Above-mentioned several injection mold hot nozzle, though all there is advantage separately, solved different technical problems, but there is a common shortcoming in these several injection molds with hot nozzle: be exactly this all class hot nozzles all be to be special the forming of a certain mould amount body, because of being subjected to the restriction of mould actual size, can only use on a certain specific mould, can not use on other mould, its versatility is not strong; When this class injection mold installs to hot nozzle on the hot flow path device, after the die trial,, in the time of need more changing gate location, must scrap existing hot nozzle if find that the glue gate location is undesirable, make new hot nozzle again.Will increase client and supplier's cost like this, and the time of having wasted both.
Summary of the invention
The technical problem that the utility model solves is to overcome above-mentioned shortcoming, provides a kind of to need removable parts parts, the injection mold hot nozzle that just can reuse.
The utility model can also be general with other mould.
In order to reach a removable parts parts, keep the parts of most of hot nozzle, just the hot nozzle that can reuse or general with other mould.The utility model has adopted following technical scheme: design a kind of injection mold hot nozzle, comprise heating tube and nozzle body, described nozzle body is made up of nozzle body canned paragraph and the nozzle body section of moving two parts, the nozzle body section of moving is enclosed within the centre bore of nozzle body canned paragraph, and can slide up and down along centre bore; Along the center line of the nozzle body section of moving one mesopore that runs through the nozzle body section of moving, the metal catheter that has an external diameter and its internal diameter to match are arranged in mesopore.
The section of moving heating tube is arranged on the outer wall of the nozzle body section of moving.
The described nozzle body section of moving is formed by moving section top and mobile pars infrasegmentalis, moves section top and mobile pars infrasegmentalis and flexibly connects, and metal catheter is positioned at the mesopore that moves section top.
On nozzle body canned paragraph center bore inner wall, locating slot is arranged, banking stop is arranged on the top of the nozzle body section of moving.
On the end face cushion block is being arranged on the nozzle body section of moving.
Described cushion block is that two parts are formed, and wherein a part is fixing cushion block, and another part is replaceable cushion block.
Fixedly on the cushion block seal groove is being arranged.
In the nozzle body section of moving lower end the sealing ring is arranged.
Between mobile section top and mobile pars infrasegmentalis, seal groove A is arranged.
Fixedly between cushion block and the metal catheter for being threaded.
The utility model is owing to adopted nozzle body to be made up of nozzle body canned paragraph and the nozzle body section of moving two parts, and the nozzle body section of moving is enclosed within the centre bore of nozzle body canned paragraph, and can slide up and down along centre bore; Along the center line of the nozzle body section of moving one mesopore that runs through the nozzle body section of moving is arranged, the structure of the metal catheter that an external diameter and its internal diameter match is arranged in mesopore.Like this, after die trial, find that the glue gate location is undesirable, when needing more swap-in glue gate location, on new gate location, when this hot nozzle is installed, after just only needing to change metal catheter, after the adjusting nozzle body section of moving is enclosed within the relative position of nozzle body canned paragraph, increase or reduce the thickness of replaceable cushion block, just can be used as new hot nozzle again and use; In addition, this nozzle also has and the general advantage of other mould.
