Description

Technical Field

[0001] This utility model relates to a casting sand removal device, and more particularly to a venting device for high-pressure pump valve casting, belonging to the field of casting cleaning technology. Background Technology

[0002] During the casting process of high-pressure pumps and valves, impurities such as sand, molding sand, and gating system residues often remain inside the castings. Therefore, it is necessary to clean the internal cavity of the castings later to ensure the quality and performance of the castings. Traditional cleaning methods mainly rely on manual operation, that is, using high-pressure water guns or air guns to clean the inner walls of the castings, especially the exhaust channels. This method has many problems in practical applications: ① During the cleaning process, due to the excessive pressure of the water gun, the castings are prone to tipping over, and the workers need to frequently adjust the state of the castings, thereby reducing work efficiency and hindering the sand removal operation; ② During the cleaning process, the sand that is removed is easily sprayed by the water gun or air gun, which is not only difficult to collect and clean, but also pollutes the surrounding environment. This splashed sand may damage the surrounding equipment, increasing the difficulty and cost of the cleaning work. 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 venting channel unblocking device for high-pressure pump valve casting. This device can effectively fix the casting and prevent it from tipping over during the cleaning process. At the same time, it can collect the sand blocks that are cleaned up in a unified manner to prevent them from splashing and causing pollution and damage to the equipment. This improves cleaning efficiency and quality and reduces the labor intensity of the workers.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A device for clearing exhaust channels in high-pressure pump valve casting includes a rectangular frame and legs. The legs are located at the four corners of the bottom of the rectangular frame. A protective cover is installed above the rectangular frame. Positioning brackets are installed on both sides of the inner wall of the protective cover, and two limiting crossbars are installed between the two positioning brackets. A limiting longitudinal bar is bolted between the two limiting crossbars. A load-bearing net is installed on the bottom surface of the rectangular frame. The front end of the load-bearing net is rotatably connected to the inner wall of the rectangular frame, and the rear end of the load-bearing net extends beyond the rear of the rectangular frame and is fixed by a U-shaped limiting bracket and tightening bolts.

[0005] The outer walls on both sides of the rear end of the rectangular frame are respectively provided with insertion holes. The upper end of the U-shaped limiting frame passes through the insertion holes and is fixed by bolts on the outer wall of the insertion holes. The bottom of the U-shaped limiting frame is connected with a tightening bolt by a thread, thereby fixing the rear end of the load-bearing net.

[0006] The positioning brackets are U-shaped and are located at the lower part of the inner wall of the protective cover.

[0007] The limiting crossbar has matching U-shaped slots at both ends corresponding to the positioning brackets. The U-shaped slots are inserted into the limiting crossbar and fixed by matching bolts.

[0008] The top of the limiting crossbar is provided with bolt mounting holes at intervals.

[0009] There are two limiting longitudinal bars, which are respectively bolted to the top of the limiting transverse bar.

[0010] Limit bolts are provided on the outer walls of the top of both sides of the U-shaped limiting frame.

[0011] A handle is provided at the bottom right end of the load-bearing net.

[0012] The positive and beneficial effects of this utility model are: 1. This utility model forms a stable clamping structure by setting a limiting crossbar between two positioning brackets and a limiting longitudinal bar between the two limiting crossbars, which can firmly fix the casting and prevent the casting from tipping over during the cleaning process, thereby improving cleaning efficiency and quality and reducing the labor intensity of workers. At the same time, the spacing between the limiting crossbars and the limiting longitudinal bar can be freely adjusted according to the size of the casting, which improves the versatility and practicality of the device.

[0013] 2. This utility model features a load-bearing net at the bottom of a rectangular frame, with the front end of the net rotatably connected to the inner wall of the front end of the rectangular frame. The rear end of the net is fixed by a U-shaped limiting frame and a tightening bolt. This effectively collects sand that falls during the cleaning process, preventing sand from being sprayed by water or air guns. Furthermore, after the casting is cleaned, simply adjusting the position of the U-shaped limiting frame and the tightening bolt allows the rear end of the net to descend, thus collecting all the cleaned impurities. It is convenient to use and easy to operate.

[0014] 3. By setting a protective cover above the rectangular frame, this utility model can effectively prevent impurities generated during the cleaning process from splashing everywhere, making it easier for workers to clean and collect the impurities. At the same time, it ensures the cleanliness of the construction site and avoids damage to surrounding equipment caused by the cleaned-up impurities. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further explained and described below with reference to the accompanying drawings: See the example. Figures 1-4 A device for clearing exhaust channels in high-pressure pump valve casting includes a rectangular frame 1 and support legs 2. Support legs 2 are provided at the four corners of the bottom of the rectangular frame 1. A protective cover 3 is provided on the top of the rectangular frame 1. Positioning brackets 8 are provided on both sides of the inner wall of the protective cover 3. A limiting crossbar 9 is provided between the two positioning brackets 8. There are two limiting crossbars 9. A limiting longitudinal bar 11 is bolted between the two limiting crossbars 9. A load-bearing net 4 is provided on the bottom surface of the rectangular frame 1. The front end of the load-bearing net 4 is rotatably connected to the inner wall of the rectangular frame 1. The rear end of the load-bearing net 4 extends out of the rear of the rectangular frame 1 and is fixed by a U-shaped limiting bracket 6 and a tightening bolt 601.

[0017] In the above description, the load-bearing net can cover the bottom surface of the rectangular frame, and the two sides of the front end of the load-bearing net are rotatably connected to the inner wall of the bottom of the rectangular frame. The rear end of the load-bearing net is fixed by a U-shaped limiting bracket and a tightening bolt, thereby enclosing the bottom of the rectangular frame.

[0018] Insertion holes 5 are provided on the outer walls of both sides of the rear end of the rectangular frame 1. Insertion holes 5 are passed through the upper end of the U-shaped limiting frame 6 and fixed by bolts on the outer wall of the insertion holes 5. The bottom of the U-shaped limiting frame 6 is connected by a tightening bolt 601 through a thread, thereby fixing the rear end of the load-bearing net 4.

[0019] In the above description, when cleaning impurities, first unscrew the top bolts. At this time, the rear end of the load-bearing net moves down, and the load-bearing net is in a shape that is higher in the front and lower in the back. Then adjust the position of the U-shaped limit frame to make the opening between the rear end of the load-bearing net and the rear end of the rectangular frame larger, so that the impurities that have been cleaned out move out along the load-bearing net and are cleaned uniformly.

[0020] In the above description, a limiting bolt is installed at the top of the outer wall of the U-shaped frame to prevent the U-shaped limiting frame from falling out of the insertion hole.

[0021] The positioning brackets 8 are distributed in a U-shape and are located at the lower part of the inner wall of the protective cover 3.

[0022] At the positions of the positioning brackets 8 at both ends of the limiting crossbar 9, there are matching U-shaped slots 10. The U-shaped slots 10 are inserted into the limiting crossbar 9 and fixed by matching bolts.

[0023] In the above description, there are two limiting crossbars, and the distance between the two limiting crossbars is determined according to the size of the casting; the limiting crossbars are fixedly connected to the positioning bracket by the size of the outer wall of the U-shaped slot.

[0024] Bolt mounting holes are provided at intervals on the top of the limit crossbar 9.

[0025] There are two limiting longitudinal bars 11, which are respectively set on the top of the limiting horizontal bar 9 by bolts.

[0026] In the above description, the spacing between the two limiting longitudinal bars is determined according to the size of the casting; the limiting longitudinal bars and the limiting transverse bars are distributed in a cross shape.

[0027] Limit bolts 7 are installed on the outer walls of the top of both sides of the U-shaped limit frame 6.

[0028] A handle 401 is provided at the bottom right end of the load-bearing net 4 to facilitate adjustment of the position of the load-bearing net.

[0029] Working principle: Before use, use the U-shaped limiting bracket and tightening bolts to ensure that the rear end of the load-bearing net is in close contact with the bottom of the rectangular frame, ensuring that the bottom of the rectangular frame is covered by the load-bearing net; then place the casting on the load-bearing net, and adjust the position of the limiting horizontal bar and the limiting vertical bar according to the size of the casting, and clamp and fix the casting A around its perimeter; after fixing, the casting can be cleaned with an air gun or water gun.

[0030] After cleaning, the casting is removed, and then the top bolts at the bottom of the U-shaped limit frame are loosened and placed in the position of the U-shaped limit frame, so that the rear end of the load-bearing net moves down slowly, and the impurities flow out along the load-bearing net. The staff then cleans up the impurities.

[0031] This utility model is equipped with limiting horizontal and vertical bars, which can clamp and fix the casting, preventing it from tipping over during the cleaning process and improving work efficiency. By setting up a load-bearing net and protective cover, the sand blocks that are cleaned can be collected and cleaned in a unified manner, reducing environmental pollution and equipment damage, reducing labor intensity, ensuring the cleanliness of the construction site, and is convenient to use and easy to operate.
