Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mold production, in particular to a tunnel type mold production line. BACKGROUND

[0002] The mold refers to using the original sample to make a silica gel mold in a vacuum state, and after pouring into the silica gel mold, the same replica as the original sample is obtained.

[0003] In the process of mold production and processing, the mold filled with silica gel needs to be sent into a tunnel furnace for baking and curing. The curing time is generally about one and a half hours (the specific time is determined according to the actual situation), and the tunnel furnace is a heating furnace with a long furnace channel. The tunnel furnace for curing silica gel generally uses electric heating to control the temperature between 100° and 200°. Therefore, evenly distributed heating wires need to be arranged on the upper and lower four sides of the furnace channel, so that the entire furnace channel is in a high temperature environment. The mold with silica gel needs to be sent into the furnace channel through a transmission belt. At this time, the furnace door of the tunnel furnace is closed. After baking and curing, the mold is transported out through the transmission belt for the next step of taking out the mold.

[0004] In this process, a large number of molds need to be distributed in the furnace channel, so that the length of the furnace channel is long, the width is wide, and the space for the movement of the transmission belt needs to be provided, so that the height of the furnace channel is high. This promotes the overall space of the furnace channel to be large, and more heating wires need to be laid in a large area to meet the heating of the entire furnace channel. That is, more power needs to be consumed, and a large amount of heat is dispersed in the entire furnace channel. Part of the heat is absorbed by the internal structures such as the inner wall of the tunnel furnace and the transmission belt, so that the effective heating of the mold is reduced, resulting in poor heating effect of the mold. SUMMARY

[0005] The present application provides a tunnel type mold production line, which has the advantages that a small space is formed in the curing box, heat is concentrated in the curing box to efficiently heat the mold, the thermal expansion of the gas in the curing box is matched with the evaporation of the mold to increase the pressure in the curing box, the heat absorption of the liquid storage pipe causes the internal liquid to evaporate into gas and enter the pressurizing cavity, the increased pressure of the pressurizing cavity pushes the movable plate to press the heating cavity for secondary pressurization, and the airflow in the pressurizing cavity improves the heat transfer effect, so as to solve the problems of large invalid heating space, high power consumption and low heating efficiency in the existing tunnel furnace.
