Description
Technical field
The utility model relates to the oblique chute side core-pulling mechanism of a kind of injection mold spacing drag hook, belongs to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, as plastic garbage bin etc., the bottom of dustbin is shaped on footing, constitutes back-off between footing and the staving, and product can not directly be deviate from when the demoulding.Prior art adopts the oil cylinder side core-pulling mechanism, and the shortcoming of its existence is: loose core of oil cylinder efficient is low, and the oil cylinder piston bar needs action back and forth when loosing core, and required time is long at interval, influences mould open/close mould speed, and production efficiency is low.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, the oblique chute side core-pulling of a kind of employing mode to be provided, utilize mould open/close mould power, loose core synchronously with the mould open/close mould, the oblique chute side core-pulling mechanism of injection mold spacing drag hook of enhancing productivity.
The technical scheme of the oblique chute side core-pulling mechanism of the utility model injection mold spacing drag hook is: comprise compound plate and following compound plate, last compound plate connects solid plate down, on the following compound plate moving platen is installed, be shaped on core on the moving platen, template in installing on the moving platen, it is framed on the middle template die cavity to be set, core passes middle template, the moulding plastics dustbin is arranged between core and die cavity are framed, the bottom of dustbin is shaped on footing, constitute back-off between footing and the staving, valve is installed in core, the gas outlet of valve is communicated with dustbin, the air inlet of valve is communicated with gas circuit, it is characterized in that the moving angled-lift splits that is provided with of described swaging die middle slide of frame, one side of angled-lift splits contacts with back-off, described solid plate connects oblique guide block down, tiltedly a side of guide block is shaped on oblique chute, and the opposite side of angled-lift splits connects oblique chute, on the framed sidewall of die cavity block tongue is installed, on one sidewall of moving platen drag hook is installed, on one sidewall of solid plate depression bar is installed, depression bar and drag hook match with block tongue respectively, are shaped on stopper slot in the framed side of die cavity, connect controlled interval pull rod in the opposite side of solid plate, controlled interval pull rod matches with stopper slot.
The oblique chute side core-pulling mechanism of injection mold spacing drag hook of the present utility model, during the demoulding, at first drive moving platen and solid plate die sinking by injection machine power, because the effect of block tongue and drag hook, it is framed together to lower open die that the dynamic model strip die cavity, the framed drive angled-lift splits of die cavity along oblique chute outwards to lower slider, disengage with back-off, mould continues die sinking again, depression bar matches with block tongue, with the block tongue compression, block tongue and drag hook disengage, and hold the swaging die frame under the effect of controlled interval pull rod, continue die sinking again, core on the moving platen is inserted and is being with the dustbin and the framed demoulding of die cavity, and by valve dustbin being inserted from core at last blows out, and dustbin demoulding from mould is finished.This programme adopts oblique chute side core-pulling mode, utilize mould open/close mould power, angled-lift splits and mould open/close mould are loosed core synchronously, utilize cooperating of drag hook and depression bar and block tongue again, under the effect of controlled interval pull rod, product is deviate from from die cavity is framed, mould need not special-purpose ejecting mechanism, simplifies mould structure, and investment reduces cost, saving is loosed core the time, enhances productivity.
Description of drawings
Fig. 1 is the oblique chute side core-pulling mechanism of a utility model injection mold spacing drag hook structural representation.
The specific embodiment
The utility model relates to the oblique chute side core-pulling mechanism of a kind of injection mold spacing drag hook, as shown in Figure 1, comprise compound plate 1 and following compound plate 2, last compound plate connects solid plate 3 down, moving platen 5 is installed on the following compound plate 2, be shaped on core 6 on the moving platen 5, template 7 in installing on the moving platen 5, on the middle template 7 die cavity framed 4 is set, core 6 passes middle template 7, between core 6 and the die cavity framed 4 moulding plastics dustbin 8 is arranged, the bottom of dustbin is shaped on footing 9, constitute back-off 10 between footing and the staving, valve 20 is installed in core 6, the gas outlet of valve 20 is communicated with dustbin 8, the air inlet of valve 20 is communicated with gas circuit, it is characterized in that sliding in the described die cavity framed 4 angled-lift splits 11 is set, one side of angled-lift splits 11 contacts with back-off 10, described solid plate connects oblique guide block 12 for 3 times, tiltedly a side of guide block 12 is shaped on oblique chute 13, the opposite side of angled-lift splits 11 connects oblique chute 13, block tongue 15 is installed on a sidewall of die cavity framed 4, drag hook 16 is installed on one sidewall of moving platen 5, depression bar 17 is installed on one sidewall of solid plate 3, and depression bar 17 and drag hook 16 match with block tongue 15 respectively, are shaped on stopper slot 18 in the side of die cavity framed 4, connect controlled interval pull rod 19 in the opposite side of solid plate 3, controlled interval pull rod 19 matches with stopper slot 18.During the demoulding, at first drive moving platen and solid plate die sinking by injection machine power, because the effect of block tongue and drag hook, the dynamic model strip die cavity framed 4 together to lower open die, die cavity framed 4 drive angled-lift splitses 11 along oblique chute 13 outwards to lower slider, disengage with back-off, mould continues die sinking, and depression bar matches with block tongue, block tongue 15 has the compression spring, with the block tongue compression, block tongue and drag hook disengage, and hold swaging die frame 4 under the effect of controlled interval pull rod, continue die sinking again, core on the moving platen is inserted and 6 is being with the dustbin and framed 4 demouldings of die cavity, and by valve dustbin being inserted from core at last 6 blows out, and dustbin demoulding from mould is finished.This programme adopts oblique chute side core-pulling mode, utilize mould open/close mould power, angled-lift splits and mould open/close mould are loosed core synchronously, utilize cooperating of drag hook and depression bar and block tongue again, under the effect of controlled interval pull rod, product is deviate from from die cavity is framed, mould need not special-purpose ejecting mechanism, simplifies mould structure, and investment reduces cost, saving is loosed core the time, enhances productivity.
