[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] In this way, when the upper mold 4 is placed on the lower mold 3, the driving structure drives the connecting block 7 to slide down along the self-locking sliding assembly until the connecting block 7 is connected to the upper mold 4, thereby connecting the entire upper mold 4 to the entire cooling liquid system to achieve heat dissipation of the upper mold 4.

[0031] The present invention provides a specific embodiment for connecting the upper mold 4 to the entire heat dissipation system: a water inlet hole 8 and a water outlet hole 9 are provided on the upper mold 4, and a filter screen 10 is provided in the water inlet hole 8 and the water outlet hole 9; at least two independent cavities 11 are provided in the connection block 7, and a nozzle 12 extending to the outside of the connection block 7 is provided on the wall of the cavity 11; one of the cavities 11 is connected to the heat dissipation channel 16 of the lower mold 3 through a hose 17, and the other cavity 11 is connected to the return pipe 6 through a hose 2 35.

[0032] The present invention provides a specific embodiment for the sliding and limiting of the connection block 7: the self-locking sliding assembly includes a mounting plate 18 fixedly arranged on the support base 1, a support slide bar 19 fixedly arranged on the mounting plate 18, a sliding bracket 20 slidably arranged on the support slide bar 19, a telescopic rod 21 fixedly connected to the bottom end of the sliding bracket 20, the connection block 7 is fixedly connected to the bottom of the telescopic rod 21, and a spring 22 is sleeved on the telescopic rod 21. A top plate 23 is fixedly installed on the top of the support slide bar 19, a one-way tooth plate 24 is fixedly connected between the top plate 23 and the mounting plate 18, a slider 25 is fixedly installed on the sliding bracket 20, and a locking tooth 26 is slidably installed on the slider 25 through a slide groove 32, a limiting rod 27 is fixedly mounted on the sliding bracket 20, and a spring 3 28 is sleeved on the limiting rod 27, a limiting slide bar 29 is also fixedly connected between the top plate 23 and the mounting plate 18, and the slider 25 is slidably sleeved on the limiting slide bar 29 through a slide hole.

[0033] In order to facilitate pouring into the pouring hole at the center of the upper mold 4 , the present invention further provides a guiding casting groove 30 on one side of the upper mold 4 .

[0034] In order to prevent the upper mold 4 from sliding after the engagement with the lower mold 3 , the present invention further provides limiting protrusions 31 at the four corners of the lower mold 3 .

[0035] The present invention also provides a specific embodiment of the driving structure:

[0036] The driving structure includes a slide groove 32 arranged on one side of the supporting base 1 , a driving bracket 33 is slidably installed in the slide groove 32 , and a driving rod 34 is installed on the driving bracket 33 .

[0037] The working principle of the present invention is:

[0038] In the first step, after the upper mold 4 and the lower mold 3 are manually closed, the limiting protrusions 31 at the four corners of the lower mold 3 can prevent the upper mold 4 from sliding horizontally.

[0039] In the second step, the driving bracket 33 is slid along the slide groove 32 manually or by a cylinder until the driving rod 34 on the driving bracket 33 is directly opposite to the top of the sliding bracket 20. The driving rod 34 is a telescopic cylinder or a linear motor. Then the driving rod 34 slides downward until it pushes the sliding bracket 20 to slide down.

[0040] In the third step, when the sliding bracket 20 drives the connection block 7 to slide down until the connection block 7 contacts the upper mold 4, the connection block 7 cannot move at this time, and the sliding bracket 20 can continue to slide down by compressing the telescopic rod 21 and the spring 22. In the process of the sliding bracket 20 sliding down, the slider 25 fixedly connected to the sliding bracket 20 follows the sliding. In the process of the slider 25 sliding down, the locking teeth 26 on the slider 25 interact with the one-way tooth plate 24 as the lower surface, and the lower surfaces of both are inclined tooth surfaces. Therefore, the extrusion of the left tooth surface of the one-way tooth plate 24 causes the locking teeth 26 to slide to the left, so that the locking teeth 26 will avoid by sliding without affecting the sliding of the slider 25.

[0041] The fourth step is that when the telescopic rod 21 and the spring 22 are compressed to the limit, the driving rod 34 stops extending and shrinks to the original state. At this time, the compressed spring 22 has a tendency to recover, and the slider 25 has a tendency to slide up. Since the locking teeth 26 on the slider 25 interact with the one-way tooth plate 24 on the upper surface, and the upper surfaces of both are flat, the locking teeth 26 cannot slide, thereby completing the self-locking of the slider 25, and then completing the locking of the sliding bracket 20, so that the compressed spring 22 transmits the restoring force to the upper mold 4 and the lower mold 3 through the connecting block 7, so that there is a certain pressure between the two;

[0042] In the fifth step, the above steps are repeated so that all the connection blocks 7 are kept in a pressurized state with the upper mold 4; since the sliding bracket 20 is limited by the supporting slide rod 19, the downward movement of the connection block 7 is limited by the telescopic rod 21, so when the connection block 7 slides down, the two nozzles 12 thereon are just embedded in the water inlet hole 8 and the water outlet hole 9 respectively, and the nozzles 12 are wrapped with rubber to achieve a sealed connection. At this time, the cooling component 2 (specifically, any device with a liquid transport function and a liquid transport function in the prior art can be used, and no specific limitation is made in the present invention) passes the cold liquid through the water outlet hole The tube 5 enters all the lower molds 3 (the number of lower molds 3 in this embodiment is 3), and the cooling liquid passes through the heat dissipation channel (not shown in the figure, which belongs to the conventional setting) in the lower mold 3 for one circle, and then enters the cavity 11 on the right side of the connection block 7 through the hose 17, and then enters the heat dissipation channel 16 in the upper mold 4 through the nozzle 12 on the right side of the connection block 7 for one circle, and then returns to the cavity 11 on the left side of the connection block 7 through the nozzle 12 on the left side, and then returns to the return pipe 6 through the hose 2 35, thereby completing the cooling connection test of the cooling component 2, and then casting can be carried out normally.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
