Description
Technical field
The utility model belongs to Hot runner Technology field, more particularly to a kind of new hot mouth pressure cap.
Background technology
Hot Runner System makes the injection of product possess higher quality in the injection moulding process of plastic product, hot just because of this
The structure type of flow passage system is also required to better prioritization scheme.In the application of Hot Runner System, hot mouth front end pressure cap passes through
Sealing is realized with cavity surface and face cooperation, and heat scatters and disappears in order to prevent, and contact surface is usually smaller.
There are many defects for the open pin-point gate structure of Hot Runner System at present.
The logical glue mode of prior art hot mouth runner as shown in Figure 1 is that sizing material passes through mouth body runner（a）It is directly entered nozzle point
Runner（b）, pass through branch flow passage in nozzle point flow field end（c）It carries out being further separated into sizing material flow model intracavitary（d）, pass through（e）Place
The cooperation of the face of pressure cap and cavity and face carrys out sealing, but heat scatters and disappears in order to prevent, and it is smaller to be generally mated face, for a long time injection pressure
Cap can be worn with cavity, so as to cause leak adhesive.
The content of the invention
It can be solved in view of the deficienciess of the prior art, technical problem to be solved in the utility model is to provide one kind
Certainly during Hot Runner System injecting products the problem of cast gate leak adhesive.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of new hot mouth pressure cap, including
Hot mouth body, the hot mouth body outer wall is cased with hot nozzle cannot heat device and limits the heater baffle ring that hot nozzle cannot heat device slides, described
Hot mouth body is equipped with hot mouth temp.-sensing wire, and the cavity of the hot mouth body is interior sharp-tongued equipped with hot mouth, and the hot mouth is sharp-tongued to pass through hot mouth
In in the cavity of hot mouth body, the hot mouth body is externally provided with mold with hot mouth pressure cap and opens frame, the hot mouth pressure cap screw-threaded coupling
Pressure cap front end is equipped with seal groove, is equipped with metal o-ring in the seal groove, the metal o-ring is located at seal groove
It is opened with mold between frame.
Above-mentioned new hot mouth pressure cap, the metal o-ring by hot mouth pressure cap and mold open frame between squeeze, it is described
Metal o-ring is deformed realizing secondary sealing.
The advantages of the utility model new hot mouth pressure cap is：
1st, the new hot mouth pressure cap of the utility model, hot mouth pressure cap and mold open the corresponding fitting completely of frame size, basic herein
Upper hot mouth pressure cap front end machined seal groove, and hot mouth pressure cap opens frame before by increasing seal groove and metal sealing with mold
Circle realizes secondary sealing, and hot mouth pressure cap opens frame size with mold during long-time service abrasion, in the case of losing sealing ability, still
So there is metal o-ring to realize that sealing is protected.
2nd, the new hot mouth pressure cap of the utility model, seal groove can be processed on the basis of existing hot mouth pressure cap, easy to process.
Metal o-ring can according to the size of different hot mouth pressure caps to adjust, this ring structure it is simple, easy for installation and have good
Stability.The service life of hot mouth pressure cap can further be extended.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment one, as shown in Figure 2,3, 4, a kind of new hot mouth pressure cap, including hot mouth body 1, outside the hot mouth body 1
Wall is cased with hot nozzle cannot heat device 4 and limits the heater baffle ring 8 that hot nozzle cannot heat device 4 slides, and contains in the hot nozzle cannot heat device 4 and adds
Heated filament and outer tube, the heater baffle ring 8 are installed on the matched face of hot mouth body 1, and the hot mouth body 1 is equipped with heat
Mouth temp.-sensing wire 5, the hot mouth temp.-sensing wire 5 are installed in the temperature-sensitive wire casing 10 of the hot mouth body 1, the chamber of the hot mouth body 1
Hot mouth sharp-tongued 2 is equipped in vivo, and plastic cement runner 9 is equipped in the hot mouth body 1, is equipped with and the plastic cement stream in institute's hot mouth sharp-tongued 2
The sharp-tongued runner 11 that road 9 is connected, the hot mouth sharp-tongued 2 by 3 screw-threaded coupling of hot mouth pressure cap in the cavity of hot mouth body 1,
The hot mouth body 1 is externally provided with mold with hot mouth pressure cap 3 and opens frame 7, and 3 front end of hot mouth pressure cap is equipped with seal groove 12, described
It is equipped with metal o-ring 6 in seal groove 12, the metal o-ring 6 is located at seal groove 12 and mold is opened between frame 7.It is described
Metal o-ring 6 by hot mouth pressure cap 3 and mold open frame 7 between squeeze, the metal o-ring 6 is deformed realizing secondary envelope
Glue.
In actual use, since hot nozzle cannot heat device heats hot mouth, hot mouth, which is heated, can expand, is elongated, heat
Spacing can reduce between mouth pressure cap and mold cavity, and metal o-ring extrusion is more advantageous to sealing.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the specific implementation of the utility model is not
It is limited by the above embodiment.Those skilled in the art can be on the premise of without departing from the utility model technical concept, to this
Various modification can be adapted or modification for utility model, these modifications or modification are also fallen within the scope of protection of the utility model certainly.
