The anti-error feeding detection apparatus of automated insert mould
Technical field
The present invention relates to a kind of checkout gear, relate in particular to the anti-error feeding detection apparatus of a kind of automated insert mould, belong to injection mold product technical field.
Background technology
At present, it is detection method conventional in continuous mould that step pitch detects, and is mainly that the position of sending into by detection material strip judges whether mould can carry out further work.Traditional step pitch detection method is correcting hole detection, and whether described correcting hole detection is correct by detecting the position that the position in correcting hole judges that material strip sends into.But the problem that this detection method exists is: 1, between test pin and correcting hole, have certain gap, when there is small deviation in correcting hole, can not detect; 2, test pin could start to detect (when lathe has started to decline, detecting) in the time pressing close to material strip, and because lathe exists inertia, detection can only be controlled lathe and stop, and can not control the position that lathe stops, thereby easily causes mould closed under misdelivery state; If have vacant position position between 3 correcting holes, in the time that this position is arrived in misdelivery, test pin also can think that feeding is correct by mistake by vacant locations, thereby erroneous judgement easily occurs to detect.The problem that traditional detection method exists directly affects the accuracy that mould detects, and anti-stopping materials strip that can not 100% send wrong position and the mould that causes damages.Existing step pitch detects and has that precision is low, die life is short, safeguard the technical problems such as frequent.
In view of this, be necessary to provide a kind of novel automatic defect preventing feeding detection apparatus, to address the above problem.
Summary of the invention

Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the anti-error feeding detection apparatus 100 of automated insert mould of the present invention, it is connected with board (not label), for detection of the position of inserts 60.Described inserts 60 comprises that order is arranged in the identical some guide holes 61 of diameter of described inserts 60 1 sides, and described some guide holes 61 are arranged on same straight line, and a side of described inserts 60 also stretches out and is formed with some pins (not label).In present embodiment, two corresponding inserts 60 can close up the front die holder and the rear die holder that form mold cavity 63 by the cooperation of both some pins, raw material enters in mold cavity 63 by plup inlet, after mold injection molding, two die holders separately, can be by the product after moulding by the interior taking-up of mold cavity 63.
As Fig. 2 and in conjunction with as shown in Fig. 1, the anti-error feeding detection apparatus 100 of automated insert mould of the present invention comprises: limiting plate 10, offers some accepting grooves (not label) on described limiting plate 10; Test rod 20, described test rod 20 comprise protrude into described accepting groove Part I 21, can stretch into pilot pin 23 in described inserts 60 guide holes 61 and the protuberance 22 between described Part I 21 and described pilot pin 23; Optoelectronic switch 30, is provided with the receiving space 31 stretching into for described Part I 21 in described optoelectronic switch 30; And back-moving spring 40, described back-moving spring 40 is located on described Part I 21, and be held between described accepting groove inwall and described protuberance 22, on wherein said limiting plate 10, be also provided with the through hole (not label) being communicated with described accepting groove and receiving space 31, the diameter of described through hole is less than the diameter of described back-moving spring 40, thereby described back-moving spring 40 is limited between described accepting groove inwall and described protuberance 22.
In present embodiment, in described optoelectronic switch 30, be provided with optical transmitting set (not shown) and optical receiver (not shown), described receiving space 31 is between described optical transmitting set and described optical receiver, and described receiving space 31 comprises the first space (not label) and second space (not label), second space described in present embodiment is positioned at the below in described the first space, the both sides in described the first space are respectively equipped with described optical transmitting set and described optical receiver, the free end that the both sides of described second space are not provided with described optical transmitting set and described optical receiver and described test rod 20 Part I 21 is contained in described second space, described optoelectronic switch 30 is grooved.The anti-error feeding detection apparatus 100 of described automated insert mould also comprises screw 50 fixing with described limiting plate 10 described optoelectronic switch 30 and is connected the Part II 24 of described protuberance 22 and described pilot pin 23, the diameter of described Part II 24 is less than the diameter of described protuberance 22 and is greater than the diameter of described pilot pin 23, and the diameter of described pilot pin 23 is less than the diameter of described some guide holes 61 simultaneously.
The anti-error feeding detection apparatus 100 of automated insert mould of the present invention is in the time that mould carries out matched moulds, and described test rod 20 detects the position of described inserts 60.In the time there is skew and side-play amount and exceed the correcting scope of described pilot pin 23 in the self-feeding position of described inserts 60, the pilot pin 23 of described test rod 20 cannot pass through the guide hole 61 of described inserts 60, described pilot pin 23 is obstructed the free end of described Part I 21 is retreated to the first space of described receiving space 31 under the compressed state of supporting of described back-moving spring 40, and the light that described optical transmitting set is sent reflection, make described optical receiver cannot receive the light that described optical transmitting set sends, described optoelectronic switch 30 is blocked, described optoelectronic switch 30 outputs stop matched moulds signal to described board, thereby controlling described board moves, realize the effect of prevention pressing mold, when the self-feeding position of described inserts 60 through adjust correct after, described test rod 20 is under the effect of described back-moving spring 40, described pilot pin 23 stretches in the guide hole 61 of described inserts 60, the free end of described test rod 20 Part I 21 is contained in the second space of described receiving space 31 again, make described optical receiver can receive the light that described optical transmitting set sends, described optoelectronic switch 30 outputs can be given described board by matched moulds signal, thereby control described board generation corresponding actions.
In present embodiment, the free end of described test rod 20 Part I 21 is to protrude in the second space of described receiving space 31, and in other embodiments, described optical transmitting set and described optical receiver can be arranged at the both sides of described second space, and the free end of described test rod 20 Part I 21 does not protrude in described second space.What the optoelectronic switch 30 in present embodiment adopted is the grooved optoelectronic switch that is provided with optical transmitting set and optical receiver, also can adopt in other embodiments the optoelectronic switch of other kinds, for example: inside is provided with the optoelectronic switch of sensing chip, thus test rod 20 can be by controlling optoelectronic switch output corresponding signal with whether contacting of sensing chip.
