Abstract
The utility model provides a mould closing protection controller of an injection molding machine. The mould closing protection controller comprises a mould closing protection detection circuit connected with a main circuit of the injection molding machine, wherein an input end of the mould closing protection detection circuit is connected with a laser transmitter and a photoelectric receiver which are mated with each other; the laser transmitter and the photoelectric receiver are fixedly mounted on the two sides of a product de-molding position to form a product de-molding detection device. According to the mould closing protection controller provided by the utility model, the detection precision of the laser transmitter and the photoelectric receiver is high; if a product is not completely de-molded and one part of the product is stuck and remained on a mould, a laser path is blocked and the mould closing protection detection circuit can detect a corresponding signal, so as to further stop the main circuit of the injection molding machine from transmitting a mould closing instruction and avoid damaging the mould; the safety protection effect is obvious and the detection is sensitive; the structure is simple and reasonable and the cost is low; the mould closing protection controller is easily mounted on and applied to the injection molding machine.
Description
Technical field: the utility model relates to the clamping controller of a kind of injection machine, particularly injection machine.
Background technology: the mould of injection machine needs ceaselessly mold-closing injection, separation, product stripping, matched moulds more in the course of the work, if product stripping is not thorough, part adhesion remains on mould, again likely causes when matched moulds mould to damage, and this is more obvious on precision die.Matched moulds protective device on present injection machine is generally fence operation personal security, avoids mould to clash into injury, and the matched moulds damage that product stripping is not thoroughly caused does not detect protection effect substantially.
Summary of the invention: for the deficiencies in the prior art, the utility model provides a kind of injection machine matched moulds protection controller that can testing product demoulding state.
The utility model comprises the matched moulds protection testing circuit being connected with the main circuit of injection machine; the input of this matched moulds protection testing circuit is connected with generating laser and the photelectric receiver of pairing; generating laser and photelectric receiver are fixedly installed in the both sides of product stripping position relatively, form product stripping detector.
Generating laser in the utility model and photelectric receiver accuracy of detection are higher; if product stripping is not thorough, part adhesion remains on mould, can cut off laser path; make matched moulds protection testing circuit corresponding signal be detected; and then stop the main circuit of injection machine to send matched moulds instruction, and avoid mould to damage, safety protective effect is obvious; detect sensitive; and simple and reasonable, cost is low, easily on injection machine, installs and promotes.
Further illustrate the utility model below in conjunction with drawings and Examples.
Accompanying drawing explanation: Fig. 1 is the main structure schematic diagram of embodiment.
Fig. 2 is the workflow block diagram of embodiment.
Fig. 3 is the theory diagram of matched moulds protection testing circuit.
The specific embodiment: as shown in Figure 1; the main circuit of matched moulds protection testing circuit and injection machine is connected; the input of this matched moulds protection testing circuit is connected with generating laser 1 and the photelectric receiver 2 of pairing; generating laser 1 and photelectric receiver 2 are fixedly installed in the both sides of product stripping position relatively, form product stripping detector.Because product is generally to move disengaging with the dynamic model part of mould 3, thus generating laser 1 and photelectric receiver 2 also with relative fixed installation of dynamic model part of mould 3.And size and the form categories of mould 3 are more, it is multipair that part mould 3 needs generating laser 1 and photelectric receiver 2 to arrange, and is installed on the corresponding position of both sides, product stripping position, so just can the whether thorough demoulding of complete detection product.
When work, as shown in Figure 2, if the light that generating laser 1 is launched is received by photelectric receiver 2; the input of matched moulds protection testing circuit is normal signal; what export to the main circuit of injection machine is also normal signal, and mould 3 is subject to the main circuit instruction control of injection machine, normally matched moulds.If there is the portioned product demoulding not thorough; adhesion remains on mould 3; there is the light between any a pair of generating laser 1 and photelectric receiver 2 to be cut off; to the input of matched moulds protection testing circuit is abnormal signal; matched moulds protection testing circuit is to the main circuit output fault-signal of injection machine; stop the main circuit of injection machine to send matched moulds instruction, mould 3 cannot matched moulds.General matched moulds protection testing circuit is also connected with warning circuit, in the time of output fault-signal, can also have the form such as sound, demonstration to remind operating personnel.
The basic principle circuit of matched moulds protection testing circuit is more conventional; can there is different version; the matched moulds protection testing circuit of the present embodiment as shown in Figure 3; include photoelectric detective circuit, matrix combiner circuit, comparison amplifying circuit, also include test set number simultaneously and switch display circuit and timing circuit.Photoelectric detective circuit receives signal, by matrix combiner circuit carry out signal synthetic after, through relatively amplifying circuit output.Test set number switches display circuit can switch the group number of selecting generating laser 1 and photelectric receiver 2, and provides demonstration.Timing circuit can be controlled the effective time limit of detection.
