Abstract

The utility model discloses a heating device for a die head of a plastic profile extrusion die. The heating device comprises an extrusion die head (1), and a heating device body fixedly connected onto the extrusion die head, wherein the heating device body comprises an aluminum heating plate (2), an insulating plate (3) and a fixing plate (4); the aluminum heating plate (2), the insulating plate (3) and the fixing plate (4) are sequentially connected onto the extrusion die head (1); a socket (5) and socket guard plates (6) are fixedly connected onto the fixing plate (4); the socket guard plates (6) are positioned on two sides of the socket (5). According to the utility model, the structural design that the aluminum heating plate, the insulating plate and the fixing plate are combined is adopted, so the flatness of the aluminum heating plate is ensured, and the heating efficiency and use security are effectively improved.

Description

A kind of for the heater on extrusion mould head for plastic section bar

Technical field

The utility model relates to a kind of for the heater on extrusion mould head for plastic section bar.

Background technology

At present, all Rheology Devisings relevant to die head runner design, are all even thermally-stabilised as basic take the heat of melt.Extrusion die for Plastics Profiles head is heated by resistive device heating conventionally, and according to the external surface shape of die head, heater manufactures flat board or ring, realizes heating effect by screw and die surfaces close contact.What conventional square die head heating plate adopted conventionally is a kind of cast aluminium form of individual layer, and heater strip is present in only aluminium sheet, because the physical property of aluminium is relatively poor, wearing and tearing or buckling phenomenon easily occurs, and is difficult to guarantee the flatness of aluminium lamination face.And contact is well the basis that obtains homogeneous heating, otherwise the gap of heating plate and die surfaces will reduce the efficiency of this place's heating greatly; The existence of single layer aluminium sheet, has increased thereby the temperature that makes aluminium sheet both sides is identical all the time the danger that operator scalds; Single layer aluminium sheet easily makes because of the uneven exposed heater strip generation leaky of arranging; Because of the intensity difference of aluminium sheet, on general individual layer aluminium heating plate, socket cannot directly weld and Xuan Ze Pike connects, and when carrying heating plate, by direct contact base, easily causes rupture and make heating plate reprocess or scrap in the inclination Huo person Pike place of connecing of socket.

Utility model content

The purpose of this utility model is to provide a kind of for the heater on extrusion mould head for plastic section bar, improves the efficiency of heating surface and safety in utilization.

The technical solution adopted in the utility model is: a kind of for the heater on extrusion mould head for plastic section bar; comprise extrusion die and be fixedly connected on the heater on extrusion die; described heater comprises aluminium heating plate, insulation board and fixed head; described aluminium heating plate, insulation board and fixed head are fixedly connected sequentially on extrusion die; on described fixed head, be connected with socket and socket protective plate, described socket protective plate is positioned at the both sides of socket.

As further improvement of the utility model, described insulation board is mica sheet.

As further improvement of the utility model, described fixed head is corrosion resistant plate.

The beneficial effect that the utility model adopts is: the structural design that the utility model combines by aluminium heating plate, insulation board and fixed head, has guaranteed the flatness of aluminium heating plate effectively to improve the efficiency of heating surface and safety in utilization.

The specific embodiment

Below in conjunction with Fig. 1, Fig. 2, the utility model is described further.

As shown in Figure 1 and Figure 2; a kind of for the heater on extrusion mould head for plastic section bar; comprise extrusion die 1 and be fixedly connected on the heater on extrusion die; heater comprises aluminium heating plate 2, insulation board 3 and fixed head 4; aluminium heating plate 2, insulation board 3 and fixed head 4 are fixedly connected sequentially on extrusion die 1; on fixed head 4, be connected with socket 5 and socket protective plate 6, socket protective plate 6 is positioned at the both sides of socket 5.

In the utility model, insulation board 3 can be mica sheet, and fixed head 4 is corrosion resistant plate, and aluminium heating plate, mica sheet and corrosion resistant plate are fixedly connected on extrusion die by screw successively, is welded with socket and socket protective plate on corrosion resistant plate.

The utility model in use; the characteristic of mica sheet is insulation, high temperature resistant; have good thermal insulation, can guarantee the security that operating personnel use, the design of corrosion resistant plate can guarantee the flatness of aluminium heating plate heating surface; make homogeneous heating; improve the efficiency of heating surface, and the strength ratio aluminium of corrosion resistant plate heating plate hight, can be thereon in fact now Pike connect and the multiple processing method such as welding; the socket protective plate that is positioned at socket both sides welding on corrosion resistant plate, is convenient to placement and the carrying of heater.
