Abstract
The utility model relates to an aeration control device of an injection molding machine, which comprises a box. A box cover is connected with the box via hinges, a box lock is disposed on the box cover, a fixing plate is connected to the bottom surface of the inside of the box by bolts, a delay device and a counting device are disposed on the fixing plate and connected with an aeration switch on the outer portion of the right side of the box by leads, an aeration pipe is connected to the lower end of the aeration switch, and a power switch is disposed on the outer portion of the left side of the box and connected with the delay device and the counting device via leads. The aeration control device of the injection molding machine has the advantages that the aeration control device is low in cost and small in volume and occupied area, can be mounted in the injection molding machine, and can utilize air to replace nitrogen.
Description
Technical field
The utility model relates to a kind of injection machine ventilating control device.
Background technology
Injection mo(u)lding is to rely on injection machine that hot melt material is produced pressure to enter die cavity, and huge pressure not only makes material be full of die cavity, and makes it to be close to die surface, thereby it is complete to obtain profile, the workpiece of surperficial high-quality.Gas-assisted injection molding process is to follow material to inject the gas of certain pressure, and gases at high pressure have the characteristic of advancing along the minimum direction of resistance, and gas channel always passes through in the material hotter, that viscosity is lower in die cavity, and the material of being close to die wall solidifies earlier.Therefore, gas is close to the die wall surface at the middle material that promotes of melt basically.In injection moulding process, form air flue or claim cavity simultaneously in the inside of workpiece.Gas generally adopts inert gas, mainly is nitrogen.The nitrogen that uses in the production need prepare or buy, and has increased production cost.
The utility model content
It is low that the purpose of this utility model provides a kind of cost, and the injection machine ventilating control device that volume is little can be loaded in the injection machine, and floor space is little, and can use air to replace nitrogen, reduces enterprise's production cost.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of injection machine ventilating control device comprises casing, and described casing is connected with Box Cover by hinge, and Box Cover is provided with the casing lock; Underrun bolt in the casing is connected with fixed head, and fixed head is provided with time-delay mechanism and time set, and time-delay mechanism and time set are by the gas-filled switching tube of lead connect box right hand external, and the gas-filled switching tube lower end is connected with gas tube; The casing left hand external is provided with power switch, and power switch connects time-delay mechanism and time set by lead.
The beneficial effects of the utility model are: low cost of manufacture, and volume is little, can be loaded in the injection machine, and floor space is little, thereby saves the space, and can use air to replace nitrogen, reduces the production cost of enterprise.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described a kind of injection machine ventilating control device of the utility model embodiment;
Fig. 2 is the right view of the described a kind of injection machine ventilating control device of the utility model embodiment;
Fig. 3 is the left view of the described a kind of injection machine ventilating control device of the utility model embodiment.
Among the figure:
1, casing; 2, hinge; 3, Box Cover; 4, casing lock; 5, bolt; 6, fixed head; 7, time-delay mechanism; 8, time set; 9, gas-filled switching tube; 10, gas tube; 11, power switch.
The specific embodiment
As Figure 1-3, the described a kind of injection machine ventilating control device of the utility model embodiment comprises casing 1, and described casing 1 is connected with Box Cover 3 by hinge 2, and Box Cover 3 is provided with casing lock 4; Underrun bolt 5 in the casing 1 is connected with fixed head 6, and fixed head 6 is provided with time-delay mechanism 7 and time set 8, and time-delay mechanism 7 and time set 8 are by the gas-filled switching tube 9 of lead connect box 1 right hand external, and gas-filled switching tube 9 lower ends are connected with gas tube 10; Casing 1 left hand external is provided with power switch 11, and power switch 11 connects time-delay mechanism 7 and time set 8 by lead.
Wherein, gas tube 10 1 ends are connected to high pressure airline, and gas tube 10 other ends are connected to injection mold inflation interface.
During use, at first turn on the power switch 11, after injection moulding finishes, sensor sends to this injection machine ventilating control device with signal opens time-delay mechanism 7, and gas-filled switching tube 9 is opened after the time that time-delay is extremely set, and time set 8 picks up counting simultaneously, air in the gas tube 10 enters injection mold and inflates, after timing finished, gas-filled switching tube 9 was closed, and inflation finishes.
