Description

Technical Field

[0001] The utility model relates to the technical field of wax column machines, in particular to a pressure hammer for wax column machines. Background Art

[0002] The wax column machine is an injection molding equipment used to make wax columns. It generally includes a shell and a wax storage tank, a wax injection cylinder, a wax injection hose, a wax injection port, a hydraulic source, a control circuit and other components arranged on the shell. Driven by the hydraulic source, the softened wax stored in the wax storage tank enters the wax injection cylinder, and then is discharged to the wax injection port through the wax injection hose. Finally, it is injected from the wax injection port into the wax column mold plugged thereon, thereby producing a wax column, that is, a wax column refers to the column of the candle.

[0003] After searching, the Chinese patent application No. 201820380418.3 discloses a fully automatic low-temperature wax injection machine. The utility model discloses a fully automatic low-temperature wax injection machine, including a wax injection machine base, two groups of wax storage cylinders are fixedly installed at symmetrical positions on both sides of the top of the wax injection machine base, the upper end of the wax storage cylinder is fixedly connected to the bottom end of the wax pressing cylinder, a wax inlet pipe is installed on one side wall of the wax pressing cylinder, one end of the wax inlet pipe penetrates through one side wall of the thermostatic box, a wax storage barrel is installed inside the thermostatic box, a temperature controller is inlaid on the front side wall of the thermostatic box, the bottom end of the thermostatic box is fixedly connected to the center of the top of the fixed connecting plate, the top of the fixed connecting plate and the two sides of the thermostatic box are symmetrically installed with a die-forming cylinder, and two groups of hydraulic sliding columns are symmetrically installed on both sides of the bottom end of the fixed connecting plate. The fully automatic low-temperature wax injection machine has a simple structure and reasonable design, is easy to operate, saves time and effort, effectively improves the production efficiency of the wax injection machine, and is conducive to wide promotion and popularization.

[0004] Although the above patented structure is streamlined and reasonably designed, easy to operate, time-saving and labor-saving, and effectively improves the production efficiency of the wax injection machine, in actual use, there is a possibility that the device stops production. At this time, the softened wax retained in the wax spray nozzle in the pressing plate (hammer) is easily solidified into a solid, and causes the wax spray nozzle to be blocked. When the device is started again, the temperature in the constant temperature box needs to be transferred to the wax spray nozzle to melt the solid wax from top to bottom into softened wax. This process is relatively slow, thereby reducing production efficiency.

[0021] refer to Figure 2 The bottom of the protective shell 4 is symmetrically provided with a limiting opening 13 , the top of the inner wall of the telescopic sleeve 12 is symmetrically fixedly connected with a limiting column 14 , and the surface of the top of the limiting column 14 is slidably connected with the limiting opening 13 .
