The utility model aims to solve the technical problem that a die-casting mold core of car arm lid structure is provided, have simple structure, avoid in just appearing the gas book, improve characteristics such as product quality.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a die-casting mold core of car arm lid structure, includes lower mold core, tip runner cover and die cavity, lower mold core up end middle part be provided with the die cavity, lower mold core up end personally submit the echelonment, and turn right the height by a left side and progressively reduce, the downside of die cavity also corresponding turn right progressively reduce from a left side, tip runner cover be located the left end of lower mold core, be provided with the runner groove in the tip runner cover, be provided with the sprue between runner groove and the die cavity left end.
As a supplement to the technical scheme, the left part of the upper end surface of the lower die core is provided with a first arc-shaped transition part with the right end bent and extended downwards, and the right part of the upper end surface of the lower die core is provided with a second arc-shaped transition part with the right end bent and extended downwards.
As a supplement to the technical scheme, the right end of the lower mold core is provided with a plurality of exhaust blocks side by side.
As a supplement to the technical scheme, the front side and the rear side of the die cavity are provided with first slag ladle structures, and the right side of the die cavity is provided with a second slag ladle structure.
As a supplement to the technical scheme, the middle part of the upper end face of the lower die core is provided with two first hole site forming inserts and a second hole site forming insert from left to right.
Has the advantages that: the utility model relates to a die-casting mold core of car arm lid structure, specific beneficial effect as follows:
(1) the end pouring gate sleeve is arranged, so that the aluminum liquid can directly enter the die cavity, the aluminum liquid directly enters the die cavity through the main runner without a branched structure, the aluminum liquid is quickly filled through the stepped die cavity, hot gas can be smoothly discharged, and the phenomenon of gas entrainment is avoided, so that the product quality is ensured;
(2) through setting up first arc transition portion and second arc transition portion among this technical scheme for aluminium liquid flows to change stably, avoids the aluminium liquid that high pressure was rushed into to take place to strike the phenomenon that splashes, guarantees product quality.
Drawings
Fig. 1 is a top view of the present invention;
fig. 2 is a structural view of the present invention;
fig. 3 is a structural view of the second hole site forming insert of the present invention.
The figure is as follows: 1. the mold comprises a lower mold core, 2, an end sprue bush, 4, a sprue groove, 5, a main runner, 6, a first slag ladle structure, 7, an exhaust block, 8, a mold cavity, 9, a second slag ladle structure, 10, a first arc-shaped transition part, 11, a second arc-shaped transition part, 12, a first hole site molding insert, 13 and a second hole site molding insert.
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-casting mold core of car arm lid structure, as shown in FIG. 1, including lower mold core 1, tip runner cover 2 and die cavity 8, 1 up end middle part of lower mold core be provided with die cavity 8, 1 upper end of lower mold core personally submit the echelonment, and turn right by a left side and highly progressively reduce, the downside of die cavity 8 also corresponding turn right from a left side and progressively reduce, tip runner cover 2 be located the left end of lower mold core 1, be provided with runner groove 4 in the tip runner cover 2, be provided with sprue 5 between runner groove 4 and the 8 left ends of die cavity.
Among this technical scheme, in order to ensure the flow and the pressure of rushing into of aluminium liquid, set up solitary tip runner cover 2 and be used for aluminium liquid to flow into the sprue 5 of die cavity 8, sprue 5 does not possess the bifurcation structure, make aluminium liquid can guarantee to get into die cavity 8 under the condition of inflow pressure, sprue 5 forms solitary material handle structure simultaneously, make things convenient for the workman to take out, improve workman production efficiency, aluminium liquid flows into the back and removes along the ladder terminal surface, make aluminium liquid can be smoothly with steam from the other end discharge of die cavity 1 down, thereby guarantee that the inside gas shrinkage cavity that can not appear of product, ensure product quality.
As a supplement to the present technical solution, the left part of the upper end surface of the lower mold core 1 is provided with a first arc-shaped transition portion 10 with a downward bent and extended right end, and the right part of the upper end surface of the lower mold core 1 is provided with a second arc-shaped transition portion 11 with a downward bent and extended right end.
Through setting up first arc transition portion 10 and second arc transition portion 11 among this technical scheme, under the invariable condition of pressure, the aluminium liquid velocity of flow can keep inconvenient basically to avoid the velocity of flow to increase and form the impact phenomenon, thereby guarantee the quality of product, further avoid appearing the gas book phenomenon.
