Description

Technical Field

[0001] The invention relates to a glass glue bottle mould, in particular to a one-outlet multi-glass glue bottle mould. Background Art

[0002] Chinese Patent No. ZL201420433321.6 disclosed on December 10, 2014 a core positioning structure of a glass glue bottle mold, comprising a fixed mold plate and a movable mold plate, the fixed mold plate is provided with a pouring port, the movable mold plate is composed of a bottom plate and a front plate, the bottom plate is provided with a mold core, the front plate is provided with a mold cavity, the outer surface of the mold core and the inner wall of the mold cavity and the fixed mold plate together form an injection cavity, the center of the mold core is provided with an inner needle movable along the axis of the mold core, the front end of the inner needle extends out of the mold core and is provided with an injection flow channel connected to the pouring port, the rear end of the inner needle is transmission-connected with a driving device, by controlling the inner needle to move forward, when the front end of the inner needle is connected to the pouring port of the fixed mold plate, the mold core changes from a cantilever beam structure to a simply supported beam structure to ensure the verticality of the mold core and the mold cavity, thereby ensuring that the injection molded product will not be eccentric, and then, in the later stage of injection molding, the inner needle is withdrawn and the glue is supplemented to achieve the final injection molding. The rear end of the inner needle is connected to the top plate, and a wedge block is provided on the top plate. The driving device is a cylinder, and the piston rod of the cylinder is provided with a slider with an inclined surface corresponding to the wedge block, and the inclined surface of the slider and the inclined surface of the wedge block slide and cooperate with each other. When the structure is provided with multiple injection cavities, since each inner needle is driven by the same cylinder, the stroke is fixed. However, since there are more or less length errors between each inner needle, although these errors are very small, but since the mold is specially designed for batch production, its disadvantages will be revealed under long-term work, for example: after the longer inner needle first contacts the pouring port, it will continue to be pressed, so it will bend and deform, affecting the mold core and causing the mold core to shift; in addition, since the shorter inner needle cannot contact the pouring port, 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, since the plastic at the pouring gate is connected to the molded product, the plastic molding at the pouring gate may occasionally be well fixed, resulting in it being difficult to break and the product being unable to fall out. At this time, the product that cannot fall off the fixed template needs to be manually knocked down, reducing production efficiency. Summary of the invention

[0054] The first elastic member, the second elastic member, the first connecting rod and the second connecting rod are not shown in the figures.

[0055] Its working principle is: after the mold is closed, the oil cylinder pushes the inner needle forward, so that the suspended end of the mold core is supported by the inner needle, thereby improving its rigidity and concentricity with the core sleeve. After the cavity (except the contact point between the inner needle and the injection nozzle) is filled with plastic, the inner needle can retreat and the space between the inner needle and the injection nozzle is filled with plastic, so that the cavity is filled with plastic; then, the mold can be opened. When the mold is opened, the wedge-shaped push block 8 gradually loses its force on the slider, and the slider is moved under the action of the second elastic member. Fig.11 Move in the direction of the middle arrow to open the slide and buckle with the front end of the injection-molded glass glue bottle. At the same time, when the crests and troughs of the waveform surfaces of the slider and the limit block are relative, the slider bounces backward under the action of the first elastic member, so the product is pulled away from the glue injection nozzle to ensure that the product falls automatically, thereby improving production efficiency.
