Abstract
The utility model discloses a four-rod mechanism side loose piece synchronous core-pulling structure of blister dies of a refrigerator and a freezer box liner. A support (1) is fixed to a die body (6), one end of a cylinder (2) is fixed to the support (1), a pushing plate (4) is arranged at the other end of the cylinder (2), a hinge seat (8) is fixedly arranged on a first moving block (5) and a second moving block (9) respectively, and two ends of the pushing plate (4) are respectively connected to the hinge seats (8) on the first moving block (5) and the second moving block (9) through hinges (7). By the aid of the structure, the problems that the box liner is damaged, deformed and scratched caused by the demolding of a traditional box liner blister die are solved, the synchronicity of die moving blocks is improved, the service life of the die is improved, the cost is reduced, the inner structure of the die is simplified, and the assembly and the maintenance are convenient.
Description
Technical field
The utility model relates to a kind of mold releasability structure, particularly relates to the synchronous pulled core structure of a kind of refrigerator case courage plastics suction mould four-bar mechanism side loose piece.
Background technology
1, the existing refrigerator of the first, refrigerator case courage tradition plastics sucking moulding mould is characterized in that: there is not any demolding structure in counterdie.After finishing, foaming utilizes the distortion forced stripper mechanism of material.This mould that does not have a demolding structure can only be made relatively simple product, and high to the employed material toughness reguirements of product, has increased the manufacturing cost of refrigerator, refrigerator.
2, the existing refrigerator of the second, refrigerator case courage tradition plastics suction mould is characterized in that: mould left and right sides slide block respectively has one group of cylinder, independently drives respectively slide block separately, reaches the purpose of the demoulding.The mould of this structure is in order to guarantee the synchronous of two groups of cylinders, and is high for the production equipment air supply requirement, and the movable block of oblique movement makes cylinder be subjected to force unbalance separately, easily causes cylinder to damage, and causes stopping production.
The utility model content
Technical problem to be solved in the utility model provides a kind of guard box courage plastics suction mould when producing, and the both sides movable block can be synchronously, and the demoulding is easy, the synchronous pulled core structure of refrigerator case courage plastics suction mould four-bar mechanism side loose piece of cylinder long service life.
In order to solve the problems of the technologies described above, the synchronous pulled core structure of refrigerator case courage plastics suction mould four-bar mechanism side loose piece that the utility model provides, comprise die body, the first movable block and the second movable block, support is fixed on the described die body, one end of cylinder is fixed on the described support, the other end of described cylinder is provided with push pedal, all be fixed with hinge seat on described the first movable block and the second movable block, the two ends of described push pedal are hinged by the described hinge seat on hinge and described the first movable block and the second movable block respectively.
Described support is provided with linear bearing, and described push pedal is provided with the guide post that is inserted in the described linear bearing.
Adopt the synchronous pulled core structure of refrigerator case courage plastics suction mould four-bar mechanism side loose piece of technique scheme, the case courage is in the plastic uptake process, and mould is closed, cylinder bounces back, the mould movable block sinks with guide rail.During die sinking, cylinder is subject to the equipment air feed, ejects motion, drives the push pedal campaign, and the both sides movable block that is connected through the hinge in the push pedal is moved obliquely upward along guide rail.
The utility model changes the asymmetric demoulding of traditional two cylinders into the single-cylinder symmetrical demoulding, the case courage damage that its structure and operation principle cause in the time of can the very simple and effective solution conventional boxes courage plastics suction mould demoulding, distortion, scratch, increase the synchronism of mould movable block, improve die life, reduce production costs and simplify the mould inside structure, convenient for assembly, maintenance.
In sum, the utility model is a kind of case courage damage that causes when avoiding the demoulding of case courage, distortion, scratches, the synchronism that adds the mould movable block, improve die life, simplify the mould inside structure, and the synchronous pulled core structure of refrigerator case courage plastics suction mould four-bar mechanism side loose piece simple in structure, easily manufactured, easy to maintenance, dependable performance.
