Description
Technical field
The present invention relates to hot runner system technical fields, more specifically, it relates to a kind of sprue bush of anti-wire drawing.
Background technique
Sprue bush is the runner component part for allowing the plastic material of melting to be injected into mould inside from the nozzle of injection molding machine, is
For connecting the metal fittings of molding die and injection molding machine；Product is in injection moulding process, and some mobility are preferable, viscosity is biggish
Material can generate wire drawing phenomenon at cast gate in disconnected glue, influence product beauty, cause product defect rate to increase, cause when serious
Can not continuous production, reduce production efficiency.
Existing anti-wire drawing sprue bush is as shown in Figure 4 comprising sprue bush ontology 1, feed opening 2 and cast gate 3, at cast gate 3
The direct through groove of one diamond shape of wire cutting, direct through groove install the disconnected of one piece of diamond shape perpendicular to the length direction of cast gate in direct through groove
Film 4, the both ends that direct through groove is located on 1 outer circle wall of sprue bush ontology are arranged two through-holes, are respectively used to the film 4 that breaks to diamond shape
Both ends carry out soldering, to complete the installation of disconnected film 4.
But the diamond shape slot on the disconnected film of such diamond shape and sprue bush is cut by line in processing technology and is process, line
Error can be had in correction center by cutting, and losenges is caused in cast gate center, not influence the mistake glue amount of cast gate two sides；Diamond shape
Disconnected film be easy to cause the adhesion of melting material since the smoothness that line cuts processing, higher cost, and surface cannot be guaranteed.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of sprue bush of anti-wire drawing, have
The advantage that installation accuracy is high, processing cost is low, melting material is not easily caused to be adhered.
To achieve the above object, the present invention provides the following technical scheme that
A kind of sprue bush of anti-wire drawing, including sprue bush ontology, the sprue bush ontology include feed opening and cast gate, the charging
Hole is coaxial with cast gate and communicates, it is characterised in that: the bottom wall of the feed opening is symmetrical arranged two about the axis centre of cast gate
Mounting groove, the mounting groove are communicated with cast gate, and jointly embedded with disconnected film in two mounting grooves, the disconnected film is perpendicular to peace
Fill the bottom wall in hole.
By using above scheme, two centrosymmetric mounting grooves are arranged by the bottom wall in feed opening, the film that breaks hangs down
Directly in two mounting grooves of insertion, disconnected film is enable to halve cast gate, keeps the mistake glue amount of disconnected film two sides impartial；Sprue bush sheet
Body only need to be positioned once, and just be capable of processing out two mounting grooves by CNC, and the processing is simple, and processing cost is low, and machining accuracy
It is high.
Preferably, the disconnected film is rectangular sheet, and the both ends of the disconnected film are located in two mounting grooves.
By using above scheme, the processing is simple for rectangular sheet, is polished by grinding machine, can improve surface accuracy, can avoid
The adhesion of melting material remains in the surface of disconnected film.
Preferably, the top surface that the disconnected film is located at outside mounting groove is flushed with the bottom wall of feed opening.
By using above scheme, the top surface of disconnected film is flushed with feed opening bottom wall, and melting material is made not remain in disconnected film
Around, convenient for cleaning.
Preferably, it is provided with the nozzle core communicated with cast gate in the feed opening, the nozzle core includes material path and crosses material mouth,
The diameter of the material path was greater than the diameter of material mouth.
By using above scheme, since feed opening bottom wall is plane, melting material is easy during flowing into cast gate from material reducing hole
Blockage phenomenon is passed through in cast gate by the way that nozzle core is arranged convenient for melting material.
Preferably, it is equal to be located at the diameter of film one end that breaks with the cast gate for the diameter for crossing material mouth.
By using above scheme, crosses material mouth and flushed with cast gate, seamlessly transit, melting material is made not remain in material mouth and pour
The intersection of mouth, convenient for being cleaned to sprue bush.

Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
The present embodiment is only explanation of the invention, is not limitation of the present invention, and those skilled in the art exist
It can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as in the present invention
Scope of the claims in all by the protection of Patent Law.
A kind of sprue bush of anti-wire drawing, as shown in the figure comprising sprue bush ontology 1, sprue bush ontology 1 include feed opening 2
With cast gate 3, feed opening 2 is coaxial with cast gate 3 and communicates, and the bottom wall of feed opening 2 is symmetrical arranged two about the axis centre of cast gate 3
Mounting groove 21, mounting groove 21 are communicated with cast gate 3, and mounting groove 21 is processed and formed at one time by CNC, and the processing is simple, at low cost, processing
