Description
Technical field
A kind of mold work mechanism is the utility model is related to, more specifically, it relates to a kind of screw thread drift mould emptier.
Background technology
Machining internal thread is required on many injecting products, takes the processing mode of melting material solidification straight forming screw thread the most
Ideal, the thread helix face so generated is smoothly continuous, and uniformity is good, structural integrity, and intensity is high, but implements such a processing method
Because the screw thread of screw thread drift on mould is had been inserted into the sizing material of solidification when a maximum problem is mould opening, and mould is beaten
Typically only make simple rectilinear movement when opening, therefore screw thread drift can not depart from from injecting products, injecting products can not be smooth
The demoulding.Therefore, existing injecting products internal thread machining is generally all to use double of subdivision of screw thread, respectively by two half modules into
Type, or product stripping it is offline after separately drilling tapping method complete.But half module molding mode can cause spue line to fall in spiral shell
On line, thread helix face smoothness, continuity are all poor, and if the internal thread on injecting products biases, will give injection
The selection of product matched moulds line position brings very big difficulty；And the thread helix face that independent drilling tapping processes after formed product compared with
To be crude, and product breakage is easily caused during drilling tapping.Publication No. CN104015316A invention was in September in 2014 3 days
A kind of injection mold with oblique whorl work piece rotation ejection device is disclosed, including moving platen and base, the moving platen be remote
Middle part from base end is provided with cavity block, and the cavity block is connected with tooth form die cavity, type is provided with the middle part of the tooth form die cavity
Core, the core is also cross cavity block；The moving platen base end is provided with ram seat, and the ram seat pushes away provided with 2
Bar, and 2 push rods are distributed in core both sides, the free end of the push rod, which is provided with, pawls, described to pawl provided with two row's pawls, and two rows
The height of pawl is different, i.e., is connected to tooth form die cavity outer side edges including the high pawl of a row and the low pawl of a row, the free end of the high pawl,
The free end of the low pawl is connected to tooth form die cavity helicla flute side；Advantages of the present invention has：The characteristics of for oblique helicitic texture,
The rotation of tooth form die cavity is promoted workpiece is smoothly stripped while workpiece is ejected using just pawling, flexible rotation, release is laborsaving,
Demoulding efficiency is high.But the invention is only applicable to the column structures such as screw, helical gear and cylinder sets threaded part, for only
Some position has female injecting products, and the push rod provided using the invention can not realize product stripping.
The content of the invention
Using the mould of normal working practices, the processing mode for solidifying straight forming screw thread using melting material processes injecting products
Internal thread when, screw thread drift can not depart from from injecting products, and injecting products can not be smoothly stripped, to overcome this defect,
The utility model, which provides one kind, can be such that screw thread drift smoothly departs from from injecting products, so that what injecting products were smoothly stripped
Screw thread drift mould emptier.
