Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the present invention provides a method for controlling injection molding and glue injection of a bottom case of a printer S10, for controlling injection molding and glue injection of an injection molding machine to manufacture a bottom case of a printer, the method for controlling injection molding and glue injection of a bottom case of a printer S10 includes:
step S11, detecting whether the mold is closed and whether sufficient sol exists in the charging barrel;
step S12, if yes, the pressure of injecting glue is 20-205kg/cm2Injecting the glue for 1.5-11.5s in 1-5 sections at the glue injection speed of 5-75 mm/s;
step S13, after the glue injection is finished, the pressure is maintained at 47-57kg/cm2Keeping the pressure for 0-8.5 s.
It can be understood that the injection molding machine is provided with an injection mold designed for a bottom shell of a printer and a sol feeding component; the feeding sol component is used for feeding and dissolving sol, the heated and dissolved sol is temporarily stored in the charging barrel, a glue injection gun is arranged in the injection mold and used for injecting the sol in the charging barrel into the injection mold, the injection mold comprises a front mold and a rear mold, the front mold and the rear mold form an injection molding space after the mold is closed, and the sol is injected into the injection molding space by the glue injection gun to form the bottom shell of the printer.
Further, before injecting the glue, whether the mold is closed or not is firstly detected, namely whether the front mold and the rear mold are closed or not is detected to form an injection molding space; meanwhile, whether sufficient sol exists in the charging barrel is also detected; the injection step is started if and only if the mould has been closed and there is sufficient sol in the barrel.
When injecting glue, the pressure of injecting glue in the glue gun is controlled to 20-205kg/cm2And injecting the glue for 1.5-11.5s in 1-5 sections at the glue injection speed of 5-75 mm/s. It can be understood that the glue gun will need a certain glue injection pressure to inject the sol into the mold; the glue injection speed refers to the flowing speed of the sol in the glue injection gun; it is emphasized that the glue injection process is divided into 1-5 stages for glue injection, and the glue injection is not completed by injecting all the sol at one time; the sol can be made to fully fill the mold through sectional glue injection; for example, the sol can be injected into the farthest position of the glue injection gun in advance, and then the sol sequentially approaches the glue injection gun, so that the sol is fully filled in the injection space in the mold, the problems of structure loss, burrs and the like of the bottom shell of the printer due to insufficient sol are effectively solved, the surface saturation and the surface smoothness are effectively improved, and the product yield is improved.
Finally, after the glue injection is finished, the glue injection amount is still 47-57kg/cm2Keeping the pressure for 0-8.5s under the pressure keeping pressure. It can be understood that after the injection of the glue is completed, the pressure of the sol in the injection mold is maintained; and then make sol more abundant fill in injection mold, also can get rid of simultaneously the bubble in the sol, and then effectively promote the yield of printer drain pan.
Preferably, the step S12 further includes:
if yes, the pressure of injecting glue is 25-200kg/cm2And injecting the glue for 3-6.5 s in 1-5 sections at the glue injection speed of 10-70 mm/s.
Further, the step S12 specifically includes:
injecting glue at the 1 st stage with the glue injection pressure of 95-105kg/cm2Injecting glue at the glue injection speed of 60-70 mm/s;
injecting glue at the 2 nd stage with the pressure of 195-205kg/cm2Injecting glue at the glue injection speed of 65-75 mm/s;
injecting glue at the 3 rd stage with the glue injection pressure of 80-90kg/cm2Injecting glue at the glue injection speed of 60-70 mm/s;
injecting glue at the 4 th stage with the glue injection pressure of 49-59kg/cm2Injecting glue at the glue injection speed of 10-20 mm/s;
injecting glue at the 5 th stage with the glue injection pressure of 20-30kg/cm2And injecting the glue at the glue injection speed of 5-15 mm/s.
That is, in the injection molding and glue injection control method S10 for the bottom case of the printer according to the present invention, the glue injection is divided into 5 sections; the 1 st section of injection is injection at a position which is 128-148mm away from the injection point; the 2 nd section of glue injection is performed at a position 45-65mm away from a glue injection point; the 3 rd stage of glue injection is performed at a position which is 25-45mm away from a glue injection point; and the 4 th section of glue injection and the 5 th end of glue injection are glue injection at positions 12-32mm away from the glue injection point. It should be noted that the distance from the glue injection point is the position of the glue injection gun from the glue injection point at different positions of the injection space of the mold. It can be understood that the glue is injected in a segmented mode, the glue injection pressure and the glue injection speed are controlled, the fact that the injection mold is fully filled with the sol is effectively guaranteed, and the product yield of the bottom shell of the printer is improved.
In a specific embodiment, the step S12 is configured to:
injecting glue at the 1 st stage at the position 138mm away from the glue injection point under the glue injection pressure of 100kg/cm2Injecting glue at the glue injection speed of 65 mm/s;
injecting glue at the 2 nd stage with the glue injection pressure of 200kg/cm at the position 55mm away from the glue injection point2Injecting glue at the glue injection speed of 70 mm/s;
injecting glue at the 2 nd stage with the glue injection pressure of 85kg/cm at the position 35mm away from the glue injection point2Injecting glue at the glue injection speed of 65 mm/s;
injecting glue at the 4 th stage at the position 22mm away from the glue injection point under the glue injection pressure of 54kg/cm2Injecting glue at the glue injection speed of 15 mm/s;
injecting glue at the 5 th stage with the glue injection pressure of 25kg/cm at the position 22mm away from the glue injection point2Injecting glue at the glue injection speed of 10 mm/s;
and the total glue injection time of the 1 st section of glue injection, the 2 nd section of glue injection, the 3 rd section of glue injection, the 4 th section of glue injection and the 5 th section of glue injection is 3.2s or 4.8 s.
Further, the step S13 further includes pressure-maintaining glue injection, wherein the glue injection speed of the pressure-maintaining glue injection is 10-20 mm/S. It can be understood that, at the time of pressure holding after injection of the glue, if an unfilled injection space exists in the previous injection mold, or bubbles or the like exist in the sol; the sol can be extruded, and the sol is more abundant among the messenger injection mold, however, this also causes local disappearance sol among the injection mold, and is being carried out the pressurize and is penetrated the gluey sol that can effectively supply this moment, and then effectively promotes printer drain pan injection moulding product yield.
In one embodiment, the sol in the injection mold is filled at 52kg/cm after the injection is completed2Maintaining the pressure under the pressure maintaining pressure; synchronously performing pressure maintaining injection on the injection mold at the injection speed of 15mm/s while maintaining the pressure; meanwhile, the pressure maintaining and pressure maintaining glue injecting time is 3.3 s. That is, the pressure maintaining and the pressure maintaining glue injection are synchronously carried out in the implementation, and the whole process time is 3.3 s; can understand, penetrate through synchronous pressurize and glue, can effectively guarantee the complete quilt among the injection mold the sol is filled, effectively avoids printer drain pan to cause structure disappearance, burr scheduling problem because of the sol is not enough, has effectively promoted surface saturation and surface smoothness, has improved the product yield.
In some embodiments, the injection molding and glue injecting control method of the printer bottom shell S10 includes that after pressure maintaining and glue injecting, the glue injecting gun has a residual amount of sol, and the residual amount of sol is 8-20 mm; furthermore, the residual amount of the sol can be 10-17.5 mm; specifically, the residual amount of the sol is any one of 8mm, 9mm, 10.1mm, 17.5mm, 18mm, and 20 mm. It can be understood that the surface saturation and smoothness of the printer bottom shell are regulated by controlling the amount of sol residue in the injection gun.
The invention also provides a printer bottom shell which is used for assembling a printer, wherein the printer bottom shell is processed by the injection molding and glue injection control method S10 of the printer bottom shell provided by the invention. Therefore, the printer bottom shell provided by the invention has higher surface saturation and surface smoothness due to the adoption of the injection molding and glue injection control method S10 of the printer bottom shell, so that the appearance of the printer shell is effectively improved. It should be noted that the injection molding glue injection control method S10 for the bottom case of the printer provided by the present invention can also be used for controlling glue injection in the injection molding manufacturing process of the outer case of the television, the monitor, or the computer.
Compared with the prior art, the invention provides a printer bottom shell and an injection molding and glue injection control method thereof, wherein the injection molding and glue injection control method of the printer bottom shell is used for controlling an injection mold of an injection molding machine to inject glue to prepare the printer bottom shell and comprises the steps of detecting whether a mold is closed or not and whether sufficient sol exists in a charging barrel or not; if yes, the pressure of injecting glue is 20-205kg/cm2Injecting the glue for 1.5-11.5s in 1-5 sections at the glue injection speed of 5-75 mm/s; after the injection is finished, the pressure is maintained at 47-57kg/cm2Keeping the pressure for 0-8.5 s. And then make the sol fully fill in the mould injection space, effectively avoid the printer drain pan because of the not enough structure of causing of sol lacks, burr scheduling problem, effectively promoted surface saturation and surface smoothness, improved the product yield.
