Description

A kind of novel de-stress injection mold
Technical field
The invention belongs to field of die equipment, and in particular to be a kind of novel de-stress injection mold.
Background technique
Injection mold is a kind of tool for producing plasthetics;Also plasthetics complete structure and accurate dimension are to confer to Tool.Injection molding is a kind of processing method used when producing certain complex-shaped components in batches.It refers specifically to melt heated Plastics by injection molding machine high pressure inject die cavity obtain formed products after cooling and solidifying.
In existing injection mold, including quick extrusion die and room temperature cooling mold, respectively there are superiority and inferiority, quick extrusion die The advantages of tool, is exactly that shaping speed is very fast, but the disadvantage is that need to be heat-treated molding product, to eliminate internal stress, Otherwise product can be deformed due to internal stress, and the advantages of room temperature cooling mold is formed cold without aftertreatment technology But it only needs simply to be polished after, it will be able to output finished goods, but the disadvantage is that molding time is longer, if to improve Output is merely able to improve production investment, very big pressure is thus caused for enterprise.
Summary of the invention
In order to solve the above technical problems, the present invention, which provides one kind, is capable of rapid shaping, it, can without post-processing step Improve the novel de-stress injection mold of the production efficiency of product.
To achieve the above object, the technical solution adopted by the present invention is that, a kind of novel de-stress injection mold, including mold Ontology, die ontology include melt chamber and forming cavity, and structural feature is that insulating layer is equipped between melt chamber and forming cavity;Institute It is equipped with shaping channel and cooling chamber in the forming cavity stated, shaping channel is able to carry out high-frequency vibration, and shaping channel is cooled chamber Package;The insulating layer is equipped with communication port, and the wall of communication port is equipped with the arc groove of several circular arrays, arc groove spiral shell Revolve progressive setting.
As a further improvement of the present invention, the diameter of the import of communication port is greater than the diameter of outlet, import and melt chamber Connection, outlet are connect with formed pipe.
As a further improvement of the present invention, heating sheet is connected in melt chamber, heating sheet is equipped with several sliding slots, Several Small Holes are equipped in sliding slot.
As a further improvement of the present invention, heating sheet is plugged in melt chamber, and the free end of heating sheet, which tilts down, to be set It sets.
As a further improvement of the present invention, heating sheet is several, several layered and parallel settings of heating sheet.
As a further improvement of the present invention, it is equipped with feed opening above melt chamber, is inserted with casing drum in feed opening.
As a further improvement of the present invention, casing drum is made of refractory metal material.
The beneficial effects of the present invention are: design is rationally, structure is simple, can be by the deformation in structure, to generate matter Become, not only improves only shaping speed, but also also avoid post-processing step, shorten the production time of product, and can also Enough improve the quality of product.

Specific embodiment
Explanation that the present invention will be further explained with reference to the accompanying drawing, but do not limit the scope of the invention.
As shown in Figure 1 to Figure 3, a kind of novel de-stress injection mold, including die ontology 1, die ontology 1 include melting Chamber 2 and forming cavity 3 are equipped with insulating layer 4 between the melt chamber 2 and forming cavity 3;It is logical that molding is equipped in the forming cavity 3 Road 5 and cooling chamber 6, shaping channel 5 be able to carry out high-frequency vibration, shaping channel 5 be cooled chamber 6 package;The insulating layer 4 It is equipped with communication port 7, the wall of communication port 7 is equipped with the arc groove 8 of several circular arrays, the progressive setting of 8 spiral of arc groove.
The diameter of the import of the communication port 7 is greater than the diameter of outlet, and import is connect with melt chamber, outlet and formed pipe Road 5 connects.
Heating sheet 9 is connected in the melt chamber 2, heating sheet 9 is equipped with several sliding slots 10, is equipped in sliding slot 10 Several Small Holes 11.
The heating sheet 9 is plugged in melt chamber 2, and the free end of heating sheet 9 tilts down setting;After facilitating melting Material flows into, and easy to disassemble, easy to clean.
The heating sheet 9 is several, the layered and parallel setting of several heating sheets 9;Different materials demands can be useful in.
It is equipped with feed opening 12 above the melt chamber 2, is inserted with casing drum 13 in feed opening 12.
The casing drum 13 is made of refractory metal material.
The present invention is vibrated by the high-frequency of shaping channel 5, and realization eliminates internal stress during formed product, can be with Saying is that molding and eliminating while carrying out internal stress, also, when material after melting is by the entrance shaping channel 5 of communication port 7, by It is equipped with the arc groove 8 of several circular arrays in the wall of communication port 7, arc groove spiral shell 8 revolves progressive setting, the communication port 7 Import diameter be greater than outlet diameter, so will form an extruding force, and can be when material enters shaping channel 5 Spiral winded type enters, and increases the homogeneous blend of material, improves quality.
