In order to achieve the technical effect, the invention provides a foaming mold with clearance compensation, which comprises a base, a locking mechanism, a cover plate, a compression plate, an exhaust device, a material blocking mechanism and a box body, wherein the box body is arranged on the base, the lower surface of the cover plate is provided with an annular groove, the compression plate is arranged in the annular groove of the cover plate, the cover plate covers the box body, the cover plate and the base are locked by the locking mechanism, the center of the cover plate is provided with a pouring gate and the material blocking mechanism, the exhaust device is arranged on two sides of the material blocking mechanism, and the cover plate is also provided with a hanging ring for dismounting the cover plate.
Furthermore, a plurality of shallow grooves are uniformly arranged in the ring groove of the cover plate.
Further, the material of the compression plate is plastic.
Further, the compression plate is arranged in the annular groove of the cover plate in an interference fit mode.
Furthermore, the number of the exhaust devices is two, and the exhaust devices are symmetrically arranged on two sides of the material plugging mechanism.
Furthermore, the number of the lifting rings is two, and the two lifting rings are symmetrically arranged on the outer side of the exhaust mechanism.
Furthermore, 8 locking mechanisms are arranged, and the locking mechanisms are uniformly arranged around the cover plate and around the bottom plate and used for locking the cover plate and the bottom plate.
Furthermore, a supporting component is arranged above the material blocking mechanism.
The present invention is further explained and illustrated below, and the mold is mainly composed of a base, a locking mechanism, a lifting ring, a cover plate, a compression plate, an exhaust device, a material blocking mechanism, a support component and a box body. During assembly, the box body is placed on the base, the upper cover plate is placed, plastic is directly added into a cavity inside the device through a pouring gate of the cover plate through the locking device of the locking mechanism, the material blocking mechanism is compressed through the supporting component to foam, and the air exhausting device is blocked after the plastic is foamed for a certain time. After foaming is finished, the locking mechanism is loosened, the cover plate and the compression plate are detached through the hanging ring, and the box body foaming forming part is taken out. The lower surface of the cover plate is provided with a ring groove, a plurality of shallow grooves are processed in the ring groove, and when the compression plate is used, the compression plate is arranged in the ring groove of the cover plate. The compression plate can generate proper deformation due to compression and is embedded into the shallow groove in the cover plate ring groove, the M surface and the N surface of the cover plate and the box body are ensured to be contacted simultaneously, the fit clearance between the cover plate and the box body is reduced, the foam is prevented from overflowing the anodized surface of the box body through the M surface clearance, and the anodized film layer falling phenomenon of the box body is solved.
The invention has the following beneficial effects: the cover plate of the die is provided with the ring groove, and the ring groove is internally provided with the plurality of shallow grooves, so that when the die is used, the compression plate can self-adaptively compensate the fit clearance between the cover plate and the contact surface of the box body by means of pressure. Through reducing the fit clearance between apron and the box, the foam spills over the box anodization surface when effectively avoiding foaming.
