The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further, so that clearerly understand the utility model technical thought required for protection.
As shown in Figure 1, 2, 3, be the automatically reset row of a kind of mechanical type of the utility model position ejecting mechanism, comprise lower bolster 002, be positioned at lower bolster 002 top cope match-plate pattern 001, be installed in lower bolster 002 upper surface and can be along the row position device that the length direction of lower bolster 002 slides, described row position device comprises the holder that is slidably mounted on the lower bolster 002, is fixed on glue position mold insert 003, thimble group plate on the holder front end.The back-up block 004 concrete, that described holder comprises pedestal 005, is fixed together with pedestal 005; Described glue position mold insert 003 is fixed on the back-up block 004 by screw 008.Described thimble group plate comprises thimble panel 007 and the Ejector Retainer Plate 006 that is synchronized with the movement, and described thimble panel 007 is positioned at the rear of glue position mold insert 003.Form the free gap district between the rear wall of the front side wall of described holder and glue position mold insert 003, described thimble group plate is installed in the district of free gap movably, and its moving direction is consistent with the length direction of lower bolster 002; Be provided with compression spring 010 between described thimble group plate and the holder, and the flexible direction of this compression spring 010 is consistent with the length direction of lower bolster 002; On the described thimble group plate a plurality of thimble tubes 013 are arranged fixedly, the front end of this thimble tube 013 passes from the perforation of glue position mold insert 003, a plurality of and thimble tube 013 thimble 012 is one to one fixedly arranged on the described holder, and this thimble 012 interts in the thimble tube 013 corresponding with it; The front end of described thimble tube 013 is provided with the locating hole that passes for thimble 012; The lower surface of described cope match-plate pattern 001 is provided with brace 014, and this brace 014 is from up to down gradually towards tilting away from cope match-plate pattern 001 centerline direction; Holder is provided with the skewed slot that is complementary with brace 014; The front side wall that also is provided with on the described cope match-plate pattern 001 for pushing tow thimble group plate compresses the reset surface 015 that spring 010 is in compressive state so that thimble group plate resets and then makes towards holder front side wall direction.
Preferably, be provided with guide post 009 between the rear wall of described holder and glue position mold insert 003, described thimble group plate is provided with first through hole that passes for guide post 009, so that guide effect is carried out in the slip of thimble group plate.Bracing piece 011 is fixedly arranged on the front side wall of this holder, and described thimble group plate is provided with second through hole that passes for bracing piece 011, and the front end of this bracing piece 011 withstands on the rear wall of glue position mold insert 003, to prevent 003 distortion of glue position mold insert.
In actual production process, the die sinking step of mould such as Fig. 4 are to shown in Figure 6, to move on the cope match-plate pattern 001 earlier, row position device is moved to the left under the acting in conjunction of brace 014 and skewed slot, at this moment, holder in the device of row position and glue position mold insert 003 are all to left movement, but because compression spring 010 is in compressive state when the mould matched moulds, and along with the mobile compression spring 010 of holder is stretched out recovery, and make thimble group plate under the elastic force effect of compression spring 010, remain on initial position, thereby thimble tube 013 is still withstood on the product to guarantee that product can not be bonded on the glue position mold insert 003; After this, move on cope match-plate pattern 001 continues, thimble group plate is moved along with the slip of row position device, makes thimble tube 013 leave product, finishes and looses core.
The matched moulds step of mould such as Fig. 7, Fig. 8, shown in Figure 4, earlier brace 014 is interted in skewed slot, at this moment, brace 014 rigidly connects tactile skewed slot, thimble group plate and cope match-plate pattern 001 are in the state of avoiding, and constantly moving down along with cope match-plate pattern 001, row position device moves right, thereby and reset surface 015 is contacted with the front side wall of thimble group plate impel thimble group plate to move to realize that towards holder front side wall direction it resets to its applied thrust, and make compression spring 010 be in compressive state in the roof pressure effect of thimble group plate.
Glue position mold insert 003 move and with the injecting products disconnecting process in, by utilizing the roof pressure effect of thimble tube 013, can guarantee that injecting products can not be bonded on the glue position mold insert 003, thereby improve the depanning quality of product; And the maximum moving distance by row position device rationally is set and the shape of glue position mold insert 003 can make it be applicable to and produce that area is big, the dark more injecting products of position of bone post, enlarge its scope of application; In addition, can also utilize the reset surface 015 of cope match-plate pattern 001 to realize automatically reseting of thimble group plate, therefore, need not to be equipped with the equipment that other are used for providing to thimble group plate tractive force, be conducive to save cost.
Above-mentioned embodiment only is preferred embodiment of the present utility model; can not limit the scope of the utility model protection with this, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
