Technical Field

The invention relates to the technical field of machining equipment, in particular to a screen plate machining die convenient for demolding.

Background

The metal mesh plate is a thin and porous plate which is cast using a casting mold. However, because of the thin thickness and the porous characteristic of the metal mesh plate, when the existing casting mold uses the ejector rod to demold, the contact area between the ejector rod and the metal mesh plate is small, so that the metal mesh plate is easy to be stressed unevenly, and the metal mesh plate sags and deforms when being jacked. For expanded metal, once deformed, it is very difficult to manually restore the original flatness, and the difficulty in restoring the flatness affects the subsequent use.

The invention aims to provide a screen plate processing mold convenient for demolding, and aims to solve the problems that in the prior art, demolding of a metal screen plate is easy to cause uneven stress and deformation.

In order to solve the above problems, the present invention provides the following technical solutions: the utility model provides a otter board mold processing convenient to drawing of patterns, includes frame and bed die, the bed die is equipped with into the die cavity, the frame is connected with the cylinder, the cylinder is connected with the mounting panel, the mounting panel is connected with motor and last mould, the motor is connected with the spool, the outer wall symmetry of going up the mould rotates and is connected with the upset pole, two be connected with the electro-magnetic plate that is located directly over the die cavity between the upset pole, the size of electro-magnetic plate matches with the size in die cavity, around having the rope between electro-magnetic plate and the spool, one of them upset pole is connected with first carbon-rod utmost point, it is equipped with the second carbon-rod utmost point that first carbon-rod utmost point is relative to go up the mould, form closed electric loop between first carbon-rod utmost point, electro-magnetic plate and the second carbon.

The working principle and the beneficial effects of the invention are as follows: this application is when casting, and motor control spool rotated this moment, and the spool passes through the rope and makes the electro-magnet plate rotate, and the bottom of mould is gone up in the electro-magnet plate upset and keep away from, and cylinder control mounting panel descends, goes up the top that the mould descends and falls into the bed die, begins to cast.

After the casting is finished, the cylinder controls the upper die to rise, the screen plate after casting is fully cooled, after cooling is finished, the winding shaft is controlled to rotate through the motor, the rope falls off from the winding shaft, the electromagnet plate rotates to the position right below the upper die, the first carbon rod electrode is in contact with the second carbon rod electrode, an electric circuit is conducted, the electromagnet plate is electrified to generate suction, the cylinder drives the upper die to descend through the piston rod, the upper die drives the electromagnet plate to descend together, the electromagnet plate enters the forming cavity, the cooled screen plate is adsorbed, and when the electromagnet plate is controlled by the cylinder to ascend, the electromagnet plate pulls out the screen plate from the forming cavity. Because the size of the electromagnet plate is matched with the size of the forming cavity, the electromagnet plate can completely adsorb the screen plate, the stress is uniform, and a certain part of the screen plate cannot droop to generate deformation.

Furthermore, the bottom of the upper die is provided with a positioning column, and the top of the lower die is provided with a positioning hole matched with the positioning column for use. Through aim at the locating hole with the reference column, conveniently assemble mould and bed die.

Furthermore, a plurality of heat dissipation holes are formed below the lower die and the forming cavity. The heat dissipation holes can dissipate heat, so that the cooling of the screen plate in the forming cavity is accelerated, and the production efficiency is improved.

Further, the upper die is provided with an exhaust groove communicated with the forming cavity. After last mould and bed die lock, pour the molten iron into towards the shaping intracavity through last mould, the molten iron is discharged the inside air of shaping intracavity through the air discharge duct, can prevent that the sand eye from appearing in the otter board.

Further, the upper die is also connected with a vertical limiting plate. When the rope on the spool drops, the electromagnet plate rotates towards the bottom of the upper die, the limiting plate can limit the rotation of the electromagnet, and the impact force generated by the descending of the electromagnet plate can be buffered.

Furthermore, the mounting panel is connected with the fixed pulley in a rotating way, and the rope is wound on the fixed pulley. The purpose of setting up like this can prevent that the rope from droing excessively, influencing the electromagnetism iron plate and adsorbing the otter board.

Furthermore, a plurality of vent holes are uniformly distributed on the electromagnet plate. When the electromagnet plate enters the forming cavity, air in the forming cavity is discharged through the vent holes, so that the electromagnet plate and the screen plate are more tightly adsorbed, and the uneven stress of the electromagnet plate is avoided.

Further, the mounting plate is connected with an air gun. The air gun can be sprayed air towards the electromagnet plate, so that dust is prevented from adhering to the surface of the electromagnet plate, the electromagnet plate and the screen plate can be adsorbed more tightly, and uneven stress is prevented from occurring.
