Description

Technical Field

[0001] The utility model relates to the technical field of casting moulds, in particular to a mould for processing automobile castings. Background Art

[0002] Casting is a method of pouring liquid metal into a casting cavity that matches the shape of the part, and then waiting for it to cool and solidify to obtain a part or blank. Many large parts in automobiles are cast through casting molds during the manufacturing process. However, after the products in the existing casting molds are cooled and formed, they are easily stuck between the molds and are not easy to demold. Moreover, after the upper and lower molds are closed, the molten material will lift the mold, so that the mold is not closed, resulting in product scrapping. In order to solve the above problems, a technical solution is disclosed in patent number: CN202320878758.X for solving the above problems. Although the patent can solve the above problems, the technical solution still has some problems when working. When the two molds are engaged, the locking mechanism on the side can be used for engagement. However, the mechanism needs to be manually opened during the engagement process. At the same time, manual operation is also required when taking the material to push the material out of the mold. This operation causes more manual operation steps when the equipment is working, thereby reducing the production efficiency of the equipment, and at the same time reducing the practicality and convenience of use of the equipment.

[0003] Based on this, the utility model designs a processing die for automobile castings to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a mold for processing automobile castings, so as to solve the problem that the equipment proposed in the above background technology is not convenient enough to use, resulting in low efficiency of the equipment.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A mold for processing automobile castings, comprising a lower mold and an upper mold, the lower mold is movably connected to the upper mold, plug-in grooves are provided on the left and right sides of the lower mold, and locking mechanisms are provided on the left and right sides of the lower mold, the locking mechanism is located on one side of the plug-in groove, a pushing mechanism is provided on the lower side of the lower mold, a rotating rod is rotatably connected to the lower side of the lower mold, the rotating rod and two locking mechanisms are transmission connected, a torsion spring is sleeved on the rotating rod, two cams are installed on the rotating rod, the cam and the pushing mechanism are movably connected, a full gear is installed on the rotating rod, a driving mechanism is installed on the lower mold, the driving mechanism and the full gear are meshed and connected, two plug-in plates are fixedly connected to the lower side of the upper mold, a locking groove is provided on the plug-in plate, the plug-in plate is movably connected in the plug-in groove, and the locking groove and the locking mechanism are movably connected.

[0007] Preferably, the locking mechanism includes a rotating sleeve, a threaded rod, a first spring, a locking rod and a limiting rod. One side of the lower die is rotatably connected to the rotating sleeve, the rotating sleeve is internally threaded with the threaded rod, one end of the threaded rod is fixedly connected to the first spring, one end of the first spring is fixedly connected to the locking rod, and a limiting rod is arranged between the threaded rod and the lower die.

[0008] Preferably, the locking rod is slidably connected in the insertion slot, one end of the locking rod is arc-shaped, and the locking rod is movably inserted in the locking slot.

[0009] Preferably, the material pushing mechanism includes a sliding rod, a second spring, a pushing plate and a connecting plate. Two sliding rods are slidably connected to the lower die, the second spring is sleeved on the sliding rod, one end of the second spring is provided with the pushing plate, and a connecting plate is fixedly connected between the two sliding rods.

[0010] Preferably, the driving mechanism includes a driving motor and a semi-gear. The driving motor is installed on the lower die, the output end of the driving motor is fixedly connected to the semi-gear, and the semi-gear is meshed with the full gear.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model controls the upper die and the lower die to engage. During the engagement process of the upper die and the lower die, the insertion plate is inserted into the insertion groove, so that the upper die and the lower die are more accurate when being clamped. As the upper die descends, the insertion plate presses the locking rod, causing the locking rod to press the first spring. When the insertion plate moves to a suitable position, the locking rod is inserted into the locking groove. At this time, the first spring resets, and a clamping is formed between the upper die and the lower die. At this time, the material can be poured, and the locking mechanism can effectively ensure the fixation between the upper die and the lower die, avoiding the formation of a gap between the upper die and the lower die during the pouring process, thereby affecting the product quality. When the product is formed, the driving motor is controlled to drive the semi-gear to rotate. At this time, the semi-gear drives the full-gear to work. When the rotating rod rotates, the cam starts to rotate. At the same time, the rotating rod drives the rotating sleeve to rotate. When the rotating sleeve rotates, the threaded rod moves outward from the rotating sleeve under the control of the limiting rod. During the movement of the threaded rod, the threaded rod pulls the first spring and the locking rod to move. When the threaded rod moves to a suitable position, the locking rod and the locking groove are disengaged. At the same time, the cam starts to press the connecting plate, and then the upper die is lifted. The cam continuously presses the connecting plate, causing the sliding rod to move upward, and at the same time, the second spring is compressed. When the material in the lower die is lifted, people can take out the material. At the same time, the semi-gear and the full-gear are disengaged, and the torsion spring controls the rotating rod to reverse, thereby causing the sliding rod and the locking rod to reset simultaneously. In this way, the next material pouring can be carried out. The various parts in the equipment cooperate, making the equipment more convenient for locking and material taking, reducing the steps of manually opening and taking materials when the equipment locks, opens, and takes materials each time, and further improving the working efficiency of the equipment, making the equipment more integrated and more efficient and faster during operation.

A full gear 18 is installed on the rotating rod 15. A driving mechanism 19 is installed on the lower die 1. The driving mechanism 19 is meshed with the full gear 18. Two insertion plates 22 are fixedly connected to the lower side of the upper die 2. Locking grooves 23 are opened on the insertion plates 22. The insertion plates 22 are movably connected in the insertion slots 3, and the locking grooves 23 are movably connected to the locking mechanisms 4.

[0022] Among them, the locking mechanism 4 includes a rotating sleeve 5, a threaded rod 6, a first spring 7, a locking rod 8 and a limiting rod 9. A rotating sleeve 5 is rotatably connected to one side of the lower die 1. The threaded rod 6 is threadedly connected in the rotating sleeve 5. One end of the threaded rod 6 is fixedly connected to a first spring 7. One end of the first spring 7 is fixedly connected to a locking rod 8. A limiting rod 9 is provided between the threaded rod 6 and the lower die 1; it is convenient for the fixation between the upper die 2 and the lower die 1, making it more stable during pouring.

[0023] Among them, the locking rod 8 is slidably connected in the insertion slot 3. One end of the locking rod 8 is arc-shaped. The locking rod 8 is movably inserted into the locking groove 23; it is convenient for the locking between the insertion plate 22 and the locking rod 8, making it more stable and convenient to use.

[0024] Among them, the pushing mechanism 10 includes a slide bar 11, a second spring 12, a push plate 13 and a connecting plate 14. Two slide bars 11 are slidably connected to the lower mold 1.

[0026] Working principle:

[0027] When working, the upper mold 2 and the lower mold 1 are controlled to engage. During the engagement of the upper mold 2 and the lower mold 1, the plug-in plate 22 is plugged into the plug-in slot 3, so that the upper mold 2 and the lower mold 1 are more accurately engaged. As the upper mold 2 descends, the plug-in plate 22 squeezes the locking rod 8, so that the locking rod 8 squeezes the first spring 7. When the plug-in plate 22 moves to a suitable position, the locking rod 8 is plugged into the locking slot 23. At this time, the first spring 7 is reset, and the upper mold 2 and the lower mold 1 are engaged. At this time, the material can be poured, and the locking mechanism 4 can effectively ensure the fixation between the upper mold 2 and the lower mold 1, avoiding the formation of a gap between the upper mold 2 and the lower mold 1 during the pouring process, thereby affecting the quality of the product. After the product is formed, the driving motor 20 is controlled to drive the half gear 21 to rotate. At this time, the half gear 21 drives the full gear 18 to work. When the rotating rod 15 rotates, the cam 17 starts to rotate, and at the same time, the rotating rod 15 drives the rotating sleeve 5 to rotate. When the rotating sleeve 5 rotates, the screw The threaded rod 6 moves toward the outside of the rotating sleeve 5 under the control of the limit rod 9. During the movement of the threaded rod 6, the threaded rod 6 pulls the first spring 7 and the locking rod 8 to move. When the threaded rod 6 moves to a suitable position, the locking rod 8 and the locking groove 23 are disengaged, and the cam 17 starts to squeeze the connecting plate 14, and then moves the upper mold 2 upward, and the cam 17 continues to squeeze the connecting plate 14, so that the slide bar 11 moves upward, and the second spring 12 is compressed. When the material in the lower mold 1 is lifted up, people can take out the material, and at the same time the half gear 21 and the full gear 18 are disengaged, and the torsion spring 16 controls the rotating rod 15 to reverse, and then the slide bar 11 and the locking rod 8 are reset at the same time, so that the next material can be poured, and the various parts in the equipment cooperate to make the equipment more convenient in locking and taking materials, and reduce the steps of manual opening and taking materials each time the equipment is locked, opened and taken, thereby further improving the working efficiency of the equipment, making the equipment more integrated, more efficient and faster at work.
