Description

Technical Field

[0001] This utility model relates to the field of lost foam casting technology, specifically to a lost foam casting device for pipe fittings. Background Technology

[0002] Lost foam casting is an advanced precision casting process. Its core principle is to use a foam plastic model instead of a traditional wax model or wooden model. During pouring, the model vaporizes and disappears, and the molten metal fills the cavity to form a casting.

[0003] In existing technology, when casting lost foam pipe fittings, the corresponding lost foam is usually placed in a mold box, filled with casting sand, and a pouring port is reserved. The pouring funnel is then placed at the pouring port for pouring. To prevent molten metal from leaking out, the operator needs to move the bucket containing molten metal close to the funnel during pouring, aligning the outlet of the bucket with the funnel. However, the funnel is usually directly inserted at the pouring port without any fixing measures. This can easily cause the funnel to tilt or shift if the bucket outlet accidentally touches the funnel during operation, affecting the pouring operation. Therefore, a lost foam pipe fitting pouring device is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a lost foam casting device for pipe fittings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lost foam casting device for pipe fittings, comprising a lost foam outer box; a U-shaped frame is detachably installed on the lost foam outer box, a positioning support structure is connected to the U-shaped frame, T-shaped strips are installed on both sides of the lost foam outer box, an installation structure is connected between the two T-shaped strips and the U-shaped frame, and an adjustment structure is connected inside the U-shaped frame.

[0006] Preferably, the positioning support structure includes a slide block, which is slidably mounted on a U-shaped frame, and a casting funnel is installed inside the slide block.

[0007] Preferably, the slide block has a horizontal groove inside, the U-shaped frame is slidably installed in the horizontal groove, and a positioning screw is installed inside the slide block, with one end of the positioning screw pressing against the surface of the U-shaped frame.

[0008] Preferably, the mounting structure includes a limiting sleeve, which is slidably mounted inside the U-shaped frame and on the T-shaped strip.

[0009] Preferably, the limiting sleeve has a T-groove inside, the T-strip is slidably installed in the T-groove, and a positioning screw is installed inside the limiting sleeve with a thread, one end of the positioning screw being pressed against the surface of the U-shaped frame.

[0010] Preferably, the adjustment structure includes an adjustment screw, which is rotatably mounted inside the U-shaped frame and threadedly mounted inside the limiting sleeve.

[0011] Preferably, the inner walls on both sides of the U-shaped frame are provided with vertical sliding grooves, and guide sliders are slidably installed in both vertical sliding grooves. The two guide sliders are respectively installed on both sides of the limiting sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) In use, the limiting sleeve can be fitted onto the T-shaped strip to support the U-shaped frame. Pushing the limiting sleeve can adjust the position of the U-shaped frame. Pushing the slide block can drive the pouring funnel to slide along the U-shaped frame to adjust its position, ensuring that the pouring funnel is aligned with the pouring port. Then, rotating the adjusting screw can control the U-shaped frame and the pouring funnel to descend, so that the outlet of the pouring funnel can descend to the pouring port for pouring. The U-shaped frame and the limiting sleeve can provide support for the installation of the pouring funnel, improve the stability of the pouring funnel, and thus avoid accidental contact with the pouring funnel during pouring, which would cause the pouring funnel to tilt or shift, thus ensuring the normal operation of the lost foam casting process.

[0014] (2) The limiting sleeve and the T-strip adopt a detachable design. By removing the limiting sleeve from the T-strip, the pouring funnel can be easily removed so that it can be installed on different lost foam outer boxes for use, while avoiding interference when demolding the pipe fittings.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a lost foam casting device for pipe fittings, including a lost foam outer box 100; a U-shaped frame 200 is detachably installed on the lost foam outer box 100, a positioning support structure is connected to the U-shaped frame 200, T-shaped strips 300 are installed on both sides of the lost foam outer box 100, an installation structure is connected between the two T-shaped strips 300 and the U-shaped frame 200, and an adjustment structure is connected inside the U-shaped frame 200.

[0022] Furthermore, the positioning support structure includes a slide 201, which is slidably mounted on the U-shaped frame 200. A pouring funnel 202 is installed inside the slide 201, and the slide 201 can slide on the U-shaped frame 200 to adjust the position of the pouring funnel 202.

[0023] Furthermore, a horizontal groove 203 is provided inside the slide block 201, and the U-shaped frame 200 is slidably installed in the horizontal groove 203. A positioning screw 204 is threaded inside the slide block 201. One end of the positioning screw 204 is pressed against the surface of the U-shaped frame 200. Pushing the slide block 201 allows it to slide on the U-shaped frame 200 through the horizontal groove 203, thereby moving the pouring funnel 202 to directly above the pouring port. After adjustment, rotating the positioning screw 204 will press it against the surface of the U-shaped frame 200, thereby restricting the installation position of the pouring funnel 202.

[0024] Furthermore, the installation structure includes a limiting sleeve 301, which is slidably installed inside the U-shaped frame 200 and on the T-shaped strip 300. During installation, the limiting sleeve 301 can be fitted onto the T-shaped strip 300 to install the U-shaped frame 200.

[0025] Furthermore, the limiting sleeve 301 has a T-slot 302 inside, and the T-strip 300 is slidably installed in the T-slot 302. The limiting sleeve 301 has a positioning screw 303 inside, and one end of the positioning screw 303 is pressed against the surface of the U-shaped frame 200. The limiting sleeve 301 can move on the T-strip 300 through the T-slot 302 to adjust the position of the pouring funnel 202. By rotating the positioning screws 303 on both sides, they can be pressed against the surface of the T-strip 300, thereby fixing the installation position of the U-shaped frame 200.

[0026] Example 2: As Figure 1-3 To facilitate adjustment of the height of the pouring funnel 202 according to the height of the pouring gate, an adjustment structure is provided. The adjustment structure includes an adjustment screw 400, which is rotatably installed inside the U-shaped frame 200. The adjustment screw 400 is threadedly installed inside the limiting sleeve 301. Vertical grooves 401 are provided on both inner walls of the U-shaped frame 200. Guide sliders 402 are slidably installed in both vertical grooves 401. The two guide sliders 402 are respectively installed on both sides of the limiting sleeve 301. Rotating the adjustment screws 400 on both sides allows them to move through the threaded engagement with the limiting sleeves 301, thereby driving the U-shaped frame 200 to move up and down. When the U-shaped frame 200 moves up and down, it can slide on the guide sliders 402 through the limiting sleeves 301. By controlling the descent of the U-shaped frame 200, the discharge port of the pouring funnel 202 can be driven down to the pouring gate. The remaining features are the same as in Embodiment 1.

[0027] The working principle is as follows: After placing the lost foam casting fittings inside the lost foam outer box 100 and filling it with casting sand, the outlet of the pouring funnel 202 can be installed at the pouring gate. During installation, the limiting sleeve 301 can be fitted onto the T-strip 300 through the T-slot 302. By pushing the limiting sleeve 301, the positions of the U-shaped frame 200 and the pouring funnel 202 on the lost foam outer box 100 can be adjusted. When the pouring funnel 202 corresponds to the pouring gate, the fixed sides can be rotated... Positioning screw 303, when rotated, can move through the threaded engagement with limiting sleeve 301, causing the moving positioning screw 303 to press against the surface of T-shaped strip 300, thereby fixing the installation position of U-shaped frame 200. Then, pushing slide block 201 allows it to slide on U-shaped frame 200 through horizontal slide groove 203, thereby moving pouring funnel 202 directly above the pouring gate, ensuring accurate alignment. After adjustment... The rotating positioning screw 204 can move by engaging with the slide 201 through a threaded connection, allowing it to press against the surface of the U-shaped frame 200, thereby restricting the installation position of the slide 201 and the casting funnel 202. Finally, the adjusting screws 400 on both sides are rotated. When the adjusting screws 400 rotate, they will rotate within the U-shaped frame 200 and can move by engaging with the limiting sleeve 301 through a threaded connection. This allows the adjusting screw 400 to drive the U-shaped frame 200 to move up and down. When the U-shaped frame 200 moves up and down, it can slide on the guide slider 402 through the limiting sleeve 301, thereby limiting the direction of movement of the U-shaped frame 200 on the limiting sleeve 301. By controlling the descent of the U-shaped frame 200, the outlet of the pouring funnel 202 can be driven down to the pouring port to ensure that it can be aligned. The support setting of the U-shaped frame 200 can prevent the position of the pouring funnel 202 from shifting during pouring.
