Description

Technical Field

[0001] The invention belongs to the field of rubber molding die automation equipment, and in particular relates to an automatic mold opening machine for a rubber molding die. Background Art

[0002] At present, most rubber products and rubber composite products are produced by compression vulcanization. Vulcanization is also called cross-linking and aging. It is a process of adding cross-linking agents such as vulcanizers and accelerators to rubber to transform linear macromolecules into three-dimensional network structures under certain temperature and pressure conditions. Since sulfur was first used to achieve cross-linking of natural rubber, it is called vulcanization; and a vulcanizer is a machine that vulcanizes various rubber and plastic products, usually a hydraulic mechanical flat vulcanizer; the operation process of a flat vulcanizer is roughly divided into several steps, such as preheating, opening the plate to release the mold, sending the plate to press the mold, and opening the plate to take the mold.

[0003] In the prior art, after the compression mold is loaded with rubber and compound, it needs to rely on manual labor to close the mold and push the whole mold into the vulcanizer; after the vulcanization is completed, it still needs manual labor to pull out the whole mold and open the mold; finally, it needs to rely on manual labor to send the empty mold after the product is taken out into the cooling machine. Since the overall weight of the compression molds used in vulcanizers of different specifications is different, the production of a rubber product requires a complete mold opening and closing and mold transfer process, and the operator needs to repeat this process several times within a day. Therefore, the current production method has great defects: first, it brings great labor intensity to the operators; second, there are certain safety hazards; third, it reduces production efficiency; fourth, it requires the joint efforts of multiple people to complete, which increases production costs; fifth, manual participation reduces the stability of mold closing, thereby affecting the quality stability of the product.

In the present embodiment, the chain conveyor line mechanism is a two-level conveyor chain group, which includes a front conveyor chain group 103 and a rear conveyor chain group 104. The front and rear conveyor chain groups are both arranged at the upper ends of the left and right upright frames. The front and rear conveyor chain groups each include two parallel conveyor chains. The conveyor chains are connected to a chain drive mechanism 105. The chain drive mechanism 105 can drive the conveyor chains to rotate, thereby generating the ability to transport toward the inner and outer sides of the jaw (X-axis direction in the figure); the chain drive mechanism 105 includes a double-headed double-output motor and a chain transmission device. The left and right output ends of the double-headed double-output motor are each connected to a group of chain transmission devices. The chain transmission device connects and drives the two conveyor chains on one side.

[0054] The displacement latch mechanism 206 includes a latch cylinder and a latch head. Four groups of latch cylinders are horizontally arranged at the four corners of the lower end of the flip frame. The output end of the latch cylinder is connected to the latch head. The latch head corresponds to the latch hole 801 on the lifting frame 8. The four groups of latch heads can be horizontally inserted into the latch holes 801 of the corresponding lifting frames 8 to complete the latch fixation of the upper mold 601. After the latch fixation action is completed, the flip mold opening system 2 completes the flipping of the upper mold 601 by lifting the flip frame through the flip cylinder 202.

The mold opening lifting cylinders can lift the upper mold 601 relative to the lower mold 602 and to the bottom of the flip supporting frame 203 to complete the mold opening of the upper and lower molds.

[0057] The lower mold fixing assembly includes a locking motor and a flip claw connected thereto. The locking motor is arranged on the workbench frame 301. The flip claws of the four groups of lower mold fixing assemblies can be flipped out from their corresponding lower mold fixing holes to lock the mold frame 7, thereby fixing the lower mold 602 when the mold opening lifting cylinder lifts the upper mold 601.

[0058] See also Figure 6 In order to further improve the automation level of the automatic mold opening machine of this embodiment, the device also includes a translation conveyor line system 4, which is arranged between the two conveyor chains of the second stage, and between the lifting conveyor line system 1 and the mold opening and filling workbench system 3.
