Forming method of heat sealing mold

Abstract

The invention belongs to the field of heat exchanger forming, and particularly relates to a heat seal die forming method. A heat seal die comprises an upper die body, a lower die body and a guide column facilitating matching of the upper die body and the lower die body. The heat seal die forming method comprises the following steps that A, a plastic framework is placed on the lower die body and positioned; B, the plastic framework is covered with an aluminum foil; C, the upper die body is heated to be at the temperature ranging from 210 DEG C to 220 DEG C; D, an air cylinder is used for driving the upper die body to extrude the lower die body, pressure is controlled to range from 0.9 MPa to 1.1 MPa, and the die assembly time does not exceed 3s; E, the temperature of the contact face of the upper die body and the aluminum foil is reduced to range from 110 DEG C to 130 DEG C, and the cooling time does not exceed 1s; and F, the air cylinder drives the upper die body to move upwards for die striping, and a formed heat seal piece is obtained. The heat seal die forming method adopting the technical scheme is high in bonding efficiency, and rapid drying can be achieved.

Description

technical field [0001] The invention belongs to the field of forming heat exchangers, and in particular relates to a forming method of a heat-sealing mold. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, and is often used as a heater, cooler, condenser, evaporator and reboiler. Heat exchangers are common equipment in chemical industry, petroleum, power, food and many other industrial sectors, and play an important role in production. The main part of the heat exchanger is the heat exchange fin. Multiple heat exchange fins of the same specification are stacked together. There are staggered fluid flow channels on the heat exchange fins. The cold fluid and the hot fluid pass through the adjacent flow channels respectively, and the hot fluid transfers the heat Transfer to cold fluid to realize heat exchange. [0003] In existing heat exchangers, the fluid passages in the heat exchange fins usually need ...

Problems solved by technology

However, there is no special process for bonding at present, and manual operation is required, which has disadvantages such as low efficiency, unguaranteed bonding quality, unstable glue quality, and the drying process is limited by ambient temperature and humidity.
