Abstract
A plastic mold's water channel sealed pressure-proof detection mechanism is characterized in that it comprises an electric pump; a water inlet of a bottom valve is arranged at the bottom of the electric pump; a water outlet of the electric pump is connected with a flow pipe which is connected with a manifold to reach a pressure testing pipe; the pressure testing pipe communicates with a water channel of a detected mold; the flow pipe is provided with a one-way flow valve and a pressure gauge; a pressure regulating valve is arranged in front of the one-way flow valve; a pressure release valve is mounted at the back of the one-way flow valve; the pressure release valve is connected with a decompression pipe to return a water tank; a backwater channel of the mold passes through a pressure release pipe to return the manifold which is connected with a backwater pipe to flow back to the water tank.
Description
Technical field
The utility model relates to the mould of plastics overall checkout equipment, particularly relates to mould of plastics aquaporin sealing resistance test mechanism.
Background technology
Along with the widespread use of plastic products in industries such as daily life, commercial unit and engineering constructions, the mould development of processing plastic goods becomes a large mainstay industry.Mould of plastics is in manufacture process, can exist the tolerance clearance problem of core and die cavity, exist mutual friction, mutual motion artifacts and unbalanced factor between each workpiece, and the problems such as cold and hot not even production efficiency is low in using, to the variety of issue that exists all will be by mould debugging and revise after just can obtain the matched moulds mould.Prior art has two kinds of methods to debugging and the correction of mould, a kind of is that the mould that will manufacture experimently is installed in the injection machine, outpour sample, judge according to the quality of sample whether mould is qualified, if sample is defective in one aspect, do not reach designing requirement, just mould is disassembled from injection machine, revise, also have problem after once revising, by unloading the mould tool dress mould that repairs a die, the method exists the length that expends time in again, need special-purpose injection machine die trial, manpower financial capacity's waste is very large.Another kind method is the individual event instrument test, for example surveys the gap, surveys seepage, and by testing rear correction mould, it is incomplete that the method exists test event, and operation is many, and some problem still will be revised by the practical sample of injection moulding, and work consuming is also large.
Summary of the invention
The purpose of this utility model is the shortcoming that exists in order to overcome prior art, provides a kind of simple in structure, easy to detect, to the aquaporin sealing resistance test mechanism of mould of plastics.
The technical scheme of the utility model mould of plastics aquaporin sealing resistance test mechanism is, it is characterized in that comprising electrodynamic pump, the water inlet that bottom valve is arranged under the electrodynamic pump, the water delivering orifice of electrodynamic pump connects flow pipe, flow pipe connects total water trap and arrives the pressure testing pipe, the pressure testing pipe is communicated with the aquaporin of tested mould, on the flow pipe road unidirectional induction valve and tensimeter are set, before unidirectional induction valve, pressure regulator valve is set, behind unidirectional induction valve, blowdown valve is set, blowdown valve connects relief pipe and gets back to water tank, and the backwater channel of the mould relief tube of flowing through is got back to total water trap, and total water trap connects the return pipe reflow tank.
The utility model discloses a kind of mould of plastics aquaporin and seal resistance test mechanism, electrodynamic pump is by motor-driven, when electrodynamic pump is opened, bottom valve is opened, water sucks from water inlet, send press water and export through flow pipe by the water delivering orifice of electrodynamic pump, the unidirectional induction valve of road in the valve group midway, the pressure testing mouth through total water trap flows to mould (detected object) to the pressure testing pipe again, and the aquaporin of mould is carried out pressure testing, electrodynamic pump quits work after arriving the force value of setting, observe tensimeter this moment, if force value remains unchanged, illustrates that then the sealing of mould aquaporin is passable, if force value is obvious decline, the aquaporin poor sealing is described then.In the pressure testing process, close blowdown valve, adjust pressure regulator valve, mix up force value, and close the automatic control of aquaporin recovery tank water level.This pressure testing mechanism by observing manometric force value, judges the leakage situation of aquaporin mainly for detection of sealing and the resistance to pressure of mould aquaporin.After pressure testing finishes, decontrol blowdown valve, discharge the mould aquaporin, the water recovery tank.The technical program is simple in structure, and is easy to operate, and detecting reliability is high.Relevant operation can be in conjunction with programming Control in the product of reality, and logical operation can obtain better effect.
Description of drawings
Fig. 1 is the utility model mould of plastics aquaporin sealing resistance test mechanism structural representation.
Embodiment
The utility model relates to a kind of mould of plastics aquaporin and seals resistance test mechanism, as shown in Figure 1, comprise electrodynamic pump 24, the water inlet that bottom valve 25 is arranged under the electrodynamic pump, the water delivering orifice of electrodynamic pump connects flow pipe 26, flow pipe 26 connects total water trap 32 and arrives pressure testing pipe 29, the pressure testing pipe is communicated with the aquaporin of tested mould 33, unidirectional induction valve 20 and tensimeter 21 are set on the flow pipe road, pressure regulator valve 23 is set before unidirectional induction valve, blowdown valve 22 is set behind unidirectional induction valve, blowdown valve 22 connects relief pipe 31 and gets back to water tank 27, the backwater channel of the mould relief tube 30 of flowing through is got back to total water trap 32, and total water trap connects return pipe 28 reflow tanks 27.Electrodynamic pump is by motor-driven, when electrodynamic pump 24 is opened, bottom valve 25 is opened, water sucks from water inlet, send press water and through flow pipe 26 output by the water delivering orifice of electrodynamic pump, the unidirectional induction valve 20 of road in the valve group midway, pressure testing mouth through total water trap 32 flows to mould (detected object) to pressure testing pipe 29 again, aquaporin to mould carries out pressure testing, and electrodynamic pump quits work after the force value that arrival is set, and observes tensimeter 21 this moment, if force value remains unchanged, the sealing that the mould aquaporin then is described is passable, if force value is obvious decline, the aquaporin poor sealing is described then.In the pressure testing process, close blowdown valve 22, adjust pressure regulator valve 23, mix up force value, and close the automatic control of aquaporin recovery tank water level.This pressure testing mechanism by observing the force value of tensimeter 21, judges the leakage situation of aquaporin mainly for detection of sealing and the resistance to pressure of mould aquaporin.After pressure testing finishes, decontrol blowdown valve 22, discharge the mould aquaporin, water recovery tank 27.The technical program is simple in structure, and is easy to operate, and detecting reliability is high.Relevant operation can be in conjunction with programming Control in the product of reality, and logical operation can obtain better effect.
