Inclined ejection structure of injection mold

Abstract

The invention discloses an inclined ejection structure of an injection mold. The inclined ejection structure of the injection mold comprises a bottom plate, wherein first molds are fixedly assembled on the upper surface of the bottom plate; supporting rods are fixedly assembled on the left side and the right side of the upper surface of the bottom plate; a top plate is fixedly assembled at the topends of the two supporting rods; air cylinders are fixedly assembled on the left side and the right side of the lower surface of the top plate; and second molds matched with the first molds are fixedly assembled at the bottom end of the two air cylinders. Through the matching of a round plate and a sleeve as well as matching of linking rods and connecting rods, the connecting rods are pulled to swing, the connecting rods drive a push plate to drive the second molds to move upwards, the first connecting rod is driven to swing under the elastic action of a first spring through the matching of alantern ring and the first spring as well as the matching of a stop rod and a stop block, the stop rod is clamped to the bottom end of the stop block, the position of the lantern ring is limited, andthe demoulding is assisted while the first molds are supported, so that the flexibility is improved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of an injection mold inclined roof structure, and specifically relates to an injection mold inclined roof structure. Background technique [0002] Injection molding is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to melting plastic by heat. The injection molding machine is injected into the mold cavity under high pressure, and after cooling and solidification, the molded product is obtained. The injection mold is composed of a moving mold and a fixed mold. On the template, the movable mold and the fixed mold are closed during injection molding to form the pouring system and the cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic product. When ...

[0002] Injection molding is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to melting plastic by heat. The injection molding machine is injected into the mold cavity under high pressure, and after cooling and solidification, the molded product is obtained. The injection mold is composed of a moving mold and a fixed mold. On the template, the movable mold and the fixed mold are closed during injection molding to form the pouring system and the cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic product. When designing the molding part, it is first necessary to consider the properties of the plastic, the geometry of the product, Dimensional tolerance and use requirements to determine the overall structure of the cavity, followed by selecting the parting surface, the position of the gate and the vent hole and the demoulding method according to the determined structure, and finally design and determine each part according to the size of the control product The combination of parts, in order to reduce the heavy workload of mold design and manufacturing, most of the injection molds use standard mold bases. Existing injection molds usually require inclined roof structures to maintain stability during use. The connection of the inclined ejector rod basically adopts pin positioning, and the screw is locked, and the flexibility is poor in the process of use.
