Description

Technical Field

[0001] This utility model relates to the field of sand mold manufacturing technology, and in particular to an inflatable sealing ring for the sand door of a casting molding machine. Background Technology

[0002] A sand mold is a type of mold used in casting production. It is mainly made of raw sand, binder and other auxiliary materials. Sand mold production requires the use of a casting molding machine for processing. The sand gate of the casting molding machine has a cavity, and a ball valve is installed inside the cavity. This air-filled sealing ring is used in conjunction with the ball valve core.

[0003] When the existing inflatable sealing ring is inflated, the gap between the inflatable sealing ring and the valve core is sealed, preventing sand from passing through. After deflation, a gap remains, and the sealing ring becomes smaller. After long-term use of the ball valve, the gap at the connection between the sealing ring and the valve core may increase, causing the deflated sealing ring to fall outward from the valve core. Therefore, an auxiliary inflatable sealing ring is needed to prevent it from falling out after deflation. Utility Model Content

[0004] The purpose of this utility model is to provide an inflatable sealing ring for the sand gate of a casting molding machine, in order to solve the problems mentioned in the background art. When the existing inflatable sealing ring is inflated, the gap between the inflatable sealing ring and the valve core is sealed, and sand cannot pass through. After deflating, a gap remains. After the sealing ring is deflated, its size becomes smaller. After long-term use of the ball valve, the gap at the connection between the sealing ring and the valve core may become larger, which may cause the deflated sealing ring to fall outward from the valve core.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an inflatable sealing ring for the sand gate of a casting molding machine, comprising:

[0007] An inflatable sealing assembly, the inflatable sealing assembly including a mounting end;

[0008] The connecting assembly includes a connecting plate, a spring, a fixing plate, a magnetic surface, and a friction surface. The connecting plates are arranged in a set and are all snapped onto the outer surface of the mounting end. The springs are arranged in a set and are fixed to the outer end of the connecting plates. The fixing plate is located at the outer end of the springs. The magnetic surface and the friction surface are both fixedly connected to the outer end surface of the fixing plate and are placed alternately.

[0009] Furthermore, the connecting plate has a connecting groove at the snap-fit ​​point with the mounting end, and the mounting plate is fixedly connected to the outer end of the spring.

[0010] Furthermore, the outer end of the spring is fixedly connected to one side of the fixing plate, and the mounting plate, fixing plate and connecting groove are engaged.

[0011] Furthermore, it also includes auxiliary connection components;

[0012] The auxiliary connection assembly includes a magnetic surface, a mounting groove, and a fixing rod; the magnetic surface is fixed to one end of the inner side of the connection groove, the mounting groove is opened at the corner of the magnetic surface, and the fixing rod is fixed at the corner of the back side of the connection plate.

[0013] Furthermore, each of the fixing rods is fixedly connected to a connecting pad at one end, and the connecting pad engages with the mounting groove.

[0014] Furthermore, the inflatable sealing assembly also includes a sealing end; the sealing end is fixed to the top of the mounting end.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model, by setting a connecting component, when the sealing ring is connected to the valve core, the fixing plate abuts against the valve core through the spring, and at the same time the magnetic surface attracts the valve core. The friction surface increases the friction between the fixing plate and the valve core, thereby promoting a stable connection between the sealing ring and the valve core. When the sealing ring is deflated, the sealing ring is still stably connected to the valve core through the magnetic surface and the friction surface, preventing the sealing ring from falling out of the valve core after deflating.

[0017] Second, based on the first beneficial effect, by setting up an auxiliary connection component, when the connection plate is installed, the fixing rod, the connecting pad and the mounting groove are aligned, and the connection plate is pushed so that the fixing rod is engaged with the mounting groove through the connecting pad, and the back of the connection plate is attracted to the magnetic surface, thereby stabilizing the connection between the connection plate and the connection groove, and at the same time facilitating the individual replacement of each fixing plate and mounting plate.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figures 1-3 As shown, this embodiment is an inflatable sealing ring for the sand gate of a casting molding machine, comprising:

[0029] An inflatable sealing assembly, which includes a mounting end 11;

[0030] The inflatable sealing assembly also includes a sealing end 12; the sealing end 12 is fixed to the top of the mounting end 11;

[0031] The mounting end 11 and the sealing end 12 together form a sealing ring.

[0032] The connecting assembly includes a connecting plate 22, a spring 23, a fixing plate 25, a magnetic surface 26, and a friction surface 27. The connecting plates 22 are arranged in a group and are all snapped onto the outer surface of the mounting end 11. The springs 23 are arranged in a group and are fixed to the outer end of the connecting plate 22. The fixing plate 25 is located at the outer end of the springs 23. The magnetic surface 26 and the friction surface 27 are both fixedly connected to the outer end surface of the fixing plate 25, and the two are placed alternately.

[0033] The connecting plate 22 is used to connect the spring 23. There are six connecting plates 22 in total. The spring 23 is used to connect the mounting plate 24. There are two springs 23 in each group. The fixing plate 25 is used to set the magnetic surface 26 and the friction surface 27. The magnetic surface 26 is used to attract the fixing plate 25 to the valve core surface. The friction surface 27 is used to increase the friction between the fixing plate 25 and the valve core.

[0034] The connecting plate 22 has a connecting groove 21 at the snap-fit ​​point with the mounting end 11, and the outer end of the spring 23 is fixedly connected to the mounting plate 24;

[0035] The outer end of the spring 23 is fixedly connected to one side of the fixing plate 25, and the mounting plate 24, the fixing plate 25 and the connecting groove 21 are engaged.

[0036] The connecting groove 21 is used to connect the connecting plate 22, and the mounting plate 24 is used to connect the fixing plate 25. The fixing plate 25 is connected to the spring 23 through the mounting plate 24. When the spring 23 is compressed, the mounting plate 24 and the fixing plate 25 enter the connecting groove 21 through the spring 23, so that the mounting end 11 is firmly engaged with the valve core.

[0037] Working principle: When the component is not in use, the mounting end 11 is not connected to the valve core. When the component is in use, hold the sealing ring by hand, align the mounting end 11 with the valve core connection, and push the sealing ring so that the mounting plate 24 and the fixing plate 25 come into contact with the valve core, causing the spring 23 to contract. The mounting plate 24 and the fixing plate 25 enter the connecting groove 21 through the spring 23, so that the mounting end 11 is firmly locked to the valve core. At this time, the magnetic surface 26 attracts the valve core, and the friction surface 27 increases the friction between the fixing plate 25 and the valve core, thereby promoting the sealing ring to be firmly connected to the valve core. When the sealing ring is deflated, the sealing ring is still firmly connected to the valve core through the magnetic surface 26 and the friction surface 27.

[0038] The above steps can prevent the sealing ring from falling out of the valve core after it is released.

[0039] Please see Figures 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] Auxiliary connection components;

[0041] The auxiliary connection assembly includes a magnetic surface 31, a mounting groove 32, and a fixing rod 33; the magnetic surface 31 is fixed to one end of the inner side of the connection groove 21, the mounting groove 32 is opened at the corner of the magnetic surface 31, and the fixing rod 33 is fixed at the corner of the back side of the connection plate 22.

[0042] Each of the fixed rods 33 has a connecting pad 34 fixedly connected to one end, and the connecting pad 34 is engaged with the mounting groove 32;

[0043] The magnetic surface 31 is used for the adsorption connection between the connecting plate 22 and the inner side of the connecting groove 21. The mounting groove 32 is used for the insertion of the fixing rod 33. The fixing rod 33 is used for the connection of the connecting pad 34. The connecting pad 34 is elastic. When the fixing rod 33 is inserted into the mounting groove 32, the connecting pad 34 is squeezed against the outer end of the mounting groove 32, causing the connecting pad 34 to contract and enter the mounting groove 32. Since the inside of the mounting groove 32 is larger than the outer end, the connecting pad 34 unfolds in the mounting groove 32, so that the fixing rod 33 is firmly connected to the mounting groove 32 through the connecting pad 34.

[0044] Working principle: When the component is not in use, the fixing rod 33 is separated from the mounting groove 32. When the component is in use, hold the connecting plate 22, align the fixing rod 33 with the mounting groove 32, and push the connecting plate 22 so that the fixing rod 33 is inserted into the mounting groove 32. At this time, the connecting pad 34 is pressed against the outer end of the mounting groove 32, causing the connecting pad 34 to contract and enter the mounting groove 32. Since the inside of the mounting groove 32 is larger than the outer end, the connecting pad 34 unfolds in the mounting groove 32, so that the fixing rod 33 is firmly connected to the mounting groove 32 through the connecting pad 34, causing the connecting plate 22 to be attracted to the magnetic surface 31, thereby stabilizing the connection between the connecting plate 22 and the inside of the connecting groove 21, and making it easy to replace each fixing plate 25 and mounting plate 24 individually.

[0045] The above steps can improve its functionality.
