Description

Technical Field

[0001] This invention relates to the field of seat molding technology, specifically a seat back molding equipment and its molding method. Background Technology

[0002] A chair is a piece of furniture or equipment that provides a place for people to sit and rest. Different types of chairs have different designs and functions to meet people's needs in various occasions. The chair back can provide support for our back and waist, making us sit more comfortably. A good chair back should have appropriate firmness and angle to conform to the curves of the human body and reduce back pressure. Common molding methods for chair backs include injection molding, stamping, solid wood processing, and soft filling.

[0003] Patent No. CN202022890165.4 proposes a seat back panel mold. By setting up the main body of the equipment, the user controls the operation of the positioning component. The lower positioning component works with the upper positioning component to position the lower and upper modules respectively. The electric drive cylinder is used to achieve higher positioning accuracy and faster speed, preventing gaps and offsets between the upper and lower molds. However, this patent can only manually load and unload materials and cannot automatically add metal mesh for fusion molding, resulting in low molding efficiency.

[0004] Therefore, the present invention provides a seat back forming device and a forming method to solve the above problems. Summary of the Invention

[0015] To better achieve the objectives of this invention, this invention also provides a method for using a seat back forming device, comprising the following steps:

[0016] Step 1: Start the first cylinder. The first cylinder retracts, causing the first sliding bracket to move downwards. The downward movement of the first sliding bracket causes the needle gripper to move downwards. Start the needle gripper. The needle gripper starts to adsorb the soft material. Start the first cylinder. The first cylinder extends, causing the first sliding bracket to move upwards. The upward movement of the first sliding bracket causes the needle gripper to move upwards.

[0017] Step 2: Start the electric linear module. The electric linear module starts and moves the moving frame to the right to the maximum range of the electric linear module. Turn off the electric linear module and start the needle gripper. The needle gripper starts and puts down the soft material. Start the injection port and inject the raw material into the soft material. Start the first electric telescopic rod. The first electric telescopic rod shortens and moves the second sliding bracket downward. The second sliding bracket moves downward and moves the rotating clamp downward. Start the rotating clamp. The drive motor rotates and drives the motor gear to rotate. The motor gear rotates and drives the drive gear to rotate. The drive gear rotates and moves the moving rod on the fixed shaft towards the center of the drive gear shaft to hold the metal mesh.

[0018] Step 3: Start the electric linear module. The start of the electric linear module will move the moving frame to the left to the minimum range of the electric linear module. Start the rotating clamp. The drive motor will rotate, which will drive the motor gear to rotate. The rotation of the motor gear will drive the drive gear to rotate. The rotation of the drive gear will drive the moving rod to move away from the axis of the drive gear on the fixed shaft, and lower the metal mesh clamp.

[0019] Step 4: Start the deceleration self-locking motor. The rotating bracket rotates, causing the upper mold to move towards the lower mold. Start the second electric telescopic rod. The second electric telescopic rod extends, causing the fixed lock to rotate, so that the opening of the fixed lock is tightly against the locking shaft, thereby locking the upper and lower molds. Start the second cylinder. The second cylinder starts, causing the lifting platform to move upward, causing the lower mold to press against the upper mold. Start the second cylinder. The second cylinder starts, causing the lifting platform to move downward. At this time, repeat Step 1. At the same time, start the second electric telescopic rod. The second electric telescopic rod shortens, causing the fixed lock to rotate, so that the opening of the fixed lock is away from the locking shaft. Start the deceleration self-locking motor. The rotating bracket rotates, causing the upper mold to move away from the lower mold. Take out the finished product and start the next product forming.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention utilizes a synchronous loading and unloading device. An electric linear module drives the soft material loading mechanism and the metal mesh loading mechanism to move simultaneously. The metal mesh is loaded while the soft material and injection material are being unloaded. The soft material is loaded while the metal mesh is being formed, reducing loading waiting time and improving forming efficiency. A drive motor rotates the drive gear, which in turn moves the moving rods. The moving rods insert into the gaps in the metal mesh and move closer together to clamp the mesh. This allows the device to clamp metal meshes of multiple sizes, reducing manual labor and improving production efficiency. Attached Figure Description

The drive gear (75) rotates and drives the moving rod (74) to move towards the axis of the drive gear (75) on the fixed shaft (73) to hold the metal mesh. Step 3: Start the electric linear module (61). The electric linear module (61) starts and drives the moving frame (63) to move to the left to the minimum range of the electric linear module (61). Start the rotating clamp (7). The drive motor (72) rotates and drives the motor gear (76) to rotate. The motor gear (76) rotates and drives the drive gear (75) to rotate. The drive gear (75) rotates and drives the moving rod (74) to move away from the axis of the drive gear (75) on the fixed shaft (73) to lower the metal mesh clamp. Step 4: Start the deceleration self-locking motor (81), rotate the bracket (82) to drive the upper mold (85) to move towards the lower mold (4), start the second electric telescopic rod (83), the second electric telescopic rod (83) extends and drives the fixed lock (84) to rotate, so that the opening of the fixed lock (84) is tightly attached to the locking shaft (10), thereby locking the upper and lower molds (4), start the second cylinder (11), the second cylinder (11) starts and drives the lifting platform (12) to move upward, so that the lower mold (4) squeezes the upper mold (85). Start the second cylinder (11). The second cylinder (11) starts and drives the lifting platform (12) to move downward. At this time, repeat step one and start the second electric telescopic rod (83). The second electric telescopic rod (83) shortens and drives the fixed lock (84) to rotate, so that the opening of the fixed lock (84) is away from the locking shaft (10). Start the deceleration self-locking motor (81). The rotating bracket (82) rotates and drives the upper mold (85) to move away from the lower mold (4). Take out the product after molding and proceed to the next product molding.
