Abstract
The utility model relates to a heating device of an automobile door sheet decorative piece mold flow channel, which comprises a fixed mold motherboard and a movable mold motherboard. The fixed mold motherboard is provided with a pouring port locating ring and is connected with a fixed mold through a hot flow channel fixing plate. A nozzle is arranged in the fixed mold. A hot flow channel frame is arranged between the fixed mold motherboard and the fixed mold. A hot flow channel in the hot flow channel frame is communicated with the nozzle. The movable mold motherboard is provided with an ejection mechanism and is connected with a movable mold through a support block. The clearance between the movable mold and the fixed mold forms a mold cavity. The sprayer of the nozzle faces the mold cavity. The utility model is characterized in that a heating board is arranged in the hot flow channel frame and a heating ring is enwound outside the nozzle. In the scheme, the material flow temperature is high and the fluidity is good. Even at the horn hole-intensive position, the mold cavity can be filled and inadequate injection molding is avoided. The utility model does not have weld marks, reduction and other disadvantages.
Description
Technical field
The utility model relates to the mould that is used to produce the automobile door plate decoration, particularly relates to the heater of automobile door plate decoration mold runner, belongs to the mould of plastics field.
Background technology
Automobile door plate is generally by door-plate body, each decoration, and the motor, glass-frame riser etc. that are installed in behind audio amplifier of door-plate, switch door are formed.Audio amplifier has bellmouth orifice, and the quality that bellmouth orifice is done is related to the class of a car and the percent of pass that audio amplifier sends audio frequency.Because bellmouth orifice position dense distribution a large amount of perforation of bumping, materials flow is subjected to the obstruction in these holes during injection moulding, flowing velocity can be affected, the heat that arrives this position materials flow scatters and disappears many, temperature also can be fallen than very fast, product is easy to take place the injection moulding deficiency during injection moulding, produces problems such as weld mark, epitome.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of materials flow temperature stabilization is provided, good fluidity, both made at the bellmouth orifice dense part and also can be filled with mould cavity, avoid injection moulding not in place, product produces the heater of the automobile door plate decoration mold runner of defectives such as weld mark, epitome.
The technical scheme of the heater of the utility model automobile door plate decoration mold runner is: comprise fixed clamping plate and moving clamping plate, be equipped with the cast gate locating ring in the fixed clamping plate, fixed clamping plate connects cover half through the hot flow path fixed head, nozzle is installed in the cover half, between fixed clamping plate and the cover half hot runner rack is installed, hot flow path in the hot runner rack is communicated with nozzle, ejecting mechanism is installed on the moving clamping plate, moving clamping plate connects dynamic model through the mould pin, gap between dynamic model and the cover half forms die cavity, the shower nozzle of nozzle is characterized in that in the described hot runner rack heating plate being installed facing to die cavity, and described nozzle twines heating collar outward.
The heater of automobile door plate decoration mold runner of the present utility model, heating plate and heating collar have been installed respectively outside described hot runner rack and nozzle, after materials flow enters mould from the plastics machine during injection moulding, continue to be heated plate and heating collar heating at hot runner rack and nozzle place, keep the hot melt state, enter the product die cavity with higher temperature and flowability by cast gate, because materials flow temperature height, good fluidity had both made at the bellmouth orifice dense part also can be filled with mould cavity, avoid injection moulding not in place, do not had the generation of defectives such as weld mark, epitome.
Description of drawings
Fig. 1 is the heater structural representation of the utility model automobile door plate decoration mold runner.
The specific embodiment
The utility model relates to a kind of heater of automobile door plate decoration mold runner, as shown in Figure 1, comprise fixed clamping plate 2 and moving clamping plate 15, be equipped with cast gate locating ring 1 in the fixed clamping plate 2, fixed clamping plate 2 connects cover half 5 through hot flow path fixed head 4, nozzle 16 is installed in the cover half, hot runner rack 3 is installed between fixed clamping plate 2 and the cover half 5, hot flow path in the hot runner rack 3 is communicated with nozzle 16, on the moving clamping plate 15 ejecting mechanism is installed, described ejecting mechanism comprises the push pedal 151 that is installed on the moving clamping plate 15, push rod fixed head 152 is installed in the push pedal, push rod 153 and oblique slide bar 154 are installed on the push rod fixed head 152, push rod 153 passes dynamic model 8, moving clamping plate 15 connects dynamic model 8 through mould pin 12, gap between dynamic model 8 and the cover half 5 forms die cavity 17, the shower nozzle 18 of nozzle 16 is facing to die cavity 17, it is characterized in that installing in the described hot runner rack 3 heating plate 20, described nozzle 16 outer heating collar 21. this programme that twine have been installed heating plate and heating collar respectively outside described hot runner rack and nozzle, after materials flow enters mould from the plastics machine during injection moulding, continue to be heated plate and heating collar heating at hot runner rack and nozzle place, keep the hot melt state, enter the product die cavity with higher temperature and flowability by cast gate, because materials flow temperature height, good fluidity had both made at the bellmouth orifice dense part also can be filled with mould cavity, avoided the injection moulding deficiency, the weldless trace, the generation of defectives such as epitome.
