[0032] Example 1:

[0033] Please see Figures 1-6The present invention discloses an injection molding equipment and injection molding process for high-quality micro-structural parts, comprising an injection molding machine 1; a control panel 2 is bolted to the left displacement plate of the injection molding machine 1; mold parts 3 are bolted to the left frame and the side of the displacement plate of the injection molding machine 1; an injection part 4 with injection function is bolted to the top side of the injection molding machine 1; and a multi-axis robotic arm 5 with adjustment function is bolted to the front end of the injection molding machine 1, and an end component 6 is clamped and fixed at the end of the multi-axis robotic arm 5.

[0034] The mold component 3 specifically includes a moving mold and a fixed mold that are respectively fixedly installed on the frame and displacement plate of the injection molding machine 1, and the sides of the moving mold and the fixed mold are respectively fixedly installed with a curing seat assembly 31 and a plasticizing seat assembly 32 by bolts.

[0035] The curing seat assembly 31 includes a locking seat 311 that is fixedly mounted on the side of the mold part 3 by bolts; a circular hole is provided at the center of the locking seat 311, and a sliding inner core 312 is fixedly mounted inside the circular hole by bolts; the sliding inner core 312 is slidably disposed at the center hole of the displacement seat 313; a folding tube 314 is fixedly disposed between the locking seat 311 and the displacement seat 313, and an annular space is provided inside the displacement seat 313; a first quick connector 315 is inserted and fixedly mounted on the side of the displacement seat 313, and an ultrasonic generator 316 is threadedly mounted on the left side of the sliding inner core 312.

[0039] The injection component 4 specifically includes a hydraulic cylinder fixedly installed on the top of the injection molding machine 1, an injection head fixedly installed at the end of the piston rod of the hydraulic cylinder, and an injection feed pipe and valve connected to the injection head.

[0040] Example 2:

[0041] Please see Figures 1-6 The present invention provides an injection molding equipment and injection molding process for high-quality micro-structural parts. Compared with Embodiment 1, this embodiment further includes: the end component 6 includes a fixing frame 61 that clamps and fixes to the side end of the multi-axis robotic arm 5; a high-transparency plate is provided on the middle side of the base 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 by bolts; an array of through holes is provided on the outer ring of the base plate of the fixing frame 61, and a negative pressure adsorption component 63 is slidably arranged in the through holes; an electromagnetic cylinder 64 is provided on the outside of the negative pressure adsorption component 63, and the negative pressure adsorption component 63 is fixedly installed on the top of the base plate of the fixing frame 61; a multi-way valve 65 with a flow guiding function is fixed on the top plate of the fixing frame 61 by bolts.

[0042] The negative pressure adsorption component 63 includes a straight rod air pipe 631 that is slidably disposed on the through hole of the base plate of the fixed frame 61, and cast iron blocks 632 are arranged on the outer side wall of the straight rod air pipe 631.

[0043] A miniature valve 633 with a flow guiding function is inserted and fixed at the top end of the straight tube 631, and the miniature valve 633 is fixedly connected to the valve port of the multi-way valve 65 through a connecting pipe.

[0044] The miniature valve 633 is an electromagnetically controlled two-position two-way valve, which is electrically connected to the control panel 2 via a signal line; the bottom end of the straight rod air tube 631 is fitted with a sealing suction cup 634 made of flexible high-temperature resistant material.

[0045] The working principle of the injection molding equipment and injection molding process for high-quality micro structural parts described above is as follows:

[0046] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0047] Second, the moving platen of the mold part 3 is moved to the fixed mold by the injection molding machine 1 to complete the mold closing and form the cavity of the micro structure. Here, the hydraulic cylinder of the injection part 4 drives the injection head to inject the molten plastic material into the closed cavity through the injection feeding pipe and valve.

[0048] Third, during the injection molding process, the components in the curing seat assembly 31 and the plasticizing seat assembly 32 start working simultaneously. The ultrasonic generator 316 installed on the sliding inner core 312 emits high-frequency vibrations to the molten material in the cavity of the mold part 3. This vibration can effectively eliminate internal stress of the material, promote uniform molecular chain arrangement, reduce bubbles, and accelerate the curing process of the material from the surface to the inside, thereby improving the physical properties of the material and shortening the molding cycle.

[0049] Fourth, during injection molding and pressure holding, the gas generated in the 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 effectively blocks the molten plastic, thereby avoiding defects such as scorching and material shortage caused by trapped gas in the cavity. At the same time, it ensures the effective transmission of pressure holding. Meanwhile, 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 guide column 3134. The heat is efficiently transferred to the surface of the polymer breathable membrane 3113 through the heat guide column, controlling the overall temperature of the polymer breathable membrane 3113 to prevent it from losing its function due to the temperature of the melt. At the same time, injecting suitable hot or cold medium can also prevent premature cooling that leads to insufficient filling or weld lines, and can achieve rapid cooling and shaping.

[0050] Fifth, by controlling the injection molding machine 1 to drive the mold part 3 to open the mold, the multi-axis robotic arm 5, under the command of the control panel 2, carries the end component 6 to move precisely above the mold cavity. The sensor 62 on the end component 6, which is set as a vision sensor, collects images of the molded part inside the mold through the high-transparency plate and transmits the data back to the control panel 2. The system can determine whether the product is fully formed and whether there are any defects through image analysis, and accurately calculate its position coordinates to guide the robotic arm to perform precise grasping.

[0051] Sixth, based on the part position and contour information fed back by the sensors, the control panel 2 uses a multi-way valve 65 to distribute the external negative pressure source to each micro-valve 633, individually controlling the opening and closing of each micro-valve 633. This activates the corresponding negative pressure adsorption component 63. The sealing suction cup 634 at the bottom of the activated straight rod air tube 631 generates suction under the negative pressure, firmly adsorbing the specific point of the micro-part. The electromagnetic cylinder 64 is energized to generate a magnetic field, attracting the cast iron block 632, causing the straight rod air tube 631 to slide upwards or downwards against friction, adjusting its position until the sealing suction cup 634 is tightly attached to the surface of the part. The design allows the end component 6 to adapt to micro parts with different heights and micro-curved surfaces, ensuring a 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 towards each other by the magnetic field between the coil block 3111 and the permanent magnet 3131, which is equivalent to an ejector system. This gently pushes the molded micro part out from the fixed mold side, separating it from the mold cavity, so that it can be grasped by the multi-axis robotic arm 5. After successfully grasping the part, the multi-axis robotic arm 5 moves it to the designated position, then releases the negative pressure, releases the part, and completes one work cycle.

[0052] This invention provides an improved injection molding equipment and process for high-quality micro-structural parts. By integrating ultrasonic vibration, intelligent ventilation and exhaust system, and precise temperature control, it significantly improves the internal quality and surface integrity of micro-injection molded parts and shortens the molding cycle. At the same time, the system uses machine vision for online quality inspection and positioning, and adopts an adaptive negative pressure gripping system to achieve non-destructive, flexible, and precise automated part removal of tiny precision parts. Ultimately, it forms a highly efficient, high-quality, and highly automated precision injection molding production solution.
