Double-flared-opening plastic part forming mold

Abstract

A double-flared-opening plastic part forming mold comprises a fixed mold and a movable mold which are arranged in the vertical direction; a pouring head is located on one side of the fixed mold and one side of the movable mold, and the other side of the fixed mold and the other side of the movable mold are provided with a limiting block; the fixed mold, the movable mold, the limiting block and thepouring head jointly form a double-flared-opening injection molding part cavity, and the double-flared-opening injection molding part cavity is used for injection molding of a double-flared-opening injection molding part; the pouring head stretches into the double-flared-opening injection molding part cavity and keeps a certain distance away from the limiting block, and a runner is formed and located at the center of the double-flared-opening injection molding part; the pouring head can move left and right along with a spiral rod; the limiting block can be moved left and right through a screwin front of a driving motor; and a plurality of hydraulic rods are arranged under the movable mold and controlled to go up and down through a hydraulic system. The double-flared-opening plastic partforming mold has the following beneficial effects that a double-flared-opening plastic part can be formed at a time through injection molding, the precision and the efficiency are high, in addition, operation is easy, and the automation degree is high.

Description

Technical field [0001] The invention belongs to the field of molds, and specifically relates to a molding mold for upper and lower bell mouth plastic parts and a discharge method thereof. Background technique [0002] With the rapid development of the plastic industry, the application of plastic molds has become more and more extensive, and injection molding of upper and lower bell mouth plastic parts is required. [0003] However, the molding method of the upper and lower bell mouth plastic parts is very troublesome. It is necessary to inject half of the bell mouth on an injection molding machine, and then after demolding, put half of the bell mouth on another injection molding machine. Then perform two-shot injection, connect the interface, and then take off the other half of the mold to form Figure 4 The upper and lower bell mouth plastic parts are shown, but the connection position of the upper and lower bell mouth plastic parts is obvious, and there are many operation steps, c...
