Abstract
A intramode injection and intramode vacuum detective device relates to the technology field of the device for effectively protecting mould during the production process of intramode injection mould, especially relates to the device which can automatically detect the state of hardware installation in mould. The detective device Intramode injection and intramode vacuum can resolve the problems of no-guarantee of safety in the process of hardware injection, easy damage of mould and low production efficiency. The device comprises an intake-tube used for connecting gas sources, a magnetic valve connected with the intake-tube, a vacuum generator connected with the magnetic valve, and a negative pressure sensor arranged at the negative pressure end of the vacuum generator through three-way pipe, and a mould sucker connecting pipe. The magnetic valve is also connected with electric signal of the injection machine, and opens when the injection machine thimble withdraws the signal. The negative pressure sensor is connected with the signal of the control circuit of mode locking of the injection machine, and provides mode locking signal for the injection machine. When the sucker within the mould neglects loading hardware, or the sucher is not installed in the right place, or the hardware drops in the process of die assembly, then the corresponding sucker will leak air, the negative pressure of the pipe will be reduced, the negative pressure sensor will be unable to provide mode locking signal for mode locking control circuit of the mould, the mould will not process die assembly, which can effectively protect the production safety of the mould and can improve the production efficiency.
Description
Technical field
The utility model relates to a kind of in-mould injection mould production process that is used for, and effectively protects the device technique field of mould, is specifically related to detect automatically the device of five metals installation situation in the mould.
Background technology
Along with development of times, increasing product develops towards small and exquisite direction, as mobile phone, cube little, and the intensity height will reach this effect, and in-mould injection five metals steel disc produces thereupon.Nowadays, big of most phone housings all use in-mould injection, but owing to need put into handware mold-closing injection more earlier during injection moulding, the safety of handware in injection moulding process seems very important.At present, when mainly relying on manually-operated, carefully put into, in the matched moulds, the careful observation prevents the pressing mold that drops in the five metals matched moulds process, and production efficiency is low, and is extremely dangerous, the operator in an unguarded moment, mould will damage, and does not possess production in enormous quantities.
Summary of the invention
In sum, of the present utility model is not have guarantee, easy mold damage, the technical problem that production efficiency is low, and vacuum checking device in a kind of in-mould injection mould that proposes in order to solve the safety of existing handware in injection moulding process.
For solving the technical problem that the utility model proposed, the technical scheme that adopts is: vacuum checking device in the in-mould injection mould, it is characterized in that: include the air inlet pipe that is used to connect source of the gas, the magnetic valve that is connected with air inlet pipe, the vacuum generator that is connected with magnetic valve, and the negative pressure pressure sensor that is connected vacuum generator negative pressure end by three-way pipe simultaneously is connected tracheae with the mould sucker; Described magnetic valve also is connected with the injection machine signal of telecommunication, and magnetic valve is opened when the injection machine thimble moves back signal; Described negative pressure pressure sensor is connected with the locked mode control circuit signal of telecommunication of injection machine, for the injection moulding machine mode-locking control circuit provides the locked mode signal.
Also be provided with oil water separator between described air inlet pipe and the magnetic valve.
Also include a casing, described oil water separator, magnetic valve, negative pressure pressure sensor and vacuum generator all are located in the casing.
The beneficial effects of the utility model are: can detect the in-mould injection handware automatically by the utility model situation is installed; neglected loading handware on the sucker in the mould; or be not in place; or handware comes off in the matched moulds process, and corresponding sucker begins gas leakage, and endotracheal negative pressure reduces; the negative pressure pressure sensor just can't provide the locked mode signal for the locked mode control circuit of mould; mould does not just have mould assembling action yet, effectively protects mould to keep the safety in production, and enhances productivity.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is a decomposing state structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and preferred specific embodiment structure of the present utility model is further described:
Shown in seeing figures.1.and.2, the utility model includes a casing 6, is located at oil water separator 2, magnetic valve 3, vacuum generator 4 and negative pressure pressure sensor 5 in the casing 6.Air inlet pipe 1 a wherein end is connected with air compressor machine, finally provide the work source of the gas for vacuum generator 4, the other end of air inlet pipe 1 connects the air inlet end of oil water separator 2, oil water separator 2 with the water-oil separating in the source of the gas after, pure air-flow is connected with the source of the gas input of vacuum generator 4 through magnetic valve 3, the negative pressure end of vacuum generator 4 is connected with a three-way pipe, and the two ends in addition of threeway are connected tracheae 7 with the negative pressure pressure sensor 5 of vacuum generator 4 negative pressure ends with the mould sucker respectively.
The mould sucker connects the other end of tracheae 7 draws outside the casing 6, and the sucker that adsorbs handware with being used in the mould is connected, and handware is loaded on the sucker, shutoff sucker pore.When having on the sucker in the mould when five metals is installed, under the effect of vacuum generator 4, the mould sucker connects in the tracheae 7, and just can form relative vacuum in the pipeline of three-way pipe and 5 of negative pressure pressure sensors, and negative pressure pressure sensor 5 is used to respond to negative pressure value.
Described magnetic valve 3 also is connected with the injection machine signal of telecommunication, when injection machine sends thimble and moves back signal, thereby Synchronization Control magnetic valve 3 open, after magnetic valve 3 was opened, vacuum generator 4 was started working thereupon, it is air-breathing that the mould sucker connects tracheae 7 beginnings; Described negative pressure pressure sensor 5 also is connected with the locked mode control circuit signal of telecommunication of injection machine, the mould sucker connect tracheae 7 air-breathing in, negative pressure pressure sensor 5 detects the interior vacuum of pipe that the mould sucker connects tracheae 7 simultaneously, when vacuum reaches preset value in the pipe, represent the handware installation in the mould to put in place, negative pressure pressure sensor 5 provides the locked mode signal for the injection moulding machine mode-locking control circuit.When mould in the locked mode process, when handware came off from sucker, the sucker place will leak gas, negative pressure pressure sensor 5 will be sensed the negative pressure value that the mould sucker connects in the tracheae 7 and reduce, lock stop modulo operation is immediately avoided the damage of mould.
