Embodiment 1

[0018] The manufacture method of the wooden mold core box of the present embodiment may further comprise the steps:

[0019] A. Raw material processing: make wood into several wood laminates of specified size, then clean the wood laminates and put them into a microwave drying kiln for low-temperature drying and sterilization, and then soak the wood laminates in a bonding agent with a concentration of 20%. solution, the soaking time is 10 minutes, and then put the wood laminate into a microwave drying kiln for drying. After drying, the moisture content of the wood laminate is not higher than 10%;

[0020] B. Antiseptic treatment: soak the wood laminate obtained in step A in a 25% preservative solution for 20 minutes, and then put the wood laminate into a microwave drying kiln for drying. After drying, the wood layer The moisture content of the board is not higher than 10%;

[0021] C. Splicing and forming: Prefabricate the casting channel with the wood laminates obtained in st...

Abstract

The invention discloses a manufacturing method of a wooden mold core box, and relates to the technical field of mold manufacturing. The manufacturing method of the wooden mold core box comprises the following steps that A, raw material treatment is conducted; B, preservative treatment is conducted; C, splicing molding is conducted; and D, fixed finishing is conducted. In the step D, connecting pieces used for fixing are wooden nails, the outer surfaces of the wooden nails are sleeved with wooden nail sleeves with the sizes being 1.1-1.3 times that of the wooden nails, and the wooden nail sleeves are made of resin or rubber. According to the wooden mold core box manufactured through the manufacturing method, compared with the prior art, the surface hardness of the wooden mold core box can be improved, the water content is low, deformation damage is not easy to occur, the probability of being affected by changing of the temperature and the humidity is greatly reduced, corrosion is not easy to occur, the service life of the wooden mold core box is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a method for manufacturing a wooden mold core box. Background technique [0002] Wooden mold is a common non-metal mold; wooden core box is a mold specially used to manufacture cores. It often adopts a split structure of upper box and lower box. When manufacturing sand cores, the upper box and lower box are combined. , and then inject liquid resin or liquid metal into the cavity of the core box from the casting channel to make the core; because in the manufacturing process, the upper box and the lower box must be tightly combined and fully cast to produce sand with sufficient hardness Core; wooden mold core boxes often use wood for multi-layer splicing into a box body, and then create a curved surface in the middle of the box body, and use bendable wood to splice and fix the curved surface to form a cylindrical cavity in the box body for casting Liquid metal; however,...
