Description

Technical Field

[0001] This utility model relates to the field of workpiece processing mold technology, and in particular to a thermal composite bottom mold structure with lettering. Background Technology

[0002] Existing hot-pressed, stretched products with labels are mainly divided into stretched hot-pressed and die-casting-imitation hot-pressed products. Die-casting-imitation hot-pressed products are generally produced by creating a blank and then hot-pressing the label along with the product. Stretched hot-pressed products are generally produced by hot-pressing an aluminum sheet into a blank, then cold-pressing the label, or locking the label onto a hot-pressing die with a gap between the label and the die. This method can easily cause problems such as broken or cracked lettering and label rings inside the product. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a thermal composite bottom mold structure with lettering.

[0004] This utility model is achieved through the following technical solution: a thermal composite bottom mold structure with lettering, including an upper mold and a lower mold located below the upper mold; the center of the composite bottom working surface of the upper mold is provided with a boss integrally formed therewith, and the surface of the boss is composited with lettering patterns integrally formed therewith by an electrical discharge machining process using a spark machine.

[0005] The lettering pattern is applied to the boss using an electrical discharge machining process. The lettering, boss, and upper mold are integrally formed, which avoids gaps between the lettering and the upper mold that could cause lettering marks, prevents screws from loosening and falling off, and eliminates the risk of accidents caused by loose lettering falling off.

[0006] The lettering pattern is a groove that extends from the lower side of the boss into the inside of the boss.

[0007] The lower side of the upper mold is provided with a ring-shaped groove, which is located on the outer periphery of the boss and is concentric with the boss. The ring-shaped groove forms a sealing range for the thermally bonded product, and the outer side of the groove acts as a seal to prevent gaps from occurring when the substrate and the aluminum alloy are bonded.

[0008] The height difference between the lower side of the boss and the annular groove is 0.6±0.1mm.

[0009] The depth difference between the lettering pattern and the lower side of the boss is 0.4±0.1mm.

[0010] Compared with the existing technology, the advantages of this utility model are: the mold has a simple structure, the lettering, the boss and the upper mold are integrated into one structure, which completely solves the problem of lettering ring printing, reduces the frequency of lettering breakage and chipping, improves production efficiency, and eliminates the problem of work accidents caused by loosening and falling of lettering.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] Example

[0016] See Figures 1 to 2 It is a thermal composite bottom mold structure with lettering, including an upper mold 1 and a lower mold located below the upper mold 1; the center of the composite bottom working surface of the upper mold 1 is provided with a boss 2 integrally formed therewith, and the surface of the boss 2 is composited with lettering patterns 3 integrally formed therewith by an electrical discharge machining process using a spark machine.

[0017] The lettering pattern 3 is applied to the boss 2 using an electrical discharge machining process. The lettering, boss 2, and upper mold 1 are integrally formed, which avoids gaps between the lettering and upper mold 1 that could cause lettering marks, prevents screws from loosening and falling off, and eliminates the problem of loose lettering falling off and causing operational accidents.

[0018] The letter mark pattern 3 is a pattern that is recessed from the lower side of the boss 2 into the inside of the boss 2.

[0019] The lower side of the upper mold 1 is provided with a ring-shaped groove 4, which is located on the outer periphery of the boss 2 and is co-centered with the boss 2. The ring-shaped groove 4 forms the sealing range of the thermally laminated product, and the outer side of the groove acts as a sealing agent to prevent gaps from occurring when the base plate and the aluminum alloy are bonded.

[0020] The height difference between the lower side of the boss 2 and the annular groove 4 is 0.6±0.1mm. In this embodiment, the height difference is preferably 0.6mm.

[0021] The depth difference between the lettering pattern 3 and the lower side of the boss 2 is 0.4±0.1mm. In this embodiment, the depth difference is preferably 0.4mm.

[0022] In this embodiment, the boss 2 in the middle of the upper mold 1 is machined by a CNC lathe. By machining an annular groove 4 on the lower side of the upper mold 1, a boss 2 is formed in the center of the working surface of the composite bottom.

[0023] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the present utility model should be included in the patent scope of this case.
