Abstract
The utility model discloses an ultralong pitched roof guide structure, which comprises a pitched roof, a mold core and guide strips, wherein the pitched roof adopts a concave-convex structure to be connected in the guide strips in a sliding way, the guide strips are formed by splicing more than three sections of guide blocks, one side of the mold core is provided with a mounting groove corresponding to each guide block, the depth of the mounting grooves is gradually deepened, and one end of the pitched roof, which is provided with barb forming characteristics, is positioned in the narrowest mounting groove; the groove bottom of the mounting groove is parallel to the side face of the mold core, and the guide block is fixed in the corresponding mounting groove by bolts. The utility model discloses assemble the sectional type gib block in the core, adopt slow filament to cut out the spout that is used for the oblique top direction in shorter guide block, then adopt the mode of polishing or increasing the gasket to the guide block in the die assembly link to go the trim spout, not only reduced the processing degree of difficulty of spout, still reduced the processing cost of mould.
Description
Technical Field
The utility model belongs to the technical field of injection mold, involve the oblique top that is used for shaping the inside barb of moulding, especially overlength oblique top.
Background
The die lifter is also called a lifter pin and a lifter, is a mechanism for forming barbs in products in die design, and is suitable for simpler barb conditions. The one end design that the oblique top is located the die cavity has the characteristic of shaping barb, and the other end adopts cylindrical member such as round pin axle to install in the oblique footstock in the thimble board, if the die cavity degree of depth is super deep, the core is relative elongated, for the operation stability of guaranteeing the oblique top, then can increase the spout that is used for oblique top direction in the core. The spout that sets up in the core is the slope form, and unable clamping in slow wire cutting lathe if adopt the machining finish milling spout, firstly will set up corresponding supplementary tool, with the tank bottom lifting of spout to horizontal plane, secondly the cost of finish milling processing is higher, has increased the processing cost of mould.
SUMMERY OF THE UTILITY MODEL
The utility model provides a overlength pushes up guide structure to one side, its one of which purpose reduces the processing degree of difficulty of spout, and its two purposes are, reduce the processing cost of mould.
In order to achieve the above purpose, the utility model provides a technical scheme as follows:
the overlong inclined top guide structure comprises an inclined top, a mold core and guide strips, wherein the inclined top is in sliding connection in the guide strips by adopting a concave-convex structure, the guide strips are formed by splicing more than three guide blocks, one side of the mold core is provided with a mounting groove corresponding to each guide block, the depth of the mounting grooves is gradually deepened, and one end of the inclined top, which is provided with a barb forming characteristic, is positioned in the narrowest mounting groove; the groove bottom of the mounting groove is parallel to the side face of the mold core, and the guide block is fixed in the corresponding mounting groove by bolts.
Compared with the prior art, the beneficial effects of the utility model are that: the sectional guide strips are assembled in the mold core, the slow wire is adopted to cut out the sliding groove for oblique jacking guide in the shorter guide block, then the sliding groove is leveled by polishing or adding a gasket to the guide block in the mold assembly link, the processing difficulty of the sliding groove is reduced, and the processing cost of the mold is also reduced.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.
FIG. 1 is a structural view of a guide bar disclosed in the embodiment;
FIG. 2 is a block diagram of a core disclosed in an embodiment;
FIG. 3 is a structural view of a pitched roof disclosed in the embodiments;
fig. 4 is an installation structure view of the lifter and the guide bar disclosed in the embodiment.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Examples
The overlength pushes up guide structure to one side includes oblique top, core and gib block.
Referring to fig. 1, the guide bar is formed by splicing a first guide block 10, a second guide block 20 and a third guide block 30. Referring to fig. 2, one side of the mold core 40 is provided with a first mounting groove 41, a second mounting groove 42 and a third mounting groove 43 which are sequentially deepened from top to bottom, the bottom of the groove is parallel to the side surface 45 of the mold core, the first guide block 10 is fixed in the first mounting groove 41 by bolts, the second guide block 20 is fixed in the second mounting groove 42 by bolts, and the third guide block 30 is fixed in the third mounting groove 43 by bolts. T-shaped grooves 50 are formed in all the three guide blocks, T-shaped blocks 61 are arranged on one sides of the inclined tops 60 corresponding to the guide strips, and the inclined tops and the guide blocks are in sliding connection through the concave-convex structures (see figure 4). T type groove makes up into the spout that is used for the oblique top to lead in the three guide block, and T type groove adopts the slow silk to cut one and repaiies two, removes the trim spout to the guide block adoption mode of polishing or increasing the gasket in the mould assembly link, so only need in the core machine tooling three mounting groove can, the machining precision requirement of these three mounting grooves is far less than the required precision of spout moreover, and the tank bottom is also parallel with the core side, so need not to set up auxiliary tool in addition, and the machining cost also reduces by a wide margin.
The top end of the T-shaped groove of the first mounting groove 41 is a closed end, and a through hole 411 matched with the width of the inclined top is formed in the closed end. The top of the inclined top is provided with a barb forming feature 62, the end is located in the T-shaped groove of the first mounting groove 41, a distance is reserved between the top end of the T-shaped block and the end of the T-shaped block, after the inclined top is ejected by the ejector plate, the top end of the inclined top penetrates through the through hole 411 for a certain distance and is limited by the T-shaped groove, and therefore the T-shaped groove at the highest position is set to be a closed end, and the stroke of the inclined top can be limited.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
