[Effects of the Invention] This invention allows several points of the pinpoint gate to be separated from the fixed side template and the movable side template when molding product parts such as seats for mechanical parts by resin outsert molding on a ceramic substrate. At the same time, a tab is provided on the movable side mold plate at this position, and a submarine gate is connected to this tab to flow the resin to the product part to be molded on the five sides of the ceramic substrate. Because of this, the press-fitted resin applies equal injection pressure and holding pressure vertically to the upper and lower surfaces of the ceramic substrate. Therefore, the ceramic substrate does not break or crack as in the prior art.

Also, when molding the product parts on the upper and lower surfaces of the ceramic substrate and trying to release the mold, residual particles may remain on the runner gate and bin point parts on the fixed side, as well as the tab parts and submarine gate parts on the movable side. Since the cured resin can be easily peeled off and removed separately from each product part, this invention has various effects such as improved workability.

It consists of a fixed side template and a movable side template, and the fixed side template has a resin press-fitting part and a runner gate part, and
Pinpoint gates are provided at various places in the runner gate portion, and a ceramic substrate is inserted into the movable mold plate, and both mold plates are joined to perform outsert molding. Then, several points of the pinpoint gates are installed at the mold dividing plane between the fixed side mold plate and the movable side mold plate, and a rectangular parallelepiped shape with ejector pins arranged below is placed on the movable side mold plate at the position. Along with providing a tab,
An outsert molding device for a ceramic substrate, characterized in that a submarine gate is connected to the tab so that resin can flow from the submarine gate to a product molding section on the movable side.
