Description
Technical field
The utility model relates to a kind of screw thread demolding structure.
Background technology
As everyone knows, present mould is as manufacturing core, become requisite apparatus in manufacturing field, mould is a kind of Cavity tool having definite shape and size, with system various in mould or auxiliary body with the use of, various high-temperature liquid material is filled in mold cavity, the industrial part with specific shape, size function and quality can be produced.As a kind of, screw thread connects that fit structure is present also general to be used in product structure, in the process of designing mould, how threaded mold to be extracted from product out the outstanding problem become in mould Production design process, also occur that some take out helicitic texture now, but many existence extraction effects are undesirable when concrete use, when particularly often occurring extracting out, product is together with taking out helicitic texture and involving, and does not come off completely.
Utility model content
In view of this, when the purpose of this utility model is to provide a kind of screw thread demoulding, extract out satisfactory for result, a kind of screw thread demolding structure of product together with taking out helicitic texture and can not involving.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of screw thread demolding structure, comprise an oil cylinder, and oil cylinder fixed mount, described oil cylinder fixed mount comprises the upper mounted plate and bottom plate that are parallel to each other, and the guide post be fixedly connected between upper mounted plate and bottom plate, a movable plate be slidably connected with described guide post is also provided with between wherein said upper mounted plate and described bottom plate, described movable plate upper end center position place is connected with described oil cylinder top, described movable plate lower end is also connected with one and stretches out the tooth bar stretched out outside described bottom plate, described tooth bar engages with a driving gear, the described driving gear left and right sides is engaged with a driven gear respectively, described driven gear both sides are engaged with a thread core respectively, described thread core comprises mandrel and mandrel thread tap, and be fixedly connected on described mandrel periphery and with described driven gear meshed gears cover, described mandrel inside is in hollow form, its one end is connected with a gas channel, the other end communicates with the external world.
Preferably, above-mentioned a kind of screw thread demolding structure, the driven gear of the wherein said driving gear left and right sides is in same level position.
Preferably, above-mentioned a kind of screw thread demolding structure, the thread core of wherein said driven gear both sides is in same level position.
Preferably, above-mentioned a kind of screw thread demolding structure, thread pitch place, wherein said mandrel thread tap periphery is provided with some airflow holes.
Compared with prior art, the utility model technique effect is mainly reflected in: during the screw thread demoulding, hydraulic oil cylinder driving tooth bar, rack drives driving gear, driving gear drives driven gear, driven gear drives thread core to rotate through mandrel thread tap and completes the screw thread demoulding, simultaneously, mandrel inside is in hollow form, its one end is connected with a gas channel, and the other end communicates with the external world, and air-flow passes through mandrel empty internal along gas channel, and act on product by mandrel thread tap, make product and take out helicitic texture to depart from completely.
