Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] Example: Reference Figure 1-4 A ceramic heating plate forming mold shown in the figure comprises a base 1 and an upper base 2, a bottom mold 3 is embedded in the base 1, an upper mold 4 is detachably fixed to the lower end of the upper base 2 through a connecting piece, and the bottom mold 3 and the upper mold 4 are adapted to each other;

[0024] A molding groove 12 is provided at the upper end of the base 1, and the bottom mold 3 is located at the bottom of the molding groove 12. An inclined surface 13 inclined outward is provided on the peripheral side of the molding groove 12.

When the upper mold 4 and the bottom mold 3 are cooperated for die-casting, the peripheral side of the upper mold 4 is sealed against the inclined surface 13.

[0025] Based on the above structure, firstly, by detachably connecting the bottom mold 3 to the base 1 and detachably connecting the upper mold 4 to the upper seat 2, it is possible to perform molding operations on different ceramic heating plates by replacing the bottom mold 3 and the upper mold 4. Compared with directly replacing the entire mold, replacing the die head (i.e., the bottom mold 3 and the upper mold 4) can further save mold costs, thereby reducing the mold use costs in various ceramic heating plate molding operations;

[0026] Secondly, by setting the inclined surface 13, the contact area and contact time between the upper mold 4 and the base 1, the base 1 and the bottom mold 3, and the finished or semi-finished ceramic heating plate and the base 1 can be reduced during the processes of mold closing, mold separation, disassembly of the bottom mold 3 and taking out the finished product, thereby reducing the friction loss between the base 1, the bottom mold 3, the upper mold 4 and the finished ceramic heating plate. This not only extends the service life of the ceramic heating plate molding mold, but also improves the yield rate of the finished ceramic heating plate and reduces the loss cost in the production process.

[0027] Furthermore, a mounting column 5 is fixed to the periphery of the bottom mold 3 , and one side of the mounting column 5 is provided with an inclined portion inclined at the same angle as the inclined surface 13 , and a column groove 14 for engaging with the mounting column 5 is opened on the side wall of the molding groove 12 .

[0028] Furthermore, an ear plate 51 is fixed to the upper end of the mounting column 5, and a notch 15 is provided at the upper end of the base 1 for snap-fitting with the ear plate 51. The notch 15 extends from the end of the ear plate 51 and extends to the outside of the base 1. The ear plate 51 is arranged to facilitate the removal of the bottom mold 3, or the die-cast ceramic heating plate product can be removed by pulling the bottom mold 3, thereby facilitating the rapid replacement of the bottom mold 3 and the removal of the finished product, thereby improving production efficiency.

[0029] Furthermore, the notch 15 is provided with an anti-foolproof portion 151 protruding inward, and the ear plate 51 is provided with an anti-foolproof edge 511 concave inward, and the anti-foolproof edge 511 is matched with the anti-foolproof portion 151.

[0030] Furthermore, the connecting member includes a connecting bolt 6 , the upper end of which movably passes through the upper seat 2 and is threaded with a nut, and the lower end of the connecting bolt 6 is fixed to the upper end of the upper mold 4 .

[0031] Further, the base 1 is provided with an installation cavity 11, and a cooling coil 7 and an electric heating plate 8 are installed in the installation cavity 11. The electric heating plate 8 is fixed on the inner top wall of the installation cavity 11 corresponding to the bottom wall of the forming groove 12, and an upwardly extending electric heating frame 81 is arranged around the electric heating plate 8. The electric heating frame 81 is coated on the inner side wall of the installation cavity 11 corresponding to the surrounding side of the forming groove 12.

The cooling coil 7 is connected to the external cooling mechanism through a pipeline, and the electric heating plate 8 is connected to an external power supply;

[0032] Through the setting of the cooling coil 7, the electric heating plate 8 and the electric heating frame 81, the staff can control the cooling coil 7 or the electric heating plate 8 to control the cooling coil 7 to quickly cool down the finished ceramic heating plate in the ceramic heating plate forming mold to promote molding, or use the electric heating plate 8 and the electric heating frame 81 to heat the ceramic heating plate forming mold to ensure the smooth progress of the molding operation, thereby further improving production efficiency and product quality.

[0033] Working principle of the utility model: in daily use, the bottom mold 3 is detachably connected to the base 1, and the upper mold 4 is detachably connected to the upper seat 2, so that different ceramic heating plates can be formed by replacing the bottom mold 3 and the upper mold 4. Compared with directly replacing the entire mold, replacing the die head can further save the mold cost, thereby reducing the mold use cost in the molding operation of various ceramic heating plates;

[0034] By setting the inclined surface 13, the contact area and contact time between the upper mold 4 and the base 1, the base 1 and the bottom mold 3, and the finished or semi-finished ceramic heating plate and the base 1 can be reduced during the processes of mold closing, mold separation, disassembly of the bottom mold 3, and taking out the finished product, thereby reducing the friction loss between the base 1, the bottom mold 3, the upper mold 4, and the finished ceramic heating plate. This can not only extend the service life of the ceramic heating plate molding mold, but also improve the yield rate of the finished ceramic heating plate, and reduce the loss cost in the production process;
