A drive component is fixedly connected to one side of one of the baffles, and the drive component is connected to the drive rod.

[0009] Furthermore, the distance between the clearance opening and the top surface of the conveyor belt is greater than the maximum height of the car door panel.

[0010] Furthermore, the fixing part includes a vacuum generator fixedly connected to the top of the fixing plate, and a plurality of vacuum suction cups fixedly connected to the bottom of the fixing plate, the vacuum suction cups being connected to the vacuum generator through pipes.

[0011] In summary, this utility model has at least one of the following beneficial technical effects:

[0012] This type of injection molding mold for automotive door panels involves an electric push rod that lifts a fixed plate when the front and rear molds separate. Then, a drive unit rotates the fixed plate, causing a vacuum suction cup to face the automotive door panel. The electric push rod then extends, causing the vacuum suction cup to adhere to the automotive door panel. A vacuum generator then activates to attract the automotive door panel. The electric push rod retracts, and the drive unit reverses, leveling the automotive door panel. Finally, the electric push rod extends again, bringing the automotive door panel close to the conveyor belt. The vacuum generator stops, and the automotive door panel automatically falls onto the conveyor belt and is transported away.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example:

[0020] Reference Figures 1 to 3 This utility model discloses an injection molding die for an automotive door panel, comprising a base plate 1 and two side plates 2 fixedly connected to the top of the base plate 1 near both sides. One side plate 2 is fixedly connected to a rear mold 3 on one side, and the other side plate 2 is fixedly connected to a plurality of hydraulic rods 4 on the side near the rear mold 3. The output ends of the plurality of hydraulic rods 4 are fixedly connected to a front mold 5. Baffles 6 are fixedly connected to both sides of the top of the base plate 1 near the width direction of the base plate 1. A clearance opening 7 is provided on the lower half of one side of the baffle 6. A conveyor belt 8 is provided above the base plate 1. The conveyor belt 8 passes through the two clearance openings 7 and is located below the front mold 5 and the rear mold 3. A fixing plate 9 is provided above the conveyor belt 8 and is located below the front mold 5 and the rear mold 3. A fixing part 10 is provided on one side of the fixing plate 9, and an adjusting part 11 is provided above the fixing plate 9.

[0021] In this embodiment, during the injection molding of the car door panel, the hydraulic rod 4 first operates to move the front mold 5 to fit against the rear mold 3. Then, liquid injection fluid is added to the injection cavity of the front mold 5 under high pressure. After it has formed and cooled, the hydraulic rod 4 retracts, moving the front mold 5 away from the rear mold 3, leaving the car door panel inside the rear mold 3 (e.g., ...). Figure 1 (As shown). At this time, the fixing plate 9 is located below the front mold 5 and the rear mold 3, and will not obstruct the movement of the front mold 5. The conveyor belt 8 is existing technology and will not be described in detail here. The conveyor belt 8 is in working condition.

[0022] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the adjustment part 11 includes a rotating rod 111 that is rotatably inserted through one side of the baffle 6. A fixing block 112 is fixedly connected to one end of the rotating rod 111 located between the two baffles 6. An electric push rod 113 is fixedly connected to one side of the fixing block 112. The output ends of the two electric push rods 113 are fixedly connected to the top surface of the fixing plate 9. A rotating part 114 is provided above the rotating rod 111.

[0023] In this embodiment, one side of the fixing block 112 is attached to the side wall of the corresponding baffle 6, and the fixing block 112 does not extend between the front mold 5 and the rear mold 3, so it will not hinder the movement of the front mold 5.

[0024] After the current mold 5 moves away from the rear mold 3, the electric push rod 113 retracts, causing the fixing plate 9 to move upward, preventing the fixing plate 9 from colliding with the rear mold 3 when it rotates.

[0025] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the rotating part 114 includes a drive rod 115 rotatably connected between two baffles 6. The drive rod 115 is located above the front mold 5 and the rear mold 3, and the drive rod 115 is connected to both rotating rods 111 via a belt. A drive component 116 is fixedly connected to one side of one of the baffles 6, and the drive component 116 is connected to the drive rod 115 via a transmission connection.

[0026] In this embodiment, the drive rod 115 is located above the front mold 5 and the rear mold 3, so the drive rod 115 will not obstruct the movement of the front mold 5. The drive component 116 includes a servo motor fixedly connected to the side wall of the baffle 6. The output end of the servo motor is connected to the drive rod 115 through a gear set. The servo motor drives the drive rod 115 to rotate, and the drive rod 115 drives the rotating rod 111 to rotate through a belt. Each time the servo motor works, it drives the rotating rod 111 to rotate 90°.

[0027] After the electric push rod 113 drives the fixed plate 9 to move upward to the center height of the upper mold, the drive component 116 works to drive the rotating rod 111 to rotate 90°, so that the fixed plate 9 rotates 90°. Then the electric push rod 113 extends, driving the fixed plate 9 to move towards the rear mold 3, and finally fits the car door panel.

[0028] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the distance between the clearance 7 and the top surface of the conveyor belt 8 is greater than the maximum height of the car door panel.

[0029] In this embodiment, when the car door panel falls onto the conveyor belt 8, the conveyor belt 8 can drive the car door panel through the clearance opening 7, thereby realizing the automatic transfer of the car door panel.

[0030] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the fixing part 10 includes a vacuum generator 101 fixedly connected to the top of the fixing plate 9, and a plurality of vacuum suction cups 102 fixedly connected to the bottom of the fixing plate 9. The vacuum suction cups 102 are connected to the vacuum generator 101 through pipes.

[0031] In this embodiment, when the fixing plate 9 is attached to the car door panel, the vacuum suction cup 102 also attaches to the car door panel. The vacuum generator 101 operates, causing the vacuum suction cup 102 to adhere to the car door panel. Then, the electric push rod 113 retracts, causing the car door panel to detach from the rear mold 3. Next, the drive component 116 reverses, causing the fixing plate 9 to return to a horizontal state. Then, the electric push rod 113 extends, causing the fixing plate 9 to return to its initial position. The car door panel also approaches the top surface of the conveyor belt 8. At this time, the distance between the car door panel and the top of the conveyor belt 8 is small, so the car door panel will not bounce when it falls. Finally, the vacuum generator 101 stops, and the car door panel falls onto the conveyor belt 8 and is transported away by the conveyor belt 8, thus realizing the automatic demolding and transportation of the car door panel.

[0032] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
