Description

Technical Field

[0001] This application relates to the field of glove box molding technology, and in particular to an anti-warping automotive glove box molding process and molding die. Background Technology

[0002] The glove box is a storage space integrated into the dashboard in the car's cockpit, usually located in the leg area of ​​the passenger seat. It is named after the fact that it was originally designed for drivers to store their gloves. Currently, glove boxes can be manufactured in various ways, such as injection molding, blow molding, pressure molding, or composite molding, with injection molding being the most frequently used.

[0003] The prior art discloses an injection mold for an inner frame of an automotive glove box, comprising a fixed mold, a first limiting groove on the top of the fixed mold, a hollow box between the inner walls of the first limiting groove, a condenser tube inside the hollow box, both ends of the condenser tube slidingly extending to the outside of the hollow box, second limiting grooves on both sides of the fixed mold, trapezoidal support frames fixedly mounted on the outer surfaces of both sides of the fixed mold, round rods on one outer surface of each of the two trapezoidal support frames, handles fixedly mounted on one end of each of the two round rods, and limiting blocks fixedly mounted on the other end of each of the two round rods, the two limiting blocks slidingly extending into the hollow box, springs on the outer surfaces of each of the two round rods, a top cover on the top of the hollow box, a sealing ring adhered to the outer surface of the top cover, a moving mold on the top of the fixed mold, and a third limiting groove on the bottom of the moving mold.

[0004] Regarding the aforementioned technologies, after injection molding is completed, the injection molded product is separated from the fixed mold by the moving mold. Then, the low-temperature air generated by the condenser exchanges heat with the injection molded product. After the temperature of the injection molded product drops and its shape is fixed, the product is demolded. This process takes a long time. During this cooling and demolding process, the mold is occupied and cannot be used for the next injection molding, which seriously affects the injection molding efficiency of automotive glove boxes. Summary of the Invention

[0005] To improve the injection molding efficiency of automotive glove boxes, this application provides a molding process and mold for anti-warping automotive glove boxes.

[0006] The technical solution provided in this application for an anti-warping automotive glove box molding process and mold is as follows: In one aspect, this application provides an anti-warping automotive glove box molding die.

[0007] A mold for forming an anti-warping automotive glove box includes: A fixed mold, wherein two cores are connected to the top wall of the fixed mold, and the two cores can overlap after rotation; The moving mold has two cavities on the side near the fixed mold, and the core extends into the cavity to form a gap that fits the glove box. A load-bearing base is located on the side of the fixed mold away from the moving mold, and a rotating unit is provided on the load-bearing base. The rotating unit is connected to the fixed mold and is used to drive the fixed mold to rotate around the rotation axes of the two cores.

[0008] By adopting the above technical solution, the fixed mold and the moving mold are installed in the corresponding positions on the injection molding machine. After the moving mold and the fixed mold are closed, a gap is formed between the core and the cavity that can accommodate the glove box. Then, the molten plastic granules are injected into the cavity of the mold in the closed state until it is full. Then, the cavity is cooled and shaped. At this time, the moving mold retracts, and the glove box stays on the core and separates from the moving mold. Then, the fixed mold is rotated by the rotating unit, so that the core moves the glove box to the bottom of another cavity. The mold is closed again to cool and shape the glove box. At the same time, the cavity near the injection nozzle... The process involves injection molding a new glove box, followed by mold opening and removal of the molded glove box. The designed anti-warping automotive glove box molding die, through a fixed mold, a moving mold, and a core, forms a molding space after mold closing for injection molding or cooling and shaping of the glove box. A load-bearing base provides support for the fixed mold during mold closing, and a rotating unit drives the core through the fixed mold. This allows for simultaneous injection molding of the new glove box and cooling and shaping of the old glove box, thereby improving both the molding quality and the injection molding efficiency of the automotive glove box.

[0009] In one specific implementation scheme, a lower cooling channel is provided on the fixed mold, the lower cooling channel extends into the core, and a liquid supply unit is connected to the outside of the lower cooling channel. The liquid supply unit is used to input and return coolant into the lower cooling channel.

[0010] By adopting the above technical solutions, the designed liquid supply unit and lower cooling channel can achieve control of the core temperature, thereby controlling the flowability of the injection molding compound and the cooling speed of the glove box, and improving the molding quality of the automotive glove box.

[0011] In one specific implementation scheme, the moving mold has an upper cooling channel that surrounds the periphery of the two cavities, and the moving mold is connected to two electrically controlled conductive pipes. The lower cooling channel has a sliding conductive section formed in it for the insertion of the electrically controlled conductive pipes. The upper cooling channel and the lower cooling channel are connected through the electrically controlled conductive pipes.

[0012] By adopting the above technical solution, the designed upper cooling channel can work in conjunction with the lower cooling channel to further and comprehensively realize the temperature control in the two cavities. At the same time, the electrically controlled conductive pipe can also serve as an intermediate conductive structure to realize the connection between the upper and lower cooling channels while realizing the mold closing guidance of the fixed mold and the moving mold.

[0013] In one specific implementation, at least one rubber sealing ring is coaxially sleeved on the outer periphery of the electrically controlled conductive tube.

[0014] By adopting the above technical solution, the designed rubber sealing ring can reduce the possibility of coolant leakage through the gap between the electrically controlled conductive pipe and the sliding conductive section during mold closing.

[0015] In one specific implementation, the rotating unit includes A rotary motor is connected to the load-bearing base, and the output shaft of the rotary motor is coaxial with the rotational coincident axis of the two cores; A polygonal rod, one end of which is connected to the output shaft of the rotary motor, and the other end of which passes through the load-bearing base and extends into the fixed mold, and is slidably connected to the fixed mold; A telescopic mechanism is installed on the load-bearing base and can be connected to the fixed mold to drive the fixed mold to move toward or away from the load-bearing base.

[0016] By adopting the above technical solution, the designed rotating unit can realize the rotation of the fixed mold through the cooperation of a rotary motor and a polygonal rod, thereby completing the transfer of the glove box between the two cavities. The telescopic mechanism can realize the separation of the fixed mold and the load-bearing base before rotation, thereby reducing the resistance of the fixed mold rotation.

[0017] In one specific implementation, the telescopic mechanism includes The support frame has a receiving cavity on the load-bearing base for accommodating the support frame, and the support frame is slidably connected to the load-bearing base. The polygonal rod is offset from the support frame. Multiple driving hydraulic cylinders are provided, which are connected to the load-bearing base. The piston rod of the driving hydraulic cylinder is aligned with the axial direction of the output shaft of the rotary motor, and the piston rod of the driving hydraulic cylinder abuts against the support frame.

[0018] By adopting the above technical solution, the designed telescopic mechanism can drive the support frame to move towards the moving mold side by driving the hydraulic cylinder. The support frame can also drive the fixed mold to separate from the load-bearing base, thereby reducing the friction force when the fixed mold rotates.

[0019] In one specific implementation, the support frame is rotatably connected to a plurality of ball bearings on the side near the bottom wall of the fixed mold, and the ball bearings are rotatably connected to the fixed mold.

[0020] By adopting the above technical solution, the ball bearings can be used to support the fixed mold while converting sliding friction into rolling friction, thereby facilitating the rotation of the fixed mold.

[0021] Secondly, this application provides a molding process for an anti-warping automotive glove box, including... S1: Processing and Mold Installation: Processing to obtain the molding mold, which includes a fixed mold with two cores, a moving mold with two cavities, and a load-bearing base.

S2: Injection molding: After the plastic granules are melted, they are injected into the cavity of the mold in the mold-closing state until it is full. Then the cavity is cooled and shaped. At this time, the moving mold moves back and the glove box stays on the core and separates from the moving mold. S3: Mold rotation and shaping: Rotate the fixed mold so that the core moves the glove box to the bottom of another cavity, close the mold again to cool and shape the glove box, and at the same time, inject a new glove box into the cavity near the injection nozzle. S4: Mold opening and part removal: After mold opening, remove the shaped glove box and repeat step S3.

[0022] By adopting the above technical solution, the fixed mold and the moving mold are installed in their corresponding positions on the injection molding machine. After the moving mold and the fixed mold are closed, a molding or shaping gap is formed between the core and the cavity, which can accommodate the glove box. Then, the molten plastic granules are injected into the cavity of the mold in the closed state until it is full. Then, the cavity is cooled and shaped. At this time, the moving mold retracts, and the glove box stays on the core and separates from the moving mold. Then, the fixed mold is rotated by the rotating unit, so that the core moves the glove box to the bottom of another cavity. The mold is closed again to cool and shape the glove box, while moving it closer to the cavity. The new glove box is injected into the cavity of the injection nozzle. Finally, the mold is opened and the molded glove box is removed. Through this molding process, the molding gap for injection molding or cooling and shaping of glove boxes can be formed after the mold is closed by the fixed mold, moving mold and core. The load-bearing base can provide support for the fixed mold when the mold is closed. The rotating unit can drive the core to move through the fixed mold, so as to realize the simultaneous injection molding of new glove boxes and cooling and shaping of old glove boxes. This improves the injection molding efficiency of automotive glove boxes while improving the molding quality.

[0023] In one specific implementation scheme, in step S3, a rotating unit is used to realize the action of fixing the mold, and the rotating unit includes... A rotary motor is connected to the load-bearing base, and the output shaft of the rotary motor is coaxial with the rotational coincident axis of the two cores; A polygonal rod, one end of which is connected to the output shaft of the rotary motor, and the other end of which passes through the load-bearing base and extends into the fixed mold, and is slidably connected to the fixed mold; A telescopic mechanism is installed on the load-bearing base and can be connected to the fixed mold to drive the fixed mold to move toward or away from the load-bearing base.

[0024] By adopting the above technical solution, the rotation of the fixed mold can be achieved through the cooperation of a rotary motor and a polygonal rod, thereby completing the transfer of the glove box between the two cavities. The telescopic mechanism can separate the fixed mold and the load-bearing base before rotation, thereby reducing the resistance to the rotation of the fixed mold.

[0025] In one specific implementation scheme, in step S3, a lower cooling channel is provided on the fixed mold, the lower cooling channel extends into the core, and a liquid supply unit is connected to the outside of the lower cooling channel. The liquid supply unit is used to input and return coolant into the lower cooling channel.

[0026] By adopting the above technical solution, the core temperature can be controlled, thereby controlling the flowability of the injection molding compound and the cooling speed of the glove box, and improving the molding quality of the automotive glove box.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1.

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] This application discloses a molding process and mold for an anti-warping automotive glove box.

[0040] In a first aspect, embodiments of this application disclose an anti-warping automotive glove box molding die.

[0041] Reference Figures 1-3 A mold for forming an anti-warping automotive glove box includes a fixed mold 1 and a moving mold 3. Two cores 2 are integrally connected to the top wall of the fixed mold 1. The two cores 2 can overlap after rotating around a vertical axis. The moving mold 3 is located above the fixed mold 1. Two cavities 31 are opened on the side of the moving mold 3 closest to the fixed mold 1. After the mold is closed, the cores 2 can extend into the cavities 31, and a forming or shaping gap adapted to the shape and size of the glove box is formed between the cores 2 and the cavities 31. The injection port is opened on the fixed mold 1, and there are two injection ports. The two injection ports are respectively connected to the flow channels on the two cores 2.

[0042] Reference Figure 3 and Figure 4 In order to facilitate the cooling and shaping of another glove box during injection molding, thereby improving the injection molding efficiency of automotive glove boxes, a load-bearing base 4 and a rotating unit 5 are also included. The load-bearing base 4 is located on the side of the fixed mold 1 away from the moving mold 3, and the load-bearing base 4 is used to be fixedly connected to the injection molding machine body. The rotating unit 5 is connected to the fixed mold 1, and the rotating unit 5 is used to drive the fixed mold 1 to rotate around the rotation axis of the two cores 2 on the fixed mold 1.

[0043] Reference Figure 4 and Figure 5 The rotating unit 5 includes a rotating motor 51 and a polygonal rod 52. The body of the rotating motor 51 is bolted to the side of the load-bearing base 4 away from the fixed mold 1. The output shaft of the rotating motor 51 is connected to one end of the polygonal rod 52 through a coupling. The end of the polygonal rod 52 away from the output shaft of the rotating motor 51 passes through the load-bearing base 4 and extends into the fixed mold 1. The polygonal rod 52 is offset from the load-bearing base 4 and is slidably connected to the fixed mold 1. In this application, the cross-sectional shape of the polygonal rod 52 can be triangular, quadrilateral, or pentagonal. Any polygon that does not overlap after rotation is acceptable. In this embodiment, the cross-sectional shape of the polygonal rod 52 is preferably rectangular.

[0044] Reference Figure 4 and Figure 5 To reduce the resistance of the fixed mold 1 rotation, the rotating unit 5 also includes a telescopic mechanism 53. The telescopic mechanism 53 is mounted on the load-bearing base 4 and can be connected to the fixed mold 1 to drive the fixed mold 1 to move toward or away from the load-bearing base 4. The telescopic mechanism 53 includes a support frame 531 and multiple driving hydraulic cylinders 532. The load-bearing base 4 has a receiving cavity 41 for accommodating the support frame 531 on the side near the fixed mold 1, and the support frame 531 is slidably connected to the load-bearing base 4. The polygonal rod 52 is staggered from the support frame 531. The driving hydraulic cylinder 532 is bolted to the load-bearing base 4 and is used to connect to the injection molding machine body. The circumferential direction of the piston rod of the driving hydraulic cylinder 532 is consistent with the axial direction of the output shaft of the rotary motor 51, and the piston rod of the driving hydraulic cylinder 532 is connected to the support frame 531 to drive the support frame 531 to move toward the moving mold 3.

[0045] Reference Figure 4 and Figure 5To further reduce the resistance of the fixed mold 1 rotation, multiple balls 8 are rolled and embedded on the side of the support frame 531 near the bottom wall of the fixed mold 1. The driving hydraulic cylinder 532 can drive the multiple balls 8 to move simultaneously through the support frame 531 until the balls 8 roll and connect with the fixed mold 1. After the mold is opened, the multiple driving hydraulic cylinders 532 move synchronously, causing the support frame 531 to move towards the moving mold 3. While the support frame 531 moves, it drives the multiple balls 8 to move synchronously until the balls 8 abut against the bottom wall of the fixed mold 1, causing the fixed mold 1 to separate from the load-bearing base 4. At this time, the external power supply provides power to the rotary motor 51. The output shaft of the rotary motor 51 drives the fixed mold 1 to rotate through the polygonal rod 52, thereby realizing the position exchange of the two cores 2 and driving the already formed glove box to move for cooling and shaping.

[0046] Reference Figure 6 and Figure 7 In order to control the temperature of the core 2, and thus control the flowability of the injection molding compound and the cooling speed of the glove box, thereby improving the molding quality of the automotive glove box, a lower cooling channel 11 is provided on the fixed mold 1. The lower cooling channel 11 extends into the core 2, and a liquid supply unit is connected to the outside of the lower cooling channel 11. The liquid supply unit is used to input and return coolant into the lower cooling channel 11 as needed. In this application, the liquid supply unit is preferably a commonly used mold temperature controller.

[0047] Reference Figure 6 and Figure 7 In order to further achieve comprehensive temperature control within the two cavities 31, an upper cooling channel 32 is provided on the moving mold 3. The upper cooling channel 32 is arranged around the periphery of the two cavities 31. Two electrically controlled conductive pipes 6 are welded on the moving mold 3. The electrically controlled conductive pipes 6 are vertically arranged. A sliding conductive section for inserting the electrically controlled conductive pipes 6 is formed in the lower cooling channel 11. The electrically controlled conductive pipes 6 are slidably inserted into the fixed mold 1 through the sliding conductive section. The upper cooling channel 32 and the lower cooling channel 11 are connected through the electrically controlled conductive pipes 6.

[0048] Reference Figure 6 and Figure 7 In order to reduce the possibility of coolant leakage through the gap between the electrically controlled conductive pipe 6 and the sliding conductive section during mold closing, at least one rubber sealing ring 7 is coaxially sleeved on the outer periphery of the electrically controlled conductive pipe 6, and the rubber sealing ring 7 is interference-fitted with the inner wall of the sliding conductive section; the electrically controlled conductive pipe 6 can also realize the mold closing guidance and positioning of the fixed mold 1 and the moving mold 3.

[0049] The implementation principle of the anti-warping automotive glove box molding die in this application embodiment is as follows: The fixed mold 1 and the moving mold 3 are installed in their corresponding positions on the injection molding machine. After the moving mold 3 and the fixed mold 1 are closed, a gap is formed between the core 2 and the cavity 31 that can accommodate the glove box. Then, molten plastic granules are injected into the cavity 31 of the mold in the closed state until it is full. Coolant is then introduced and circulated into the upper cooling channel 32 and the lower cooling channel 11 through the liquid supply unit to achieve cooling and shaping treatment in the two cavities 31. At this time, the moving mold 3 retracts, and the glove box remains on the core 2 and separates from the moving mold 3. After the mold opens, multiple drives... The hydraulic cylinder 532 moves synchronously, causing the support frame 531 to move toward the moving mold 3. As the support frame 531 moves, it drives multiple balls 8 to move synchronously until the balls 8 abut against the bottom wall of the fixed mold 1, causing the fixed mold 1 to separate from the load-bearing base 4. At this time, the external power supply provides power to the rotary motor 51. The output shaft of the rotary motor 51 drives the fixed mold 1 to rotate through the polygonal rod 52, thereby realizing the position exchange of the two cores 2 and driving the already formed glove box to move for cooling and shaping. At the same time, a new glove box is injected into the cavity 31 near the injection nozzle. Finally, the mold is opened and the shaped glove box is taken out.

[0050] Secondly, this application discloses an anti-warping automotive glove box molding process.

[0051] A molding process for anti-warping automotive glove boxes, including S1: Processing and molding: Processing to obtain a molding mold, which includes a fixed mold 1 with two cores 2, a moving mold 3 with two cavities 31 and a load-bearing base 4. Then, the fixed mold 1 and the moving mold 3 are installed in the corresponding positions on the injection molding machine. After the moving mold 3 and the fixed mold 1 are closed, a gap is formed between the core 2 and the cavity 31 that can accommodate the glove box. S2: Injection molding: After the plastic granules are melted, they are injected into the cavity 31 of the mold in the mold-closing state until it is full. Then the cavity 31 is cooled and shaped. At this time, the moving mold 3 retracts and the glove box stays on the core 2 and separates from the moving mold 3. S3: Mold rotation and shaping: Rotate the fixed mold 1 so that the core 2 moves the glove box to the cavity 31, which is far away from the injection nozzle of the injection molding machine. Then close the mold again to cool and shape the glove box. At the same time, a new glove box is injected into the cavity 31, which is close to the injection nozzle of the injection molding machine. S4: Mold opening and part removal: After mold opening, remove the shaped glove box and repeat step S3.

[0052] This molding process allows for the formation of two cavities 31 after mold closing, consisting of a fixed mold 1, a moving mold 3, and a core 2, for injection molding or cooling and shaping of glove boxes. A load-bearing base 4 provides support for the fixed mold 1 during mold closing. A rotating unit 5 can drive the core 2 through the fixed mold 1, thereby enabling simultaneous injection molding of new glove boxes and cooling and shaping of old glove boxes. This improves both the molding quality and the injection molding efficiency of automotive glove boxes.

[0053] Furthermore, in step S3, the rotation unit 5 is used to realize the action of the fixed mold 1, and the rotation unit 5 includes... Rotary motor 51, the output shaft of rotary motor 51 is coaxial with the rotational coincident axis of the two cores 2; Polygonal rod 52, one end of which is connected to the output shaft of rotary motor 51, and the other end passes through the load-bearing base 4 and extends into the fixed mold 1, and is slidably connected to the fixed mold 1; Telescopic mechanism 53 is installed on the load-bearing base 4 and can be connected to the fixed mold 1 to drive the fixed mold 1 to move toward or away from the load-bearing base 4.

[0054] The rotation of the fixed mold 1 can be achieved by the cooperation of the rotary motor 51 and the polygonal rod 52, thereby completing the transfer of the glove box between the two cavities 31. The fixed mold 1 and the load-bearing base 4 can be separated before rotation by the telescopic mechanism 53, thereby reducing the resistance to the rotation of the fixed mold 1.

[0055] Furthermore, in step S3, a lower cooling channel 11 is provided on the fixed mold 1. The lower cooling channel 11 extends into the core 2, and a liquid supply unit is connected to the outside of the lower cooling channel 11. The liquid supply unit is used to input and return coolant into the lower cooling channel 11. This can realize the control of the temperature of the core 2, thereby realizing the control of the flowability of the injection molding material and the cooling speed of the glove box, and improving the molding quality of the automotive glove box.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
