Abstract
The utility model relates to a hydraulic safety system of a hydraulic clamp. The hydraulic safety system comprises a movable mould clamping connector (1) and a fixed mould clamping connector (2), wherein the movable mould clamping connector (1) and the fixed mould clamping connector (2) are used for connecting a movable mould hydraulic clamp and a fixed mould hydraulic clamp; each of the movable mould clamping connector (1) and the fixed mould clamping connector (2) is provided with a pressure sensor. According to the hydraulic safety system of the hydraulic clamp, the pressure in the hydraulic clamp can be monitored in real time; if the clamp is used for clamping, an alarming signal is sent to prevent other movements from occurring only if the pressure in the clamp is detected to be not enough.
Description
Technical field
The utility model belongs to technical field of hydraulic, particularly relates to a kind of hydraulically operated fixture hydraulic safe system.
Background technology
Plastic injection-moulded industry and metal plate punching industry, mould is fixed on plastic molding press or high-precision punch press and originally all adopted clamping cap to fix mould by screw, this fixed form wastes time and energy, and is absolutely unsafe, and easily occurs the security incidents such as mould landing in operation process.Along with improving constantly of industrialization degree, frequently change at many industry requirement moulds, and mould replacing time is had to certain requirement, be affected and be unlikely whole production line, this just requires a kind of easy to operate, efficient, safe mould holding system to complete this task.Full automatic hydraulically operated fixture system substantially all belongs to standard configuration in American-European and Japanese injection moulding and punching press industry, but owing to being subject to technological development Bottleneck Restrictions, only has at present America and Europe and Japanese Ji Jia enterprise to grasp this technology.My company grasps this technology completely at present, batch production full automatic hydraulically operated fixture.Because relating to the person and property safety, adopt the occasion of hydraulically operated fixture all take safety as first object condition, system hydraulic principle will be considered all occurrent situations in the time of design.The current hydraulic principle in use is for to arrange a press detection sensor at major loop, as shown in figure mono-.At certain under special circumstances, if operating personnel are in the situation that having pressed the clamping of fixed form hydraulically operated fixture, fixed form fixture completes normal locking, but in the time pressing the clamping of moving die plate hydraulically operated fixture, occur that mould ampere-hour tilts, sense switch on hydraulically operated fixture cannot complete detection, clamps program and cause completing dynamic model.But now on hydraulic system major loop, pressure sensor there will not be alarm condition.If now operating personnel not by specification explanation go correct mould lifting, and go to operate injection moulding machine mould open action, side can cause mould landing situation, causes the accident.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hydraulically operated fixture hydraulic safe system, unreasonable to solve original hydraulic control system design, has the problem of potential safety hazard.
The utility model solves the technical scheme that its technical problem adopts: a kind of hydraulically operated fixture hydraulic safe system is provided, comprise that dynamic model clamps interface, cover half clamps interface, the first pressure sensor, the second pressure sensor, the first reversal valve, air-driven hydraulic pump and the second reversal valve, described dynamic model clamps interface and cover half clamping interface lays respectively on moving mold and fixed mold, dynamic model clamps interface one end and is connected with second reversal valve one end, dynamic model clamps on the pipeline between interface one end and the second reversal valve the second pressure sensor is installed, cover half clamps interface one end and is connected with first reversal valve one end, cover half clamps on the pipeline between interface one end and the first reversal valve the first pressure sensor is installed.
The other end of the second described reversal valve is communicated with air-driven hydraulic pump.
The other end of the first described reversal valve is communicated with air-driven hydraulic pump.
Beneficial effect
The utility model can be monitored the pressure of hydraulically operated fixture inside in real time, as carrying out fixture when folder, as long as fixture internal pressure deficiency detected, can send alarm signal and stops other action to be carried out.
Accompanying drawing explanation
Fig. 1 is former hydraulic control schematic diagram one.
Fig. 2 is the utility model hydraulic control schematic diagram two.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Fig. 1～Fig. 2, a kind of hydraulically operated fixture hydraulic safe system, comprise that dynamic model clamps interface 1, cover half clamps interface 2, the first pressure sensor 3, described dynamic model clamps interface 1 and cover half clamping interface 2 lays respectively on moving mold and fixed mold, and dynamic model clamps on interface 1 the first pressure sensor 3 is installed, and cover half clamps on interface 2 the first pressure sensor 3 is installed.In the time that air-driven hydraulic pump 6 is worked, atmospheric pressure is converted to hydraulic pressure, be connected to the first reversal valve 5 and the second reversal valve 7 by fluid pressure line.Then be connected respectively to dynamic model and clamp interface 1 and cover half clamping interface 2.The first pressure sensor 3 is arranged on cover half and clamps between interface 2 and the first reversal valve 5, and the second pressure sensor 4 is arranged on dynamic model and clamps between interface 1 and the second reversal valve 7, and it is relatively independent pipe-line system that dynamic model clamping interface 1 and cover half clamp interface 2.The first pressure sensor 3 can timely monitor cover half clamps the pressure of interface 2, and the second pressure sensor 4 can timely monitor dynamic model clamps the pressure of interface 1.Once pressure report to the police lower than setting value, guarantees oil piping system safety.And shown in Fig. 1, pressure sensor can only detect the pressure in working connection system, cannot carry out in good time pressure monitoring to dynamic model clamping interface 1 and cover half clamping interface 2.
Claims (3)
1. a hydraulically operated fixture hydraulic safe system, comprise that dynamic model clamps interface (1), cover half clamps interface (2), the first pressure sensor (3), the second pressure sensor (4), the first reversal valve (5), air-driven hydraulic pump (6) and the second reversal valve (7), it is characterized in that: described dynamic model clamps interface (1) and cover half clamping interface (2) lays respectively on moving mold and fixed mold, dynamic model clamps interface (1) one end and is connected with the second reversal valve (7) one end, dynamic model clamps on the pipeline between interface (1) one end and the second reversal valve (7) the second pressure sensor (4) is installed, cover half clamps interface (2) one end and is connected with the first reversal valve (5) one end, cover half clamps on the pipeline between interface (2) one end and the first reversal valve (5) the first pressure sensor (3) is installed.
2. a kind of hydraulically operated fixture hydraulic safe system according to claim 1, is characterized in that: the other end of described the second reversal valve (7) is communicated with air-driven hydraulic pump (6).
3. a kind of hydraulically operated fixture hydraulic safe system according to claim 1, is characterized in that: the other end of described the first reversal valve (5) is communicated with air-driven hydraulic pump (6).
