FIELD: chemical industry; devices and methods of filling of the molds for the compression molding of the plastic products.
SUBSTANCE: the invention is pertaining to the device and the method of filling of the molds for the compression molding of the plastic products. This invention ensures lowering of the values of the temperature and the pressure at the molding, more simple coupling of the molding device with the whole installation, the best heat insulation between the field of plastication and the field of cooling of the molds owing to filling the molds by feeding of the material "in the form of the drips". The device contains a set of the molding blocks for the compression molding. Each block contains the rod component of the mold and the molding cavity, which is filled in by feeding in it of the portion of the plastic material. Each of the molding blocks fulfils the molding sequence of operations including the operation of the mold opening, the operation of filling in the molding cavity and the operation of the mold shutting. The device contains tool of fixation and relocation of the positive component of the mold and-or the molding cavity beyond the limits of the vertical axes of the positive component of the mold between the operation of the mold opening and the operation of filling in the molding cavity.
EFFECT: the invention ensures reduction of the values of the temperature and the pressure at the molding, more simple coupling of the molding device with the whole installation, the best heat insulation between the field of plastication and the field of cooling of the molds.
