Description

Cantilever type casting machine

Technical Field

The utility model relates to a cantilever type casting machine.

Background

The casting machine is a common device for casting production of chocolate foods at present and mainly comprises a casting head, a supporting frame and a machine table. The pouring head as a core component is generally composed of a pouring shell, a distributing plate, a hopper and a plunger mechanism, wherein the hopper is used for feeding materials into valve cavities at two sides in the pouring shell, the materials enter a plunger cavity communicated with the valve cavities through control of the valve cores, then the materials are extruded onto the distributing plate at the lower part of the valve cavities under the pushing and extrusion of the plunger mechanism and flow into a receiving groove corresponding to the valve cavities on the distributing plate, and finally the materials flow out of a pouring pipe at the bottom of the distributing plate and enter a chocolate template cavity arranged on a machine table to finish pouring.

Of course, the conventional pouring head is generally a single material pouring head, which is only used for pouring and molding pure chocolate products with single slurry, and for the sandwich chocolate of the type on the market at present, because the core material and the shell material adopt different slurries, a special sandwich material pouring head is adopted for pouring and producing. Compared with a conventional single-material pouring head, the sandwich material pouring head adopts a double-hopper design to respectively place core materials and shell materials, and valve cavities at two sides in corresponding pouring shells and corresponding plunger mechanisms also respectively act on extrusion pushing of the core materials and the shell materials. Core materials and shell materials extruded by corresponding valve cavities above are respectively collected on a distributing plate at the bottom of the pouring shell through a core trough and a shell trough, and the core trough and the shell trough are communicated with an inner pouring channel and an outer pouring channel of a double-layer pouring pipe at the bottom of the distributing plate. At the final casting, the core and shell materials are extruded from the double-layer casting tube into the cavity (e.g., split spherical cavity) of the chocolate template to complete the casting of the filled chocolate product.

For the stability of casting, the existing casting head is usually completely fixed on the machine by adopting a supporting frame, and can not be lifted, so that the following problems are brought in actual production:

1. Whether it is a single or sandwich pour head, it is often necessary to extend the pour tube into the cavity to effect pouring in order to avoid the risk of spillage when the cavity of the chocolate mould plate is not aligned with the corresponding pour tube above. In particular, for a type of split closed cavity (e.g., a spherical cavity) of a pouring sandwich material, only one pouring hole is usually reserved at the top, and the split closed cavity is difficult to align with an upper pouring tube, so that the pouring tube can be directly inserted into the pouring hole for pouring in actual operation.

However, as the height of the pouring head cannot be adjusted in a lifting manner, in order to ensure that the pouring pipe can extend into the cavity or the pouring hole, two methods can only be adopted at present, one method is to replace a thicker distributing plate so as to adapt to the height of the chocolate template below; the other is to raise the chocolate template below to accommodate the height of the upper dispensing plate. In any mode, the operation steps are greatly increased, so that the actual production process becomes very complicated, the workload of workers is increased, and the production efficiency is reduced; and the distribution plates and chocolate templates with various specifications are required to be additionally arranged, so that the equipment investment cost of enterprises is obviously greatly increased.

2. For the filling material pouring head, when the filling material is poured by the filling material pouring head at present, when the pouring pipe stretches into the pouring hole to perform pouring, the process of gradually lifting the pouring pipe upwards is needed at the end, so that the top shell material can flow out in an accelerating way to finish closing the core material, and the final forming effect of the filled chocolate product is improved. However, since the casting head is fixed and is not movable in a lifting manner, the lifting operation cannot be completed by the conventional casting machine. For this purpose, it is common practice in the industry to perform this action by experienced workers holding the underlying chocolate template gradually downwards. However, since the downward movement is performed at a constant speed and slowly, the worker must keep his attention for a long time, and thus, the worker is extremely fatigued, and is often required to be interrupted, and it is basically difficult to continuously perform the casting production.
