Description
Technical Field
The utility model discloses be applied to the technical field of mould, in particular to double oil cylinder mould.
Background
An injection mold is a tool for producing plastic products; and is also a tool for giving the plastic product complete structure and accurate dimension. Injection molding is a process used to mass produce parts of some complex shapes. Specifically, the plastic melted by heating is injected into a mold cavity from an injection molding machine at high pressure, and a formed product is obtained after cooling and solidification. To by the internal thread injection molding, traditional injection mold adopts the single cylinder to drive movable mould board and quiet template cooperation and forms the chamber of moulding plastics, and the internal thread shaping piece then sets up in the intracavity portion of moulding plastics, and then accomplishes the shaping of internal thread, however this kind of processing method very inconvenient when getting the piece, damage inner structure easily when getting the piece simultaneously.

The utility model adopts the technical proposal that: the utility model discloses a last mould and bed die of mutually supporting, the bed die includes bottom plate, template, oil cylinder subassembly and tapping subassembly, the template is embedded on the bottom plate, two pneumatic cylinders that the oil cylinder subassembly set up including the symmetry, two the pneumatic cylinder all with bottom plate fixed coordination, two the expansion end of pneumatic cylinder all is provided with the compound die block, be equipped with first shaping groove on the compound die block, two first shaping groove cooperatees and forms first chamber of moulding plastics, the tapping subassembly includes screw thread post and actuating mechanism, be equipped with on the bottom plate with the screw hole of screw thread post looks adaptation, actuating mechanism drives the screw thread post is rotatory, the screw hole is located under the first chamber of moulding plastics.
According to the scheme, the two mold clamping modules driven by the hydraulic cylinder to operate are matched to form the first injection molding cavity, so that the injection molding part is prevented from being clamped due to matching of the mold plate and the tapping assembly, and the injection molding part is taken out more easily. The traditional mode of getting is taken out the injection molding by the manual work from the rotation of fixed internal thread formed part, through adopting rotatable formula screw thread post as internal thread formed part, and through actuating mechanism drives the screw thread post rotates, and then realizes screw thread post autogiration breaks away from with the injection molding, and then reduces artifical intensity of labour, effectively improves production efficiency.
According to a preferable scheme, the template is provided with a plurality of butt-joint blocks, and the upper die is provided with butt-joint grooves matched with the butt-joint blocks.
According to the scheme, the butt joint blocks and the butt joint grooves are matched, so that the upper die and the lower die are matched more accurately, and the molding effect of the injection molding piece is improved.
The mold plate and the upper mold are respectively provided with a second molding groove, the second molding grooves are matched to form a second injection molding cavity, and the second injection molding cavity is communicated with the first injection molding cavity.
By the scheme, the second molding grooves are matched to form the second injection molding cavity, injection molding of injection molding parts without internal thread requirements is achieved, meanwhile, the second injection molding cavity is communicated with the first injection molding cavity, injection molding of the second injection molding cavity and the first injection molding cavity is achieved, and production efficiency is effectively improved.
One preferred scheme is that the driving mechanism comprises a driving motor, a chain wheel and a chain, the chain wheel is fixed on the threaded column, and the driving motor is in transmission fit with the chain wheel through the chain.
According to the scheme, the threaded column is driven to rotate by adopting chain transmission.
According to a preferable scheme, a plurality of guide posts are arranged on the bottom plate, and guide grooves which are matched with the guide posts in a one-to-one correspondence mode are formed in the upper die.
According to the scheme, the guide columns and the corresponding matched guide grooves are arranged, so that the upper die and the lower die are matched more accurately, and the molding effect of the injection molding part is improved.
