Mold for producing multiple glass glue bottles

Abstract

The invention relates to a mold for producing multiple glass glue bottles and the mold for producing multiple glass glue bottles comprises a fixed mold plate and a movable mold plate, the fixed mold plate is provided with a glue injection nozzle, the movable mold plate is provided with two or more mold core mounting cavities, mold core assemblies are arranged in the mold core mounting cavities, each mold core assembly comprises a core sleeve, a mold core and an inner needle, and two sliding blocks are arranged at the outer end, corresponding to the glue injection nozzle, of the fixed mold plate. Two sliding positions are arranged at the joint of the two sliding blocks, are respectively connected with one sliding block, and do opening and closing motion; and limiting blocks are arranged atthe ends, corresponding to the sliding blocks, of the fixed mold plate, waveform faces are arranged on the opposite surfaces of the sliding blocks and the limiting blocks respectively, and first elastic pieces are arranged between the sliding blocks and the fixed mold plate. Oil cylinders are in one-to-one correspondence with the inner needles; and pistons of the oil cylinders push the inner needles to move. When the mold is opened, the sliding positions can be opened and move towards the direction of the movable mold plate, a product is pulled away from the glue injection nozzle, and the product is ensured to automatically fall off, so that the production efficiency is improved; and in addition, each inner needle is controlled by one independent oil cylinder, so that the inner needles areprevented from being bent, and the yield is improved.

Description

technical field [0001] The invention relates to a glass plastic bottle mould, in particular to a multi-glass plastic bottle mould. Background technique [0002] Chinese Patent No. ZL201420433321.6 disclosed a core positioning structure for a glass plastic bottle body mold on December 10, 2014, including a fixed template and a movable template. The fixed template is provided with a pouring port, and the movable template is composed of a bottom plate and a front plate , a mold core is set on the bottom plate, and a mold cavity is set on the front plate. The outer surface of the mold core, the inner wall of the mold cavity and the fixed template jointly form an injection molding cavity. The center of the mold core is provided with an inner needle that can move along the axis of the mold core. , the front end of the inner needle protrudes out of the mold core, and is provided with an injection flow channel connected with the sprue, and the rear end of the inner needle is connect...

AI Technical Summary

Problems solved by technology

However, due to the more or less length errors between the inner needles, although these errors are very small, because the mold is specially designed for mass production, its disadvantages will be revealed under long-term work, for example: After the long inner needle touches the sprue first, it will continue to be pressed, so it will be bent and deformed, affecting the core and causing the core to shift; in addition, because the shorter inner needle cannot contact the sprue, the said In other words, the mold core is still in a suspended state, and it is also easy to be skewed when the injection molding is squeezed

[0003] In addition, after the mold of this structure is opened, because the plastic of the sprue is connected with the molded product, occasionally the plastic of the sprue is fixed better, which leads to the problem that it is not easy to break and the product cannot fall out. At this time, it is necessary to manually Lay off the products that cannot be dropped on the fixed template, reducing production efficiency
