Abstract
The utility model relates to a bull mouth technical field just discloses a bull mouth, including bull mouth overcoat, the inside of bull mouth overcoat is equipped with bull mouth body, the bottom of bull mouth overcoat is equipped with bull mouth heart, the bottom of bull mouth heart is equipped with bull mouth tip, and four have constituted hot mouth of hot runner bull. This bull mouth seals the glue position through the modification, has increased the quantity of hot mouth tip, can produce more products simultaneously, has changed heat transfer device's material and has used, has reduced the risk that appears cold burden or block up out gluey mouthful.
Description
Technical Field
The utility model relates to a bull mouth technical field specifically is a bull mouth.
Background
The existing multi-head nozzle consists of a hot nozzle body, a body heating device, a splitter box and a nozzle tip. The sprue that the sizing material was seted up through hot chewing body flows to the splitter box runner, and the mouth point flows to again. Need install the body around the body and generate heat the device and guarantee that the sizing material can not solidify at the in-process that flows, the mouth point is installed in the splitter box bottom simultaneously, carries the sizing material for every mouth point through the splitter box, needs installation runner department around the mouth point to prevent that the mouth point from dropping, and the runner department is responsible for blocking the sizing material and flows to the hot runner duct simultaneously, and these have increased whole volumes, lead to putting down 2 or 3 mouth points on the same body only. And because the runner department executes the function of blocking glue, heat is dispersed and transmitted to the hot nozzle opening frame, so that glue is easy to solidify when flowing out, a glue outlet is blocked, and a fault that glue cannot be discharged occurs, therefore, the multi-head nozzle is provided.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
The utility model provides a be not enough to prior art, the utility model provides a bull mouth possesses and seals the glue position through the modification, has increased the quantity of hot mouth tip, can more products of coproduction, and the material that has changed the heat transfer device uses, has reduced the advantage that appears the cold burden or block up the risk of glue outlet, has solved the problem that proposes in the above-mentioned background art.
(II) technical scheme
The utility model provides a following technical scheme: the utility model provides a multi-head mouth, includes the bull mouth overcoat, the inside of bull mouth overcoat is equipped with the bull mouth body, the bottom of bull mouth overcoat is equipped with multi-head mouth heart, the bottom of multi-head mouth heart is equipped with the bull mouth tip, and four have constituted hot mouth of hot runner bull.
Furthermore, be equipped with screw counter bore and screw via hole on the bull mouth body, be equipped with the screw hole that is used for placing the screw on the bull mouth overcoat, pass through screwed connection between the two.
Furthermore, a heating wire is embedded on the multi-head nozzle body, and heat is transferred to the rubber material in the flow channel through the multi-head nozzle body.
Furthermore, a groove is formed in the center of the multi-head mouth, and the diameter of the groove is larger than that of the multi-head mouth body and used for limiting the left and right deviation of the hot mouth.
Compared with the prior art, the utility model provides a bull mouth possesses following beneficial effect:
this bull mouth through revising and glue the position, has increased the quantity of hot mouth nib, can produce more products simultaneously. The material use of the heat transfer device is changed, and the risk of cold materials or glue outlet blockage is reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1. a multi-head mouth outer sleeve; 2. a multi-tip nozzle body; 3. a multi-headed mouth core; 4. a plurality of nozzle tips.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1, a multi-head nozzle, including a multi-head nozzle jacket 1, a multi-head nozzle body 2 is arranged inside the multi-head nozzle jacket 1, a multi-head nozzle core 3 is arranged at the bottom of the multi-head nozzle jacket 1, a multi-head nozzle tip 4 is arranged at the bottom of the multi-head nozzle core 3, the four parts form a hot nozzle of a hot runner, a screw countersunk hole and a screw via hole are arranged on the multi-head nozzle body 2, a threaded hole for placing a screw is arranged on the multi-head nozzle jacket 1, the two are connected by a screw, a heating wire is embedded on the multi-head nozzle body 2, the multi-head nozzle body 2 is used for transferring heat for a sizing material in a flow channel, a groove is arranged on the multi-head nozzle core 3, the diameter of the groove is larger than the diameter of the multi-head nozzle body 2, and is used for limiting the left and right deviation of the hot nozzle.
Possess screw counter bore and screw via hole on the bull mouth body 2, possess the screw hole that is used for placing the screw on the bull mouth overcoat 1, two devices can pass through screwed connection. Meanwhile, the heating wire is embedded in the multi-nozzle body 2, and heat is transferred to the rubber material in the flow channel through the multi-nozzle body, so that the rubber material is prevented from being solidified. The multi-nozzle outer sleeve 1 is clamped in a notch formed in the hot nozzle of the mold to achieve the positioning effect, and then a flow distribution plate of a hot runner is placed above the multi-nozzle outer sleeve 1, so that the multi-nozzle outer sleeve 1 is fixed to achieve the effect of fixing the multi-nozzle body 2, and the up-and-down movement of the hot nozzle is limited.
The device is provided with a temperature transfer device, the temperature transfer device is responsible for receiving heat transferred by the multi-head nozzle body 2, when glue flows to the position, the glue cannot be solidified due to too much temperature reduction, the temperature transfer device is composed of a multi-head nozzle core 3 and a multi-head nozzle tip 4, the multi-head nozzle core 3 is made of titanium alloy, the multi-head nozzle core 3 is used for blocking the glue from flowing to a hot runner groove, the multi-head nozzle core 3 can be in contact with the opening frame in the process, the heat can be transferred to a die, the glue temperature is caused to be solidified and blocked due to too low temperature, the material is replaced by the titanium alloy, the titanium alloy cannot transfer too much heat, the multi-head nozzle tip 4 is made of tungsten steel, the tungsten steel can better transfer temperature, the multi-head nozzle core 3 made of the titanium alloy is used in the front, the value of the heat transferred to the multi-head nozzle tip 4 is very small, in order to transfer the temperature to the next stage better, the multi-head nozzle tip 4 is made of the tungsten steel with the better heat, and the two are combined together through a diffusion welding technology.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
