Abstract
The utility model discloses a spraying nozzle with a filter used for an injection mold hot runner system, which comprises a cylindrical spraying nozzle body which is provided with a feeding port and a discharging port. The feeding port or the discharging port is provided with a filter, the filter is a cylindrical column body, a feeding chute and a discharging chute which are parallel to the column body axially are arranged on the circumference surface of the column body, the feeding chute and the discharging chute are arranged at intervals, the top end of the feeding chute penetrates through the top surface of the column body, the bottom end of the feeding chute is not communicated with the bottom surface of the column body, the top end of the discharging chute is not communicated with the top surface of the column body, the bottom end of the discharging chute is communicated with the bottom surface of the column body, and a plurality of transverse material flowing chutes are arranged between the adjacent feeding chute and discharging chute. According to the spraying nozzle with the filter used for the injection mold hot runner system, the filter is arranged on the feeding port of the spraying nozzle body, unmelted plastic particles or impurities are blocked by the filter and cannot enter a mold, and the quality of injection products is guaranteed.
Description
Technical field
The utility model relates to a kind of injection mold hot runner system, relates to the nozzle that falls contaminant filter function that has in a kind of injection mold hot runner system specifically, comprises injection machine nozzle and hot flow path main burner.
Background technology
Compare with traditional cold runner injection mould system, the HOT RUNNER INJECTION MOULD system has advantages such as economizing in raw materials, enhances productivity and is extensively adopted, and nozzle is the critical piece in the HOT RUNNER INJECTION MOULD system.The nozzle that the injection mold hot runner system uses comprises injection machine nozzle and hot flow path main burner (being called hot flow path master cast gate again); Nozzle in the existing HOT RUNNER INJECTION MOULD system mainly is made up of a cylindric nozzle body with charging aperture and discharging opening; Usually the outer surface at nozzle body is provided with heater coil or cartridge heater, makes the injection molding material of the nozzle of flowing through keep temperature and flowability.But; Injection molding material in the process of heat fused, may the partly plastic particle fully fusing back just get into nozzle in company with the injection molding material of fusing, simultaneously; Also might partial impurities sneak in the injection molding material; If a unfused plastics material and impurity inject mould, can cause the decline of injecting products quality, even possibly cause waste product.
The utility model content
For overcoming above-mentioned defective, the utility model aims to provide a kind of filtering function that has, and the injection mold hot runner system that avoids a unfused plastics material or impurity to inject mould uses the nozzle with contaminant filter function.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of injection mold hot runner system comprises a cylindric nozzle body with charging aperture and discharging opening with the nozzle of band filter, has a filter in said charging aperture or the discharging opening.
Said filter is a cylindrical column; Have feed well and blow tank with the cylinder axially parallel on the periphery of said cylinder, said feed well and blow tank are spaced apart, and the top of said feed well runs through the end face of cylinder; The bottom of said feed well and the bottom surface of cylinder do not connect; The top of said blow tank and the end face of cylinder do not connect, and the bottom of said blow tank runs through the bottom surface of cylinder, have some horizontal chutes between said adjacent feed well and the blow tank.
Adopted the nozzle of the injection mold hot runner system of the utility model with the band filter; Owing in the charging aperture of nozzle body or discharging opening, be provided with filter; Make unfused plastics material or impurity be filtered device and block and can not get into mould, guaranteed the quality of injecting products.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the perspective view of the filter of the utility model;
Fig. 3 is the perspective view of the utility model;
Fig. 4 is a kind of example structure sketch map of the utility model;
Fig. 5 is a kind of embodiment perspective view of the utility model.
Among the figure: 1-nozzle body, 2-charging aperture, 3-discharging opening, 4-filter, 5-cylinder, 6-feed well, 7-blow tank, 8-chute.
The specific embodiment
As shown in figures 1 and 3; The utility model discloses the nozzle of a kind of injection mold hot runner system with the band filter; It comprises a cylindric nozzle body 1 with charging aperture 2 and discharging opening 3, and its innovative point mainly is to have a filter 4 in said charging aperture 2 or the discharging opening 3.The nozzle that embodiment as shown in figures 1 and 3 refers to mainly refers to the nozzle of injection machine, at this moment, is placed on filter 4 in the charging aperture 2 of nozzle body 1 usually, has a filtration tank that is complementary with filter 4 shape sizes in the said charging aperture 2.When injection molding material during through the nozzle of injection machine, need earlier through the filtration of the filter 4 on its charging aperture 2, filter 4 can fall a unfused plastics material or contaminant filter.
As shown in Figure 2; The injection mold hot runner system of the utility model is generally a cylindrical column 5 with used filter 4 in the nozzle of band filter; Have feed well 6 and blow tank 7 on the periphery of said cylinder 5 with cylinder 5 axially parallels; Said feed well 6 is spaced apart with blow tank 7, and the top of said feed well 6 runs through the end face of cylinder 5, and the bottom surface of the bottom of said feed well 6 and cylinder 5 does not connect; The end face of the top of said blow tank 7 and cylinder 5 does not connect; The bottom of said blow tank 7 runs through the bottom surface of cylinder 5, has some horizontal chutes 8 between said adjacent feed well 6 and the blow tank 7, and the width dimensions of chute 8 is less usually.When injection molding material is flowed through filter 4; Can be introduced into feed well 6; Because the bottom of feed well 6 and the bottom surface of cylinder 5 do not connect; So injection molding material can only laterally flow into blow tank 7 through chute 8, from bottom flow nozzle body 1 inner chamber of blow tank 7, finally flow out and inject mould again from discharging opening 3.When injection molding material was flowed through chute 8, a unfused plastics material or impurity were blocked, and have guaranteed the quality of injecting products.
The nozzle that refers to like Fig. 4 and embodiment shown in Figure 5 mainly refers to the TOP-TIP main burner, at this moment, is placed on filter 4 in the discharging opening 3 of nozzle body 1 usually, has a filtration tank that is complementary with filter 4 shape sizes in the said discharging opening 3.When injection molding material during through the main burner of TOP-TIP, before ejection, can need filtration through the filter 4 that is provided with on its discharging opening 3, filter 4 can fall a unfused plastics material or contaminant filter.
