Abstract
The utility model relates to a thermostatic type injection molding material wound packages is put, including the feed cylinder body, screw rod and heating collar, its characterized in that: the feed cylinder body go up segmentation seal installation and have the feed cylinder cover, each feed cylinder is sheathe in and is provided with the heating collar, the feed cylinder is internal to be provided with a plurality of independent runners mutually, the exit of each runner are located the feed cylinder sheathes in, imports and exports and is provided with respectively into the valve and go out the valve, is provided with a thermocouple on the feed cylinder body that every section feed cylinder cover corresponds. The utility model discloses can avoid plastics melting in -process to produce the phenomenon of decomposing or turning to be yellow, promote plastic products shaping quality and precision.
Description
Technical field
The utility model relates to a kind of thermostatic type injection molding material cartridge, is mainly used in the quality of the injection mo(u)lding ensureing thermally sensitive special plastics or precise plastic product, reduces the disqualification rate of injection mo(u)lding.
Background technology
Existing domestic injection machine majority of case is to the just simple heating of the temperature of barrel, plastics are inner at barrel, transition process from solid to molten condition, a thermocouple of every section of upper only configuration, therefore certain point can only be controlled, and made each section of temperature remain on the temperature of melting needs by Fuzzy Processing, but certain between control point a bit may be higher, thus plastics produce at melting process and decompose or the phenomenon of jaundice, thus affect the performance of machine and the quality of plastic products and formed precision.
Utility model content
Technical problem to be solved in the utility model overcomes deficiency of the prior art and provides a kind of can avoiding to produce the phenomenon of decomposing or turning to be yellow in plastics melting process, promotes the thermostatic type injection molding material cartridge of plastic product forming quality and precision.
The technical scheme in the invention for solving the above technical problem is: this thermostatic type injection molding material cartridge, comprise barrel body, screw rod and heating collar, it is characterized in that: on described barrel body, segmented seal is provided with barrel cover, each barrel puts and is provided with heating collar, multiple mutual independently runner is provided with in barrel body, the import and export of each runner are positioned at barrel and put, and import and export and are respectively arranged with into valve and go out valve, and the barrel body of every section of barrel cover correspondence is provided with a thermocouple.
Barrel body described in the utility model is provided with three sections of mutual independently runners according to homogenizing zone, compression section and feeding section.
The utility model compared with prior art has the following advantages: the utility model operationally, according to the characteristic of plastics, to the needs of control temperature, corresponding fluid (or water) is added from entering valve, make to be full of fluid (or water) in each section of runner, close into and out of valve, heating collar work and due to plasticizing time screw rod drive plastics produce shear heat make plastic heating, under the effect of fluid (or water), after temperature reaches certain value, plastics temperature will no longer rise, thus be reached through fluid (or water) and control every section of temperature.The utility model is by carrying out thermostatic control to each section of plasticizing process, make full use of fluid (or water) flowing and temperature be no more than the physical characteristics such as boiling point, can accomplish control temperature and actual temperature deviation little, even if thermocouple is malfunctioning cause continuous heating, the plastics or yellowing phenomenon that make melting process because temperature is too high can not be caused, thus guarantee the Forming Quality of plastic products.Effectively to solve in existing injection moulding production process the defects such as goods jaundice, decomposition, improve quality and the precision of plastic products, especially wherein the stability of the special machine of the special material such as precise injection machine and PVC, accurate performance improve all greatly to make injection machine.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A-A of Fig. 1 is to schematic cross-section.
Detailed description of the invention
See Fig. 1-Fig. 2, the utility model comprises into valve 1, goes out valve 2, thermocouple 3, barrel body 4, fluid (water) 5, barrel cover 6, heating collar 7, screw rod 8.
Barrel body 4 is provided with three sections of mutual independently runners according to homogenizing zone, compression section and feeding section, barrel cover 6 is also divided into three sections to be arranged on barrel body 4 respectively by section, should be noted the sealing between barrel cover 6 and barrel body 4, avoiding there is leakage phenomenon when adding fluid.The import and export of each runner lay respectively on corresponding barrel cover 6, and are respectively arranged with into valve 1 in import and export and go out valve 2, and the barrel body 4 that every section of barrel overlaps 6 correspondences is provided with a thermocouple 3.Each barrel cover 6 installs heating collar 7.
During work, close out valve 2, fluid (or water) 5 selected by plastics according to processing, enter from the valve 1 that enters of each runner, close into valve 1 after making to be full of fluid (or water) 5 in runner, heating collar 7 works, be heated to plastics plasticizing temperature required, and by thermocouple 3, temperature feedback is controlled to control system temperature, then plastified by motor-driven screw 8, finally by oil cylinder pushing screw rod 8, molten plastic is injected in injection mold by charging barrel spray nozzle sub-assembly.
In addition, it should be noted that, the specific embodiment described in this description, the shape, institute's title of being named etc. of its parts and components can be different.All equivalences of doing according to structure, feature and the principle described in the utility model inventional idea or simple change, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
