The invention mainly provides a static mixer and an injection molding machine with the static mixer, and further provides a manufacturing method of the static mixer. The static mixer can mix the fluid, and improves the fluid mixing effect. When the static mixer is applied to the injection molding machine, the static mixer is arranged in a nozzle of the injection molding machine, and the plastic melt entering the nozzle is mixed to obtain more uniform fluid.
The illustration of the embodiment of the injection molding machine is omitted, and the following description will mainly describe the static mixer in detail with reference to the structural drawings of the static mixer, and reference may be made to the related art regarding the mounting and matching of the static mixer and the nozzle.
Referring to fig. 1 to 5, the static mixer 1 of the present embodiment includes an outer sleeve 11 and a mixing body inner core 12 fixed inside the outer sleeve 11.
The outer sleeve 11 is substantially cylindrical and its outer configuration can be adapted according to the configuration to which it is to be fitted. For example, when outer sleeve 11 is used to fit into a nozzle (not shown), outer sleeve 11 has a profile that matches the inner cavity of the nozzle. The outer surface of the outer sleeve 11 may be smooth or may be provided with structures such as threads, indentations, projections, etc. to address various installation circumstances.
The interior of the outer sleeve 11 is provided with a central hole 111 extending along the axis thereof and penetrating both ends of the outer sleeve 11, the central hole 111 forming an inlet 112 at one end face of the outer sleeve 11 and an outlet 113 at the other end face of the outer sleeve 11.
Preferably, the diameter D1 of the inlet 112 is slightly larger than the diameter D2 of the outlet 113. In some embodiments, the central hole 111 is in a circular truncated cone shape, that is, the diameter of the central hole 111 gradually decreases in the direction from the inlet 112 to the outlet 113, and the taper of the circular truncated cone shape may be between 1:300 and 1:500, which may be specifically adjusted according to the material shrinkage rate of the outer sleeve 11, the size of the outer sleeve 11, and the like. According to the different size of the inlet 112 and the outlet 113, when the fluid flows from the inlet 112 to the outlet 113 to generate pressure on the mixing body core 12, the outer sleeve 11 can bear the pressure to prevent the mixing body core 12 from moving towards the outlet 113, so as to better fix the mixing body core 12, thereby being suitable for the fluid with higher temperature and higher pressure.
Referring to fig. 2, 3 and 5, the inner core 12 is integrally formed as a single body, and includes a base 121 and a plurality of ribs 122 disposed on the outer periphery of the base 121. It is understood that the division of the matrix 121 and the ribs 122 is an artificial division based on the positional relationship thereof, and the matrix 121 and the ribs 122 are actually an integral, inseparable, monolithic structure.
The base 121 is provided with a central flow passage hole 1211 extending therethrough along an axis thereof, and the central flow passage hole 1211 is preferably circular in cross section.
Each rib 122 extends spirally around the axis of the base 121, and a spiral channel 123 extending spirally is formed between adjacent ribs 122. Namely: opposite surfaces of two adjacent ribs 122 form a spiral channel 123 extending spirally on the periphery of the base 121, and the surface of the rib 122 is also the wall surface of the spiral channel 123. Preferably, the spiral channel 123 has an arc-shaped normal cross-section, so that the flow lines are more uniform.
The number of ribs 122 is preferably more than three, and four ribs 122 are illustrated in the illustrated embodiment. The ribs 122 are evenly distributed around the axis of the base 121. In other embodiments, the number of ribs 122 may also be set according to the length of the mixing core 12, the outer dimensions, and the properties of the fluid.
Each rib 122 is provided with a first through hole 1221 penetrating through the adjacent spiral channel 123, and the base 121 is provided with a second through hole 1212 penetrating through the spiral channel 123 and the central runner hole 1211.
The first through holes 1221 and the second through holes 1212 may be arranged regularly, and distributed uniformly as much as possible. The total open area of the first through hole 1221 and the second through hole 1212 in each spiral channel 123 preferably accounts for 10% to 30% of the total surface area of the spiral channel 123.
The perforation directions of the first through hole 1221 and the second through hole 1212 are preferably perpendicular to the arc-shaped surface of the spiral channel 123, so as to reduce the flow resistance.
As shown in fig. 1 to 3, the mixing body inner core 12 is fixedly installed in the central hole 111 of the outer sleeve 11, and the outer surface of each rib 122 of the mixing body inner core 12 is attached and fixed to the inner wall of the central hole 111. Preferably, the outer sleeve 11 and the inner core 12 of the mixture are fixed in an interference fit mode, the joint surface is well attached, and a welding process is not needed.
According to the structural description of the static mixer 1, after the inner core 12 and the outer sleeve 11 are combined into a whole, the outer circumference of the spiral channel 123 of the inner core 12 is sealed by the inner wall of the outer sleeve 11, so that the spiral channel 123 surrounded by the outer sleeve 11 and the central flow passage 1211 of the inner core 12 form a closed fluid passage for fluid to flow, and the spiral channel 123 and the central flow passage 1211 are communicated through the first through hole 1221 and the second through hole 1212, so that the fluid is more favorably mixed when flowing in the fluid passage.
Specifically, when the fluid mass enters the static mixer 1 from the inlet 112 of the outer sleeve 11, the fluid mass is divided into a plurality of fluid streams at the inlet 112, and the fluid streams enter the central flow passage 1211 and the plurality of spiral passages 123 respectively. The fluid flow in one spiral channel 123 is broken by the boundary effect of the first through hole 1221 into a continuous fluid flow, and the original fluid flow will be partially separated into the adjacent spiral channels 123. The fluid flow in the central passage 1211 has a faster flow rate, and is compensated for pressure and flow with the spiral channel 123 under the communication effect of the second through hole 1212, so that the fluid flow in the spiral channel 123 is easily broken. The fluid mass is continuously separated and joined a plurality of times while flowing through the static mixer 1 from the inlet 112 to the outlet 113. The fluid mass forms strong turbulence at each separation and confluence point, so that each part of the fluid is quickly disturbed, the fluid mass generates vortex and shearing action due to pressure and flow change, the fluid tends to be more uniform, and finally the homogeneous fluid flows out from the outlet 113.
Compared with the existing SK type static mixer, the static mixer 1 of the scheme has obvious improvement on the fluid mixing effect.
Compared with the conventional SL-type static mixer, the fluid channel is formed by the central flow channel hole 1211 extending along the axis and the spiral channel 123 extending in a spiral shape in the scheme, the fluid channel is streamline on the whole in the flowing direction of the fluid, and dead angles vertical to the flowing direction and negative angles basically do not exist, so that the phenomenon that the flow speed of the local fluid is zero is avoided, the fluid is prevented from being retained, and the SL-type static mixer is more beneficial to subsequent cleaning and maintenance.
The static mixer 1 is mainly formed by fixing an integrally formed mixing body inner core 12 in an outer sleeve 11, has few parts, has a simpler structure compared with a conventional SL-type static mixer, and is convenient to manufacture. Through the structural style formed by assembling two parts, compared with the integral casting molding, the static mixer 1 does not need to adopt a precision casting process and a powder metallurgy technology during manufacturing, the processing cost is lower, and the mixing body inner core 12 can improve the smoothness of a fluid channel by finishing each surface, thereby improving the using effect.
In addition, the inner core 12 of the mixture can adopt a twisting process to form a spiral rib 122 structure, so that the machining of a triaxial and a quadcopter center with higher cost can be avoided, and the machining cost is reduced. The details will be described specifically with reference to the manufacturing method of the static mixer 1.
In the static mixer 1 of the present embodiment, the outer sleeve 11 and the inner core 12 of the mixture can be made of special alloy die steel or similar high-strength steel.
Referring to fig. 6 and 7, the present embodiment provides a method for manufacturing a static mixer 1, including:
s10: a central flow passage 1211 and a plurality of channel holes 1230 are formed on the periphery of a cylindrical blank 1000, forming a base 121 and a plurality of straight ribs 1220 distributed on the periphery of the base 121. In this process, the blank 1000 may be pre-processed, and then the central channel 1211 and the channel 1230 may be roughly processed by turning, milling, drilling, and the like, and then further processed by stress relief annealing, twisting, milling, and the like, and then semi-finished.
S20: the straight ribs 1220 are twisted by twist forming into the ribs 122 extending in a spiral shape, and the passage holes 1230 correspondingly form the spiral passages 123. This process twists the entire structure of the previous step, so that the straight ribs 1220, which originally extend along straight lines, form a spirally extending structure, and can be destressed by heat treatment before and after the twisting process.
S30: the first through holes 1221 are processed on the ribs 122, and the second through holes 1212 are processed on the substrate 121 to form the inner core 12 of the hybrid body. In this process, the first and second through holes 1221 and 1212 are formed by a drilling and reaming process, and further, a final mixed core 12 may be formed by a vacuum heat treatment, a finishing process, a surface treatment, or the like.
S40: the mixing body inner core 12 is put into the formed outer sleeve 11 and fixed. In this process, the two are integrated by an assembly process, i.e., the static mixer 1 is formed. Wherein, the forming process of the outer sleeve 11 can be processed according to actual conditions.
Preferably, in step S40, the mixed core 12 is cooled and then placed into the outer sleeve 11, and the mixed core 12 is fixed to the outer sleeve 11 in an interference fit after the temperature of the mixed core is recovered. Specifically, when the outer sleeve 11 is formed, the inner diameter of the middle hole 111 of the outer sleeve 11 is slightly smaller than the outer diameter of the inner core 12, the inner core 12 is cooled to a temperature below-50 ℃ by using low-temperature media such as liquid nitrogen, the inner core 12 is slightly reduced in size under the action of thermal expansion and cold contraction, and therefore the inner core can be installed into the outer sleeve 11, and after the temperature of the inner core 12 is restored, the size of the inner core 12 is increased to form interference fit with the outer sleeve 11 and fixed. And the structure condition of the mixed body inner core 12 can be changed through a cold-charging process, the mechanical property and the durability of the mixed body inner core 12 are favorably improved, and the application range and the use effect of the static mixer 1 are improved.
For the case where the inlet 112 of the central bore 111 is larger than the outlet 113, the mixing body core 12 is preferably disposed from the inlet 112 end into the outer sleeve 11.
In this manufacturing method of the present embodiment, the outer sleeve 11 can be formed by rough machining, semi-finishing, heat treatment, finishing, and surface treatment. These procedures can be carried out on conventional equipment. The above-mentioned rough machining, semi-finishing, heat treatment, finishing and surface treatment of the inner core 12 can be accomplished by common equipments.
Particularly low, after the inner core 12 of the mixture adopts the twisting process, the machining of a three-axis machining center and a four-axis machining center with higher cost can be avoided, meanwhile, the internal structural performance of the material can be more ideal by adopting a heat treatment means after the twisting process, and the obtained product has excellent mechanical performance.
In summary, compared with the welding forming or the metallurgy integral casting forming of a plurality of parts, the manufacturing method of the scheme can have less manufacturing cost and maintenance cost.
While the present invention has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
