Technical Field
The utility model relates to a die mould technical field especially relates to a die mould lower die structure with drainage structures.
Background
When the die-casting mold is used for producing the box body type structure, a gas shrinkage hole may exist inside the cylinder body structure, and the gas shrinkage hole is formed for various reasons, such as: insufficient exhaust; water marks exist during the production of the mould; accumulated heat accumulation cannot be discharged, and the like, when the cavity structure is not changed, in order to solve the problem of shrinkage cavity, the quality of the cylinder body is improved by modifying the die structure, which is very necessary.
Disclosure of Invention
The utility model aims to solve the technical problem that a die mould lower die structure with drainage structures is provided, have the drying rate that improves the die surface thereby improve production efficiency, improve exhaust efficiency, avoid characteristics such as product inside shrinkage cavity that appear.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a die mould lower die structure with drainage structures, including lower die frame, lower mold core and the piece of loosing core, lower die frame up end middle part embedding install down the mold core, the die cavity has been arranged at lower mold core up end middle part, lower mold core left and right sides mid-mounting have the take-up housing of die frame under the embedding, the take-up housing is close to one of lower mold core and serves and install the piece of loosing core that stretches into the die cavity, take-up housing around the side all install the layering that links to each other with lower die frame, be located the rear side of the layering of take-up housing front side, and be close to one of lower mold core and serve and arrange the water drainage tank, the lower die frame of water drainage tank below on arranged.
The front part of the upper end surface of the lower die frame is provided with a pouring gate structure, the rear side of the pouring gate structure is provided with a cavity block covering the left front part of the cavity, and the lower end of the pouring gate structure extends to the lower side of the cavity block and is in butt joint with the cavity.
Exhaust runners are uniformly arranged on the rear sides of the two ends of the die cavity, extend to the lower side of the core-pulling block and then extend towards the rear side of the lower die core, and are communicated with an exhaust block component positioned on the rear side of the lower die core.
And a plurality of exhaust slag ladles are arranged on the lower mold core at the left rear side of the mold cavity.
Has the advantages that: the utility model relates to a die mould lower die structure with drainage structures, its concrete advantage as follows:
(1) the drainage grooves and the drainage holes which are matched with the sliding block seats are designed on the pressing strips, so that water stains on the surface are prevented from being accumulated at the position in the production process of the mold, the drying condition of the surface of the mold is ensured, and the product is prevented from having a shrinkage cavity;
(2) by designing the cavity block, the molding of the front part of the cylinder body is facilitated, and meanwhile, the sprue structure can smoothly dredge aluminum liquid;
(3) through arranging the exhaust flow channel, the heat accumulation at the complex positions at the two ends of the cylinder body is brought out while the internal gas is exhausted conveniently, and the product quality is ensured.
Drawings
Fig. 1 is a top view of the present invention;
fig. 2 is a cross-sectional view of the drain groove of the present invention.
The figure is as follows: 1. the core-pulling device comprises a lower die frame, 2, a lower die core, 3, a sliding block seat, 4, a core-pulling block, 5, a pressing strip, 6, a water drainage groove, 7, a water drainage hole, 8, a pouring gate structure, 9, a die cavity, 10, a die cavity block, 11, an exhaust runner, 12, an exhaust block assembly, 13 and an exhaust slag ladle.
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 die mould lower die structure with drainage structures, as shown in fig. 1-2, including lower framed 1, lower mold core 2 and loose core piece 4, lower framed 1 up end middle part embedding install lower mold core 2, die cavity 9 has been arranged at lower mold core 2 up end middle part, 2 left and right sides mid-mounting of lower mold core have the slider seat 3 of framed 1 under the embedding, slider seat 3 is close to one of lower mold core 2 and serves and install the piece 4 of loosing core that stretches into die cavity 9, slider seat 3 front and back side all install the layering 5 that links to each other with lower framed 1, be located the rear side of layering 5 of slider seat 3 front side, and be close to one of lower mold core 2 and serve and arrange drainage channel 6, drainage channel 6 below lower framed 1 on arranged wash port 7.
When the mould carries out product production, because the mould temperature increases along with aluminium liquid injection, the mould intensifies and makes the temperature of surrounding environment also can increase, and product shaping back, need input cooling water to cool off, the mould temperature reduces after the cooling, cooling under high temperature environment, can make the mould surface produce the water mark, need weather the mould surface through auxiliary assembly under the normal conditions, it can cause the product to appear the breathing hole inadequately to weather the degree, and it piles up to produce the water mark most easily between layering 5 and the slider seat 3, in order to avoid this condition, water drainage tank 6 and wash port 7 have been designed, in the mould weathers the in-process, unnecessary water droplet can be followed this position and discharged, when guaranteeing product quality, the production efficiency of mould has also been improved.
And a plurality of exhaust slag ladles 13 are arranged on the lower mold core 2 at the left rear side of the mold cavity 9.
