Problems solved by technology

[0002] In the process of wax mold pressing in precision investment casting, molds of different sizes will be made according to different products. The molds of some larger products are very large in size and quality. In the past, the process of wax mold pressing was made by Manually position and remove the mold. Due to the high quality of the mold, manual positioning and movement are time-consuming and laborious. If the operator makes a mistake and fails to align the wax injection nozzle with the mold injection port, it will cause wax run-off The consequences of this will cause unnecessary losses, and it is time-consuming and laborious to clean up the wax on the workbench, which greatly affects the work efficiency

Embodiment 1

[0025] An ejector device for moving molds on a wax press, such as figure 1 , figure 2 As shown, the manual core pulling device includes a hydraulic cylinder 1, a connecting rod nut 2, a connecting rod 3, a fixed frame 4, a movable frame 5, a top die movable block 6, a limit guide rail 7, a pressure plate assembly 8, and a limiter I9 , limiter II10, limit baffle 11, moving template 12 of wax press machine, fixed template 13 of wax press machine, wherein, the ejector mechanism includes hydraulic cylinder 1, connecting rod nut 2, connecting rod 3, fixed frame 4, can The movable frame 5 and the movable block 6 of the top mold, the fixed frame 4 and the connecting rod 3 are connected by welding, the other side of the connecting rod is connected with the hydraulic cylinder 1 through the nut 2, and the movable frame 5 and the fixed frame 4 are matched. The height of the frame 5 can be adjusted by the tightening bolts to adapt to molds of different heights. The entire ejector mechan...

Embodiment 2

[0027] Such as Figure 4 As shown, the limit guide rail 7 is detachable, and when in use, it is fixed on the fixed template 13 of the wax injection machine by using the pressure plate assembly 8, and the width of the limit guide rail 7 can be adjusted according to the size of the mold. 7 width.

Embodiment 3

[0029] When the ejector device for moving the mold on the wax press machine according to Embodiment 1 or Example 2 of the present invention is used, the hydraulic cylinder is placed on the wax injection nozzle of the wax press machine, and the wax injection nozzle of the wax press machine and the fixed frame 4, can move The frame composed of frame 5 is coaxial, and the signal fed back by the stopper is well combined with the main body of the wax presser. During the mold closing process of the wax presser, when the stopper II on the moving template passes through the limit baffle, the template decelerates. When the stopper II is reached, the wax pattern is pressed. After the wax pattern is pressed, the mold is opened. Before the stopper II, the template is slowly opened. When the stopper II is passed, the template is accelerated to open the mold. At this time, the hydraulic cylinder of the ejection mechanism It will also receive the start signal, and start to move and eject the ...

Abstract

The invention relates to an ejection device for moving a die on a wax injector. The ejection device comprises a limiting device I (9), a limiting device IT (10), a limiting plate (11), a wax injector moving template (12) and a wax injector fixing template (13) and is characterized by also comprising an ejection mechanism hydraulic oil cylinder (1), a connecting rod nut (2), a connecting rod (3), a fixing frame (4), a moving frame (5), die ejection movable blocks (6), guide rails (7) and pressure components (8); and a whole ejection mechanism is driven by the hydraulic oil cylinder (1) to smoothly go in and out. The ejection device is suitable for a wax pattern die with larger volume weight to enable the process of pressing a wax pattern to tend to semi-automation and has the characteristics of a simple structure, convenience in operation, high efficiency and good stability.
