The push disc 45, the U-shaped plate C44, the rotating rod 46, the threaded section 56, the threaded ring 47 and the rotating disc 48 are designed to adjust the air pressure alarm threshold, and the specific air pressure alarm threshold is adjusted as follows: the rotating rod 46 is driven by rotating the turntable 48, under the matching action of the threads of the threaded ring 47 and the threaded section 56, the rotating rod 46 drives the push disc 45 to enable the U-shaped plate C44 to move towards the direction close to the cylinder body 9, so that the telescopic rod 40 is compressed, the compression amount of the B spring 38 is increased, the value of the air pressure thrust blocked by the conical plug 39 is increased, and the air pressure alarm threshold value is increased; on the contrary, when the air pressure alarm threshold value needs to be reduced, the rotating disc 48 is rotated reversely, so that the U-shaped plate C44 moves towards the direction away from the cylinder body 9, the compressed amount of the telescopic rod 40 is reduced, the compressed amount of the B spring 38 is reduced, the value of the air pressure thrust blocked by the conical plug 39 is reduced, and the air pressure alarm threshold value is reduced. The purpose of adjusting the air pressure alarm threshold is as follows: during normal operation of the present invention, the maximum value of the pneumatic thrust exerted on the a piston 18 is limited by the pneumatic alarm threshold, and the maximum value of the pneumatic thrust exerted on the a piston 18 directly determines the weight of the ejected molded workpiece, i.e., the heavier the workpiece, the greater the pneumatic thrust required by the a piston 18, and conversely, the lighter the workpiece, the smaller the pneumatic thrust required by the a piston 18. In a word, the operator can adjust the air pressure alarm threshold according to the weight of different formed workpieces.
In the invention, the thread section 56 on the rotating rod 46 and the thread of the thread ring 47 adopt self-locking threads, so that the piston B43 is not moved when the rotating rod 46 is not adjusted. The air charging device and the control module for controlling the air charging device are all in the prior art. The inflating frequency of the inflating device is consistent with the working frequency of the die.
The horn 35 of the present invention may be a pneumatic alarm horn 35 available in the market.
The working process of the invention is as follows: under the state that the initial cylinder 9 is not inflated, the push plate 1 is positioned on the support plate 5, the lower surface of the push table 6 is tightly attached to the surface of the U-shaped plate A8 opposite to the push plate 1, and the transverse plate 12 is tightly attached to the clamping plate 21; the position of the piston A18 in the cylinder 9 is at the lowest state and is still higher than the heights of the hole A28, the hole B29 and the air inlet pipe 10; the A spring 25 in the A shell 27 is in a pre-stretched state, the lower end of the L-shaped plate A20 is clamped on the vertical surface of the A slide block 26 close to the inclined surface, and the air hole B33 and the A hole 28 are blocked by the A slide block 26. The conical plug 39 in the B shell 32 is sealed and embedded in the conical hole 60, the B spring 38 in the telescopic rod 40 is in a pre-compression state, and the A clamping block 50 is located at the position closest to the cylinder body 9. The C spring 51 in the C shell 53 is in a natural state, the C piston 52 is not positioned at the top end of the C shell 53 close to the B shell 32, and the position of the B fixture block 49 does not cause any contact to the reciprocating movement of the A fixture block 50 along the axial direction of the telescopic rod 40.
In a normal working state, after the die is closed, the closed die is just positioned on the push plate 1; after injection molding of the workpiece after die assembly is completed, the die is separated, and the workpiece is just positioned on the push plate 1 after separation; at this time, the control module controls the inflation device to inflate, and gas enters the cylinder 9 from the air inlet pipe 10. Along with the increasing of gas entering the cylinder 9, the gas pressure in the cylinder 9 is increased, and the piston 18A rises stably after the gas pressure thrust generated in the cylinder 9 breaks through the obstruction of the piston 18A; meanwhile, gas enters the C shell 53 from the square tube 55, so that the air pressure in the C shell 53 rises, the gas pushes the B clamping block 49 on the C piston 52 to move towards the telescopic rod 40 under the action of the pressure until the C piston 52 is clamped at the top end of the C shell 53, the inclined surface of the B clamping block 49 corresponds to the A clamping block 50, the A clamping block 50 is located between the B clamping block 49 and the conical plug 39, and the C spring 51 is stretched. During the rising process of the piston 18A, the thrust of the air pressure in the cylinder 9 to the conical plug 39 is smaller than the thrust of the B spring 38 to the conical plug 39.
The piston 18A pushes the push table 6 to move upwards through the ejector rod 13 until the push table is jointed with the push plate 1, and the transverse plate 12 is separated from the clamping plate 21; along with the increase of the air pressure in the cylinder 9, the upward thrust of the mandril 13 overcomes the gravity of the push plate 1 and the workpiece on the push plate 1 to continue moving vertically upwards, and the thrust of the air pressure in the cylinder 9 to the conical plug 39 is smaller than the thrust of the B spring 38 to the conical plug 39. The push table 6 jacks up the push plate 1, and the push plate 1 leaves the support plate 5 and drives the hinged U-shaped plate A8 to slide upwards; when the A piston 18 continues to move upwards, the push platform 6 pushes one side of the push plate 1 to reach the position of the bulge 15 at the top end of the B support plate 7, the height of the push plate 1 is higher than that of the top of the A support plate 2, and the transverse plate 12 on the top rod 13 is about to reach the horizontal section position of the L-shaped plate A20. The piston 18 continues to move upwards, and due to the limit of the protrusion 15, the push plate 1 swings upwards along the point of contact with the protrusion 15, and the push table 6 and the push plate 1 change from surface contact to line contact; when the push plate 1 swings to a position parallel to the slide carriage 4, the tilt of the push plate 1 is enough to slide the workpiece along the push plate 1 to the slide carriage 4, and the workpiece slides from the slide carriage 4 to the collection box of the workpiece. The collecting box of work piece is placed according to actual demand. When the push plate 1 swings to a position parallel to the slide carriage 4, the horizontal plate 12 abuts against the horizontal section of the L-shaped plate A20, the ejector rod 13 drives the L-shaped plate A20 to move upwards for a certain distance through the horizontal plate 12 along with the continuous upward swinging of the push plate 1, the movement limit of the L-shaped plate A20 on the A slide block 26 is removed, and under the reset action of the A spring 25, the A slide block 26 moves to one side far away from the cylinder body 9 until the air hole B33 and the A hole 28 are not blocked any more. At the moment, the control module controls the air charging device to stop supplying air; the lower end of the L-plate a is opposite to the inclined surface of the a-slider 26.
The air hole B33 on the A shell 27 is completely opened, the air in the cylinder 9 enters the A shell 27 through the hole A28 and emerges from the air hole B33, the piston 18A slides downwards to the initial position along with the continuous reduction of the pressure in the cylinder 9, the push bench 6 drives the push plate 1 to slide downwards after being attached to the U-shaped plate A8, the push plate 1 and the support plate 5 return to the attached state, and the transverse plate 12 on the ejector rod 13 pushes the clamping plate 21 to move downwards for resetting; during the period, the transverse plate 12 drives the clamping plate 21 and the L-shaped plate A20 to move downwards, the lower end of the L-shaped plate A20 extrudes the inclined surface of the A sliding block 26, the air pressure in the cylinder 9 is atmospheric pressure, the A sliding block 26 slides to one side close to the cylinder 9, the air hole B33 and the A hole 28 are blocked, the lower end of the L-shaped plate A20 is clamped on the inclined surface side vertical surface of the A sliding block 26, and the A spring 25 is stretched. The a latch 50 and the B latch 49 move to return to the initial state by the return action of the C spring 51.
And (4) repeatedly ejecting the formed workpiece.
When equipment operation breaks down, when leading to the unable normal compound die sinking of mould, probably the mould still is located push pedal 1, and then causes the unable circumstances that is promoted of push pedal 1. At this time, if the gas of the inflator continuously enters the cylinder 9, the piston 18 a cannot move upwards, so that the gas pressure in the cylinder 9 becomes larger and larger until the thrust of the gas on the conical plug 39 is larger than the thrust of the spring B38 on the conical plug 39; the tapered plug 39 on the B shell 32 is jacked up, the tapered hole 60 is opened, the B spring 38 is compressed, the A fixture block 50 on the telescopic rod 40 in the B shell 32 is extruded and crosses the B fixture block 49 with the inclined surface at the top end, the B fixture block 49 moves towards the direction of the C spring 51, after the A fixture block 50 crosses the B fixture block 49, the B fixture block 49 moves to the position for limiting the A fixture block 50 under the action of air pressure, the B fixture block 49 limits the A fixture block 50 to move towards the cylinder body 9, and therefore it is guaranteed that the tapered plug 39 does not block up the tapered hole 60 any more. The gas in the cylinder 9 enters the B shell 32 from the taper hole 60, the gas is sprayed out from the pneumatic horn 35 along the gas hole on the B piston 43, and the pneumatic horn 35 gives an alarm. After the operator on duty hears the alarm sound, the air charging device is closed, the air charging device stops supplying air, the air pressure in the cylinder body 9 is continuously reduced to the atmospheric pressure, the C spring 51 stretched in the C shell 53 pulls the C piston 52 and the B fixture block 49 to reset to the initial state, the B fixture block 49 does not limit the A fixture block 50, the compressed telescopic rod 40 in the B shell 32 pushes the conical plug 39 to seal the conical hole 60 again, and the A fixture block 50 returns to the initial position closest to the cylinder body 9.
The A fixture block 50 and the B fixture block 49 are matched to act as follows: when the pressure exceeds the threshold value and the thrust of the air pressure in the cylinder body 9 pushes the conical plug 39 open, the B clamping block 49 can limit the A clamping block 50, the conical plug 39 can not be reset to block the conical hole 60 temporarily, so that the air pressure in the cylinder body 9 is instantly reduced and can not be in an ultrahigh air pressure state all the time, and the mechanical damage caused by the fact that the structure above the cylinder body 9 is pushed by the ultrahigh air pressure all the time can be avoided; in addition, the limiting of the fixture block 50A by the fixture block 49B can prevent the tapered hole 60 from being blocked, so that the air in the cylinder 9 can blow the pneumatic horn 35 from the tapered hole 60 and the round hole of the piston 43B to continuously and effectively give an alarm.
In conclusion, the invention has the main beneficial effects that: by arranging the pneumatic alarm horn, the cone plug, the telescopic rod and the spring B, when the equipment is abnormal, the cone plug is pushed open by high air pressure, the pneumatic alarm horn can give an alarm, a person can more easily find that the equipment has a fault, and the alarm sound can be distinguished even in a noise environment; the piston A of the invention adopts negative pressure reset, and the reciprocating motion of the piston A in the cylinder body is realized through the matching of the slide block A and the L-shaped plate A, and the reciprocating motion can be realized only by an inflating device without an air extracting device, thereby reducing the cost. According to the invention, the design of the push disc, the rotating rod, the threaded ring and the rotating disc can adjust the air pressure alarm threshold value according to the weights of different workpieces, so that the workpieces cannot be alarmed when being ejected. The invention has simple structure and better use effect.
