Description
Technical Field
The utility model relates to a technical field of moulding plastics specifically is a bull colour changing hot nozzle hot runner device.
Background
With the continuous development of the injection molding industry, the requirements of plastic products in injection molding processing equipment are higher and higher, multi-cavity molds are more and more common in mold forming, the occupied proportion is increased year by year, and the utilization rate of various engineering plastics to hot runners is greatly increased; the strict requirement on the temperature of a hot nozzle, high abrasion of the hot nozzle and the like restrict the service life of a hot runner, the traditional side glue inlet hot nozzle for a high-cavity die is formed by extruding molten plastic in a runner main body from a nozzle body part through the runner main body and the nozzle body positioned at the tail end of the runner main body, injecting the molten plastic into a die cavity and forming the molten plastic into a product, wherein the form has the following defects: the increase of injection mold, the product ranks and reduces, and production efficiency reduces, and single-end hot mouth has certain limitation, consequently urgent needs a can thoroughly change the novel hot mouth of design in the past.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a bull trades look hot mouth hot runner device has solved the problem that proposes in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a bull is traded look hot nozzle hot runner device, includes that the heat is chewed the body, the body outside top embedding of heat is fixed with the casting formula and is sent out the heat coil, body bottom middle part bolted connection has the temperature sensing point is chewed to the heat.
As an alternative scheme of this application technical scheme, the sprue has been seted up at body top is chewed to the heat, sprue bottom both sides intercommunication has the subchannel.
As an alternative scheme of this application technical scheme, the discharge opening has been seted up to the subchannel bottom, the inside fixedly connected with of discharge opening chews the core.
As an optional scheme of the technical scheme, the bottom of the nozzle core is communicated with a hot nozzle shunt shuttle, and a hot nozzle sealing and pouring ring is clamped and fixed on the outer side of the hot nozzle shunt shuttle.
As an optional scheme of the technical scheme, an electric heating ring is embedded and fixed at the bottom of the outer side of the hot nozzle body.
Compared with the prior art, the beneficial effects of the utility model are as follows:
1. the utility model discloses a helicla flute casting formula heating methods, make full use of heat transfer, furthest reduces the heat loss, and the reduce power matches, makes hot mouth bulk temperature reach evenly.
