Abstract
The invention provides a pitched roof structure of a mold for processing a reverse L-shaped piece, which has the advantages of convenient ejection, no pull damage to workpieces, and high ejection qualification rate. The structure is characterized by comprising an upper mold, a lower mold and a pitched roof, wherein a stop dog is arranged on the lower mold; the stop dog is attached to the slot bottom surface of a vertical slot of the pitched roof; an ejection pin is arranged on the pitched roof; the ejection pin passes through a cover plate; and the cover plate is connected with the pitched roof.
Description
Technical field
The present invention relates to the parts of mould of plastics, be specially the ramp-roof structure of inverted L shape spare die for processing.
Background technology
Inverted L shape spare is characterised in that it is elongated, and it comprises upper die and lower die, ramp-roof structure processed mould, and die sinking is to eject workpiece by oblique top.When oblique top covers the area of product when big, product is bonded on the oblique top easily, easy like this pulling.
Summary of the invention
At the problems referred to above, the invention provides the ramp-roof structure of inverted L shape spare die for processing, it ejects conveniently, can not pull workpiece, and it is higher to eject qualification rate.
Its technical scheme is such: it comprises upper die and lower die, oblique top, on the described counterdie block is installed, the groove bottom of the vertical slots of block and oblique top is fitted, and it is characterized in that: on the described oblique top thimble is installed, described thimble passes cover plate, and described cover plate is connected with described oblique top.
It is further characterized in that: described oblique top is provided with the deep gouge hole, the inwall in described deep gouge hole is provided with the round platform wall, described thimble passes described deep gouge hole, the end face of its outer end and oblique top is concordant, its inner side end stretches out from described oblique top, the outer cover of described thimble is equipped with spring, and an end of described spring press-fits in the round platform internal face in described deep gouge hole, the other end nut press mounting of described spring; The bottom land of described oblique top is parallel with the faying face of described counterdie with described oblique top, and the outer transverse plane of described block is a vertical plane; During matched moulds, the decrement of the ultimate range H1=spring between the contact point of described block the top and described oblique top and the faying face of described oblique top and described counterdie; The stroke of oblique top was S1 when thimble kept motionless with respect to finished product, S2 is the range of oblique top, S1+10mm=S2, and the distance during matched moulds between the faying face of described bottom land and described oblique top and described counterdie is T, the longest distance that described thimble stretches out described oblique top is T1, T=T1+0.2mm;
The present invention adopts after the said structure, and during die sinking, oblique top is moved along oblique line directions, and product is bonded on the oblique top, and thimble withstands on the block, and block is motionless, and the relative oblique line of thimble has relative motion, and workpiece is thrown off, and is convenient and swift, and workpiece is difficult for being pulled.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
See Fig. 1, the present invention includes patrix 1, counterdie 2, oblique top 4, block 3 is installed on the counterdie 2, block 3 is fitted with the groove bottom of the vertical slots of oblique top 4, and thimble 6 is installed on the oblique top 4, and thimble 6 passes cover plate 5, and cover plate 5 is connected with oblique top 4.Oblique top 4 is provided with the deep gouge hole, the inwall in deep gouge hole is provided with the round platform wall, thimble 6 passes the deep gouge hole, its outer end is concordant with the end face of oblique top 4, its inner side end stretches out from oblique top 4, the outer cover of thimble 6 is equipped with spring 7, and an end of spring 7 press-fits the round platform internal face in the deep gouge hole, and the other end of spring 7 press-fits with nut 8; The bottom land of oblique top 4 is parallel with the faying face of counterdie 2 with oblique top 4, and the outer transverse plane of block 3 is a vertical plane; During matched moulds, the decrement of the ultimate range H1=spring between the contact point of block 3 the tops and oblique top 4 and the faying face of oblique top and counterdie; The stroke of oblique top 4 was S1 when thimble 6 kept motionless with respect to finished product, S2 is the range of oblique top 4, S1+10mm=S2, and the distance during matched moulds between the faying face of bottom land and oblique top 4 and counterdie 2 is T, the longest distance that thimble 6 stretches out oblique top 4 is T1, T=T1+0.2mm.
