Abstract
The utility model provides a split type nozzle lining, which is formed by threaded coordination of a first nozzle lining and a second nozzle lining, wherein the end part at which the first nozzle lining and the second nozzle lining can be matched is provided with a first lug boss and a second lug boss; the threaded arrangement is arranged between the first lug boss and the second lug boss; the second nozzle lining is arranged correspondingly to a rubber sealing ring and a nozzle point, and the cavity shape of the second nozzle lining is matched with the shape of the rubber sealing ring and the nozzle point; and one of the first lug boss and the second lug boss is an outer lug boss, and the other one of the first lug boss and the second lug boss is an inner lug boss. With the adoption of the scheme provided by the utility model, the problems of low product pass rate and higher production cost because the conventional nozzle lining has large size machining error can be mainly solved.
Description
Technical field
The utility model belongs to TOP-TIP field, is related to a kind of Split hot nozzle bushing of TOP-TIP.
Background technology
Hot mouth is as the hot-runner component on injection moulding apparatus, and commonly using hot mouth includes hot mouth body, the hot mouth point with hot mouth body fits, and the sealing ring being arranged between hot mouth body and hot mouth point；Hot mouth bushing, conventional hot mouth bush structure are provided with the periphery of hot mouth body and hot mouth point as shown in figure 1, hot mouth bushing 1 is the monolithic construction of disposable machine-shaping, its internal shape and hot mouth main body and the sharp form fit of hot mouth.But it is due to the disposable machine-shaping of hot mouth bushing 1, because hot mouth body is longer, it is correspondingly arranged at the sealing glue position 2 between hot mouth body and hot mouth point at the position of sealing ring and deeper position is on hot mouth bushing 1, and for the generation of the phenomenons such as preventing from cementing leakage, the dimension precision requirement to sealing glue position 2 is higher.Hot mouth bushing in processing, it is necessary to by process tool stretch out it is long go to process sealing glue position, because cutter is longer, insufficient strength so that the scale error that sealing glue position is processed is larger, causes that the qualification rate of product is relatively low, percent defective is higher, and production cost is higher.
The content of the invention
The utility model is solves the above problems there is provided a kind of Split hot nozzle bushing, and it is larger that its purpose is mainly the existing hot mouth liner size mismachining tolerance of solution, causes the problem of product yield is relatively low, production cost is higher.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of Split hot nozzle bushing, is matched somebody with somebody by the first hot mouth bushing and the second hot mouth bush threads and is combined into；Wherein, the end that the first hot mouth bushing and the second hot mouth bushing are engaged is provided with first boss and second boss, and the screw thread is arranged between the first boss and second boss.
Relevant content in above-mentioned technical proposal is explained as follows：
1st, in such scheme, the second hot mouth bushing correspondence sealing ring and hot mouth point are set.
2nd, in such scheme, the form fit of the cavity shape of the second hot mouth bushing and the sealing ring and hot mouth point.
3rd, in such scheme, in both described first boss and second boss, one is outer lug boss, and another one is inner convex platform.Wherein, described " outer lug boss " refers to the boss set on the external diameter side face of the first hot mouth bushing or the second hot mouth bushing；" inner convex platform " refers to the boss set on the internal diameter side face of the first hot mouth bushing or the second hot mouth bushing.
Due to the utilization of the technical program, the utility model has following advantages compared with prior art：
1st, because hot mouth bushing is arranged to split type composition by the utility model, the sealing glue position high to dimension precision requirement is easy to first process, assembled after machining, then by two split parts, disposably processed its appearance and size, so at the higher position of accurate to dimension, cutter need not stretch out oversize, it is ensured that the intensity of cutter, so as to ensure to be processed the precision of size, the qualification rate of product is high, up to 100%.
2nd, the utility model is simple in construction, practicality, and easy to process, production cost is low.
Brief description of the drawings
Accompanying drawing 1 is prior art hot mouth bush structure schematic diagram；
The utility model structural representation of accompanying drawing 2.
In the figures above：1st, hot mouth bushing；2nd, sealing glue position；3rd, the first hot mouth bushing；4th, the second hot mouth bushing；5th, first boss；6th, second boss.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Embodiment：
As shown in Fig. 2 a kind of Split hot nozzle bushing, is matched somebody with somebody by the first hot mouth bushing 3 and the screw thread of the second hot mouth bushing 4 and is combined into；Wherein, the end that the first hot mouth bushing 3 and the second hot mouth bushing 4 are engaged is provided with first boss 5 and second boss 6, and the screw thread is arranged between the first boss 5 and second boss 6.
The corresponding sealing ring of the second hot mouth bushing 4 and hot mouth point are set.
The form fit of the cavity shape of the second hot mouth bushing 4 and the sealing ring and hot mouth point.
In both described first boss 5 and second boss 6, one is outer lug boss, and another one is inner convex platform.Wherein, described " outer lug boss " refers to the boss set on the external diameter side face of the first hot mouth bushing 3 or the second hot mouth bushing 4；" inner convex platform " refers to the boss set on the internal diameter side face of the first hot mouth bushing 3 or the second hot mouth bushing 4.
The Split hot nozzle bushing is made up of whole bushing two parts, so it is easy to ensure the machining accuracy to dimension precision requirement higher part position, after two parts size is all processed, two parts are combined again, disposably process its appearance and size, the qualification rate of product is ensure that, and production cost is relatively low.Split type processing not only saves material, reduces difficulty of processing, and assembles simpler, flexible, reaches purpose that is not only cost-effective but also improving production efficiency.
Above-described embodiment only to illustrate technical concept of the present utility model and feature, its object is to allow person skilled in the art to understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent change or modifications made according to the utility model Spirit Essence, should all cover within protection domain of the present utility model.
