Mould with swing rotation mechanism

Abstract

The invention discloses a mold with an oscillating rotating mechanism. The mold comprises a fixed die and a movable die, wherein the fixed die comprises a panel, a fixed die frame and a fixed die core, the movable die comprises a soleplate, a movable die frame, a movable die core and an ejection mechanism, a product forming cavity is formed on the junction of the fixed die core and the movable die core, and an oscillating rotating mechanism is arranged in the fixed die core. Two insert blocks (an oscillating core pulling mechanism and a core pulling block) for forming an arc handle and a lock position of a finished product are assembled together, the two insert blocks are driven to oscillate by the panel in mold stripping, the two insert blocks are separated from the product, the separation can be completed by one step, and the die sinking time can be saved; the mold is simple in structure and small in size and can be formed through a small-tonnage injection molding machine. The cost is low, the yield can be improved by one third for each time compared with that of the traditional product, and the production efficiency is high. The mold belongs to the technical field of molds.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to a mold with an oscillating and rotating mechanism. Background technique [0002] Due to the structure of certain products, such as a curved handle on the outer end of the refrigerator pull box, and a buckle (through hole) located under the curved handle, the existing mold needs to go through the slider from the buckle first when opening the mold. The core-pulling mechanism that slides out and then separates from the arc-shaped part of the molded product through the rotating mechanism requires two processes to complete. The mold is equipped with two mechanisms (slider mechanism, rotating core-pulling mechanism) to complete the mold opening work successively. The application of this technology is feasible from the perspective of the mold, but from the perspective of enterprise production, it is not in line with its economic benefits and Energy saving and environmental protection re...

Problems solved by technology

The design of the above mechanism will directly lead to a large mold size and the use of a large-tonnage injection molding machine

Such a mold has the following disadvantages: the structure of the mold is complex and the volume is large, resulting in a large tonnage of the injection molding machine used, a long molding cycle and high cost during production; 540 pieces of products are produced per shift, and the production efficiency is not high
