Description

Counter mould

Technical Field

The invention relates to the technical field of relevant products of molds, in particular to a counter mold.

Background

The mould counter is mainly used for counting the number of produced moulds, determining the number of products and also fixing the number of the maintained moulds.

The mold product supplier usually uses a pair of molds for exceeding the service life due to the cost when producing products, which can cause the reduction of the product quality, so the product client can check the mold maintenance and the using times of the suppliers, and the mold maintenance book and other tools have no uniqueness, so the mold counter can be produced at the same time, but most of the existing mold counters can be disassembled and replaced, although the existing mold counters with non-disassembly are also provided, such as the mold counter of Chinese patent publication No. CN 104636796B, which detects the disassembly action through the locking switch, displays and locks the counter when detecting the disassembly action, although the disassembly can be detected to a certain extent, the locking switch can pop up when disassembling, if the locking switch is pressed against by a hard object from the gap when disassembling, the locking switch can not be detected, thus resulting in a distorted count, as well as a risk of falsifying. To this end, we propose a counter die.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-7, the present invention provides a technical solution: the utility model provides a counter mould, includes shell 1 and lower shell 2, goes up shell 1 and lower shell 2 and all adopts thermal insulation material to in the electric elements to inside protects, go up 1 fixed surface of shell and be connected with display screen 3, fixedly connected with control circuit board 4 in the shell 2 down, it is provided with soon to detection mechanism 5 on shell 1 and lower shell 2 pass through screw fixed mounting and screw to go up, control circuit board 4's one end is provided with first inductor 6, just the one end that lower shell 2 is close to first inductor 6 is connected with count switch 7, counts mould production by count switch 7, and after the mould was installed to the device, soon to detection mechanism 5 then can carry out the detection of the screw soon that lasts to the mould, so that prevent disassembly, thereby cause false information.

It includes shell body 8 to revolve detection mechanism 5, the inboard fixed surface of shell body 8 is connected with saw ring gear 9, saw ring gear 9 inboard is provided with ratchet 10, spout 11 and fixed 12 sliding connection at the inside solid fixed ring of shell 2 down have been seted up in the outside of shell body 8.

The ratchet 10 includes a ratchet ring 13, a plurality of sets of latch blocks 14 are rotatably connected to an outer surface of the ratchet ring 13, the latch blocks 14 are connected to a first spring 15 disposed on the outer surface of the ratchet ring 13, an inner surface of the ratchet ring 13 is connected to a screw through an internal thread, the first spring 15 is connected in one of embodiments, and the form of the first spring is not limited to a spring, and the first spring can be fixed to both sides of the latch blocks 14 through a spring plate, so as to reset the latch blocks.

The turning direction detection mechanism 5 mainly judges the turning direction of the screw through the movement between the ratchet wheel 10 and the sawtooth ring 9, when the screw is installed, the screw rotates in the forward direction, because the screw is in threaded connection with the inner surface of the ratchet ring 13, certain locking force is provided, the ratchet ring 13 can rotate along with the screw, when the ratchet ring 13 rotates in the forward direction, the back surface of the fixture block 14 can slide with teeth on the saw gear ring 9, the first spring 15 is compressed, the circulation is repeated, the outer shell 8 cannot be driven, when the screw rotates in the reverse direction, the fixture block 14 can form a clamping position with the teeth on the sawtooth ring 9 under the action of the first spring 15, and therefore the outer shell 8 is driven to rotate.

The outer shell 8 is connected to the fixed ring 12 in a rotating manner, so that the rotating direction detection mechanism cannot displace in the vertical direction, and the pointer 16 on the outer side of the outer shell 8 is used for instruction conversion, and mechanical action is converted into a digital signal which is transmitted to the control circuit board, so that the corresponding signal is responded.

The set screw setting of casing is three groups at least to in order to carry out effective fixed to the device, this embodiment shows that four screw fixation groups, and the group number that sets up to detection mechanism 5 soon is two sets of at least, in order to carry out effectual detection, when the quantity is less than two sets of, just can be at the situation that a set of screw is not demolishd and rotate the device down, thereby make count switch 7 not contact the movable mould or the cover half of mould, thereby make the count distortion.

The device is installed at the movable mould or cover half lateral wall, contacts the pressure piece on the count switch 7 and extrudes when the mould carries out the compound die, carries out mechanical signal conversion into digital signal by first inductor 6 equally after pressing to control display screen 3 through control circuit board 4 and change the count figure, after the mould die sinking, the pressure piece then resets under the effect of second spring 18, so that carry out reciprocal circulation and detect.

At least two groups of LED lamps 20 are arranged on the surface of the upper shell 1, and are used for displaying the position of the pointer 16, the screw is loosened under a long-term fixed natural state, and therefore, the screw can slowly rotate reversely, so that the pointer 16 approaches to the position of the forming switch 21, therefore, the screw is induced in advance by arranging the second sensor 19, the second sensor 19 is a proximity sensor, specifically a Hall sensor, and is used for giving a flashing alarm through a group of LED lamps to remind maintenance personnel to fasten, when the personnel detach the screw, the pointer can contact the travel switch 21, the travel switch 21 is positioned on a rotating path of the outer end part of the pointer 16, so that the forming switch 21 can be touched, and under further rotation, the pointer 16 can be pulled to send a signal to the control circuit board 4, so that the conversion from a mechanical to an electronic signal is completed, the control circuit board 4 sends a stop and locking signal to the counter, the control circuit board 4 locks the count on the display screen 3 permanently and controls the group of LED lamps 20 to display through the control circuit board 4, so as to avoid misinterpretation of the stop of the count of the counter (for example, the stop of the count caused by a circuit failure inside the device, which is not the stop of the count caused by manual disassembly, and the group of LED lamps 20 is used as a judgment basis).

The detection structure of the whole device is positioned in the upper shell 1 and the lower shell 2, and the detection structure cannot be detached after being installed, so that the risk of artificial interference and counterfeiting is avoided, the number of counted moulds is more real, and the quality of products is guaranteed.
