Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to a manifold welding device for a plastic hot runner mold. Background Art

[0002] The manifold in the plastic hot runner mold is a key component in the mold system. It is used to control the flow path of the plastic in the mold and ensure that the molten plastic flows evenly to different injection ports in the mold.

[0003] In the related art, there are various types of manifolds, which can be divided into X-type, H-type, I-type, Y-type, K-type, and others according to the flow path in the manifold. In the processing of the manifold flow path, the flow path of the manifold is difficult to process due to the presence of multiple curved paths. In the existing processing, a straight flow path is drilled and processed from the side of the manifold, and a curved path is formed at the connection point of the two straight flow paths. Then, a bolt with a circular arc surface at the end is screwed into the end channel of the straight flow path, and the circular arc surface at the end of the bolt smoothly transitions with the inner walls of the two straight flow paths.

[0004] The more flow paths a manifold has, the more holes need to be processed on the side of the manifold, the more bolts need to be set, and the processing paths must be precisely positioned during processing so that the bolts can use the arc surface to smoothly transition between two straight flow paths.

[0021] Reference Figure 2-8 The welding device includes a horizontal furnace tank 1, a tooling plate 2, a positioning plate 3, a pressing plate 4 and a hydraulic cylinder 5; one end of the furnace tank 1 is open, and a furnace door 11 is hinged on the outer side of the open end of the furnace tank 1, and the furnace door 11 is buckled on the open end of the furnace tank 1; three groups of vertical plates 12 are connected to the inner wall of the bottom of the furnace tank 1, and the top surface of each group of vertical plates 12 is connected to a support plate 13, and the support plate 13 is arranged along the axis direction of the furnace tank 1, and the three support plates 13 are evenly distributed; the tooling plate 2 is placed on the top surface of the three support plates 13, and the top surface of the tooling plate 2 is used to place the sheet diverter plate 01 ; There are multiple positioning plates 3, and the multiple positioning plates 3 are all located on the top surface of the tooling plate 2. The multiple positioning plates 3 are arranged around the sheet-like diverter plate 01. A moving mechanism 6 for driving the positioning plates 3 to move is installed on the side of the tooling plate 2, and the positioning plates 3 are close to the side of the sheet-like diverter plate 01; the clamping plate 4 is arranged in the furnace tank 1, and the hydraulic cylinder 5 is installed on the top of the outer peripheral surface of the furnace tank 1. The piston rod of the hydraulic cylinder 5 extends vertically into the furnace tank 1 and the end is connected to the top surface of the clamping plate 4; the furnace tank 1 heats the sheet-like diverter plate 01 through an electric heating wire.

[0022] First, place the sheet-shaped flow divider plate 01 on the top surface of the tooling plate 2, and stack the sheet-shaped flow divider plates 01 neatly, and drive the positioning plate 3 to move through the moving mechanism 6, so that the positioning plate 3 is close to the side surfaces of all the sheet-shaped flow divider plates 01; then, use a hand-pushed forklift to fork up the tooling plate 2, and input the tooling plate 2 into the furnace tank 1 from the opening. When the forklift transports the tooling plate 2 to between the support plate 13 and the pressing plate 4, it stops moving forward, and the forklift places the tooling plate 2 on the top surfaces of the three support plates 13, and then moves the forklift away, and closes the furnace door 11; then the furnace The tank 1 heats the manifold, and the hydraulic cylinder 5 drives the clamping plate 4 to move downward. The clamping plate 4 applies pressure to the top surface of the stacked manifolds. When the manifold reaches the welding temperature of diffusion welding, the side surfaces of adjacent sheet manifolds 01 gradually fuse under the action of pressure, so that the sheet manifolds 01 are re-bonded together to form a complete manifold. After cooling, the manifold is taken out and ground and polished without drilling holes or specially designing bolts with arc ends, thereby improving the convenience of manifold flow path processing.

[0023] There are eight positioning plates 3, two positioning plates 3 are correspondingly arranged on each side of the tooling plate 2, and there are eight moving mechanisms 6, and the eight moving mechanisms 6 correspond one to one with the eight positioning plates 3; the moving mechanism 6 includes a rotating shaft 61, a rotating plate 62, a moving frame 63 and a positioning assembly 64; two mounting openings 21 are arranged on each side of the tooling plate 2, the rotating shaft 61 is rotatably connected between the top and bottom of the mounting opening 21, one end of the rotating plate 62 is connected to the circumference of the rotating shaft 61, the moving frame 63 is installed on the end of the rotating plate 62 away from the rotating shaft 61, and the side of the positioning plate 3 is installed on the moving frame 63; the positioning assembly 64 is installed on the side of the tooling plate 2, and the positioning assembly 64 is used to limit the rotation of the rotating plate 62.

[0024] Since the shapes of the diverter plates are different, it is necessary to adjust the positioning plate 3 to press against the side of the diverter plate; when the direction of the positioning plate 3 needs to be adjusted, the restriction of the positioning assembly 64 on the rotating plate 62 is released, and the rotating plate 62 is rotated. The rotating plate 62 drives the moving frame 63 to rotate, and the moving frame 63 drives the positioning plate 3 to rotate around the axis of the rotating shaft 61, so that the positioning plate 3 is facing the side of the diverter plate.

[0025] There are two positioning assemblies 64, which are respectively located on both sides of the installation port 21; the positioning assembly 64 includes a guide plate 641, a slide plate 642, a fixed block 643, a push block 644 and a first screw 645. There are two guide plates 641, and the sides of the two guide plates 641 are connected to the sides of the tooling plate 2, and the ends of the guide plates 641 face the rotating plate 62; the sides of the two guide plates 641 close to each other are both provided with a slide groove 6411 for the slide plate 642 to slide, and the slide plate 642 faces the rotating plate 62; the fixed block 643 is connected to the side of the guide plate 641 away from the tooling plate 2, the push block 644 is connected to the side of the slide plate 642 away from the tooling plate 2, the push block 644 is located between the two guide plates 641, one end of the first screw 645 is rotatably connected to the push block 644, and the first screw 645 passes through the fixed block 643 and is threadedly transmitted with the fixed block 643.

[0026] When the rotating plate 62 is rotated and needs to be restricted, the first screw 645 is driven to rotate, and the first screw 645 drives the push block 644 to move toward the rotating plate 62, and the push block 644 drives the slide plate 642 to move toward the rotating plate 62. The two slide plates 642 are pressed against the side of the rotating plate 62, so that the rotating plate 62 is restricted and the rotating plate 62 no longer rotates, thereby improving the stability of the positioning plate 3.

[0028] As the sizes of the sheet-like diverter plates 01 are different, it is necessary to adjust the position of the positioning plate 3 on the top surface of the tooling plate 2. The second bolt is rotated, and the second bolt rotates on the top of the longitudinal support plate 631. The second bolt drives the moving block 633 to rise and fall, and the moving block 633 drives the transverse support plate 632 to rise and fall, and the transverse support plate 632 drives the positioning plate 3 to rise and fall, and the height of the positioning plate 3 is changed to make the bottom end of the positioning plate 3 fit the top surface of the tooling plate 2; when encountering a diverter plate with a larger thickness, the positioning plate 3 is raised, and the extended positioning plate 3 can be supplemented at the bottom end of the positioning plate 3; the fixing of the transverse support plate 632 by the fixing piece 635 is released, and the transverse support plate 632 is pushed and pulled, and the transverse support plate 632 drives the positioning plate 3 to move, so that the position of the positioning plate 3 on the top surface of the tooling plate 2 can be adjusted at will.

[0029] The fixing member 635 includes an extrusion block 6351, a pushing block 6352 and a third screw 6353. Two extrusion blocks 6351 are provided. The end of the moving block 633 away from the positioning plate 3 is provided with a sliding groove 6332 for the two extrusion blocks 6351 to slide. The sliding groove 6332 is connected to the two side surfaces of the moving block 633. The end surfaces of the two extrusion blocks 6351 are respectively fitted to the two side walls of the guide groove 6321; the pushing block 6352 is arranged between the two extrusion blocks 6351. The side surface of the extrusion block 6351 close to the pushing block 6352 is sloped, and the slope surface of the extrusion block 6351 is inclined upward; the two side surfaces of the pushing block 6352 are fitted with the slope surface of the extrusion block 6351; the bottom end of the third screw 6353 is rotatably connected to the top surface of the pushing block 6352, and the top end of the third screw 6353 passes through the top surface of the moving block 633, and the third screw 6353 is threadedly transmitted with the moving block 633.

[0030] When the transverse support plate 632 needs to be fixed, the third screw 6353 is rotated, and the third screw 6353 pushes the pushing block 6352 downward. The pushing block 6352 squeezes the squeezing block 6351 through the slope, and the squeezing block 6351 slides toward the sliding groove 6332. The squeezing block 6351 is pressed against the inner wall of the sliding groove 6332 of the transverse support plate 632, and the transverse support plate 632 is fixed on the moving block 633 by friction.

[0032] Since the tooling plate 2 is transported by a forklift, the sheet diverter plate 01 is easy to slide on the top surface of the tooling plate 2 when the forklift starts and stops, so the positioning plate 3 is assembled on the tooling plate 2; when the positioning plate 3 positions the sheet diverter plate 01, the height of the positioning plate 3 needs to be higher than the total height of the sheet diverter plate 01, so that all the sheet diverter plates 01 can be limited; when the clamping plate 4 is pressed down, the clamping plate 4 first contacts the auxiliary plate 322, and the retaining mechanism 7 limits the flip plate 32. The clamping plate 4 applies pressure to the auxiliary plate 322. At this time, the flip plate 32 has a tendency to rotate relative to the rotating shaft 311, and the auxiliary plate 322 drives the flip plate 32 to rotate around the rotating shaft 311, so that the flip plate 32 is bent relative to the mounting plate 31 until the clamping plate 4 is pressed against the top surface of the sheet diverter plate 01; when the clamping plate 4 is reset, the flip plate 32 is restored to a vertical state under the action of the retaining mechanism 7.
