Description
Technical field
The present invention relates to the flow passage system of plastics or other raw material processing, the equidistant hot-runner nozzle position adjustment structure of particularly a kind of multiple spot and method of adjustment and application.
Background technology
TOP-TIP is the extension of injection machine nozzle, some mainly as mould, the function of TOP-TIP is, in the plastics forming process, make plastics remain on molten condition always, while to different die cavitys, is exempted the waste of mouth of a river material to the molten state plastic guide, helps reducing injection pressure simultaneously, shorten injection cycle, improve the quality of products.
Existing TOP-TIP structure as shown in Figure 1, mainly comprise main charging aperture 101, runner plate 102, nozzle 103 3 parts, main charging aperture is connected with the injection hole of injection machine, main charging aperture is connected with the charging aperture of runner plate simultaneously, in runner plate, be provided with the distribution runner, the discharging opening of each runner that distributes is connected with each nozzle respectively, at main charging aperture, on runner plate and the nozzle heating component is installed, this TOP-TIP is installed in the template of mould, and circular central location 104 and alignment pin 105 positions of fixed flow guidance tape in template are equipped with in runner plate bottom centre.Need at different moulds, can change the quantity of the runner plate and the nozzle of different structure, to cooperate the instructions for use of different moulds.But existing this TOP-TIP structure all is the fixed arrangement form that is designed to, and runner plate designs according to the position of nozzle, and after the position of nozzle was determined, discharging opening corresponding in the runner plate can not be changed through machine-shaping; When the mould life cycle finishes, the TOP-TIP of this fixed structure can not be used on the mould that other different spray nozzles arranges.On the other hand, the client customizes the hot flow path of this fixed structure to hot flow path manufacturer, when nozzle location once determining, just can't change adjustment.As the design that runs into the later stage needs to change, and the fixed nozzle position that the mould design must be yielded to hot flow path can't make the mould design optimization, just otherwise runner plate need to reform, cause waste.
Application number is that 200910041198.7 Chinese invention patent discloses a kind of " hot-runner nozzle position adjustment structure and method of adjustment thereof and application ", this hot-runner nozzle position adjustment structure mainly comprises main charging aperture, runner plate, nozzle, runner plate and nozzle all are provided with charging aperture and discharging opening separately, also comprise the rotation transition block, described rotation transition block is provided with charging aperture and discharging opening, the axis of symmetry of charging and discharging mouth parallels setting, and two axis of symmetry are at a distance of certain distance (X); The charging aperture of described rotation transition block rotatably seals with the discharging opening of runner plate and docks, and the discharging opening of described rotation transition block rotatably seals with the charging aperture of nozzle and docks; The charging aperture of the nozzle assembly that described nozzle or nozzle and nozzle extension block are combined and the axis of symmetry of discharging opening also be arranged in parallel, and two axis of symmetry are at a distance of certain distance (Y).This hot-runner nozzle position adjustment structure can realize that nozzle location adjusts flexibly, and easy to use, applicability is good; But still have certain deficiency: the rotation transition block need be set specially, and its structure and annexation are all complicated a little, need to increase bigger manufacturing cost; In addition, in actual applications, being suitable for more structure is the equidistant hot flow path of multiple spot, the equidistant hot flow path of described multiple spot is meant that each nozzle of system is consistent with the distance of runner plate master charging aperture, and the equidistant hot flow path of this multiple spot is only need still keep multiple spot to get final product with the characteristic of distance by the nozzle location of system after adjustment to the requirement of adjusting; Though above-mentioned hot-runner nozzle position adjustment structure also can be used for the equidistant hot flow path of this multiple spot; But, because the position range that the equidistant hot flow path of this multiple spot need be adjusted is also little, a kind of structure is more simple, manufacturing cost is lower, practicality can be applicable to better that better the hot-runner nozzle position adjustment structure of the equidistant hot flow path adjustment of this multiple spot has even more important realistic meaning so design.
Summary of the invention
The shortcoming that the objective of the invention is to overcome prior art provides a kind of nozzle location to adjust flexibly with not enough, and simple in structure, manufacturing cost is relatively low, the equidistant hot-runner nozzle position adjustment structure of the multiple spot that Practical Performance is good.
Another object of the present invention is to provide a kind of equidistant hot-runner nozzle location regulation method of multiple spot that utilizes the equidistant hot-runner nozzle position adjustment structure of above-mentioned multiple spot to realize.
Still a further object of the present invention is to provide the application of equidistant hot-runner nozzle position adjustment structure of above-mentioned multiple spot and method of adjustment thereof.
