The sliding block mechanism has a simple structure, is convenient to assemble, reduces damage of the sliding block, and improves production yield.
Description
Technical field
The utility model relates to the slide block mechanism of cantilever beam, relates in particular to a kind of large length to height ratio, guarantees slide block bending strength, indeformable slide block mechanism in injection moulding process.
Background technology
In some injecting products production processes, product is taken out blind hole with side, and side takes out blind hole length and blind hole aspect ratio is greater than 10, and causing side to take out slide block is a large length to height ratio cantilever beam.In mold injection process, side is taken out slide block can there is deflection deformation because the suffered injection pressure of upper and lower surface is different, causes the attenuation of product blind hole part local thickness, causes product to be shorted with blind hole height dimension overproof.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, a kind of large length to height ratio is provided, guarantees slide block bending strength in injection moulding process, indeformable cantilever beam slide block mechanism.
In order to solve above technical problem, the utility model provides a kind of slide block mechanism of cantilever beam, comprise male model plate and oil cylinder, described oil cylinder is fixedly installed on described male model plate, also comprise T-shaped slide block, push rod and slide block, described T-shaped slide block is arranged on described male model plate, and the head of described T-shaped slide block is fixedly connected with the cylinder chock plug of described oil cylinder, and the afterbody of described T-shaped slide block is an inclined-plane; The inclined-plane close contact of the bottom of described push rod and described T-shaped slider tail, the top of described push rod is connected with slider bottom.
The technical scheme that the utility model further limits is: also comprise the guide pad being arranged on described male model plate, described guide pad contacts with the bottom of described T-shaped slide block, a pilot hole is set on described guide pad, and described push rod passes described pilot hole and is sliding pair with described pilot hole inwall and is connected.
Further, described T-shaped slide block is embedded in the slide block slot of described male model plate, the long 2mm of length of T-shaped slide block described in the Length Ratio of described slide block slot.
Further, the bevel altitude of described T-shaped slider tail is 0.7mm.
The beneficial effects of the utility model are: the utility model provides a kind of cantilever beam slide block mechanism, when closing tight injecting glue, mould utilizes push rod support slipper, the distortion of anti-limited slip block effectively, subtract and hinder slide block damage, in mould pressurize, can guarantee that the integrality of product feature improves product yields period simultaneously; The utility model is simple in structure, easy to assembly, and security is good, has good application prospect.

The specific embodiment
embodiment 1
The utility model provides a kind of slide block mechanism of cantilever beam, structural representation as shown in Figure 1, comprises male model plate 6 and oil cylinder 1, and oil cylinder 1 is fixedly installed on male model plate 6, male model plate 6 is for slide block mechanism provides a supporting role, and the turnover of oil cylinder 1 by hydraulic oil provides power for cantilever beam slide block mechanism.
The slide block mechanism of cantilever beam of the present utility model also comprises T-shaped slide block 2, push rod 4, guide pad 3 and slide block 5.
T-shaped slide block 2 is arranged on male model plate 6, and is embedded in the slide block slot of male model plate 6, the long 2mm of length of the T-shaped slide block of Length Ratio of slide block slot.The head of T-shaped slide block 2 is fixedly connected with the cylinder chock plug of oil cylinder 1, and the afterbody of described T-shaped slide block 2 is an inclined-plane, and bevel altitude is 0.7mm.
The inclined-plane close contact of the bottom of push rod 4 and T-shaped slide block 2 afterbodys, the top of push rod 4 is connected with slide block 5 bottoms, when T-shaped slide block 2 moves back and forth, drives push rod 4 to move up and down.The top of push rod 4 is connected with slide block 5 bottoms, at mould, closes the tight injecting glue stage, and the bottom that push rod 4 fixes on slide block 5 leading portions plays a supportive role, and at mould packing stage, push rod is removed for 4 times, and the few glue in jogger hole place partly utilizes dwell pressure injecting glue.
The method that the utility model adopts oil cylinder to drive push rod to move back and forth, work schematic diagram when mould closes tight injecting glue as shown in Figure 2, structural representation during pressurize is as shown in Figure 3: when mould closes tight injecting glue, oil cylinder 1 resets, push rod 4 withstands slide block 5 front bottom end, play a supportive role, anti-limited slip block 5 is out of shape, and occurs the state of Fig. 2.When mould enters packing stage as shown in Figure 3, oil cylinder 1 is extracted out, by T-shaped slide block 2, drives push rod 4 recession glue position thickness 0.7mm, now by dwell pressure, makes few glue part circular hole be full of plastic cement, guarantees product feature integrality.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
