[0016] 2. In the invention, if the components are adhered to the surface of the movable mold after cooling and forming, and the ejection device cannot automatically push the components downward, the first movable plate is controlled to drive the multiple components above to move to the bottom close to the movable mold, and the two clamps are controlled to move upward together until the two clamps are respectively located on both sides of the movable mold, and the two clamps are used to clamp and fix the two sides of the components attached to the surface of the movable mold, and then the two third sliders are controlled to drive the two clamps to pull the components attached to the surface of the movable mold to the right end until the attached components are pulled off the surface of the movable mold.

Then, multiple electromagnets are controlled to be energized to generate magnetism, so that multiple connecting plates can be magnetically fixed to the outer walls of the movable mold and the static mold. As the telescopic ends of the multiple first electric telescopic rods are controlled to extend upward, the second movable plate and the mold on top of it are driven to move upward to the top of the shell. With the help of the double limit fixation of the two clamping plates and the electromagnets inside the multiple connecting plates, the safety and stability of the mold moving upward to the top of the shell are improved, and there is no need to manually disassemble the mold, thereby improving the efficiency of mold disassembly and maintenance.

[0018] 4. In the present invention, when installing a new mold inside the shell, the second movable plate can be controlled to move to the top of the shell, and the new mold can be placed on the top of the second movable plate.

[0031] As a technical optimization solution of the present invention, a connecting plate 19 is installed at one end of the two shielding curtains 21 away from the second groove 32, and two electromagnets 20 are installed inside the two connecting plates 19. When the two movable strips 17 move toward the direction of approaching each other, they drive the two clamping plates 15 to move together in the direction of approaching each other, and drive the rotating plates 18 on both sides of the two clamping plates 15 to move together, until the two groups of rotating plates 18 move to abut against each other, and then use the electromagnets 20 set inside the multiple connecting plates 19 to attract each other, and then control the two clamping plates 15 to move and reset in the direction of moving away from each other, and pull the shielding curtain 21 to the unfolded state, so as to guide the parts falling downward, so that the two clamping plates 15 can accurately clamp and fix the parts.

[0032] As a technical optimization solution of the present invention, two sets of second electric telescopic rods 33 are installed on the inner bottom surface of the cavity 9, and the telescopic ends of the two sets of second electric telescopic rods 33 are installed with placement plates 12. The telescopic ends of the two sets of second electric telescopic rods 33 are extended, which can drive the two placement plates 12 to move out from the inside of the cavity 9.

[0033] In the present invention, when the user uses the device, the plastic raw material is fed into the barrel 3 through the hopper 2 for heating and melting, and then the barrel 3 discharges the melted plastic raw material through the nozzle into the static mold 5 and the movable mold 6 for injection molding. After a period of cooling, the movable mold 6 moves away from the static mold 5, so that the molded component automatically falls downward from the inside of the mold into the inside of the cavity 9.

[0034] Since a feeding mechanism is provided inside the cavity 9, during the cooling and molding process of the plastic raw material injected inside the mold, Figure 4 As shown, the two movable strips 17 can be controlled to move in the direction of approaching each other, driving the two clamping plates 15 and the two groups of rotating plates 18 to move in the direction of approaching each other, until the two groups of rotating plates 18 move to abutting state, and then the electromagnets 20 inside the multiple connecting plates 19 are controlled to be energized to generate magnetism, so that the two corresponding connecting plates 19 are magnetically fixed, and then the two movable strips 17 are controlled to drive the two clamping plates 15 to move and reset in the direction of moving away from each other, and drive the shielding curtains 21 inside the multiple second grooves 32 to be expanded, and control the multiple rotating plates 18 to rotate downward in the direction away from the clamping plates 15 to be inclined. After the components inside the mold are cooled and formed, the movable mold 6 and the static mold 5 are separated, and the components are automatically pushed down by the provided ejecting device. The components that fall downward fall between the two groups of rotating plates 18 in an inclined state, and the components are guided and limited by multiple expanded shielding curtains 21, which can also have a flexible buffering effect on the components.

[0035] After the component is located between the two clamping plates 15, the multiple rotating plates 18 are controlled to rotate and reset in the direction close to the clamping plates 15. The component is located between the two clamping plates 15 in a vertical state, and the two clamping plates 15 are controlled to move in the direction close to each other at the same time, and the two ends of the component in the vertical state are clamped and limited. Then, the multiple rotating plates 18 can be controlled to rotate downward to a horizontal state, so that the component is clamped and fixed by the two clamping plates 15 at this time. After the component is inspected with the help of the preset appearance inspection equipment inside the body 1, if the component is qualified, the two first sliders 16 can be controlled to drive the first movable plate 13 and the multiple components on the top of it to move toward the left end to the vicinity of the placement plate 12 close to the left side, and the two clamping plates 15 are controlled to rotate to the left side, and then the two third sliders 31 are controlled to move in the corresponding third slide grooves 30. The interior slides toward the left end, driving the two clamps 15 and the components to move to the top of the left placement plate 12, and controlling the two clamps 15 to move in directions away from each other, so that the components fall downward on the top of the two shielding curtains 21 on the left, and are guided downward along the top of the two shielding curtains 21 on the left side that are tilted downward, and fall on the top of the placement plate 12 on the left for temporary storage. If the components are unqualified, the two first sliders 16 are used to drive multiple components to move toward the right end, and the two clamps 15 are controlled to rotate to the right, so that the unqualified components can be placed on the top of the placement plate 12 on the right, so as to achieve the effect of flexible unloading of components and automatic classification, avoid the problem of components falling directly downward and easily getting scratched on the surface, and can also indirectly improve the yield rate of components after injection molding.

[0036] At the same time, the components that subsequently fall between the two clamping plates 15 can be controlled to rotate by the two double-headed screws 27, driving the two corresponding moving blocks 26 to slowly move in the direction of approaching each other, thereby driving the second moving plate 14 and the multiple components above it to move upward together, so that the subsequent two clamping plates 15 rotate downward, and when the components are placed on the top of the two placement plates 12, they can be stacked up together in sequence until a sufficient number of components are stacked on the top of the two placement plates 12, and then the telescopic end of the second electric telescopic rod 33 is controlled to extend, driving the placement plate 12 to move out from the inside of the cavity 9, and thereby driving the stacked multiple components to be automatically discharged from the inside of the cavity 9, so that the staff can quickly take the components and improve the efficiency of component injection molding.

[0037] If the component is separated from the movable mold 6 and the static mold 5 after cooling and forming, and the component is adhered to the surface of the movable mold 6, the ejecting device cannot automatically push the component downward. At this time, after the movable mold 6 and the static mold 5 are separated, the first movable plate 13 can be controlled to drive the multiple components above to move to the bottom close to the movable mold 6, and the two double-headed screws 27 can be controlled to rotate to drive the second movable plate 14 and the two clamping plates 15 above it to move upward together, until the two clamping plates 15 are respectively located on both sides of the movable mold 6, and the two clamping plates 15 are used to move in a direction close to each other to clamp and fix the two sides of the component attached to the surface of the movable mold 6, and then the two third sliders 31 are controlled to move toward the right end inside the corresponding third slide groove 30, and the components attached to the surface of the movable mold 6 are pulled to the right end by means of the two clamping plates 15 until the attached components are pulled off the surface of the movable mold 6. There is no need to stop the machine body 1 and clean it manually to avoid affecting the injection molding efficiency of the components.

[0038] If the mold needs to be disassembled for inspection or replacement, the two double-headed screws 27 can be used to rotate and push the second movable plate 14 to move upward until it abuts against the bottom ends of the movable mold 6 and the static mold 5. At this time, the two clamping plates 15 are respectively located on both sides of the mold. First, the two clamping plates 15 are controlled to move in a direction close to each other, so that the two clamping plates 15 are tightly abutted against the outer walls on both sides of the mold, which has a clamping and fixing effect on the mold. Then, the multiple rotating plates 18 are controlled to rotate downward in a direction away from the clamping plates 15 and be in an inclined state, so that the rotating plates 18 on both sides of the two clamping plates 15 are respectively abutted against the outer walls on both sides of the movable mold 6 and the static mold 5. The electromagnets 20 inside the multiple connecting plates 19 can be controlled to be energized to generate magnetism, so that the multiple connecting plates 19 can It is magnetically fixed to the outer walls of the movable mold 6 and the static mold 5 to improve the fixing effect of the mold, the multiple bolts between the multiple telescopic columns 8 and the mounting seat 7 are removed, and the multiple telescopic columns 8 are controlled to shrink, and then the static mold 5 is removed from the inner wall of one side of the shell 4, so that the movable mold 6 and the static mold 5 can be supported by the second movable plate 14 below, and as the telescopic ends of the multiple first electric telescopic rods 23 are controlled to extend upward, the second movable plate 14 and the mold on top of it are driven to move upward to the top of the shell 4. With the help of the double limit fixation of the two clamping plates 15 and the internal electromagnets 20 of the multiple connecting plates 19, the safety and stability of the mold moving upward to the top of the shell 4 are improved, and there is no need to manually disassemble the mold, thereby improving the efficiency of mold disassembly and maintenance.

[0039] When installing a new mold inside the shell 4, the second movable plate 14 can be controlled to move to the top of the shell 4, and the new mold can be placed on the top of the second movable plate 14. After being fixed with the help of two clamping plates 15 and multiple connecting plates 19, the process of moving the mold to the inside of the shell 4 is safer and more stable, and it can also facilitate subsequent staff to quickly install the movable mold 6 and the static mold 5 without the need for additional lifting or other fixing equipment, thereby further improving the applicability of the feeding mechanism.

[0040] If only the movable mold 6 or the static mold 5 needs to be disassembled and repaired, the movable mold 6 is controlled to be separated from the static mold 5, and then the two clamps 15 below are controlled to move to the bottom of the movable mold 6 or the static mold 5 that needs to be disassembled, and after the two clamps 15 are controlled to move upward a distance, the top ends of the two clamps 15 clamp and fix the two sides of the movable mold 6 or the static mold 5, and then the second movable plate 14 drives the two clamps 15 to move upward together, pushing the movable mold 6 and the static mold 5 that need to be disassembled to move upward to the top of the shell 4. After the staff takes them away, the remaining movable mold 6 and the static mold 5 are in an exposed state, and the above-mentioned steps of unfolding the multiple shielding curtains 21 can be repeated to unfold the multiple shielding curtains 21, and move them inside the third slide groove 30 with the help of two third sliders 31, driving the unfolded shielding curtains 21 to shield and protect the remaining movable mold 6 or static mold 5, to prevent external debris from adhering to the surface of the movable mold 6 or static mold 5 inside the shell 4, which affects the subsequent use of the mold.

[0041] If it is not necessary to disassemble the movable mold 6 or the static mold 5 for maintenance, and only to perform maintenance directly inside the shell 4, refer to Figure 5 As shown, after controlling multiple shielding curtains 21 to unfold, and then controlling multiple rotating plates 18 to rotate downward to a horizontal state, when the staff is inspecting and maintaining the mold above, the parts or lubricating oil that falls downward can fall down on the top of the unfolded shielding curtains 21, and fall on the top of the second movable plate 14 along the lower end of the shielding curtains 21, to prevent parts from falling into the dead corner of the cavity 9 and affecting the subsequent normal operation of the internal parts of the cavity 9; and the lubricating oil that falls on the top of the shielding curtains 21 can be guided to the top of the second movable plate 14, and by controlling the two movable strips 17 to move back and forth on the top of the second movable plate 14, the lubricating oil that falls on the top of the second movable plate 14 is evenly spread on its surface, to avoid the waste of this part of the lubricating oil dripping downward, to facilitate the subsequent back and forth movement of the two movable strips 17 on the top of the second movable plate 14, and to improve the smoothness of the movement of the two movable strips 17.
