Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a composite material injection molding mold for automotive parts. Background Technology

[0002] Automobiles are currently the most common means of transportation, and auto parts are the various units that make up a car and the products that serve the car. There are many types of auto parts, and composite materials have entered the manufacturing industry. As people's living standards improve, people's consumption of cars is also increasing, and the market for auto parts is becoming larger and larger. Injection molds are usually used in the processing and production of some smaller auto parts.

[0003] In traditional injection molding, the raw material is injected into the mold and then removed after cooling.

[0004] Based on the aforementioned technologies, the applicant believes that air bubbles will exist inside the mold body and in the cooled parts, which will affect the quality of the automotive parts. Existing injection molds lack a mechanism for mixing the liquid inside the mold during use. In response to the above problems, we have launched a composite material injection mold for automotive parts production. Utility Model Content

[0005] This utility model discloses a composite material injection molding mold for automotive parts, aiming to solve the problem that air bubbles exist in the mold body and in the parts after cooling, which will affect the quality of automotive parts. Existing injection molds lack a mechanism for shaking the liquid inside the mold during use.

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

[0007] A composite material injection molding mold for automotive parts includes a base. Support columns are symmetrically fixedly connected to both sides of the top of the base. A top cover is fixedly connected to the top of each support column. A molding die is slidably connected to the top of the base. The top of the molding die has symmetrically provided injection ports for injecting different injection molding materials. A rocking mechanism is provided on the top of the base. The rocking mechanism includes a rocking component, a power component, and a buffer component, which cooperate with each other. The rocking component includes clearance grooves symmetrically located on both sides of the top cover. Fixed seats are symmetrically fixedly connected to both sides of the top cover. Racks are slidably connected inside the two fixed seats on the same side. Rotating shafts are rotatably connected to both sides of the top cover. Half gears are fixedly connected to the outer sides of the two rotating shafts, and the half gears mesh with the racks. Connecting plates are fixedly connected to both sides of the molding die, and the connecting plates are fixedly connected to the bottom of the racks.

[0008] The shaking mechanism accelerates material fusion, allowing the composite material to quickly reach the interior of the molding die, preventing air bubbles and significantly improving the production quality of automotive parts. It has a simple structure and strong practicality.

[0009] In a preferred embodiment, the power assembly includes a motor fixedly connected to the top of the top cover. A rotating shaft is rotatably connected inside the top cover. The output end of the motor extends into the interior of the top cover and is fixedly connected to a gear disk. A bevel gear is fixedly connected to the outer side of the rotating shaft, and the bevel gear and the gear disk mesh with each other. Both ends of the rotating shaft extend to the outer side of the top cover and are fixedly connected to rotating disks. A sliding frame is fixedly connected to the top of each of the two half gears. A sliding column is slidably connected inside each of the two sliding frames, and the sliding column and the rotating disk are fixedly connected.

[0010] The motor drives the gear plate and bevel gear, which in turn rotate the rotating shaft and the rotating disk. The circular motion is then converted into the reciprocating oscillation of the half gear through the sliding frame and sliding column. The structure is compact and the transmission is efficient. The meshing of the rack and the half gear ensures smooth shaking, avoids jamming, and improves production stability.

[0011] In a preferred embodiment, the buffer assembly includes a sliding frame fixedly connected to the top of the base. The bottom of the molding die is symmetrically provided with T-shaped grooves, which cooperate with the sliding frame. Sliding rods are symmetrically slidably connected to both sides of the sliding frame. Rubber balls are fixedly connected to the ends of the sliding rods that are close to each other. Limiting plates are fixedly connected to the other ends of the sliding rods. Buffer springs are sleeved on the outer side of the sliding rods.

[0012] The buffer assembly uses the cooperation of the sliding frame and the T-slot to limit the movement range of the molding die. The sliding rod, rubber ball and buffer spring absorb the impact force during shaking and reduce die wear. The limit plate prevents the sliding rod from falling out, ensuring a long-lasting and reliable buffering effect and extending the service life of the equipment.

[0013] In a preferred embodiment, the base has equidistant ventilation slots inside, and a heat dissipation cavity is formed at the bottom of the base. The heat dissipation cavity and the ventilation slots are used in conjunction with each other.

[0014] The ventilation slots and heat dissipation chambers form airflow channels, accelerating the dissipation of heat inside the base, preventing mold deformation or material performance degradation caused by high temperatures, and ensuring injection molding accuracy and product consistency.

[0015] In a preferred embodiment, a protective cover is fixedly connected to the outside of the motor, and heat dissipation holes are equidistantly opened on the top of the protective cover.

[0016] The protective cover protects the motor from dust and splashes, while the heat dissipation holes enhance the motor's heat dissipation efficiency, preventing overheating shutdowns and improving continuous operation capability.

[0017] In a preferred embodiment, a controller is fixedly connected to the front of the base, and the motor is electrically connected to the controller.

[0018] The controller centrally regulates the motor's operating parameters, enabling precise control of the shaking frequency and intensity, adapting to the process requirements of different materials, and improving production flexibility and automation.

[0019] The composite material injection mold for automotive parts provided by this utility model has the following advantages:

[0020] Firstly, the shaking mechanism accelerates material fusion, allowing the composite material to quickly reach the interior of the molding die, preventing air bubbles and significantly improving the production quality of automotive parts. It has a simple structure and strong practicality.

[0021] Secondly, the ventilation slots and heat dissipation chambers form airflow channels, accelerating the dissipation of heat inside the base, preventing mold deformation or material performance degradation caused by high temperatures, ensuring injection molding accuracy and product consistency. The protective cover protects the motor from dust and splashes, while the heat dissipation holes enhance the motor's heat dissipation efficiency, preventing overheating shutdowns and improving continuous operation capabilities. The controller centrally regulates the motor's operating parameters, achieving precise control of the shaking frequency and intensity, adapting to the process requirements of different materials, and improving production flexibility and automation levels.

[0029] The composite material injection molding mold for automotive parts disclosed in this utility model is mainly used in automotive parts production.

[0030] Reference Figure 1 - Figure 5A composite material injection molding mold for automotive parts includes a base 1. Support columns 2 are symmetrically fixedly connected to both sides of the top of the base 1. A top cover 3 is fixedly connected to the top of the support columns 2. A molding mold 4 is slidably connected to the top of the base 1. The top of the molding mold 4 is symmetrically provided with injection ports 5 for injecting different injection molding materials. A rocking mechanism is provided on the top of the base 1. The rocking mechanism includes a rocking component, a power component, and a buffer component, which work together. The rocking component includes a clearance groove 10, which is symmetrically opened on both sides of the top cover 3. Fixed seats 69 are symmetrically fixedly connected to both sides of the top cover 3. A rack 610 is slidably connected inside the two fixed seats 69 on the same side. Rotating shafts 66 are rotatably connected to both sides of the top cover 3. Half gears 611 are fixedly connected to the outer sides of the two rotating shafts 66, and the half gears 611 and racks 610 are meshed together. Connecting plates 612 are fixedly connected to both sides of the molding mold 4, and the connecting plates 612 are fixedly connected to the bottom of the racks 610. The power assembly includes a motor 61, which is fixedly connected to the top of the top cover 3. A rotating shaft 63 is rotatably connected inside the top cover 3. The output end of the motor 61 extends into the interior of the top cover 3 and is fixedly connected to a gear disk 62. A bevel gear 64 is fixedly connected to the outside of the rotating shaft 63. The bevel gear 64 and the gear disk 62 are meshed together. Both ends of the rotating shaft 63 extend to the outside of the top cover 3 and are fixedly connected to a rotating disk 65. A sliding frame 67 is fixedly connected to the top of each of the two half gears 611. A sliding column 68 is slidably connected inside each of the two sliding frames 67. The sliding column 68 and the rotating disk 65 are fixedly connected. The buffer assembly includes a sliding frame 71, which is fixedly connected to the top of the base 1. The bottom of the molding mold 4 is symmetrically provided with T-shaped grooves 76, which are used in conjunction with the sliding frame 71. Sliding rods 72 are symmetrically slidably connected to both sides of the sliding frame 71. Rubber balls 73 are fixedly connected to the ends of the sliding rods 72 that are close to each other. Limiting plates 75 are fixedly connected to the other ends of the sliding rods 72. Buffer springs 74 are sleeved on the outer side of the sliding rods 72.

[0031] In this embodiment: During injection molding, the raw material of the composite material is first injected into the mold 4 through the injection port 5. Then, the motor 61 is started. The output end of the motor 61 rotates, driving the gear plate 62 and bevel gear 64 to drive the rotating shaft 63 to rotate, which in turn drives the rotating disk 65 to rotate. The sliding column 68 slides in the sliding frame 67, causing the half gear 611 to swing back and forth and mesh with the rack 610, pushing the mold 4 to shake left and right, promoting material mixing. The rubber ball 73 and the buffer spring 74 of the buffer component absorb the vibration. At the same time, the rubber ball 73 can collide with the mold 4. Through the set shaking mechanism, the material fusion can be accelerated, allowing the composite material to quickly reach the interior of the mold 4, avoiding the formation of air bubbles, greatly improving the production quality of automotive parts. The structure is simple and highly practical.

[0032] In the above technical solution, considering that air bubbles may exist inside the mold body and in the cooled parts, which will affect the quality of automotive parts, and that existing injection molds lack a mechanism for mixing the liquid inside the mold, the following specific operation is performed to solve this problem:

[0033] Reference Figure 1 - Figure 5 In a preferred embodiment, the base 1 has equidistant ventilation slots 8 inside, and a heat dissipation cavity 9 at the bottom of the base 1. The heat dissipation cavity 9 and the ventilation slots 8 cooperate with each other. A protective cover 11 is fixedly connected to the outside of the motor 61, and heat dissipation holes 12 are equidistantly opened on the top of the protective cover 11. A controller 13 is fixedly connected to the front of the base 1, and the motor 61 is electrically connected to the controller 13.

[0034] In this embodiment: the ventilation slot 8 and the heat dissipation cavity 9 form an airflow channel, which accelerates the dissipation of heat inside the base 1, avoids mold deformation or material performance degradation caused by high temperature, and ensures injection molding accuracy and product consistency. The protective cover 11 protects the motor 61 from dust and splashes. The heat dissipation hole 12 enhances the heat dissipation efficiency of the motor 61, avoids overheating shutdown, and improves continuous operation capability. The controller 13 centrally regulates the operating parameters of the motor 61 to achieve precise control of the shaking frequency and intensity, adapt to the process requirements of different materials, and improve production flexibility and automation level.

[0035] Working principle: During injection molding, the raw material of the composite material is first injected into the mold 4 through the injection port 5. Then, the motor 61 is started. The output end of the motor 61 rotates, driving the gear plate 62 and bevel gear 64 to drive the rotating shaft 63 to rotate, which in turn drives the rotating disk 65 to rotate. The sliding column 68 slides in the sliding frame 67, causing the half gear 611 to swing back and forth and mesh with the rack 610, pushing the mold 4 to shake left and right, promoting material mixing. The rubber ball 73 and the buffer spring 74 of the buffer component absorb the vibration. At the same time, the rubber ball 73 can collide with the mold 4 to accelerate material fusion and avoid the formation of air bubbles. The ventilation groove 8 and the heat dissipation cavity 9 assist in cooling. The controller 13 controls the shaking parameters, and finally achieves uniform molding of the composite material.
