Abstract
The utility model discloses an injection mold locking oil channel of a two-plate type injection molding machine. The injection mold locking oil channel comprises an injection oil channel and a mold locking oil channel, wherein a mold locking boost motor is additionally arranged, and is used for supplying power for the mold locking oil channel; and a group of cartridge valves with pilot valves is additionally arranged between the injection oil channel and the mold locking oil channel, and is used for blocking a hydraulic oil channel for injection and mold locking. With the injection mold locking oil channel, the low-pressure injection can be realized, a production optimization effect is achieved, a mold is protected to a large extent, and the service life of the mold is prolonged.
Description
Technical field
The utility model relates to a kind of injection locked mode oil circuit of injection machine.
Background technology
The locked mode of existing two-plate injection machine is the Position Control mode, even if be that matched moulds is finished to the assigned address locked mode, see Fig. 1, during locked mode, P1, P2, P3 provides system dynamic, two position four-way valve V68(D35) electric, to the T oil return, pressure oil passes through inserted valve V66 and enters locked mode chamber (rod chamber) guide oil of inserted valve V66 through the A of V68.Two position four-way valve V63(D34) electric, to the T oil return, rodless cavity fluid is through the V64 oil sump tank through the B of V63 for the guide oil of inserted valve V64.
When locked mode finished the back injection, still by P1, P2, P3 provided system dynamic, two position four-way valve V11(D9) electric, pressure oil enters injecting cavity (rod chamber) through inserted valve V34.Three-position four-way valve V12(D32) electric, rodless cavity fluid is through inserted valve V36 oil sump tank, so it can't carry out stage control to clamp force, also just can't realize the low head injection function.
Summary of the invention
Technical problem to be solved in the utility model is the injection locked mode oil circuit that two-plate injection machine is provided for the above-mentioned deficiency that overcomes prior art, can rise on year-on-year basis with injection by locked mode, realizes low head injection.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the injection locked mode oil circuit of two-plate injection machine, comprise injection, locked mode oil circuit, it is characterized in that: increase the locked mode motor that boosts, power is provided for the locked mode oil circuit, also increase the inserted valve of one group of band pilot valve, be arranged between injection oil circuit and the locked mode oil circuit, cut off the hydraulic circuit of injection and locked mode.
Compared with prior art, advantage of the present utility model is: because less in the injection load of injection initial period, required clamp force is also less; Load increases when proceeding to the injection pressurize; clamp force also rises to maximum tonnage synchronously, realizes that injection and locked mode rise on year-on-year basis, just can realize low head injection by the utility model; reach the production optimization and protected mould to a great extent, prolong its service life.
Description of drawings
Fig. 1 is existing two plate machines injection locked mode asphalt principle figure.
Fig. 2 is the two plate machines injection locked mode asphalt principle figure of the utility model embodiment.
The specific embodiment
Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment.
As shown in Figure 2, the injection locked mode oil circuit of two-plate injection machine is to increase by a motor M 4 in existing injection locked mode oil circuit, and the locked mode when being used for injecting boosts.
Newly-increased inserted valve V43 and pilot valve V44 thereof are arranged between injection oil circuit and the locked mode oil circuit, and its function is for cutting off the hydraulic circuit of injecting with locked mode.
During locked mode, provide system dynamic by P4, among Fig. 2 the P4 pressure oil output through the E-E place, two position four-way valve V68(D35) electric, to the T oil return, pressure oil passes through inserted valve V66 and enters locked mode chamber (rod chamber) guide oil of inserted valve V66 through the A of V68.Two position four-way valve V63(D34) electric, to the T oil return, rodless cavity fluid is through the V64 oil sump tank through the B of V63 for the guide oil of inserted valve V64.
Action of injection provides system dynamic by P1, P2, P3, two position four-way valve V11(D9 simultaneously) must be electric, pressure oil enters injecting cavity (rod chamber) through inserted valve V34.Three-position four-way valve V12(D32) must be electric, rodless cavity fluid is through inserted valve V36 oil sump tank.
The power of above-mentioned motor M 4 can be 30KW to 55KW, and it changes according to the mode locking unit size.
Claims (1)
1. the injection locked mode oil circuit of two-plate injection machine, comprise injection, locked mode oil circuit, it is characterized in that: increase the locked mode motor that boosts, power is provided for the locked mode oil circuit, also increase the inserted valve of one group of band pilot valve, be arranged between injection oil circuit and the locked mode oil circuit, cut off the hydraulic circuit of injection and locked mode.
