Description

Technical Field

[0001] This utility model relates to the field of mold arc surface cutting technology, specifically a tire mold arc surface cutting device. Background Technology

[0002] In industrial production, especially in product prototype development, sculptural art, or composite material mold manufacturing, spherical foam materials are often used to create product models or casting master molds. This process frequently requires the creation of upper and lower mold bodies with precise, smooth curved contours.

[0003] Currently, in existing technologies, the production of such foam-type R-arcs, especially complex irregular curved surfaces, is generally carried out using CNC machine tools. However, this equipment has high processing costs and a large footprint, making it unsuitable for small and medium-sized enterprises to produce molds in small batches, and its application scope is narrow. Utility Model Content

[0004] To address the technical problems mentioned above, this utility model provides a tire mold arc surface cutting device.

[0005] The technical solution of this utility model is as follows: A tire mold arc surface cutting device, comprising: power supply; A voltage regulator includes an input terminal and two output terminals, with its input terminal electrically connected to a power supply. An insulating support includes two symmetrically arranged insulating long plates, which are detachably connected by an insulating connector. The heating wire has its two ends clamped between two insulating supports and distributed at both ends of the insulating supports. The two ends of the heating wire are electrically connected to the two output ends of the voltage regulator through wires. The shape of the heating wire is adapted to the preset curvature of the tire mold to be formed. An insulating guide is vertically installed at one end of the insulating support; Both ends of the insulating long plate are provided with mounting grooves, and the mounting grooves of the two insulating long plates are set accordingly, forming mounting holes to accommodate the heating wire end and the output end.

[0006] The specific structure of the mounting slot is as follows: the mounting slot includes a connected heating wire slot and an output end slot. The heating wire slot and the output end slot are arranged along the width direction of the insulating plate. Both the heating wire slot and the output end slot have an opening at opposite ends.

[0007] Furthermore, both the heating wire slot and the output end slot are semi-circular slots, with the diameter of the heating wire slot being smaller than the diameter of the output end slot.

[0008] Furthermore, the mounting holes include heating wire holes and output terminal holes.

[0009] To facilitate the connection between the heating wire and the insulating bracket, as well as the connection between the heating wire and the output terminal, an insulating connector is inserted into the mounting hole. The insulating connector includes an upper sleeve and a lower sleeve arranged coaxially. The outer diameter of the upper sleeve is adapted to the output terminal hole, the outer diameter of the lower sleeve is adapted to the heating wire hole, and the inner diameter of the lower sleeve is adapted to the outer diameter of the heating wire. The end of the heating wire is connected to the upper sleeve.

[0010] Furthermore, the upper end of the sleeve is provided with a sealing plate, which has two through holes. The inner diameter of the through holes is the same as the inner diameter of the heating wire, and the end of the heating wire can be fixed by passing through the two through holes.

[0011] To facilitate the protection of the heating wire tip and wires, a protective cap is provided on the upper port cover of the output end hole.

[0012] To prevent the wires connected to the heating wire from protruding outside the insulating bracket and affecting the cutting of the foam material by the heating wire, the two insulating plates are provided with wire harness grooves along their length. The wire harness grooves connect to the two output end holes of the insulating bracket, and the wires are located inside the wire harness grooves.

[0013] The specific structure of the insulating guide is as follows: the insulating guide is an elongated seat, and a non-circular through hole adapted to the insulating bracket is opened on the upper part of the elongated seat. The connector passes through the elongated seat to connect two insulating long plates.

[0014] To facilitate workers in using a handheld cutting device to cut curved surfaces on circular foam material, an operating handle is provided on the upper surface of the insulating long plate, and the operating wrench is located near the insulating guide.

[0015] The beneficial effects of this utility model are as follows: By using an electric heating wire that matches the preset curvature of the tire mold as a cutting tool, the expensive and complex CNC machine tool is replaced, greatly reducing equipment investment and processing costs. The cutting tool can be used by hand and has a simple structure. It can quickly heat-melt cut round foam materials, greatly shortening the mold prototype manufacturing cycle. It is especially suitable for the rapid R&D and small-batch trial production needs of small and medium-sized enterprises.

[0016] By setting up an insulating bracket consisting of two insulating long plates connected by a detachable connector, and opening corresponding mounting grooves at both ends of the long plates, mounting holes for accommodating the end of the heating wire and the wire are formed, making the installation, tensioning and replacement of the heating wire extremely convenient.

[0020] See Figure 4 and Figure 5 As shown, the insulating bracket 3 includes two symmetrically arranged insulating long plates 31, which are detachably connected by an insulating connector 4. Each end of the insulating long plate 31 has a mounting groove, and the mounting grooves of the two insulating long plates 31 are correspondingly arranged, forming mounting holes to accommodate the ends of the heating wire 5 and the output end 22. The insulating bracket 3 has two mounting holes.

[0021] The mounting slot has the following structure: it includes a connected heating wire slot 311 and an output end slot 312. Therefore, the mounting holes include holes for the heating wire 5 and output end 22. The heating wire slot 311 and the output end slot 312 are arranged along the width of the insulating plate 31, and each has an opening at one opposite end. Both the heating wire slot 311 and the output end slot 312 are semi-circular slots, with the diameter of the heating wire slot 311 being smaller than the diameter of the output end slot 312. The semi-circular design of the heating wire slot 311 and the output end slot 312, in conjunction with the insulating connector 7, effectively clamps and fixes heating wires 5 and wires 10 of different diameters, ensuring the stability and safety of the electrical connection, avoiding localized overheating or power outages due to poor contact, and guaranteeing the continuous stability of the cutting process.

[0022] The heating wire 5 is clamped between two insulating supports 3 at both ends and distributed at both ends of the insulating supports 3. The heating wire 5 is electrically connected to the two output terminals 22 of the voltage regulator 2 via wires 10. The shape of the heating wire 5 matches the preset curvature of the tire mold to be formed. After the heating wire 5 is bent into shape according to the contour of the tire mold, the power supply 1 can be connected for cutting. The heating wire 5 can be bent into shape according to the contour of the tire mold after the insulating supports 3 are installed, or it can be bent into shape first and then installed on the insulating supports 3, depending on the actual situation. The contour of the tire mold to be formed can be an existing mold contour, or the heating wire 5 can be bent into shape according to a 1:1 printed drawing or other matching products.

[0023] An insulating guide 6 is vertically disposed at one end of an insulating support 3; the insulating guide 6 is an elongated seat, and a non-circular through hole 61 adapted to the insulating support 3 is provided on the upper part of the elongated seat. The connector 4 passes through the elongated seat to connect two insulating plates 31.

[0024] See Figure 6 As shown, to facilitate the connection between the heating wire 5 and the insulating bracket 3, and the connection between the heating wire 5 and the output terminal 22 via the wire 10, an insulating connector 7 is inserted into the mounting hole. The insulating connector 7 includes an upper sleeve 71 and a lower sleeve 72 arranged coaxially. The outer diameter of the upper sleeve 71 is adapted to the hole of the output terminal 22, the outer diameter of the lower sleeve 72 is adapted to the hole of the heating wire 5, and the inner diameter of the lower sleeve 72 is adapted to the outer diameter of the heating wire 5. The end of the heating wire 5 is connected to the upper sleeve 71.

[0025] The upper end of the sleeve is provided with a sealing plate 73, and the sealing plate 73 has two through holes 731. The inner diameter of the through holes 731 is the same as the inner diameter of the heating wire 5. The end of the heating wire 5 can be fixed by passing through the two through holes 731.

[0026] To facilitate the protection of the end of the heating wire 5 and the wire 10, a protective cap 8 is provided on the upper port of the output end 22 hole.

[0027] Both insulating plates 31 are provided with wire-binding grooves 313 along their length. The wire-binding grooves 313 are connected to the two output end holes 22 of the insulating bracket 3, and the wires 10 are located in the wire-binding grooves 313. The wire-binding grooves 313 arranged along the length of the insulating plates 31 can neatly store the wires 10 in the grooves, effectively preventing the wires 10 from being exposed and entangled or burned with the material being cut, thus improving operational safety.

[0028] To facilitate workers to use a hand-held cutting device to cut curved surfaces on circular foam material, an operating handle 9 is provided on the upper surface of the insulating long plate 31, and the operating wrench is located near the insulating guide 6.
