A kind of glass-ceramic preparation mold that can be quickly demolded

Abstract

The invention relates to the technical field of molds, in particular to a glass-ceramic preparation mold that can be quickly demolded. The specific technical scheme is as follows: a glass ceramic preparation mold that can be quickly demolded, comprising a bottom plate, a slide rail with a slider is arranged in parallel on the bottom plate, and a slide rail with a slider is arranged on the bottom plate and located between the two slide rails. For the supporting plate that moves up and down, the sliders of the two slide rails are provided with fixed seats. When the fixed seats are located above the supporting plates, the supporting plates are abutted against the fixed seats, and a split mode is arranged in the fixed seats. A split-type mold cover is arranged in the fixed seat and above the split-type mold core, and a plurality of casting holes are arranged on the split-type mold cover. The mold disclosed in the present invention realizes rapid demoulding through rapid changeover in different stations.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a glass-ceramic preparation mold that can be quickly demolded. Background technique [0002] The casting molding of glass ceramics is similar to the traditional metal casting. The raw materials are heated and melted to a liquid state, and then the liquid raw materials are poured into the mold of the desired shape, and when the liquid raw materials are cooled to a solid or semi-solid state, they are removed from the liquid state. It is released from the mold and the product of the specific shape required is obtained. [0003] In order to obtain glass ceramics of a specific shape and facilitate the demoulding of products after casting, the traditional glass ceramic casting molds are generally split, such as figure 1 As shown, it includes a base plate 1a, a fixed base 1b symmetrically arranged on the base plate 1a, a mold core 1c disposed in the area enclosed by the two fixed bases 1...

AI Technical Summary

Problems solved by technology

[0004] However, the traditional casting mold has the following defects: ① There are no fasteners in the mold structure. When the hot-melt glass ceramics is poured, due to the flow force of the liquid and the physical characteristics of thermal expansion and contraction, the original assembled parts will be slightly deformed. Movement will eventually lead to poor product molding quality and low yield; ②Due to the fluidity of hot-melt raw materials, in order to prevent the poured raw materials from flowing out of the mold, the mold cover is designed with a depression, and the raw materials must be ejected during pouring hole, so that when it is cooled to a semi-solid state, the excess raw material on the upper surface of the pouring hole will solidify into one, and the effect of rapid demoulding of the product cannot be achieved. In the later stage, only tools can be used to smash the excess raw material on the upper layer of the pouring hole before the product can be removed. Demoulding; ③ Due to the long-term pouring of hot-melt raw materials, the mold will have a certain deformation after a period of use, which will lead to poor combination of molds with good tolerances before, and eventually lead to unqualified products; ④ Efficiency Low, requiring precise and careful operation of workers, high labor intensity
