Embodiment 1

[0017] A new type of core-pulling and demoulding mechanism for a vacuum plastic mold for a refrigerator liner, comprising a mold body 1, a core-pulling block 2 and two cylinders 3, the core-pulling block 2 is movably installed on the mold body 1, The outer surface of the core block 2 opposite to the cylinder 3 and the friction surface with the mold body 1 are inlaid with a tin-brass alloy wear-resistant layer with a thickness of 0.1-1 mm to prevent the core block from being pulled from The process of mold body 1 being ejected and entering the core hole causes wear and tear, and there is a gap between the core hole and the core hole, which affects product performance;

[0018] The two cylinders 3 are fixedly installed in the mold main body 1 through the cylinder fixing seat 4, and are respectively installed on both sides of the radial center line of the core pulling block, and are symmetrically distributed; the piston rods of the two cylinders 5 are connected with the core-pull...

Embodiment 2

[0020] A new type of core-pulling and demoulding mechanism for a vacuum plastic mold for a refrigerator liner, comprising a mold body 1, a core-pulling block 2 and two cylinders 3, the core-pulling block 2 is movably installed on the mold body 1, The outer surface of the core block 2 opposite to the cylinder 3 and the friction surface with the mold body 1 are inlaid with a tin-brass alloy wear-resistant layer with a thickness of 0.1-1 mm to prevent the core block from being pulled from The process of ejecting the main body of the mold and entering the core hole causes wear and tear, and there is a gap between the core hole and the core hole, which affects product performance;

[0021] The two cylinders 3 are fixedly installed in the mold main body 1 through the cylinder fixing seat 4, and are respectively installed on both sides of the radial center line of the core pulling block, and are symmetrically distributed; wherein, the piston rods of the two cylinders 5. A connecting ...

Abstract

The invention discloses a novel core-pulling and demoulding mechanism of a vacuum plastic suction mould for a liner of a refrigerator. The novel core-pulling and demoulding mechanism comprises a mould body, a core-pulling block and two cylinders, wherein the core-pulling block is movably arranged on the mould body; the two cylinders are fixedly arranged in the mould body respectively by a cylinder fixing seat, and are symmetrically distributed at the two sides of the radial center line of the core-pulling block; piston rods of the two cylinders are respectively and movably connected with the core-pulling block; the two cylinders operate in a way of linkage; the piston rods of the two cylinders operate along the opposite directions. Due to the reasonable design that the two cylinders operate along the opposite directions, the rotation effect of the piston rods of the cylinder for the core-pulling block is canceled, and the rotation abrasion of the core-pulling block is effectively avoided during operation; furthermore, the two cylinders operate in a way of linkage, so that the power output of the operation of the single cylinder can be reduced, the stability of the piston rods of the cylinders can be improved during rotation, the internal vibration and the noise caused during the operation of a core-pulling mechanism are effectively reduced, and the service life of the novel core-pulling and demoulding mechanism is better prolonged.

Description

technical field [0001] The invention relates to the field of vacuum plastic-absorbing molds for refrigerator inner tanks, in particular to a novel core-pulling and demoulding mechanism for vacuum plastic-absorbing molds for refrigerator inner tanks. Background technique [0002] There are drawers, thermostats and lamps in the refrigerator. Therefore, the corresponding shape and limit bosses should be designed on the refrigerator liner, and the doors and boxes with fixed shapes and bosses should be formed by designing the core-pulling mechanism. Easy demoulding. [0003] At present, for a core-pulling mechanism with only one core-pulling block and the size of the core-pulling block is moderate, such as figure 1 The cylinder direct-push mechanism shown directly pushes the core-pulling block out of the mold. The advantages of the demoulding mechanism are simple processing and convenient assembly. However, with the improvement of the technical level, the pace of product prod...
