Abstract
The utility model discloses a core pulling mechanism of a refrigerator door liner vacuum forming mould. The core pulling mechanism comprises upper and lower fixing seats fixedly mounted on the back of the mould, wherein the upper and lower fixing seats are hinged with upper and lower core pulling blocks respectively; the front ends of the upper and lower core pulling blocks respectively pass through a through hole in the mould and extend into the mould; the core pulling mechanism comprises a bidirectional cylinder and upper and lower fisheye joints; the end parts of two piston rods of the bidirectional cylinder are connected with upper and lower connecting rods respectively; the front ends of the upper and lower fisheye joints are hinged with the rear ends of the upper and lower core pulling blocks respectively; the rear ends of the upper and lower fisheye joints are fixedly connected with the front ends of the upper and lower connecting rods respectively. The core pulling mechanism disclosed by the utility model is simple in structure and easy to mount and maintain, solves the problems of manufacturing cost increase and inconvenience in maintenance of the original mould adopting a connecting rod mechanism, guarantees the cooperation and action stability between the core pulling blocks and the main body of the mould, reduces the production cost, and improves the production efficiency.
Description
Technical field
The utility model relates to refrigerator manufacturing equipment field, specifically a kind of refrigerator door core vacuum forming mold core-pulling mechanism.
Background technology
Refrigerator doors inner bag both sides are generally designed with the buckle of hanging fruit and vegetable box, and Packing Machine, when moulding inner door, owing to there being protruding boss on product, is difficult to the demoulding when the demoulding.What original mould structure adopted is that linear bearing is equipped with in mould both sides, looses core linkage is housed between piece.During the demoulding, linkage drives the piece of loosing core to move to reach the object of the demoulding, because the parts of linkage are many, has increased processing cost, and has been unfavorable for I&M, and in addition, linear bearing also needs periodic replacement, has reduced production efficiency.
Utility model content
The purpose of this utility model be to provide a kind of simple in structure, be easy to install and the refrigerator door core vacuum forming mold core-pulling mechanism of maintenance, with the stability that coordinates, moves between guarantee to loose core piece and die main body, and reduce production cost, enhance productivity.
The technical solution of the utility model is as follows:
A kind of refrigerator door core vacuum forming mold core-pulling mechanism, include the upper and lower holder that is fixedly mounted on mold backs, it is characterized in that: on described upper and lower holder, be hinged with respectively the upper and lower piece of loosing core, the front end of the described upper and lower piece of loosing core passes respectively the through hole on mould and extends in mould; Include two-way cylinder and upper and lower flake joint, the end of two piston rods of described two-way cylinder is connected with respectively upper and lower connecting rod, the front end of described upper and lower flake joint is hinged on respectively the upper and lower Kuai of loosing core rear end, and the rear end of upper and lower flake joint is fixedly connected on respectively the front end of upper and lower connecting rod.
Described refrigerator door core vacuum forming mold core-pulling mechanism, it is characterized in that: on described upper and lower holder and the middle part of the upper and lower piece of loosing core is respectively equipped with through hole, have bearing pin successively through on upper fixed seat and above loose core piece middle part and lower fixed seat and under the loose core through hole at piece middle part, the described upper and lower piece of loosing core is hinged on respectively on upper and lower holder.
The beneficial effects of the utility model:
The utility model is simple in structure, be easy to install and maintenance, solved original mould because of the manufacturing cost that adopts linkage and increase and the problem of inconvenience maintenance, the stability that coordinates, moves between guaranteed to loose core piece and die main body, reduce production cost, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, a kind of refrigerator door core vacuum forming mold core-pulling mechanism, include the upper and lower holder 2 that is fixedly mounted on mould 1 back, be hinged with respectively the upper and lower piece 3 of loosing core on upper and lower holder 2, the front end of the upper and lower piece 3 of loosing core passes respectively the through hole on mould 1 and extends in mould 1; Include two-way cylinder 4 and upper and lower flake joint 5, the end of two piston rods of two-way cylinder 4 is connected with respectively upper and lower connecting rod 6, the front end of upper and lower flake joint 5 is hinged on respectively the rear end of the upper and lower piece 3 of loosing core, and the rear end of upper and lower flake joint 5 is fixedly connected on respectively the front end of upper and lower connecting rod 6.
In the utility model, on upper and lower holder 2 and upper and lower middle part of loosing core piece 3 is respectively equipped with through hole, have bearing pin 7 successively through on upper fixed seat and above loose core piece middle part and lower fixed seat and under the loose core through hole at piece middle part, the upper and lower piece 3 of loosing core is hinged on respectively on upper and lower holder 2.
Inner container of icebox, be that product is adsorbed on mould 1 after moulding, during the demoulding, two piston rod retractions of two-way cylinder 4, upper and lower connecting rod 6 drives respectively upper and lower flake joint 5 and the upper and lower piece 3 of loosing core to take bearing pin 7 as fulcrum rotation, and after rotating to an angle, the upper and lower piece 3 of loosing core departs from respectively product, then two of two-way cylinder 4 piston rods stretch out, and the upper and lower piece 3 of loosing core resets.
Claims (2)
1. a refrigerator door core vacuum forming mold core-pulling mechanism, include the upper and lower holder that is fixedly mounted on mold backs, it is characterized in that: on described upper and lower holder, be hinged with respectively the upper and lower piece of loosing core, the front end of the described upper and lower piece of loosing core passes respectively the through hole on mould and extends in mould; Include two-way cylinder and upper and lower flake joint, the end of two piston rods of described two-way cylinder is connected with respectively upper and lower connecting rod, the front end of described upper and lower flake joint is hinged on respectively the upper and lower Kuai of loosing core rear end, and the rear end of upper and lower flake joint is fixedly connected on respectively the front end of upper and lower connecting rod.
