A kind of preparation technology of epoxy resin mastic mold

Abstract

The invention discloses a preparation process of an epoxy resin cement mold, which belongs to the technical field of mold forming. The method includes the following steps: (1) setting a detachable adhesive paper on the inner wall of the mold cavity; (2) laying cured and formed epoxy resin bricks in the mold cavity, and filling epoxy resin between adjacent epoxy resin bricks The cement is filled with epoxy resin cement in the gap between the epoxy resin brick and the mold cavity inner wall, so that a plurality of epoxy resin bricks are connected into a whole by the epoxy resin cement; (3) the ring in the step (2) After the epoxy resin mastic is cured, an epoxy resin mastic mold is formed as a whole. The present invention adopts the prefabricated cured and formed epoxy resin bricks to be bonded by the prepared epoxy resin cement to form an integral epoxy resin cement mold, which is convenient for molding and construction, saves curing time and improves production efficiency.

Description

technical field [0001] The invention belongs to the technical field of mold forming, and in particular relates to a preparation process of an epoxy resin cement mold. Background technique [0002] The laying process of existing mold matrix cement generally adopts the mode that the mixer and the good cement are directly manually laid. The manual laying method has the following technical problems: [0003] 1. Now artificially laid cement is more suitable for small-batch production mode when orders are not busy. If it is produced in large quantities: the production method of ready-made cement and ready-to-pave mud is very compact, and manual production cannot meet the production process progress. Or, when manually laying large mold cavities, it often happens that the dough mixer does not supply cement in time. The main reason is that there is a connection problem in the dough-filling process, which will seriously cause the interruption of the process rhythm and the idleness of...

AI Technical Summary

Problems solved by technology

[0003] 1. Now artificially laid cement is more suitable for small-batch production mode when orders are not busy. If it is produced in large quantities: the production method of ready-made cement and ready-to-pave mud is very compact, and manual labor cannot meet the production process progress

Or, when manually laying large mold cavities, it often happens that the dough mixer does not supply cement in time. The main reason is that there is a connection problem in the dough-filling process, which will seriously cause the interruption of the process rhythm and the idleness of the workers.

[0004] 2. Manual laying of cement, because the softness and hardness of the cement are different, it is easy to have false laying and large voids during the laying process, and tiny cracks are prone to appear in the mold matrix resin; at the same time, during the construction process of laying the cement, due to manual operation Improper filling, uneven filling, excessive twisting, rubbing, kneading and other violent actions will easily add "thermal internal stress" to the uncured rubber itself, resulting in the inability to release the stress of the mold matrix resin, and the stress will increase, resulting in deformation, etc. , resulting in the final stress concentration of the mold product, prone to cracking

[0006] 4. The cement itself after mixing is relatively viscous and brittle

It is more laborious to construct, and it does not use to fill the gaps

And after the cement is stirred, the number of times of handling is too much, because of the stickiness, too much sticks to the inner wall of the mixing equipment and the mixing blades, making it difficult to clean
