Description

TECHNICAL FIELD

[0001] The utility model relates to an aluminum casting modeling filter screen leak release mistake prevention device. BACKGROUND

[0002] The casting filter screen is an auxiliary material used in the casting process, mainly used for filtering impurities and waste in the metal solution to ensure the quality and precision of the casting. However, in actual operation, the casting filter screen needs to be placed at the pouring opening before re-pouring to achieve the effect of filtering impurities and waste. But due to the need for manual operation hundreds of times a day, the problem of missing placement often occurs during operation, and after missing placement, the mold can still be closed and poured. Finally, it will cause defects in the casting, affect the forming effect and increase the scrap rate, which needs to be improved. SUMMARY

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide an aluminum casting modeling filter screen leak release mistake prevention device, which is not only reasonable in structure, but also has high yield.

[0004] In order to solve the above technical problems, the technical scheme of the utility model is as follows: an aluminum casting modeling filter screen leak release mistake prevention device, comprising a support table, a filter screen box for stacking filter screens is fixedly arranged on the top of the support table, a placing table divided into three compartments by a partition plate is fixedly arranged beside the filter screen box, a pressing rod for connecting the filter screen to the pouring opening is placed in one of the compartments, and filter screens are placed in the other two compartments; a through hole is formed in the bottom of each compartment, and an inductor is arranged below the through hole.

[0005] Further, the pressing rod comprises a bottom plate and a counterweight fixedly connected to the bottom of the bottom plate, and a vertical pressing rod is fixedly connected to the upper end of the bottom plate.

[0006] Further, a plurality of limiting blocks are uniformly distributed along the outer periphery of the bottom plate.

[0007] Further, the counterweight is in the shape of a cylinder, and the counterweight and the bottom plate are coaxially arranged and fixedly connected by bolts.

[0008] Further, the filter screen is circular, and a ring net is vertically protruded from the edge of the filter screen, that is, the edge is bent towards one side, so that the ring net and the filter screen form a disc shape to better fit on the counterweight.

[0009] Further, a single filter screen is horizontally placed in the compartment on the side close to the pouring opening and the middle compartment, and the pressing rod is vertically placed in the compartment on the side away from the pouring opening.

[0010] Further, the support table is fixedly connected to the side of the pouring table, a lower mold is arranged on the pouring table, and the pouring opening is formed in the lower mold.

[0011] Compared with the prior art, the present invention has the following advantages: by combining the placement platform with the sensor, it can be ensured that there is a filter screen to guarantee the quality of each casting, and there will be no problem of missing the filter screen. Because if the filter screen is missed, the mold cannot be closed and the casting cannot be completed, thus effectively avoiding losses caused by errors or missing filter screens.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0018] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0019] like Figures 1-4 As shown, the aluminum casting molding filter screen leakage prevention device includes a support platform 1. A filter screen box 3 for stacking filter screens 2 is fixed on the top of the support platform. A placement platform 5 divided into three compartments by a partition 4 is fixed on the side of the filter screen box. One compartment contains a screen pressing rod 7 to facilitate the connection of the filter screen to the casting port 6, which is located at the lower mold. The other two compartments each contain filter screens. Each compartment has a through hole 8 at the bottom, and a sensor 9 is installed below each through hole. The top of the filter screen box and the placement platform are open to facilitate the removal and placement of the filter screen.

[0020] In this embodiment of the utility model, the pressure bar includes a base plate 10 and a counterweight block 11 fixed to the bottom of the base plate, and a vertically extending pressure bar 12 is fixed to the upper end of the base plate.

[0021] In this embodiment of the utility model, the base plate is provided with a plurality of limiting blocks 13 evenly distributed along its outer periphery.

[0022] In this embodiment of the utility model, the counterweight is cylindrical, and the counterweight is coaxially arranged with the base plate and fixedly connected by bolts 14.

[0023] In this embodiment of the utility model, the filter screen is circular, and a ring mesh 15 protrudes vertically along its edge, that is, the edge is bent to one side. The ring mesh and the filter screen are fixed together, and the ring mesh and the filter screen form a disc shape to better fit onto the counterweight.

[0024] In this embodiment of the invention, a single filter screen is horizontally placed in the compartment near the casting port and in the middle, and the screen pressing rod is vertically placed in the compartment away from the casting port.

[0025] In this embodiment of the utility model, the support platform is fixedly connected to the side of the casting platform 16, the casting platform is provided with a lower mold 17, the casting port is opened in the lower mold, and an upper mold for the lower cover during casting is provided above the lower mold.

[0026] The working principle of this utility model embodiment is as follows: First, pick up the pressure rod and insert it into the foremost compartment so that the filter screen in that compartment is fitted onto the counterweight (only a small amount of friction is needed to prevent the filter screen from falling off). Then, with the filter screen in place, vertically insert it into the casting gate. The friction at the casting gate is greater than that on the counterweight surface, meaning the filter screen will remain at the casting gate. Then, pull out the pressure rod. The downward distance of the pressure rod is limited by a limiting block; that is, the lower end of the limiting block abuts against the outer edge of the casting gate, preventing the filter screen from descending excessively and causing incorrect positioning or direct detachment from the lower mold, ensuring accurate placement of the filter screen. The filter screens in the middle compartments are then placed sequentially. The casting is moved into the lower mold (which has two sets of mold cavities, allowing for the molding of two sets of castings at once). Finally, the pressure rod is reset and placed in the compartment. When the sensor does not detect the two filter screens but detects the pressure rod, the upper mold can move down to cover the lower mold and complete the casting. At this point, the two filter screens need to be taken out of the filter screen box and placed into the two compartments in turn. The sensor will detect the two filter screens in place and the casting is completed. Only then will the upper mold open and the cast casting can be removed. The above operation can be repeated. This operation method can ensure that there are filter screens in each casting to guarantee quality and avoid losses caused by mistakes or missing filter screens.

[0027] This utility model is not limited to the preferred embodiment described above. Anyone can derive other various forms of aluminum casting-shaped filter screen leakage prevention devices based on the inspiration of this utility model.
