Abstract
A mechanical injection mold oblique-pulling reverse fastener demolding mechanism comprises an upper mold plate and a lower mold plate. The upper mold plate is connected with a fixed mold plate by the aid of a runner plate; a fixed mold insert is mounted in the fixed mold plate; a support block is mounted on the lower mold plate; an ejector plate is arranged in the support block; an ejector rod is connected onto the ejector plate; a movable mold plate is mounted on the support block; a movable mold insert is mounted in the movable mold plate; a formed plastic product is arranged between the movable mold insert and the fixed mold insert; and a reverse fastener is manufactured on the back of the product. The mechanical injection mold oblique-pulling reverse fastener demolding mechanism is characterized in that a slider is slidably arranged on one side of the movable mold plate, a tapered wedge is connected below one side of the fixed mold plate, an outer inclined sliding groove is manufactured on the tapered wedge and connected with the outer side of the slider, an inner inclined sliding groove is manufactured on the inner side of the slider, an inclined rod is connected onto the inner inclined sliding groove, and the head of the inclined rod is matched with the reverse fastener. The mechanism in the scheme adopts an oblique-pulling mode for demolding the reverse fastener, and is compact in structure, stable and reliable in action, easy in processing and cost-saving.
Description
Technical field
The utility model relates to a kind of injection mold mechanical type tiltedly to be taken out and takes off back-off mechanism, belongs to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product,, generally all be shaped on back-off on the product, therefore, when product ejects, need carry out the demoulding to back-off earlier as automobile interior decoration spare etc.The mode that prior art is taken off back-off generally adopts oblique top mechanism, and its advantage is: slanted kicking block ejects product outside the mould again when taking off back-off, shortens the product stripping time, enhances productivity.But automobile interior decoration spare mostly is little product, adopts oblique top mechanism, and slanted kicking block does not have sliding distance on product, can't use.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of employing wedge to drive slide block, and slide block drives that brace is oblique looses core, compact conformation, and action is stable, the injection mold mechanical type is tiltedly taken out and taken off back-off mechanism reliably.
The utility model injection mold mechanical type is tiltedly taken out the technical scheme of taking off back-off mechanism: comprise upper mould plate and lower bolster, cope match-plate pattern connects solid plate through runner plate, fixed die insert is installed in the solid plate, the mould pin is installed on the lower bolster, in the mould pin top board is set, connect push rod on the top board, on the mould pin moving platen is installed, moving die insert is installed in the moving platen, the plastic product that moulding is arranged between moving die insert and the fixed die insert, the back side of product is shaped on back-off, it is characterized in that described moving platen one side slip is provided with slide block, under a side of solid plate, connect wedge, be shaped on outer oblique chute on the wedge, outer tiltedly chute connects the outside of slide block, oblique chute in the inboard of slide block is shaped on, bracing diagonal on the interior tiltedly chute, the head of brace matches with back-off.
Injection mold mechanical type of the present utility model is tiltedly taken out and is taken off back-off mechanism, during work, at first drive moving platen and moving die insert and solid plate and fixed die insert die sinking by injection machine power, moving platen drives slide block and moves downward, because the outside of slide block is connected in the outer oblique chute of solid plate wedge, when therefore moving downward when sliding, outwards slide along outer tiltedly chute, slide block drives brace simultaneously and outwards looses core, and owing to oblique chute in the inboard of slide block is shaped on, brace is connected in the interior tiltedly chute, therefore, when brace is outwards loosed core along interior oblique chute to lower slider, the head of brace and product back-off are disengaged, back-off demoulding success.This programme adopts the mode of tiltedly taking out that back-off is carried out the demoulding, compact conformation, and action is stable, reliable, handling ease, cost is economized.
Injection mold mechanical type of the present utility model is tiltedly taken out and is taken off back-off mechanism, and described slider bottom is provided with wearing plate, reduces slider wear.
Description of drawings
Fig. 1 is that the utility model injection mold mechanical type is tiltedly taken out and taken off back-off mechanism structure schematic diagram;
Fig. 2 is that of the present utility model tiltedly taking out taken off back-off mechanism schematic perspective view.
The specific embodiment
The utility model relates to a kind of injection mold mechanical type and tiltedly takes out and take off back-off mechanism, as Fig. 1, shown in Figure 2, comprise upper mould plate 1 and lower bolster 2, cope match-plate pattern 1 connects solid plate 4 through runner plate 3, fixed die insert 5 is installed in the solid plate, mould pin 6 is installed on the lower bolster, top board 7 is set in the mould pin, connect push rod 8 on the top board, moving platen 9 is installed on the mould pin, moving die insert 11 is installed in the moving platen, is constituted the die cavity of moulding plastics product between moving die insert and the fixed die insert, plastic product 12 is arranged in the die cavity, the back side of plastic product is shaped on back-off 13, it is characterized in that described moving platen 9 one sides slip is provided with slide block 15, under a side of solid plate 4, connect wedge 16, be shaped on outer tiltedly chute 17 on the wedge, outer tiltedly chute 17 connects the outside of slide block 15, oblique chute 18 in the inboard of slide block 15 is shaped on, bracing diagonal 19 on the interior oblique chute, the head of brace 19 matches with back-off 13.During work, at first drive moving platen 9 and moving die insert 11 and solid plate 4 and fixed die insert 5 die sinkings by injection machine power, moving platen 9 drives slide block 15 and moves downward, because the outside of slide block 15 is connected in the outer oblique chute 17 of solid plate 4 wedges 16, therefore when slip 15 moves downward, outwards slide along outer tiltedly chute 17, slide block 15 drives brace 19 simultaneously and outwards looses core, and owing to oblique chute 18 in the inboard of slide block 15 is shaped on, brace 19 is connected in the interior tiltedly chute 18, therefore, when brace 19 is outwards loosed core along interior oblique chute 18 to lower slider, the head and product 12 back-offs 13 of brace 19 are disengaged, and back-off demoulding success drives push rod 8 by top board 7 then plastic product 12 is ejected outside the mould.This programme adopts the mode of tiltedly taking out that back-off is carried out the demoulding, compact conformation, and action is stable, reliable, handling ease, cost is economized.Described slide block 15 bottoms are provided with wearing plate 20, reduce slider wear.
