Abstract

The utility model relates to a cooling and setting system of an extruder. The cooling and setting system comprises a cooling die, a setting die and a cooling water tank which are arranged in sequence, wherein a plurality of support frames used for supporting plastic profiles are horizontally installed in the cooling water tank at intervals; the cooling die comprises an upper die plate, medium die plates and a lower die plate; the medium die plates forming mirror symmetry are installed between the upper die plate and the lower die plate, thus forming a cavity; a plurality of water outlet troughs for cooling water to flow out are arranged on die plates on inner and outer edges of the cavity respectively. The cooling and setting system has the advantages and positive effects that a plurality of support frames are installed in the cooling water tank, so that the plastic profiles can be ensured not to bend or deform in a cooling process, thus effectively ensuring the cooling quality of the plastic profiles; by arranging a plurality of water outlet troughs on the die plates on the upper and lower surfaces of the cavity respectively, the cooling die and the setting die can cool the plastic profiles uniformly and quickly; the cooling and setting system is scientific and reasonable in design, has a simple structure and effectively improves the quality and work efficiency of the profiles.

Description

A kind of extruder cooling and shaping system

Technical field

The utility model belongs to technical field of mold, specifically, is a kind of extruder cooling and shaping system.

Background technology

Cooling and shaping system is most important for plastic material, first must design a set of cooling shaping mould, and then section bar be put into bosh and carry out cooling.But traditional cooling shaping mould complex structure and fixed effect are poor, Surface of profile is prone to fold; In addition, because bosh is longer, cause section bar carrying out bending when cooling, thereby affect section quality.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, extruder cooling and shaping system that cooling and shaping is effective is provided.

Scheme of the present utility model is achieved in that

A kind of extruder cooling and shaping system, comprises the cooling die, shaper and the bosh that set gradually, and in described bosh, lateral separation is provided with multiple bracing frames for supporting plastic section bar;

Described cooling die comprises cope match-plate pattern, middle template and lower bolster, and the symmetrically arranged middle template of mirror image is installed between described cope match-plate pattern and lower bolster, thereby forms die cavity, is shaped with respectively the effluent trough that multiple Cooling Waters flow out in the template of the inside and outside edge of described die cavity.

And the upper end of support frame as described above is shaped with a rectangular recess, the integral middle of this rectangular recess is shaped with an arc convex.

And, two the symmetrical sides in the cope match-plate pattern of described cooling die and lower bolster one end are vertically provided with respectively two groups of water inlet pipes, cope match-plate pattern and the lower bolster other end that should water inlet pipe be separately installed with to outlet pipe, and the lower surface of described cope match-plate pattern and middle template is corresponding is shaped with many effluent troughs that are communicated with described water inlet pipe; The upper surface one of described lower bolster is shaped with the core rod of a cylindrical structural, in this core rod, be shaped with a cavity that holds cooling water, this cavity is communicated with described water inlet pipe, is shaped with many lower bolster effluent troughs that are communicated with described water inlet pipe on the core surface of corresponding described die cavity and lower bolster.

And the length of described cooling die is 8cm, the length of shaper is 25cm.

Advantage of the present utility model and good effect are:

Multiple bracing frames are installed in the bosh of native system, can guarantee that plastic material is not bending, indeformable in cooling procedure, has effectively guaranteed the cooling quality of plastic material; Cooling die and shaper be by being shaped with respectively multiple effluent troughs in the template on the upper and lower surface at die cavity, thereby can carry out evenly plastic material, cooling fast, not only shortens molding cycle, and save energy consumption.The utility model design science is reasonable, simple in structure, has effectively improved quality and the operating efficiency of section bar.

The specific embodiment

Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail.

A kind of extruder cooling and shaping system, as shown in Figure 1, comprise the cooling die 4, shaper 3 and the bosh 1 that set gradually, the plastic material of extruding by extruder (not shown) is first by after cooling die, shaper, put into again bosh and carry out fully coolingly, can obtain the plastic material of moulding.

Innovative point of the present utility model is:

1, in described bosh, lateral separation is provided with multiple bracing frames 2 for supporting plastic section bar.

2, described cooling die comprises cope match-plate pattern 8, middle template 10 and lower bolster 11, the symmetrically arranged middle template of mirror image is installed between described cope match-plate pattern and lower bolster, as shown in Figure 4, thereby form the die cavity 14 of " Ω " shape, in the template of the inside and outside edge of described die cavity, be shaped with respectively the effluent trough that multiple Cooling Waters flow out.

In the present embodiment, the upper end of support frame as described above is shaped with a rectangular recess 6, the integral middle of this rectangular recess is shaped with an arc convex 5, bracing frame in the present embodiment accompanying drawing is two, in the time of plastic material process cold rinse bank, bracing frame can support and prevent bending, has effectively guaranteed plastic material cooling effect.

As shown in Figure 3, Figure 4, two the symmetrical sides in cope match-plate pattern and lower bolster one end are vertically provided with respectively two groups of water inlet pipes 9 to the structure of described cooling die, and cope match-plate pattern and the lower bolster other end that should water inlet pipe be separately installed with to outlet pipe 12.The lower surface of described cope match-plate pattern and middle template is corresponding is shaped with many effluent troughs 15 that are communicated with described water inlet pipe, and as shown in Figure 5, flowing out cooling water by effluent trough can carry out cooling to the outer fringe surface of die cavity; The upper surface one of described lower bolster is shaped with the core rod 13 of a cylindrical structural, in this core rod, be shaped with a cavity that holds cooling water, this cavity is communicated with described water inlet pipe, on the core surface of corresponding described die cavity and lower bolster, be shaped with many lower bolster effluent troughs 16 that are communicated with described water inlet pipe, flowing out cooling water by lower bolster effluent trough can carry out cooling to the inner peripheral surface of die cavity.In the template on the inside and outside edge surface of described cooling die die cavity, be shaped with respectively multiple effluent troughs, therefore can play the object of uniform decrease in temperature, guaranteed that plastic material is cooling and its shrinkage factor is consistent fast.

In order to obtain best cooling effect, the length B of described cooling die is 8cm.

The structure of described shaper and described cooling die is basic identical, the inside and outside edge surface of this die cavity is shaped with the effluent trough that multiple Cooling Waters flow out equally, therefore the application is no longer described in detail, and in order to obtain best cooling effect, the length C of this shaper is 25cm.

For convenient disassembly, one handle 7 is installed in described cope match-plate pattern upper surface.

It is emphasized that; embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model comprises and is not limited to the embodiment described in the specific embodiment; every other embodiments that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
