Manufacturing process for core box mould plastic sample core

Abstract

The invention discloses a manufacturing process for a core box mould plastic sample core. The manufacturing process comprises the following steps: (1), forming exhaust holes in an upper mould; (2), blocking off sand shooting holes; (3) lowering a lower mandrel; (4) sealing venting plug hole of a lower mould; (5) charging a mould releasing agent; (6) assembling the upper mould and the lower mould; (7) irrigating; (8) disassembling the upper mould and the lower mould; (9) cleaning and restoring the upper mould and the lower mould; and (10) clearing up the plastic sample core. According to the manufacturing process for the core box mould plastic sample core, a light plastic sample core can be manufactured so as to replace a sand core to perform core assembly verification of a sand type casting mould; the plastic sample core does not need to be manufactured in a production line, does not influence the regular production of the production line and can be used for reducing the manufacturing cost of the sand type casting mould.

Description

technical field [0001] The invention relates to the inspection field of sand casting moulds, in particular to a manufacturing process of a plastic sample core of a core box mould. Background technique [0002] After the sand casting mold is made, the mold verification work must be carried out, which is an important step in the mold making. Existing means: In addition to inspecting the size of each component and cavity of the mold, the mold must be sent to the production line or the production site to make sand cores, and then the cores are tested, the size of the cores is assembled, and the cores are assembled. A series of inspections such as checking the wall thickness of the parts by the mud strip, and returning to the mold factory for modification if problems are found in the inspection, and after the modification is completed, enter the previous second verification of sand core production. [0003] Although the existing mold verification methods can meet the production ...

AI Technical Summary

Problems solved by technology

[0004] 1. "Making sand cores on the production line or on the production site" uses the verification method of production line shutdown to make sand cores, which affects the normal production of the production line and virtually increases the manufacturing cost of sand casting molds

[0005] 2. The sand core of the diesel engine cylinder block is relatively heavy, and manual core assembly inspection is difficult, and the assistance of a crane is also required, and the operation is difficult and complicated

[0006] 3. The distance between the production line or the production site and the mold factory is long, and the cost of repeated logistics is high
