In-mold decoration machine for producing tool hand and in-mold decoration process units
Technical field
The utility model relates to a kind of in-mold decoration machine for producing tool hand and in-mold decoration process units.
Background technology
Decoration technique inside mold (hereinafter to be referred as IMD technology) is the technology on moulding surface that film or pattern are arranged in injection moulding process.IMD technology be take injection mo(u)lding as support, realize injection mo(u)lding and decoration integrated, once complete, can make various special-effect again, as: metallic mirror surface or delustring face, metal wire-drawing line, back of the body light transmission, sags and crests line etc., have ornamentally and functional, be widely used on the panel of automobile, communication, electronics, electrical equipment, instrument, instrument, integrate ornamental and functional.In IMD technology, very important to the pretreatment of film before injection moulding.Pretreatment carries out the pre-heat treatment to film, makes film soften or make the printed patterns on film more easily separated with film; Heating can also be removed the moisture of the pattern on film or film, thereby guarantees to reduce splashing of ink when injection mo(u)lding, improves the closely sealed of injection molding material and ink, strengthens the adhesive force of ink, avoids the cracking of ink or comes off, and guarantees the transfer quality of ink.
In conventional art, for the pre-heat treatment of film, generally by independent roasting plant, undertaken, outside injection mold, add roasting plant, in film is transferred to mould before, by roasting plant, carry out the pre-heat treatment.The shortcoming of above-mentioned roasting plant, the one, complex structure, because needs arrange independent roasting plant, and need to be used in conjunction with in-mold decoration injection mold, has therefore increased the complexity of integral production device.The 2nd, production efficiency is low, due to the independent preheating of needs, transfers in mould after preheating, and preheating and transmission all need the time, therefore cause production process length consuming time, and efficiency is low.The 3rd, poor product quality, outside independent mould, after film baking, to transferring to, in mould, carry out transfer printing and also need a period of time, in transmitting procedure, film can be cooling, if environment temperature is low while producing, may cause film completely cooling, pre-heat effect variation, product rejection rate reaches more than 10%.The 5th, while needing preheating size larger due to film, like this dimensional requirement of roasting plant is also further improved, the roasting plant that causes being independent of outside mould is oversize, and the space taking is also just more, from aspects such as the installation of equipment, production costs, to production, has brought difficulty.Existing in-mold decoration production mould, pickup and film heating carry out respectively, length consuming time, efficiency is low.

Preferably, described male model upper end is also provided with film fixing device; Film roll is arranged on described film fixing device rotationally, and emits film after the rotation of described film roll, makes film between described male model and master mold.
Preferably, also comprise film drawing device, described film drawing device is used for pulling film, makes film between male model and master mold, and described film drawing device is arranged on male model below.
Preferably, described mechanical arm is arranged at production mould top in described mould; When described mechanical arm moves between described male model and master mold, described heater is relative with described male model; Described grabbing device is relative with described master mold.
Preferably, described grabbing device comprises at least one vacuum cup; Described vacuum cup is communicated with vavuum pump.
Preferably, described heater comprises at least one electric boiling plate.
Preferably, also comprise host computer; Described host computer is used for controlling described in-mold decoration production mould, mechanical arm, heater and grabbing device work.
In-mold decoration machine for producing tool hand and in-mold decoration process units in the utility model, the positive grabbing device of mechanical arm is when taking-up is injection-molded finished, the heater heating film at the back side, the pre-hotsync of pickup and film is carried out, and has saved injection moulding production process and time.In the time of pickup, film is carried out to preheating, and can be to entering the film heating in mold cavity, after pickup, film can be placed immediately and enter in mold cavity, and between preheating and placement, not free interval, can not make film cooling, pre-heat effect is good, and product rejection rate is reduced to below 5% by 10%.The utility model installs heater additional at the mechanical arm back side, without heater is set separately, simple in structure, save production space and production cost.Grabbing device adopts vacuum cup to capture, and has avoided the problem of mechanical gripper damage injection-molded item in traditional handicraft, has protected finished product outward appearance, has improved end product quality.Use the utility model, can improve and come into force efficiency more than one times.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
Embodiment 1
As shown in Figure 1, Figure 2 and Figure 3, in-mold decoration process units, comprises in-mold decoration production mould, mechanical arm 3, grabbing device 4 and heater 5.In-mold decoration production mould comprises master mold 1 and movable male model 2.Injection moulding when master mold 1 and male model 2 matched moulds, separates after injection moulding completes.Machinery arm 3 is arranged on master mold 1 and male model 2 tops movingly.Machinery arm 3 is by power set (not shown) actuation movement.Power set can adopt motor, and by transmission of power, give mechanical arm 3 by transmission device.When master mold 1 and male model 2 separate, mechanical arm 3 is moveable between master mold 1 and male model 2.Grabbing device 4 is three vacuum cups, is arranged on mechanical arm 3 fronts.Vacuum cup is communicated with vavuum pump (not shown).Heater 5 is electric boiling plate, is arranged on mechanical arm 3 back sides.
Male model 2 upper ends are also provided with film fixing device 6.Film fixing device 6 comprises and is provided with axle 61.Film roll 7 is sleeved on axle 61 rotationally.Male model 2 belows are provided with film drawing device (not shown), and film drawing device pulls film one end, and film roll 7 is rotated.Film roll 7 rotates can emit film, utilizes film drawing device to pull, and makes film between male model 2 and master mold 1.Film drawing device can adopt rotating rotating shaft.Film end is wrapped in rotating shaft, and rotating shaft can pull film to move while rotating.
The utility model is also provided with host computer; Host computer is used for controlling described in-mold decoration production mould, mechanical arm 3, heater 5 and grabbing device 4 work.
During production, mould die sinking, male model 2 master molds 1 are separately.The work of PC control film drawing device, is pulled to film between master mold 1 and male model 2.PC control machinery arm 3 moves between master mold 1 and male model 2.5 work of PC control heater, the film of preheating between master mold 1 and male model 2, makes film softening.After preheating completes, mechanical arm 3 rises, male model 2 and master mold 1 matched moulds, and film enters in die cavity, injection moulding.After matched moulds, film does not cut off along its length.After injection moulding completes, die sinking, film drawing device continues to pull film, makes next section of film between male model 2 and master mold 1.In the time of membrane, mechanical arm 3 drops between male model 2 and master mold 1.When machinery arm 3 drops to the position that is applicable to pickup, membrane has moved.Now, grabbing device 4 is relative with the moulding position in master mold 1, heater 5 is relative with film position.Grabbing device utilizes vacuum adsorption force absorption moulding, device for simultaneous heating 5 preheated films.Grabbing device adsorbs after moulding, and film preheating completes.Machinery arm 3 rises, and moulding is moved to assigned address.Mould matched moulds, continues next moulding and produces.Circulation, produces moulding in batch successively.
