Description

Technical Field

[0001] The utility model belongs to the technical field of liner molds, and specifically relates to a positioning mold for a steel-rubber composite liner. Background Art

[0002] A steel-rubber composite liner mold is a mold used for producing steel-rubber composite liners, also known as a steel-rubber composite plate mold. The steel-rubber composite body is a new type of material with characteristics such as high strength, high wear resistance, and corrosion resistance, and is widely used in the conveying systems of industries such as mining, metallurgy, electric power, and cement to protect the inner walls of conveying equipment and extend the service life of the equipment.

[0003] Currently, the positioning method used in existing steel-rubber composite liner molds is to respectively open threaded holes on both sides of the center position of the steel-rubber composite liner mold, threadedly connect positioning bolts in the threaded holes, and then install the positioning bolts on the upper template to complete the positioning and fixing of the steel-rubber composite liner mold.

[0004] Although the steel-rubber composite liner mold can be positioned and fixed by the positioning bolts on both sides of the center position of the steel-rubber composite liner mold, under the fixation of the two positioning bolts on both sides, due to the inability to ensure that the fixing forces of the two positioning bolts are the same, stress distribution unevenness will occur in the area where the steel-rubber composite liner mold surrounds the positioning bolts, resulting in a decrease in the stability of the steel-rubber composite liner mold and causing product scrapping. Content of the Utility Model

[0005] To solve the technical problem of the decreased stability of the composite liner mold, the utility model provides a positioning mold for a steel-rubber composite liner.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A positioning mold for a steel-rubber composite liner includes an upper template. A liner body is arranged below the upper template. A positioning bolt is connected to the middle of the liner body. An installation groove is opened at the position of the upper template corresponding to the positioning bolt, and the positioning bolt is installed in the installation groove.

[0008] Preferably, the upper part of the positioning bolt is frustum-shaped, and the shape of the installation groove corresponds to that of the positioning bolt.

[0009] Preferably, symmetrically arranged telescopic grooves are opened in the middle of the upper part of the positioning bolt. A positioning block is slidably connected in the telescopic grooves. A spring is connected between the positioning block and the positioning bolt. Symmetrically arranged positioning grooves are opened at the position of the positioning bolt corresponding to the positioning block, and the positioning block is inserted into the positioning grooves.

[0010] Preferably, a first arc surface is opened above the end of the positioning block away from the spring, and a second arc surface is opened below the upper template corresponding to the installation groove. The first arc surface and the second arc surface are used in cooperation.

[0011] Preferably, a connecting rod is obliquely connected below the positioning block, the lower end of the connecting rod is close to the center of the positioning bolt, a pressing rod is obliquely arranged below the connecting plate, the lower end of the pressing rod is close to the center of the positioning bolt, the lower end of the pressing rod is connected with a sliding rod, the sliding rod is slidably connected in the positioning bolt, and the lower ends of the two sliding rods are respectively connected with a pressing plate outside the positioning bolt.

[0012] Preferably, an activity groove is formed in the positioning bolt corresponding to the position of the connecting rod, and the connecting rod is slidably connected in the activity groove.

[0013] Preferably, the width of the activity groove is smaller than the width of the telescopic groove.

[0014] Preferably, positioning plates are connected to the middle parts of the two sliding rods, the positioning plates are located in the positioning bolt, and the lower surface of the positioning plate is attached to the bottom of the positioning bolt.

[0015] The beneficial effects of the utility model are as follows:

[0016] By arranging the positioning bolt in the middle of the lining plate body, the fixing force can be transmitted centrally, thereby improving the stability of the lining plate body, avoiding production accidents during the use of the lining plate body, further reducing the risk of product scrapping and improving the product quality. Arranging the positioning bolt in the middle of the lining plate body can also make the force distribution of the lining plate body more uniform, reduce the wear of the lining plate body during use, extend the service life of the lining plate body, and make the installation and replacement of the lining plate body more convenient, reducing the workload of operators.

[0017] By arranging the first arc surface and the second arc surface, the stress between the positioning block and the upper template can be dispersed, avoiding deformation and damage of the positioning block due to excessive stress; at the same time, after the contact area between the positioning block and the upper template is reduced, the wear of the contact surface can be reduced, thereby extending the service life of the positioning block and the upper template.

[0018] By aligning the upper end of the positioning bolt connecting the lining plate body with the position of the installation groove below the upper template, inserting it upward after alignment, and stopping inserting the positioning bolt after the outer side of the positioning bolt fits with the inner wall of the installation groove, at this time, there is a large frictional force between the positioning bolt and the upper template, so that the positioning bolt and the lining plate body are initially fixed. When the insertion of the positioning bolt stops, the positioning block and the positioning groove correspond to each other. Under the action of the spring restoring force, the spring resets and drives the positioning block to slide out of the telescopic groove and insert into the positioning groove, further fixing the positioning bolt and the lining plate body and making the positioning bolt and the lining plate body more stable.

[0019] By pressing the pressing plate upward, the sliding rod slides within the positioning bolt and moves upward. The upward movement of the sliding rod drives the extrusion rod to move upward. During the upward movement of the extrusion rod, it will extrude the connecting rod and cause the connecting rod to move towards the center position of the positioning bolt. During the movement of the connecting rod, it drives the positioning block to slide into the telescopic groove. After the positioning block completely enters the telescopic groove, the positioning bolt loses the fixation of the positioning block, and pulling the positioning bolt downward can remove the positioning bolt and the lining plate body, and replace other lining plate bodies, making it more convenient to remove the positioning bolt and the lining plate body during disassembly, thereby improving work efficiency.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figure 1 - Figure 4 As shown, a positioning mold for a steel-rubber composite liner includes an upper template 1. A liner body 2 is arranged below the upper template 1 to protect the upper template 1 and extend its service life.

[0033] A positioning bolt 3 is connected to the middle of the liner body 2 to connect the upper template 1 and the liner body 2.

[0034] It should be noted here that: compared with the original setting of the positioning bolt 3 on both sides of the center position of the liner body 2, the position of the positioning bolt 3 is now changed and the positioning bolt 3 is set in the middle of the liner body 2, which has the following advantages: 1. It can centrally transmit the fixing force, thereby improving the stability of the liner body 2, avoiding production accidents during the use of the liner body 2, and further reducing the risk of product scrapping and improving the product quality;

[0035] 2. It can make the force distribution of the liner body 2 more uniform, reduce the wear of the liner body 2 during use, and extend the service life of the liner body 2;

[0036] 3. It can make the installation and replacement of the liner body 2 more convenient and reduce the workload of the operator.

[0037] An installation groove 101 is opened at the position of the upper template 1 corresponding to the positioning bolt 3. The positioning bolt 3 is installed in the installation groove 101. The installation groove 101 cooperates with the positioning bolt 3 to install and position the positioning bolt 3 and the liner body 2.

[0038] The upper part of the positioning bolt 3 is frustum-shaped. The shape of the installation groove 101 corresponds to that of the positioning bolt 3. By setting the positioning bolt 3 to be frustum-shaped, when installing the positioning bolt 3 and the liner body 2, the positioning bolt 3 can be inserted into the installation groove 101 more quickly and accurately, thereby improving the efficiency;

[0039] A symmetrically arranged telescopic groove 31 is opened in the middle of the upper part of the positioning bolt 3 for accommodating a spring 32 and a positioning block 33;

[0040] A positioning block 33 is slidably connected in the telescopic groove 31. A spring 32 is connected between the positioning block 33 and the positioning bolt 3. The positioning block 33 is used to fix the positioning bolt 3 and the liner body 2, and the spring 32 is used to reset the positioning block 33;

[0041] The positioning bolt 3 is provided with symmetrically arranged positioning grooves 331 corresponding to the positions of the positioning blocks 33. The positioning blocks 33 are inserted into the positioning grooves 331. The cooperation between the positioning blocks 33 and the positioning grooves 331 can make the positioning bolt and the lining plate body 2 more stably fixed on the upper template 1;

[0042] Above one end of the positioning block 33 far from the spring 32, a first arc surface 332 is provided. Below the upper template 1 corresponding to the installation groove 101, a second arc surface 333 is provided. The first arc surface 332 and the second arc surface 333 are used in cooperation. When installing the positioning bolt 3 and the lining plate body 2, the contact area between the positioning block 33 and the upper template 1 can be reduced, thereby reducing the friction and resistance generated due to the too large contact area, and enabling the positioning block 33 to smoothly slide into the inside of the telescopic groove 31;

[0043] It should be noted here that: by setting the first arc surface 332 and the second arc surface 333, the stress between the positioning block 33 and the upper template 1 can be dispersed, avoiding deformation and damage of the positioning block 33 due to excessive stress; at the same time, after the contact area between the positioning block 33 and the upper template 1 is reduced, the wear of the contact surface can be reduced, thereby extending the service life of the positioning block 33 and the upper template 1.

[0044] During specific use, the upper end of the positioning bolt 3 connecting the lining plate body 2 is aligned with the position of the installation groove 101 below the upper template 1. After alignment, it is inserted upward. During the insertion process, the upper end of the positioning bolt 3 will first enter the inside of the installation groove 101, and then the first arc surface 332 at the upper end of the positioning block 33 will contact the second arc surface 333 below the upper template 1. After contact, the upper template 1 will squeeze the positioning block 33, causing the positioning block 33 to slide into the telescopic groove 31. During the sliding process of the positioning block 33, the spring 32 will be squeezed, and the spring 32 will contract and store the restoring force when being squeezed. After the positioning block 33 slides into the telescopic groove 31, the positioning bolt 3 is inserted upward continuously. After the outer side of the positioning bolt 3 fits with the inner wall of the installation groove 101, the insertion of the positioning bolt 3 is stopped. At this time, there is a large frictional force between the positioning bolt 3 and the upper template 1, making the positioning bolt 3 and the lining plate body 2 initially fixed. When the insertion of the positioning bolt 3 is stopped, the positioning block 33 and the positioning groove 331 correspond to each other. Under the action of the restoring force of the spring 32, the spring 32 resets and drives the positioning block 33 to slide out of the telescopic groove 31 and insert into the positioning groove 331, further fixing the positioning bolt 3 and the lining plate body 2 and making the positioning bolt 3 and the lining plate body 2 more stable.

[0045] The positioning block 33 is obliquely connected with a connecting rod 34 at the lower part. The lower end of the connecting rod 34 is close to the center of the positioning bolt 3. The connecting rod 34 is used to assist in driving the positioning block 33 to slide into the telescopic groove 31;

[0046] The positioning bolt 3 is provided with an activity groove 341 corresponding to the connecting rod 34. The connecting rod 34 is slidably connected in the activity groove 341. Through the cooperation of the activity groove 341, the connecting rod 34 can move smoothly;

[0047] The width of the activity groove 341 is smaller than the width of the telescopic groove 31. By this setting method, after the positioning block 33 slides into the telescopic groove 31, the positioning block 33 can be prevented from falling off from the telescopic groove 31;

[0048] A pressing rod 35 is inclinedly arranged below the connecting plate. The lower end of the pressing rod 35 is close to the center of the positioning bolt 3. The upper end of the pressing rod 35 is higher than the lower end of the connecting rod 34. The connecting rod 34 is in contact with the pressing rod 35. The pressing rod 35 is used to press the connecting rod 34, so that the connecting rod 34 drives the positioning block 33 to slide into the telescopic groove 31;

[0049] The lower end of the pressing rod 35 is connected with a sliding rod 36. The sliding rod 36 is slidably connected in the positioning bolt 3. The sliding rod 36 is used to assist the pressing rod 35 to press the connecting rod 34;

[0050] The lower ends of the two sliding rods 36 are respectively connected with a pressing plate 37 outside the positioning bolt 3. The pressing plate 37 is used to connect the two sliding rods 36, so that the two sliding rods 36 can slide simultaneously, and then move the two pressing rods 35 at the same time;

[0051] The middle parts of the two sliding rods 36 are both connected with a positioning plate 4. The positioning plate 4 is located in the positioning bolt 3. The lower surface of the positioning plate 4 is in contact with the bottom of the positioning bolt 3. The positioning plate 4 is used to position the two sliding rods 36 to prevent the sliding rods 36 from shifting or falling off from the positioning bolt 3;

[0052] During specific use, by pressing the pressing plate 37 upward, the sliding rod 36 slides and moves upward in the positioning bolt 3. The upward movement of the sliding rod 36 drives the pressing rod 35 to move upward. During the upward movement of the pressing rod 35, the connecting rod 34 will be pressed, and the connecting rod 34 will move toward the center position of the positioning bolt 3. During the movement of the connecting rod 34, the positioning block 33 is driven to slide into the telescopic groove 31. After the positioning block 33 completely enters the telescopic groove 31, the positioning bolt 3 loses the fixation of the positioning block 33. Pulling the positioning bolt 3 downward can disassemble the positioning bolt 3 and the lining body 2, and replace other lining bodies 2, which will be more convenient when disassembling the positioning bolt 3 and the lining body 2, and thus improve the work efficiency.
