Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a preheating processing mold for LED brackets. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, forging, and stamping. Therefore, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of objects by changing the physical state of the material being molded.

[0003] Existing mold preheating typically involves heat transfer through contact between internal oil pipes and the mold cavity, bringing the cavity surface to the preset processing temperature. This is achieved by connecting several oil pipe joints and interconnecting them with heat-conducting oil pipes. Since the heat-conducting oil pipes and joints are usually threaded, each joint needs to be tightened or loosened during installation or removal, resulting in time-consuming assembly and disassembly.

[0004] For thinner bending materials (sheets of 0.1 to 0.5 mm), preheating does not require a long time, and only the bending part needs to be preheated. If a heat-conducting oil pipe is used for preheating, the entire material will be preheated, which increases the cost of the mold and makes disassembly and assembly time-consuming and laborious.

[0005] Therefore, it is necessary to propose a preheating processing mold for LED brackets to preheat the bending parts of the material, while facilitating installation and reducing costs. Utility Model Content

[0006] To address the aforementioned issues, this invention proposes a preheating processing mold for LED brackets to preheat the bent portions of the material, while also facilitating installation and reducing costs.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model proposes a preheating processing mold for LED brackets, including an upper mold and a lower mold. The upper mold and the lower mold are connected to form a mold. The lower mold includes a mold blank, an electric heating component, a bending and pushing component, and a fixing base. The mold blank is fixedly connected to the upper surface of the fixing base. The mold blank is provided with a placement groove and an ejection groove. The ejection groove is located on the bottom wall of the placement groove and communicates with the placement groove. The electric heating component is fixedly connected to the bottom of the placement groove and close to the ejection groove.

[0009] Furthermore, the mold blank is provided with an installation groove, which is located on the bottom wall of the placement groove and on one side of the ejection groove. The electric heating component is housed in the installation groove, and the upper surface of the electric heating component is flush with the bottom wall of the placement groove.

[0010] Furthermore, the electric heating assembly includes a contact heating component and a fixing bolt. The contact heating component is housed in the mounting groove. One end of the fixing bolt passes through the contact heating component from one side of the mold blank, and the other end of the fixing bolt is fixedly connected to the mold blank.

[0011] Furthermore, a fixing groove is provided on one side of the mold blank, the fixing groove is connected to the mounting groove, and one end of the fixing bolt is received in the fixing groove.

[0012] Furthermore, a plug-in groove is provided on one side of the mounting groove. The plug-in groove is connected to the mounting groove. The plug-in groove is aligned with the fixing groove and is away from the fixing groove. One end of the fixing bolt passes through the contact heating component and is inserted into the plug-in groove.

[0013] Furthermore, the contact heating component includes a ceramic shell and a heating rod. The heating rod is embedded in the ceramic shell and flush with the upper surface of the ceramic shell. The ceramic shell is housed in the mounting groove. One end of the fixing bolt passes through the ceramic shell from one side of the mold blank.

[0014] Furthermore, the bottom of the ceramic shell is provided with a bolt groove, and one end of the fixing bolt is provided with a bolt rod, which passes through the bolt groove.

[0015] Furthermore, the ceramic shell has a rectangular structure.

[0016] Furthermore, the bending push assembly includes a drive device and a push rod assembly. The drive device is fixedly connected to the fixed base. One end of the push rod assembly is connected to the rotating shaft of the drive device as a lead screw. The other end of the push rod assembly extends into the ejection groove and is slidably connected to the ejection groove.

[0017] Furthermore, there are multiple ejector slots and multiple electric heating components. Each of the multiple electric heating components corresponds to one of the multiple ejector slots. One end of the push rod assembly is provided with an ejector end that is the same number as the ejector slots. Each of the multiple ejector ends corresponds to one of the multiple ejector slots. The ejector end is received in the ejector slot and is slidably connected to the slot wall of the ejector slot.

[0018] The beneficial effects of this utility model are:

[0019] This invention employs an electric heating component installed at the bottom of the placement groove of the mold blank, near the ejector groove. This allows the LED bracket to be placed in the placement groove before bending. The electric heating component, when energized, preheats the area to be bent, softening it.

[0032] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0033] Please refer to Figures 1-8 This utility model proposes a preheating processing mold for LED brackets, including an upper mold 1 and a lower mold 2. The upper mold 1 and the lower mold 2 are connected to form a mold. The lower mold 2 includes a mold blank 21, an electric heating component 22, a bending and pushing component 23, and a fixed base 24. The electric heating component 22 and the bending and pushing component 23 are electrically connected to an external controller. The external controller issues corresponding operating commands to the electric heating component 22 and the bending and pushing component 23, so that the electric heating component 22 and the bending and pushing component 23 perform corresponding operations. The mold blank 21 is fixedly connected to the upper surface of the fixed base 24. The mold blank 21 is provided with a placement groove 211 and an ejection groove 212. The ejection groove 212 is located on the bottom wall of the placement groove 211 and is connected to the placement groove 211. The electric heating component 22 is fixedly connected to the bottom of the placement groove 211 and close to the ejection groove 212. One end of the bending and pushing component 23 is fixedly connected to the fixed base 24, and the other end of the bending and pushing component 23 extends into the ejection groove 212.

[0034] In this embodiment, the electric heating component 22 is directly installed at the bottom of the placement groove 211 of the mold blank 21 and close to the ejector groove 212. This facilitates the direct transfer of heat to the part of the LED bracket 3 to be bent. The LED bracket 3 is a thin sheet metal structure with a thickness in the range of 0.1 to 0.5 mm. Before bending, the LED bracket 3 can be placed in the placement groove 211. After placement, the part to be bent comes into contact with the electric heating component 22. Then, the electric heating component 22 is powered on and heats up, transferring the heat to the part to be bent to preheat it, so that the part to be bent in the LED bracket 3 is softened by the heat. Then, when bending, the bending push component 23 pushes the part to be bent out of the ejector groove 212 at a preset angle to be bent, forming a bent part. The electric heating component 22 only needs to be installed and powered on in the placement groove 211, which is convenient and quick.

[0035] In summary, this preheating processing mold for LED brackets can quickly preheat the bent parts of the material, while also facilitating installation and reducing costs.

[0036] In this embodiment, the mold blank 21 is provided with a mounting groove 213. The mounting groove 213 is located on the bottom wall of the placement groove 211 and on one side of the ejection groove 212. The electric heating component 22 is housed in the mounting groove 213, and the upper surface of the electric heating component 22 is flush with the bottom wall of the placement groove 211. The mounting groove 213 is used to provide a storage space for the electric heating component 22. When installing the electric heating component 22, the electric heating component 22 is inserted into the mounting groove 213 and then fixed in the mounting groove 213. After fixing, the conductive wire of the electric heating component 22 is connected to an external controller.

[0037] In this embodiment, the electric heating component 22 includes a contact heating component 221 and a fixing bolt 222. The contact heating component 221 is housed in the mounting groove 213. One end of the fixing bolt 222 passes through the contact heating component 221 from one side of the mold blank 21, and the other end of the fixing bolt 222 is fixedly connected to the mold blank 21. The contact heating component 221 is used to preheat the part of the LED bracket to be bent. The fixing bolt 222 is used to fix the contact heating component 221 housed in the mounting groove 213. After the contact heating component 221 is placed into the mounting groove 213, it can be fixed by the fixing bolt 222 passing through the contact heating component 221 from one side of the mold blank 21. This installation method will not leave screw holes and fixing screws in the area of ​​the placement groove 211, and avoids the nuts scratching the surface of the LED bracket.

[0038] In this embodiment, a fixing groove 214 is provided on one side of the mold blank 21. The fixing groove 214 is connected to the mounting groove 213. One end of the fixing bolt 222 is received in the fixing groove 214. The fixing groove 214 is used to provide a space for the insertion of the fixing bolt 222, so that the fixing bolt 222 can be installed stably, and at the same time, the contact heating component 221 is fixed.

[0039] In this embodiment, a plug-in groove 2131 is provided on one side of the mounting groove 213. The plug-in groove 2131 is connected to the mounting groove 213. The plug-in groove 2131 is aligned with the fixing groove 214 and away from the fixing groove 214. One end of the fixing bolt 222 passes through the contact heating component 221 and is inserted into the plug-in groove 2131. The plug-in groove 2131 is designed so that one end of the fixing bolt 222 passes through the contact heating component 221 and is inserted into the plug-in groove 2131, so that both ends of the fixing bolt 222 can be fixed by force, thereby improving the fixing effect of the contact heating component 221.

[0040] In this embodiment, the contact heating component 221 includes a ceramic shell 2211 and a heating rod 2212. The heating rod 2212 is electrically connected to an external controller. The heating rod 2212 is embedded in the ceramic shell 2211 and flush with the upper surface of the ceramic shell 2211. The ceramic shell 2211 is housed in a mounting groove 213. One end of a fixing bolt 222 penetrates the ceramic shell 2211 from one side of the mold blank 21. The ceramic shell 2211 is used to insulate the side heat of the heating rod 2212, preventing the mold from overheating. The shell 2211 and the heating rod 2212 are assembled together before being installed in the mounting groove 213 to form a contact heating component 221. When installing it into the mounting groove 213, the heating rod 2212 is inserted into the mounting groove 213 with the ceramic shell 2212 facing upwards and the ceramic shell 2211 facing downwards. After the ceramic shell 2211 is inserted to the bottom of the mounting groove 213, one end of the fixing bolt 222 passes through the ceramic shell 2211 to fix the ceramic shell 2211, thereby installing the heating rod 2212 on one side of the ejector groove 212.

[0041] In this embodiment, the bottom of the ceramic shell 2211 is provided with a plug groove 22111, and one end of the fixing bolt 222 is provided with a plug rod 2221, which passes through the plug groove 22111. The plug rod 2221 is used to insert and fix the plug groove 22111 in the ceramic shell 2211, so that the ceramic shell 2211 is stably installed in the mounting groove 213. During installation, after the ceramic shell 2211 is placed at the bottom of the mounting groove 213, the plug groove 22111 will be aligned with the insertion groove 2131 and connected. At this time, the plug rod 2221 is inserted from the fixing groove 214, passes through the plug groove 22111 and enters the insertion groove 2131 to fix the ceramic shell 2211.

[0042] In this embodiment, the ceramic shell 2211 has a rectangular structure. The ceramic shell 2211 has the same structure as the mounting groove 213, which facilitates its adaptation and installation with the mounting groove 213.

[0043] In this embodiment, the bending push assembly 23 includes a drive device 231 and a push rod assembly 232. The drive device 231 is fixedly connected to the fixed base 24. One end of the push rod assembly 232 is connected to the rotating shaft of the drive device 231 as a lead screw, and the other end of the push rod assembly 232 extends into the ejection groove 212 and is slidably connected to the ejection groove 212. The drive device 231 is a stepper motor, which drives the lead screw to rotate and then drives the push rod assembly 232 to extend and retract. After the part of the LED bracket to be bent is preheated, the worker can issue a preset bending command to the drive device 231 through an external controller, so that the drive device 231 rotates a preset number of times and drives the push rod assembly 232 to slide in the direction of the ejection groove 212, so as to push and bend the part of the LED bracket to be bent by a preset angle.

[0044] In this embodiment, multiple ejector slots 212 and multiple electric heating components 22 are provided. Each of the multiple electric heating components 22 corresponds to one of the multiple ejector slots 212. One end of the push rod assembly 232 is provided with ejector ends 2321, which are the same number as the number of ejector slots 212. Each of the multiple ejector ends 2321 corresponds to one of the multiple ejector slots 212. The ejector ends 2321 are received in the ejector slots 212 and are slidably connected to the groove wall of the ejector slots 212. In order to accommodate the number of bending parts 31 of the LED bracket 3, the number of ejector slots 212 can be the same as the number of bending parts 31. Thus, the number of electric heating components 22 also needs to be the same as the number of ejector slots 212, so as to heat all the bending parts 31 in the LED bracket 3. After all the bending parts 31 have been heated, the multiple ejector ends 2321 can push out the bending parts 31 respectively to bend them.

[0045] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
