In order to ensure the stability during cutting, the insert injection molding product 7 on the product positioning tool 34 needs to be pressed and positioned during cutting; therefore, the slide block structure 632 is further provided with a guiding and limiting shaft structure 636 (a guiding shaft and a limiting clamp spring for preventing the guiding shaft from sliding downwards) in a sliding manner, the bottom end of the guiding and limiting shaft structure 636 is provided with a pressing block structure 637, and the guiding and limiting shaft structure 636 is sleeved with an elastic piece 638; one end of the elastic member 638 abuts the slider structure 632, and the other end abuts the press block structure 637. Wherein, reserve the notch of dodging cut-off knife fixed block 634 in the middle of briquetting structure 637, prevent the motion condition of interfering.
The following briefly describes the cutting and recycling process of the material bundle which is completed by the product positioning device 3 and the pouring gate material bundle cutting device 6; before cutting, the driving part 33 drives the stand 32 to slide to a cutting station (namely, below the handle cutting mechanism 63), and the pin positioning mechanism 62 positions the stand 32. When cutting, the first vertical driving piece 351 drives the flexible chopping board 353 to move upwards to be abutted with the pouring gate material handle 71, and supports the pouring gate material handle 71 to assist subsequent cutting; then, the vertical driving piece 633 in the material handle cutting mechanism 63 drives the sliding block structure 632, the cutter fixing block 634, the guiding limiting shaft structure 636 and the pressing block structure 637 to move downwards simultaneously, when the pressing block structure 637 presses and fixes the insert injection molding product 7 on the product positioning tool 34, the sliding block structure 632 and the cutter fixing block 634 continue to move downwards, so that accurate stable cutting of the gate material handle 71 is realized (the material handle cutting mechanism 63 presses the insert injection molding product 7 and then cuts the gate material handle 71). The material handle is recovered after cutting, and the first vertical driving piece 351 drives the flexible cutting board 353 and the pouring gate material handle 71 to move downwards to an initial position (recovery station); the gate material holders 71 on the flexible anvil 353 are now aligned with the guide channels 321 and the blowing structure 37 is operated to blow the gate material holders 71 along the respective guide channels 321 into the recovery structure 36.
While the gate material handle 71 is recovered, the driving component 33 drives the stand 32 to slide to the product/film picking and placing station in a direction away from the cutting station (in other embodiments, after the gate material handle 71 is recovered, the driving component 33 drives the stand 32 to slide to the product/film picking and placing station in a direction away from the cutting station, which is not limited herein); after recycling, the first vertical driving piece 351 and the second vertical driving piece 352 sequentially move upwards to drive the flexible cutting board 353 to eject the insert injection molding product 7 out of the product positioning tool 34 (the pressing block structure 637 presses and fixes the insert injection molding product 7 on the product positioning tool 34, and then cutting is started, so that when a product is taken out, the insert injection molding product 7 needs to be ejected out of the product positioning tool 34), and the external equipment takes away the insert injection molding product 7 to swing.
In summary, the invention can replace manual work, automatically complete insert feeding, accurate butt joint with an injection molding machine, film coating and cutting of a pouring gate handle; the product precision is ensured, the utilization rate is ensured, the working efficiency is improved, and the stability of the working quality is ensured.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
