[0012] The present invention provides an injection molding mold for a chip tray. It has the following beneficial effects:

[0013] 1. For this injection molding mold for a chip tray, a dredging mechanism is provided. When plastic particles move downward under the action of gravity, a bridging phenomenon may occur at certain positions, hindering the smooth falling of the particles. The stirring rotation of the dredging rod can break this bridging structure, enabling the particles to continue to flow downward and ensuring the smoothness of feeding. As the particles are continuously conveyed, some plastic particles may adhere to the wall of the feeding cylinder, and when accumulated to a certain extent, it will also affect feeding.

[0014] 2. For this injection molding mold for a chip tray, a buffer component is provided. Before the mold closing and injection molding work, when the moving mold component drives the moving template to move towards the fixed mold component, the moving mold component drives the moving outer shell to move towards the fixed outer shell through the sliding block, so that the moving outer shell drives the contact rod to move towards the fixed outer shell through the limit block, and then the roller contacts the inner wall of the fixed outer shell.

[0015] 3. For this injection molding mold for a chip tray, a buffer assembly is provided. The buffer rod made of rubber has good elasticity and flexibility. When the chip tray drops and contacts it, it can effectively absorb and disperse part of the impact force, reduce the instantaneous impact force received by the chip tray, and avoid cracks, breakage or deformation of the chip tray due to excessive impact force, thus ensuring the integrity and quality of the chip tray.

[0016] 4. For this injection molding mold for a chip tray, a contact mechanism is provided. By cleaning the inner walls of the fixed outer shell and the moving outer shell during the mold closing operation, it is avoided that when the injection molded chip tray passes through the feeding for a long time, impurities and debris on the chip tray will splash and adhere to the inner walls of the fixed outer shell and the moving outer shell, and then adhere to the chip tray during the subsequent discharging of the injection molded chip tray, thus ensuring the cleanliness of the surface of the chip tray during discharging.

[0035] When the plastic particles are continuously fed into the upper barrel 76, the plastic particles continuously fed into the upper barrel 76 will continuously impact the tilting blade 753. This continuous impact force can provide continuous power for the rotation of the tilting blade 753, so that the tilting blade 753 drives the rotating shaft 752 to rotate in the upper barrel 76, so that the rotating shaft 752 drives the dredging rod 755 to stir and rotate the plastic particles through the connecting plates 754 on the upper and lower sides;

[0036] See also Figures 5-9 , the present invention provides a technical solution:

[0037] See also Figures 5-7 The buffer component 6 includes a feed opening 61, a clearance groove 62 and a fixed shell 69. The feed opening 61 is opened in the middle of the top of the injection molding machine 1, and the clearance groove 62 is opened at the top of the injection molding machine 1.

The side of the sliding rod 65 is slidably connected with the inner side of the sliding block 64. The sliding rod 65 is arranged below the guide rod 63, and the sliding rod 65 is sleeved with a first A spring 66, one end of the first spring 66 is fixedly connected to the side of the sliding block 64, the other end of the first spring 66 is fixedly connected to the inner wall of the give way groove 62, the bottom of the sliding block 64 is fixedly connected to a movable housing 67, the top of the movable housing 67 is slidably connected to the inner side of the injection molding machine 1, the top of the fixed housing 69 is fixedly connected to the inner side of the injection molding machine 1, the inner side of the fixed housing 69 and the inner side of the movable housing 67 are both fixedly connected to a contact mechanism 68, and the contact mechanism 68 on the inner side of the fixed housing 69 and the contact mechanism 68 on the inner side of the movable housing 67 are cross-arranged;

[0038] When the movable mold part 2 is moving to open the mold, the movable mold part 2 is moved on the guide rod 63 and the slide rod 65 through the sliding block 64, and the first spring 66 is squeezed at the same time, driving the movable shell 67 to separate from the fixed shell 69, so that the movable shell 67 drives the contact mechanism 68 to separate from the inner wall of the fixed shell 69, so that when the molded chip tray is unloaded, the contact mechanism 68 can buffer the chip tray that falls off the mold, thereby preventing the chip tray from being collided and damaged when it falls;

[0039] Please refer to Figure 8 , the contact mechanism 68 includes a contact rod 681 and a limit block 683. One end of the contact rod 681 close to the limit block 683 is fixedly connected with a rotating rod 682. One side of the contact rod 681 close to the limit block 683 is rotatably connected with a connecting rod 684. The side surface of the limit block 683 is fixedly connected with the inner wall of the moving housing 67. One side of the limit block 683 close to the contact rod 681 is rotatably connected with the side surface of the rotating rod 682. The inner side of the limit block 683 is fixedly connected with a sliding shaft 686. The side surface of the sliding shaft 686 is slidably connected with a slider 685. The side surface of the slider 685 is slidably connected with the inner side of the limit block 683. The side surface of the slider 685 is rotatably connected with one end of the connecting rod 684 far from the contact rod 681. A second spring 687 is sleeved on the sliding shaft 686. One end of the second spring 687 is fixedly connected with the side surface of the slider 685. The other end of the second spring 687 is fixedly connected with the inner wall of the limit block 683. One end of the contact rod 681 far from the rotating rod 682 is fixedly connected with a contact plate 688. One side of the contact plate 688 far from the limit block 683 is rotatably connected with a roller 6810. One side of the contact plate 688 close to the roller 6810 is fixedly connected with a wiping plate 6811. One side of the wiping plate 6811 far from the contact plate 688 is in contact with the side surface of the roller 6810. One side of the contact plate 688 far from the roller 6810 is fixedly connected with a buffer assembly 689;

[0040] Before the mold closing and injection molding work is carried out, when the moving mold part 2 drives the moving template to move towards the fixed mold part 3, the moving mold part 2 drives the moving housing 67 to move towards the fixed housing 69 through the sliding block 64, so that the moving housing 67 drives the contact rod 681 to move towards the fixed housing 69 through the limit block 683, so that the roller 6810 is in contact with the inner wall of the fixed housing 69;

[0041] When the moving mold part 2 continues to carry out the mold closing work, the roller 6810 moves on the inner wall of the fixed housing 69, so that the roller 6810 moves in contact on the inner wall of the fixed housing 69. At the same time, the contact rod 681 is subjected to a squeezing force, so that the contact rod 681 deflects on the limit block 683 through the rotating rod 682. At the same time, the connecting rod 684 pulls the slider 685 and the second spring 687 to move on the sliding shaft 686. Furthermore, when the fixed mold part 3 and the moving mold part 2 are closed, the roller 6810 can be driven by the contact rod 681 to move and clean on the inner wall of the fixed housing 69;

[0042] Meanwhile, when the roller 6810 moves in contact with the inner wall of the fixed housing 69 and rotates, it comes into contact with the wiping plate 6811 at the same time. As a result, the wiping plate 6811 can clean the side surface of the roller 6810, thus preventing a large amount of impurities from adhering to the roller 6810 during the cleaning of the fixed housing 69 by the roller 6810, which may interfere with the normal rotation and cleaning work of the roller 6810.

[0043] Please refer to Figure 9 , the buffer assembly 689 includes a square plate 6891 and a buffer plate 6894. The inner side of the square plate 6891 is slidably connected to the side surface of the buffer plate 6894. The side of the buffer plate 6894 away from the square plate 6891 is fixedly connected to the side of the contact plate 688 away from the wiping plate 6811. The other side of the buffer plate 6894 is fixedly connected to a round rod 6895. The end of the round rod 6895 away from the buffer plate 6894 is slidably connected to the inner side of the square plate 6891. A third spring 6896 is sleeved on the round rod 6895. One end of the third spring 6896 is fixedly connected to the side of the buffer plate 6894 close to the round rod 6895, and the other end of the third spring 6896 is fixedly connected to the side of the square plate 6891 close to the round rod 6895. A buffer rod 6892 is rotatably connected to the side of the square plate 6891 away from the round rod 6895, and annular grooves 6893 are formed on both sides of the buffer rod 6892.

[0044] When the chip tray after injection molding falls through the blanking port 61, it comes into contact with and impacts the buffer rods 6892 on both sides. At the same time, the buffer rods 6892 are made of rubber. When the impact force between the chip tray and the buffer rods 6892 is too large during the fall of the chip tray, the square plate 6891 drives the buffer rod 6892 to move towards the buffer plate 6894 through the round rod 6895, and at the same time, the third spring 6896 is compressed by the square plate 6891, thus preventing the extrusion force between the buffer rod 6892 and the chip tray from being too large.

[0045] Specific working process:

[0046] The oil cylinder in the moving die part 2 drives the moving template to move towards the fixed die part 3. When the moving die and the fixed die are completely closed, a closed cavity is formed, and its shape and size are exactly the same as those of the chip tray.

[0047] The plastic particles are heated and melted in the extrusion part 7 to form a plastic melt with a certain fluidity. The extrusion part 7 enters the cavity, and under the action of the injection pressure, the plastic melt fills the entire cavity and starts to form the chip tray.

[0048] When feeding plastic particles, a large amount of plastic particles are continuously fed into the extrusion housing 71 through the feeding cylinder 76. The plastic particles entering the feeding cylinder 76 impact with the dredging mechanism 75, thus avoiding the blockage of plastic particles in the feeding cylinder 76. At the same time, when the plastic particles enter the extrusion housing 71, the motor 74 is turned on, and the output end of the motor 74 drives the spiral blade 73 to rotate in the extrusion housing 71;

[0049] The plastic particles in the extrusion housing 71 are gradually heated and melted by the heating of the heating component 4 and the rotational stirring action of the spiral blade 73 to form a plastic melt with good fluidity;

[0050] When the plastic melt reaches the specified quantity and temperature, the plastic melt is extruded from the discharge end of the extrusion housing 71, passes through the pouring mechanism 72 and enters the cavity of the mold, enabling the plastic melt to quickly and evenly fill the cavity;

[0051] When plastic particles are continuously fed into the feeding cylinder 76, the plastic particles continuously fed into the feeding cylinder 76 will continuously impact the inclined blade 753. This continuous impact force can provide continuous power for the rotation of the inclined blade 753, causing the inclined blade 753 to drive the rotating shaft 752 to rotate in the feeding cylinder 76. As a result, the rotating shaft 752 drives the dredging rod 755 to perform stirring and rotating work on the plastic particles through the connecting plates 754 on the upper and lower sides;

[0052] The rotation of the inclined blade 753 and the dredging rod 755 has a certain pushing effect on the plastic particles, which can provide additional power for the particles on the basis of gravity, accelerating the downward movement speed of the particles, thereby improving the feeding efficiency and meeting the requirements for the material supply speed in the production process;

[0053] After the plastic melt fills the cavity, a certain pressure is continuously maintained to enable the plastic melt to perform compensatory shrinkage under the action of the pressure to compensate for the volume change caused by the cooling shrinkage of the plastic and ensure the dimensional accuracy and surface quality of the chip tray;

[0054] After the pressure holding is completed, the cooling system starts to work, and the heat in the mold is removed by circulating cooling water, enabling the plastic melt to quickly cool and solidify in the cavity to form the final shape of the chip tray;

[0055] After cooling is completed, the oil cylinder in the moving die part 2 drives the moving template to move backward to open the mold. At this time, through the ejection device in the fixed die part 3, the formed chip tray is ejected from the core to complete the demolding process;

[0056] The demolded chip tray falls onto the conveying part 5 through the buffer part 6, and thus the conveying part 5 performs the feeding and conveying work on the formed chip tray;

[0057] When the moving die part 2 performs the opening die movement operation, the moving die part 2 moves through the sliding block 64 on the guide rod 63 and the slide rod 65, and at the same time squeezes the first spring 66, driving the moving housing 67 to disengage from the fixed housing 69, so that the moving housing 67 drives the contact mechanism 68 to disengage from the inner wall of the fixed housing 69. When the formed chip tray is unloaded, the contact mechanism 68 can buffer the dropped and demolded chip carriers, thus avoiding the phenomenon of collision and breakage of the chip carriers when they fall;

[0058] Before the mold closing and injection molding operation, when the moving die part 2 drives the moving template to move towards the fixed die part 3, the moving die part 2 drives the moving housing 67 to move towards the fixed housing 69 through the sliding block 64, so that the moving housing 67 drives the contact rod 681 to move towards the fixed housing 69 through the limit block 683, so that the roller 6810 contacts the inner wall of the fixed housing 69;

[0059] When the moving die part 2 continues to perform the moving and mold closing operation, the roller 6810 moves on the inner wall of the fixed housing 69, so that the roller 6810 moves in contact with the inner wall of the fixed housing 69. At the same time, the contact rod 681 is subjected to a squeezing force, so that the contact rod 681 deflects on the limit block 683 through the rotating rod 682. At the same time, the connecting rod 684 pulls the slider 685 and the second spring 687 to move on the sliding shaft 686. When the fixed die part 3 and the moving die part 2 are closed, the roller 6810 can be driven by the contact rod 681 to move and clean on the inner wall of the fixed housing 69;

[0060] At the same time, when the roller 6810 moves in contact with the inner wall of the fixed housing 69 and the roller 6810 rotates, it contacts the wiping plate 6811 at the same time, so that the wiping plate 6811 can clean the side surface of the roller 6810, thus avoiding a large amount of impurities adhering to the roller 6810 when the roller 6810 cleans the fixed housing 69, which interferes with the normal rotation and cleaning work of the roller 6810;

[0061] Since the contact mechanism 68 is cross - arranged inside the fixed housing 69 and inside the moving housing 67, when the contact mechanism 68 on the moving housing 67 cleans the inside of the fixed housing 69, the contact mechanism 68 on the inside of the fixed housing 69 can simultaneously clean the inside of the moving housing 67;

[0062] By cleaning the inner walls of the fixed housing 69 and the moving housing 67 during the mold clamping operation, it is possible to prevent impurities and debris on the chip tray from splashing and adhering to the inner walls of the fixed housing 69 and the moving housing 67 during long-term feeding, and then adhering to the chip tray during the subsequent discharging of the injection-molded chip tray, thus ensuring the cleanliness of the surface of the chip tray during discharging;

[0063] At the same time, when the moving die component 2 performs the mold opening and moving operation, the moving die component 2 moves on the guide rod 63 and the slide rod 65 through the slider 64, driving the moving housing 67 away from the fixed housing 69, so that the moving housing 67 drives the contact rod 681 to move away from the fixed housing 69, thereby adjusting the distance between the contact rods 681 on the fixed housing 69 and the moving housing 67. When the injection-molded chip tray drops through the feeding port 61, the buffer assembly 689 on the fixed housing 69 and the moving housing 67 can buffer the dropped chip tray;

[0064] When the injection-molded chip tray drops through the feeding port 61, the chip tray contacts and impacts the buffer rods 6892 on both sides. At the same time, the buffer rods 6892 are made of rubber. When the impact force between the chip tray and the buffer rods 6892 is too large during the dropping of the chip tray, the square plate 6891 drives the buffer rod 6892 to move towards the buffer plate 6894 through the round rod 6895, and at the same time, the square plate 6891 squeezes the third spring 6896, thus preventing the excessive extrusion force between the buffer rod 6892 and the chip tray;

[0065] The buffering effect of the buffer rod 6892 on the chip tray can effectively control the movement state of the chip tray during dropping, preventing it from splashing or bouncing out of the conveying component 5 due to excessive impact force.

[0066] Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art without special instructions and limitations.
