Description

Connection structure for solving problem of die-casting mold core retreating

Technical Field

The utility model relates to a die mould technical field especially relates to a solve connection structure of die mould core backset.

Background

The die-casting die is a tool for casting metal parts, and is a tool for completing a die-casting process on a special die-casting die forging machine. The basic process of die casting comprises the following steps: molten metal is cast at low speed or high speed and filled into the cavity of the mold, the mold has movable cavity surface, and it is pressurized and forged along with the cooling process of the molten metal, so that the shrinkage cavity and shrinkage porosity defects of the blank are eliminated, and the internal structure of the blank reaches the broken crystal grains in the forged state. The comprehensive mechanical property of the blank is obviously improved.

Common plugs in the existing die casting industry are as follows: the plug is used for preventing the core from retreating by installing one or more sections behind the core, but the effect is not ideal at present. In the production process, the core retreating phenomenon often occurs, so that the corresponding plug connecting structure needs to be optimized.

Disclosure of Invention

The utility model aims to solve the technical problem that a solve connection structure that die mould core moves back is provided, and the second end cap can utilize the elasticity of spring effectively to prevent retreating of first end cap to solved the core and retreated and lead to the problem of product harmfully.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a solve connection structure that die mould core retreated, includes core, mold core and framed, framed in install the mold core, be provided with the core hole in this mold core, the downthehole core, first end cap and the second end cap of installing of core, this core one end passes the mold core, first end cap be located between core and the second end cap, second end cap one end be provided with the guide pillar that inserts in the first end cap, the cover has the spring on this guide pillar.

As a supplement to the technical scheme of the utility model, the spring choose for use belleville spring.

As right the technical scheme of the utility model a supplement, the middle part of guide pillar free end seted up a riveting hole.

As right technical scheme a supplementary, the outside of guide pillar free end arranged the round turn-ups.

Has the advantages that: the utility model relates to a connecting structure for solving the problem of the backward movement of a die-casting mould core, a second plug can effectively prevent a first plug from retreating by utilizing the elasticity of a spring, thereby solving the problem of poor products caused by the backward movement of the core; use the utility model discloses a behind the structure, the phenomenon is retreated to the core that does not appear after long-time production, has improved production efficiency and product percent of pass. The utility model also has the advantages of simple structure, convenient use, low manufacturing cost, etc.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic structural diagram of a first plug according to the present invention;

fig. 3 is a schematic structural view of the second plug of the present invention before being processed;

fig. 4 is a schematic structural view of the second plug and the spring after being processed.

The figure is as follows: 1. the mold comprises a mold core, 2, a first plug, 3, a second plug, 4, a spring, 5, a mold core, 6, a mold frame, 7, a guide pillar, 8, a riveting hole, 9 and a flanging.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

The utility model discloses an embodiment relates to a solve connection structure that die mould core retreated, as shown in fig. 1-4, including core 1, mold core 5 and framed 6, framed 6 in install mold core 5, be provided with the core hole in this mold core 5, the core downthehole core 1, first end cap 2 and the second end cap 3 of installing, mold core 5 is passed to 1 one end of this core, first end cap 2 be located between core 1 and the

second end cap

3, 3 one end of second end cap be provided with the guide pillar 7 that inserts in first end cap 2, the cover has spring 4 on this guide pillar 7, spring 4 select belleville spring for use.

The middle part of the free end of the guide post 7 is provided with a riveting hole 8. And a circle of flanging 9 is arranged on the outer side of the free end of the guide post 7.

From fig. 2 and 3, it can be clearly seen that the first plug 2 and the second plug 3 both have a hexagonal socket in the middle of their lower ends, which is the structure of the existing plugs.

The first plug 2 is a common plug which is commonly used at present, but the second plug 3 is specially made, and the structure before processing is as shown in fig. 3, firstly the spring 4 is sleeved on the guide post 7 of the second plug 3, the riveting hole 8 on the guide post 7 is riveted to form a circle of flanging 9, and the flanging 9 is used for limiting the position of the spring 4. The processed second plug 3 is butted with the first plug 2, the guide pillar 7 is partially inserted into the inner hexagonal hole of the first plug 2, and the spring 4 props against the end face of the first plug 2 and does not extend into the inner hexagonal hole.

During installation, the core 1 is inserted into the core hole, the first plug 2 is loaded to support the core 1, the processed second plug 3 with the spring 4 is loaded finally, the second plug 3 supports the first plug 2, the second plug 3 can effectively prevent the first plug 2 from retreating by utilizing the elasticity of the spring 4, and therefore the problem that the product is poor due to the retreating of the core 1 is solved.
