Description
Technical field
The utility model belongs to plastic granulator technical field, and specifically one kind is mainly for temperature sensitive kinds plastics
The die head of the comminutor of processing.
Background technology
Plastic extruder belongs to one of type of plastic processing machinery, and screw extruder is the pressure generated by screw rod rotation
Power and shearing force can allow material fully to carry out plasticizing and uniformly mixing, be molded by mouth mold.Screw rod be extruder compared with
For important and crucial component, the quality and productivity of the plastic products of production all directly depend on machine melt extrusion temperature
Uniformity and pressure, the stability of extrusion capacity, and these parameters all directly depend on the structural behaviour of screw rod.It is corresponding with screw rod
Be die head, existing comminutor, for the processing of temperature-sensitive plastic, it is often necessary to replace filter screen, increase is produced into
This, reduces production efficiency.In addition, there is also the risks of material leakage.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of die heads of comminutor, reduce material stock in mould,
Material leakage is prevented, production efficiency is improved.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of die head of comminutor, including monoblock type external mold, the monoblock type external mold is interior to be equipped with embedded honeycomb boards,
There are several through-holes on the embedded honeycomb boards, the wear-resisting pressure ring positioned at embedded honeycomb boards both sides is equipped in monoblock type external mold,
Monoblock type external mold inner wall is equipped with the removable middle plate of double-station, embedded honeycomb boards and the removable middle plate attaching of double-station, monoblock type external mold
Internal orifice end be installed with outer ring cutting die head, be equipped in monoblock type external mold has transition rings with outer ring cutting mould, wear-resisting pressure ring attaching respectively.
The through-hole of the embedded honeycomb boards is conical through-hole.
The wear-resisting pressure ring is made of phosphor bronze.
The monoblock type external mold is equipped with step screens, and outer ring cutting die head is equipped with convex jacking block, and convex jacking block, which supports, is mounted in step
In screens.
The outer ring cutting die head passes through bolt and monoblock type external mold installation locking.
The utility model reduces material stock in mould, prevents material leakage, improves production efficiency.By using monoblock type external mold, subtract
The overall dimensions of small die head avoid the problem that material leakage and the excessive frosted damage of middle plate by the way that the wear-resisting pressure ring of phosphor bronze is arranged.
Description of the drawings
Attached drawing 1 is the utility model and the cross-sectional view after screw rod assembly.
Specific implementation mode
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the utility model, below
The utility model is described in further detail with specific implementation mode in conjunction with attached drawing.
As shown in Fig. 1, the utility model discloses a kind of die head of comminutor, including monoblock type external mold 2, described
It is equipped with embedded honeycomb boards 7 in monoblock type external mold 2, there are several through-holes 71 on the embedded honeycomb boards 7, in monoblock type external mold 2
Equipped with the wear-resisting pressure ring 3 positioned at 7 both sides of embedded honeycomb boards, 2 inner wall of monoblock type external mold is equipped with the removable middle plate 4 of double-station, embedded
Formula honeycomb boards 7 and removable 4 attaching of middle plate of double-station, the internal orifice end of monoblock type external mold 2 are installed with outer ring cutting die head 6, outside monoblock type
Be equipped in mould 2 respectively with outer ring cutting mould 6, the transition rings 5 of 3 attaching of wear-resisting pressure ring.The through-hole of embedded honeycomb boards is conical through-hole,
Multiple conical through-hole laid out in parallel, and from screw rod one end towards the descending variation in the first end of circumscribed ring moulds.Double-station can
Plate engages installation with embedded honeycomb boards in shifting.
The wear-resisting pressure ring is made of phosphor bronze, improves wear-resisting property.
The monoblock type external mold is equipped with step screens, and outer ring cutting die head is equipped with convex jacking block 61, and convex jacking block, which supports, is mounted in platform
In rank screens, it is easily installed.
The outer ring cutting die head passes through bolt and monoblock type external mold installation locking.
The utility model is integrally formed manufacture, can effectively reduce overall dimensions by monoblock type external mold.Also utilize cone
The honeycomb boards of shape through-hole can save frequent the problem of replacing filter screen, extend the replacement frequency of die head filter screen.This practicality
Novel monoblock type external mold passes through the flanged joint on the machine barrel of bolt and screw machine.The front and back configuration of the removable middle plate of double-station is resistance to
Pressure ring is ground, the pressure adjustable of entire die head avoids the removable middle plate of double-station and is excessively abraded.It is especially suitable by designing above
The processing of temperature sensitive kinds plastics is closed, material stock in mould is reduced, avoids runner dead angle.
It should be noted that these are only the preferred embodiment of the utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, still
It can modify to the technical solution recorded in previous embodiment or equivalent replacement of some of the technical features,
But within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the scope of protection of the utility model.
