[0002] A casting mold is a material that is made of other easily formed materials in advance in order to obtain the structural shape of a part. The mold is then placed in a sand mold, forming a cavity with the same size as the part structure. A flowing liquid is then poured into the cavity, and after the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed.

The utility model uses the arrangement mode of matching the connecting block, the pulley and the fixed block to reduce the wear of the support column and the connecting block, thereby avoiding reducing the accuracy of the connection between the upper mold and the lower mold, and improving the processing efficiency of the mold.

[0004] The applicant found that there are some shortcomings in use: after a certain period of use, the compression spring may break or lose elasticity, and when these situations occur, it needs to be replaced. In this patent, since the upper and lower ends of the compression spring are fixedly connected to the slider and the base respectively, replacement is more troublesome and takes a lot of time, affecting processing efficiency.

[0005] Therefore, the utility model designs a casting mold which is easy to process to solve the problems existing in the prior art. Utility Model Content

The downward pressure impact force of the upper mold is reduced by the restoring force of the buffer spring, so that the upper and lower molds are slowly fitted together, which has a protective effect on the upper and lower molds.

[0010] Preferably, the replacement mechanism comprises eight grooves, which are respectively provided on both sides of four chassis, and moving blocks are slidably installed in the grooves, and the grooves and the moving blocks are connected by a reset spring, a slider is installed on the side of the top of the moving block close to the reset spring, and a latch is installed on the side of the slider away from the reset spring, and limiting grooves connected with the grooves are provided on both sides of the top of the chassis, and the slider is slidably connected with the limiting grooves, and both sides of the bottom of the connecting slip ring below the buffer spring are provided with a slide groove and a socket, and the slide groove and the socket are connected, and the slide groove and the slide block are slidably connected, and the socket is slidably connected with the latch, when installing, the two moving blocks are pressed to make the moving blocks enter the grooves and squeeze the spring, and then the buffer spring and the connecting slip ring are slidably installed on the sliding column, and the slide groove is aligned with the slider, so that the chassis and the connecting slip ring below the buffer spring are fitted, and the moving block is released after fitting, and the latch is inserted into the socket through the restoring force of the reset spring, so that the chassis and the connecting slip ring below the buffer spring can be limited, and the installation of the buffer spring is completed, the operation is convenient and quick, and the processing efficiency is improved.

[0011] Preferably, a rubber layer is provided on a side of the moving block away from the return spring, and the rubber layer can improve the comfort of the staff when pressing the moving block with their fingers.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model provides a replacement mechanism, and when the buffer spring is damaged, the staff can start the cylinder and first raise the upper mold to the highest position to make the cross plate leave the sliding column, and then press the moving blocks on both sides of the chassis with two fingers respectively, the moving blocks enter the grooves and squeeze the reset springs, and the moving blocks drive the sliders to slide in the limit grooves, so that the pins leave the sockets, and the limit of the connecting slip ring below the chassis and the buffer spring can be cancelled.

[0022] See also Figure 2 In this embodiment: the buffer mechanism 7 includes four horizontal plates 701, and the four horizontal plates 701 are respectively installed at the two ends of the two limit plates 601 away from the upper mold 4. A through hole 702 is opened at one end of the horizontal plate 701 away from the limit plate 601. A chassis 703 is installed at the four corners of the top of the base 1, and a sliding column 704 is installed on the top of the chassis 703. The sliding column 704 passes through the through hole 702, and a buffer spring 705 is sleeved on the outer side of the sliding column 704. The upper and lower ends of the buffer spring 705 are installed with connecting slip rings 706 that are slidably connected to the sliding column 704. The buffer spring 705 and the two connecting slip rings 706 are an integrated structure and are replaced together. The diameter of the through hole 702 is larger than the diameter of the sliding column 704 and smaller than the diameter of the connecting slip ring 706.

[0023] See also Figure 3-4 In this embodiment: the replacement mechanism 8 includes eight grooves 801, and the eight grooves 801 are respectively opened on both sides of the four chassis 703. A moving block 802 is slidably installed in the groove 801, and the groove 801 and the moving block 802 are connected by a reset spring 803. A slider 804 is installed on the side of the top of the moving block 802 close to the reset spring 803, and a latch 805 is installed on the side of the slider 804 away from the reset spring 803.

[0025] Working principle: the cylinder 3 drives the upper mold 4 to descend, and the upper mold 4 contacts the top of the lower mold 5 for stamping. The limit plate 601 slides on the limit column 602, which can guide the upper mold 4. The limit plate 601 drives the cross plate 701 to descend at the same time. Before the upper mold 4 contacts the lower mold 5, the cross plate 701 contacts the connecting slip ring 706 above the buffer spring 705, and squeezes the buffer spring 705. Through the restoring force of the buffer spring 705, the cross plate 701 has an upward force, thereby reducing the impact force of the upper mold 4 pressing down, and protecting the upper mold 4 and the lower mold 5. When the buffer spring 705 is damaged after long-term use, the cylinder 3 drives the upper mold 4 to rise to the highest point, so that the cross plate 701 leaves the slide column 704, and then presses the moving blocks 802 on both sides of the chassis 703 with two fingers, so that the moving blocks 802 enter the groove 801 and squeeze The reset spring 803 and the moving block 802 drive the slider 804 to move, so that the pin 805 leaves the socket 808, and the limit of the connecting slip ring 706 below the buffer spring 705 can be cancelled. The staff will take the connecting slip ring 706 and the buffer spring 705 upward from the sliding column 704 for replacement. During installation, the moving block 802 is also pressed, and then the connecting slip ring 706 is slid and installed on the slider 804, and the slide groove 807 is aligned with the slider 804, so that the limiting groove 806 below the pin 805 is in contact with the chassis 703, and then the moving block 802 is released. The restoring force of the reset spring 803 makes the moving block 802 automatically pop up, thereby driving the slider 804 and the pin 805 to move, and the pin 805 enters the socket 808, which can limit the pin 805.
