Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses an improve water axle sleeve casting mould of watering, including cover half 1 and movable mould 2, cover half 1 is equipped with runner 11, is equipped with between cover half 1, movable mould 2 with runner 11 intercommunication water 3, be used for the die cavity 4 of shaping product 7. The pouring gate 3 and the cavity 4 are formed by combining wall surfaces of the fixed die 1 and the movable die 2 which are opposite to each other, the top walls of the pouring gate 3 and the cavity 4 are formed on the bottom surface of the fixed die 1, and the bottom walls of the pouring gate 3 and the cavity 4 are formed on the top surface of the movable die 2.

The pouring gate 3 comprises a filling channel 31, a first inclined chute 32 and a second inclined chute 33, wherein the filling channel 31 is concave downwards towards the movable die 2, and the filling channel 31 is positioned in the middle of the pouring gate 3. The first inclined channel 32 and the second inclined channel 33 are respectively positioned at two ends of the filling channel 31, wherein the second inclined channel 33 is positioned at the end part of the filling channel 31, which is away from the cavity 4, and the second inclined channel 33 communicates the filling channel 31 and the cavity 4; a first chute 32 is located at the end of the filling channel 31 facing away from the mould cavity 4. The inclination of the first chute 32 is greater than that of the second chute 33, namely, the inclination degree of the length direction of the first chute 32 relative to the length direction of the filling channel 31 is greater than that of the length direction of the second chute 33 relative to the length direction of the filling channel 31.

The first inclined channel 32 plays a role in guiding the flow, and the first inclined channel 32 with a larger inclination can play a role in blocking the metal from entering the filling channel 31, so that the flow rate of the metal entering the filling channel 31 is reduced. The filling channel 31 is used for temporarily storing the metal liquid, and the metal in the filling channel 31 overflows into the cavity 4 after being nearly filled. By arranging the filling channel 31, the metal entering the cavity 4 can be completed in a short time; the second chute 33, which has a smaller slope, has less resistance to the entry of metal into the mould cavity 4.

The pouring gate 3 is communicated with the cavity 4 through an extrusion casting port 41 arranged between the pouring gate and the cavity 4, the extrusion casting port 41 is specifically formed between the second inclined channel 33 and the cavity 4, and the height of the extrusion casting port 41 is 2-3 mm.

The heat preservation cavity 35 of the embodiment is curved in an arc shape towards the cavity 4, and the heat preservation cavity 35 is preset with a larger volume; after the liquid metal enters the runner 3, the metal further enters the insulated chamber 35 to be filled. After the heat preservation cavity 35 is filled with liquid metal, the heat of the heat preservation cavity 35 can be transferred to the cavity 4, and the temperature of the molten metal is higher; the liquid metal does not immediately cool and solidify after it enters the cavity 4. The arrangement enables each part of the product 7 in the cavity 4 to be cooled at the same speed, and improves the forming quality of the product 7. At the same time, the heat of the holding chamber 35 ensures that the metal does not solidify directly at the narrower squeeze casting mouth 41.

Referring to fig. 2 and 4, the product 7 of the present embodiment has a through hole 71, and the through hole 71 penetrates through the product 7 in the mold opening direction of the fixed mold 1 and the movable mold 2. The movable die 2 is internally provided with a molding rod 21 for molding a through hole 71 of a product 7, the molding rod 21 protrudes into the cavity 4, and the length direction of the molding rod 21 is along the die opening direction of the movable die 2 and the fixed die 1.

Referring to fig. 1 and 2, a plurality of ejector rods 22 for demolding are arranged in the movable mold 2, the ejector rods 22 can extend out of the movable mold 2 through movement to eject a casting, and the bottom wall of the pouring gate 3 is correspondingly provided with the ejector rods 22. The ejector 22 is driven by a demoulding mechanism built in the moving die 2, the demoulding mechanism comprises an oil cylinder, and the demoulding mechanism is the prior art and is not described herein. Still be equipped with a plurality of supplementary chambeies 5 between cover half 1, movable mould 2, supplementary chamber 5 is circumference distribution outside die cavity 4, and supplementary chamber 5 communicates through the connector 51 of locating between the two with die cavity 4, and the chamber bottom correspondence of supplementary chamber 5 is equipped with ejector pin 22. The height of the connecting opening 51 is close to that of the extrusion casting opening 41, so that a person can knock with a hammer to break the metal formed at the connecting opening 51, and the product 7 is separated from the waste formed in the auxiliary cavity 5.

Limited to the elongated shape of some products 7, and the possible presence of through holes 71 in the products 7, the bottom of some products 7 is not positioned with ejector pins 22 for ejecting them. Through setting up supplementary chamber 5, form the structure of integrative fixed with product 7 after the metal cooling in supplementary chamber 5, after ejector pin 22 is ejecting the fashioned metal block in supplementary chamber 5, this metal block can break away from movable mould 2 with product 7 together.

As shown in fig. 4 and 5, the shape of the casting formed by the casting mold completely corresponds to the shape of the cavity such as the runner 3 and the cavity 4 after combination. The casting comprises a product 7 and waste, wherein the pouring gate 3 forms a main pouring section 6, the extrusion casting port 41 forms an extrusion casting section 61, the die cavity 4 forms the product 7, the connecting port 51 forms a connecting section 62, and the auxiliary cavity 5 forms an auxiliary block 63. The person can break the

segments

61, 62 and separate the product 7 from the scrap.
