Description

Molds with oscillating swivel mechanism

technical field

The utility model belongs to the technical field of moulds, in particular to a mold with a swinging and rotating mechanism. the

Background technique

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 requirements. The design of the above-mentioned mechanism will directly lead to the large volume of the mold and the use of a large-tonnage injection molding machine. Such a mold has the following disadvantages: the mold structure 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 products are produced per shift, and the production efficiency is not high. the

Detailed ways

With reference to Fig. 1-shown in Fig. 4, a kind of mold with swinging and rotating mechanism of the utility model, it comprises fixed mold and movable mold, and fixed mold comprises panel 1.1, fixed mold frame 1.2 and fixed mold core 1.3, and described movable mold The mold includes a bottom plate 2.1, a movable mold frame 2.2, a movable mold core 2.3 and an ejection mechanism. The joint surface of the fixed mold core 1.3 and the movable mold core 2.3 forms a product molding cavity, and the fixed mold core 1.3 is provided with a swinging and rotating mechanism. the

The oscillating rotating mechanism includes a oscillating core-pulling mechanism 3.1 and a core-pulling block 3.2, the core-pulling block 3.2 is fixed inside the lower end of the oscillating core-pulling mechanism 3.1, the oscillating core-pulling mechanism 3.1 is hinged on the fixed mold, and the side of the oscillating core-pulling mechanism 3.1 A roller 3.3 is provided, and the roller 3.3 rolls and fits in a fixed part 3.4 with a chute, and the fixed part 3.4 is fixed on the panel 1.1 of the fixed mold. The gate position of the utility model is located on the movable mold core 2.3. The lower end of the swing core-pulling mechanism 3.1 is in the same shape as the arc part of the product to be formed. the

The angle formed between the chute of the fixing part 3.4 and the horizontal plane is 0°-60°, and the angle formed between the chute of the fixing part 3.4 and the horizontal plane in this embodiment is 0°. the
