Embodiment 1

[0036] In order to solve the problems existing in the prior art that different injection molded parts use the same injection molding process to cause serious defects such as product flashes and burrs, and the problem of complicated operation of changing the injection molding process to ensure product quality. The invention provides a multi-injection molding device for one-time molding, refer to figure 1 As shown, the device includes an electric control box 1 and an injection molding machine 2 controlled by a PLC controller, and the injection molding machine 2 is used to complete at least one injection molding process, including a mold clamping system 21, and the mold clamping system 21 includes a mold 211, the mold 211 is provided with a filling control structure corresponding to the injection molding process one by one, the filling control structure includes a miniature oil cylinder, a miniature oil cylinder limit sensor and a solenoid valve, and the miniature oil cylinder lim...

Embodiment 2

[0045] In order to solve the problems existing in the prior art, the present invention also provides a method of multi-injection molding at one time, specifically, refer to figure 2 As shown, the method includes the following steps:

[0046] S1, turn on the power;

[0047] S2. Set the injection molding process on the control panel 23 of the injection molding machine, and turn the manual / automatic switch on the electric control box 1 to the automatic position;

[0048] S3. On the touch input screen, input the position parameters of the screw and the pressure holding time when the filling is completed and meet the process switching conditions;

[0049] S4, close the safety door;

[0050] S5. Put the on-off switch in the open position and start the injection molding machine 2. Specifically, when the injection molding machine 2 is started, the mold clamping starts. If the injection molding machine 2 fails to start, the mold clamping fails, and the injection molding machine 2 wi...

Embodiment 3

[0060] In this embodiment, the injection molding machine completes three injection molding processes. Specifically, the difference from Example 1 is that the injection molding process includes injection molding process I, injection molding process II and injection molding process III. The difference from embodiment 2 is that , on the touch input screen, input the position parameters that the screw needs to reach when the filling of injection molding process I and injection molding process II is completed, so as to determine the switching from injection molding process I to injection molding process II, and switching from injection molding process II to injection molding process II Toggle condition.

[0061] In this embodiment, it also includes 3# miniature oil cylinder, 3# miniature oil cylinder limit sensor and solenoid valve III. The position sensor is used to sense the signal of the 3# miniature oil cylinder to push out to the limit and back to the limit, and transmit the s...

Abstract

The invention relates to the technical field of injection molding technologies, and discloses a device and method for achieving one-time molding through multiple injection molding technologies. The device comprises an electric control box and an injection molding machine controlled by a PLC; the injection molding machine is used for completing at least one injection molding technology and comprises a mold closing system, the mold closing system comprises a mold and a hot runner, filling control structures corresponding to the injection molding technologies one to one are arranged in the mold, each filling control structure comprises a micro oil cylinder, a micro oil cylinder limiting sensor and an electromagnetic valve, the micro oil cylinder limiting sensors are connected with the input end of the PLC, the micro oil cylinders and the electromagnetic valves are connected with the output end of the PLC, and the electric control box is provided with injection molding technology switches corresponding to the injection molding technologies one to one. According to the device and method, the problems that the defects such as flash and burrs of a product are serious due to the fact that different injection molding parts are machined through a same injection molding technology, and the operation of changing the injection molding technology for ensuring the product quality is complex are solved.

Description

technical field [0001] The invention relates to the technical field of injection molding technology, and discloses a multi-injection molding technology one-time molding device and method. Background technique [0002] Injection molding machine is a kind of plastic production equipment that can form plastic products with complex shape, precise size or dense texture with metal inserts at one time. It is to add granular or powdery plastic into the barrel, and through the rotation of screw Heating the outer wall of the machine barrel to make the plastic melt, then the machine clamps the mold and the injection seat moves forward, so that the nozzle is close to the gate of the mold, and then the injection cylinder is filled with pressure oil to push the screw forward, so that High pressure and fast speed inject the molten material into the closed mold with low temperature. After a certain period of time and pressure maintenance (also known as holding pressure), cooling, it is soli...
