Description

Technical Field

[0001] This utility model relates to a casting spraying device, and more particularly to a positioning and protection device for casting sand core processing. Background Technology

[0002] Resin sand spraying is a crucial step in the processing of casting sand cores. However, traditional resin sand spraying methods have the following drawbacks: ① In traditional spraying methods, the resin sand is usually suspended and in a swaying state. This unstable spraying environment makes it difficult for workers to perform precise spraying, resulting in inconsistent spraying quality and seriously affecting the processing accuracy and quality of the casting sand cores. ② During resin sand spraying, the coating is prone to splashing; this not only wastes coating and increases production costs, but also interferes with workers, hindering the smooth progress of construction and seriously affecting worker safety and work efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a positioning and protection device for casting sand core processing, which effectively solves the problems of low spraying accuracy, paint splashing polluting the environment, and insufficient operation safety and convenience in the traditional resin sand spraying process, thereby improving the processing quality and production efficiency of casting sand cores.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A positioning and protection device for processing casting sand cores includes a hopper, a support frame at the top of the hopper, first legs at the four corners of the bottom of the support frame, a rear baffle vertically arranged at the rear of the support frame, a displacement frame slidably connected above the support frame, a support mesh at the top of the inner cavity of the displacement frame, a limit block on the displacement frame outside the support mesh, an insert through the middle of the side of the displacement frame, a U-shaped baffle vertically arranged at the rear end of the insert, and a surrounding plate on the outside of the support frame.

[0005] The enclosure is made of transparent material and is U-shaped. An operating opening is provided in the lower middle part of the front end face of the enclosure. A U-shaped support frame is provided at the bottom of the enclosure. A handle is provided on the outer wall of the U-shaped support frame. A second leg is provided at the bottom of the U-shaped support frame, and a roller is provided at the bottom of the second leg.

[0006] The bottom of the hopper is provided with a discharge port, and a valve is provided at the discharge port.

[0007] The insert is fixedly connected to the displacement frame by bolts, and the displacement frame is fixedly connected to the support frame by bolts.

[0008] The height of the enclosure panel is the same as the height of the rear baffle.

[0009] The positive and beneficial effects of this utility model are: 1. This utility model, by setting a transparent enclosure on the outside of the support frame, in conjunction with the use of a back baffle, not only ensures that operators can clearly observe the spraying process, but also effectively blocks paint splashing, preventing paint from polluting the surrounding environment and maintaining the cleanliness of the workshop; when in use, the staff inserts the nozzle into the operating port to spray the sand core or sand mold, which can minimize paint splashing from the operating port and further reduce environmental risks.

[0010] 2. This utility model provides a stable support platform for resin sand by sliding a displacement frame above the support frame; by setting a support net at the top of the inner cavity of the displacement frame, the resin sand can be effectively supported, keeping it stable during the spraying process, avoiding the problem of uneven spraying caused by shaking, and significantly improving the accuracy and quality of spraying.

[0011] 3. This utility model, by setting a limiting block on the displacement frame and inserting a bracket through the side of the displacement frame, combined with the use of a U-shaped baffle, can accurately position the resin sand, ensure the accuracy of the spraying position, and further improve the spraying effect.

Detailed Implementation

[0013] The present invention will be further explained and described below with reference to the accompanying drawings: See the example. Figures 1-3A positioning and protection device for processing casting sand cores includes a hopper 3, a support frame 1 at the top of the hopper 3, first legs 2 at the four corners of the bottom of the support frame 1, a rear baffle 4 vertically arranged behind the support frame 1, a displacement frame 5 slidably connected above the support frame 1, a support net 6 at the top of the inner cavity of the displacement frame 5, a limit block 9 on the displacement frame 5 outside the support net 6, a bracket 8 penetrating through the middle of the side of the displacement frame 5, a U-shaped baffle 8 vertically arranged at the rear end of the bracket 7, and a surrounding plate 13 on the outside of the support frame 1.

[0014] In the above description, the enclosure is located outside the support frame and the displacement plate.

[0015] The enclosure 13 is made of transparent material and is U-shaped. An operating port 14 is provided in the lower middle part of the front end face of the enclosure 13. A U-shaped support frame 10 is provided at the bottom of the enclosure 13. A handle is provided on the outer wall of the U-shaped support frame 10. A second support leg 11 is provided at the bottom of the U-shaped support frame 10, and a roller 12 is provided at the bottom of the second support leg 11.

[0016] A discharge port is provided at the bottom of hopper 3, and a valve is provided at the discharge port for the collection and secondary use of paint, which is not shown in the figure.

[0017] The insert 7 is fixedly connected to the displacement frame 5 by bolts, and the displacement frame 5 is fixedly connected to the support frame 1 by bolts.

[0019] In the above description, by setting handles on the outside of the U-shaped support frame, it is convenient for workers to move the enclosure.

[0020] Working principle: Before use, remove the surrounding panels and use a lifting device to hoist the sand core onto the support net. Adjust the extension and retraction of the insert frame according to the size of the sand core to support the back of the sand core. Then, move the displacement frame to the upper middle part of the hopper and move the surrounding panels outside the displacement frame. After completion, insert the paint spray gun into the operating port to spray the sand mold or sand core. After spraying, control the valve at the discharge port at the bottom of the hopper to discharge the remaining resin sand, which facilitates cleaning and recycling, improves resource utilization, and reduces equipment blockage caused by residual resin sand, ensuring the normal operation and service life of the device.

[0021] This device effectively solves the problems of inaccurate spraying caused by resin sand shaking, waste, environmental pollution, and health hazards caused by paint splashing during traditional resin sand spraying, through its stable support and precise positioning functions. It significantly improves spraying quality and work efficiency, while providing good protection for operators, ensuring their safety and health. It has significant practical value and broad application prospects.
