Description

Technical Field

[0001] The utility model belongs to the technical field of deep freezing boxes, and in particular relates to a deep freezing box which is convenient for taking out materials. Background Art

[0002] Cryogenic treatment is a complementary process to heat treatment. It is a process in which the workpiece is placed in a certain low-temperature environment and treated according to a certain process. Studies have shown that cryogenic treatment can effectively improve the mechanical properties of the material, such as wear resistance, dimensional stability, strength and toughness, thereby improving the quality of the workpiece, extending its service life, and ultimately reducing production costs.

[0003] In the related art, a cryogenic box is used for mold processing. The operator processes the mold through the cryogenic box, but the inner cavity of the cryogenic box is usually deep. After the mold processing is completed, it is inconvenient to remove the mold from the inner cavity of the cryogenic box, which has obvious shortcomings. Utility Model Content

The screw motor drives the coaxial bidirectional reciprocating screw to rotate and drive the movable support plate to move horizontally toward each other. The front and rear ends of the movable support plate drive the support arms to simultaneously support and lift the front and rear sides of the load-bearing plate; the two ends of the load-bearing plate move up and down along the guide rods through the guide blocks, ensuring the stability of the load-bearing plate's lifting and lowering, making it convenient to place or remove the mold on the load-bearing plate, and bringing great convenience to the operator.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a deep cold box for convenient material retrieval, comprising a box body, a box cover connected to the top of the box body, a first slide groove provided on the inner walls on both sides of the box body, a guide rod installed in the first slide groove, a load-bearing plate sliding on the guide rod through a guide block, a driving support structure for driving the load-bearing plate to move up and down is installed at the bottom of the box body, and the driving support structure includes a driving mechanism and a support structure.

[0006] As an optimal solution for a deep-freeze box that is convenient for material retrieval in the utility model, the driving mechanism includes a screw motor and a coaxial bidirectional reciprocating screw; the coaxial bidirectional reciprocating screw is installed in a second slide groove opened at the bottom of the box body through a screw seat, and one end of the coaxial bidirectional reciprocating screw passes through the box body and is connected to the screw motor drive; the coaxial bidirectional reciprocating screw is movably connected to a support structure through a screw slider.

[0007] As an optimal solution for a deep cold box that is convenient for material retrieval according to the utility model, the support structure includes a movable support plate and a support arm. The movable support plate is installed on a screw slider, and the movable support plate is arranged directly below the two ends of the load-bearing plate. The front and rear ends of the movable support plate are connected to the support arm through a pin shaft, and the upper end of the support arm is connected to the front and rear side surfaces of the middle part of the load-bearing plate through a pin shaft.

[0008] As a preferred solution of the deep freezer for convenient material retrieval of the utility model, the movable support plate is driven by a screw motor to move horizontally in the direction of or in the opposite direction of the coaxial bidirectional reciprocating screw via a screw slider.

[0009] As a preferred solution of the deep freezing box for convenient material removal of the utility model, a control switch box electrically connected to the screw motor is installed on the side of the box body.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The screw motor of the utility model drives the coaxial bidirectional reciprocating screw to rotate, driving the movable support plate to move horizontally in opposite directions. During the movement of the movable support plate, the support arm connected to the pin shaft is driven to slowly change from an inclined state to a vertical state. The support arm can drive the load-bearing plate to rise and fall, and the load-bearing plate can move to the position of the opening at the top of the box body, which is convenient for the operator to remove the mold from the load-bearing plate.
