Embodiment 1

[0033] This embodiment discloses a method for coating and hanging lost foam, which includes the following steps:

[0034] Step 1. Bonding and combining multiple pieces of foam mold parts into a single casting, and reserving a first bonding surface glued to the ingate in the casting monomer, and pasting on the first bonding surface first tape;

[0035] Step 2: bonding the sprue, runner, and ingate to form a sprue assembly, and reserving a second bonding surface on the surface of the ingate to be bonded with the casting monomer, and A second adhesive tape is pasted on the second bonding surface;

[0036] Step 3, immerse and hang the casting monomer with the first tape pasted in step 1 and the runner assembly with the second tape pasted in step 2 respectively;

[0037] Step 4. Take out the casting monomer and sprue assembly after coating and hanging in step 3, and pour off the excess paint;

[0038] Step 5, drying the casting monomer and runner assembly in step 4;

[0039] Step...

Embodiment 2

[0049] like figure 1 , 2 As shown, this embodiment discloses a method for coating and hanging the lost foam of a three-cylinder body, including the following steps:

[0050] Step 1. Bonding and combining multiple pieces of foam mold parts into a single casting 1, and reserve a first bonding surface 11 glued to the ingate in the casting monomer, and place the first bonding surface 11 on the first bonding surface 11 Paste the first adhesive tape;

[0051] Step 2: bonding the sprue, runner, and ingate to form a sprue assembly, and reserving a second bonding surface on the surface of the ingate to be bonded with the casting monomer, and A second adhesive tape is pasted on the second bonding surface;

[0052] Step 3. Submerge and hang the casting monomer 1 with the first tape pasted in step 1 and the runner assembly with the second tape pasted in step 2 respectively, and the immersion time is 2 minutes;

[0053] Step 4. Take out the casting monomer 1 and the sprue assembly afte...

Abstract

The invention discloses a coating method of lost foam. The coating method includes the following steps that multiple foam mold parts are bonded and combined into a casting single body, and first adhesive tape is pasted on first bonding planes of the casting single body; second adhesive tape is pasted on second bonding planes of an inner runner; the casting single body and a runner assembly in thesecond step are subjected to immersion coating; the casting single body and the runner assembly which are subjected to coating are taken out and dried; the first adhesive tape and the second adhesivetape are torn down, the first bonding planes and the second bonding planes are glued, and assembly of the casting single body and the runner assembly is completed; supplementary paint brushing is conducted on non-bonded areas in the first bonding planes and the second bonding planes, and a product is obtained after drying. Compared with an existing coating method of the lost foam, the coating method has the beneficial effects of being low in labor cost, small in energy consumption and short in consumed time.

Description

technical field [0001] The invention relates to the technical field of lost foam, in particular to a method for coating and hanging the lost foam. Background technique [0002] More than 95% of the lost foam foundries in China mainly focus on controlling product quality in black areas. But it is often half the effort with half the effort and little effect. According to the statistics of foreign counterparts, more than 95% of the decision-making power for product quality lies in the white zone and the yellow zone. In the white zone and the yellow zone, the yellow zone accounts for 40% of the proportion. If the yellow area is being refined, the bonding process accounts for 10%, the coating and hanging process accounts for 45%, and the baking process accounts for 45%. Therefore, the coating and baking process is a very important process in the yellow zone. Here I mainly talk about the influence of painting and hanging technology. [0003] The white area refers to the produ...
