Description
Technical field
The mold-opening structure of injection mold, more particularly to a kind of molar be the utility model is related to away from the automatic of screw injection product
Die-sinking die structure.
Background technology
For denticle away from screw injection product can use the spiral shell of mode product-stripping mechanism that gear drive, synchronous thread rotate
Line is buckled to, but for molar away from screw injection product, gear often rotates one week, and screw thread of the molar away from screw injection product falls
Button die sinking may only have the angle of a very little, therefore have no idea to realize that gear drive rotates synchronously Leave out thread back-off.
But in reality produces, some special products need molar away from functional requirement is completed again, due to not closing
Suitable mould structure completes the die sinking of this product, is only split using product, the mode then connected obtains product, greatly
The big cost for improving product development.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of automatic die sinking of molar away from screw injection product
Mould structure, is capable of the molar of one-pass molding acquisition entirety away from screw injection product, so as to improve the total quality of product, greatly
The big production cost for reducing enterprise.
The utility model is achieved through the following technical solutions：
A kind of automatic die sinking mould structure of molar away from screw injection product, it is characterised in that：
Sliding block fuse includes fuse and the outer fuse of sliding block in the sliding block of coaxial inside and outside fixed configuration, the axial direction of fuse in sliding block
Inner cavity is the outer mold surface of lumen type, and the molar is molded in sliding block in the axial bore of fuse away from screw injection product；
Outside sliding block in fuse outer rim, spiral helicine guide runner is opened up around axial, the spiral tooth of guide runner away from molar away from
The spiral tooth of screw injection product is away from identical；
Corresponding guide runner, sets the sliding block fuse slider guide of position fixation, sliding block fuse slide guide outside sliding block on the outside of fuse
Block one end is stretched into guide runner, and end shape matches with guide runner vallecular cavity shape, sliding when fuse is axially translated outside sliding block
Block fuse slider guide can limit the outer fuse of sliding block at the same time around axial-rotation；
The rotational installation of sliding block fuse one end can turn under external force driving on take-up housing relative to take-up housing around axial
It is dynamic；The take-up housing driven by inclined guide pillar can be moved along sliding block fuse axial reciprocating；
During die sinking, inclined guide pillar driving take-up housing band movable slider fuse along sliding block fuse axial translation, due to sliding block fuse outside
Have on cylindrical surface tooth identical with product screw thread back-off away from guide runner, fixed with position slider guide coordinates guide runner again,
Therefore, for sliding block fuse during translation, limitation of the sliding block fuse slider guide to guide runner forces sliding block fuse in translation
At the same time around axial-rotation, and this rotating tooth away from spiral tooth of the molar away from screw injection product away from identical so that sliding
Block fuse and molar realize that Leave out thread rotates die sinking away from being relatively rotated between screw injection product.
Further, described sliding block fuse one end is rotatablely installed on take-up housing by end face bearing, uses end face bearing
Sliding block fuse can be greatly reduced and rotate the frictional force produced, to achieve the purpose that to reduce opening and closing mould resistance.
Further, the end face number of bearings is be spaced configuration in take-up housing opposite sides 2；Along cunning in take-up housing
One contiguous block for carrying step surface of fuse axial direction arranged coaxial, the step surface of contiguous block are located in take-up housing in block, are close to platform
Terrace and take-up housing side the overcoat second end face bearing on contiguous block small end, pass through second end face between step surface and take-up housing
Bearing is rotatablely connected；Contiguous block small end stretches out take-up housing, is tightly placed in sliding block in fuse, is close in take-up housing opposite side and sliding block
Fuse is set with first end face bearing on the external part of contiguous block, passes through first end face bearing between fuse in take-up housing and sliding block
Rotation connection.Two rolling bearings are rotatablely connected take-up housing and sliding block fuse from the opposite sides of take-up housing, no matter opening and closing mould
When, sliding block fuse is drawn by take-up housing, thrust, ensure stress between the two fully, reliable transmission.
Further, the dorsal part of the outer fuse of sliding block is equipped with template, is close to outer rim allocation position on front side of the outer fuse of sliding block and fixes
Sliding block fuse briquetting, sliding block fuse is limited in the gap between sliding block fuse briquetting and template, limitation sliding block fuse is only
It can be axially moveable or rotate, circular runout of the anti-limited slip block fuse in opening and closing mould.
Further, the sliding block fuse briquetting is that each pair is slided along the multipair of the axial configuration of interval in pairs of fuse outside sliding block
Block fuse briquetting fuse outside sliding block is axially and symmetrically disposed.From both sides to outside sliding block fuse carry out it is spacing, more point symmetries by
Power, it is spacing more reliable.
Further, sliding block fuse slide guide number of blocks can be one or more, but if only one, lead
Extruding between sliding slot and slider guide can produce radial load, be easy to cause the stuck of guide runner and slider guide, it is preferred, therefore, that
The sliding block fuse briquetting is that each pair sliding block fuse briquetting is perpendicular to cunning along the multipair of the axial configuration of interval in pairs of fuse outside sliding block
The outer fuse axially symmetric disposition of block, ensures sliding block fuse stability under loading.
Further, the first sliding block fuse slider guide and the second sliding block fuse slider guide are respectively perpendicular to the outer core of sliding block
Son axially symmetric disposition, two axially symmetric arrangements of slider guide, cancel each other radial load, and stress is more stable.
The beneficial effects of the utility model are：
1st, this structure solves the problems, such as that molar realizes injection production away from plastic product well, and one-pass molding obtains overall
Product, improves the total quality of product, greatly reduces the production cost of enterprise；
2nd, other driving structure need not be configured, by the spacing rotating stripping demoulding for forcing sliding block fuse, easy in complexity
It is arranged in mould structure；
3rd, the symmetrical stress of sliding block fuse, is unlikely to deform, and spacing by sliding block fuse briquetting, and movement is reliable；
4th, it is simple in structure effective, beneficial to the transformation to existing mold.
