Description

Technical Field

[0001] This utility model relates to a tee production mold, and more particularly to a sequential core-pulling mold. Background Technology

[0002] Existing downstream tees are generally Y-shaped, so their molds only require linear movement during core pulling. However, there is another type of downstream tee with an eccentric connection (…). Figure 4 This means that the connection between the branch pipe and the main pipe is not perpendicular, but rather connected by a short arc in the direction of water flow. Due to the arc design at the connection, the original straight-line core-pulling method of the mold is no longer applicable. The current production method involves manual core pulling by workers after mold opening, which is not conducive to improving production efficiency. Therefore, it is necessary to design a mold that allows for sequential core pulling. Summary of the Invention

[0003] This invention provides a sequential core-pulling mold to solve the above-mentioned problems.

[0004] To solve the above problems, the technical solution of this utility model is: a sequential core-pulling mold, which includes an upper mold and a lower mold. A lower concave mold is fixedly installed on the lower mold. Both ends of the lower concave mold are provided with a demolding mechanism I with the same structure. A demolding mechanism II is also installed on the lower mold.

[0005] The demolding mechanism includes a slide groove, in which a slider is provided that can slide horizontally. The slider has an oblique hole, the bottom of which is away from the lower die. A core puller is fixedly installed on one of the two adjacent sliders.

[0006] The demolding mechanism 2 includes a slider seat, on which a groove 2 is provided, and a slider 2 that can slide horizontally within the groove 2 is provided. The slider 2 has an oblique hole 2, the bottom of which is away from the lower die. A core puller 2 is fixedly installed on the side of the slider 2 adjacent to the lower die. A core puller 3 is fixedly installed on the slider seat, the core puller 3 penetrates the slider 2 and is located inside the core puller 2, and the end of the core puller 3 near the lower die is arc-shaped.

[0007] A rotating shaft is fixedly installed at one end of the slider seat near the lower die. A driving mechanism is also installed on the lower die, which can drive the slider seat to move around the rotating shaft.

[0008] The bottom of the upper mold is fixedly installed with an upper concave mold that mates with the lower concave mold, and an inclined column that mates with inclined hole one and inclined hole two is also fixedly installed.

[0009] As a further improvement of this utility model, the driving mechanism includes an oil cylinder fixedly installed on the lower mold, the rotating shaft is fixedly connected to a gear, the gear is rotatably installed on the lower mold, the gear meshes with a rack, and the movable end of the oil cylinder is fixedly connected to the rack.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] exist Figures 1 to 4 Among them, a sequential core-pulling mold is composed of an upper mold 1 and a lower mold 3, characterized in that: a lower concave mold 14 is fixedly installed on the lower mold 3, and both ends of the lower concave mold 14 are provided with a demolding mechanism 1 with the same structure, and a demolding mechanism 2 is also installed on the lower mold 3;

[0021] The demolding mechanism includes a slide groove 41, in which a slider 4 is provided that can slide horizontally. The slider 4 is provided with an oblique hole 42. The bottom of the oblique hole 42 is away from the lower die 14. A core puller 43 is fixedly installed on one side of the two adjacent sliders 4.

[0022] The second demolding mechanism includes a slider seat 72, on which a second groove is provided. A second slider 7, which can slide horizontally within the second groove, is provided on the second slider 7. A second inclined hole 73 is provided on the second slider 7. The bottom of the second inclined hole 73 is away from the lower die 14. A second core puller 74 is fixedly installed on the side of the second slider 7 adjacent to the lower die 14. A third core puller 71 is fixedly installed on the slider seat 72. The third core puller 71 passes through the second slider 7 and is located within the second core puller 74. The end of the third core puller 71 near the lower die 14 is arc-shaped.

[0023] A rotating shaft 13 is fixedly installed on one end of the slider seat 72 near the lower die 14. A driving mechanism is also installed on the lower die 3. The driving mechanism can drive the slider seat 72 to move around the rotating shaft 13.

[0024] The bottom of the upper mold 1 is fixedly installed with an upper concave mold that cooperates with the lower concave mold 14, and an inclined column 2 that cooperates with inclined hole 42 and inclined hole 73 is also fixedly installed.

[0025] Furthermore, the driving mechanism includes a hydraulic cylinder 8 fixedly mounted on the lower mold 3, a rotating shaft 13 fixedly connected to a gear 12, the gear 12 rotatably mounted on the lower mold 3, the gear 12 meshing with a rack 11, and the movable end of the hydraulic cylinder 8 fixedly connected to the rack 11.

[0026] Furthermore, a limiting plate 9 is provided at the bottom of the slider seat 72. The limiting plate 9 is fixedly installed on the lower mold 3. An arc groove 10 is provided on the limiting plate 9. A limiting post that can move within the arc groove 10 is fixedly installed at the bottom of the slider seat 72.

[0027] Furthermore, a limit baffle is fixedly installed at the end of the slide groove 41 away from the lower die 14.

[0028] Furthermore, a guide block 15 is provided on the rack 11, and the rack 11 can move linearly on the guide block 15.

[0029] When the mold opens, the upper mold 1 moves upward. Since the upper mold is fixedly installed with inclined pillars 2 that mate with inclined holes 42 and 73, and the bottoms of inclined holes 42 and 73 are far away from the lower die 14, when the upper mold 1 moves upward, the inclined pillars 2 will drive sliders 4 and 7 to move away from the lower die 14, causing core pullers 43 and 74 to separate from the workpiece 6 first. At this time, since core puller 71 is fixedly installed on slider seat 72, and slider 7 has a circular hole for core puller 71 to pass through, core puller 71 remains stationary, and slider 7 can move linearly along core puller 7. After the upper mold 1 completes its upward movement, the hydraulic cylinder 8 is activated. The hydraulic cylinder 8 pushes the rack 11, causing it to move on the guide block 15. The rack 11 drives the gear 12 to rotate around the rotating shaft 13. Since the rotating shaft 13 is fixedly connected to the slider seat 72, the rotation of the gear 12 causes the second core puller 74 and the third core puller 71 on the slider seat 72 to rotate together, so that the arc-shaped end of the third core puller 71 is completely dislodged from the workpiece 6. At this time, the workpiece 6 can be removed. The hydraulic cylinder 8 resets and pulls the rack 11. The rack 11 drives the gear 12 to rotate around the rotating shaft 13, so that the second slide 7 is reset. The upper mold 1 moves downward, and the inclined column 2 drives the first slide 4 and the second slide 7 to move to the lower die 14 through the inclined hole 42 and the inclined hole 73. At this time, the mold closes and production continues.
