Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical solution of the present invention, the following description is made by using specific examples.
Examples
Referring to fig. 1 and 2, the present invention provides a hot runner capable of detecting movement of a valve needle, including a mold body 100, a cylinder cover 200, a cylinder body 300, a piston 400, a piston guide rod 500 and a valve needle 600, a through hole is provided at a position on the cylinder cover 200 corresponding to the piston 400, a groove is provided at a position on the mold body 100 corresponding to the piston 400, an electromagnetic induction device 700 is provided in the groove, a magnet 900 is provided at a end of the piston 400 close to the electromagnetic induction device 700, and the electromagnetic induction device 700 is electrically connected to an electromagnetic induction display 110.
The utility model discloses a theory of operation: when the piston 400 reciprocates and moves upward, the piston passes through the through hole of the cylinder head 200, the magnet 900 on the upper part of the piston 400 is magnetically cut with (or close to) the electromagnetic induction device 700, the electromagnetic induction device 700 generates corresponding current, and the electromagnetic induction display 110 converts the corresponding pressure into corresponding pressure and records the pressure. Of course, if the relationship between the current and the pressure is determined by experiment, the magnitude of the pressure can be calculated by obtaining the magnitude of the current. The pressure is used for judging whether the pressure is normal or not, so that whether the air cylinder works normally or not is judged. Of course, the magnitude of the overcurrent can be directly used to directly judge whether the cylinder is working normally. Meanwhile, whether the valve needle acts or not can be monitored in real time.
The utility model discloses in, still be equipped with lip block 800 in the recess, lip block 800 is located between electromagnetic induction device 700 and the cylinder cap 200, and lip block 800 middle part is equipped with the through-hole relative with piston 400. The support spacers 800 are used to support the electromagnetic induction device 700 fixed between the cylinder head 200 and the die body 100. The through hole in the middle of the lip block 800 allows the piston 400 to pass through, and the magnet 900 on the top of the piston 400 comes into contact with or close to the electromagnetic induction device 700.
In the present invention, the electromagnetic induction device 700 is provided with an electromagnetic induction circuit on a fixing member. The electromagnetic induction display 110 is connected to an electromagnetic induction circuit.
The utility model discloses in, still include that the heat is chewed, the heater, is chewed the point, is pressed the cap.
The utility model discloses in, still include the holding ring, inject the mouth point, heater, inject and chew the body. For injecting the material.
The utility model discloses in, the cloud ware is connected to electromagnetic induction display 110 electricity.
The utility model discloses well magnet 900 includes permanent magnet and electro-magnet.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
