Description
Technical field
This utility model relates to a kind of injection mold with front mould tunnel loose core mechanism.
Background technology
Injection mold is the instrument producing plasthetics, and the material melted that is heated is injected die cavity by high pressure by it, after cooled solidification, obtains formed products.Owing to the structure of current plastic becomes increasingly complex, producing and usually need to use front mould tunnel loose core mechanism in the mould of these plastics, this front mould tunnel loose core mechanism is the mechanism that a kind of moulding section making the obstruction moulding demoulding departs from moulding before die sinking action completes.
But, front mould tunnel loose core mechanism in existing most injection mold comes with some shortcomings part in structure design, these front moulds tunnel loose cores mechanism makes mold actions have some setbacks, positioning precision is poor, the mould production cycle is long, daily maintenance cost is high so that the goods that mould is produced are without the market competitiveness.
Patent publication No. CN204749163U discloses a kind of injection mold with front mould tunnel loose core mechanism；This structure can effectively solve the problems referred to above, but the body of loosing core in this structure can not preferably control the distance of outer shifting well when displacement to the right, when the distance of outer shifting is excessive, the return stroke of body of loosing core is bigger, more lose time, body of simultaneously loosing core does not has the function of outwards ejection, therefore needs manually to extract out after pushing, more bothers.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of injection mold with front mould tunnel loose core mechanism, this device is by regulating the engagement height of guide plate, can regulate body of loosing core probes into the degree of depth, can be controlled to loose core the distance of this external shifting by the upper shifting distance of movable block, shorten return stroke, this device can realize loosing core by spring the automatic spring of body, simple to operation.
For solving the problems referred to above, this utility model adopts the following technical scheme that
nullA kind of injection mold with front mould tunnel loose core mechanism，Including top panel and lower panel，The lower section of described top panel is provided with die block，The top of described lower panel is provided with solid punch，A die cavity is formed between described die block and described solid punch，It is provided with die in described die cavity，The slide block coordinating described die it is provided with at the leftward position of described die cavity，The passage of a rectangle is formed between described die block and described solid punch，The right side of described die has the through hole being coaxially disposed with described passage，It is combined with, in described through hole, body of loosing core，The right-hand member of described body of loosing core has pushing block，Interference fits between described pushing block and described passage，It is combined with back-moving spring in described passage，Described back-moving spring is loosed core on body described in being set in，The right-hand member of described die block is combined with hydraulic cylinder，The outfan of described hydraulic cylinder is combined with movable block，The right side of described pushing block has a guiding surface，Described movable block has the first inclined-plane coordinating described guiding surface，The right-hand member of described solid punch is combined with adjustable plate，It is combined with screw between described adjustable plate and described solid punch，Described adjustable plate is combined with guide plate away from that one end of described solid punch，Described guide plate is L-shaped，The right flank of described movable block offsets with described guide plate，The right side of described slide block has the locating slot of a taper，The left end of described body of loosing core has the built-in end coordinating described locating slot，Described built-in end has the tapering communicated with described locating slot.
