Technical field
The utility model relates to a kind of injection machine, particularly relates to a kind of injection machine with the hot mechanism of the shallow indicated airspeed of injection mold die cavity.
Background technology
Injection moulding all is widely used in industrial every field as one of forming method important in the plastic processing.The product of and high request particularly little along with the appearance of 3C and high-tech product is more and more, show the appearance of product as various optics, people are more and more higher to the requirement of precision, surface quality and the intensity of plastic product, and injection molding technology has run into unprecedented challenge.For some defectives in the injection moulding process, as: weld mark, current mark, injecting products presentation quality difference etc., common injection molded technology can't solve at all, and wherein critical technical problems is the variation of quick dynamic analog temperature and controls and can't reach.If mold temperature remains on more than the material inversion point and then can descend and not influence too many molding cycle fast again in the stowing operation, then problem such as weld mark, current mark just can be readily solved.
The equipment that is adopted above the existing market is fixing heating entire die, entire die heats up and slowly can't lower the temperature rapidly again like this, can exert an influence the service life to entire die, heats entire die simultaneously and produce a lot of unnecessary energy wastes, strengthened the production cost of enterprise.In addition in actual production process, the injecting products that the heating entire die produces is owing to exist appearance qualities such as weld mark, current mark, in order to cover up the blemish of above-mentioned injecting products, must carry out secondary operations to the spraying of injecting products surface, adopt surperficial spraying technology, not only waste raw materials for production, waste energy, increase the production cost of injecting products, and cause serious environmental to pollute, harm operating personnel's health of human body.
The utility model content
Fixing heating entire die when solving in the prior art injection moulding, thereby influence the service life of mould, there is the problem of presentation qualities such as weld mark, current mark in the injecting products of Zhi Zaoing simultaneously, the utility model provides a kind of the mould cavity surface heated it is rapidly heated and cools off rapidly, thereby reaches the injection machine of better injection moulding effect.
In order to achieve the above object, technical solution adopted in the utility model is:
A kind of injection machine with the hot mechanism of the shallow indicated airspeed of injection mold die cavity, comprise base, injection machine solid plate and Injection Motor Template, on base, be provided with Injection Motor Template and injection machine solid plate, be provided with master mold in injection machine solid plate inboard, be provided with male model in the Injection Motor Template inboard, it is characterized in that: injection machine is provided with high-frequency heating apparatus, described high-frequency heating apparatus is connected with heater by connecting line, described heater can extend in the master mold die cavity, and the master mold cavity surface is heated to the part from 0.2 millimeter on surface.
Aforesaid a kind of injection machine with the hot mechanism of the shallow indicated airspeed of injection mold die cavity, it is characterized in that: also comprise mechanical arm, top at the injection machine solid plate is provided with mechanical arm, described mechanical arm comprises the translation arms at top and is connected the lifting arm of translation arms one end, is connected with heater in the bottom of lifting arm.
The beneficial effects of the utility model are: injection machine of the present utility model is by the heater mould cavity surface temperature that can raise fast, the temperature height, good fluidity, and only the mould cavity surface is heated, heating part is less, so cooling velocity is very fast, can reach the effect of rapid heat cycle, the formed product quality is good.When moulding, also can eliminate weld mark and current mark that injecting products produces, improve bond strength, eliminate residual stress, improve the lustrous surface of material, improve the product appearance quality, strengthen molding effect.Need not simultaneously entire die is heated, prolonged the service life of mould, also reduced the energy that the entire die heating is consumed, reduced cost.Injecting products also need not to carry out the secondary operations operation in addition, and properties of product are better, and cost is also lower.

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of injection machine with the hot mechanism of the shallow indicated airspeed of injection mold die cavity, comprise base 1, Injection Motor Template 2 and injection machine solid plate 3, on base 1, be provided with Injection Motor Template 2 and injection machine solid plate 3, be provided with male model 4 in Injection Motor Template 2 inboards, be provided with master mold 5 in injection machine solid plate 3 inboards, injection machine is provided with high-frequency heating apparatus 6, high-frequency heating apparatus 6 is connected with heater 9 by connecting line 7, be provided with oil cylinder 8 in base 1, the bottom of heater 9 is connected with the cylinder rod of oil cylinder 8.
As shown in Figure 1, before the injecting products, male model 4 and master mold 5 are separated, heater 9 is placed between male model 4 and the master mold 5, utilize oil cylinder 8 to drive cylinder rods and move to the inside, heater 9 is understood the slowly cavity surface of close master mold 5 like this, after the cavity surface of arrival master mold 5, high-frequency heating apparatus 6 is started working, and utilizes 9 pairs of master mold 5 cavity surface of heater to be rapidly heated to the part from 0.2 millimeter on surface and reaches about 300 degree.When temperature is close to or higher than 300 when spending, close high-frequency heating apparatus 6, heater 9 no longer carries out heating work.Simultaneously as shown in Figures 2 and 3, oil cylinder 8 moves to the origin-location with heater 9, and utilizes cylinder rod drive heater 9 to turn clockwise 90 °, makes heater 9 become the parallel position state with injection machine base 1 table top.At this moment Injection Motor Template 2 drive male models 4 move to master mold 5, and final matched moulds.Required injection moldable polymers is expelled in the mould cavity, then in injection moulding and pressure maintaining period, because just the cavity surface of master mold 5 is heated, so the die cavity of master mold 5 can cool off fast, when mold temperature is cooled to a certain degree, open mould like this, take out product.Can allow mould rapid heat cycle in injection moulding process by the said equipment, when formed product, can eliminate the weld mark and the current mark of generation like this.
