming parts 23 of a spherical shape, as shown in Figure 6, and the other end is then through base,

backform

32,34 involutory narrower places become one contraction-like, another group end mould 33 are advanced again, make the end of the straight tube of this former one-tenth, mold the taper forming part 24 of expansion form,, move back mould again to make finished product 25.

Also reshaper 30 structures can be set as shown in Figure 7, has a motionless basic mode 32 on its board 31, and the other end is provided with the end mould 33 of slip, to carry out the design of monolateral expansion form, make plastic kettle body 26 finished products that go out kettle shape entity as shown in Figure 8 of whole structure, also can be as shown in Figure 9, form Chinese kettle shape design, also can be the vase design, to reach the purpose of rapid shaping as shown in figure 10.

By above-mentioned mould, cooperate its manufacture method, make the present invention have following advantage, for example:

1. Forming Quality keeps high level: cooperate Mould design to make dictyosome structure straight forming cylindraceous, make that its profile is partly unlikely to be subjected to any destruction, can keep certain level, structure is more strong, shape after the follow-up integer of more unlikely destruction is guaranteed the quality of integral construction.

2. the cost of moulding is low: it molds the stereo concave-convex shape and molds cancellated mould and is divided into two partly, the employed mould cavity design of its each moulding is very simplified, be respectively the stereo concave-convex die cavity, and the intensive relative profile of tooth on plane, the design respectively of its mould can reduce whole expense relatively, reduce the cost of integral manufacturing relatively, meet economic principle.

3. moulding while structure does not have the phenomenon of destruction: when it molds the dictyosome structure, the unlikely violent stay bolt power influence that is subjected to the three-dimensional shape moulding of dictyosome, destroy and produce, and when the three-dimensional shape moulding, each part of its dictyosome is when three-dimensional integer, during its local pressure, can be by the mutual stay bolt of dictyosome structure of integral body, really the stay bolt power of part is disperseed, do not have the phenomenon of any destruction, the quality after the maintenance moulding.

And the design of unitary mould, the three-dimensional mold structure can be given complanation in addition, be about to desire the three-dimensional die cavity of moulding, be combined into one with the die cavity of moulding dictyosome, be that Mould design only has base,

backform

32,34 setting, its die cavity 321,342 become a concavo-convex cooperation merely, the form of its concavo-convex cooperation, become a fenestral fabric and form the just cooperation of rolling shape, make a metallic plate 20 straight formings go out to have the dictyosome structure of rough pattern, roll finished product after being cut off again, welding fabrication goes out cylindric space network, the dictyosome finished product of forming stereo shape, so the mould design still can have all above-mentioned function.

In sum, the present invention can reach above-mentioned all function really.
