Description
Technical field
The utility model relates to plastic mold device fields, refer specifically to a kind of injection mold of line position anti-back.
Background technique
With the development of plastics industry, the moulding of plastic product increasingly diversification and complication, some structure needs make
Core pulling is assisted with driving equipments such as oil cylinders, oil cylinder has the risk of rollback under higher injection pressure, may cause product part
Defect, it is therefore desirable to which a set of retreating prevention mechanism, which is arranged, prevents line position from retreating.But make for being arranged at more than 100 mm depths of rear mold
With the diagonal position of driving equipment auxiliary core pulling, if the product area being affected by it is little, the considerations of in terms of die cost, one
As tend to be not provided with retreating prevention mechanism, and select the biggish driving equipment of thrust because driving equipment itself just have it is certain
Anti-back ability.But in view of conventional driving equipment, for example the natural aging of components and hydraulic system push away oil cylinder in oil cylinder
The influence of power, it is insecure that line position retrogressing is only prevented by driving equipment itself, it is therefore necessary to for being set to rear mold
The line position exploitation of shallower position uses the injection mold of lower cost anti-back scheme.
Summary of the invention
The main purpose of the utility model be for the shallower position line position of rear mold anti-back provide it is a kind of using lower cost
The injection mold of the line position anti-back of anti-back scheme.
To achieve the above object, the utility model provides a kind of injection mold of line position anti-back, including preceding mould, rear mold, tiltedly
Line position and set on rear mold bottom line position sliding block, shovel base and driving device, diagonal position be disposed through in rear mold, diagonal position
Top is forming ends, and the bottom end of diagonal position is driving end, is fixedly connected at the top of driving end and line position sliding block.Line position slider bottom
Equipped with line position inclined-plane, the first end for shoveling base is equipped with the pushing tow inclined-plane cooperated with line position inclined-plane, shovels the second end and driving device of base
The connection of driving end, shovel base laterally moves, and preceding mould moves longitudinally, and is vertically equipped with anti-back before being characterized in that on mould
Inserted link, shovel base top are equipped with limit jack, and anti-back inserted link passes through rear mold and is inserted into limit jack.
Shovel base is consolidated as it can be seen that can be realized by the anti-back inserted link for being arranged through rear mold on preceding mould by above scheme
It is fixed, so that line position caused by preventing because of driving device thrust deficiency retreats.It is inserted by the way that anti-back plunger end and limit is rationally arranged
The length and shape in hole are it is ensured that the process that anti-back inserted link extraction limit jack and shovel base retreat demoulding can synchronize progress
And it does not interfere with each other.It prevents from line position from retreating by the way that anti-back structure is arranged in rear mold just to need in view of various types of in rear mold
The interference of line position and oblique top and thimble, therefore the arrangement space of this kind of anti-back structure is smaller, structure is also complex.Preceding mould
Structure is relatively easy, is also easier to setting anti-back structure, and above scheme is only direct across rear mold by the way that one is arranged on preceding mould
The rod-like structure for acting on shovel base just can effectively prevent line position retrogressing.
One Preferable scheme is that, the bottom end of anti-back inserted link is in rounding mesa-shaped, and limit jack is inverted round stage hole.
Further embodiment is that caulking groove is equipped at the top of shovel base, and wear-resisting abaculus is fixed in caulking groove, and limit jack is set to resistance to
It grinds on abaculus.
The part of shovel base and the cooperation of anti-back inserted link needs to have stronger wear-resisting property, in shovel base differential trench open and by this portion
Divide and is substituted for the durability that more wear resistant material helps to improve part entirety.
Further scheme is that wear-resisting abaculus is located at the top on shovel base with pushing tow inclined-plane opposite side.
This set form helps to reduce the length dimension of shovel base, and optimization shovel based structures, in addition caulking groove may also be arranged to
Nick shaped is more convenient for processing.
Further scheme is that wear-resisting abaculus bottom is equipped with retention bead, and caulking groove part invagination is formed and retention bead
The limiting slot of cooperation.
Wear-resisting abaculus and caulking groove can be made tight by the way that retention bead and limiting slot are arranged on wear-resisting abaculus and caulking groove respectively
Close occlusion, accordingly even when being not connected firmly can also guarantee on the traffic direction of shovel base not between the two by the cooperation on own form
It relatively moves.
Further embodiment is, line position sliding block is equipped with guide pad on line position inclined-plane, shovel base be equipped on pushing tow inclined-plane with
The guide chute of guide pad cooperation.
Line position sliding block can be reinforced and shovel the cooperation of base by introducing guide pad and guide chute, preferably control line position sliding block
Sliding, while preventing line position sliding block from slipping from shovel base.
One Preferable scheme is that, guide pad is L-type block, and the section of guide chute is L-shaped.
Further scheme is that shovel basal surface is equipped with guiding rib along its length, and rear mold is equipped with to be cooperated with guiding rib
Guiding card slot.
The sliding of rear mold can be introduced for shovel base phase by the way that guiding rib is respectively set on shovel base and rear mold and is oriented to card slot
Limit mechanism, and guarantee anti-back inserted link and limit the accurate contraposition between jack.
