Description
Technical field
The utility model relates to the oblique side core-pulling mechanism of a kind of desk lamp.
Background technology
In mould of plastics product, there is hole and boss in the sidewall of some product, and after formed product, these positions hinder the depanning of product, and product has no idea to eject, and this phenomenon is called back-off in Design of Dies.Back-off is a kind of common structure in plastic, and its effect is to utilize the strain of plastic material to complete and being connected of other parts.In rod-type desk lamp, adopt back-off structure to be connected with other parts, but demoulding difficulty is large.
In addition, in the structure of traditional mould, generally adopt mould right-hand side work point type, or all after plastic piece shaping, carry out second operation work and process.Cause like this efficiency of production to be had a greatly reduced quality, and affected the outward appearance of product; Also have comparatively complicated oblique core drawing mechanisms such as adopting rack-and-pinion to carry out the demoulding, these ways are all unfavorable for reducing the cost that mould is manufactured.
Utility model content
In order to solve the deficiencies in the prior art, make the rod-type desk lamp success demoulding, the utility model provides a kind of desk lamp oblique side core-pulling mechanism.Tiltedly the feature of side core-pulling mechanism is to utilize the thrust of ejecting mechanism to drive slanted pushing rod oblique movement, when plastic is pushed out the demoulding, by oblique side slide, is completed undercut and is loosed core action.The demoulding is simple, has improved production efficiency.
The utility model adopts following technical scheme:
The oblique side core-pulling mechanism of a kind of desk lamp, comprise dead man, oblique side slide and oblique side slide mold insert, the oblique side core-pulling mechanism of desk lamp is arranged in table lamp clamp box cover die, table lamp clamp box cover die comprises A plate, B plate, cover half mold insert and dynamic model mold insert, on A plate, have desk lamp die cavity, cover half mold insert is fixed on A plate, and A plate is connected with cover half fixed head by spring, spring bottom is connected with limited screw, and A plate and cover half fixed head contact-making surface form the first die joint; Dynamic model mold insert is fixed on B plate, and B plate has been bolted dynamic mould fixing plate, and A plate and B plate close button, and cover half mold insert and dynamic model mold insert contact-making surface form the second die joint; Dead man is fixed on cover half fixed head, and dead man is connected by T-shaped groove with oblique side slide, and tiltedly side slide connects oblique side slide mold insert.
Preferably, between described oblique side slide mold insert and desk lamp die cavity, leave gap, gap width is 0.5mm-2mm.
Preferably, described table lamp clamp box cover die also comprises sprue bush, and the bottom of sprue bush is communicated with desk lamp die cavity, and the bottom of sprue bush is also provided with sprue puller.
Preferably, described dynamic model mold insert is connected with thimble.
Useful technique effect of the present utility model:
Tiltedly between side slide mold insert and desk lamp die cavity, leave gap, gap width is 0.5mm-2mm, and during the demoulding, the product of injection moulding is easily separated with mould.
The bottom of sprue bush is also provided with sprue puller, is used for pulling out the plastic column solidifying in the interior melt dividing of mould of injection mo(u)lding.
Dynamic model mold insert is connected with thimble, conveniently the product of injection moulding is separated from mould.
The oblique side core-pulling mechanism of desk lamp of the present utility model utilizes the thrust of ejecting mechanism to drive slanted pushing rod oblique movement, when plastic is pushed out the demoulding, by oblique side slide, is completed undercut and is loosed core action.The demoulding is simple, has improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the oblique side core-pulling mechanism structural representation of desk lamp.
Fig. 2 is the schematic rear view of Fig. 1.
The specific embodiment
1 to 2 pair of specific embodiment of the present utility model is described further by reference to the accompanying drawings:
The oblique side core-pulling mechanism of a kind of desk lamp, comprise dead man 3, oblique side slide 5 and oblique side slide mold insert 6, the oblique side core-pulling mechanism of desk lamp is arranged in table lamp clamp box cover die, table lamp clamp box cover die comprises A plate 4, B plate 10, cover half mold insert 8 and dynamic model mold insert 9, on A plate 4, have desk lamp die cavity 7, cover half mold insert 8 is fixed on A plate 4, and A plate 4 is connected with cover half fixed head 2 by spring 14, and A plate 4 forms the first die joint 20 with cover half fixed head 2 contact-making surfaces; Spring 14 bottoms are connected with limited screw 15, and dynamic model mold insert 9 is fixed on B plate 10, and B plate 10 has been bolted dynamic mould fixing plate 13.A plate 4 closes button with B plate 10, and cover half mold insert 8 forms the second die joint 30 with dynamic model mold insert 9 contact-making surfaces.Dead man 3 is fixed on cover half fixed head 2, and dead man 3 is connected by T-shaped groove with oblique side slide 5, and tiltedly side slide connects oblique side slide mold insert.Tiltedly side slide 5 is horizontal by 45° angle.Tiltedly between side slide mold insert 6 and desk lamp die cavity 7, leave gap, gap width is 0.5mm-2mm.
The plastics of melting inject sprue bush 1 from the nozzle of injection machine, enter in the desk lamp die cavity 7 of mould inside, after injection mo(u)lding, due between cover half fixed head 2 and A plate 4 under the elastic force effect of spring 14, the first die joint 20 is first opened, because dead man 3 is fixed on cover half fixed head 2, so along with the move distance of the first die joint 20 is under limited screw 15 spacing, after being separated by a distance, the first die joint 20 places wouldn't separated position.
After the first die joint 20 is separated by a distance, because dead man 3 is to coordinate with T-shaped groove with oblique side slide 5, so tiltedly side slide 5 is with tiltedly side slide mold insert 6 is under the motoricity of dead man, the motion that work and horizontal plane angle are 45 °, separates oblique side slide mold insert 6 and the product of injection mo(u)lding.Complete after side core-pulling spacing due to limited screw 13.Under the effect of injection moulding machine mould open power, overcome the friction force between A plate 4 and B plate 10, mould starts to open from the second die joint 30, and cover half mold insert 8 separates with dynamic model mold insert 9.Last injection machine ejects the product of injection mo(u)lding by ejecting mechanism.
During reset, injection machine resets to ejecting mechanism.Then start matched moulds, injection machine first contacts dynamic model mold insert 9, the second die joint 30 somatotype places start to close, in like manner, because cover half fixed head 2 and A plate 4 are also closed under the effect of mold clamping force, because dead man 3 is to be fixed on cover half fixed head 2, so also along with the closure at the first die joint 20 somatotype places resets simultaneously.Finally, overcome friction under the brute force of injection machine, cover half mold insert 8 is closed completely with dynamic model mold insert 9, carries out next injection moulding.
The oblique side core-pulling mechanism of desk lamp of the present utility model utilizes the thrust of ejecting mechanism to drive slanted pushing rod oblique movement, when plastic is pushed out the demoulding, by oblique side slide, is completed undercut and is loosed core action.The demoulding is simple, has improved production efficiency.
Certainly; more than explanation is only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the guidance of this description; that makes is allly equal to alternative, obvious form of distortion, within all dropping on the essential scope of this description, ought to be subject to protection of the present utility model.
