Abstract
A water heater magnesium rod foundry die belongs to the technical field of magnesium alloy sacrificial anodes, and the water heater magnesium rod foundry die comprises a die body, wherein an upper plug and a lower plug are fixedly arranged on the die body. The water heater magnesium rod foundry die is characterized in that a threaded hole is manufactured on the upper plug, a screw thread is manufactured on the exposed part of an iron core, the inner diameter of the threaded hole is matched with the outer diameter of the iron core, and the depth of the threaded hole is matched with the length of the exposed part of the iron core. The water heater magnesium rod foundry die guarantees the stability among batches of iron core exposed length, lowers the influence of expansion caused by heat and contraction caused by cold on products in the process of casting magnesium rods, and improves the magnesium rod production pass rate.
Description
Technical field
The utility model belongs to the sacrificial magnesium alloy anode technical field, is specifically related to a kind of water heater magnesium rod casting mould.
Background technology
The sacrificial magnesium alloy anode rod that anticorrosion is used (be called for short magnesium rod) as cathodic protection to the protection bather safety play crucial effects.
In the prior art, the manufacturing process of magnesium rod is: 1) iron core car silk; 2) magnesium melting cast molding; 3) revise polishing; 4) check; 5) packing is dispatched from the factory.Wherein, the most scabrous problem is magnesium zinc location in the cast molding step, and the mould of prior art does not have the iron core positioner, for the client of some positioning requirements strictness, product percent of pass low (about about 40%), a large amount of underproof doing over again cause delay delivery date easily.
Summary of the invention
The purpose of this utility model provides a kind of water heater magnesium rod casting mould, overcomes problems of the prior art, and iron core is accurately located, and improves the qualification rate of product.
The following technical scheme of the concrete employing of the utility model:
A kind of water heater magnesium rod casting mould, comprise die ontology, fixedly install upper and lower two plugs on the die ontology, it is characterized in that, on described upper plug head, be processed with screwed hole, the iron core exposed parts is processed with screw thread, and screwed hole internal diameter and iron core external diameter are complementary, and the screwed hole degree of depth and iron core exposed parts length are complementary.
When the utility model uses, earlier iron core is screwed into upper plug head, guaranteed the iron core protruded length batch between stability, be reduced in the casting magnesium rod motion and expand with heat and contract with cold the influence of product, through applicant's test, adopt the utility model, magnesium rod production qualification rate can reach more than 98%.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Embodiment
As shown in Figure 1, a kind of water heater magnesium rod casting mould comprises die ontology 1, and die ontology 1 is fixed with upper plug head 2 and lower end cap 5, and wherein, the inner surface of upper plug head 2 has screwed hole 4, and the exposed parts of iron core 3 has the screw thread that matches.
Before the magnesium rod casting, iron core 3 is screwed in the screwed hole 4,, the position of iron core between the magnesium rod batch is consistent, improved the excellent qualification rate of casting of magnesium greatly by the length of degree of depth decision iron core 3 exposed parts of screwed hole 4.
