Abstract
The utility model relates to a conveniently processed hot runner nozzle mechanism installed on a manifold and comprising a nozzle body, a heating coil, an insulation sleeve, a nozzle core and a sprue sleeve; the center of the nozzle body is provided with the hot runner; the nozzle core is disposed at the front end of the nozzle body; the heating coil is located at the outboard of the nozzle body and at the outboard of the heating coil is installed the insulation sleeve; at the front end of the nozzle core and the insulation sleeve as well as at the inboard of the nozzle body is arranged the sprue sleeve; the nozzle body is of a divide-body design and consists of two parts: the nozzle body is internally installed in the hot runner and an installing sleeve is sleeved at the outboard of the nozzle body and at the same time internally sleeved to the insulation sleeve. The nozzle mechanism introduced hereby adopts a structure in which the nozzle body and the installing sleeve thereof are separated. Arranged in this manner, the nozzle body and the installing sleeve of the nozzle body are processed independently. Since the inboard of the installing sleeve of the nozzle body has a greater space, the difficulty and the costs with processing the hot nozzle is greatly reduced. When well processed, the nozzle body and the installing sleeve of the nozzle body are directly put into a close-fitting joint before being sleeved to the insulation sleeve.
Description
Technical field
The utility model relates to a kind of hot mouth technical field of hot flow path, refers in particular to the hot mouth structure of the hot flow path of being convenient to process here.
Background technology
Hot flow path is the plastics maintenance molten condition that guarantees runner and cast gate by the way of heating.Since near runner or the center be provided with heating rod and heating collar; whole runner from the injection machine jet expansion to cast gate all is in the condition of high temperature; make the plastics in the runner keep fusion; do not need to open runner after the shutdown and take out material with fixed attention; only need add hot flow path when starting shooting again to temperature required getting final product; hot flow path is a general name, and hot mouth is the part of hot flow path.
TOP-TIP can save material, and reduces cost, shortens molding cycle, raises the efficiency; Improve products surface quality and mechanical property; The moulding uniform quality of multi-cavity mold; Improve injection-molded item surface aesthetic degree.
In general, TOP-TIP is divided into single head TOP-TIP, bull TOP-TIP and valve gate TOP-TIP.TOP-TIP mainly is made up of hot mouth, nozzle flow distribution plate, temperature control system etc.Hot mouth comprises mouth body, heating collar, collet, mouth core and sprue bush, at present, the mouth body rear end on the market is provided with boss, is provided with the mounting groove that collet is installed on boss, mouth body center is provided with the water conservancy diversion sleeve pipe, in process of production, the space is less between mounting groove and the water conservancy diversion sleeve pipe, in process, be not easy to process with universal cutter, adopt other processing method, its cost of processing is higher, and difficulty of processing is higher.
The utility model content
The utility model provides a kind of hot mouth structure of the hot flow path of being convenient to process at the prior art deficiency.
The hot mouth structure of the hot flow path that the utility model provides, hot mouth is installed on the flow distribution plate, hot mouth comprises mouth body, heating collar, collet, mouth core and sprue bush, mouth body center is provided with heat passage, and the mouth core is installed in mouth body front end, and heating collar is located at the external side of mouth, the outside at heating collar is equipped with collet, front end, collet and mouth body inner side at the mouth core are equipped with sprue bush, and described mouth body is a split-type structural, and it comprises two parts: in establish the mouth body of heat passage; Be sleeved on the outer end of mouth body, the mouth body installation sleeve of also interior socket collet.
Have slotted eye on the described mouth body installation sleeve, the slotted eye correspondence position of mouth body and mouth body installation sleeve is provided with the temperature inductor installing hole, is provided with temperature inductor in installing hole.
Described mouth body rear end is provided with boss, and the boss hole that matches with the boss of mouth body is established in the rear end on mouth body installation sleeve, is provided with the collet interface slot in mouth body installation sleeve front end inboard, is connected in the interface slot in the collet.
Adopt close-fitting to be connected between described mouth body and the mouth body installation sleeve, be provided with the screw thread that is spirally connected that cooperatively interacts between mouth body installation sleeve and the collet.
The beneficial effects of the utility model are: this structure mouth body, adopt mouth body and mouth body installation sleeve separate type, add man-hour, mouth body and mouth body installation sleeve are processed respectively, because the space of mouth body installation sleeve inboard is bigger, it is very easy to add man-hour, after processing, directly adopt close-fitting to be connected mouth body and mouth body installation sleeve, collet is installed on the mouth body installation sleeve again and gets final product.Always make hot mouth difficulty of processing significantly reduce, processing cost is lower.In addition, be provided with slotted eye and temperature inductor installing hole, temperature inductor can be set in installing hole, can more accurately carry out temperature control at mouth body installation sleeve and mouth body.
Description of drawings:
Fig. 1 is a structure chart of the present utility model
Fig. 2 is the utility model mouth main body structure figure
Fig. 3 is the structure chart of the utility model mouth body installation sleeve
The specific embodiment:
Only be the utility model preferred embodiment below, do not limit protection domain of the present utility model with this.
See shown in Figure 1, the hot mouth structure of the hot flow path that the utility model provides, hot mouth is installed on the flow distribution plate (not marking among the figure), hot mouth comprises mouth body, heating collar 2, collet 3, mouth core 4 and sprue bush 5, be provided with heat passage 11 in the mouth body in the heart, mouth core 4 is installed in mouth body front end, and heating collar 2 is located at the external side of mouth, for the mouth body provides heating; In the outside of heating collar 2 collet 3 is installed, mouth core 4 is provided with pod apertures, at front end, collet 3 and the mouth body inner side of mouth core 4 sprue bush 5 is installed, and sprue bush 5 is provided with the sprue gate, described mouth body is made of two parts, in establish the mouth body 1 of heat passage; Be sleeved on the outer end of mouth body 1, the mouth body installation sleeve 6 of also interior socket collet 3.
Described mouth body 1 rear end is provided with boss 12, and the boss hole that matches with the boss 12 of mouth body 1 is established in the rear end on mouth body installation sleeve 6, is provided with the collet interface slot in mouth body installation sleeve 6 front end inboards, is connected in the interface slot in the collet 3.Adopt close-fitting to be connected between described mouth body 1 and the mouth body installation sleeve 6.Be connected in the interface slot in the collet 3, be provided with the screw thread that is spirally connected that cooperatively interacts between mouth body installation sleeve 6 and the collet 3.So just can conveniently mouth body 1, mouth body installation sleeve 6 and collet 3 be installed together.
