Abstract

The invention discloses a tray mold facilitating injection molding of bottom feet. According to the technical scheme, the tray mold is characterized in that the tray mold comprises a fixed mold body and a movable mold body; the fixed mold body is provided with a plurality of protrusions for injection molding of the bottom feet; first sprues for injection molding are arranged on the protrusions; second sprues are arranged on the plate face of the fixed mold body; the second sprues and the first sprues are located on the same face of the fixed mold body; a feeding frame for being communicated with the first sprues and the second sprues is arranged on the other face of the fixed mold body; an injection molding opening connected with a nozzle of an injection molding machine is arranged on the feeding frame. One sprue is additionally arranged on each protrusion of the fixed mold body, it is ensured that injection molding of the tray bottom feet can reach the standard, and meanwhile injection molding efficiency is improved.

Description

technical field [0001] The present invention relates to a mold, more specifically, it relates to a tray mold for convenient injection molding of feet. Background technique [0002] Injection mold is a tool for producing plastic products, which can mass produce some plastic parts with complex shapes. The injection mold is usually composed of a movable mold and a fixed mold. During production, the mold is installed in the injection molding machine, and the injection molding machine is used to inject the heated and melted plastic into the cavity of the injection mold by high pressure. After cooling and solidification, the injection molding machine pulls The movable mold is separated from the fixed mold, and then the injection-molded finished product is pushed out by the ejector mechanism to complete one injection. [0003] In the process of injection molding larger plastic products, the molten plastic on the injection molding machine is injected into the cavity through multipl...
