Embodiment 1

[0027] Embodiment 1, as attached figure 1 , figure 2 , image 3 and Figure 4 Shown:

[0028] The special device for mold preheating includes a base 1, the base 1 is vertically provided with a lifting mechanism, the upper end of the lifting mechanism is movably connected to a moving rod 2, a heating jacket is slidably connected to the moving rod 2, and a power supply 3 is connected to the heating jacket; The lifting mechanism includes a motor 4, the output shaft of the motor 4 is connected with a worm 5, the worm 5 is engaged with a worm wheel 6, and the center hole of the worm wheel 6 is engaged with a vertical screw 7, and the upper end of the screw 7 is fixedly connected to one end of the moving rod 2, The worm wheel 6 and the worm 5 joint are provided with a baffle 8 to prevent the axial movement of the worm wheel 6; the heating jacket includes two layers of arc-shaped heating nets 9 arranged up and down, and the heating net 9 is fixed with an insulating layer 10, and ...

Embodiment 2

[0035] Embodiment 2, as attached Figure 5 Shown:

[0036] The difference from Embodiment 1 is that the heating grid 9 is formed by criss-crossing linear heating wires, which facilitates the installation and manufacture of heating wires, and facilitates the replacement and maintenance of a single heating wire. The insulation layer 10 is a high temperature resistant fiber layer structure, simple in structure, and easy to install and replace.

Description

technical field [0001] The invention relates to the field of mold auxiliary equipment, in particular, the design relates to a special device for mold preheating. Background technique [0002] In the daily glass blowing process, molds are mostly used for shaping. Before the mold is used, it needs to be preheated, because if the surface of the mold is not preheated, the contact surface between the high-temperature glass solution and the mold will shrink sharply in size, and the temperature of the core of the glass blowing part will drop evenly, resulting in the glass blowing. The surface of the part will be pulled apart, forming cracks. In addition, the temperature of the glass solution in contact with the cold mold will drop rapidly, resulting in uneven temperature inside and outside the molded product, and the shape of the glass blow molded part is not round and regular, that is, the degree of shrinkage of the mold and the glass blow molded part is different. [0003] In t...
