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

Embodiment Construction
[0019] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.
[0020] see Figure 1-3 , a BMC injection mold plate surface deburring device, comprising a base 1, a drive motor 11, a left grinding device 16 and a right grinding device 17, the upper surface of the base 1 both sides are provided with shock absorbing columns 2, shock absorbing columns 2 A shock-absorbing spring is installed on the upper side of the shock-absorbing column 2. A platform 3 is provided on the upper side of the shock-absorbing column 2. A shock-absorbing spring sheet 4 is fixedly installed at the center of the lower side of the platform 3. The left and right parts of the lower side of the shock-absorbing spring sheet 4 are welded. There is a connecting piece 5, the lower side of the connecting piece 5 is welded with a slider 7, the surface of the base 1 has a chute 6, and the slider 7 is slidably installed inside the chute 6, between t...

The invention discloses a BMC injection mold plate surface deburring device which comprises a base, a driving motor, a left polishing device and a right polishing device. A polishing box is arranged on the upper surface of a platform; a driving device cavity is formed in the polishing box; a driving motor is fixedly mounted in the center of the upper side of the polishing box; the lower end of anoutput shaft of the driving motor is fixedly connected with a screw rod through a coupling; a sliding block is mounted on the screw rod in a threaded mode; connecting rods are fixedly welded to the two sides of the sliding block; and the other ends of the connecting rods located on the two sides penetrate through the driving device cavity and are fixedly connected with the left polishing device and the right polishing device correspondingly. The left polishing device and the right polishing device constantly move up and down, and thus the polishing effect is greatly improved; meanwhile, upperand lower molds of an injection mold can further be polished simultaneously, thus the polishing efficiency is greatly improved, and the time and labor are saved; and meanwhile, through the effect of squeezing springs, the polishing face of a polishing head makes contact with the mold surface all the time, so that the polishing effect is greatly improved.
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...
