Description

Technical Field

[0001] The utility model relates to the technical field of volute processing, in particular to a volute wax model mould with an air release valve. Background Art

[0002] Some existing volutes have related air release valves. Due to the special structure of the volute and the air release valve, they were previously processed and formed using two sets of molds, and then the volute and the air release valve were welded together, resulting in high production costs. The separately formed volute and the air release valve also need to be finely processed later, resulting in low production efficiency. Utility Model Content

[0003] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the utility model provides a wax mold of a volute with an air release valve, which is injection molded by a set of molds at one time.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A volute wax mold with an air release valve comprises an upper mold core and a lower mold core capable of achieving mold closing, an injection cavity is formed between the upper mold core and the lower mold core, gates connected to the injection cavity are respectively provided on the upper mold core and the lower mold core, and multiple sets of profiling core assemblies are also included, the profiling core assemblies comprise a cylinder and a profiling core, the cylinder is fixed to the outer side of the lower mold core, the profiling core is arranged in the injection cavity, the cylinder is connected to the profiling core, the cylinder can drive the profiling core to extend and retract forward and backward, and a volute injection cavity with an air release valve is formed in the gap between each profiling core and the upper mold core and the lower mold core.

[0006] In a preferred embodiment of the present invention, the contour mold core components are three sets, which are respectively arranged on three sides of the lower mold core.

[0007] In order to facilitate the driving of the profiling mold core to move, the profiling mold core assembly also includes a guide seat, one end of which is detachably connected to the lower mold core, and the other end extends outside the lower mold core. A guide block is slidably connected inside the guide seat, and the profiling mold core is fixed to the guide block. The cylinder can drive the guide block to move forward and backward along the guide seat.

[0008] In order to prevent the guide block from shaking slightly, the contour core assembly also includes a pressing block, which is fixed to the bottom end of the upper mold core. The guide block is provided with a slot for the pressing block to be inserted from top to bottom.

[0009] The utility model is beneficial in that the wax mold of the volute with an air release valve cooperates with the upper mold core and the lower mold core through various contour core components, so that the volute with an air release valve can be injection molded in one step without subsequent finishing, which greatly reduces production costs, improves production efficiency, and ensures product quality.
