Blow-molding mechanism for handle assembly snapping grooves in container with handle

Abstract

The invention discloses a blow-molding mechanism for handle assembly snapping grooves in a container with a handle. The blow-molding mechanism is arranged on a machine frame and is used for forming a snapping groove mold for blow-molding the snapping grooves in a bottle blowing mold when the container is subjected to blow-molding by a bottle blowing machine; the blow-molding mechanism comprises a mold mechanism and a driving mechanism, wherein the mold mechanism is slidably arranged on the machine frame, and the driving mechanism is arranged on the machine frame and is used for driving the mold mechanism to extend into the bottle blowing mold so as to form the snapping groove mold; the driving mechanism is also used for driving the mold mechanism to slide out of blow-molded containers. According to the blow-molding mechanism for the handle assembly snapping grooves in the container with the handle, disclosed by the invention, an oscillating cylinder is arranged to drive a cam to rotate, and the cam drives two sliding blocks to be close to each other or far away from each other, so that the problem that the sliding blocks cannot reset is avoided; the original sliding friction is changed into rolling friction, so that the wear among parts is effectively reduced; the oscillating cylinder is driven through low-pressure gas, so that the blow-molding mechanism is more energy-saving.

Description

technical field [0001] The invention relates to a blow-molding mechanism for a handle fitting slot on a container with a handle. Background technique [0002] In the blowing process of containers with handles, it is necessary to realize the reciprocating movement of the upper and lower handle slot molds through a mechanical mechanism, and the slot molds are generally made into a slider shape. When the container is blown, the slotted mold extends into the blowing mold, and the slotted mold retracts after the bottle blowing is completed, so that the container can be taken out from the blowing mold. [0003] The existing blow molding method generally uses high-pressure gas to make the piston push the upper and lower two slotted molds into the blowing mold for blowing. After the bottle blowing is completed, the piston and the slotted mold are reset by a spring. This method has the following disadvantages: If the container’s tightness on the slot mold is greater than the spring ...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: If the container’s tightness on the slot mold is greater than the spring force during the forming process, the slot mold cannot be reset; after long-term use, the spring will undergo permanent deformation, and the elastic force will not reach the original design Requirements: The piston drives the upper and lower two slotted molds through sliding friction, and the wear rate of the parts is relatively high
