Description

Technical Field

[0001] The utility model belongs to the technical field of lining plate moulds, and in particular relates to a steel-rubber composite lining plate tear-proof mould. Background Art

[0002] Steel-rubber composite lining mold is a mold made of steel plate and rubber material, used in specific mechanical or engineering applications. It combines the strength of steel plate with the elasticity and wear resistance of rubber material, and has a wide range of application prospects.

[0003] The existing steel-rubber composite lining molds have gaps designed at the joints of the parts. The designed gaps can ensure that the parts can maintain good splicing and operation when the materials expand and contract or other environmental conditions change, avoiding excessive stress or damage in the close-fitting parts due to slight size changes. At the same time, reasonable gap design can simplify the assembly process, making the parts easier to align and install during assembly, thereby improving assembly efficiency and reducing human errors in assembly.

[0004] However, at different temperatures, the material will expand and contract due to heat, resulting in slight changes in size, which will widen the designed gap. Similarly, parts will wear or deform due to frequent use or environmental factors, causing the originally designed gap to gradually increase. The increase in the gap between mold parts will cause serious tearing of the product, thereby increasing the difficulty of repairing the product. Utility Model Content

[0005] In order to solve the technical problem that product tearing is serious and the difficulty of repairing the product is increased, the utility model provides a steel-glue composite liner anti-tear mold.

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

[0007] A steel-rubber composite liner tear-proof mold, comprising a lower concave mold, wherein the upper side of the lower concave mold is provided with symmetrically arranged chamfered C corners;

[0008] A lower template is arranged below the lower concave die, a mounting groove is opened in the middle of the upper part of the lower template, the lower concave die is inserted in the mounting groove, and the lower concave die is installed on the lower template.

[0009] Preferably, the chamfered C angle is set between C5-C10.

[0010] Preferably, a first arcuate surface is provided on the lower side of the lower concave mold, and a second arcuate surface is provided on the upper side of the lower mold plate at a position corresponding to the mounting groove, and the first arcuate surface and the second arcuate surface are used in conjunction with each other.

[0011] Preferably, the lower template is provided with two groups of symmetrically arranged expansion grooves on the two short surfaces corresponding to the lower concave mold, and positioning blocks are slidably connected in the expansion grooves. Two groups of symmetrically arranged positioning grooves are provided at the positions corresponding to the positioning blocks below the lower concave mold. The shape of the positioning grooves corresponds to the shape of the positioning blocks, and the positioning blocks are inserted in the positioning grooves.

[0012] Preferably, symmetrically arranged springs are connected between the positioning block and the lower template, and symmetrically arranged pull rods are connected to the side of the positioning block away from the positioning groove. The pull rods are located in the springs, and the pull rods are slidably connected in the lower template. Pull rings are connected to the ends of the two pull rods away from the positioning block.

[0013] Preferably, one end of the positioning block close to the lower die is trapezoidal.

[0014] Preferably, a third arcuate surface is provided above the positioning block near the positioning groove, and the third arcuate surface is used in conjunction with the first arcuate surface.

[0015] Beneficial effects of the utility model:

[0016] By setting a chamfered C angle on the upper side of the lower die, the gap at the original part joint can be effectively filled, especially at the edge position, which can reduce or eliminate the gap, thereby improving the sealing of the product. At the same time, it can reduce the concentration of stress at the edge, effectively prevent product tearing or other forms of defects caused by stress concentration, help improve the structural strength and durability of the product, ensure the stability of the product during use, and reduce the area and complexity of the repair, thereby simplifying the product surface repair process, making the repair work easier to carry out, and saving maintenance and repair costs.

[0017] By aligning the lower concave die with the installation groove and inserting it, after the bottom of the lower concave die contacts the bottom of the installation groove, the positioning block will correspond to the positioning groove, and under the action of the spring restoring force, the spring and the positioning block will be reset, so that the positioning block will be inserted into the positioning groove, and the installation and fixation of the lower concave die will be completed. By pulling the pull ring and the pull rod, the positioning block is moved out of the positioning groove and slides into the telescopic groove, so that the lower concave die can be unfixed, so that the lower concave die can be removed for maintenance. Compared with the existing use of bolts for fixing and removing, the bolts do not need to be installed and removed, which reduces the operation steps and saves time.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1 - Figure 7 As shown, a steel-rubber composite liner tear-proof mold comprises a lower concave mold 1, and a symmetrically arranged chamfered C corner 2 is provided at the upper side of the lower concave mold 1;

[0033] By setting the chamfered C angle 2, the following benefits can be provided: 1. It can effectively fill the gaps at the joints of the original parts, especially at the edge positions, and can reduce or eliminate the gaps, thereby improving the sealing of the product;

[0034] Second, it can reduce the concentration of stress at the edge, effectively prevent product tearing or other forms of defects caused by stress concentration, help improve the structural strength and durability of the product, and ensure the stability of the product during use;

[0035] 3. It can reduce the area and complexity of the repair area, thereby simplifying the repair process of the product surface, making the repair work easier and saving maintenance and repair costs.

[0036] The chamfered C angle 2 is set between C5 and C10. Through this setting, the chamfered C angle 2 within this range can not only ensure the structural strength of the mold, but also effectively reduce the gap at the joint of parts, thereby improving the stability and durability of the product. A chamfered C angle 2 that is too small may not fully solve the problem of joint gap, while a chamfered C angle 2 that is too large may cause new structural problems or processing difficulties. The chamfered C angle 2 design of C5-C10 can ensure that the gap at the joint of parts is effectively controlled during mold manufacturing and use, reducing the possibility of tearing or other appearance defects in the product.

[0037] A lower template 11 is provided below the lower concave die 1, the lower concave die 1 is mounted on the lower template 11, and the lower template 11 is used to install and fix the lower concave die 1;

[0038] A mounting groove 12 is provided in the middle of the upper part of the lower template 11, and the lower concave mold 1 is inserted into the mounting groove 12, and the mounting groove 12 is used to position the lower concave mold 1;

[0039] A first arc surface 13 is provided on the lower side of the lower die 1, and a second arc surface 14 is provided on the upper side of the lower template 11 at a position corresponding to the mounting groove 12. The first arc surface 13 and the second arc surface 14 are used together, so that when the lower die 1 is inserted into the lower template 11, the lower die 1 can be accurately inserted into the mounting groove 12. At the same time, the insertion of the lower die 1 into the mounting groove 12 will be smoother, reducing the resistance during insertion;

[0040] The lower mold plate 11 is provided with two sets of symmetrically arranged telescopic grooves 3 on two short sides corresponding to the lower concave mold 1, for accommodating the spring 32 and the positioning block 31;

[0041] A positioning block 31 is slidably connected in the telescopic groove 3 to fix the lower die 1;

[0042] Two groups of symmetrically arranged positioning grooves 311 are provided at the positions corresponding to the positioning blocks 31 below the lower concave die 1. The shapes of the positioning grooves 311 correspond to the shapes of the positioning blocks 31. The positioning blocks 31 are inserted into the positioning grooves 311. The positioning blocks 31 cooperate with the positioning grooves 311 to install and fix the lower concave die 1.

[0043] The end of the positioning block 31 close to the lower concave die 1 is trapezoidal. The trapezoidal design allows the positioning block 31 to gradually engage when inserted into the positioning groove 311, thereby reducing friction during plugging, reducing resistance during plugging, and making plugging smoother. At the same time, the contact area between the positioning block 31 and the positioning groove 311 can be enlarged, so that the positioning block 31 is fixed more tightly in the positioning groove 311, thereby improving the connection strength and stability of the lower concave die 1.

[0044] A third arc surface 4 is provided above the positioning block 31 near the positioning groove 311. The third arc surface 4 is used in conjunction with the first arc surface 13. By providing the third arc surface 4, during the process of inserting the lower concave die 1 into the installation groove 12, the lower concave die 1 can squeeze the positioning block 31 without hindrance, so that the positioning block 31 slides into the telescopic groove 3, and finally the positioning block 31 is inserted into the positioning groove 311.

[0045] A symmetrically arranged spring 32 is connected between the positioning block 31 and the lower template 11, and a symmetrically arranged pull rod 33 is connected to the side of the positioning block 31 away from the positioning groove 311. The pull rod 33 is located in the spring 32, and the pull rod 33 is slidably connected in the lower template 11. The ends of the two pull rods 33 away from the positioning block 31 are both connected to a pull ring 34;

[0046] When in use, align the lower die 1 with the mounting groove 12 and insert it. During the insertion process, the first arc surface 13 at the bottom of the lower die 1 will contact the third arc surface 4 above the positioning block 31, so that the lower die 1 squeezes the positioning block 31. After being squeezed, the positioning block 31 will slide into the telescopic groove 3. During the sliding process, the positioning block 31 will squeeze the spring 32. The spring 32 will shrink when squeezed and store the restoring force. After the bottom of the lower die 1 contacts the bottom of the mounting groove 12, the positioning block 31 will correspond to the positioning groove 311. Under the action of the restoring force of the spring 32, the spring 32 and the positioning block 3 1 will be reset, so that the positioning block 31 will be inserted into the positioning groove 311, and the lower concave mold 1 will be installed and fixed. In the use of the steel-rubber composite lining mold, the lower concave mold 1 needs to be regularly maintained. During maintenance, the lower concave mold 1 needs to be removed. When the lower concave mold 1 is removed, the positioning block 31 is moved out of the positioning groove 311 by pulling the pull ring 34 and the pull rod 33, and slides into the telescopic groove 3, so that the lower concave mold 1 loses its fixation, so that the lower concave mold 1 can be removed for maintenance. Compared with the existing use of bolts for fixing and removing, the bolts do not need to be installed and removed, which reduces the operation steps and saves time.
