and a second lifting handle is arranged in the center of the top of the upper die.

Preferably, the electric heating rods are uniformly distributed at the bottom of the shell.

Preferably, the electric heating rod just can pass through the through hole.

Preferably, the scraping plate is movably connected with the lower die.

Advantageous effects

Compared with the prior art, the utility model has the advantages that the plastic mould with the uniform heating function can realize uniform heating by arranging the cavity in the lower mould, filling the cavity with the heat-conducting liquid and arranging the heating device in a ring shape; because the lower shell is of a fully sealed structure, heat is not easy to dissipate, energy is saved, and cost is reduced; the use of the portable heating column can uniformly heat the raw materials from top to bottom in the horizontal direction, thereby solving the problem of nonuniform heating of the existing plastic mold and improving the quality of products.

FIG. 2 is an enlarged view taken at A in FIG. 1;

FIG. 3 is a schematic structural view of an upper mold;

FIG. 4 is a top view of the hand held heating post;

in the above drawings: 1. the device comprises a base, a lower die, a heating rod, a ring-shaped heating device, a scraper plate, a liquid filling port, a balancing weight, a lifting handle I, a lifting handle II, a lifting heating column 10, a cavity 11, a through hole 12, a plug hole 13, a plug column 14, an upper die 15 and a shell 17.

Detailed Description

The technical solution proposed in the present patent will be described in further detail below with reference to the detailed description and the accompanying drawings.

Referring to fig. 1-4, a plastic mold with uniform heating function comprises a base 1, an upper mold 15 and a portable heating column 10, and is characterized in that: the base 1 is provided with a lower die 2, the lower die 2 is provided with a cavity 11, an annular heating device 4 is installed in the cavity 11, the outer wall of the lower die 2 is provided with a liquid filling port 6, the inner wall of the lower die 2 is provided with a scraping plate 5, the scraping plate 5 is provided with a through hole 12, and the top end of the lower die 2 is radially provided with two plug-in holes 16;

the portable heating column 10 comprises a first lifting handle 8, a counterweight 7, an electric heating rod 3, an insertion column 14 and a shell 17, wherein the counterweight 7 is installed in the shell 17, the electric heating rod 3 is arranged at the bottom of the shell 17, and the first lifting handle 8 is installed at the top of the shell 17; the center of the top of the upper die 15 is provided with a second handle 9, the electric heating rods 3 are uniformly distributed at the bottom of the shell 17, the electric heating rods 3 just can pass through the through holes 12, and the scraper plate 5 is movably connected with the lower die 2.

Principle of operation

When the heating device is used, the heat-conducting liquid is filled into the cavity 11 through the liquid filling port 6, the annular heating device 4 is started to heat, and the heating device is annular, so that the heat-conducting liquid can be uniformly heated, and the inner wall of the lower die can be uniformly heated; putting the raw materials into an inner cavity of a lower die 2, then inserting the plug-in post 14 of the portable heating post 10 into the plug-in hole 13, slowly lowering the portable heating post 10 downwards until the electric heating rod 3 contacts the raw materials, and switching on a power supply of the electric heating rod 3 to uniformly heat the raw materials in the horizontal direction; because the balancing weight 7 is arranged in the portable heating column 10, the self weight of the portable heating column 10 is larger, when the raw materials are gradually melted, the portable heating column 10 continuously moves downwards under the action of the self weight, and the raw materials are uniformly heated from top to bottom in the horizontal direction until the raw materials are completely molten; when the heating process is completed, the portable heating column 10 is slowly lifted upwards, the liquid plastic adhered to the electric heating rod 3 under the action of the scraping plate 5 is scraped and remained in the inner cavity of the lower die 2, then the scraping plate is taken out, the upper die 15 is put in from the top end of the lower die 2, and finally the required finished product is manufactured.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
