Problems solved by technology

[0004] (1) The stability of the system controlling the brake position of the second plate machine is poor, and the complex design of the hydraulic system and pipeline layout makes the appearance huge, and the large number of required hydraulic components leads to higher costs;
[0005] (2) The existing mold clamping control system usually uses a zero-leakage valve to seal the mold clamping cylinder during the mold clamping operation, so as to realize the precise positioning of the brake components, but in the actual working process, there is no guarantee that there will be no leakage at all , so the positioning of the brake components is not accurate enough, which affects the performance of the entire second board machine
[0006] (3) After the mold locking operation is completed, the prior art usually adopts the method of separately sealing a plurality of mold locking oil cavities to realize pressure maintenance, and each mold clamping oil cavity is maintained separately, and there is no gap between each oil cavity. Connected, this structure leads to inconsistencies in the force of multiple clamping tie rods, and it is impossible to achieve absolute uniformity of the clamping force, which affects the performance of the entire second platen machine

Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0040] Such as figure 1 As shown, it is a structural schematic diagram of the oil circuit control method of the two-platen machine mode-locking control system provided by the present invention. from figure 1 It can be seen that the oil inlet passage 1 is connected to the oil tank to supply oil to the system, the oil return passage 13 is connected to the oil tank to discharge the oil in the system, and the first oil passage 2 is connected between the oil inlet passage 1 and the main oil passage 17 . The clamping ...

Abstract

the invention discloses a two-plate type mold locking control system and an oil way control method thereof, and relates to the technical field of injection molding and compression molding equipment. The two-plate type mold locking control system comprises a main stop valve, switch valves and a decompression unit; the main stop valve is arranged on a main oil way and controls the on-off states of the main oil way and a first oil way; the switch valves are connected to mold locking oil cylinder assemblies and form execution units; when any one of the switch valves is closed, the closed switch valve guides oil in the main oil way back to the main oil way, the oil in the mold locking oil cylinder assembly corresponding to the closed switch valve is guided back to the mold locking oil cylinderassembly, and therefore the main oil way and the mold locking oil cylinder assembles can be closed; and the decompression unit controls the on-off states of the main oil way and an oil return way. Theinvention further discloses the oil way control method applied to the two-plate type mold locking control system. The two-plate type mold locking control system and the oil way control method thereofhas the advantages that accurate positioning of the position of a brand-type brake can be realized, reasonable pressure maintaining of the system can be realized, the design of the control system canbe more reasonable and reliable, the cost can be lower, and the performance of a two-plate plastic injection molding machine can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of injection molding and die-casting equipment, in particular to a two-platen machine mold-locking control system and an oil circuit control method thereof. Background technique [0002] At present, in the plastic processing, metal die-casting and rubber processing industries, most of the clamping mechanisms used in injection molding equipment and die-casting molding equipment adopt the two-platen type (referred to as the two-platen machine). The two-plate mold clamping mechanism has been widely used because of its simple and compact structure and ease of use. The mold opening and closing of the second plate machine is a cyclic process. Each cycle includes mold clamping, mold locking, oil cylinder reset, brake, high pressure mold clamping, injection, pressure relief and mold opening. After the mold is closed, the second plate machine Provide sufficient clamping force to the mold to resist the cavity pressur...
