Problems solved by technology

[0002] At present, injection molds are usually combined with a single press and a mold to complete the lifting and pressing of the upper mold. The efficiency is low. If the mold is added, the press needs to be added to cooperate, and the cost is increased. And when unloading, It is easy to generate residual debris in the mold cavity, which needs to be shut down for cleaning, which affects production efficiency. Therefore, an improved technology is urgently needed to solve this problem in the prior art

Abstract

The invention discloses an alternating injection mold. The alternating injection mold is characterized in that a first lifting piece is arranged on the upper surface of a first upper mold, and first long guide rods at the lower end of the first upper mold and first long guide sleeves in a first lower mold are in one-to-one correspondence and are in sliding connection; a second lifting piece is arranged on the upper surface of a second upper mold, and second long guide rods at the lower end of the second upper mold and second long guide sleeves in a second lower mold are in one-to-one correspondence and are in sliding connection; the two ends of a connecting beam are connected with the side edges of the first lower mold and the second lower mold correspondingly, and a supporting rod is vertically arranged in the middle of the upper surface of the connecting beam; a balance rod is arranged on a U-shaped frame through a rotating shaft; and sliding grooves in the two ends of the balance rod are movably connected with the first lifting piece and the second lifting piece respectively through shaft pins. According to the alternating injection mold, the structure is reasonable; when one mold is used for injection molding, the other mold is used for discharging, cooling and cleaning, so that rapid circulating manufacturing is achieved, and efficiency is greatly improved; and the service life of the molds is guaranteed, and the use number of pressing machines does not need to be increased.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an alternating injection mold. Background technique [0002] At present, injection molds are generally combined with a single press and a mold to complete the lifting and pressing of the upper mold. The efficiency is low. If more molds are added, the press needs to be added to cooperate, which increases the cost, and when unloading, It is easy to generate residual debris in the mold cavity, which needs to be shut down for cleaning, which affects production efficiency. Therefore, an improved technology is urgently needed to solve this problem in the prior art. Contents of the invention [0003] The purpose of the present invention is to provide an alternate injection mold, a balance frame is arranged between the first mold and the second mold, and the first upper lifting part is realized through the cooperation of the balance bar with the first lifting part and the secon...
