Technical Field

[0001] The utility model relates to the technical field of processing equipment for mold making, in particular to a drilling equipment for mold making. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry". In the process of mold making, its surface needs to be worked, so a drilling machine is needed for drilling. Drilling machine refers to a general term for machinery and equipment that uses a harder and sharper tool than the target object to leave a cylindrical hole or hole on the target object by rotary cutting or rotary extrusion. It is also called a drilling machine, a punching machine, a drilling machine, a through-hole machine, etc.

[0003] At present, when the current drilling equipment for mold making is drilling, the workbench cannot rotate. Therefore, when processing annular through holes, it is very inconvenient to move the mold with one hand and operate the equipment with the other hand. At the same time, the mold is heavy and moves with hard friction against the workbench, which makes it difficult to move and also causes damage to the mold surface, thereby reducing the service life of the mold and causing premature wear, which greatly reduces the convenience of use of the drilling equipment for mold making and the service life of the mold. Summary of the invention

[0004] The main purpose of the utility model is to solve the problem that the above-mentioned existing drilling equipment for mold making does not have a rotatable movable table, so it is not convenient to adjust the angle of the mold during use, and the operator needs to adjust the angle by lifting or hard rubbing the mold, which reduces the convenience of use and also reduces the service life of the mold. A drilling equipment for mold making is provided.

[0005] The specific scheme of the utility model is: a drilling device for mold making, comprising a drilling mechanism and a workbench, the interior of the workbench is hollow and the top is provided with a slot, a movable table is rotatably installed in the slot, the movable table matches the slot, a rotating mechanism is provided at the bottom of the movable table, the rotating mechanism comprises a connecting rod, the connecting rod is fixedly connected to the bottom of the movable table, a threaded block is provided at the bottom end of the connecting rod, a rotating cylinder is provided below the threaded block, an opening is provided at the top of the rotating cylinder and a threaded groove is provided inside, the threaded block is threadedly matched with the threaded groove, so that the connecting rod and the rotating cylinder are threadedly connected, the diameter of the threaded block is larger than the diameter of the opening, a bearing a is rotatably connected to the bottom of the rotating cylinder, the bearing a is provided at the bottom end of the workbench and below the rotating cylinder, a gear a is provided on the surface of the rotating cylinder, one end of the gear a is meshedly connected with a gear b, and the gear b is connected to a driving mechanism.

[0006] According to the above technical solution, the driving mechanism drives gear b to rotate, and gear b drives gear a to rotate, thereby achieving the effect of driving the rotating drum to rotate and realizing the rotation of the movable table, which is convenient for rotating the mold at a uniform speed when processing the circular hole, or rotating the mold when adjusting the angle, avoiding the need to move the mold with both hands or rubbing the mold on the workbench, which is very inconvenient and will also cause wear on the mold surface.

[0007] Furthermore, the driving mechanism includes a rocker, which is fixedly connected to gear b. A bearing b is provided inside the workbench. One end of the rocker away from gear b passes through the bearing b and is rotatably connected. One end of the rocker away from the bearing b extends to the outside of the workbench and is rotatably connected. The gear a is a flat gear, and the gear b is a bevel gear.

[0008] According to the above technical solution, the rocker drives the gear b to rotate to achieve the driving effect, which is more convenient to use and easy for the operator to control.

[0009] Furthermore, a fixing mechanism is provided on one side of the gear a, and the fixing mechanism includes a threaded seat, and the threaded seat is arranged at the bottom end inside the workbench.

[0010] According to the above technical solution, the card is driven to move toward the side of gear a by rotating the threaded rod, so that the card contacts gear a to increase friction and form a limiting effect to prevent gear a from rotating, thereby achieving the effect of fixing the movable platform.

[0011] Furthermore, the card is in the shape of a plate, a counterweight is provided at the bottom of the card, the card and the bottom of the workbench are perpendicular to each other, and the width of the card is adapted to the tooth gap of gear a.

[0012] According to the above technical solution, the plate shape can facilitate the card to be inserted into the gap between the teeth of gear a, and the counterweight block can effectively ensure that the card is vertically perpendicular to the bottom of the workbench, which is convenient for limiting the gear a.

[0013] Furthermore, a sealing ring is provided at the top of the slot, and the sealing ring is tightly attached to the movable platform.

[0014] According to the above technical solution, the gap of the slot can be effectively reduced by the sealing ring, so as to prevent the movable platform from bringing its impurities into the slot when it is raised or lowered.

[0015] Furthermore, the movable height of the thread block in the thread groove is 1 mm to 5 mm.

[0016] According to the above technical solution, by limiting the movable height of the movable table, it is convenient to raise the movable table so that a certain gap is provided between the movable table and the surface of the workbench, so that the movable table can be easily rotated.

DETAILED DESCRIPTION

[0027] Embodiment 1

[0028] See also Figure 1-8 The present embodiment is a drilling device for mold making, which is composed of a drilling mechanism 1 and a workbench 2. The drilling mechanism 1 is used to drill holes on the mold surface. The workbench 2 is a working platform for placing the mold during drilling. The workbench 2 is hollow inside and has a circular slot 3 on the top. A circular movable table 4 matching the slot 3 is rotatably installed in the slot 3. The movable table 4 is used to assist the top mold to rotate and adjust. A rotating mechanism is connected to the bottom of the movable table 4. The rotating mechanism is used to assist the movable table 4 to rotate. The rotating mechanism includes a connecting rod 5, which is vertically fixed to the bottom of the movable table 4. A threaded block 6 is fixed to the bottom of the connecting rod 5. A rotating drum 7 is provided below the threaded block 6. The top of the rotating drum 7 is open and A thread groove 8 is provided inside, and the opening is connected to the thread groove 8 and the diameter of the opening is smaller than the diameter of the thread groove 8. The thread block 6 is threadedly matched with the thread groove 8, so that the connecting rod 5 is threadedly connected to the rotating drum 7. The diameter of the thread block 6 is larger than the diameter of the opening to prevent the thread block 6 from falling off the thread groove 8. The bottom of the rotating drum 7 is passed through the bearing a9 for rotation. The bottom of the bearing a9 is welded to the bottom end of the inside of the workbench 2 and is located directly below the rotating drum 7. A gear a10 is welded on the surface of the rotating drum 7. The gear a10 is located above the bearing a9. One end of the gear a10 is meshedly connected with the gear b11. The gear b11 is connected to a driving mechanism, such as a motor or other driving structure to drive it, thereby achieving the effect of driving the gear b11 to rotate.

[0029] Furthermore, a rubber sealing ring 12 is fixed at the top of the inner side of the slot 3 , and the sealing ring 12 is wrapped tightly against the surface of the movable table 4 , which can maximize the gap between the slot 3 and the movable table 4 to prevent dust and iron filings from entering the interior of the workbench 2 .

[0030] Furthermore, the movable height of the thread block 6 in the thread groove 8 is only 1mm~5mm, which can effectively ensure the gap between the movable table 4 and the workbench 2 when the movable table 4 is raised, facilitate flexibility when rotating the movable table 4, and also avoid the situation where the mold is unstable due to excessive raising.

[0031] The working principle of this embodiment is as follows: when the motor or other driving mechanism controls the gear b11 to rotate forward, the gear b11 drives the gear a10 to rotate, so that the gear a10 drives the rotating drum 7 to rotate on the bearing a9. When the rotating drum 7 rotates forward, the thread block 6 makes a rotational motion in the thread groove 8. When the thread block 6 makes a rotational motion, it drives the connecting rod 5 to make a linear upward motion inside it, thereby achieving the effect of raising the movable platform 4. When the thread block 6 moves to the top of the thread groove 8, it is limited by the diameter of the top opening of the rotating drum 7, which prevents the thread block 6 from falling off the thread groove 8. At this time, the movable platform 4 drives the top mold to rise by 5mm, avoiding the situation where the mold itself contacts the surface of the workbench 2 and is affected by friction, resulting in the movable platform 4 being unable to rotate. When the thread block 6 cannot When rising, the thread block 6 drives the movable table 4 to rotate forward, thereby achieving the effect of adjusting the mold angle. At the same time, it is also convenient for processing annular holes. There is no need for the operator to lift the mold with both hands or rub it on the workbench 2, which greatly improves the convenience of moving the mold angle and reduces the wear of the mold when it rotates. After use, the motor or other driving mechanism is controlled to reverse. At this time, the thread block 6 rotates in the opposite direction in the thread groove 8, thereby achieving the effect of descending. When the thread block 6 reaches the bottom of the thread groove 8, the movable table 4 and the workbench 2 become in a horizontal line, completing the storage of the movable table 4, and in the process of lifting the movable table 4, the surface of the movable table 4 is in close contact with the sealing ring 12, which prevents dust or iron filings from being brought into the workbench 2, further improving the practicality.

[0032] Embodiment 2

[0033] The structure of this embodiment is basically the same as that of the first embodiment, and the following features are added on the basis of the first embodiment: the driving mechanism includes a rocker 13, the rocker 13 is used to control the rotation of the gear b11, the rocker 13 is welded and fixed to the right end of the gear b11, a bearing b14 is fixed inside the workbench 2, the end of the rocker 13 away from the gear b11 passes through the bearing b14 and can rotate on the bearing b14, the end of the rocker 13 away from the bearing b14 continues to extend to the right side and passes through the side wall of the workbench 2 and can rotate in the rotating hole 15, the gear a10 is a flat gear, and the gear b11 is a bevel gear to facilitate the transmission effect.

[0034] The working principle of this embodiment is as follows: when the movable platform 4 needs to be controlled to rotate, the rocker 13 on the side wall of the workbench 2 is shaken manually, and the rocker 13 rotates in the bearing b14 and the rotating hole 15, thereby achieving the effect of driving the gear b11 to rotate. When the gear b11 rotates, it can drive the gear a10 to rotate, thereby achieving a lifting effect.

[0035] Embodiment 3

[0036] The present embodiment is basically the same in structure as the first and second embodiments, and the following features are added on the basis of the first and second embodiments: a fixing mechanism is provided on one side of the gear a10, and the fixing mechanism includes a threaded seat 16, the threaded seat 16 is fixed to the bottom end of the inside of the workbench 2 and is hollowed out in the middle and provided with threads, a transversely arranged threaded rod 17 is threadedly connected to the inside of the threaded seat 16, a bearing c18 is embedded in the left end of the threaded rod 17, a rotating shaft 19 is rotatably connected in the bearing c18, a card 20 is welded to one end of the rotating shaft 19, and the card 20 is parallel to one side of the gear a10, a screw hole 21 is provided on the side wall of the surface of the workbench 2, the screw hole 21 is coaxial with the hole with threads hollowed out in the middle of the threaded seat 16, the right end of the threaded rod 17 away from the threaded seat 16 passes through the screw hole 21 and is threadedly connected thereto, and the fixing mechanism is used to limit the gear a10 to prevent the movable table 4 from rotating by itself.

[0037] Furthermore, the card 20 is in the shape of a plate, and a counterweight block 22 is provided at the bottom of the card 20, so that the card 20 can continue to maintain the effect of vertically perpendicular to the workbench 2, so that the card 20 can be easily inserted into the teeth of the gear a10 for limiting when fixed, and at the same time, the width of the card 20 is adapted to the gap width between the teeth of the gear a10.

[0038] The working principle of this embodiment is as follows: when it is necessary to fix the movable table 4, the threaded rod 17 outside the workbench 2 is rotated by manpower, and the threaded rod 17 rotates in the screw hole 21 and the threaded seat 16, so that the threaded rod 17 moves to one side, thereby driving the card 20 to approach the gear a10. Since a counterweight block 22 is provided at the bottom of the card 20 and a bearing c18 is provided at one end, when the threaded rod 17 rotates and moves, the card 20 is made to continue to be downward and perpendicular to the bottom of the workbench 2 through the counterweight block 22, and can rotate in the bearing c18 at the same time, so it will not affect the vertical downward shape of the card 20. When the card 20 contacts the gear a10, the card 20 enters the gear a10 tooth gap for clamping and limiting, thereby fixing the gear a10 to prevent it from rotating, thereby achieving the effect of fixing the movable table 4, further improving the practicality of the drilling equipment for mold making.
