Description
Technical Field
The utility model relates to an automobile lamp dress escutcheon mould secondary ejection mechanism belongs to the injection mold field.
Background
Adopt injection mold to produce plastic products, for example the dress escutcheon of car light etc. according to product appearance and structural analysis, be equipped with the darker strengthening rib of a plurality of degree of depth on this dress escutcheon, embody in injection mold, the strengthening rib inlays deeply in the core of mould, when ejecting, if adopt conventional thimble directly ejecting, because the strengthening rib degree of depth is dark, is pulled wounded, is drawn badly very easily, leads to the product to scrap, consequently, need design a secondary ejecting structure, avoid haring the strengthening rib.
Disclosure of Invention
The utility model aims at overcoming prior art's shortcoming, providing one kind and utilizing thimble board ejecting power, combining the ejecting structure of distance, it is ejecting to realize the secondary, makes the car light decorative frame mould secondary ejection mechanism that the strengthening rib deviates from smoothly.
The utility model discloses car light dress escutcheon mould secondary ejection mechanism's technical scheme is: including die cavity compound board and core compound board, set up the die cavity frame under the die cavity compound board, set up the die cavity in the die cavity frame and insert, set up the mould foot on the both sides of die core compound board, set up roof and last roof down between the mould foot, set up the core fixed plate on the mould foot, set up the core on the core fixed plate, the core inserts and constitutes the die cavity between the die cavity frame with the die cavity, has injection moulding's car light dress escutcheon in the die cavity, and the system has strengthening rib, its characterized in that on the car light dress escutcheon: the core fixing plate is provided with a reinforcing rib insert, a reinforcing rib ejection block is arranged in the core, the reinforcing rib ejection block and the reinforcing rib insert are spliced, the reinforcing rib is embedded between the reinforcing rib ejection block and the reinforcing rib insert, two secondary ejector rods are respectively connected to two sides of the lower top plate, two outer side walls of the core are respectively provided with an elastic block, the secondary ejector rods are ejected on the bottom surface of the elastic block, the top end part of the elastic block is provided with a fixed-distance inclined surface, fixed-distance pressing rods are respectively arranged on two outer side walls of the core fixing plate, fixed-distance pressing blocks are arranged on the fixed-distance pressing rods, and the fixed-distance pressing blocks are matched with the fixed-distance inclined surfaces.
The utility model discloses an automobile lamp dress escutcheon mould secondary ejection mechanism, when ejecting, drive the core by the injection molding machine power and insert and the separation of die cavity frame die sinking with the die cavity, after the die sinking to the certain distance, the roof up pushes up under the push rod drive of injection molding machine, at this moment, the roof takes secondary ejector pin and goes up the roof simultaneously down, because secondary ejector pin top is on the bottom surface of abaculus, it pushes up to drive the core through the abaculus, the core takes ejecting piece of strengthening rib and car lamp dress escutcheon to push up, the strengthening rib is inserted and is fixed on the core fixed plate motionless, make the strengthening rib deviate from the strengthening rib and insert, after the certain distance of pushing up, under the cooperation on distance briquetting and distance inclined plane, the abaculus shrinkages, break away from with the secondary ejector pin, the ejecting piece of core and strengthening rib resets, and the roof still drives down the roof and continues to push up, it is outside the ejecting mould of car lamp dress escutcheon is moved to drive the thimble by last roof, the drawing of patterns is accomplished. This scheme passes through the ejecting structure of secondary, drives core and the ejecting piece of strengthening rib earlier and pushes up, and the strengthening rib is inserted motionlessly, makes the strengthening rib deviate from easily, can not hinder by the pulling, continues to push up by the thimble again, outside the ejecting mould of car light dress escutcheon, realizes automatic drawing of patterns, and structural design is reasonable, and the action is stable, reliable, and production efficiency is high, and need not to put in addition and push up power, and manufacturing cost saves.

Detailed Description
The utility model relates to an automobile lamp decorative frame mould secondary ejection mechanism, as shown in fig. 1-fig. 3, including die cavity compound plate 1 and core compound plate 2, set up die cavity frame 3 under the die cavity compound plate, set up the die cavity in the die cavity frame and insert 5, set up mould foot 6 on the both sides of core compound plate, set up down roof 7 and last roof 8 between the mould foot, set up core fixed plate 9 on the mould foot, set up core 10 on the core fixed plate, core 10 and die cavity insert 5 and constitute the die cavity between the die cavity frame 3, have injection moulding's car lamp decorative frame 11 in the die cavity, the system has strengthening rib 12 on the car lamp decorative frame, installation strengthening rib insert 15 on the core fixed plate 9, installation strengthening rib ejecting block 16 in the core 10, strengthening rib ejecting block 16 inserts 15 with the strengthening rib and amalgamates mutually, and strengthening rib ejecting block 16 and strengthening rib insert between 15, respectively connect secondary ejector pin 17 in the both sides of roof 7 down, the both sides outer wall of core 10 respectively set up bullet piece 18, secondary ejector pin 17 pushes up on bullet piece bottom surface 18, the top surface tip of the top surface of the top of bullet piece sets up the inclined plane 21, the distance installation pressure bar 19 both sides of distance, distance press block 20, distance press bar 20 press from the both sides of distance, press and 20 press the distance and match. When the mold is opened to a certain distance, a push rod of the injection molding machine drives the lower top plate 7 to push upwards, at the moment, the lower top plate 7 drives the secondary ejector rod 17 and the upper top plate 8 to push upwards at the same time, as the secondary ejector rod 17 pushes against the bottom surface of the elastic block 18, the elastic block 18 drives the mold core 10 to push upwards, the mold core 10 drives the reinforcing rib ejector block 16 and the automobile lamp decoration frame 11 to push upwards, the reinforcing rib insert 15 is fixed on the mold core fixing plate 9 and is fixed, so that the reinforcing rib 12 is separated from the reinforcing rib insert 15, after the mold core 10 pushes upwards for a certain distance, under the matching of the fixed-distance press block 20 and the fixed-distance inclined plane 21, the elastic block 18 retracts inwards to separate from the secondary ejector rod 17, the mold core 10 and the reinforcing rib ejector block 16 reset, the lower top plate 7 also drives the upper top plate 8 to push upwards continuously, the upper top plate 8 drives the ejector pin 22 to push the automobile lamp decoration frame 11 out of the mold, and demolding is completed. This scheme passes through the ejecting structure of secondary, drives core and the ejecting piece of strengthening rib earlier and pushes up, and the strengthening rib is inserted motionlessly, makes the strengthening rib deviate from easily, can not the strain, continues to push up by the thimble again, outside the ejecting mould of car light dress escutcheon, realizes automatic drawing of patterns, and structural design is reasonable, and the action is stable, reliable, and production efficiency is high, and need not to put in addition and push up power, and manufacturing cost province.
