Description

Technical Field

[0001] This invention belongs to the field of mold technology, and specifically relates to an injection mold for automotive seat trim panels based on the reuse of plastic scraps. Background Technology

[0002] Injection molds are precision tools used for the mass production of plastic parts. Through the injection molding process, molten plastic is injected into the mold cavity, and after cooling and solidification, a plastic product with a complete structure and precise dimensions is obtained. It is an indispensable core equipment in modern manufacturing and is widely used in numerous industries such as automotive, electronics, home appliances, medical, and packaging.

[0003] When using injection molds for car seat covers, the molded part and the scrap material solidified in the injection channel are exposed together as the two molds separate. The molded part and scrap material are then separated by the ejection mechanism on the mold, and the scrap material is reused. However, during the mold separation process, the excess scrap material is exposed to the air for a long time. Some scrap materials have a strong moisture absorption capacity, causing the scrap material to absorb a lot of moisture. When the scrap material is heated and melted later, the melting is incomplete, which seriously affects the quality of the product when the melted liquid is used for subsequent injection molding.

[0004] Therefore, it is necessary to invent an injection mold for automotive seat trim panels based on the reuse of plastic scraps to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an injection mold for automotive seat trim panels based on the reuse of plastic scraps, thereby solving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An injection mold for automotive seat trimming panels based on the reuse of plastic scrap includes a mold 1 and a mold 2. The inner side of the mold 1 is provided with an injection port, and the inner side of the mold 2 is provided with a flow channel corresponding to the injection port. The flow channel is connected to the cavity of the mold 2. The mold 1 is provided with a moisture-proof component, which can perform moisture-proof treatment on the molded scrap material extracted from the injection port.

[0008] The moisture-proof components include: a ring frame, a base, a telescopic cover, a magnetic plate, straps, a positioning component, a spreading component, a storage component, and a stop block;

[0009] The mold has an annular groove on its inner side, located at the injection port. The base is fixedly installed on the inner wall of the annular groove. The ring frame is disposed within the annular groove. The two ends of the telescopic cover are connected to the ring frame and the base, respectively. The magnetic plate is disposed inside the ring frame. The positioning component can position the ring frame within the annular groove. The strap is sleeved on the outside of the telescopic cover. The spreading component can spread the strap. The storage component is disposed on the base for storing the telescopic cover. The stop block is fixed on the inner wall of the annular groove for blocking the ring frame.

[0010] Furthermore, the positioning component includes: a push plate, a protrusion, and a spring;

[0011] The ring frame has equidistant movable cavities inside, the push plate is slidably disposed in the movable cavity, the protrusion is fixedly installed on the side of the push plate away from the injection port, one end of the protrusion extends to the outside of the movable cavity and abuts against the inner wall of the ring groove, and the spring fixes the side of the push plate near the injection port and the inner wall of the movable cavity.

[0012] Furthermore, the spreading assembly includes: a bracket, a support plate, teeth, and a rack;

[0013] The bracket is fixedly installed equidistantly around the side of the ring frame near the base. One end of the support plate is fixedly installed with a shaft, which is rotatably installed inside the bracket. The teeth are equidistantly arranged at one end of the support plate near the ring frame. The rack meshes with the teeth. The ring frame has an opening that communicates with the movable cavity. One end of the push plate passes through the opening and is fixedly connected to the rack. The outer side of the support plate has a notch, and the strap is fitted into multiple notches.

[0014] Furthermore, the storage component includes: guide wheels and a motor;

[0015] The motor is fixedly mounted inside the base at equal intervals, and the guide wheel is fixedly mounted on one end of the motor's output shaft. The outer side of the guide wheel abuts against the outer side of the telescopic cover.

[0016] Furthermore, the base has an internal cavity, which is connected to the interior of the telescopic cover through multiple air holes, and the outside of the mold is provided with an inflation component that can inject hot air into the cavity.

[0017] Furthermore, the inflation assembly includes: a blower, a mounting bracket, a moisture-absorbing bag, and a heating assembly;

[0018] The blower is fixedly installed on the outside of the mold one via a carrier plate. The mounting bracket is located at the air intake end of the blower. The moisture-absorbing bag is located inside the mounting bracket. The heating component is connected to the air outlet end of the blower.

[0022] Furthermore, the material of the ring frame is the same as that of the mold, and the ring frame is in close contact with the inner wall of the ring groove.

[0023] Furthermore, after the support plate rotates 45 degrees, the strap can detach from the notch.

[0025] 1. This invention, through the cooperation of a ring frame, base, telescopic cover, magnetic plate, strap, positioning component, spreading component, and storage component, enables the scrap material extracted from the injection port to be moisture-proofed, preventing 90% of the scrap material from coming into contact with external moisture, thereby ensuring that 90% of the molded scrap material remains dry and can be reused normally in the future.

[0026] 2. This invention injects air into the telescopic cover, filling it with air to support the ring frame and prevent it from falling rapidly downwards. This prevents scrap materials from separating from the telescopic cover due to inertia when falling rapidly, thus avoiding the scrap materials getting wet on the ground. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0035] This invention provides an injection mold for automotive seat trimming panels based on the reuse of plastic scraps, such as... Figures 1 to 6 As shown, it includes mold 1 and mold 2. Mold 1 and mold 2 are existing injection molds for automotive seat panels. Mold 1 has an injection port 3 on its inner side, and mold 2 has a runner 20 on its inner side corresponding to the injection port 3. The runner 20 is connected to the cavity of mold 2. Mold 1 is equipped with a moisture-proof component, which can protect the molded scrap material extracted from the injection port 3 from moisture.

[0036] The moisture-proof components include: ring frame 4, base 5, telescopic cover 6, magnetic plate 7, straps 8, positioning component, expansion component, storage component, and stop block 21;

[0037] The inner side of mold 1 is provided with an annular groove, which is located at injection port 3. Base 5 is fixedly installed on the inner wall of the annular groove. Ring frame 4 is set in the annular groove. The two ends of telescopic cover 6 are respectively connected to ring frame 4 and base 5. Magnetic plate 7 is set inside ring frame 4. Positioning component can position ring frame 4 in annular groove. Strap 8 is sleeved on the outside of telescopic cover 6. Spreading component can spread strap 8. Storage component is set on base 5 for storing telescopic cover 6. Stop block 21 is fixed on the inner wall of annular groove for blocking ring frame 4. The material of telescopic cover 6 is fluororubber.

[0038] In use, mold 2 is combined with mold 1, and molten plastic is injected through injection port 3. The molten plastic enters the cavity through flow channel 20. After cooling and molding, mold 2 is separated from mold 1. Magnetic plate 7 attracts ring frame 4 onto mold 2. As mold 2 moves, ring frame 4 moves against the positioning component, thus pulling open telescopic cover 6. At this time, the storage component reverses its operation to release telescopic cover 6. When strap 8 leaves the ring groove, the opening component releases the strap 8, and strap 8 retracts and binds to telescopic cover 6. The telescopic cover 6 is thus bound together with the molded scrap material extracted from the injection port 3, sealing the gap between the telescopic cover 6 and the molded scrap material extracted from the injection port 3. Then, the mold 2, carrying the ring frame 4, continues to move, continuously pulling the telescopic cover 6 open. The telescopic cover 6 wraps around the molded scrap material extracted from the injection port 3. Finally, the mold 2 stops moving, and the ejection mechanism on the mold 2 separates the molded scrap material from the molded part, ejecting the molded scrap material and the ring frame 4 away from the mold 2. The ring frame 4 separates from the mold 2, and under the influence of gravity... Under the action of the telescopic cover 6, the ring frame 4 and the scrap material descend. Finally, due to the traction of the telescopic cover 6, the ring frame 4 and the scrap material stop moving. Because the straps 8 bind the telescopic cover 6 to the scrap material, the scrap material will not detach from the telescopic cover 6. The scrap material is then extracted from the telescopic cover 6 for further reuse. The telescopic cover 6 is retracted by the storage component. When the telescopic cover 6, carrying the ring frame 4, moves to the front of the ring groove, the storage component stops after completing its work. Then, the straps 8 are opened by the spreading component, resetting the ring frame 4. The positioning component then fixes the ring frame 4, and the stop block... 21 can prevent the ring frame 4 from continuing to move deeper into the ring groove, ensuring that the surface of the ring frame 4 is flush with the surface of the injection port 3. During the entire mold opening and part removal process, it can wrap the molded scrap pulled out from the injection port 3, preventing 90% of it from coming into contact with external moisture, thus ensuring that 90% of the molded scrap is in a dry state, ensuring normal reuse in the future. The gap between the telescopic cover 6 and the molded scrap pulled out from the injection port 3 is sealed by the strap 8, so that moisture can be prevented from entering the telescopic cover 6 and the molded scrap can be prevented from getting damp.

[0039] like Figure 3 As shown, the positioning assembly includes: a push plate 9, a protrusion 10, and a spring 11;

[0040] The ring frame 4 has movable cavities arranged equidistantly inside. The push plate 9 is slidably disposed in the movable cavity. The protrusion 10 is fixedly installed on the side of the push plate 9 away from the injection port 3. One end of the protrusion 10 extends to the outside of the movable cavity and abuts against the inner wall of the ring groove. The spring 11 fixes the side of the push plate 9 near the injection port 3 and the inner wall of the movable cavity.

[0041] The spring force of spring 11 keeps push plate 9, protrusion 10 in contact with the inner wall of the annular groove. The friction between protrusion 10 and the inner wall of the annular groove prevents the ring frame 4 from dislodging from the annular groove.

[0042] like Figure 3 and Figure 5 As shown, the expansion assembly includes: a bracket, a support plate 12, teeth, and a rack 13;

[0043] The bracket is fixedly installed equidistantly around the side of the ring frame 4 near the base 5. A shaft is fixedly installed at one end of the support plate 12 and is rotatably installed in the bracket. The teeth are equidistantly arranged at one end of the support plate 12 near the ring frame 4. The rack 13 meshes with the teeth. An opening communicating with the movable cavity is opened on the ring frame 4. One end of the push plate 9 passes through the opening and is fixedly connected to the rack 13. A notch is provided on the outer side of the support plate 12. The strap 8 is fitted into multiple notches.

[0044] When the protrusion 10 moves away from the annular groove along with the ring frame 4, the compressed spring 11 returns to its original position, thereby pushing the push plate 9 and the protrusion 10 to move away from the injection port 3. The push plate 9 moves with the rack 13, causing the mating teeth to rotate the support plate 12 towards the injection port 3. When the strap 8 leaves the annular groove, the support plate 12 rotates to 45 degrees, and the stretched strap 8 returns to its original position to shrink, thus disengaging from the recess and finally binding the telescopic cover 6 to the scrap material. There are at least four support plates 12. When a reset is needed, multiple protrusions 10 are pressed simultaneously to move them towards the injection port 3 to retract. Conversely, the push plate 9 moves with the rack 13, thereby driving the support plate 12 to rotate and reset. Then, the strap 8 is stretched open to enter the recess, and the ring frame 4 is reset to enter the annular groove. Finally, under the push of the spring 11, the protrusion 10 abuts against the inner wall of the annular groove, positioning the ring frame 4.

[0045] like Figure 3 As shown, the storage components include: guide wheels 14 and a motor (not shown in the figure).

[0046] The motor is fixedly mounted inside the base 5 at equal intervals, and the guide wheel 14 is fixedly mounted on one end of the output shaft of the motor. The outer side of the guide wheel 14 abuts against the outer side of the telescopic cover 6.

[0047] At least four guide wheels 14 are provided. The motor output shaft drives the guide wheels 14 to rotate forward, thereby pushing the telescopic cover 6 out of the annular groove by friction, so that the telescopic cover 6 is released. The motor output shaft drives the guide wheels 14 to rotate in reverse, and vice versa, it drives the telescopic cover 6 back into the annular groove by friction.

[0048] like Figures 2 to 6 As shown, the base 5 has a cavity inside, and the cavity is connected to the inside of the telescopic cover 6 through multiple air holes 15. The outside of the mold 1 is provided with an inflation component that can fill the cavity with hot air. The inflation component includes: a blower 16, a mounting frame, a moisture-absorbing bag 17, and a heating component.

[0049] The blower 16 is fixedly installed on the outside of the mold 1 by a carrier plate. The mounting bracket is set at the air intake end of the blower 16. The moisture absorption bag 17 is set inside the mounting bracket. The heating component is connected to the air outlet end of the blower 16. The outside of the mold 1 is provided with a channel communicating with the cavity. One end of the heating component is connected to the channel.

[0050] After the strap 8 binds the scrap material to the telescopic cover 6, the blower 16 is started to draw out the outside air. The outside air is dehumidified by the moisture-absorbing bag 17 and then heated by the heating component to the same temperature as the scrap material. The air is then injected into the cavity through the channel, and the hot flow is injected into the telescopic cover 6 through the air hole 15. When the mold 2 stops, the telescopic cover 6 is filled with air. Then the blower 16 stops. After the ring frame 4 separates from the mold 2, the telescopic cover 6 is filled with air, which supports the ring frame 4 and prevents it from falling down quickly. This prevents the scrap material from separating from the telescopic cover 6 due to inertia when it falls quickly.

[0051] like Figure 6 As shown, the heating assembly includes: a mounting housing 18 and an electric heating grid 19;

[0052] One end of the mounting housing 18 is connected to the air outlet of the blower 16, and the other end of the mounting housing 18 is connected to the channel. The electric heating grid 19 is installed inside the mounting housing 18.

[0053] Activate the electric heating network 19 to heat the air passing through it, ensuring that the air temperature matches the temperature of the scrap material, thus preventing water droplets from forming on the surface of the scrap material due to temperature differences.

[0054] When mold 2 and ring frame 4 are attached, magnetic plate 7 can attract and fix ring frame 4 to the surface of mold 2.

[0055] The material of ring frame 4 is the same as that of mold 1. Ring frame 4 is in close contact with the inner wall of ring groove. The gap between ring frame 4 and ring groove is the same as the gap between mold 2 and its own ejection mechanism, so that the gap between ring frame 4 and ring groove will not affect injection molding.

[0056] After the support plate 12 rotates 45 degrees, the strap 8 can then detach from the notch.

[0057] Working principle: In use, mold 2 is combined with mold 1, and molten plastic is injected through injection port 3. The molten plastic enters the cavity through flow channel 20. After cooling and molding, mold 2 is separated from mold 1. Magnetic plate 7 attracts ring frame 4 onto mold 2. As mold 2 moves, ring frame 4 overcomes the friction between protrusion 10 and the inner wall of the ring groove and moves outward, thus pulling open telescopic cover 6. At the same time, the motor is started, and the motor output shaft drives guide wheel 14 to rotate forward, thereby pushing telescopic cover 6 out of the ring groove by friction, releasing telescopic cover 6. When protrusion 10 leaves the ring groove, the compressed spring 11 returns to its original position, thereby pushing push plate 9 and protrusion 10 away from the injection port. The mold 3 moves in the direction of the injection port 3, and the push plate 9 moves with the rack 13, causing the mating teeth to rotate the support plate 12 towards the injection port 3. When the binding strap 8 disengages from the annular groove, the support plate 12 rotates to 45 degrees, and the stretched binding strap 8 returns to its original position and shrinks, disengaging from the notch, and finally binding the telescopic cover 6 to the scrap material, sealing the gap between the telescopic cover 6 and the molded scrap material extracted from the injection port 3. Then, the mold 2, with the ring frame 4, continues to move, continuously pulling the telescopic cover 6 open. The telescopic cover 6 wraps the molded scrap material extracted from the injection port 3. Finally, the mold 2 stops moving, and the ejection mechanism on the mold 2 separates the molded scrap material from the molded part, and moves the molded scrap material and the ring frame 4 away from the molded part. The mold 2 ejects outwards, separating the ring frame 4 from the mold 2. Under the influence of gravity, it lowers along with the molded scrap. Finally, due to the traction of the telescopic cover 6, the ring frame 4 and the scrap stop moving. Because the strap 8 binds the telescopic cover 6 to the molded scrap, the molded scrap will not detach from the telescopic cover 6. Then, the molded scrap is pulled out from the telescopic cover 6 for further reuse. The motor is started to reverse its output shaft. Conversely, the telescopic cover 6 is pulled into the ring groove by friction. When the telescopic cover 6 moves with the ring frame 4 to the front of the ring groove, the motor is turned off. At the same time, multiple protrusions 10 are pressed to move them closer to the injection port 3 and retract them. Conversely, the push plate 9 moves, causing the rack 13 to move accordingly, thus cooperating with the gears. The tooth drive support plate 12 rotates and resets, then the strap 8 is opened so that the strap 8 enters the notch, and then the ring frame 4 is reset so that it enters the ring groove. Finally, under the push of the spring 11, the protrusion 10 abuts against the inner wall of the ring groove, positioning the ring frame 4 and completing the reset of the ring frame 4. During the entire mold opening and part removal process, the molded scrap material pulled out from the injection port 3 can be wrapped, preventing 90% of it from contacting the external moisture, thus ensuring that 90% of the molded scrap material can be kept dry and can be reused normally in the future. The gap between the telescopic cover 6 and the molded scrap material pulled out from the injection port 3 is sealed by the strap 8, so that moisture can be prevented from entering the telescopic cover 6 and the molded scrap material can be prevented from getting damp.

[0058] After the strap 8 binds the scrap material to the telescopic cover 6, the blower 16 is started to draw in outside air. The outside air is dehumidified by the moisture-absorbing bag 17 and then heated by the heating component to the same temperature as the scrap material. The air is then injected into the cavity through the channel, and the hot flow is injected into the telescopic cover 6 through the air hole 15. When the mold 2 stops, the telescopic cover 6 is filled with air. Then the blower 16 stops. After the ring frame 4 separates from the mold 2, the telescopic cover 6 is filled with air, which supports the ring frame 4 and prevents it from falling down quickly. This prevents the scrap material from separating from the telescopic cover 6 due to inertia when it falls quickly, thus avoiding the scrap material from getting wet on the ground.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
