Description

Technical Field

[0001] This invention belongs to the field of mold technology, and in particular relates to a mold repair tool and its usage method. Background Technology

[0002] In the mold industry, molds are various molds and tools used to obtain desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the material being molded.

[0003] During use, molds inevitably suffer various types of damage, such as cracking, chipping, and deformation. After damage, molds are selected based on the specific damage. Molds that are still repairable are repaired and then reused. During repair, support similar to that used in construction formwork is needed on the inside of the mold to prevent molten liquid from overflowing and to achieve a fixed and restrained effect. Currently, iron plates are used for support, but there are problems with supporting the corners of the iron plates. To achieve the best support effect, support is needed at least in the middle and corners of the iron plate. However, this method requires a large space for the entire support component, and it becomes even more difficult when the repair location is on two or more adjacent surfaces. If the best support effect is not considered and some corners are left unsupported, relying solely on the strength of the iron plate, there will be large gaps at the corners, resulting in significant protrusions inside the mold after repair, requiring more time for grinding and finishing. Therefore, it is necessary to propose a tool that can provide comprehensive and reliable support for the iron plate at the repair location during mold repair, in order to solve the problem of poor support effect for the iron plate during current mold repair. Summary of the Invention

[0004] In view of this, the present invention aims to provide a mold repair tool and its usage method to solve the problem in the prior art that it cannot provide comprehensive and reliable support for the iron plate at the repair location during repair.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mold repair tool is provided, wherein a tool body is provided in the repair area of ​​the mold, the tool body includes a positioning plate and a support member, a power plug is installed on the rear side of the positioning plate, an electrorheological fluid electrically connected to the power plug is provided inside the positioning plate, the outer end face of the positioning plate contacts the iron plate in the repair area, and the inner end face of the positioning plate is symmetrically installed on both sides, the other end of the support member is connected to the inner wall of the mold.

[0006] Furthermore, the positioning plate is provided with interconnected horizontal and vertical grooves, which are filled with electrorheological fluid.

[0007] Furthermore, the positioning plate is hollow, and the positioning plate contains a mesh of conductive wires arranged in both directions, which the power supply plug is connected to.

[0008] Furthermore, the positioning plate is made of rubber or other flexible materials.

[0009] Furthermore, the positioning plate is made of rubber with a Shore hardness of less than 10.

[0010] Furthermore, the support member includes a first support rod and a second support rod. A threaded rod is installed on the inner end of the first support rod, and the threaded rod is connected to the inner end of the second support rod. The outer end of the first support rod is connected to the positioning plate, and the outer end of the second support rod is connected to the inner wall of the mold.

[0011] Furthermore, end plates are installed at the connection points of the first support rod and the positioning plate, as well as the connection points of the second support rod and the mold, via connecting seats.

[0012] Furthermore, the connector is made of rubber or other flexible materials.

[0013] Furthermore, the outer side of the end plate is uniformly provided with recessed holes.

[0014] Furthermore, the inner side of the positioning plate is uniformly provided with the same number of protruding balls as the concave holes.

[0015] A method for using a mold repair tool includes the following steps: Step 1: Place the iron plate in the repair area, and then attach the positioning plate to the iron plate; Step 2: Press the positioning plate firmly against the iron plate; Step 3: Power is supplied through the power plug, and the electrorheological fluid inside the positioning plate changes from liquid to solid; Step 4: Use support members to support the positioning plate; Step 5: After confirming that the positioning plate and the inner wall of the mold form a support, repair the repair area.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes the characteristic of electrorheological fluid to change from liquid to fixed state by increasing its internal viscosity under the action of an electric field. By placing it inside the positioning plate, the shape of the positioning plate can be arbitrarily changed, making it fully adaptable to various different shapes and structures of the mold repair position. It can simultaneously meet the support effect for repairing iron plates on two or more adjacent surfaces, providing more comprehensive support and better support effect.

[0017] 2. The support component of this invention has adjustable support length through the support rods that are connected by threads, which can meet the support needs in a larger support space and improve the flexibility of use. At the same time, the soft connecting seat also makes the support position of the support component no longer limited, and can be adjusted in the mold according to the specific situation, further improving the flexibility of use.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0021] See Figure 1-6This embodiment describes a mold repair tool. A tool body 1 is provided at the repair area 21 of the mold 2. The tool body 1 includes a positioning plate 11 and support members 12. A power plug 111 is installed on the rear side of the positioning plate 11. An electrorheological fluid electrically connected to the power plug 111 is provided inside the positioning plate 11. The outer end face of the positioning plate 11 contacts an iron plate at the repair area 21. Support members 12 are symmetrically installed on both sides of the inner end face of the positioning plate 11. The other end of the support member 12 is connected to the inner wall of the mold 2. The positioning plate 11 has interconnected transverse grooves 112 and longitudinal grooves 113, which are filled with electrorheological fluid. The positioning plate 11 is hollow and contains a mesh of conductive wires arranged longitudinally and transversely. The power plug 111 is connected to the conductive wires.

[0022] First, the iron plate is placed inside the mold 2 to restrict and support the repair area 21. Then, the positioning plate 11 is attached to the iron plate and pressed to make it fit tightly against the iron plate, or the iron plate is used to cover two or more adjacent surfaces. After completion, power is supplied through the power plug 111. Under the action of the electric field, the viscosity of the electrorheological fluid inside the positioning plate 11 increases, causing it to change from a liquid to a solid. Then, the support member 12 is used for support. First, one side of the support member 12 is placed against the positioning plate 11, and the other side is moved to the required support point inside the mold 2, ensuring that the support member 12 forms abutment support against the positioning plate 11 and the inner wall of the mold 2. At this time, the repair area 21 can be repaired. Whether it is a flat, curved single surface or multiple adjacent surfaces, the support effect can be met, providing more comprehensive support and better support effect.

[0023] The positioning plate 11 is made of rubber or other flexible materials, which facilitates the deformation of the positioning plate 11.

[0024] Specific Implementation Method Two: See Figure 1-6 In this embodiment, the support member 12 includes a first support rod 122 and a second support rod 123. A threaded rod 124 is installed at the inner end of the first support rod 122, and the threaded rod 124 is connected to the inner end of the second support rod 123. The outer end of the first support rod 122 is connected to the positioning plate 11, and the outer end of the second support rod 123 is connected to the inner wall of the mold 2. End plates 121 are installed at the connection points of the first support rod 122 and the positioning plate 11, and the connection points of the second support rod 123 and the mold 2, respectively, through connecting seats 125. The connecting seats 125 are made of rubber or other flexible materials.

[0025] When using the support member 12 for support, first abut one end plate 121 against the positioning plate 11, then move the other end plate 121 to the required support point inside the mold 2, and then rotate the second support rod 123 so that it extends in length through the threaded relationship with the threaded rod 124, ensuring that the end plate 121 forms abutment support against the positioning plate 11 and the inner wall of the mold 2. Through the mutually threaded support rods, the support member 12 has the function of adjustable length, which is convenient for the support needs in a larger support space and improves the flexibility of use. The connecting seat 125, which is made of rubber or other soft materials, also makes the support position of the support member 12 no longer limited, and can be adjusted by itself in the mold 2 according to the specific situation, further improving the flexibility of use.

[0026] Specific implementation method three: See Figure 1-6 In this embodiment, the outer side of the end plate 121 is uniformly provided with recessed holes 126, and the inner side of the positioning plate 11 is uniformly provided with the same number of protruding balls 114 as the recessed holes 126. The positioning plate 11 is supported by the cooperation between the protruding balls 114 and the recessed holes 126.

[0027] Detailed Implementation Method Four: See [link] Figure 1-6 This embodiment describes a method for using a mold repair tool, which includes the following steps: Step 1: Place the iron plate in the repair area 21, and then attach the positioning plate 11 to the iron plate; Step 2: Press the positioning plate 11 firmly against the iron plate; Step 3: Power is supplied to the conductive wire in the positioning plate 11 through the power supply plug 111. Under the action of the electric field, the viscosity of the electrorheological fluid in the positioning plate 11 increases, and the electrorheological fluid in the positioning plate 11 changes from liquid to solid. Step 4: Use the support member 12 to support the positioning plate 11. First, place one end plate 121 against the positioning plate 11, then move the other end plate 121 to the required support point inside the mold 2. Then rotate the second support rod 123 so that it can extend its length through the threaded relationship with the threaded rod 124. Step 5: After confirming that the positioning plate 11 and the inner wall of the mold 2 form abutting support, repair the repair area 21.
