Description
Technical field
Injection mold is the utility model is related to, more particularly to the injection mold Automatic-falling formula side of curved hollow plastic article
Hide flash Jiao Kou on side.
Background technology
In injection mold, if working of plastics is curved hollow tube, or a portion is formed with curved hollow tube, due to nothing
Method extracts curved hollow space out by pulled core structure, it is therefore desirable to the sizing material blowout inside curved part is turned into hollow using air valve
Working of plastics, in existing injection mold, flash groove is located at the side of curved hollow tube, in flash groove and the mould of curved hollow tube
Material overflow port is formed between chamber, the material overflow port is located at the upper surface of core, and the sizing material of curved part blowout flows into flash groove through material overflow port
Middle storage, after working of plastics is cooled and shaped, the flash of flash groove and material overflow port is also cooled and shaped as waste material, and working of plastics is through flash
The waste material in waste material connection flash groove in mouthful（That is working of plastics and waste material is connected）, after working of plastics and waste material eject together,
Secondary operation is needed, will be cut off at waste material, processing trouble, reduces production efficiency, increases labor strength, and removal of place influences
Product is attractive in appearance.
The content of the invention
The shortcomings that the purpose of this utility model is to overcome prior art to exist, there is provided a kind of curved part blow it is hollow after,
Waste material in flash groove is separated with working of plastics, and waste material automatic ejection demoulding, easy to process after die sinking, improves production efficiency, subtracts
Light labor strength, saves labour turnover, and the injection mold that small curved hollow plastic article is influenceed on working of plastics profile is automatic
Hide flash Jiao Kou for separation-type side.
The latent flash Jiao Kou in the injection mold Automatic-falling formula side of the curved hollow plastic article of the utility model technical side
Case is：Including upper compound plate and lower compound plate, die cavity is set under upper compound plate, support block is set on lower compound plate, on the lower compound plate between support block
Ejector retainner plate, lower ejector retainner plate and thimble in setting, core is set on support block, the working of plastics for having injection molding between core and die cavity,
Curved hollow tube is formed with working of plastics, the side of curved hollow tube is provided with overfall, is formed with flash groove in core, in flash groove
There is the waste material blown out in curved hollow tube, it is characterised in that：Oil cylinder perforation, the spilling of curved hollow tube are provided with described core
Mouth is located at lower section, and oil cylinder perforation is corresponding with the overfall of the curved hollow tube of working of plastics, and needle-valve oil cylinder, needle-valve are set under core
The piston rod of oil cylinder is perforated with oil cylinder and overfall is engaged, and is located in core in flash groove and is provided with latent material overflow port, hides
The side wall that material overflow port is perforated with oil cylinder communicates.
The utility model discloses a kind of latent flash glue in the injection mold Automatic-falling formula side of curved hollow plastic article
Mouthful, it is mainly characterized by being provided with latent material overflow port in flash groove, oil cylinder perforation, upper end and the song of oil cylinder perforation is provided with core
The mould cavity of shape hollow tube, the side wall of oil cylinder perforation are communicated with latent material overflow port, and needle-valve oil cylinder, needle-valve oil are set under core
The piston rod of cylinder stretch into oil cylinder perforation in, when mould injection when, the piston rod of needle-valve oil cylinder pushes up upwards, the upper end of piston rod with
Oil cylinder perforation is equal, and after mould completes injection, needle-valve oil cylinder drives piston rod to move down, and makes die cavity, oil cylinder perforation, dives
Volt material overflow port, flash groove communicate, and now air valve is inside the curved part of working of plastics to blowing, make sizing material inside curved part by
Gradually flowed into from oil cylinder material overflow port of perforating and hide in flash groove, until the inside of curved part is blown hollow, obtain curved hollow tube,
Now the piston rod of needle-valve oil cylinder pushes up again up, blocks oil cylinder perforation, makes curved hollow tube and the waste material in flash groove mutual
Separation, after working of plastics and waste material are each cooled and shaped, last mould molds, and by the multiple thimbles of upper and lower ejector retainner plate drive, will mould
Materials and parts and waste material eject abjection respectively.The latent flash glue in the injection mold Automatic-falling formula side of the curved hollow plastic article of this programme
Mouthful, by core set oil cylinder perforate and material overflow port of hiding, by working of plastics blow it is hollow after, utilize the piston cylinder of needle-valve oil cylinder
Oil cylinder perforation is blocked, so that during die sinking ejection, working of plastics is automatically separated with waste material, without the useless of secondary operation excision blowout
Material, it is easy to process, production efficiency is improved, labor strength is reduced, saves labour turnover, and is cut relative to caused after excision
Trace, plastic part surface are more attractive in appearance.
Hide flash Jiao Kou for the injection mold Automatic-falling formula side of the curved hollow plastic article of the utility model, and described is latent
The aperture that volt material overflow port is located at flash groove side is more than the aperture that latent material overflow port is located at oil cylinder perforation side.Latent material overflow port position
It is larger in the aperture of flash groove side, when by the ejection of the waste material of spilling, be advantageous to waste material in latent material overflow port from flash groove
Deviate from side.Guide pillar is set between described lower compound plate and core, guide hole, guide hole and guide pillar phase are provided with upper and lower ejector retainner plate
Coordinate.There are guide pillar and guide hole, guide effect is played in the up and down action to upper and lower ejector retainner plate, and it is accurate to ensure that it is moved up and down.
