Graphite crucible static pressure molding machine of removable mold core

Technical Field

The utility model relates to a graphite crucible forming machine, in particular to a graphite crucible mold core can be replaced the static pressure forming machine.

Background Art

The graphite of the crucible for the production machine, the lower die assembly is fixed, in the process of forming the situation of the deformation of the damaged or has the mold core , need to change the whole lower die, causing a lot of waste, and the heavy workload. There is the required different products is not the same as the mould core, of a moulding machine can only cast a product, if it is necessary to produce a variety of types of crucible on the corresponding need for a plurality of types of the lower die. The manufacturers of equipment cost is greatly increased.

Content of the utility model

The purpose of the utility model is directed to the problems existed in the prior art to be improvement and innovation, manufacturers provide can greatly reduce the cost of equipment investment mold core can be replaced of the graphite crucible static pressure forming machine.

The utility model is realized through the following technical scheme:

The graphite crucible mold core can be replaced the static pressure forming machine, characterized in that it includes internal mold, an external mold, combined lower die, support, a hydraulic cylinder, wherein the frame is provided with a hydraulic cylinder, the hydraulic cylinder is connected with the internal mold, the mold is provided with an external mold, the combined is set below the lower die, the lower die by a mold, a mold core, the mold core is provided with the center of the bottom of the of the groove of the internal thread, the mold core is provided with a template, the template is arranged at the center of the projection with the outer thread, which is matched with the groove and the projections.

This utility model has the following advantages:

The utility model adopts the combined lower die, the combined lower die comprises a template, a mould, the mould core and the template movable threaded connection between the, mould can be quickly installed or replaced, can effectively solves the problems of forming machine in the process of forming damage has the mold core , deformation or replace different mould need to change the whole lower die cause a series of problems. Through the design of the utility model, only need to change the mold core, thereby saving time and material saving.

Mode of execution

With reference to the Figure below the utility model for further detailed description.

As shown in Figure 1, a mold core can be replaced 2 graphite crucible static pressure forming machine, which comprises an inner mold 3, the outer 4, combined lower die, bracket 6, the hydraulic cylinder 5. The bracket 6 and the welding the square tube, bracket 6 is provided with the upper part of the hydraulic cylinder 5, the hydraulic cylinder 5 and 3 are connected. The hydraulic cylinder 5 when the up-and-down motion, can drive the inner mould 3 is filled in the upper and lower extrusion die for raw materials of graphite crucible.

Internal mold 3 is provided with an external mold 4, the outer mould 4 is provided with a combined lower die below. The combined lower die comprises a template 1, core 2 form, the mold core 2 is provided with the center of the bottom of the of the groove of the internal thread 7, core 2 is provided with a template 1, the template 1 with an external screw thread is arranged at the center of the lug 8, the projections 8 and grooves 7 phase matching. When the core 2 is damaged, deformed, or need to make different the shape of an inner cavity of the graphite crucible, rapidly changing the core 2, the operation is simple and convenient.

The utility model is only an embodiment of the preferred embodiment of the utility model the description, and not to the limit of the utility model, without deviating from the idea of this utility model is designed on the premise, engineering and technical personnel in this field according to the technical solution of the utility model the various modified and improved, shall include in the utility model the scope of protection.
