Abstract
The utility model discloses a kind of exhaust thimbles, including main exhaust and secondary exhaust pipe, the pair exhaust pipe is fixed on main exhaust head, the main exhaust offers main exhaust hole in the axial direction, the main exhaust side offers the gas outlet communicated with main exhaust hole, the pair exhaust pipe is in axial direction uniformly provided with secondary gas vent, and the pair exhaust pipe is consistent the aperture up and down of secondary gas vent by integral molding techniques.Exhaust thimble provided by the utility model saves production cost and makes end face that can be made into different shape.
Description
Technical field
The utility model relates to technical field of mold, specifically, being related to a kind of exhaust thimble.
Background technique
In injection moulding process, when solid-state plastic material is molten into liquid, generates a large amount of high temperature methane gas and enter mold cavity
It is interior, it may appear that the bad phenomenons such as gentle line are burnt in part, need to be solved by way of exhaust.Being vented thimble is exactly by mould type
Gas in mold cavity is discharged gas in intracavitary subrange.The head pair gas vent of existing exhaust thimble is interior
Big outer small tapering passage.In order to control the hole location diameter of outer surface, avoids hole location excessive and lead to the problem of material leakage, so exhaust
The shape on thimble head can only be made into planar end surface, can not be adjusted according to product shape.And using a period of time, if generated
Cutting is not can be carried out after blocking, secondary gas vent can become larger and generate material leakage after cutting, can only carry out whole replacement.
Utility model content
The purpose of this utility model is to provide a kind of exhaust thimbles, save production cost and make end face that can be made into not similar shape
Shape.
Technical solution used by exhaust thimble disclosed by the utility model is:
A kind of exhaust thimble, including main exhaust and secondary exhaust pipe, the pair exhaust pipe are fixed on main exhaust head, institute
It states main exhaust and offers main exhaust hole in the axial direction, the main exhaust side offers the outlet communicated with main exhaust hole
Mouthful, the pair exhaust pipe is in axial direction uniformly provided with secondary gas vent, and the pair exhaust pipe makes pair by integral molding techniques
The aperture up and down of gas vent is consistent.
Preferably, the end surface shape of the secondary exhaust pipe is cancave cambered surface, convex globoidal, plane or inclined-plane.
Preferably, the secondary exhaust tube material is metal powder.
Preferably, the secondary gas vent is square hole and side length is 0.05~0.15mm, the pair gas vent it
Between pore wall thickness be 0.1~0.2mm.
Preferably, the outer wall of the main exhaust and secondary exhaust pipe is equipped with DLC nano coating.
Preferably, the main exhaust material is SKH51 steel or SKD61 steel.
The beneficial effect of exhaust thimble disclosed by the utility model is: by main exhaust and secondary exhaust pipe is split type sets
Meter, and secondary exhaust pipe saves production cost by integral molding techniques, and is consistent the aperture up and down of secondary gas vent, it can
The end face of secondary exhaust pipe is made into the end face of jointing product shape according to installation site, and pair can be arranged after secondary exhaust hole plug
The end face of tracheae is cut, and the aperture of the secondary gas vent after cutting can keep cutting preceding state, avoids generating material leakage.
Detailed description of the invention
Fig. 1 is present invention exhaust thimble along axis view；
Fig. 2 is the partial enlarged view of the secondary exhaust pipe of present invention exhaust thimble；
Fig. 3 is the cross section of the secondary exhaust pipe of present invention exhaust thimble.
Specific embodiment
The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below:
Fig. 1-Fig. 3, a kind of exhaust thimble, including main exhaust 11 and secondary exhaust pipe 12 are please referred to, secondary exhaust pipe 12 is fixed
In 11 head of main exhaust, main exhaust 11 offers main exhaust hole 112 in the axial direction, 11 side of main exhaust offer with
The gas outlet 111 that main exhaust hole 112 communicates, secondary exhaust pipe 12 are in axial direction uniformly provided with secondary gas vent 123, secondary exhaust pipe
12 are consistent the aperture up and down of secondary gas vent 123 by integral molding techniques.
122 shape of end face of secondary exhaust pipe 12 is cancave cambered surface, convex globoidal, plane or inclined-plane, passes through different 122 shapes of end face
Shape makes secondary exhaust pipe 12 more jointing product shape, secondary exhaust pipe 12 is made to be applicable to the different surface shape of product.
Secondary 12 material of exhaust pipe is metal powder, and metal powder keeps secondary 12 fusing point of exhaust pipe high and hardness height, and metal
Powder and the degree of adhesion height of main exhaust 11 are easier to be combined with main exhaust 11,11 material of main exhaust for SKH51 steel or
SKD61 steel, material hardness is high and wearability is good.
Be square hole and side length of secondary gas vent 123 is 0.05~0.15mm, the square hole of side length within this range, gas
It can be smoothly discharged, while the leakage of injected plastics material can be prevented, product surface is made to keep smooth.Between secondary gas vent 123
Pore wall thickness is 0.1~0.2mm, makes secondary 12 sound construction of exhaust pipe and stays more spatial arrangement pair gas vents 123.
The outer ring 121 of main exhaust 11 and secondary exhaust pipe 12 sprays DLC nano coating, and coating one-sided thickness is 0.001~
0.002mm, DLC are writing a Chinese character in simplified form for diamond-like carbon film-coating, have high rigidity, wear-resistant and low-friction coefficient characteristic, and be vented
DLC nano coating has the function of self-lubricating to thimble in use, keeps die sinking and clamping process more smoothly.
In above scheme, by the split type design of main exhaust 11 and secondary exhaust pipe 12, and secondary exhaust pipe 12 passes through one
Body formed technology saves production cost, and is consistent the aperture up and down of secondary gas vent 123, can will be secondary according to installation site
12 end face 122 of exhaust pipe is made into the end face 122 of jointing product shape, and can be by secondary exhaust pipe 12 after the secondary blocking of gas vent 123
End face 122 is cut, and the aperture of the secondary gas vent 123 after cutting can keep cutting preceding state, avoids generating material leakage.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
