specific Embodiment approach 1

[0011] Specific implementation mode one: combine figure 1 , the present embodiment is an instant mold core that shortens the removal time, and it is composed of a cavity mold core 1 and a support rod 2; the support rod 2 is composed of a rod body 2-1, a reference surface 2-2 and an external thread; the The top of the support rod 2 is processed into an external thread, and the inner cavity of the cavity mold core 1 is processed into an internal thread, so that the cavity mold core 1 and the support rod 2 are screwed together; the rod body 2-1 of the support rod 2 A reference surface 2-2 is processed between the outer thread and the external thread, ensuring that the diameter of the reference surface 2-2 is equal to the outer diameter of the cavity mold core 1.

[0012] The support rod 2 described in this embodiment is cylindrical, and the top end of the support rod 2 has an external thread. Compared with the external thread, it can play a stable clamping role in the preparatio...

specific Embodiment approach 2

[0013] Specific implementation mode two: combination figure 1 The difference between this embodiment and the first embodiment is that a contact gap 3 is provided between the cavity core 1 and the reference surface 2-2, and the width of the contact gap 3 is 50 μm˜100 μm. Others are the same as the first embodiment.

specific Embodiment approach 3

[0014] Specific implementation mode three: combination figure 1 The difference between this embodiment and the specific embodiment 1 or 2 is: there is a gap 4 between the top of the cavity core 1 and the top of the external thread of the support rod, and the width of the gap 4 is 50 μm to 100 μm . Others are the same as those in Embodiment 1 or 2.

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 2 and 3 The purpose of setting the contact gap 3 and the gap 4 is to facilitate the removal of the cavity mold core 1 from the support rod 2 .

Abstract

The invention relates to a mold core and a using method thereof, in particular to a quick dissolving mold core capable of shortening removal time and a using method thereof. By means of the quick dissolving mold core capable of shortening the removal time and the using method thereof, the problems that the removal time of an existing aluminum mold core is long, consequently, the possibility that a uranium layer of an NIF block cavity is corroded and destroyed is increased, and the failure rate caused by demolding in the preparation process of the NIF block cavity is high are solved. The quick dissolving mold core capable of shortening the removal time is composed of a cavity mold core body and a supporting rod. The supporting rod is composed of a rod body, a reference plane and an outer thread. The using method includes the steps that 1, coating is carried out, so that the cavity mold core body coated with the uranium-containing black cavity coating is obtained; and 2, demolding is carried out, and accordingly the uranium-containing black cavity is obtained. The quick dissolving mold core capable of shortening the removal time and the using method thereof have the advantages that the removal time is greatly shortened, post processing and fracture protection layer plating procedures are omitted, and production efficiency is improved. The quick dissolving mold core is mainly provided and utilized for preparing the uranium-containing black cavity.

Description

technical field [0001] The invention relates to a mold core and a method for using the same. Background technique [0002] The U-containing black cavity has a high energy gain, which can reduce the ignition energy requirement of the driver, increase the ignition energy margin, and reduce the ablation of the optical device. It is selected by the NIF ignition freezing target experiment. However, the chemical properties of U are extremely active, and after oxidation, the ionization heat capacity of the black cavity wall will be increased, resulting in a significant decrease in its conversion efficiency. Traditional aluminum or copper mandrels are no longer suitable. In order to reduce the possibility of oxidation or hydrogen embrittlement of the uranium layer, and reduce the probability of over-corrosion of the black cavity, the American NIF uranium-containing ignition black cavity development process uses an aluminum-copper composite mandrel (that is, the aluminum mold core i...
