Description

Technical Field

[0001] This utility model relates to the field of EVA processing equipment technology, and in particular to an EVA hot and cold setting device. Background Technology

[0002] EVA molding machines are devices for hot-pressing plastic materials. They apply pressure to the raw material through hot pressing, causing the plastic material on the processing plate to solidify and then cool. However, existing technologies still have the following drawbacks:

[0003] Existing molding machines require cooling and shaping of raw materials after hot pressing. This process often takes a long time to switch between control and operation, which is not conducive to mass production.

[0004] Chinese patent CN 211842837 U discloses an EVA hot and cold pressing conversion mold forming machine. Its working principle is as follows: after the hot pressing block is completed, the cooling plate is automatically pushed upwards by the sliding groove spring to contact the conduction plate. The conduction plate then conducts cold air to shape the hot-pressed workpiece. By improving the equipment structure, the condenser can automatically rise during the upward movement of the hot pressing plate after hot pressing, directly cooling and shaping the newly formed material without the need for manual cooling conversion. However, the movement of the condenser in this forming machine is achieved through the sliding groove spring. Since the spring is a consumable part, spring damage and replacement can easily increase downtime and maintenance time, reducing production efficiency. Utility Model Content

[0005] Therefore, it is necessary to provide an EVA hot and cold setting device to address the problem mentioned above that EVA hot and cold pressing conversion mold forming machine is prone to increased downtime due to spring damage requiring replacement, which increases maintenance downtime and reduces production efficiency.

[0041] Please see Figure 1 An EVA hot and cold setting device 100 according to one embodiment of the present invention includes a frame 10, a hot pressing plate 20, a cooling plate 30, a condenser pipe 40, a movable plate 50, and a driver. The hot pressing plate 20 and the cooling plate 30 are vertically and correspondingly arranged on the frame 10. The condenser pipe 40 is disposed inside the cooling plate 30. The movable plate 50 is disposed between the hot pressing plate 20 and the cooling plate 30. The driver is fixedly disposed on the frame 10. The telescopic end of the driver passes through the cooling plate 30 and is fixedly connected to the movable plate 50. The movable plate 50 moves up and down under the drive of the driver.

[0042] Please see Figure 1 and Figure 2 The hot press plate 20 has a heating chamber, and a heating tube is installed in the heating chamber. The cooling plate 30 has a through hole 35 in its middle, through which the telescopic end of the driver passes and is fixedly connected to the movable plate 50. The cooling plate 30 includes a base plate 31 and a conductive plate 32 connecting the base plate 31. The base plate 31 has two accommodating cavities 33, located at the front and rear ends of the base plate 31, and connected by the two connecting channels 34. The two connecting channels 34 are located on the left and right sides of the through hole 35. An air inlet pipe 37 is fixedly installed at the rear end of the base plate 31. Multiple air inlet pipes 37 are spaced apart along the length of the cooling plate 30. The conductive plate 32 is fixedly connected to the base plate 31 by screws. The conductive plate 32 is provided with a positioning post 36, and the positioning post 36 has an axially arranged air outlet 38. The conductive plate 32 is a copper plate or an aluminum plate. Since aluminum and copper are both materials with good thermal conductivity, this can improve the conduction of cold energy.

[0043] Please see Figure 1 and Figure 2 A sealing ring is provided at the connection between the base plate 31 and the transmission plate, and the sealing ring is located circumferentially on the cooling plate 30. The sealing ring can effectively improve the sealing performance of the accommodating cavity 33 and the connecting channel 34, which helps to accelerate the air cooling speed.

[0044] Please see Figure 1 and Figure 2 The condenser tube 40 is fixedly installed inside the accommodating cavity 33, and the upper end of the condenser tube 40 abuts against the conductive plate 32. The condenser tube 40 is provided with a water inlet and a water outlet, and the water inlet and the water outlet are connected to an external cooling water circulator through a conduit.

[0045] Please see Figure 3 The movable plate 50 has a conductive strip 51 at its bottom, which abuts against the conductive plate 32. The conductive strip 51 allows for rapid transfer of cold energy to the movable plate 50 and also allows some of the cold energy to further cool the air in the conductive channel 53, improving the utilization rate of cold energy. The movable plate 50 has a positioning groove 52 at its bottom that matches the positioning post 36. A conductive channel 53 is provided inside the movable plate 50, and the positioning groove 52 communicates with the conductive channel 53. The movable plate 50 has multiple conductive holes 54 at its top, which communicate with the conductive channel 53. These multiple conductive holes 54 are arranged in an array on the movable plate 50. A fixing plate 80 for fixing the EVA workpiece is provided on the movable plate 50. Cooling holes 81 are provided inside the fixing plate 80, and each cooling hole 81 corresponds to one of the conductive holes 54.

[0046] Please see Figure 1 The EVA hot and cold setting device 100 also includes a guide rod 60, one end of which is fixedly connected to the frame 10, and the other end of which passes through the movable plate 50 and is fixedly connected to the cooling plate 30.

[0047] Please see Figure 1 The EVA hot and cold setting device 100 also includes a pad 70, and the cooling plate 30 is fixedly connected to the frame 10 through the pad 70.

[0048] The working principle of the EVA hot and cold setting device 100 in this embodiment is as follows: During hot pressing, the operator places the EVA workpiece above the movable plate 50, and the driver drives the movable plate 50 to press against the hot pressing plate 20 to achieve the hot setting function; after hot pressing is completed, the driver drives the movable plate 50 to move downward and abut against the cooling plate 30; air enters the accommodating cavity 33 through the air inlet pipe 37 and is frozen by the condenser pipe 40. The frozen air enters the conduction channel 53 through the air outlet 38. The frozen air directly cools the EVA workpiece through the conduction hole 54 and the cooling hole 81. At the same time, part of the cooling capacity of the condenser pipe 40 is transferred to the fixed plate 80 through the conduction plate 32, the conduction strip 51 and the movable plate 50 to cool the EVA workpiece. This is to cool and set the newly formed EVA workpiece without the need for the operator to perform cooling conversion.

[0049] The beneficial effects of this utility model are as follows: the air is frozen by the condenser tube 40, and the frozen air is directly cooled on the EVA workpiece through the air outlet 38, the conduction channel 53 and the conduction hole 54. At the same time, part of the cold energy of the condenser tube 40 is cooled on the EVA workpiece through the cooling plate 30 and the movable plate 50. There is no need for the operator to perform the cooling conversion. The cooling effect is good, the cooling time is shortened and the production efficiency is improved.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
