Abstract
Description
Technical Field
[0001] The utility model relates to an iron mold sand-coated casting production line, in particular to a box closing device for the iron mold sand-coated casting production line. Background Art
[0002] The iron mold sand coating production line mainly includes an iron mold conveyor line and equipment that cooperates with each station of the iron mold conveyor line, such as a turning mechanism of the turning station, a sand dropping mechanism of the sand dropping station, a box closing mechanism of the box closing station, and a pouring equipment of the pouring station. At present, at the box closing station, the upper iron mold is generally lifted to a certain height by a lifting mechanism, and then the upper iron mold is lowered after the lower iron mold reaches the set position to complete the box closing; the lifting mechanism is mainly composed of a lifting cylinder and a lifting claw. The lifting claw is located below the iron mold conveyor line in the initial state. When it needs to be lifted, it will rise under the drive of the lifting cylinder until it contacts the upper iron mold and drives it to rise. However, the current lifting mechanism only sets the upper iron mold on the lifting claw. When it is subjected to external vibration, the upper iron mold is prone to displacement; and after the upper iron mold is placed on the lower iron mold, the box closing is completed, and the phenomenon of pressing error between the upper and lower iron molds is prone to occur, that is, the upper and lower iron molds are not aligned, resulting in deviations in the size of the subsequent cast products. Therefore, the existing technology has the problem of deviation in the closing of the upper and lower iron molds. Utility Model Content
[0003] The purpose of the utility model is to provide a box closing device for an iron mold sand-coated casting production line. The utility model has the characteristic of being able to ensure the accuracy of closing the upper and lower iron molds.

DETAILED DESCRIPTION
[0012] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0013] Embodiment. The assembly device of the iron mold sand casting production line is composed of Figure 1-3 As shown, it includes a bracket located above the box closing station of the iron mold conveying line, a lifting cylinder is provided on the top of the bracket, a base plate is provided below the lifting cylinder, a bidirectional clamping mechanism perpendicular to the iron mold conveying direction is provided in the middle below the base plate, support rods are provided on the front and rear sides of the bidirectional clamping mechanism, and a clamping plate is provided at the lower end of the support rod; a verification mechanism is also provided on the clamping plate.
[0014] The verification mechanism includes a left verification support plate located at the left end of the front side of the clamping plate and a right verification support plate located at the rear side of the right end of the clamping plate; the left verification support plate and the right verification support plate are both L-shaped structures, and rangefinders are provided on both surfaces of the left verification support plate and the right verification support plate.
[0015] The bidirectional clamping mechanism includes a central double-headed cylinder fixed to the lower surface of the base plate, with slide rails at the front and rear ends of the double-headed cylinder, a slider connected to the output end of the double-headed cylinder is provided below the slide rail, and a support rod is fixed to the slider.
[0016] An iron mold in-place sensor is provided on the box closing station to monitor the iron mold in-place status. When the iron mold reaches the designated position, the iron mold conveyor line stops working.
[0017] The conveying direction of the iron profile conveyor line is left and right.
[0018] The bottom plate is connected to the base plate via the support legs.
[0019] The distance meter is connected with a PLC controller.
[0020] The PLC controller is also connected to a buzzer alarm and a warning light.
[0021] The distance meter is used to measure the position between the distance meter and the iron mold. When the distances measured by the four left and right points are the same or within the set error range, it means that the left and right sides of the upper iron mold and the lower iron mold are pressed accurately; the distances measured by the four front and rear measuring points are the same or within the set error range, it means that the front and rear sides of the upper iron mold and the lower iron mold are pressed accurately.
[0022] Preferably, the clamping surface of the clamping plate is provided with a rubber layer, and the surface of the rubber layer is provided with friction lines, which can effectively increase the friction coefficient and improve the clamping effect.
[0023] An electromagnet suction cup can also be arranged on the clamping plate to improve the clamping effect.
[0024] The left and right check support plates do not contact the upper and lower iron molds, and maintain a certain appropriate distance. The length of the clamping plate is consistent with the size of the iron mold, or slightly longer.
[0025] The working process of the utility model is as follows: when the upper iron mold arrives at the closing station, the iron mold conveying line stops moving, the lifting cylinder controls the base plate and the components below it to descend, so that the clamping plates are lowered to the clamping position height on the front and rear sides of the upper iron mold, and the two-way clamping mechanism works to drive the two clamping plates to move inward until they contact the clamping surface of the upper iron mold, and then the lifting cylinder drives the base plate and the components fixed on its lower surface to rise to the set height; the iron mold conveying line continues to move, and stops moving after conveying the lower iron mold to the closing station, and the lifting cylinder works again to drive the upper iron mold It descends until the upper iron mold fits the lower iron mold, and the two-way clamping mechanism drives the clamping plate to move outward a certain distance to release the upper iron mold; at this time, the distance meter on the left and right check support plates measures the distance between them and the upper iron mold; then, the lifting cylinder continues to descend, so that the left and right check support plates reach the measurement position corresponding to the lower iron mold, and the distance meter on the left and right check support plates detects the distance between them and the lower iron mold. If the distance detected up, down, left, and right meets the requirements, the iron mold conveyor line continues to move and the next box closing operation is carried out. If it does not meet the requirements, the buzzer alarm and warning light will be controlled to issue a reminder.
