Accompanying drawing 2 driving device structure sketch moving for driving, the cover half movable insert;
Accompanying drawing 3 is the die structure dwg moving among the embodiment 1, that the cover half movable insert is in second assigned address;
Accompanying drawing 4 is the position view of drive unit among Fig. 3.
The specific embodiment
Mould of the present invention is mainly used in household appliances, auto parts machinery, the production of bicolor plastic cement goods such as mechanical fitting and articles for daily use.As shown in Figure 1, the injection mold that is used for molding flat color matching product in the present embodiment is mainly used in the double-colored goods that have first color part and second color part on the length that is molded over product or the width, and it has comprised the basic structure of common plastic mould.As cover half 1, dynamic model 2 etc.Cover half 1 is corresponding with double color injection device (comprising first nozzle 31 and second nozzle 32), is provided with the first color part die cavity 4 that forms goods between dynamic model 2 and the cover half 1; Cavity section at dynamic model 2 is provided with dynamic model movable insert 21, the cavity section of cover half 1 is provided with and dynamic model movable insert 21 corresponding cover half movable inserts 11, forms at least the second color part die cavity 5 of goods between dynamic model movable insert 21 and cover half movable insert 11 opposing end faces; Dynamic model movable insert 21 is connected with drive unit respectively with cover half movable insert 11, in the effect lower edge die sinking direction reciprocating motion of drive unit.Saidly among the present invention be meant the direction parallel, both comprised, also comprise perpendicular to the motion of cover half towards the cover half direction perpendicular to the motion of dynamic model towards the dynamic model direction with the die sinking direction along the die sinking direction.
Wherein drive unit comprises hydraulic-driven, Mechanical Driven, manual drives, blast driving etc.Because the concrete structure of these drive units all belongs to those skilled in the art's common practise, therefore be not described in detail.Disclose a kind of fluid pressure drive device in accompanying drawing 2, it comprises that one is arranged on cover half movable insert 11 or dynamic model movable insert 21 bottoms and realizes by the wedge 6,7 that inclined-plane (gradients of about 3～10 degree) cooperate with it.Wedge 6,7 is connected with the piston rod of oil cylinder, does the reciprocating motion of level under the effect of oil pressure, thereby makes the reciprocating motion that cover half movable insert 11 or dynamic model movable insert 21 are done along the die sinking direction.As shown in Figure 2; the wedge 6 of cover half is in the position of withdrawal; the wedge 7 of dynamic model is in the position of stretching out; thereby cover half movable insert 11 or dynamic model movable insert 21 are all shifted to cover half 1 direction; the second color part die cavity 5 is in the position isolated with the first color part die cavity 4; i.e. first assigned address, first nozzle 31 of double color injection device is injection in dynamic model movable insert 21 and the cover half movable insert 11 formed second color part die cavitys 5.On the contrary; as shown in Figure 4; the wedge 6 of cover half is in the position of stretching out; the wedge 7 of dynamic model is in the position of withdrawal; thereby cover half movable insert 11 or dynamic model movable insert 21 are all shifted to dynamic model 2 directions; the second color part die cavity 5 is in the position that is connected with the first color part die cavity 4, i.e. second assigned address, and second nozzle 32 of double color injection device is injection in dynamic model 2 and the cover half 1 formed first color part die cavity 4.Wherein the control device of hydraulic jack is connected by RCA with the double color injection device, therefore can control moving and the injection action of cover half movable insert 11 or dynamic model movable insert 21 exactly.
In addition, for efficient and the accuracy of action that improves mould, dynamic model movable insert 21 moves back and forth under the drive unit effect synchronously with cover half movable insert 11.Dynamic model movable insert 21 is thick quite with the material of cover half movable insert 11 reciprocating strokes and goods second color part.At this moment; the forming surface of the whole lower surfaces of product all can be made on the dynamic model movable insert 21 (as shown in Figure 3); when at first nozzle 31 during to the second color part die cavity, 5 injections; as shown in Figure 1; dynamic model movable insert 21 can and the molded surface of cover half 1 between form a kind of relation of matched moulds, promptly this moment, dynamic model movable insert 21 part molded surface played the effect of envelope material.
The concrete injection step of this mould is as follows:
A): the dynamic model 2 and cover half 1 matched moulds of mold base, drive unit drives dynamic model movable insert 21 and moves to first assigned address with cover half movable insert 11 to cover half 1 direction, and first nozzle 31 of double color injection device is injection in dynamic model movable insert 21 and the cover half movable insert 11 formed second color part die cavitys 5;
B): pressurize and cooling certain hour;
C): drive unit drives dynamic model movable insert 21 and moves to second assigned address with cover half movable insert 11 to dynamic model 2 directions, and second nozzle 32 of double color injection device is injection in dynamic model 2 and the cover half 1 formed first color part die cavity 4;
D): pressurize and cooling certain hour, dynamic model 2 and cover half 1 die sinking.
Thereby obtain having the goods of first color part and two kinds of different colours of second color part and/or material, in die sinking process, realize the disposable plane colorant match.
Conversely, dynamic model movable insert 21 also can move to first assigned address to dynamic model 2 directions with cover half movable insert 11, and then moves back to second assigned address to cover half 1 direction.
In addition, also can be when cover half 1 direction move to first assigned address at dynamic model movable insert 21 and cover half movable insert 11, second nozzle 32 of double color injection device is injection in dynamic model 2 and the cover half 1 formed first color part die cavity 4; When dynamic model movable insert 21 and cover half movable insert 11 move to second assigned address to dynamic model 2 directions, first nozzle 31 of double color injection device is injection in dynamic model 2 and the cover half 1 formed second color part die cavity 5.
In addition, dynamic model movable insert 21 can be at first assigned address with cover half movable insert 11 residing initial positions, also can be at second assigned address (as above-mentioned embodiment).If initial position is in first assigned address, after die sinking finishes, increase a step e so): drive unit driving dynamic model movable insert 21 moves to first assigned address with cover half movable insert 11 along the die sinking direction and gets final product.Specifically select the sort of mode for use, can come according to specific circumstances to determine.
In the present invention; dynamic model movable insert 21 and cover half movable insert 11 are not limited to moving along the die sinking direction; it also can be the angle reciprocating motion that is a certain setting with the die sinking direction; its concrete angle is mainly determined according to the design feature of product; this simple conversion; therefore the common practise that belongs to those skilled in the art also falls into protection scope of the present invention.
