Abstract

The utility model relates to a device for heating the inner surface of a mould, which is characterized in that a forming machine and a control device are mutually connected, a mechanical arm which moves inside and outside the mould is attached with a heating device directly heating the inner surface of the mould, and an inductor and a cooling pipeline are also arranged on the mould. During mould injection, the heating device directly heats the inner surface of the mould when the mechanical arm extends into a forming mould cavity in the mould; according to the upper normal temperature value and the lower normal temperature value set by the control device in advance, when the inductor detects that the mould temperature reaches the upper standard temperature value, the heating device is required to stop heating and sends information to drive the forming machine to close and inject the mould. After injection, the cooling pipeline begins to cool in real time. The mould is opened and the product is obtained when the temperature drops to the preset lower normal temperature value.

Description

The device that is used for the heating mould inner surface

Ji Intraoperative field

The utility model relates to the device of inner surface in a kind of heating mould, this device can be after formed product cooling die rapidly, obtaining portion's product, and the problem of minimizing demoulding after-contraction than apperance.

Bei Jing Ji Intraoperative

Make in the De Ji Intraoperative field in plastic shaping,, carried out various trials and improved the mould molding temperature for obtaining the appearance of better quality.

For example in molding manufacture procedure, usually by directly heightening Mo Wen or expecting that temperature reaches above-mentioned high-quality apperance effect, but in this operation process, Chang Yi causes cool time long, the intensity and the hot property of injection-molded product have been reduced, thereby make the possibility increase of demoulding after-contraction cause distortion easily, and reduced the output of molding process.

The utility model content

Therefore, the utility model is at the problems referred to above that occur among the Xian You Ji Intraoperative, the device of inner surface in a kind of direct heating mould is provided, this device make with mold heated behind predetermined temperature, can fill mould and can injection molding die be cooled off rapidly with the molten plastic that is used for injection molding in case finish injection molding, thereby improved the presentation quality of product, improved the intensity and the hot property of injection-molded product.

For achieving the above object, the utility model provides the device of inner surface in a kind of direct heating mould, it comprises: a make-up machine, this make-up machine comprises that one is used for the mould of injection mo(u)lding, one is pasted with a heater and movable mechanical arm inside and outside mould, and this heater is used for inner surface in the direct heating mould, and an inductor and a cooling line that is used to detect mold temperature is located at mould; Another control device is connected with mould and mechanical arm by circuit, and this control device comprises by the interconnective heating control apparatus of circuit, cooling control device, mechanical arm control device and moulding control device.

Before the injection molding, heating control apparatus and cooling control device all require to set respectively normal temperature value about in the of according to the injection molding plastic, then, earlier heater is stretched into the die for molding die cavity by means of mechanical arm, directly to inner surface heating in the mould, detect temperature up to inductor and reach the standard temperature value, then passing an information to heating control apparatus back heats to stop heater, mechanical arm also shifts out shaping mold cavity at this moment, make-up machine begins the matched moulds injection then, make cooling line begin to breath to the control device of lowering the temperature of then delivering a letter after injection finishes to the mould cooling, but when treating that mold temperature reaches to standard temperature value down then die sinking get product.

So, mould is after being rapidly heated, can lower the temperature rapidly by cooling line again, thereby improved the presentation quality of product, the physics and the chemical characteristic that keep plastics in the product, improved the intensity and the hot property of product, improved the output in the manufacture process and reduced production cost of products.

The specific embodiment

Fig. 1 is a schematic diagram, is depicted as according to the utility model, utilizes the device of inner surface in a kind of heater 120 direct heating moulds 130.

This device is established a make-up machine 100 and is connected with a control device 200, wherein make-up machine 100 comprises a mould 130 and a mechanical arm 110, and but this mould 130 is by in the folding, bed die is formed, and be provided with a molding chamber 1303 in this mould 130, on mould 130, then be provided with cooling line 1302, and this mould 130 is provided with inductor 1301, moreover, attach a heater 120 on this mechanical arm 110, be used for directly mould 130 inner surfaces being given contact or contactless heating, this heater 120 is to shift out or move in the mould 130 by a mechanical arm 110.

In addition, this control device 200 is provided with a heating control apparatus 210, this heating control apparatus 210 is connected with heater 120 and inductor 1301 by circuit 300, make heating control apparatus 210 can pass through the temperature-sensitive effect of inductor 1301, and the heat effect of heater 120, the heating-up temperature of mould 130 is controlled; And another cooling control device 220 that this control device 200 is comprised also is connected with cooling line 1302 and inductor 1301 by circuit 300, and this cooling line 1302 reduces the interior temperature of mould 130 by Fluid Volume and flowing time; Moreover, be respectively equipped with the mechanical arm control device 240 and the moulding control device 230 of control mechanical arm 110 and mould 130 foldings in this control device 200, and interconnect with heating control apparatus 210 and cooling control device 220 respectively.

When product is taken out in mould 130 die sinkings, when control device 200 can be passed to a signal mechanical arm control device 240 and cooling control device 220, cooling control device 220 is after receiving signal, stop cooling line 1302 work rapidly to avoid continuing to act on mould 130 temperature, simultaneously mechanical arm control device 240 is received and is promptly controlled mechanical arm 110 behind the signal and begin action, take out product and pass a signal and give heating control apparatus 210, and this heating control apparatus 210 and cooling control device 220 are before operation, set normal temperature value about in the of respectively according to the injection molding plastic, after heater 120 is received order, stretch into by mechanical arm 110 immediately that inner surface heats in 1303 pairs of moulds 130 of shaping mold cavity, detect mould 130 temperature when reaching the standard temperature value up to inductor 1301, promptly transmit a signal to heating control apparatus 210, control heater 120 stops mould 130 heating and passes a signal to mechanical arm control device 240, makes its mechanical arm 110 shift out mould 130.

Then, make-up machine 100 beginning matched moulds injections treat that injection finishes aftershaping machine 100 passbacks one signal to the control device 220 of lowering the temperature, and rapidly mould 130 are lowered the temperature until following standard temperature value after cooling line 1302 receives orders, and get final product die sinking.
