The utility model discloses simple structure when the drawing of patterns, passes through the make progress movable part of jack -up core of ejector pin by the elevating platform, makes injection moulding product on the core by ejecting, realizes rapid demoulding.
Description
Technical field
The utility model is related to a kind of injection mold, especially relates to a kind of injection mold carrying ejecting mechanism.
Background technology
Injection mold is the instrument producing plasthetics, is also to confer to the work of plasthetics complete structure and accurate dimension
Tool.Injection mo(u)lding is conventional processing method when producing some complex-shaped parts in batches, refers specifically to the material of thawing of being heated
Die cavity is injected by high pressure, after cooled solidification, obtains formed products.
Injection mold is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, cover half
It is arranged on the fixed form of injection (mo(u)lding) machine.In injection moulding, dynamic model and cover half closure constitute running gate system and die cavity, open
During mould, dynamic model separates with cover half to take out plastic products.
In existing lampshade Shooting Technique, place aluminium reflection shell first in cover half, subsequently into injection machine so that noting
Mould shell to cover outside aluminium reflection shell, to obtain complete lampshade, but there is a problem of being difficult the demoulding in injection moulding process.
Utility model content
For problems of the prior art, the utility model provides a kind of injection mold carrying ejecting mechanism,
Using the movable part of setting on core, the injecting products on core can be ejected, thus solving the problems, such as that the demoulding is difficult.
The concrete technical scheme that the utility model is adopted is as follows：
A kind of injection mold carrying ejecting mechanism, including cover half and be arranged on the multiple cores on cover half；
Each core is made up of fixed part and at least one movable part；
The lower section of described cover half is provided with lifting platform, and lifting platform has the guide post penetrating described cover half, and this guiding
Spring is cased with bar；
The activity of being fixed with described lifting platform runs through the push rod of cover half, and the top of push rod is connected with described movable part.
In the utility model, movable part may be located at middle part or the periphery of core, specifically can be arranged according to actual conditions.
As preferred, described moving part in the middle part of core, fixed part is set in outside movable part.
As preferred, described fixed position in the middle part of core, movable part is inlaid in the periphery of fixed part.
It is further preferred that described movable part is 3 or four being equidistantly spaced from.
As preferred, the bottom of described push rod is provided with location-plate, and lifting platform is provided with the positioning coordinating described location-plate
Groove, location-plate is placed in locating slot, so that it is determined that the position of each push rod.
As preferred, the top surface bolt of described lifting platform is fixed with pressing plate, and pressing plate is provided with the through hole allowing push rod to pass through,
Pressing plate can compress on location-plate and lifting platform, it is to avoid its displacement.
The utility model structure is simple, in the demoulding, is passed through the movable part of push rod jack-up core upwards by lifting platform, makes type
Injecting products on core are ejected, and realize fast demoulding.
Brief description
Fig. 1 is the structural representation of injection mold in the utility model.
Specific embodiment
Injection mold as shown in Figure 1, including the cover half 301 with lead 302 and be arranged on multiple on cover half 301
Core 304.
In the present embodiment, each core 304 is made up of fixed part 306 and four movable parts 305, and wherein, fixed part 306 is located at
The middle part of core, four movable parts 305 are equidistantly spaced from the periphery in core 304.
The lower section of cover half 301 is provided with lifting platform 309, and this lifting platform 309 can have elevating mechanism of the prior art to drive,
Such as hydraulic cylinder；The guide post 303 penetrating cover half 301 is had on lifting platform 309, and is cased with spring 308 on this guide post 303.
The activity of being fixed with lifting platform 309 runs through the push rod 307 of cover half 301, the top of every push rod 307 and core 304
Each movable part 305 connect, lifting platform 309 rise when, by each movable part 305 on push rod 307 upwards jack-up core 304,
The injecting products on core are made to be ejected, thus realizing the demoulding.
In the present embodiment, it is the position of fixed mandril 307, the bottom of push rod 307 is provided with location-plate 312, on lifting platform 309
It is provided with the locating slot 311 of cooperation location-plate 312, location-plate 312 is placed in locating slot 311, with to push rod fiber.In addition, rising
The top surface bolt of fall platform 309 is fixed with pressing plate 312, and pressing plate is provided with the through hole allowing push rod 307 to pass through, and pressing plate 312 can compress fixed
On position plate 312 and lifting platform 309, fixed mandril 307 is come with this.
The foregoing is only preferable implementation example of the present utility model, be not limited to the utility model, all in this reality
Within new spirit and principle, any modification, equivalent substitution and improvement made etc., should be included in guarantor of the present utility model
Within the scope of shield.
