Description

Technical Field

[0001] This utility model relates to the field of freezer manufacturing technology, specifically to a freezer inner liner winding mold. Background Technology

[0002] The basic function of a freezer is refrigeration, maintaining a suitable low temperature inside. A refrigeration system generally consists of four basic components: a compressor, a condenser, a capillary tube or thermostatic expansion valve, and an evaporator. The refrigerant is a liquid that boils at low pressure and low temperature, absorbing heat during boiling. The refrigerant circulates continuously in the refrigeration system. The compressor increases the gas pressure of the refrigerant, creating liquefaction conditions. As it passes through the condenser, it condenses and releases heat. Then, as it passes through the capillary tube, its pressure and temperature decrease, and finally, as it passes through the evaporator, it boils and vaporizes, absorbing heat. Modern refrigerators also utilize cooling diodes, which have no complex mechanical devices, but are less efficient and are used in smaller refrigerators. In the production process of freezers, to improve production efficiency, specialized tubing winding equipment is usually used to wind copper tubing around the outer side of the inner liner.

[0003] As disclosed in the patent announcement CN214212006U, a refrigerator inner liner winding mold specifically relates to the field of refrigerator manufacturing equipment technology. It includes a mold body, an inner liner sleeved on the outside of the mold body, and a refrigeration tube wound around the outside of the inner liner. The bottom of the mold body has a housing. The mold body includes a base and two feeding plates, which are located on both sides of the base. This invention uses an electric cylinder to move the sleeve and bushing upwards. The bushing, through a support rod, moves the feeding plate upwards, pushing the inner liner out of the mold body for easy removal. During upward movement, the support rod gradually embeds into the inside of the bushing. The bushing rotates through the engagement of a threaded groove and a protrusion, while the support rod also gradually embeds into the inside of the bushing. The threaded groove, through the protrusion, restricts the support rod, preventing wobbling during movement. The use of a slider and a groove enhances the stability of the feeding plate during movement. However, the structure of this utility model is relatively complex, and its maintenance is not very convenient. It also lacks measures to flexibly adjust the working width of the mold, and its application range is relatively narrow. To address this, we have proposed a cooling cabinet inner liner winding mold, which simplifies the structure, solves the problem of adjusting the working width of the mold, and improves the ease of use and practical effect of this utility model. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for winding tubes inside a freezer, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A refrigerator inner liner winding mold includes a mounting plate. A mold adjustment mechanism is fixedly installed at the top of the mounting plate, and a rotating mechanism is fixedly connected to the bottom of the mounting plate. The mold adjustment mechanism includes an adjustment groove, a servo motor is fixedly installed on one side of the adjustment groove, and a positive and negative threaded rod is fixedly connected to the output end of the servo motor. One end of the positive and negative threaded rod is rotatably connected to the inner wall of the adjustment groove. The mold adjustment mechanism also includes inner liner support plates. Two inner liner support plates are provided. Both inner liner support plates have I-shaped slots and threaded holes. I-shaped slide rails are slidably connected through the I-shaped slots, and both ends of the I-shaped slide rails are fixedly connected to the inner wall of the adjustment groove.

[0007] Preferably, a limiting ring is provided at the midpoint of the positive and negative threaded rods, and the two inner liner support plates are symmetrically arranged with respect to the limiting ring. The positive and negative threaded rods pass through the inner liner support plates and are threadedly connected.

[0008] Preferably, the rotating mechanism includes a connecting base plate, the mounting base plate having a first mounting hole, and the connecting base plate having a second mounting hole corresponding to the first mounting hole.

[0009] Preferably, four first mounting holes are provided, and the four first mounting holes are evenly distributed at the four corners of the mounting base plate. The first mounting holes and the second mounting holes are equipped with mounting bolts.

[0010] Preferably, the bottom end of the connecting base plate is fixedly connected to the output end of the rotary motor, the rotary motor is fixedly installed on the top end of the base plate, and the base plate has fixing through holes at its four corners.

[0011] Preferably, the I-shaped slot is symmetrical to the threaded hole, the threaded hole is located on the center line of the inner liner support plate, and a control panel is provided on the side of the adjustment slot near the servo motor, and the control panel is electrically connected to the servo motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This refrigerator inner liner winding mold uses a servo motor to drive the forward and reverse threaded rods to rotate, which in turn drives two inner liner support plates to move relative to or away from each other along an I-shaped slide rail. This achieves the effect of adjusting the distance between the two inner liner support plates, making it suitable for winding refrigerator inner liners of different lengths and expanding its application range. At the same time, it also makes it easier to reduce the distance between the inner liner support plates and increase the gap between the inner liner support plates and the inner liner after the inner liner winding is completed, thereby reducing demolding resistance and improving demolding efficiency.

[0014] 2. This refrigerator inner liner winding mold uses two I-shaped slide rails inside the adjustment groove to pass through and slide to the inner liner support plate, so that the two inner liner support plates can maintain good stability when moving relative to each other, thereby ensuring the positional accuracy of the inner liner during winding and ensuring the quality of the inner liner winding operation.
