Description

A kind of conveniently stripped throw-out collar component

Technical field

The utility model is related to injection mould fields, and in particular to a kind of conveniently stripped throw-out collar component.

Background technology

Injection molding is to produce a kind of processing method used when certain complex-shaped components in batches.It refers specifically to be heated and melt The material of change injects die cavity by high pressure, after cooling and solidifying, obtains formed products.When injection molding, clamping mould is on injection molding machine, melting Plastics are injected into pattern intracavitary, and in intracavitary cooling and shaping, and then upper and lower mould separates, via ejection system by product from die cavity Mold is left in ejection, and last mold recloses to be molded next time, and entire injection moulding process is that cycle carries out.With plastics work The rapid development of industry and plastic products are answered in the popularization of the industrial departments such as Aeronautics and Astronautics, electronics, machinery, ship and automobile With requirement of the product to mold is also higher and higher, and traditional die design method can not adapt to current requirement.

In the moulding production process of existing mold industry, demoulding and ejection for injection-molded work are frequently with thimble come real Existing, i.e., injection molding machine ejection system drives thimble, is then attached to die ejection system.Thimble is usually to the applicable tool of ejection position There is a limitation, such as when thimble ejects face if it is inclined-plane or curved surface, thimble countersunk head will do positioning anti-rotation, and top surface will add ladder anti- Sliding, complex manufacturing process, the consuming time is longer, causes production efficiency low.And when need larger ejecting force or need by When large area thin-wall product ejects break away from moulds, the thimble ejection dynamics of thin bar type is small, is easy to make deformation of products, is impaired.

For a kind of substitute of thimble, a kind of top plate with large contact area, although realizing ejection great efforts The effect without damage with protection thin-walled large area product, but manufacturing cost is very high, difficulty of processing is relatively also bigger, no Suitable for small lot, the application of polytypic product.

Invention content

The problem of for background technology, in order to overcome the deficiencies of the prior art, the utility model, disclose a kind of convenience The technical issues of throw-out collar component of demoulding, thimble is not easy to eject when solving certain injecting products moldings in the prior art.

Multiple male model mold inserts, the public affairs are arranged on the male die core in a kind of conveniently stripped throw-out collar component, including male die core Mould mold insert integrally runs through male die core, throw-out collar is arranged between the male die core and male model mold insert, the throw-out collar can be along male die core and public affairs Hole sliding between mould mold insert, the throw-out collar includes sequentially connected first rank ring, second-order ring and third order PLL, and described the The outer diameter of second order loop is more than male die core aperture, and multiple fortune water holes, the male model is respectively set on the male die core and male model mold insert Multiple flow path grooves are also set up in benevolence；

Preferably, it is interconnected between the multiple flow path groove；

Preferably, the multiple flow path groove includes the level trough being laterally arranged and vertically arranged vertical channel；

Preferably, far from male die core one end setting protrusion flange on the male model mold insert；

Preferably, groove of the protrusion flange bottom end setting for positioning mold.

Advantageous effect acquired by the utility model is：

(1) the utility model is effectively protected product, both ensures product during demoulding by the way that throw-out collar is arranged Rapidly, it completely demoulds, also ensures the integrality of demoulding product.

(2) the utility model can realize mould fecund by the way that multiple male model mold inserts are arranged on male die core, once mold energy Enough produce Multiple Type, specification product.

(3) throw-out collar low manufacture cost, convenient material drawing easy processing, pushing course frictional force is small when product stripping is.
