Abstract

The invention provides a quick normal temperature pouring device based on an SLA photocuring technique and a method thereof and relates to the technical field of die manufacturing. The pouring devicecomprises an SLA photocuring forming module, an ultrasonic cleaning module, an injection molding module and a high-temperature oil fluid melting module. The method comprises the following steps of designing an inclusive molding cavity according to a part model; quickly printing and manufacturing the cavity by employing the SLA photocuring technique; pouring a liquid material by using a needle syringe and leaving the liquid material to stand; and flushing the liquid material by a high-temperature oil fluid to achieve a demolding process according to a melting point difference between the cavitymaterial and the pouring material. The device simplifies the manufacturing process of the pouring die, changes the problems of long consumed time and high cost when low-temperature pouring material parts such as epoxy resin are manufactured in a small batch and is of significant meaning in quick pouring and forming of thin-walled parts with depth-diameter ratios.

Description

technical field [0001] The invention relates to a rapid room temperature casting equipment and method based on SLA photocuring technology, and relates to the technical field of mold manufacturing. Background technique [0002] In the molding process of product components in the modern manufacturing industry, the casting mold manufacturing method is widely used. Among them, the room temperature casting mold is a process of duplicating and molding plastic products through a specific shape, and it is an efficient way to process plastic products. [0003] SLA light-curing technology is to use specific wavelength and intensity laser to focus on the surface of the light-curing material, so that it is solidified sequentially from point to line, from line to surface, and completes a layer of drawing work, and then the lifting platform moves a layer in the vertical direction Height, and then solidify another layer, layer upon layer to form a three-dimensional entity. The technology...
