Abstract
The utility model discloses a kind of injection machine colloidal sol back pressure mechanism, the screw rod comprising colloidal sol cylinder and match with colloidal sol cylinder, screw rod is connected with screw rod power set, it is characterized in that: also comprise control device, and control device is electrically connected with screw rod power set; Be provided with storing counterbalance valve, storing back pressure in described colloidal sol cylinder than row valve and control valve, and be provided with pressure sensor in colloidal sol cylinder, storing counterbalance valve, storing back pressure are than row valve and pressure sensor electrical connection control device.The utility model controls storing back pressure, plays pressure time shorten, plays pressure stroke and shortens, do miscellaneous goods better effects if especially, ensure product quality for large screw rod.
Description
Technical field
The utility model belongs to injection machine field, specifically, relates to a kind of injection machine colloidal sol back pressure mechanism.
Background technology
The material melts of injection machine is realized by rubber melting cylinder assembly.General injection machine smelting glue back pressure Problems existing:
1, when general injection machine smelting glue back pressure plays pressure, the time is longer. and when the back pressure for medium-and-large-sized injection machine melten gel plays pressure, the time is 5--10 second.
2, when general injection machine smelting glue back pressure plays pressure, the stroke of melten gel is longer, and the stroke for medium-and-large-sized injection machine melten gel is that 80MM-120MM just plays pressure.
When producing miscellaneous goods for client with large type injection machine especially, melten gel stroke completes, and smelting glue back pressure does not also play pressure or also do not reach the back pressure of melten gel setting, cause sizing material no compression like this, the product produced is loose, and product quality does not pass a test, or even scraps.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned defect, provide a kind of reasonable in design, result of use good and can ensure the injection machine colloidal sol back pressure mechanism of product quality.
For solving the problem, the technical scheme that the utility model adopts is:
A kind of injection machine colloidal sol back pressure mechanism, the screw rod comprising colloidal sol cylinder and match with colloidal sol cylinder, screw rod is connected with screw rod power set, it is characterized in that: also comprise control device, and control device is electrically connected with screw rod power set; Be provided with storing counterbalance valve, storing back pressure in described colloidal sol cylinder than row valve and control valve, and be provided with pressure sensor in colloidal sol cylinder, storing counterbalance valve, storing back pressure are than row valve and pressure sensor electrical connection control device.
Described control device comprises controller, and controller is electrically connected with server and display, and controller electrical connection screw rod power set, storing counterbalance valve, storing back pressure are than row valve and pressure sensor.
Described screw rod power set are the stepper motor be connected with screw drive.
Single-chip microcomputer and peripheral circuit thereof is provided with in described controller.
Owing to have employed technique scheme, compared with prior art, the utility model controls storing back pressure, plays pressure time shorten, plays pressure stroke and shortens, do miscellaneous goods better effects if especially, ensure product quality for large screw rod.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of a kind of embodiment of the utility model.
Detailed description of the invention
Embodiment:
As shown in Figure 1, a kind of injection machine colloidal sol back pressure mechanism, the screw rod 3 comprising colloidal sol cylinder 1 and match with colloidal sol cylinder 1, screw rod 3 is connected with screw rod power set, also comprises control device in addition, and control device is electrically connected with screw rod power set.Be provided with storing counterbalance valve 4 in described colloidal sol cylinder, storing back pressure than row valve 5 and control valve 6, and is provided with pressure sensor 2 in colloidal sol cylinder 1, storing counterbalance valve 4, storing back pressure are electrically connected control device than row valve 5 and pressure sensor 2.
In the present embodiment, described control device comprises controller, and controller is electrically connected with server and display, and controller electrical connection screw rod power set, storing counterbalance valve, storing back pressure are than row valve and pressure sensor.
Described screw rod power set are the stepper motor be connected with screw drive.Single-chip microcomputer and peripheral circuit thereof is provided with in described controller.
The utility model controls storing back pressure, plays pressure time shorten, plays pressure stroke and shortens, do miscellaneous goods better effects if especially, ensure product quality for large screw rod.
Above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit, although execute example with reference to previous examples to be described in detail the utility model, those of ordinary skill in the art is to be understood that, it is according to can modifying to the technical scheme that foregoing embodiments is recorded, or equivalent replacement is carried out to its portion of techniques feature, and these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the category of technical solutions of the utility model.
