INSTRUCTION DESCRIPTION (2) An air passage 232 that is open and permeable to external air compression. When the airflow is blown in through the air passage 232 and ejected from the bottom end of the blanking hole 231, a low pressure is generated, and the air in the die hole 24 is taken out to form a downward suction force, so that the scrap 31 can be smoothed. The ground is passed through the blanking hole 231 # to the external waste collecting bucket. The introduction of the compressed air into the blanking hole by the air passage 232 has a partial use effect, but since the thickness of the lower die holder 23 is large, the processing of the air passage 232 is not easy, and further, the blanking hole 231 is provided. The velocity of the airflow ejected from the bottom outlet is usually not fast enough, so that the suction force that can be generated is not enough. Or some improvement measures are directly connected to the suction device at the bottom end of the blanking hole 231 of the lower die holder to generate suction. The installation space provided under and around the machine is quite limited. The installation of unfavorable vacuuming equipment causes time-consuming and labor-intensive lack of assembly, and it adds a lot of cost. SUMMARY OF THE INVENTION The present inventors have made it possible to study and analyze the present invention in view of the above. Therefore, the main object of the present invention is to provide a suction device for a mold, which can form an air suction path and a nozzle opening intersecting the blanking hole in the blanking hole of the lower die holder, so that the feeding is performed. The gas in the blanking hole φ can be ejected from the nozzle opening at a higher speed, thereby facilitating the smooth discharge of the waste generated by the press working, and having a simple structure and a favorable processing for the air passage. The present invention is a specific structure and technical means for achieving the above objects and other effects, comprising a lower die holder having a blanking hole and at least one suction pin mountable in the blanking hole of the lower die holder; wherein, the lower die holder Internal opening with connectivity to the outside

Description of the Invention (6) A nozzle opening 56 is formed between the bottom 53 of the pin and the support member 6; that is, the gas flow path 52 is at the suction pin 5. The bottom portion reduces the amount of the gap, and the inclined surface 54 at the bottom end of the suction pin 5 provides a passage for the gas to flow out, so that the entire circumference of the bottom end of the suction pin 5 forms a nozzle opening 56 which enables the gas to be ejected at a high speed. Referring to the sixth embodiment, an embodiment of the present invention for use on a mold is shown, in which a lower pad 22 mounted on the upper side of the lower die holder 3 is pressed at the top end position of the suction pin 5 to position the suction pin 5; As shown in the three figures, when the external compressed air is sent through the air passage 42, the top end of the blanking hole 41, the longitudinal groove 52 of the peripheral wall of the suction pin 5, and the nozzle from the bottom end of the suction pin 5 are flowed downward. The port 56 is ejected at a high speed to form an intake path that intersects the blanking hole 41. As indicated by an arrow 57 in the first figure, the suction path formed by the low pressure will be generated below the shaft hole 51 of the suction pin 5. The downward suction force causes the air in the blanking hole 41 and the die hole 24 to be taken out by the suction force to be mixed and discharged, thereby causing the die-formed waste material 31 to be discharged very smoothly. Referring to the seventh embodiment, in another embodiment of the present invention, a ring groove 58 is disposed at a suitable portion of the peripheral wall of the suction pin 5, and an air passage 42 communicating with the ring groove 58 is defined in the lower die holder 4. Then, the gas blown into the air passage 42 can be directly moved downward from the longitudinal groove of the peripheral wall of the suction pin 5 without being transmitted through the top end of the blanking hole 41, and can be ejected at a high speed from the nozzle opening 56 at the bottom end of the suction pin 5. The suction path 57 formed to intersect the blanking hole 41 is used to suck out the waste formed by the die. Referring to the eighth and ninth embodiments, a second embodiment of the present invention is shown in which the suction pin 5 has a head portion 5 9, and the lower mold base 4 has a length of 1286066. 5. Description (7) The hole inlet 4 11 end is enlarged with a slot 4 丨 4 like a fish eye hole for providing the positioning position of the head 59 of the suction pin 5, and a push-out slope is opened on the inner wall of the bottom section of the blank hole 41. The neck portion 43 is provided to provide the suction bottom portion 53 of the suction pin 5 to form a close fitting, so that the bottom portion 53 of the suction pin and the inner wall of the blanking hole 41 can also form a high-speed gas discharge. The nozzle opening 56 and the suction passage 57 intersecting the blanking hole 41 serve to suck out the die formed waste. According to the suction device formed by the invention, not only the structure of the suction pin and the support member is simple, the installation is convenient, and the processing of the air passage is also relatively easy, in particular, the waste formed by the die can be discharged very smoothly to achieve the invention of the first invention. Design purpose and implementation effect. Therefore, the present invention has a considerable improvement in efficacy, and is a progressive and industrially usable invention, and a patent application is filed according to law. + In the foregoing specification, only the preferred embodiments of the invention have been described. According to the design spirit of the present invention, various changes or modifications can be made. For example, the support member is not limited to the screw member, and the through hole of the screw portion is broken, and the shape is not limited to a regular hexagon, and other variations are modified within the equivalent technique. It is also obvious that those skilled in the art can make obvious substitutions and modifications to those skilled in the art, and will still be incorporated in the scope of the claimed invention.
