Description

Technical Field

[0001] This utility model relates to the field of transfer device technology, and in particular to a transfer device for precision mold manufacturing. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of objects by changing the physical state of the material being molded. It is often referred to as the "mother of industry."

[0003] In Chinese utility model patents, such as CN221757595U, a transfer device for precision mold manufacturing is disclosed. The circular limiting plate can be driven to move downward by the lead screw. As the sliding sleeve moves downward, the tilt angle of the four inclined rods can be changed accordingly. This allows the four limiting baffles to effectively limit the outside of the mold at the same time, which is convenient for quickly and effectively limiting irregular molds and improving the protection of the mold during transfer.

[0004] The above-mentioned technology improves the protection of the mold during transfer by simultaneously limiting the outside of the mold with four limiting baffles. However, for multi-faceted and irregular molds, the simultaneous movement of multiple limiting baffles cannot guarantee that each limiting baffle fits the outer contour of the mold, and cannot achieve comprehensive and tight limiting. As a result, there is still a risk of shaking or displacement of the mold during transfer. In view of this, this application proposes a transfer device for precision mold manufacturing. Utility Model Content

A second sealing piston is fixedly installed on the outer side of the screw sleeve through multiple connecting rods, and the second sealing piston is slidably connected inside the gas injection box. An air extraction pipe is fixedly connected to the outer side of the gas injection box. The gas injection box is connected to an annular seat through a connecting pipe. A one-way valve is installed in both the connecting pipe and the air extraction pipe. A driving mechanism is provided on the outer side of the top plate, and the driving mechanism drives the reciprocating screw to rotate.

[0009] Preferably, the drive mechanism includes a rocker arm, which is rotatably connected to the outside of the top plate. A drive gear is mounted on the rocker arm. One end of the reciprocating screw passes through the air injection box and is equipped with a driven gear, which meshes with the drive gear.

[0012] Preferably, a placement box is fixedly installed on the top surface of the push frame, and a rubber pad is fixedly installed on the end of each clamping rod away from the first sealing piston.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, by setting up a gas injection mechanism, a first sealing piston, a clamping rod, a return spring, an annular seat, etc., realizes that starting the gas injection mechanism drives the gas to be delivered to the annular seat, and pushes the first sealing piston to slide outward, thereby mobilizing the clamping rod to clamp the mold.

Furthermore, the return spring facilitates the reset of the first sealing piston.

[0015] 2.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] This utility model provides a technical solution: such as Figure 1-3As shown, a transfer device for precision mold manufacturing includes a pusher frame 1, a top plate 2 fixedly mounted on the top surface of the pusher frame 1, an annular seat 3 fixedly mounted on the top surface of the top plate 2, a plurality of telescopic sleeves 8 fixedly and connected to the inner side of the annular seat 3, and the plurality of telescopic sleeves 8 are symmetrically distributed around the center of the annular seat 3. A first sealing piston 12 is slidably connected inside each telescopic sleeve 8, a clamping rod 9 is fixedly mounted on the outer side of each first sealing piston 12, and a return spring 11 is installed on the outer side of each first sealing piston 12 and the bottom wall of the corresponding telescopic sleeve 8. An air injection box 5 is fixedly mounted on the bottom surface of the top plate 2, an air injection mechanism is provided inside the air injection box 5, and the air injection mechanism is connected to the annular seat 3. An exhaust pipe 6 is fixedly and connected to the outer side of the annular seat 3, and a valve 7 is installed on the exhaust pipe 6.

[0022] Air is injected into the annular seat 3 through the air injection mechanism, thereby pushing each first sealing piston 12 to slide outward until the clamping rod 9 abuts against the outer side of the mold. Then the airflow is redistributed until each clamping rod 9 abuts against the outer side of the mold, thus completing the clamping and limiting of the mold. It can adapt to multi-faceted and irregular molds, thereby reducing the risk of mold transfer. At the same time, multiple return springs 11 facilitate the reset of each first sealing piston 12 after the valve 7 is opened.

[0023] Furthermore, the gas injection mechanism includes a reciprocating screw 15, which is rotatably connected to the side wall of the gas injection box 5. A screw sleeve 16 is threaded onto the reciprocating screw 15 and is slidably connected inside the gas injection box 5. A second sealing piston 18 is fixedly installed on the outside of the screw sleeve 16 through multiple connecting rods 17 and is slidably connected inside the gas injection box 5. An exhaust pipe 14 is fixedly connected to the outside of the gas injection box 5. The gas injection box 5 is connected to the annular seat 3 through a connecting pipe 13. A one-way valve is installed in both the connecting pipe 13 and the exhaust pipe 14. A drive mechanism is provided on the outside of the top plate 2, and the drive mechanism drives the reciprocating screw 15 to rotate. It should be noted that the one-way valve can fix the gas flow direction. Through the reciprocating sliding of the second sealing piston 18, gas from the outside can be drawn through the exhaust pipe 14 and enter the gas injection box 5, and then pushed into the annular seat 3 through the connecting pipe 13.

[0024] Furthermore, the drive mechanism includes a rocker arm 21, which is rotatably connected to the outside of the top plate 2. A drive gear 22 is mounted on the rocker arm 21. One end of the reciprocating screw 15 passes through the air injection box 5 and is equipped with a driven gear 20. The driven gear 20 meshes with the drive gear 22. By rotating the hand rocker arm 21, the reciprocating screw 15 can be driven to rotate. Since the reciprocating screw 15 and the screw sleeve 16 have self-locking properties, the second sealing piston 18 will not slide without cause.

[0025] Furthermore, a baffle 19 is fixedly installed at the end of the reciprocating screw 15 away from the driven gear 20, and the diameter of the baffle 19 is greater than the diameter of the reciprocating screw 15 to prevent the screw sleeve 16 from disengaging from the reciprocating screw 15.

[0026] Furthermore, the pitch circle diameter of the driven gear 20 is smaller than that of the driving gear 22, which can increase the rotational speed of the driven gear 20.

[0027] Furthermore, a placement box 4 is fixedly installed on the top surface of the pusher 1 to facilitate the placement of other parts. A rubber pad 10 is fixedly installed on the end of each clamping rod 9 away from the first sealing piston 12 to avoid clamping damage to the mold.

[0028] This utility model provides a transfer device for precision mold manufacturing. The specific working principle is as follows: When using it, the operator first places the mold in the annular seat 3, then holds the rocker arm 21 to drive the drive gear 22 to rotate, thereby driving the driven gear 20 to rotate rapidly, which in turn causes the reciprocating screw 15 to rotate. Through the cooperation of the screw sleeve 16 and the connecting rod 17, the second sealing piston 18 is driven to slide back and forth, thereby drawing external gas through the air extraction pipe 14 into the air injection box 5, and then transporting the gas into the annular seat 3 through the connecting pipe 13. Since each telescopic sleeve 8 is connected to the annular seat 3, the gas pushes the first sealing piston 12 in each telescopic sleeve 8 to slide outward, thereby causing each clamping rod 9 to slide outward and abut against the outside of the mold. When all the clamping rods 9 abut against the outside of the mold, the rocker arm 21 can be stopped. At this time, due to the self-locking property of the thread, the position of the second sealing piston 18 is fixed, and the position of each clamping rod 9 is also fixed, thereby providing stable clamping of the mold from multiple sides.

[0029] Next, the staff can push the pusher frame 1 to move the mold. When it is transported to the designated place, the valve 7 can be manually adjusted to open the exhaust pipe 6. Each first sealing piston 12 is reset under the action of the return spring 11, so that the gas in the annular seat 3 is discharged through the exhaust pipe 6 for the next use.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
