Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a steel bar protective layer pad mold. Background Art

[0002] In construction projects, rebar cover pads are critical structural elements used to ensure the correct placement and thickness of rebar cover within concrete components, thereby improving the safety and durability of the structure. Currently, molds for rebar cover pads widely used in the market are mostly manufactured using traditional injection molding or prefabricated molds. While these methods meet production needs to a certain extent, they still have some shortcomings. For example, the molding process often requires multiple opening and closing operations, which leads to wear and tear, and difficulty in demolding after wear, resulting in low production efficiency.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel bar protective layer pad mold, comprising a base plate, a mold sleeve and a piston, the mold sleeve is equidistantly installed on the bottom of the base plate, a conical groove is opened at the lower part of the interior of the mold sleeve, a piston is movably arranged inside the piston, a conical groove ring is provided at the bottom of the piston, and reinforcing ribs are provided on the top of the piston.

[0005] Preferably, the piston is made of tungsten steel and has a thickness of one millimeter.

[0006] Preferably, a limiting frame is provided inside the tapered notch.

[0007] Preferably, a plug is installed at the bottom of the piston, and the plug passes through the limiting frame.

[0008] Preferably, a mounting plate is installed on the outside of the base plate, and a mounting hole is opened inside the mounting plate.

[0009] In summary, this application has the following beneficial technical effects:

[0010] 1. This device is a forming mold for steel bar protective layer pads. After the forming operation is completed, push the plug to make the piston push out the steel bar protective layer pad and complete the demoulding. Because the top of the piston is designed with reinforcing ribs, it can ensure that the piston maintains its structural strength while being thinner. The piston thickness is designed to be within one millimeter, the friction is smaller, and the wear rate is lower after long-term use.

[0011] 2. The tapered notch adopts a certain inclined groove design, which can better fit when in contact with the piston, improve stability, reduce rounded corner wear, and improve durability. At the same time, a tapered notch is designed in the mold sleeve to achieve side wall inclination and an inverted cone shape. With this design, the piston only needs to move slightly by one millimeter to escape from the inside of the sleeve molding cavity, which is convenient for demolding.

[0018] The following is combined with Figure 1-5 , further details of this application are given.

[0019] A steel bar protective layer pad mold includes a base plate 1, a mold sleeve 2 and a piston 3. The mold sleeve 2 is equidistantly installed at the bottom of the base plate 1. The mold sleeve 2 serves as a forming mold cavity for the steel bar protective layer pad. The base plate 1 is designed to be installed and spliced ​​by screws and can be spliced ​​in multiple groups. Multiple groups can be selected for splicing, such as two groups, four groups, etc., so that users can perform large-scale processing and use according to actual usage needs. A tapered notch 201 is provided at the bottom of the mold sleeve 2. The tapered notch 201 adopts a certain inclined groove design, which can better fit when in contact with the piston 3, improve stability, reduce fillet wear, and improve durability. The piston 3 is movably provided with a piston 3. The mold sleeve 2 can form a chamber, and the formed steel bar protective layer pad can be demolded by the reciprocating motion of the piston 3. A tapered groove ring 301 is provided at the bottom of the piston 3. The design of the tapered groove ring 301 can help the piston 3 fit with the tapered notch 201. A reinforcing rib 303 is provided on the top of the piston 3. The design of the reinforcing rib 303 can improve the structural strength of the piston 3 and ensure the service life of the piston 3.

[0020] Reference Figure 1The piston 3 is made of tungsten steel and has a thickness of one millimeter. Tungsten steel has good wear resistance, and the thickness is designed to be within one millimeter, which has less friction and lower wear rate after long-term use.

[0021] Reference Figure 3 A limiting frame 202 is provided inside the tapered notch 201. The limiting frame 202 can limit the moving position of the piston 3 so as to facilitate product molding and also facilitate the demoulding operation.

[0022] Reference Figure 3 A plug 302 is installed at the bottom of the piston 3, and the plug 302 passes through the limit frame 202. The plug 302 can fit into the hole inside the limit frame 202, and the plug 302 can movably pass through the limit frame 202 to achieve reciprocating motion.

[0023] Reference Figure 2 A mounting plate 101 is installed on the outside of the substrate 1, and a mounting hole 102 is opened inside the mounting plate 101. By cooperating with the mounting plate 101 and the mounting hole 102, the substrate 1 can be fixedly installed in a specified position so that the device can be installed on an external tooling for use.

[0024] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0025] The implementation principle of a steel bar protective layer pad mold in the embodiment of the present application is as follows: this device is a forming mold for a steel bar protective layer pad. When in use, the piston 3 moves inside the mold sleeve 2, so that the piston 3 contacts the limit frame 202 at the bottom of the mold sleeve 2. The contact makes the tapered groove ring 301 fit with the tapered groove 201, which can provide a forming space for the steel bar protective layer pad. At the same time, a tapered groove 201 is designed in the sleeve 2, and a side wall inclined design is adopted. By utilizing an inverted cone shape, the piston 3 only needs to move slightly by one millimeter to be ejected from the inside of the molding cavity of the sleeve 2, which is convenient for demolding. After the molding operation is completed, the plug 302 is pushed to push the piston 3 out of the steel bar protective layer pad to complete the demolding. Because the top of the piston 3 is designed with a reinforcing rib 303, the structural strength of the piston 3 can be guaranteed while being thinner. The thickness of the piston 3 is designed to be within one millimeter, the friction is smaller, and the wear rate is lower after long-term use. The tapered groove design of the tapered groove 201 can better fit when in contact with the piston 3, improve stability, reduce fillet wear, and improve durability.
