Edge sealing mold with impermeable glue

Abstract

The invention discloses an edge sealing mold with impermeable glue. An upper mold, a middle mold and a lower mold are combined and adhered to form the edge sealing mold, the upper mold is provided with a downward projection, a groove corresponding to the projection is formed in the upper portion of the middle mold, the contact surface of the upper mold and the middle mold is coated with glue, the glue is positioned in the groove after being extruded and cannot flow into a mold cavity, a downward step is arranged on the lower portion of the middle mold, a notch corresponding to the step is formed in the upper portion of the lower mold, the contact surface of the middle mold and the lower mold is coated with glue, the glue is positioned at the step after being extruded and cannot flow into a mold cavity, the mold is provided with a pouring cup, a step structure is arranged on the lower portion of the pouring cup and connected with a mold opening in a matched manner, and the step structure can prevent the glue from entering the mold cavity. According to the mold, waste products are effectively avoided, qualification rate of finished products is greatly increased, cost is reduced, working efficiency is improved, the independent pouring cup prevents punched sand grains at the inner edge of an active mold gate from entering castings, and waste products are avoided.

Description

technical field [0001] The invention relates to the technical field of mold design for a turbocharger, in particular to an edge-sealing mold capable of preventing glue seepage. Background technique [0002] When the mold of the turbocharger is closed, it is bonded together by glue and then cast. However, the existing molds are simply plane bonding. After the mold is squeezed, the glue solution is easy to infiltrate into the mold cavity, which will cause waste products, low product qualification rate and high cost. Contents of the invention [0003] The purpose of the present invention is to provide a kind of edge-sealing mold with anti-bleeding glue step or groove on the glue brushing surface of mold clamping. [0004] The present invention is for realizing the above object, and the technical scheme that adopts is: [0005] An edge-sealing mold with anti-glue seepage, said mold is formed by combining and bonding an upper mold, a middle mold and a lower mold; [0006] Th...
