Abstract
The utility model belongs to the technical field of a vacuumizing device for a sand box and aims at providing a lost-foam-mold casting sand box with reliable and high-efficiency connection with a negative-pressure pipe. The adopted technical scheme is as follow: the lost-foam-mold casting sand box comprises an auxiliary joint body, a main joint body and a box body, wherein one end of the auxiliary joint body is fixed on a seat opening of the negative-pressure pipe of the box body, and the other end of the auxiliary joint body is sheathed in one end of the main joint body; the other end of the main joint body is sheathed in the negative-pressure pipe and is fixedly clamped by a pipe clamp sheathed outside the negative-pressure pipe; a plurality of fasteners are hinged on the main joint body; one end of each fastener is provided with a pipe clamp clamping hook which is clamped on the pipe clamp, and the other end of each fastener is an auxiliary body clamping block; the auxiliary joint body is provided with a clamping groove matched with the auxiliary body clamping block; a first sealing ring is arranged between the auxiliary joint body and the main joint body; a second sealing ring is arranged between the main joint body and the negative-pressure pipe. The lost-foam-mold casting sand box is mainly used for vacuumizing the sand box in lost-foam-mold casting.
Description
Technical field
The utility model is a kind of to be connected with negative tube reliably, lost foam casting sandbox efficiently, belongs to sandbox vacuum extractor technical field.
Background technology
Existing lost foam casting sandbox and negative tube be connected with two kinds of modes: a kind ofly for negative tube, be directly sleeved on interface, this structure is after negative tube connects, in the process that sandbox moves, negative tube easily comes off, sandbox internal negative pressure value is reduced, and then product rejection, and the gas temperature producing due to the white mould after burning is higher, high-temperature gas enters after negative tube, the easy temperature distortion of negative tube, causes negative pressure not smooth, also can cause product rejection; Another kind of for flange connects, the flange being wherein connected with negative tube is provided with cylinder and promotes, and another is sand box flange, but because two flange faces can not be completely parallel, so contact-making surface easily leaks gas, sandbox internal negative pressure value is reduced, and then product rejection.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is to provide a kind of negative pressure base mouth and negative tube is easy to connect reliable, the lost foam casting sandbox of difficult drop-off.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of connection with negative tube reliably, efficient lost foam casting sandbox, comprise interface daughter, interface parent and casing, one end of interface daughter is fixed on the negative pressure base mouth of casing, the other end of interface daughter is sleeved on the inside of interface parent one end, the other end of interface parent is sleeved on the inside of negative tube and is fixedly clamped by the outer pipe clamp being set with of negative tube, on described interface parent, be hinged with a plurality of buckles, one end of described buckle is provided with pipe clamp grab, described pipe clamp grab is installed on pipe clamp, the other end of buckle is daughter fixture block, described interface daughter is provided with the draw-in groove matching with daughter fixture block.
Between described interface daughter and interface parent, the first sealing ring is installed.
Between described interface parent and negative tube, the second sealing ring is installed.
One end that described buckle is provided with pipe clamp grab is provided with draw ring.
The making material of described interface daughter and interface parent is steel.
Described interface daughter is weldingly fixed on the negative pressure base mouth of casing.
The beneficial effect that the utility model compared with the existing technology had is: the utility model is fixed on interface daughter on the negative pressure base mouth of casing, and be communicated with negative tube by interface parent, when the buckle on interface parent is installed on negative tube pipe clamp, also can hang and link together with interface daughter card, connect reliable, difficult drop-off, finishes using and can also pull draw ring, and itself and the interface daughter being welded on casing are easily departed from; Making material of the present utility model is steel, is not subject to temperatures involved, thereby negative regulation in sandbox, has guaranteed product quality; The sealing ring being arranged between interface daughter, interface parent and negative tube can prevent contact-making surface gas leakage, has guaranteed negative regulation in sandbox, reduces product percent defective.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the mounting structure schematic diagram of interface daughter and interface parent in the utility model.
Fig. 3 is the structural representation of interface daughter in the utility model.
Fig. 4 is the structural representation of interface parent in the utility model.
In figure: 1 is interface daughter, 2 is interface parent, and 3 is the first sealing ring, and 4 is casing, and 5 is negative tube, and 6 is buckle, and 7 is pipe clamp, and 8 is pipe clamp grab, and 9 is daughter fixture block, and 10 is draw-in groove, and 11 is draw ring, and 12 is the second sealing ring.
The specific embodiment
As Figure 1-4, the utility model is a kind of to be connected with negative tube reliably, efficient lost foam casting sandbox, comprise interface daughter 1, interface parent 2 and casing 4, one end of interface daughter 1 is fixed on the negative pressure base mouth of casing 4, the other end of interface daughter 1 is sleeved on the inside of interface parent 2 one end, the other end of interface parent 2 is sleeved on the inside of negative tube 5 and the pipe clamp 7 by negative tube 5 outer suits is fixedly clamped, on described interface parent 2, be hinged with a plurality of buckles 6, one end of described buckle 6 is provided with pipe clamp grab 8, described pipe clamp grab 8 is installed on pipe clamp 7, the other end of buckle 6 is daughter fixture block 9, described interface daughter 1 is provided with the draw-in groove 10 matching with daughter fixture block 9.
The first sealing ring 3 is installed between described interface daughter 1 and interface parent 2.
The second sealing ring 12 is installed between described interface parent 2 and negative tube 5.
One end that described buckle 6 is provided with pipe clamp grab 8 is provided with draw ring 11.
