Description
Technical Field
The utility model relates to an injection mold, especially an exempt from to push up injection mold.
Background
With the social development, the application of plastic products is very wide, and most of the plastic products are produced by an injection molding process. The common injection molding method comprises the following steps: the plastic raw material in a molten state is injected into a metal mold for molding, the metal mold is generally composed of a front mold and a rear mold, the front mold and the rear mold are separated after molding, then an ejector plate in the rear mold is driven by a power driving unit to move, and a molded product is ejected out of a molding cavity in the mold through an ejector pin on the ejector plate.
However, some products have high requirements on appearance, require a very smooth surface, and cannot have scratches, roughness and the like on the surface, so that the mode of ejecting the product by directly contacting the ejector pin with the product cannot meet the requirements, and the applicant designs a top-free injection mold to solve the problems.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides an injection mold free of top.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a top injection mould exempts from, includes front mould, back mould, be equipped with preceding die cavity in the front mould, be equipped with back die cavity, its characterized in that in the back mould: the rear die is provided with a forming table, a forming block, a sliding plate, a top plate hole and a top plate located in the top plate hole, the top plate is provided with a top post, the top post penetrates through a sliding hole formed in the inner wall of the top plate hole to be fixed with the sliding plate, the sliding plate is provided with a plate sliding groove, the forming block is provided with an oblique guide hole and a sliding block matched with the plate sliding groove, the sliding block is located in the plate sliding groove, a rear cavity is enclosed by the forming table and the forming block, an oblique guide pillar is arranged in the rear die, the bottom surface of the plate sliding groove is provided with a avoiding hole, the oblique guide pillar penetrates through the avoiding hole to be matched with the oblique guide hole, the sliding plate slides through a sliding shaft fixed on the rear die, the sliding plate is provided.
The rear mold comprises a first plate, a second plate and two side plates, the top plate hole is defined by the first plate, the second plate and the two side plates, and the forming table is located on the second plate.
The inner walls of the two sides of the plate sliding groove are provided with inner sliding grooves, and the sliding block is provided with sliding strips matched with the inner sliding grooves.
The plate sliding groove is characterized in that an inner boss is oppositely arranged at the groove bottom of the plate sliding groove, a limiting block fixed through a screw is arranged on the inner boss, and the inner sliding groove is formed by the inner boss, the limiting block and the groove bottom of the plate sliding groove in a surrounding mode.
And the sliding plate is provided with an ejector plate limiting column.
The utility model has the advantages that: the mould of this structure adopts the slide structure, and then the fore-set on the thimble board is not direct contact work piece but the jack-up slide, drives the shaping piece through the slide and ejecting the work piece from the shaping platform, then the shaping piece is separated with the shaping platform through the drive of oblique guide pillar when rising to make the work piece deviate from, above-mentioned structure has avoided the direct roof pressure work piece of thimble (because the strength is big when the thimble roof pressure work piece, forms mar, coarse at the work piece easily), thereby has guaranteed the smooth finish on work piece surface.
