Abstract

A wax injector for wax mould maker is composed of a group of straight-direction drive oil cylinders and a group of transverse-direction drive oil cylinders, and features that the straight-direction and transverse-direction displacement drive can be automatically regulated.

Description

The utility model relates to a wax injection device of a wax mold making machine, in particular to a wax injection device installed on a full-automatic wax mold manufacturing machine so that the nozzle can adjust the wax oil injection port according to each mold and automatically correct the injection position.

The fully automatic wax pattern making machine is generally based on three groups of mold adjustment groups that are fixed on a rotating disc in equal parts, and the wax oil is injected separately by staying in the 120° displacement stroke. After cooling and forming, the mold is pulled to make the wax pattern The molding can be completed by continuous process to complete the automatic production work. However, when the general wax pattern making machine cooperates with the molding and manufacturing of three different wax patterns, the shape and size of the film patterns are not consistent, resulting in differences in the position of the wax oil injection port. For adjustment, it must be set one by one according to each mold adjustment group, and the adjustment group of each mold group must be equipped with an independent lifting adjustment mechanism, so there are inevitably complicated defects in the structure, which will increase the cost.

The main purpose of this utility model is to overcome the above-mentioned shortcomings, and propose an improved wax injection device of the wax pattern making machine. The injection nozzle can adjust the wax oil injection port to automatically correct the injection position according to the position of each mold on the wax pattern making machine, making the wax injection device more practical and can simplify the structure comprehensively and facilitate the automatic production of different wax patterns.

The utility model is mainly realized in the following way: the nozzle in the wax injection device is provided with a group of vertically driven hydraulic cylinders and a group of horizontally driven hydraulic cylinders. Automatically adjust the position of the nozzle, so it can adapt to the different sizes and shapes of the wax mold and perform wax injection work, so as to facilitate the more automatic operation and simplify the structure of the wax mold making machine.

Embodiments of the present utility model are described in detail below with reference to the accompanying drawings, wherein:

Fig. 1 is the combined appearance diagram of the utility model coordinating the wax pattern making machine;

Fig. 2 is a combined perspective view of the wax injection device of the present invention;

Fig. 3 is a schematic diagram of the direct drive hydraulic cylinder of the wax injection device of the present invention;

Fig. 4 is a schematic diagram of the lateral drive hydraulic cylinder of the wax injection device of the present invention.

As shown in FIG. 1 , the wax pattern making machine includes: a workbench 1 , a group of control mold closing oil cylinder devices 2 , a transmission mechanism device and a wax injection device 4 . The wax oil is injected at the same time by three sets of mold adjustment groups driving displacement every 120°. Cooling and molding die removal work, and utilize a mechanical arm 5 to engage in the continuous operation process of automatic die removal. The utility model is characterized in that: the wax injection device 4 is mainly composed of a vertically driven hydraulic cylinder 41, a horizontally driven hydraulic cylinder 42 arranged along a slide rail 43, and a nozzle 44, as shown in Figure 2 The vertically driven hydraulic cylinder 41 is set upright on the slide rail 43 by means of two sets of locking seats 45, 46, and the locking seat 46 below it is locked on the nozzle fixing seat 47. The drive to the drive hydraulic cylinder 41 makes the nozzle holder 47 move up and down (as shown in Figure 3), and then the vertical displacement stroke of the nozzle 44 can be set; the horizontal drive hydraulic cylinder 42, cooperate with a locking seat 48 and nozzle fixing seat 47 to be erected horizontally, that is, to use the hydraulic cylinder to drive the nozzle 44 to move forward or backward freely in the fixing seat 47 (as shown in Figure 4), and then can The lateral displacement stroke of the nozzle 44 is set.

Above-mentioned straight drive hydraulic cylinder 41 and horizontal drive hydraulic cylinder 42 are respectively provided with appropriate touch switches 49 at selected places in the vertical or lateral displacement strokes, so that the touch switches 49 can be adjusted to control their displacement strokes. Vertically or laterally drive limit, that is to say, this vertically and laterally drive hydraulic cylinder 41,42 is respectively provided with two touch switches 49 up and down or front and back to control the limit of its stroke. There are technologies, which will not be described separately here.

Utilizing the composition of the wax injection device 4 and setting its circuit control design through automatic adjustment (this circuit design is not included in the characteristics of this case), the injection can be automatically adjusted depending on the position of the wax oil injection port of the three different molds. The injection direction of the nozzle 44 can simplify the structure and facilitate the automatic production of wax patterns with different shapes and sizes.
