Abstract
The utility model discloses a casting moulding metal heater for an injection mould hot runner system, which comprises a sleeve body. A helical integrated coil is embedded in a sleeve wall of the sleeve body, and one end of the integrated coil is provided with an extension line and a connector lug at the head portion of the extension line. The sleeve wall of the sleeve body is provided with a line placing groove parallel with the axial direction of the sleeve body, and the line placing groove penetrates through the sleeve wall of the sleeve body. By means of the casting moulding metal heater for the injection mould hot runner system, due to the fact that the heating and temperature-sensing integrated coil is embedded into the sleeve body through a casting method, on one hand, the integrated coil is protected from being damage by outside, and on the other hand, heating efficiency of the heater is improved. Simultaneously, under the condition of a long nozzle, a plurality of casting moulding metal heaters for the injection mould hot runner system further can be connected together for use.
Description
Technical field
The utility model relates to a kind of injection mold hot runner system, implants the metal heater in the sleeve body to integrated heater coil and temperature-sensitive coil through the mode of casting specifically.
Background technology
Compare with traditional cold runner mould; Hot runner mould has advantages such as economizing in raw materials, enhances productivity and is extensively adopted; The heater that is set in nozzle outer surface is the critical piece in the hot runner mould, and it is made up of sleeve body and the heater coil that is wrapped in the sleeve body outer surface usually, and is more efficient to the heating of sleeve body for making heater coil; Usually the outer surface at sleeve body is provided with spiral helicine groove; Embed heater coil in the groove, and in heater coil, be integrated with the temperature-sensitive coil, the temperature of heater is monitored in real time and controlled so that be implemented in the process of heating.The embedded heater of existing this form is on the one hand when heater during in work, owing to heater coil is different with the material of sleeve body; The initial stage of heating and the insulation latter stage; Heater coil is also different with the temperature of sleeve body, causes heater coil different with the amount of expanding with heat and contract with cold of sleeve body, thereby makes heater coil generation stress damaged easily; Simultaneously; Heater coil also has a face not contact with sleeve body, also has the part heat to lose in vain, and integrated heater coil that exposes and temperature-sensitive coil also receive damage of external force easily.
The utility model content
For overcoming above-mentioned defective, the utility model aims to provide a kind of mode through casting and implants integrated heater coil and temperature-sensitive coil in the sleeve body, makes four faces of heater coil all contact the metal heater that the efficiency of heating surface is improved with sleeve body.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of injection mold hot runner system uses the cast molding metal heater; Comprise a sleeve body; The barrel of said sleeve body has been implanted into the helical form integrated coil, and an end of said integrated coil has the connector lug of extended line and extended line head.
Have a trunking with the sleeve body axially parallel on the barrel of said sleeve body, said trunking connects the barrel of sleeve body.
Adopted the injection mold hot runner system of the utility model to use the cast molding metal heater; Owing to implanted heating and temperature-sensitive integrated coil in the sleeve body through the mode of casting, protected integrated coil to exempt from extraneous destruction on the one hand, on the other hand; The efficiency of heating surface of heater is improved; Simultaneously, under the long situation of nozzle, the use that can also a plurality ofly link together of the heater of the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the perspective view of the utility model;
Fig. 3 is the integrated coil structural representation of the utility model.
Among the figure: 1-sleeve body, 2-integrated coil, 3-extended line, 4-connector lug, 5-trunking.
The specific embodiment
Like Fig. 1-shown in Figure 3, the utility model discloses a kind of injection mold hot runner system and use the cast molding metal heater, comprise a sleeve body 1; Its innovative point is that mainly the barrel of said sleeve body 1 has been implanted into helical form integrated coil 2, and said integrated coil 2 is meant and is integrated with heater wire and thalposis line in the coil, can heat sleeve body 1 through integrated coil 2; Also can monitor simultaneously the temperature of sleeve body 1 in real time; So that in time heater wire is switched on or dead electricity, in the operating temperature range of setting, the sleeve body 1 of the metal heater of the utility model needs to process through the mode of cast molding the temperature of maintainance set cylindrical shell 1 all the time; When carrying out sleeve body 1 cast molding; Be placed on integrated coil 2 earlier and water in the mold, like this, after sleeve body 1 cast molding is accomplished; The active section of integrated coil 2 is implanted in the cylindrical shell of sleeve body 1, and an end of said integrated coil 2 has the connector lug 4 of extended line 3 and extended line 3 heads.
For long nozzle; Only can't realize nozzle-integrated coating heating with the metal heater an of the utility model; At this moment; Usually needing the metal heater of employing more than two or two axially to link together is coated on the outer surface of nozzle; Equal for the extended line 3 that makes a back metal heater with sleeve body 1 excircle of previous metal heater, have a trunking 5 with sleeve body 1 axially parallel on the barrel of the injection mold hot runner system of the utility model with the said sleeve body 1 of cast molding metal heater, said trunking 5 connects the barrel of sleeve bodies 1.The big palpulus of the sectional dimension of trunking 5 is slightly larger than the sectional dimension of extended line 3, like this, can the extended line 3 of a back metal heater place previous metal heater trunking 5 in, both neatly unified, again extended line 3 is had certain protection simultaneously.
Claims (2)
1. an injection mold hot runner system uses the cast molding metal heater; Comprise a sleeve body (1); The barrel that it is characterized in that said sleeve body (1) has been implanted into helical form integrated coil (2), and an end of said integrated coil (2) has the connector lug (4) of extended line (3) and extended line (3) head.
2. injection mold hot runner according to claim 1 system uses the cast molding metal heater; It is characterized in that having on the barrel of said sleeve body (1) trunking (5) with sleeve body (1) axially parallel, said trunking (5) connects the barrel of sleeve body (1).
