Description

Technical Field

[0001] This utility model belongs to the field of investment casting technology and relates to a silica sol mold shell baking, pouring and inserting device. Background Technology

[0002] In silica sol mold investment casting, the mold shell needs to be baked to increase its strength. After high-temperature preheating before pouring, the mold shell is usually removed mechanically or manually for pouring. Mechanical removal of the mold shell reduces the labor intensity of operators and minimizes heat radiation, but it requires a large space and incurs significant costs. Therefore, for small and medium-sized castings, manual mold shell forks are still commonly used for mold shell removal and pouring. Currently used mold shell forks consist of a steel pipe of suitable length with a "U" or "V" shaped fork welded to one end. During use, the fork is used to hold the mold shell pouring cup, remove the mold shell from the preheating furnace, rotate it 180°, and then insert it into the pouring cup to align with the molten steel. However, during the mold shell removal, rotation, and pouring process, problems such as mismatch between the mold shell size and the mold shell fork specifications, or the fork being unable to hold the mold shell, can cause the mold shell to detach from the opening, crack, or shatter. This reduces production efficiency, mold shell and casting yield, and increases production safety risks. Utility Model Content

[0003] The purpose of this invention is to provide a silica sol mold shell baking, casting, and insertion device, which solves the problem of mold shell falling off and breaking during the insertion process in the prior art, reduces the manufacturing and management costs of the mold shell fork, and improves production efficiency and the yield of mold shells.

[0004] The technical solution adopted in this utility model is a silica sol mold shell baking, casting, and insertion device, which includes an active slide rod. The active slide rod has a hollow cylindrical structure and a guide rod is sleeved inside. The active slide rod includes a slide rod, which has a hollow cylindrical structure and a first fixing buckle with an I-shaped cross section. The guide rod includes a round rod, one end of which is fixedly connected to a second fixing buckle with an I-shaped cross section. The round rod is sleeved inside the slide rod, and the first fixing buckle and the second fixing buckle are located at the same end.

[0005] The features of this utility model also include: The first fixing buckle has a central through hole at the center of its cross-section, which is connected to the slide rod. The first fixing buckle also has a first through hole at each end. The second fixing buckle has an I-shaped cross-section that is perpendicular to the central axis of the round rod. The second fixing buckle also has a second through hole at each end.

[0006] Several spherical notches are made on the inner wall of the slide rod; blind holes are made on the surface of the round rod, one end of the spring is fixedly connected to the bottom surface of the blind hole, and the other end of the spring is fixedly connected to one end of the spring post. The spring post is a cylinder and the other end is a spherical surface. The spring post engages with the spherical notches.

[0007] The first through hole is movably connected to one end of the drive block, and the other end of the drive block is movably connected to the clamping rod; the clamping rod is integrally formed and consists of a C-shaped plate and an oval plate; one end of the C-shaped plate of the clamping rod has a through hole that is movably connected to the drive block, and the connection between the C-shaped plate and the oval plate has a through hole that is movably connected to the second through hole.

[0008] The spherical notch is 20-50mm away from the other end face of the slide rod and is distributed along the slide rod towards the first fixed buckle.

[0009] There are 3 to 5 spherical notches, the radius of the sphere is 3 to 4 mm, and the center distance between adjacent spherical notches is 3 to 10 mm.

[0010] The outer diameter of the sliding rod is 16-24mm, the inner diameter is 14-18mm, and the length is 850-1000mm; the height of the I-shaped section of the first fixing buckle is 16-24mm, the diameter of the central through hole is 13-18mm, and the diameter of the first through hole is 7-9mm.

[0011] The blind hole has a diameter of 4-6 mm, the bottom of the blind hole is at least 3 mm away from the outer surface of the round rod, and the blind hole is located at the midpoint of the round rod; the spring has an outer diameter of 4-6 mm and a length of 4-8 mm; the spring post has a diameter of 4-6 mm, a height of 6-8 mm, and a spherical radius of 2-3 mm.

[0012] C-shaped plates have a radius of 50–70 mm, a width of not less than 6 mm, a thickness of 6–8 mm, and an opening height of 5–7 mm; oval plates have an arc diameter of 12–20 mm, a length of 40–60 mm, a thickness of 16–20 mm, and through holes at both ends with a diameter of 7–9 mm.

[0014] The beneficial effects of this utility model are: (1) This utility model can automatically lock the clamping part. By pushing the active slide bar upward, the driving block closes the clamping part. When the spring pin embedded in the guide slide bar encounters the spherical notch of the active slide bar, the clamping of the mold shell is completed under the action of the spring being squeezed and the ejection force is released. The preheated mold shell can be inserted and rotated 180° by the support lever, and the mold shell can be poured. This solves the problem of the mold shell falling off during the flipping and pouring process and causing the mold shell to break, thus improving production efficiency, mold shell and casting yield, and production safety.

[0015] (2) This utility model can flexibly adjust the opening size of the clamping part by sliding the active slide rod and the guide rod, so as to realize the insertion and pouring of the mold shell of the pouring cup with different diameters. There is no need to make insertion devices with different opening sizes, which reduces the manufacturing and management costs of the insertion device. Attached Figure Description

[0018] The following detailed description is provided in conjunction with specific implementation methods.

[0019] The silica sol mold shell baking, casting and insertion device includes an active slide rod 1, which is a hollow cylindrical structure with a guide rod 2 inside.

[0020] like Figure 1 As shown, the active slide bar 1 includes a slide bar 101, which is a hollow cylindrical structure, and the slide bar 101 is fixedly connected to the first fixing buckle 102.

[0021] like Figure 2 As shown, the cross-section of the first fixing buckle 102 is I-shaped.

[0022] like Figure 3As shown, a central through hole is formed at the center of the cross-section of the first fixing buckle 102, which communicates with the slide rod 101. That is, the I-shaped cross-section of the first fixing buckle 102 is perpendicular to the central axis of the slide rod 101. The first fixing buckle 102 has symmetrical first through holes 103 at both ends. Several spherical notches 104 are formed on the inner wall of the slide rod 101.

[0023] The slide rod 101 has an outer diameter of Φ16~24mm and an inner diameter of Φ14~18mm. It is a steel pipe with a length of 850~1000mm made of Q235~Q345 material.

[0026] The active slide bar 1 and the guide bar 2 are made of carbon structural steel (yield strength Q235~Q345).

[0027] like Figure 5 As shown, a blind hole is opened on the surface of the round rod 201. One end of the spring 3 is fixedly connected to the bottom surface of the blind hole, and the other end of the spring 3 is fixedly connected to one end of the spring post 4. The spring post 4 is a cylinder and the other end is a spherical surface.

[0028] like Figure 6 As shown, the spring post 4 embedded in the round rod 201 engages with the spherical notch 104 opened on the inner surface of the slide rod 101.

[0029] The blind hole has a diameter of Φ4~6mm, and the distance from the bottom of the blind hole to the outer surface of the round rod 201 is not less than 3mm. The blind hole is located at the midpoint of the round rod 201. The outer diameter of the spring 3 is Φ4~6mm, and the length of the spring 3 is 4~8mm. The diameter of the spring post 4 is Φ4~6mm, the height is 6~8mm, and the radius of the sphere is 2~3mm.

[0030] The fourth spring is made of 45 steel.

[0031] like Figure 7As shown, the round rod 201 is sleeved inside the slide rod 101, and the first fixing buckle 102 and the second fixing buckle 202 are located at the same end. There are two driving blocks 5 arranged symmetrically. One end of the driving block 5 is movably connected to the first through hole 103, and the other end of the driving block 5 is movably connected to the clamping rod 6. The clamping rod 6 is integrally formed and consists of a C-shaped plate and an oval plate. There are two clamping rods 6 arranged symmetrically. One end of the C-shaped plate of the clamping rod 6 has a through hole that is movably connected to the driving block 5, and the connection between the C-shaped plate and the oval plate has a through hole that is movably connected to the second through hole 203.

[0032] The C-shaped plate has a radius of 50-70mm, a width of not less than 6mm, a thickness of 6-8mm, and an opening height of 5-7mm. The oval plate has an arc diameter of Φ12-20mm, a length of 40-60mm, a thickness of 16-20mm, and through holes at both ends with a diameter of Φ7-9mm.

[0033] The drive block 5 is oval in shape, with an arc diameter of Φ12-20mm, a length of 40-60mm, and a thickness of 4-6mm. Through holes with a diameter of Φ7-9mm are opened at both ends of the drive block 5. The drive block 5 is made of 316 or 316L stainless steel.

[0034] The movable connection is a bolted connection. The bolts are M6 to M8 bolts, with a length of 20 to 30 mm and a nut height of 4 to 6 mm.

[0035] like Figure 8 As shown, clamping rod 6 clamps the mold shell pouring cup 8.

[0036] The round rod 201 is passed through the central through hole of the first fixing buckle 102 on the slide rod 101, and the round rod 201 is fitted inside the slide rod 101. Figure 9 As shown, a spring 3 and a spring post 4 are embedded in the blind hole of the round rod 201. Pulling the round rod 201 to press the spring post 4, at this time the round rod 201 and the slide rod 101 are not locked and can slide relative to each other. Two drive blocks 5 are connected to the round rod 201 with bolts 7, and two clamping rods 6 are connected to the second through hole 203 and the drive block 5 respectively with bolts 7.

[0037] When in use, pull the active slide bar 1 backward to squeeze the spring 4 and spring 3 embedded in the round rod 201 backward. The active slide bar 1 slides relative to the guide rod 2. The first fixed buckle 102 drives the drive block 5 to move backward, so that the clamping rod 6 opens and is inserted into the mold shell sprue cup 8.

[0038] like Figure 10As shown, pushing the active slide bar 1 forward causes the first fixing buckle 102 to move the drive block 5 forward, closing the opening of the clamping rod 6. When the spring pin 4 embedded in the round rod 201 encounters the spherical notch 104 on the inner surface of the slide bar 101, the compressed spring 3 releases its ejection force, automatically locking the clamping rod 6 and completing the clamping of the mold shell sprue cup 8. After inserting and rotating the preheated mold shell 180°, the mold shell can be poured, solving the problem of the mold shell breaking due to falling off during the flipping and pouring process. After pouring, the mold shell sprue cup 8 is placed on a cooling sand bed (or tooling).

[0039] Pulling the active slide bar 1 backward opens the clamping rod 6, allowing the silica sol mold shell baking and casting insertion device to be pulled out. The silica sol mold shell baking and casting insertion device can be used to insert and cast mold shells of different diameters.

[0062] A company uses silica sol investment casting, employing a three-chamber vacuum medium-frequency furnace to melt and cast high-temperature alloy shells. One mold produces one casting, with the total weight of the mold and casting after casting being 40 kg. After casting, a self-made "V"-shaped mold fork is used to insert the mold from the casting chamber. Due to the heavy weight, during the insertion process, the mold detached 5 times out of 50 insertion attempts, causing damage and bending deformation to the thin ribs at the lower part of the casting at the casting location. Subsequent welding and correction of the casting are required.

[0063] After adopting the silica sol mold shell baking, casting and insertion device of this utility model, 200 mold shells and castings were inserted and removed after casting, and no mold shells fell off. This avoided damage to the castings and deformation of the ribs, reduced the workload of subsequent fine repair and correction, improved production efficiency and reduced production costs.
