Embodiment Construction

[0020] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] In order to solve the problem in the prior art that it is difficult to measure the thickness of a closed mold cavity, the invention provides a method for measuring the thickness of a mold cavity.

[0022] like figure 1 As shown, the cavity thickness measurement method includes steps S1 to S5, wherein, step S1: place the test material in the lower sand box 10; step S2: fasten the upper sand box 20 on the lower sand box 10, so that the test material is Extrude and extend in the mold cavity 30; Step S3: Remove the upper sand box 20; Step S4: Take out the test material from the lower sand box 10; Step S5: Measure the thickness of the test material, which is equal to the thickness of the mol...

Abstract

The invention provides a measuring method for thickness of a cavity. The measuring method comprises the following steps: S1, putting a testing material in a drag flask; S2, buckling a cope flask onto the drag flask so as to enable the testing material to be extruded and extend in the cavity; S3, removing the cope flask; S4, taking out the testing material from the drag flask; S5, measuring the thickness of the testing material, wherein the thickness of the testing material is equal to that of the cavity. As the testing material is put in the cavity, and the testing material is adapted to the surface of the cavity and extends in the cavity through pressure, by measuring the thickness of the deformed testing material, the thickness of the cavity can be directly obtained; therefore, the thickness of the cavity has the characteristic of being easy to measure; further, the inner wall of the cavity can be repaired according to the thickness of the cavity, so the wall thickness of a casting product is ensured.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a method for measuring the thickness of a mold cavity. Background technique [0002] With the development of casting technology, the wall thickness of castings is getting thinner and thinner. The casting process needs to use measuring tools to measure and control the thickness of the cavity. [0003] In the prior art, the thickness of the cavity is generally measured by the method of plugging the ball. Because some cavities are closed cavities, the plug ball method cannot be used for measurement, so it is difficult to guarantee the thickness of the cavity and the wall thickness of the product. Contents of the invention [0004] The main purpose of the present invention is to provide a method for measuring the thickness of a mold cavity to solve the problem in the prior art that it is difficult to measure the thickness of a closed mold cavity. [0005] In order to achieve the ...
