Abstract

PURPOSE:To obtain a mold for lead alloy where warpage is hardly generated and the temp. is easily adjusted and the crack is hardly generated by constituting the mold with ceramic having gas permeability to one side face of the mold and non-porous resin material to the other side face. CONSTITUTION:The one side face of the mold is composed of the ceramic 1 having gas permeability and the other side thereof is composed of the non- porous heat resistant resin 2. In the case of using polytetrafluoroethylene(PTFE) as the non-porous heat resistant resin material 2, since the PTFE has suitable elasticity in the combination of the ceramic and the PTFE, the PTFE is stuck to the ceramic material under good condition at the time of clamping the molds and the flashes are hardly generated. Further, since the temp. rising of the mold is little, the temp. adjustment is easily executed.

Conventional technology and its problems Traditionally, when making lead alloys, a so-called lubricant mainly composed of iron powder was sprayed onto the surface of a cast iron mold to provide functions such as correcting mold deformation, heat insulation, and mold release. I was allowed to have it. However,
This lubricant gradually deteriorates due to the heat of the molten lead, and its thickness decreases due to the pressing force of the lead alloy, making it impossible to produce good products over a long period of time. In the case of normal antimony alloys, the spraying needs to be corrected every 2,000 to 4,000 V II -/). In addition, it is extremely difficult to automate this process as partial repairs are sometimes sprayed during the process, called tufting. is necessary.

However, in the case of a mold made of breathable metal or ceramic materials, the mold temperature is rather high and warpage is likely to occur. Another drawback is that high precision is required for temperature control. In the latter case, there is a drawback that thermal stress is generated at the time of initial heating, causing cracking.

In the combination of ceramics and PTFE, since PTFE has appropriate elasticity, it adheres well to the ceramic material when the mold is closed and does not cause flaking. (Because no warping occurs.) Furthermore, as shown in Table 1, the temperature rise in the present invention is small, so temperature control is easy and no cracking occurs.
