Description

Technical Field

[0001] The invention belongs to the technical field of lampshade production, in particular to a lampshade injection molding device. Background Art

[0002] Lampshade injection molding equipment is an injection molding machine specially used for producing lampshades. The working principle of this type of equipment is usually to feed loose granular or powdered molding materials into a high-temperature barrel to heat, melt and plasticize them, making them into a viscous melt. Then, the plastic melt is compressed and pushed forward by a plunger or a screw, passing through the nozzle at the front end of the barrel at a faster flow rate and injected into the closed mold cavity with a lower temperature. After a period of pressure holding and cooling molding, the mold is opened to remove the lampshade plastic product with a certain shape and size from the mold cavity. Common types can be divided into vertical injection molding machines and horizontal injection molding machines.

[0003] When the existing vertical injection molding equipment for lampshades injects the plastic melt into the cavity between the molds, an injection groove needs to be opened on the top. When the plastic melt is injected downward through the injection groove, part of the plastic melt will be cooled and fixed on the top of the molded product, which will cause the protruding part to affect the appearance. Therefore, the top needs to be cut separately, which ultimately greatly improves the efficiency of the lampshade injection molding production, so it needs to be improved. Summary of the invention

[0039] The upper mold 5 is driven downward to fit the lower mold 4 through the lifting mechanism 2, and then the injection molding mechanism 6 can be driven to perform injection molding on the inner cavities of the lower mold 4 and the upper mold 5 through the injection molding groove 7. After the injection is full, the bottom end of the first pneumatic component 8 will be squeezed upward, so that the middle bottom end of the flattening mechanism 10 can be driven downward by the second pneumatic component 9 to flatten the plastic melt at the bottom of the injection molding groove 7.

[0040] like Figures 1 to 3 As shown, a rotating plate 3 located below an upper mold 5 is disposed on the top of the vertical injection molding machine body 1 , and a lower mold 4 is disposed on the top of the rotating plate 3 .

[0041] The above solution is adopted: by providing a rotating disk 3, the operator can drive the rotating disk 3 to rotate, so that the lower mold 4 on the top can be switched back and forth, and then the material can be taken through to perform continuous injection molding operations.

[0042] like Figures 1 to 3 As shown, the injection molding mechanism 6 includes an injection molding cylinder 601, a screw conveying mechanism 602 and a feeding hopper 603;

[0043] The injection cylinder 601 is fixedly installed on the top of one side of the lifting mechanism 2 , the screw conveying mechanism 602 is arranged inside the injection cylinder 601 , and the feeding hopper 603 is arranged on one side of the top of the injection cylinder 601 .

[0044] The above scheme is adopted: wherein the screw conveying mechanism 602 is a prior art equipment, which is composed of a screw conveying roller and a motor. The operator can continuously feed the plastic particles into the injection cylinder 601 through the feeding hopper 603, and then drive the plastic particles downward by starting the screw conveying mechanism 602, and heat them at the same time, so that the plastic particles become a plastic melt, and finally, they can be injected into the cavity formed by the close fit of the lower mold 4 and the upper mold 5 through the injection groove 7.

[0045] like Figure 4 and Fig.10 As shown, the linkage assembly 104 includes a fixed block 1041, a movable frame 1042 and an extrusion plate 1043;

[0046] The fixed block 1041 is arranged on the top of the flattening column 102, the movable frame 1042 is movably installed inside the injection cylinder 601 and is located outside the support cylinder 101, the extrusion plate 1043 is arranged on the inner side of the movable frame 1042 and is located inside the support cylinder 101, and the inner side of the extrusion plate 1043 is slidably connected to the outer side of the top of the fixed block 1041.

[0047] By adopting the above solution: by providing the squeezing plate 1043, when the two movable frames 1042 and the squeezing plate 1043 are driven to move toward each other as a whole, the inner inclined surface of the squeezing plate 1043 can squeeze and push the fixed block 1041 and the flattening column 102 to move downward as a whole.

[0048] like Figure 6 and Fig.10 As shown, the first pneumatic assembly 8 includes a first pneumatic cylinder 801, a first pneumatic piston rod 802 and a first connecting spring 803;

[0049] The first pneumatic cylinder 801 is arranged inside the lifting mechanism 2 and located outside the injection molding groove 7. The first pneumatic piston rod 802 is movably installed in the inner cavity of the first pneumatic cylinder 801. The bottom surface of the top end of the first pneumatic piston rod 802 is elastically connected to the inner wall of the first pneumatic cylinder 801 through the first connecting spring 803.

[0050] The above scheme is adopted: by providing a first connecting spring 803, when the bottom end of the first pneumatic piston rod 802 is squeezed and pushed upward, the first connecting spring 803 can be stretched, and when the squeezing force at the bottom of the first pneumatic piston rod 802 is released, the elastic force of the first connecting spring 803 will be released, pulling the first pneumatic piston rod 802 to reset downward as a whole.

[0051] like Figure 3 and Fig.10 As shown, the second pneumatic assembly 9 includes a second pneumatic cylinder 901, a second pneumatic piston rod 902 and a first ventilation groove 903;

[0052] The second pneumatic cylinder 901 is fixedly installed inside the injection cylinder 601 and is located on the inner side of the bottom outer end of the card slot 1402. The second pneumatic piston rod 902 is movably installed in the inner cavity of the second pneumatic cylinder 901, and the outer end is fixedly connected to the inner side of the bottom outer end of the card slot 1402. The second pneumatic cylinder 901 is connected to the inner cavity of the first pneumatic cylinder 801 through the first ventilation groove 903.

[0053] The above scheme is adopted: by providing a first ventilation groove 903, when the first pneumatic piston rod 802 is pushed upward as a whole, the gas at the top of the inner cavity of the first pneumatic cylinder 801 will enter the inner cavity of the second pneumatic cylinder 901 through the first ventilation groove 903, so that the air pressure in the inner cavity of the second pneumatic cylinder 901 becomes larger, which can push the two second pneumatic piston rods 902 and the movable frame 1042 to move towards each other.

[0054] like Figure 5 and Figure 6 As shown, the inner cavity of the upper mold 5 is provided with an exhaust groove 12 located outside the first pneumatic cylinder 801 , and the interior of the lifting mechanism 2 is provided with a shielding sealing component 11 located at the outer end of the exhaust groove 12 .

[0055] By adopting the above solution, the gas inside the cavity formed by the upper mold 5 and the lower mold 4 can be squeezed out smoothly through the design of the exhaust groove 12.

[0056] like Figure 5 , Figure 8 and Fig. 9 As shown, the shielding and sealing assembly 11 includes a shielding and sealing plate 1101, a rotating arm 1102, a rotating rod 1103, a disc air box 1104 and a second ventilation groove 1105;

[0057] The shielding sealing plate 1101 is movably installed inside the lifting mechanism 2 and is located inside the outer end of the exhaust groove 12. The disc air box 1104 is arranged inside the lifting mechanism 2 and is located on the inner side of the shielding sealing plate 1101. The rotating rod 1103 is movably sleeved on the middle part of the disc air box 1104. The rotating arm 1102 is fixedly sleeved on one end of the rotating rod 1103. One end of the bottom of the rotating arm 1102 extends to the inside of the top of the shielding sealing plate 1101. The disc air box 1104 is connected to the inner cavity at the bottom of the first pneumatic cylinder 801 through the second ventilation groove 1105.

[0058] The above scheme is adopted: by providing a shielding sealing plate 1101, and by installing the shielding sealing plate 1101 on the outer end of the exhaust groove 12, the outer end of the exhaust groove 12 can be pushed to shield and prevent dust. After that, when the first pneumatic piston rod 802 is pushed upward as a whole, the gap at the bottom of the inner cavity of the first pneumatic cylinder 801 will become larger and negative pressure will be generated. The gas in the inner cavity of the disc air box 1104 can be extracted through the second ventilation groove 1105, so as to drive the rotating rod 1103 and the rotating arm 1102 to rotate, and then the shielding sealing plate 1101 can be driven to move upward as a whole, thereby successfully releasing the shielding effect on the outer side of the exhaust groove 12.

[0059] like Figure 6 and Figure 8 As shown, a one-way valve assembly 13 is provided at the bottom of the inner side of the exhaust groove 12, and the one-way valve assembly 13 includes an air-permeable mesh plate 1301, a one-way valve column 1302 and a second connecting spring 1303;

[0060] The breathable mesh plate 1301 is fixedly installed at the bottom of the inner cavity of the exhaust groove 12, and the one-way valve column 1302 is movably installed in the inner cavity of the exhaust groove 12 and is located above the breathable mesh plate 1301. The one-way valve column 1302 is elastically connected to the inner wall of the exhaust groove 12 through the second connecting spring 1303.

[0061] The above solution is adopted: through the design of the breathable mesh plate 1301, the gas squeezed in the inner cavity of the lower mold 4 and the upper mold 5 can pass through it smoothly and enter the inner wall of the exhaust groove 12, and then push the one-way valve column 1302 as a whole upward, so that the gas passes through the gap between the one-way valve column 1302 and the exhaust groove 12 and is discharged upward from the outside.

[0062] like Figure 6 As shown, a fastening assembly 14 is provided inside the upper mold 5 between the one-way valve column 1302 and the first pneumatic piston rod 802, and the fastening assembly 14 includes a fastening clamping strip 1401, a clamping groove 1402 and a second return spring 1403;

[0063] The fastening strip 1401 is movably installed inside the upper mold 5 and is located between the one-way valve column 1302 and the first pneumatic piston rod 802. The slot 1402 is opened at the outer bottom of the first pneumatic piston rod 802. The fastening strip 1401 is elastically connected to the inner wall of the upper mold 5 through the second return spring 1403.

[0064] The above scheme is adopted: by providing a fastening strip 1401, when the breathable mesh plate 1301 moves upward as a whole, the inclined surface inside the fastening strip 1401 can be squeezed, thereby pushing the fastening strip 1401 to move towards each other, and at this time the inner end of the fastening strip 1401 is directly opposite to the slot 1402, and finally the inner cavity of the fastening strip 1401 can be stuck in the slot 1402, thereby fixing the first pneumatic piston rod 802 as a whole.

[0065] The working principle and use process of the present invention:

[0066] First, the operator can start the lifting mechanism 2 to drive the injection cylinder 601 and the upper mold 5 to move downward as a whole, so that the bottom of the upper mold 5 and the top of the lower mold 4 fit tightly, and then start the screw conveying mechanism 602 to heat the plastic particles in the injection cylinder 601 into a plastic melt and transport it through the injection groove 7 for injection molding to the cavity between the lower mold 4 and the upper mold 5.

[0067] When the plastic cylinder between the lower mold 4 and the upper mold 5 is full, the first pneumatic piston rod 802 will be pushed to move upward as a whole, so as to push the gas at the top of the inner cavity of the first pneumatic cylinder 801 into the inner cavity of the second pneumatic cylinder 901 through the first ventilation groove 903, and then the air pressure in the inner cavity of the second pneumatic cylinder 901 increases, which can push the two second pneumatic piston rods 902 to drive the movable frame 1042 and the extrusion plate 1043 to move towards each other. At this time, due to the sliding connection between the inner side of the extrusion plate 1043 and the two sides of the fixed block 1041, the inner inclined surface of the extrusion plate 1043 can squeeze and push the fixed block 1041 and the support cylinder 101 to move downward as a whole, so that the bottom end of the support cylinder 101 can smoothly flatten the plastic melt protruding from the bottom of the injection groove 7.

[0068] At the same time, when the first pneumatic piston rod 802 is upward as a whole, the gap in the inner cavity at the bottom of the first pneumatic cylinder 801 will become larger and generate negative pressure, thereby extracting the gas in the inner cavity of the disc air box 1104 through the second ventilation groove 1105. At this time, since the gap at the bottom of the inner cavity of the first pneumatic cylinder 801 is much larger than the inner cavity of the disc air box 1104, a large negative pressure will be generated to smoothly drive the rotating rod 1103 and the rotating arm 1102 to rotate, so that the outer part of the bottom end of the rotating arm 1102 can move in a circle in the inner cavity at the top of the shielding sealing plate 1101, and then the shielding sealing plate 1101 can be driven to move upward as a whole, and the shielding seal on the outer side of the exhaust groove 12 can be released, which is convenient for subsequent gas discharge.

[0069] Finally, while the plastic melt is flattened by the bottom end of the support cylinder 101, the gas inside the plastic melt will be squeezed through the breathable mesh 1301 into the inner cavity of the exhaust groove 12, and then the breathable mesh 1301 will be pushed upward as a whole, so as to pass through the gap between the breathable mesh 1301 and the exhaust groove 12 and be discharged to the outside world through the exhaust groove 12 in one direction. When the breathable mesh 1301 moves upward as a whole, it will push the outer inclined surface of the fastening strip 1401, and push the inner end of the fastening strip 1401 to be smoothly stuck in the inside of the groove 1402, so that the first pneumatic piston rod 802 can be fastened, and finally the lower mold 4 and the upper mold 5 can be smoothly injection molded.
