Embodiment 1

[0027] Embodiment 1, as attached figure 1 , figure 2 , image 3 with 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 with a moving rod 2, the moving rod 2 is slidably connected with a heating jacket, and the heating jacket is connected with a power supply 3; The lifting mechanism includes a motor 4, the output shaft of the motor 4 is connected with a worm 5, the worm 5 is meshed with a worm wheel 6, the center hole of the worm wheel 6 is meshed 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 that prevents 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, ...

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.

Abstract

The patent relates to the field of auxiliary equipment of molds, and discloses a special device for preheating a mold. The device comprises a base seat, wherein a lifting mechanism is vertically arranged on the base seat; a movable rod is connected to the upper end of the lifting mechanism in a movable manner; a heating sleeve is connected to the movable rod in a sliding manner; a power supply isconnected to the heating sleeve; the lifting mechanism comprises a motor; worms are connected to an output shaft of the motor; the worms mesh with a worm wheel; the worm wheel vertically meshes with alead screw at a central hole; the upper end of the lead screw is fixedly connected with one end of the movable rod; a baffle plate for preventing the worm wheel from moving axially is arranged at a joint of the worm wheel and the worm; the heating sleeve comprises two layers of arc-shaped heating nets which are arranged up and down; heat preservation layers are fixedly arranged on the heating nets; the same sliding sleeve is connected to one end of each of the two layers of the heating nets in a hinged manner; and the sliding sleeve is connected with the movable rod in a sleeved manner. Thispatent is intended to provide the special device for preheating the mold with simple structure and heat preservation effect.

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...
