Fig. 1-4 is please referred to, the utility model provides a kind of technical solution:

A kind of polishing roll mold ejection mechanism after molding, as depicted in figs. 1 and 2, including lower die holder 1, lower die holder 1 it is upper Several modules 2 are connected at side and close two sides, the top of module 2 is connected with cushion block 3, and the surface of cushion block 3 is connected with lower die 4, lower mold core 5 is fixed at the center of 4 upper end of lower die, and ejecting mechanism 6 is connected at the center of lower mold core 5.

Specifically, the lower mold core 5 and roof platform 60 of the present embodiment are integral using numerical control machining center processing, 5 He of lower mold core Roof platform 60 is all made of mould steel and is made, and with high rigidity, high intensity, wearability and high harden ability, hardenability, makes its knot Structure consolidates durable.

Specifically, offer top pillar hole 10 at the center of lower die holder 1, lower die holder 1, module 2 and cushion block 3 are from bottom to up successively By bolt-through, and bolt is connected through a screw thread with lower die 4, them is made to link into an integrated entity, convenient for fixing.

Further, lower thimble 62, upper plate 63 and lower roof plate 64 are placed between module 2, and it is empty to provide effective activity Between, convenient for ejection polishing roll, top pillar hole 10 and ejecting mechanism 6 make motive force be in line outflow in coaxial line cooperation.

In addition to this, die hole 50, i.e. polishing roll forming cavity, the center of die hole 50 are offered at the center of 5 upper end of lower mold core Place offers centre hole 500, the outside of centre hole 500 and is located at 50 bottom surface of die hole and is equipped with several convex blocks 51,5 upper end of lower mold core Corner be equipped with mold core counterbore 52, convenient for fix.

In specific implementation, since polishing roll is equipped with thickly dotted stomata and cooling hole, make traditional thimble of its mold Do not eject a little, in order to avoid traditional thimble deforms hole location, may capping polishing roll, the present inventor to ejecting mechanism 6 make It improves out, as a kind of preferred embodiment, as shown in Figure 3 and Figure 4, ejecting mechanism 6 is successively arranged roof platform 60, welding from top to bottom Upper thimble 61 below at 60 center of roof platform, is connected to lower 62 lower end of thimble at the lower thimble 62 for being connected to upper 61 lower end of thimble Upper plate 63 and the lower roof plate 64 that is set to immediately below upper plate 63.

Specifically, offering die cavity 40 at the center of 4 upper end of lower die, die cavity 40 is bolted to connection with lower mold core 5, Lower mold core use it is long, convenient for by Bolt dismantling replacement lower mold core 5.

Further, roof platform 60 include cylinder ring 600, the cross-rib 601 and cross-rib 601 that connect on the inside of cylinder ring 600 The cylindrical piece 602 connected at center, roof platform 60 and convex block 51 are engaged by clamping, and increase it with polishing roll contact surface after molding, It avoids capping or influences its Forming Quality.

In addition to this, the bottom end of upper thimble 61 offers threaded hole 610, and upper thimble 61 is slidably connected with centre hole 500, under The bottom end of thimble 62 is welded with boss 620, and the outside on lower 62 top of thimble is equipped with screw thread, lower thimble 62 at 63 center of upper plate The counterbore 630 offered is mating, and the outer sheath of lower thimble 62 is equipped with spring, so that ejecting mechanism 6 resets, upper plate 63 It is bolted to connection with lower roof plate 64, is fixed on down lower thimble 62 in counterbore 630, this connection type is convenient for ejecting mechanism 6 installation and removal.

It is worth noting that, upper thimble 61 sequentially passes through lower mold core 5 and lower die 4, lower thimble 62 through cushion block 3 and with upper top Needle 61 is connected through a screw thread, and cushion block 3 plays position-limiting action to upper thimble 61.

The polishing roll of the present embodiment mold ejection mechanism after molding when in use, when in die hole 50 polishing roll molding Afterwards, it is obtained after the thrust that top pillar hole 10 is transmitted in lower roof plate 64, by upper plate 63, lower thimble 62 and upper thimble 61 thrust It reaches in roof platform 60, at this point, roof platform 60 pushes plastic polishing roller to be detached from die hole 50, since the structure of roof platform 60 makes polishing roll quilt Whole ejection, after thrust is removed, roof platform 60 can be reset in die hole 50 under the recoil of spring effect outside lower thimble 62, quasi- Standby next polishing roll forms, and the utility model effectively protects polishing roll after molding, avoids it by bursting and capping, greatly Forming Quality is improved greatly.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Be only the utility model preference, be not intended to limit the utility model, do not departing from the spirit and scope of the utility model Under the premise of, the utility model also has various changes and improvements, these changes and improvements both fall within claimed it is practical In novel range.The protection scope of the present invention is defined by the appended claims and their equivalents.
