Abstract
The utility model discloses a liquid die forging die, which comprises an upper die, a base, a core rod and a flange sleeve, wherein the inner surface of the flange sleeve is embedded with a right die and a left die which are matched for use, the inner sides of the right die and the left die form a product die cavity, the core rod is arranged at the center of the product die cavity, and the upper die and the base are sequentially arranged at the top and the bottom of the flange sleeve; the utility model discloses a flange cover and plug effect can be favourable mould cooling, reduce the drawing of patterns resistance, provide product production efficiency, because the gradient of flange cover internal surface makes the continuous close of right mould and left mould tight at the in-process of fastening for the product appearance in the die cavity does not have the gradient.
Description
Technical Field
The utility model relates to a pump body product mould equipment technical field specifically is a liquid mold forging mould.
Background
The hydraulic gear pump body casting is used as an important component of the hydraulic three-component, and the performance requirement of the casting is high due to the fact that the casting bears large pressure and impact in working engineering. The traditional pump body is generally formed by adopting a gravity casting process, the utilization rate of casting materials is low, the machining allowance is large, and the product performance is general. The liquid die forging process enables the casting to be formed under isostatic pressure, the comprehensive performance of the casting is obviously improved, and particularly, the direct liquid die forging process is adopted, pressure directly acts on the casting, and the influence of pressure loss on the performance of the casting is reduced. The direct liquid forging generally adopts an upper and lower die closing structure, and in order to reduce the demoulding resistance, the lower die needs to be designed with the draft angle. However, the hydraulic gear pump body is large in height and size, the design draft gradient can seriously affect the size requirement of a casting, the processing difficulty is increased, and the material utilization rate is reduced.
SUMMERY OF THE UTILITY MODEL
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a liquid mould forging die, includes mould, base and plug, still includes the flange cover, and the internal surface of flange cover inlays and is equipped with right mould and left mould that the cooperation was used, and right mould and left mould inboard form a product die cavity, and the plug sets up the position at product die cavity center, goes up mould, the position of the top of flange cover and bottom is located in proper order branch to the base, and the flange cover passes through the bolt fastening on the base, and the flange cover can be favorable to the mould cooling with the plug effect, reduces drawing of patterns resistance, provides product production efficiency.
Furthermore, the inner surface of the cross section of the flange sleeve is trapezoidal, the outer surfaces of the right die and the left die are matched with the inner surface of the flange sleeve, and when the flange sleeve and the base are fixed, the right die and the left die are continuously tightly closed due to the gradient of the inner surface of the flange sleeve in the fastening process, so that the appearance of a product in the die cavity has no gradient.
Furthermore, a through hole channel is formed in the middle of the core rod, and the through hole structure arranged in the middle enables the core rod to be cooled more easily through cooling the through hole channel after a product is formed, so that the demoulding resistance is reduced.
The working principle and the beneficial effects are as follows: the flange sleeve and the core rod can be used for facilitating mold cooling, reducing demolding resistance and improving product production efficiency, and due to the gradient of the inner surface of the flange sleeve, the right mold and the left mold are continuously closed tightly in the fastening process, so that the appearance of a product in the mold cavity has no gradient.
Drawings
FIG. 1 is a schematic perspective view of the present invention;
FIG. 2 is a schematic structural view of the cross section A-A of FIG. 1 according to the present invention;
fig. 3 is a schematic view of the three-dimensional structure of the present invention.
In the figure: 1. a flange sleeve; 2. a right die; 3. a left die; 4. a product mold cavity; 5. a core rod; 6. an upper die; 7. a base.
Detailed Description
The invention will be better understood from the following examples.
The drawings in the specification show the structure, ratio, size, etc. only for the purpose of matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and not for the purpose of limiting the present invention, so the present invention does not have the essential meaning in the art, and any structure modification, ratio relationship change or size adjustment should still fall within the scope covered by the technical content disclosed in the present invention without affecting the function and achievable purpose of the present invention. Meanwhile, the terms "upper", "lower", "front", "rear", "middle", and the like used in the present specification are for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.
As shown in fig. 1-3, a liquid die forging die comprises an upper die 6, a base 7, a mandrel 5 and a flange sleeve 1, wherein a right die 2 and a left die 3 which are matched with each other are embedded in the inner surface of the flange sleeve 1, a product die cavity 4 is formed inside the right die 2 and the left die 3, the mandrel 5 is arranged at the center of the product die cavity 4, the upper die 6 and the base 7 are sequentially arranged at the top and the bottom of the flange sleeve 1, the flange sleeve 1 is fixed on the base 7 through bolts, and the flange sleeve and the mandrel have the effects of facilitating die cooling, reducing demolding resistance and improving the production efficiency of products.
The inner surface of the cross section of the flange sleeve 1 is trapezoidal, the outer surfaces of the right die 2 and the left die 3 are matched with the inner surface of the flange sleeve, and when the flange sleeve and the base are fixed, the right die and the left die are continuously closed tightly in the fastening process due to the inclination of the inner surface of the flange sleeve, so that the appearance of a product in the die cavity has no inclination.
Wherein, the through-hole passageway has been seted up in the middle of the plug 5, and the through-hole structure that the centre set up is after the product shaping, through cooling through-hole passageway for the plug is changeed the cooling, reduces drawing of patterns resistance.
