New description: [New technical field] The present invention relates to a mold, and more particularly to a mold having a machine control unit. [Prior Art] Modern industry uses mass production of molds by means of molds. The molds are generally provided with a ejector mechanism for ejecting the formed products and a machine control unit for resetting the ejector mechanism. The machine control unit will eject the mechanism. After the reset signal is transmitted to the machine, the machine issues a control command for the next action. Referring to the first figure, a mold 100' is disclosed. The mold 100' has an upper and lower mold 10' and a contact machine control unit 20'. The contact machine control unit 20' has a body 21. 'The top surface of the body 21' is provided with a resilient piece 22' and a stud 23' located below the elastic piece 22' and spaced apart from the elastic piece 22' by a certain distance. The lower die 10' has an ejecting mechanism 11', and the ejecting mechanism 11' is provided with a pressing block 111' for pressing the elastic piece 22' and a plurality of ejector pins 112'. After the product is cooled and formed, the mold 100' is completely opened, and the ejection mechanism 11' pushes the product out. When the ejection mechanism is reset by the elastic force of the spring 30', the pressing block 111' is pressed against the elastic piece 22' to When the elastic piece 22' is in contact with the protruding post 23', the signal of the main body 21' for resetting the ejection mechanism 11' is transmitted back to the machine through the transmission line, and the machine can issue an operation instruction for the next step of clamping. However, the elastic piece 22' of the contact type machine control unit 20' is prone to permanent deformation after a large number of repeated actions, and the elastic force is insufficient. When the ejection mechanism 11' is not completely reset, the elastic piece 22' has pressed against the protruding column 23'. That is, when the mold 100' is not fully opened, the product is ejected or the ejection mechanism 11' is not fully reset, and the mold clamping 100' is often crushed. [New content] The purpose of this creation is to overcome the deficiencies in the prior art described above, and to provide a mold for a machine control unit of the machine that can accurately sense the state of the ejector mechanism in time. In order to achieve the above objectives, the mold provided by the present invention includes an upper mold, a lower mold and a machine control unit. The lower mold includes a fixing plate, a molding mechanism mounted on the fixing plate, and an ejection mechanism. The front end of the fixing plate defines a mounting groove, and the molding mechanism has a cavity. The machine control unit is fixedly mounted in the mounting slot of the fixed plate and includes a light sensor. As described above, the creation mold senses the reset and unreset state of the ejection mechanism by the light sensor of the machine control unit, and transmits it to the machine of the mold, so that the machine can accurately and timely detect the ejection mechanism. The status, so that the subsequent operation instructions can be correctly issued to prevent the mold from being crushed. [Embodiment] In order to explain in detail the technical contents, structural features, achieved goals and effects of the present invention, the following is a detailed description with reference to the drawings. Referring to the second figure, the original mold 100 includes an upper mold 10, a lower mold 20, and a machine control unit 30 mounted on the lower mold 20. The lower mold 20 includes a fixing plate 21, a molding mechanism mounted on the fixing plate 21, and an ejection mechanism 23. The fixing plate 21 has a plate shape. The fixing plate 21 is provided with a vertical sliding shaft (not shown). The front end of the fixing plate 21 is provided with a mounting groove 211 penetrating vertically and a wiring groove 212 communicating with the mounting groove 211. The molding mechanism includes two side plates 221 vertically disposed on the upper surface of the fixing plate 21 and a lower template 222 fixedly disposed above the two side plates 221. The lower template 222 is provided with a cavity 223. The ejector mechanism 23 is disposed between the two side plates 221. In the present embodiment, the ejector mechanism 23 includes a top plate 23, a spring 232, and a plurality of thimbles 233 vertically affixed to the top plate 231. The front end of the top plate 231 defines a receiving slot 4 M380220 2311. The top plate 231 is sleeved on the sliding shaft of the fixing plate 21 and can move up and down along the sliding axis. The thimble 231 can slide up and down with the top plate 231 and can pass up through the lower template. The 222 extends into the cavity 223. The machine control unit 30 is fixedly mounted in the mounting slot 211 of the fixed plate 21, and includes a mounting plate 31, a light sensor 32, and a transmission line 33. The light sensor 32 is fixed on the fixing plate 21 by the mounting plate 31. The upper portion of the light sensor 32 can be received in the receiving slot 2311 of the lower top plate 231. The light sensor 32 includes a transmitter and a receiver (not shown). A transmission line 33 is connected to the lower end of the optical sensor 32, and the transmission line 33 is placed in the wiring groove 212 of the fixing plate 21. When the mold 100 is completely opened, the ejector mechanism 23 drives the ejector pin 233 to move upward to push the product out, and then the ejector mechanism 23 is reset by the elastic force of the spring 232, and the emitter of the light sensor 32 continuously emits infrared rays. The receiver is always in the waiting signal state. When the light sensor 32 on the fixing plate 21 senses that the upper top plate 231 of the ejection mechanism 23 has a distance therefrom, the upper top plate 231 reflects the infrared rays to the receiver, and the light sensor 32 sends out the signal that the ejector mechanism 23 has been reset and transmits it to the machine through the transmission line 33, and the machine can issue other subsequent control operation commands, that is, mold clamping. In summary, the creation mold 100 senses the ejector mechanism 23 at a certain position by the light sensor 32 of the machine control unit 30, and can accurately detect that the mechanism 23 is transferred to the machine after being reset. The station can accurately and timely detect the state of the ejector mechanism 23, so that subsequent operation commands can be correctly issued to prevent the mold from being crushed.
