[0003] At present, the existing wax pressing machine has some disadvantages in actual use, such as:

[0004] 1. The existing wax melting pot of the wax pressing machine lacks a mechanism for preheating the solid wax, which results in the overall temperature of the wax liquid in the wax melting pot being easily reduced when the solid wax at room temperature is added, thus breaking its constant temperature state;

[0005] 2. The wax melting pot of the existing wax press lacks a mechanism for cleaning the pot wall and the wax outlet nozzle, which causes the wax liquid remaining in the wax melting pot to easily solidify and be adsorbed on the pot wall and the wax outlet nozzle when the wax press stops operating, which easily blocks the wax outlet nozzle and affects the subsequent normal operation of the equipment. In view of this, the utility model proposes a constant temperature control device for a wax press. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] According to the attached Figure 1-4 As shown, an embodiment of the utility model provides a constant temperature control device for a wax press, comprising a wax melting cylinder 1, a conical temperature conducting plate 2 is arranged inside the wax melting cylinder 1, a lifting mechanism for driving the conical temperature conducting plate 2 to move up and down is arranged on the inner top wall of the wax melting cylinder 1, a feed port 3 and a wax outlet nozzle 4 are respectively arranged on the upper surface and the lower surface of the wax melting cylinder 1, a heating component 5 is embedded in the inner bottom wall of the wax melting cylinder 1, and a temperature conducting rod 6 is fixedly connected to the lower surface of the conical temperature conducting plate 2.

[0026] The inner bottom wall of the conical temperature conducting plate 2 is provided with a conical guide protrusion 7, and the inner bottom wall of the conical temperature conducting plate 2 is penetrated by four wax outlet holes 8 in a circular array and adjacent to the conical guide protrusion 7. Through the setting of the conical guide protrusion 7, the solid wax preheated in the conical temperature conducting plate 2 can flow out smoothly and accurately through the wax outlet holes 8.

[0027] The conical temperature conducting plate 2 and the temperature conducting rod 6 are both made of heat conducting copper material. Through the arrangement of the conical temperature conducting plate 2 and the temperature conducting rod 6, the wax liquid 16 in the wax melting cylinder 1 can be heat-conducted to make the conical temperature conducting plate 2 hot. After being heated, the conical temperature conducting plate 2 can preheat the solid wax therein.

[0028] The lifting mechanism includes a mounting cylinder 9 embedded in the top wall of the wax melting cylinder 1, and a motor 10 is fixedly installed on the upper end of the mounting cylinder 9. The output shaft of the motor 10 extends to the interior of the mounting cylinder 9 and is fixedly connected to a threaded rod 11. The surface of the threaded rod 11 is threadedly connected to a threaded cylinder 12, and the lower end of the threaded cylinder 12 is fixedly connected to the upper surface of the conical temperature conducting plate 2.

[0029] Guide slide blocks are provided on both side surfaces of the threaded cylinder 12, and guide grooves for the guide slide blocks to slide are provided on both side inner walls of the mounting cylinder 9. Under the guidance of the guide slide blocks, the threaded cylinder 12 can drive the conical temperature conducting plate 2 to move up and down through the rotation of the threaded rod 11.

[0030] The rod diameter of the temperature conducting rod 6 is adapted to the channel of the wax outlet nozzle 4, and the lower surface of the conical temperature conducting disk 2 is provided with a scraping edge 13, and the scraping edge 13 overlaps the inner wall of the wax melting cylinder 1. Through the setting of the temperature conducting rod 6 and the scraping edge 13, when the threaded cylinder 12 drives the conical temperature conducting disk 2 to move downward, the channel of the wax outlet nozzle 4 and the inner wall of the wax melting cylinder 1 can be scraped by the temperature conducting rod 6 and the scraping edge 13 respectively.

[0031] A temperature sensor 14 is provided on the left surface of the wax melting cylinder 1, and the detection end of the temperature sensor 14 extends to the inside of the wax melting cylinder 1.

Through the setting of the temperature sensor 14, the temperature inside the wax melting cylinder 1 can be monitored.

[0032] When the wax pressing machine constant temperature control device of the utility model is in use, the temperature in the wax melting cylinder 1 can be monitored under the action of the temperature sensor 14. When the temperature in the wax melting cylinder 1 is too low, the temperature sensor 14 starts the heating component 5 to heat up through the controller 15, and vice versa, the temperature is lowered, so that the wax pressing machine can achieve the effect of controlling the constant temperature state. When the solid wax needs to be fed, the solid wax is put into the conical temperature conducting plate 2 through the feed port 3. Under the action of the temperature conducting rod 6, the high temperature of the wax liquid 16 can be transmitted to make the conical temperature conducting plate 2 hot, and the conical temperature conducting plate 2 After becoming hot, the solid wax inside it can be preheated. When the wax press is used up, the motor 10 drives the threaded rod 11 to rotate, and the threaded cylinder 12 drives the conical temperature conducting plate 2 to move downward under the rotation of the threaded rod 11. The downward movement of the conical temperature conducting plate 2 drives the scraping edge 13 and the temperature conducting rod 6 to scrape the inner wall of the wax melting cylinder 1 and the channel of the wax outlet nozzle 4 to remove the adsorbed residual wax liquid 16. At the same time, the conical temperature conducting plate 2 drives the temperature conducting rod 6 to move downward and insert into the channel of the wax outlet nozzle 4 to play a blocking role, so as to control the wax outlet operation of the wax outlet nozzle 4.
