Description
Technical field
The utility model relates to a kind of mould, particularly a kind of sealing ring injection molding.
Background technology
At present, when the plastic of injection moulding side direction with protruding or groove, adopting undercut mechanism to realize the smooth demoulding of plastic is conventional mould structure form.But for the special plastic of some structures, secondary side is set to typing mechanism, bring very large difficulty by giving the manufacture of mould.According to the design feature of plastic, the somatotype of appropriate design mould order, utilizes the elastic deformation forced stripper mechanism of plastic to can yet be regarded as a kind of simple effective ways.Crawler belt sealing ring, material is thermoplastic polyurethane (TPU), and polyurethane (TPU) has the physical and mechanical properties of plastic processing performance and rubber concurrently, and it is wear-resisting, oil resistant, low temperature resistant, radiation resistance is particularly excellent.From plastic component structure, there are two parts to need to consider release problems time shaping, comprise: the W shape structure in outside and the U-shaped structure of inner side.W shape structure can undercut and the smooth demoulding of core-pulling mechanism; Inner side U-shaped is analyzed from plastic component structure, conventional undercut mechanism can not be adopted to have come, adopt lobe mould assembly core then complex structure; Consider that thermoplastic polyurethane (TPU) has good elasticity and certain impact strength, can Enforced stripping structure be adopted.There is joint fin after can preventing lobe mould assembly core from wearing and tearing like this, in turn simplify the structure of Design of Dies.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of sealing ring injection molding, can utilize the elastic deformation forced stripper mechanism of sealing ring
The utility model solves the technical scheme that its technical problem adopts: the utility model is by Bottom clamp plate, cushion block, push pedal fixed head, push pedal, push rod, dynamic model backing plate, Bottom clamp plate, moving platen, Angle Pin, top clamping plate, wedge, solid plate, Hough plate, sprue bush, sprue bush trim ring, upper moving-mould-core, dynamic model core retainer plate, lower moving-mould-core and guide pillar composition, is characterized in that: Bottom clamp plate respectively and cushion block, push pedal fixed head is connected, and push pedal fixed head is connected with push pedal, and push pedal is connected with one end of push rod, and the other end of push rod is through dynamic model backing plate, Bottom clamp plate is connected with moving platen, and the below of dynamic model backing plate is connected with cushion block, and the top of dynamic model backing plate is connected with Bottom clamp plate, and Bottom clamp plate is connected with moving platen, and top clamping plate is connected with solid plate by wedge, and Angle Pin is through solid plate, moving platen, Bottom clamp plate is connected with dynamic model backing plate, has Hough plate between moving platen and solid plate, and sprue bush trim ring is connected with sprue bush, sprue bush is connected with solid plate through top clamping plate, upper moving-mould-core is connected with solid plate, and dynamic model core retainer plate is connected with lower moving-mould-core, and guide pillar is through solid plate, moving platen, one end of Bottom clamp plate is connected with top clamping plate, and the other end is connected with dynamic model backing plate.
Owing to adopting technique scheme, the advantage that the utility model has and good effect are: practical.

Detailed description of the invention
In Figure of description 1, Bottom clamp plate (1) respectively with cushion block (2), push pedal fixed head (3) is connected, push pedal fixed head (3) is connected with push pedal (4), push pedal (4) is connected with one end of push rod (5), the other end of push rod (5) is through dynamic model backing plate (6), Bottom clamp plate (7) is connected with moving platen (8), the below of dynamic model backing plate (6) is connected with cushion block (2), the top of dynamic model backing plate (6) is connected with Bottom clamp plate (7), Bottom clamp plate (7) is connected with moving platen (8), top clamping plate (10) is connected with solid plate (12) by wedge (11), Angle Pin (9) is through solid plate (12), moving platen (8), Bottom clamp plate (7) is connected with dynamic model backing plate (6), Hough plate (13) is had between moving platen (8) and solid plate (12), sprue bush trim ring (15) is connected with sprue bush (14), sprue bush (14) is connected with solid plate (12) through top clamping plate (10), upper moving-mould-core (16) is connected with solid plate (12), dynamic model core retainer plate (17) is connected with lower moving-mould-core (18), guide pillar (19) is through solid plate (12), moving platen (8), one end of Bottom clamp plate (7) is connected with top clamping plate (10), the other end is connected with dynamic model backing plate (6).
Operation principle of the present utility model is: in order to make plastic melting physical efficiency be filled into preferably in the die cavity of mould, alleviate the intensity effect of weld mark to plastic, realizes automatically being separated of plastic and running gate system waste material, therefore mould adopts spot pouring mouth of hiding; Simultaneously in order to not affect assembly and use requirements, cast gate is located at inner side, and offers air discharge duct at parting gate zone line, so as not to because of be vented bad cause burn phenomenon.For deviating from the U-shaped of outside W shape and inner side on plastic smoothly, adopt sequential mold opening, twice-die-opening relies on its distortion pressure to deviate from.During die sinking, under the effect of injection machine, separately, spot pouring mouth is broken, and running gate system is coagulated material and stayed on dynamic model for dynamic model and cover half; Simultaneously under the effect of Angle Pin (9), Hough plate (13) is opened, for forced stripper mechanism provides certain space, further die sinking, injection machine push rod promotes push pedal (4), push rod promotes moving platen (8) under force and realizes push pedal (4) forced stripper mechanism, and plastic carries out the process of running gate system after falling into material frame.During matched moulds, Hough plate (13) resets under the effect of Angle Pin (9), and wedge (11) locks Hough plate (13) under mold clamping force; Moving platen (8) and push pedal (4) reset under the effect of mold clamping force, thus complete matched moulds process.
