Background technology
The plastic molding press of commonly using sees also first and second figure, comprises a mould unit 1 and facility 2 that shoot material.
The formation substantially of this mould unit 1 generally comprises a fixed mould 10 and a flexible mould 15.Fixed mould 10 is fixed in the top of a hollow support 11, and periphery is established four strut members 19, and this flexible mould 15 is established on the common top of this body of rod 19, and the bottom is a substrate 151 then.Establish an oil cylinder 16 and two toggles 17,18 between this fixed mould 10 and the substrate 151; the cylinder rod of oil cylinder 16 is flexible, controls 17, the 18 right and wrong actions of two toggles, promotes this substrate 151; with these flexible mould 15 liftings of four poles 19 pulling, in order to do with fixed mould 10 matched moulds or divide mould.
The formation substantially of these facility 2 that shoot material generally comprises and penetrates cylinder 21, can hold the plastics of semi-molten state, and one shoots material 22 is incorporated into this and penetrates cylinder 21 ends; It moves back and forth by a dynamical system 23 control to penetrate cylinder 21, advance to move make shoot material 22 with the die orifice wedging of mould unit 1, shoot material and inject in the middle of the die cavity, in order to do moulding one plastic product through the ejaculation runner of mould; Retire that then making shoots material 12 separates with die orifice.
The shortcoming of above-mentioned facility is listd and is described as follows:
A, please cooperate Fig. 3,4, be directly connected in fixed mould 10 bottoms (A as shown in FIG., B, C position) by the cylinder rod 161 and the toggle 17,18 of apparent oil cylinder 16 among the figure.Mould high temperature conducts to oil cylinder 16 by fixed mould 10 and cylinder rod 161 easily.According to actual thermometric, mould 10 is 175 degree Celsius, transfers to die holder and makes about 65 degree of its temperature, and die holder transfers to the heat temperature that oil cylinder 16 and two toggles 17,18 make 40 degree Celsius of its generation by the binding site of A, B, C with hot temperature respectively.Make oil cylinder 16 be in improper heat temperature as the time spent, expanding with heat and contract with cold makes oil cylinder 16 end close elasticity seal ring breakage, reduction of service life easily.
B, also as Fig. 3,4, oil cylinder 16 and toggle 17,18 are not to act directly on flexible mould 15, but the substrate 151 that acts on the below flexible mould 15 of pulling top indirectly again.Oil cylinder 16 is the weight of bearing substrate 151, four strut members 19, two suite elbows 17,18 and flexible mould 15 in fact, overload, reduction of service life.
C, for cooperating the facility 2 that shoot material, the height of the aspect ratio general operation personnel convenient operation of fixed mould 10 be high, operating position is more inappropriate, is difficult to visualization and operates situation.
D, cooperate the facility 2 that shoot material, plastic molding press takies huge space, and the facility 2 that shoot material cooperate usually by several mould units 1 and arrange the flowline L that form, and as Fig. 5, the space selects for use restriction more.
E, as Fig. 5, one facility that shoot material cooperate to be arranged by several mould units 1 and form and by the flowline L of central control system control, the facility 2 that shoot material are arranged injection molding one by one according to the work flowline, make each mould unit 1 finish predetermined output, and will penetrate the plastic raw materials single sonorous stone in the cylinder 21.This flow process must not be interrupted arbitrarily before raw material is with single sonorous stone, otherwise the raw material that Yu is stayed in the cylinder promptly can't re-use, and caused wastage of material and clear cylinder trouble and cost burden.For fear of this problem, the plastic product on the same flowline except size can because of mould different discrepant, other all need identical as material, shape, color etc.And shoot material that facility 2 amounts of getting the raw materials ready are big, homochromy, homotype, must reach a certain higher quantity with the plastic product of material by single amount, can't manufacture in a small amount finished product or carry out the mobility adjustment according to the needs of order side.
F, the mould unit 10 on flowline be by central control system control, start and shutdown is all sought unity of action, so some mould unit of having finished predetermined output still is in holding state, causes energy waste.
The plastics of G, the facility 2 that shoot material enter die cavity via penetrating runner 100, and as Fig. 6, the plastics that penetrate in the runner are not the some of finished product, so be waste material, this waste material again because of with the releasing agent effect of penetrating water passage surface, therefore can't recycling, it is useless to form the raw material wave again.And also headroom fully of the plastics in the facility 2 of shooting material, this part also causes significant loss.According to statistics, waste material accounts for 22% of raw material total amount, and in other words, 78% the raw material of only having an appointment is used effectively, and utilization rate has to be hoisted.
Because above-mentioned multinomial shortcoming, the inventor thinks that plastic molding press still has quite big improvement space, so leadoff is studied.
