[0021] Example 1:

[0029] Embodiment two:

[0030] Please refer to Figures 1 to 6 , compared with embodiment one, the end assembly 6 of the embodiment further comprises a fixing frame 61 clamped and fixed at the end of the side surface of the multi-axis mechanical arm 5; a high-transparency plate is arranged in the middle side of the bottom plate of the fixing frame 61, and a sensor 62 with data acquisition function is fixedly installed on the top side of the high-transparency plate through bolts; an array of through holes is arranged on the outer circle of the bottom plate of the fixing frame 61, and a negative pressure suction accessory 63 is slidingly arranged in the through holes; an electromagnetic cylinder 64 is arranged on the outer side of the negative pressure suction accessory 63, and the negative pressure suction accessory 63 is fixedly installed on the top of the bottom plate of the fixing frame 61; a multi-way valve 65 with flow guiding function is fixedly arranged on the top plate of the fixing frame 61 through bolts.

[0031] The negative pressure suction accessory 63 comprises a straight rod air pipe 631 slidingly arranged on the through hole of the bottom plate of the fixing frame 61, and cast iron blocks 632 are arranged on the outer side wall of the straight rod air pipe 631.

[0032] A micro valve 633 with flow guiding function is fixedly inserted at the top end of the straight rod air pipe 631, and the micro valve 633 is fixedly connected with the valve port of the multi-way valve 65 through a connecting pipe.

[0033] The micro valve 633 is an electromagnetic control type two-position two-way valve, which is electrically connected with the control panel 2 through a signal line; the bottom end of the straight rod air pipe 631 is sleeved with a sealing suction disc 634 made of flexible high-temperature-resistant material.

[0034] The working principle of the above-mentioned injection molding equipment and injection molding process for high-good-quality micro structure parts is as follows: Firstly, when using the equipment, first place the equipment in the working area, then connect the device with the external power supply, and the equipment can provide the power required for work; Secondly, first drive the movable mold plate of the mold part 3 to move towards the fixed mold by the injection molding machine 1, complete the mold closing, and form the cavity of the micro structure part; at this time, the molten plastic material is injected into the closed cavity through the injection head driven by the hydraulic cylinder of the injection part 4, the injection feeding pipeline and the valve; Thirdly, during the injection process, the components in the solidification seat assembly 31 and the plasticizing seat assembly 32 are started to work at the same time, the ultrasonic generator 316 installed on the sliding inner core 312 emits high-frequency vibration to the molten material in the cavity of the mold part 3, which can effectively eliminate the internal stress of the material, promote the uniform arrangement of molecular chains, reduce bubbles, and accelerate the solidification process of the material from the surface and the inside, thereby improving the physical properties of the material and shortening the molding cycle; Fourth, during the injection molding and holding pressure processes, the gas generated in the mold cavity can be discharged through the micropores of the high-density metal mesh 3112 and the polymer breathable membrane 3113 below it. The polymer breathable membrane allows gas to pass through but can effectively block the molten plastic, thereby avoiding defects such as burning and material shortage caused by trapped gas in the mold cavity, while ensuring the effective transmission of the holding pressure. At the same time, the control panel 2 controls the external temperature control device to circulate hot or cold medium into the annular air pipe 3132 through the first quick connector 315; the hot medium flows through the guide tube 3133 to the heat conducting column 3134, and the heat is efficiently transferred to the surface of the polymer breathable membrane 3113 via the heat conducting column, thereby controlling the overall temperature of the polymer breathable membrane 3113 to prevent it from being affected by the temperature of the melt and losing its function. At the same time, the injection of suitable hot and cold media can also prevent premature cooling that causes insufficient filling or weld marks, and can achieve rapid cooling and shaping. Fifth, by controlling the injection molding machine 1 to drive the mold 3 to open, the multi-axis robotic arm 5, under the command of the control panel 2, carries the end assembly 6 and moves precisely to the top of the mold cavity. The sensor 62 on the end assembly 6 is set as a visual sensor. It uses a high-transmittance plate to capture images of the molded part in the mold and transmits the data back to the control panel 2. The system can determine whether the product is fully molded and has no defects through image analysis, and accurately calculate its position coordinates to guide the robotic arm to accurately grasp it. Sixth, the control panel 2 is responsible for distributing the external negative pressure source to each micro valve 633 according to the part position and contour information fed back by the sensor, and the multi-way valve 65 is responsible for individually controlling the on and off of each micro valve 633, thereby activating the negative pressure adsorption component 63 at the corresponding position. The sealing suction cup 634 at the bottom of the activated straight rod air pipe 631 generates suction under the action of negative pressure, firmly adsorbing the specific point of the micro part. The electromagnetic cylinder 64 is energized to generate a magnetic field, which attracts the cast iron block 632, so that the straight rod air pipe 631 overcomes the friction and slides upward or downward, adjusting the position until the sealing suction cup 634 is tightly fitted to the surface of the part. The design allows the end assembly 6 to adapt to micro-parts of different heights and micro-curves, ensuring uniform distribution of gripping force and avoiding damage to fragile micro-parts due to concentrated force or insufficient gripping force; the piston and piston rod in the plasticizing seat assembly 32 are pushed toward each other by the magnetic field between the coil block 3111 and the permanent magnet 3131, which is equivalent to an ejector system, gently ejecting the molded micro-part from the fixed mold side, separating it from the mold cavity, and facilitating grasping by the multi-axis robot arm 5. After successfully grasping the part, the multi-axis robot arm 5 moves it to the designated position, then releases the negative pressure and releases the part, completing a working cycle.

[0035] The present invention provides an improved injection molding device and injection molding process for high-quality micro-structural parts. By integrating ultrasonic vibration, intelligent ventilation and exhaust systems and precise temperature control, the internal quality and surface integrity of micro-injection molded parts are significantly improved, and the molding cycle is shortened. At the same time, the system uses machine vision to perform online quality inspection and positioning, and adopts a negative pressure gripping system with adaptive posture adjustment to achieve non-destructive, flexible and precise automatic pickup of tiny precision parts, ultimately forming a set of efficient, high-quality and highly automated precision injection molding production solutions.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
