Description
Technical field
The utility model relates to mould field, particularly relates to a kind of mould of plastic extruder.
Background technology
In plastic extruding forming equipment, plastic extruder is referred to as main frame usually, and the follow-up equipment plastic extruding forming machine supporting with it is then called subsidiary engine.Plastic extruder can with tubing, film, handful material, monofilament, flat filament, strap, squeeze the various plastic shaping subsidiary engines such as net, plate (sheet) material, profile shapes, granulation, cable be coated and mate, form various plastic extruding forming production line, produce various plastic products.When producing various plastic products, mainly controlled the forming shape of goods by the mould of plastic extruder.When producing plastic pipe, need to adopt mouth mould and core, mouth mould controls the outer shape of plastic pipe, and core controls the interior shape of tubing.Mouth mould under prior art condition and core mold structure complexity, and core does not possess cooling structure, at plastic pipe molding weak effect, plastics and die surface are easily sticky glutinous.
Utility model content
The utility model is in order to overcome deficiency of the prior art, provide a kind of mould of plastic extruder, the utility model overcomes the baroque defect of tubular article formation mould of plastic extruder, core of the present utility model is provided with cooling structure simultaneously, contribute to lowering the temperature in forming process, strengthen molding effect.
The utility model is achieved through the following technical solutions:
A mould for plastic extruder, comprises a mouthful mould, core, and described mouth mould is fixed on the head of plastic extruder, and core is fixed on mouthful between mould and head; Described core comprises the die head that two ends are taper, the shaping straight-bar of taper connection one of die head one end, described core also comprises retainer plate, connecting rod, is connected between retainer plate with die head by connecting rod, described connecting rod is provided with ingate, and described ingate is communicated with the access aperture on head; Shaping straight-bar is provided with outlet opening, ingate and outlet opening thereof.
Described mouth mould front end is provided with positioning end, and positioning end is inserted in the groove on head.
Pad is respectively arranged with between described retainer plate and head, between retainer plate and mouth mould.
Compared with prior art, the beneficial effects of the utility model are: core of the present utility model comprises retainer plate, connecting rod between retainer plate and core is provided with ingate, cooling medium can be injected in ingate by the access aperture on head, realize lowering the temperature to core.Simultaneously core is fixed on mouthful between mould and head by retainer plate, quick and easy for installation.
Accompanying drawing explanation
Fig. 1 is the structural representation after core of the present utility model, the installation of mouth mould;
Fig. 2 is the front view of core of the present utility model;
Fig. 3 is the left view of core of the present utility model.
In figure: 1, head; 2, reinforced chamber; 3, ingate; 4, connecting rod; 5, pad; 6, access aperture; 7, sealing ring; 8, mouth mould; 9, fixing hole; 10, molding runners; 11, shaping straight-bar; 12, outlet opening; 13, core; 14, positioning end; 15, retainer plate.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The mould of described a kind of plastic extruder, as shown in Figure 1, comprise mouthful mould 8, core 15, described mouth mould 8 is fixed on the head 1 of plastic extruder, sealing ring 7 is provided with between mouth mould 8 and head 1, mouth mould 8 is utilized by fixing hole 9 and is bolted on head 1, and core 13 is fixed between mouthful mould 8 and head 1.Described core 13 comprises the die head that two ends are taper, the shaping straight-bar 11 of taper connection one of die head one end, and shaping straight-bar 11 is inserted in the hole on mouthful mould 8, on the outer wall of shaping straight-bar 11 and mouth mould 8 hole inwall between form molding runners 10; The die head of core 13 is towards the reinforced chamber 2 on head 1, and the plastics of hot melt flow to molding runners 10 from the gap between die head and mouth mould 8, cooling forming in molding runners 10.
As shown in Figure 2 and Figure 3, described core 13 also comprises retainer plate 15, connecting rod 4, and retainer plate 15 is connected by connecting rod 4 with between die head, connecting rod 4 is provided with ingate 3, and ingate 3 is communicated with the access aperture 6 on head 1; Shaping straight-bar 11 is provided with outlet opening 12, and ingate 3 is communicated with outlet opening 12.In core 13, inject cooling medium by the access aperture 6 on head 1, core 13 is lowered the temperature, the heat in simultaneously stability molding runners 11 in plastic raw materials, thus contribute to tubing cooling forming.
Described mouth mould 8 front end is provided with positioning end 14, and positioning end 14 is inserted in the groove on head 1.Pad 5 is respectively arranged with between retainer plate 15 and head 1, between retainer plate 15 and mouth mould 8.Pad 5 is set, prevents cooling medium from entering in the plastics of hot melt.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
