Description

Technical Field

[0001] The present application relates to the technical field of plastic molds, and in particular to a two-color plastic mold. Background Art

[0002] With the continuous expansion of the e-cigarette market and the continuous improvement of consumers' demand for the appearance and functions of e-cigarettes, the design and production of e-cigarette products have gradually shown a trend of diversification and personalization. Two-color plastic mold technology has received widespread attention and application because it can give products a two-color or multi-color appearance. Two-color plastic mold technology, also known as double-material injection molding technology, is a mold technology that combines two different colors of plastics through a one-time molding process. This technology can make e-cigarette products have richer colors and textures, and enhance their beauty and attractiveness. At the same time, due to the relatively low manufacturing cost and high production efficiency of two-color injection molds, they have been widely used in the e-cigarette industry.

[0003] The existing technology still has the following problems: 1. One of the main functions of the buffer mechanism of the traditional mold is to reduce the impact and vibration generated by the mold during the mold closing or opening process, which causes the internal parts of the movable mold to tilt after long-term use, resulting in the size and shape of the produced product deviating from the design requirements, and the mold deviating or deforming, thus affecting the overall quality and appearance of the product. In addition, it is difficult to observe the tilt of the internal parts of the equipment with the naked eye, resulting in the production of batches of unqualified products.

[0004] 2. Traditional molds cannot process electronic cigarettes of different lengths. Different molds are required for injection molding when producing electronic cigarettes of different lengths. After the workpiece is thermoformed, due to the close fit between the mold and the workpiece and the possible friction, the injection molded parts may be deformed or scratched on the surface when they are ejected or manually pulled out using a demolding mechanism that is too rigid. This damage may affect the dimensional accuracy, appearance quality and performance of the workpiece, and the injection molded parts will be subjected to uneven forces, causing deformation and wear of the injection molded parts. In addition, when demolding two-color plastics, both sets of molds need to wait until the demolding is completed before injection molding, which reduces production efficiency.

[0020] In case of tilting of internal parts due to long-term use, the present invention can reduce impact and vibration when closing or opening the mold through the buffer component, and can timely discover when the mold and the equipment body are tilted, thereby ensuring the alignment of the mold when closing or opening the mold; for electronic cigarettes that cannot be processed in different lengths, the present invention can produce injection molded parts of different lengths according to demand through the demoulding component, and the workpiece can be ejected by flexible force through the demoulding mechanism after shaping.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] See also Figure 1 and Figure 2As shown, a two-color plastic mold comprises a fixed mold frame 1, wherein guide grooves 2 are provided at four corners of the fixed mold frame 1, and the inner cavity of the guide groove 2 is slidably connected with a guide column 3, and the end of the guide column 3 away from the fixed mold frame 1 is fixedly connected with a movable mold frame 4, and the inner cavity of the movable mold frame 4 is provided with a buffer component 5, and the inner cavity of the fixed mold frame 1 is provided with a demoulding component 6. The fixed mold frame 1 and the movable mold frame 4 are approached, and the guide column 3 slides in the inner cavity of the guide groove 2, and the buffer component 5 and the demoulding component 6 are used for injection molding of the mold. At the same time, the buffer component 5 has a buffering effect, which reduces the impact and vibration of the fixed mold frame 1 and the movable mold frame 4, and can judge whether there is inclination between the buffer component 5 and the movable mold frame 4, so as to ensure that the fixed mold frame 1 and the movable mold frame 4 are aligned during injection molding, so as to produce qualified products, and the demoulding component 6 is used for flexible demoulding, and the equipment can perform injection molding and demoulding at the same time, which reduces the waiting time for demoulding in the process flow and improves production efficiency.

[0023] See also Figure 3 and Figure 4 As shown, the buffer assembly 5 includes a buffer frame 51, an upper mold 52 is installed at both ends of the buffer frame 51, a guide rod 53 is fixedly installed on the outer surface of the buffer frame 51, a buffer mechanism 54 is fixedly installed on the outer surface of the buffer frame 51, a level detection mechanism 55 is provided in the inner cavity of the buffer mechanism 54, and an adjustment mechanism 56 is provided on the outer surface of the buffer mechanism 54. The guide rod 53 is slidably connected with the movable mold frame 4, there are two upper molds 52, and the cavities of the two upper molds 52 are different. The guide rod 53 is used to limit the buffer frame 51, so that the buffer assembly 5 is flexibly fixed in the inner cavity of the movable mold frame 4 as a whole, and the upper mold 52 and the membrane cavity groove 62 are connected to each other for injection molding to produce electronic cigarette products. There are two upper molds 52 for injection molding of two colors respectively. The alternating work with the demoulding can significantly reduce the waiting time, thereby reducing the overall production cycle. The buffer mechanism 54 is used for buffering between devices. The horizontal detection mechanism 55 is used to detect whether the upper mold 52 and the movable mold frame 4 are tilted, thereby causing the upper mold 52 and the demoulding assembly 6 to tilt. When the equipment is tilted, the horizontal detection mechanism 55 can send a lift to maintain the equipment. At the same time, the adjustment mechanism 56 can adjust the angle of the horizontal detection mechanism 55, so as to detect whether there is a tilt between the upper mold 52 and the movable mold frame 4 from various angles, thereby ensuring that the output of the injection molded parts is qualified.

[0024] See also Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the buffer mechanism 54 includes a support frame 541, a fixed rod 542 is fixedly installed on the inner wall of the support frame 541, a sliding sleeve 543 is slidably connected to the outer surface of the fixed rod 542, a first spring 544 is sleeved on the outer surface of the fixed rod 542, there are two sliding sleeves 543, the first spring 544 is located between the two sliding sleeves 543, one end of the sliding sleeve 543 is rotatably connected to a connecting strip 545, and the end of the connecting strip 545 away from the sliding sleeve 543 is rotatably connected to a buffer plate 546, the outer surfaces of the support frame 541 and the buffer frame 51 are fixedly connected, and the buffer mechanism 54 is located in the middle of the two upper molds 52, and the horizontal detection mechanism 55 includes a detection frame 551, the inner cavity of the detection frame 551 is slidably connected to a slide seat 552, and one end of the slide seat 552 is sleeved with a second Spring 553, the inner cavity of the slide 552 is rotatably connected with a pressure ring 554, the inner cavity of the detection frame 551 is rotatably connected with a first rotating rod 555, the outer surface of the first rotating rod 555 is fixedly connected with a floating seat 556, the outer surface of the first rotating rod 555 is fixedly installed with a pointer 557, the outer surface of the floating seat 556 is fixedly installed with a detection plate 558, and the two ends of the detection plate 558 are rollingly connected with a first rolling ball 559, and the first rolling ball 559 and the inner wall of the movable mold frame 4 are tightly fitted, so that the first rolling ball 559 can roll on the inner wall of the movable mold frame 4 during the rotation of the detection plate 558, so that the angle of the detection plate 558 changes, which is convenient for checking whether the tilt occurs between the buffer assembly 5 and the movable mold frame 4 at each angle, and the outer surface of the detection frame 551 is provided with a first rolling ball 559. A button 5510 is provided, and an alarm 5511 is fixedly installed on the outer surface of the detection frame 551. The second spring 553 is located between the slide 552 and the inner wall of the detection frame 551. The detection frame 551 and the buffer plate 546 are rotatably connected in the middle part.

The first button 5510 and the alarm 5511 are electrically connected. The pressing of the first button 5510 controls the alarm 5511 to sound an alarm. There is a gap between the two ends of the floating seat 556 and the detection frame 551. When the fixed mold frame 1 and the movable mold frame 4 fit together, the movable mold frame 4 drives the horizontal detection mechanism 55 to squeeze the horizontal detection mechanism 55. At this time, the buffer mechanism 54 drives the buffer frame 51 to approach the demolding component 6, so that The upper mold 52 and the membrane cavity groove 62 are fitted together. In this process, the buffer mechanism 54 is used to buffer the impact of the fixed mold frame 1 and the movable mold frame 4. During the impact, the buffer plate 546 approaches the support frame 541. At this time, the connecting strip 545 rotates to drive the sliding sleeve 543 to slide on the fixed rod 542. The two sliding sleeves 543 squeeze the first spring 544. The elastic force of the first spring 544 reduces the impact and vibration generated by the impact between the fixed mold frame 1 and the movable mold frame 4, thereby reducing equipment wear. When the buffer frame 51 tilts as a whole, it causes the upper mold 52 and the buffer mechanism 54 to tilt, which makes it easy to produce unqualified products during injection molding. However, the horizontal detection mechanism 55 can promptly alarm the tilt of the buffer component 5. The tilt of the buffer frame 51 drives the detection frame 551 to tilt.Since the first rolling ball 559 contacts the inner wall of the movable mold frame 4, when the detection frame 551 tilts, the detection plate 558 and the detection frame 551 have an angle deviation, that is, the detection plate 558 drives the first rotating rod 555 to rotate in the inner cavity of the detection frame 551. At this time, the floating seat 556 squeezes the pressure ring 554 to drive the slide seat 552 to slide in the inner cavity of the detection frame 551, and the second spring 553 is compressed. The rotation of the first rotating rod 555 drives the pointer 557 to rotate, and the rotation of the pointer 557 drives the pointer 557 to squeeze the first button 5510. The squeezing of the first button 5510 causes the alarm 5511 to sound an alarm, reminding the staff that the upper mold 52 and the movable mold frame 4 are tilted as a whole, so that the membrane cavity groove 62 and the upper mold 52 cannot be aligned when the fixed mold frame 1 and the movable mold frame 4 are opened and closed, affecting the quality of the injection molded product. Through the present application, timely maintenance is performed when the upper mold 52 is tilted, so as to avoid the tilt between the molds during injection molding and fail to be discovered in time, and prevent the production of batch defective products.

The bottom end of the stripping module 655 is rollingly connected with a second rolling ball 656. The fourth spring 654 is located between the adjusting seat 651 and the stripping module 655. When the mold 61 rotates, the second rolling ball 656 passes through the upper surface of the protrusion 642, and the height of the second rolling ball 656 is lower than the top of the protrusion 642 and higher than the two ends of the protrusion 642. When demolding, the second motor drives the second rotating rod 63 to rotate, and the rotation of the second rotating rod 63 drives the lower mold 61 to rotate, so that the inner cavity of the membrane cavity groove 62 that has completed two injections passes through the lifting mechanism 64. At this time, the second rolling ball 656 contacts the protrusion 642, and the protrusion 642 squeezes the second rolling ball 656, driving the demolding module 655 to squeeze the ejector rod 653 to compress the fourth spring 654. At this time, the ejector rod 653 is ejected from the inner cavity of the support plate 652, driving the ejector rod 653 to eject the injection molded part in the inner cavity of the membrane cavity groove 62, thereby realizing demolding. When the demolding is completed, the lower mold 6 1 continues to rotate, the second rolling ball 656 and the protrusion 642 are out of contact, and the push rod 653 and the support plate 652 are re-formed into one under the elastic force of the fourth spring 654, which is convenient for the next injection molding. The flexible force is used during demoulding. When the injection molded part and the inner cavity of the membrane cavity groove 62 are stuck together, the second rolling ball 656 squeezes the protrusion 642. At this time, the protrusion 642 slides in the inner cavity of the lifting frame 641, and the protrusion 642 squeezes the third spring 645 so that the bottom end of the protrusion 642 presses the third button 644. The pressing of the third button 644 drives the speaker 643 to sound an alarm, reminding the staff to inspect the equipment to prevent damage to the injection molded parts or equipment produced. The height of the protrusion 642 is adjusted by adjusting the position of the lifting frame 641 on the adjusting bolt 646.This facilitates the demoulding mechanism 65 to always be in contact with the protrusion 642 during the lifting process. That is, when producing injection molded parts of different lengths, the second bolt 648 is rotated to disengage the second bolt 648 from the engagement with the clamping hole 647, and the position of the lifting frame 641 on the adjusting bolt 646 is moved. When the position is appropriate, the second bolt 648 and the clamping hole 647 are engaged again, so that the height of the lifting frame 641 can be adjusted.

[0028] See also Fig.10 and Fig.13 As shown, the adjustment mechanism 66 includes a fixed plate 661, the outer surface of the fixed plate 661 is slidably connected to a slider 662, the outer surface of the slider 662 is fixedly installed with a driving rod 663, the four corners of the outer surface of the fixed plate 661 are fixedly installed with a storage rod 665, the inner cavity of the storage rod 665 is slidably connected to an upgrade rod 666, the inner cavity of the fixed plate 661 is rotatably connected to a threaded rod 667, the bottom end of the upgrade rod 666 is fixedly connected to a lifting plate 668, the upper surface of the lifting plate 668 is fixedly installed with a support rod 669, the slider 662 and the threaded rod 667 are threadedly connected, the driving rod 663 and the driving groove 664 are slidably connected, the support rod 669 and the inner wall of the adjustment seat 651 are fixedly connected, and the fixed plate 661 and the lower surface of the lower mold 61 are fixedly connected. When it is necessary to produce electronic cigarette injection molded parts of different lengths, the slider 662 is driven to slide on the fixed plate 661 by rotating the threaded rod 667, and the sliding of the slider 662 drives the driving rod 663 to move in the inner cavity of the driving groove 664. At this time, the upgrading rod 666 slides in the inner cavity of the storage rod 665, so that the driving rod 663 drives the lifting plate 668 to move, so that the lifting plate 668 drives the height of the support rod 669 to change, and the support rod 669 drives the height of the demolding mechanism 65 to change, so that the depth of the support plate 652 in the inner cavity of the membrane cavity groove 62 changes, thereby changing the length of the electronic cigarette injection molded parts and producing products of different specifications. The height adjustment of the demolding mechanism 65 cooperates with the height adjustment of the protrusion 642 to achieve the adjusted demolding process.

[0029] In summary, the fixed mold frame 1 and the movable mold frame 4 are brought close to each other, and the guide column 3 slides in the inner cavity of the guide groove 2. The buffer component 5 and the demoulding component 6 are used for injection molding. At the same time, the buffer component 5 has a buffering effect, which reduces the impact and vibration of the fixed mold frame 1 and the movable mold frame 4. At the same time, it can judge whether there is a tilt between the buffer component 5 and the movable mold frame 4, and ensure that the fixed mold frame 1 and the movable mold frame 4 are aligned during injection molding, so as to produce qualified products. The demoulding component 6 is used for flexible demoulding, and the equipment can perform injection molding and demoulding at the same time, reducing the waiting time for demoulding in the process flow and improving production efficiency. The guide rod 53 is used to limit the buffer frame 51, so that the buffer component 5 is flexibly fixed in the inner cavity of the movable mold frame 4 as a whole, and the upper mold 52 and the membrane cavity groove 62 are connected to perform injection molding to produce electronic cigarette products. There are two upper molds 52 for injection molding of two colors respectively, and the cooperation with demoulding to achieve alternating work can significantly reduce the waiting time, thereby reducing the overall production cycle. The buffer mechanism 54 is used for buffering between equipment, and the level detection Mechanism 55 is used to detect whether the upper mold 52 and the movable mold frame 4 are tilted, thereby causing the upper mold 52 and the demoulding assembly 6 to tilt. When the equipment is tilted, the horizontal detection mechanism 55 can be lifted to maintain the equipment. At the same time, the adjustment mechanism 56 can adjust the angle of the horizontal detection mechanism 55, so as to detect whether there is a tilt between the upper mold 52 and the movable mold frame 4 from various angles, thereby ensuring that the output injection molded parts are qualified. The lower mold 61 is controlled to rotate by the second motor, so that two membrane cavity grooves 62 are located below the upper mold 52 for simultaneous injection molding. The second motor also adopts a stepping motor, which is convenient for accurately controlling the rotation angle of the second rotating rod 63, so that when two membrane cavity grooves 62 are injected, the other membrane cavity groove 62 completes injection molding and the demoulding mechanism 65 is lifted by the lifting mechanism 64 for demoulding. That is, the two-color mold is produced by injection molding through the first upper mold 52 and then secondary injection molding through the second upper mold 52 to produce a two-color injection molded product, and finally demoulding is carried out through the lifting mechanism 64.
