Abstract

The utility model discloses a mould that removable anticorrosion was inserted, include the mould body and insert, be equipped with the runner on the mould body, insert and be located runner department, and can dismantle the cooperation with the runner, the surface of inserting is equipped with the pottery anticorrosive coating, and the pottery anticorrosive coating is used for preventing to insert the corruption, the utility model discloses rational in infrastructure, the pottery anticorrosive coating slows down the corruption of filtrating to inserting with the aluminium liquid contact of high temperature at first to increase the life who inserts, after being inserted and corroded completely, only need to change insert can, reduce the cost of changing, the life of extension mould.

Description

Mould of removable anticorrosion insert

Technical Field

The utility model relates to an aluminum alloy low pressure casting process field, in particular to mould that removable anticorrosion was inserted.

Background

The aluminum (magnesium, zinc) liquid is poured into the iron mold in a high temperature state, which corrodes the iron mold, and the gate attachment of the mold is most easily corroded due to the highest temperature of the aluminum (magnesium, zinc) liquid at the gate attachment, thereby making the entire mold unusable. The surface treatment of the entire mold increases the cost. In view of the above problems, a solution is proposed as follows.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a mould that removable anticorrosion was inserted has the position of inserting that corrodes the most seriously to the mould and carries out surface treatment, increases the corrosion resistance that inserts, and can only change the advantage of reduce cost to inserting after corroding.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides a mould of removable anticorrosion insert, includes the mould body and inserts, be equipped with the runner on the mould body, insert and be located runner department, and can dismantle the cooperation with the runner, the surface of inserting is equipped with the ceramic anticorrosive coating, the ceramic anticorrosive coating is used for preventing to insert the corruption.

Preferably, one side of the ceramic anticorrosive layer is provided with a tungsten alloy bonding layer, and the ceramic anticorrosive layer is connected with the insert through the tungsten alloy bonding layer.

Preferably, a positioning groove is formed in a pouring gate of the mold, a plurality of positioning blocks are arranged on the side wall of the insert block, and the positioning blocks are in inserting fit with the positioning grooves.

Preferably, the cross sections of the positioning block and the positioning groove are trapezoidal, and the positioning block is clamped in the positioning groove and matched with the positioning groove.

The utility model has the advantages that: the surface of the insert at the sprue of the die body is subjected to surface treatment, so that the corrosion resistance of the position, which is most easily corroded, of the die is increased, the insert can bear pouring for many times, the insert is not required to be frequently replaced, the working efficiency is increased, and when the insert is corroded and the die body is not corroded, the insert is only required to be replaced.

Detailed Description

The following is only the preferred embodiment of the present invention, the protection scope is not limited to this embodiment, and all technical solutions belonging to the idea of the present invention should belong to the protection scope of the present invention. In which like parts are designated by like reference numerals. It should be noted that as used in the following description, the terms "front," "back," "left," "right," "upper," and "lower" refer to directions in the drawings, and the terms "bottom" and "top," "inner," and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1, the die capable of replacing the corrosion prevention insert 2 comprises a die body 1 and the insert 2, wherein the die body 1 is provided with a sprue 3. The molten aluminum is poured into the mold body 1 from the gate 3, and the position which is firstly contacted with the molten aluminum is most easily corroded.

As shown in fig. 1, the insert 2 is located at the sprue 3 and is in first contact with the molten aluminum. Insert 2 and runner 3 and can dismantle the cooperation, the 3 departments of runner of mould are equipped with the constant head tank, are equipped with a plurality of locating pieces 6 on the lateral wall of 2 of inserting, and the cross-section of locating piece 6 and constant head tank all is trapezoidal, and locating piece 6 is pegged graft with the constant head tank and is cooperated. And taking the positioning block 6 out of the positioning groove, namely taking the insert 2 out of the sprue 3. When the insert 2 is corroded but the die body 1 is not corroded, the insert 2 only needs to be replaced, and the die can be used again, so that the cost is reduced.

As shown in fig. 2, a ceramic anticorrosive layer 4 is arranged on the surface of the insert 2, a tungsten alloy bonding layer 5 is arranged on one side of the ceramic anticorrosive layer 4, and the ceramic anticorrosive layer 4 is connected with the insert 2 through the tungsten alloy bonding layer 5. The ceramic anticorrosive layer 4 can enhance the corrosion resistance of the insert 2, so that the insert 2 can bear more times of filtrate erosion, the frequency of replacing the insert 2 is reduced, and the working efficiency of the casting mold is increased.

The working principle is as follows: insert the locating piece 6 of insert 2 and insert the constant head tank in, realize the installation of insert 2, only carry out surface treatment to the position that the mould body 1 is corroded most easily, set up ceramic anticorrosive coating 4 on insert 2, can reduce the input cost to the mould, and can increase the life of mould.

The above-mentioned embodiments further explain in detail the technical problems, technical solutions and advantages solved by the present invention, and it should be understood that the above only is a specific embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
