Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1 to 5: mould with inboard large tracts of land back-off demoulding mechanism of product, including mould benevolence 1, still include shaping slider 2 and main slider 3, the left surface of mould benevolence 1, the right flank of mould benevolence 1 all is equipped with a plurality of inserts grooves, wherein, a plurality of inserts grooves that are located the same side arrange into one row along 1 length direction of mould benevolence, and reserve the interval between two adjacent inserts grooves, it is equipped with shaping slider 2 to inlay in every inserts groove, be equipped with spout 21 on the shaping slider 2, main slider 3 includes sliding part 31, sliding part 31 activity is located in spout 21, be equipped with its side of drive on the main slider 3 and move oblique guide pillar 4, shaping slider 2 is including the bellying 22 that restriction sliding part 31 side moved.
The forming slide block 2 is in an L shape, the forming slide block 2 is in an integrated structure and comprises a forming section 23 and a connecting section 24, the forming section 23 is perpendicular to the connecting section 24, the forming section 23 is arranged in the insert groove, the sliding groove 21 is arranged on the connecting section 24, and the protruding portion 22 is arranged on the sliding groove 21.
Still include framed 5 and lower framed 6, framed 6 under mould benevolence 1 locates, goes up framed 5 and is equipped with the shaping die cavity, and the shaping die cavity constitutes the die cavity with framed 6 compound die down, and the linkage segment 24 of main slider 3 and shaping slider 2 all is located framed 6 down.
An inclined guide hole is arranged on the main sliding block 3, an inclined guide post 4 is movably arranged in the inclined guide hole, and the upper end of the inclined guide post 4 is fixedly connected with the upper die frame 5.
The mold insert 1 is formed by splicing two molding inserts.
Demolding process of the face shell 111: the upper die frame 5 is separated from the lower die frame 6 through an external driving device (oil cylinder), the upper die frame 5 drives the inclined guide post 4 to gradually leave the main slider 3, in the process, the inclined guide post 4 drives the main slider 3 to move laterally (the left main slider 3 translates leftwards and the right main slider 3 translates rightwards), after the main slider 3 translates for a distance S, the sliding part 31 of the main slider 3 barbs on the lug boss 22, then, under the continuous action of the inclined guide post 4, the main slider 3 drives the forming slider 2 to move laterally (the left main slider 3 drives the left forming slider 2 to translate leftwards and the right main slider 3 drives the right forming slider 2 to translate rightwards) until the tail part of the main slider 3 abuts against the edge of the lower die frame 6, the main slider 3 stops translating, and the left side plate 113 and the right side plate 114 of the face shell 111 are pried (because the face shell 111 is made of plastic, has certain elasticity, can bear small deformation and can not be broken), and finally the face shell 111 is ejected out by an ejection mechanism (a top plate and an ejector rod component) in the die to smoothly leave the die core 1.
Wherein, 1 top of mould benevolence is equipped with a plurality of thimble holes, the roof is located the lower mould frame 6 below, the ejector pin passes lower mould frame 6 and erects in mould benevolence 1, the lower extreme and the roof of ejector pin are connected, promote the roof upward movement through the hydro-cylinder, the roof promotes the ejector pin upwards ejecting from the thimble hole, because the laminating of face shell 111 upper side board 112 is at 1 top of mould benevolence, consequently, the ejector pin that comes out from the thimble hole can jack up face shell 111, make face shell 111 upper side board 112 and the separation of 1 top of mould benevolence, finally realize the drawing of patterns of face shell 111.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
