Problems solved by technology

[0004] At present, when the two-platen injection molding machine with a spring mold is opened, due to the spring force, after the mold is clamped and the pressure is released, the moment the gate is opened, due to the excessive spring force, it will be pushed to the back of the template, and the spring force will act on the gate. On the machine, when the brake is opened, due to the contact surface of the brake system, it will produce a certain impact sound, which will affect the quality of the equipment

Embodiment 1

[0033] Please refer to Figure 1-Figure 4 , the mold opening method of the spring mold of the two-plate injection molding machine, which comprises the steps of:

[0034] S1, the clamping system 100 releases the pressure so that the clamping force of the male mold 520 and the female mold 530 is reduced to zero;

[0035] S2, the switch mold system 200 first drives the spring mold 500 to break the mold, and then outputs an overcoming force to overcome the spring force of the spring mold 500 and close the spring mold 500;

[0036] S3, the brake system 300 drives the brake machine 400 to open the brake;

[0037] S4, the switch mold system 200 drives the spring mold 500 to open the mold.

[0038] Specifically, after the clamping system 100 releases the pressure, the spring mold 500 has no clamping force, and the switch mold system 200 drives the spring mold 500 to break the mold. After the mold break is completed, the switch mold system 200 outputs an overcoming force to overcome ...

Embodiment 2

[0049] Such as Figure 1-Figure 4 , the driving system of the spring mold of the two-platen injection molding machine, including:

[0050] The mold clamping system 100 is used to provide mold clamping force for the male mold 520 and the female mold 530;

[0051] The switch mold system 200 is used to drive the spring mold 500 to break the mold, output the overcoming force to overcome the spring force of the spring mold 500 to make the spring mold 500 close the mold; the switch mold system 200 is also used to drive the spring mold 500 to open and close the mold;

[0052] The brake system 300 is used to drive the brake 400 to lock and open the brake. Before the mold is opened, the brake is in the brake state, and the brake 400 is used to lock the spring mold 500 in the mold closing state.

[0053] In this embodiment, the operation sequence of the mold locking system 100 , the mold opening and closing system 200 , and the brake system 300 can be controlled by PLC.

Abstract

The invention discloses a die-opening method and a driving system for a spring die of a two-plate injection molding machine. The driving system is characterized in that the driving system comprises adie locking system, a die opening and closing system and a braking system. The die-opening method comprises the steps that 1, the die locking system relieves pressure to make die locking force of a male die and a female die be reduced to zero; 2, the die opening and closing system drives the spring die firstly to be broken and then outputs overcome force to overcome spring force of the spring dieto make the spring die to be assembled; 3, the braking system drives a brake machine to open a brake in place; and 4, the die opening and closing system drives the spring die to be opened. According to the die-opening method and the driving system for the spring die of the two-plate injection molding machine, die assembling motion exists in the die opening process, the spring force of the spring die is overcome by utilizing the overcome force provided by the die opening and closing system, the situation that the spring force acts on the brake machine is avoided, thus the brake machine can openthe brake smoothly, and the overcome force can be set according to the spring force.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a mold opening method and a driving system for a spring mold of a two-platen injection molding machine. Background technique [0002] With the development of the mold industry, the technology of molds with springs is developing rapidly, and the corresponding injection molding machines also need to consider the functional requirements of spring molds to ensure that the objective factors of springs can be considered in the process of mold closing and mold opening. [0003] The traditional crankshaft injection molding machine can basically meet the production of spring molds due to the crankshaft force after the mold is closed. However, the clamping mechanism of the two-platen injection molding machine is completely different in principle. At this stage, there is no unified and industry-accepted method for two-platen injection molding machines to meet spring mold...
