A deburring device for the surface of a bmc injection mold plate

Abstract

The invention discloses a BMC injection mold plate surface deburring device, which includes a base, a drive motor, a left grinding device and a right grinding device, a grinding box is provided on the upper surface of the platform, and a driving device cavity is provided inside the grinding box. The center position of the upper side of the grinding box is fixedly installed with a drive motor, and the lower end of the output shaft of the drive motor is fixedly connected with a screw rod through a coupling. A slider is threaded on the screw rod, and connecting rods are fixedly welded on both sides of the slider. The other ends of the connecting rods on both sides pass through the drive device cavity and are respectively fixedly connected with a left grinding device and a right grinding device. Through the continuous up and down movement of the left grinding device and the right grinding device, the grinding effect is greatly improved. At the same time, the upper and lower molds of the injection mold can be polished at the same time, thereby greatly improving the grinding efficiency and saving time and effort. At the same time, through extrusion The effect of the spring, so that the grinding surface of the grinding head is always in contact with the surface of the mold, thereby greatly improving the grinding effect.

Description

technical field [0001] The invention relates to the field of molds, in particular to a device for deburring the surface of a BMC injection mold plate. Background technique [0002] BMC is a molded intermediate material for glass fiber reinforced thermosetting products produced by a semi-dry method. It is pre-mixed into a paste from unsaturated polyester resin, low shrinkage / low profile additives, initiators, internal mold release agents, and mineral fillers. Thickeners, colorants, etc. are added, and glass fibers of different lengths are stirred in a special material kettle to carry out the thickening process, and finally form a doughy intermediate material, which can be used for molding and injection molding. [0003] When plastic-sealed motors are injected, the mold of the injection mold needs to be deburred frequently, so as to prevent the surface of the plastic-sealed motor from having pores and other poor appearance after injection molding. The existing mold grinding de...

Problems solved by technology

[0003] When plastic-sealed motors are injected, the mold of the injection mold needs to be deburred frequently, so as to prevent the surface of the plastic-sealed motor from having pores and other poor appearance after injection molding. The existing mold grinding device cannot be used for grinding. The upper and lower molds of the mold are polished at the same time, the grinding efficiency is low, and the position cannot be adjusted during grinding, resulting in poor grinding effect
