[0006] By adopting the above technical solutions, after the product is formed, the driving part two drives the core-pulling block two to slide so that the core-pulling block two slides into the core-pulling block one, and the reverse locking structure of the core-pulling block two and the support body is released. Then the driving part one drives the core-pulling block one to move to release the reverse locking structure of the driving part one and the connecting seat.

[0007] Preferably, the core-pulling block two is provided with a water inlet channel one, a water inlet pipe one and a water outlet channel one, the water inlet pipe one extends into the water outlet channel one, one end of the water inlet pipe one is connected to the water inlet channel one, and the other end of the water inlet pipe one is located in the water outlet channel one.

[0008] Through the above technical scheme, when the bracket body is cast, the external cooling water is pressed into the water inlet channel I, then the cooling water enters the water inlet pipe I, the water inlet pipe I delivers the cooling water to the water outlet channel, and then the cooling water flows out through the water outlet channel I. The water inlet pipe I is arranged to send the cooling water into the water outlet channel I, so that the cooling water can effectively cool the core pulling block II when flowing back.

[0009] Preferably, two sliding grooves I are arranged on the core pulling block II, and a core pulling block III is slidably connected in each of the two sliding grooves I. The core pulling block III is used to form an assembly groove. Two sets of driving mechanisms are arranged on the core pulling block II, and the driving mechanisms are used to control the movement of the core pulling block III into or out of the sliding groove I.

[0010] Through the above technical scheme, when the product is injection molded, the two sets of driving mechanisms drive the two core pulling blocks III to move out of the sliding grooves I, so as to complete the molding of the assembly groove when the bracket body is cast. After the bracket body is cast, the two sets of driving mechanisms drive the two core pulling blocks III to move into the sliding grooves I, thereby canceling the reverse locking structure between the two core pulling blocks III and the two assembly grooves, so that the core pulling block II can smoothly move out of the water outlet channel.

[0011] Preferably, the core pulling block II is provided with a sliding groove II and a sliding groove III, the sliding groove II is located between the sliding groove I and the sliding groove III, and the sliding groove III communicates with the water outlet channel I. The driving mechanism includes a connecting rod slidably connected to the core pulling block II, a sliding block I slidably connected to the sliding groove II, a sliding block II slidably connected to the sliding groove III, and a spring arranged in the sliding groove II. The connecting rod is connected to the core pulling block III, the sliding block I and the sliding block II respectively. The spring is located on the side of the sliding block I away from the sliding block II, and the spring is sleeved on the connecting rod.

[0012] Through the above technical scheme, the cooling of the core pulling block III extending out of the sliding groove I and the bracket body during the molding process is provided. Before the bracket body is injection molded, the external cooling water machine press the cooling water into the water inlet channel I, the water inlet pipe I and the water outlet channel I. The cooling water in the water outlet channel I will press against the sliding block II, drive the sliding block II to slide away from the water inlet pipe I, and drive the connecting rod, the sliding block I and the core pulling block III to move together in the same direction along the respective sliding grooves when the sliding block II moves away from the water inlet pipe I. The core pulling block III moves out of the sliding groove I, and the sliding block I moves away from the water inlet pipe I, which will press the spring to further compress the spring. Finally, the water flow will press the sliding block II against the groove wall of the sliding groove III away from the water inlet pipe I, so that the core pulling block III is in the position of the molding assembly groove. After the bracket body is finished, the external cooling water machine stops pressing the cooling water into the water inlet channel I. Without the water flow pushing the sliding block II, the spring will rebound to drive the sliding block I, the connecting rod, the sliding block II and the core pulling block III to move close to the water inlet pipe I, so that the core pulling block moves into the sliding groove I, thereby canceling the reverse locking structure between the core pulling block III and the assembly groove.

[0018] By using the above technical scheme, the sleeve can prevent the mounting block from being separated from the mounting groove and limit the mounting block. Meanwhile, the sleeve has excellent wear resistance and can prevent the second core-pulling block from wearing the channel on the first core-pulling block and prevent the pouring liquid from flowing between the first core-pulling block and the second core-pulling block.

When the support body 9 is cast, external cooling water passes through the water inlet channel one 21, then the cooling water enters the water inlet pipe one 22, the water inlet pipe one 22 delivers the cooling water into the water outlet channel one 23, and then the cooling water flows out through the water outlet channel one 23.

[0044] With reference to Figure 7 , Figures 11-13 , the core-pulling block two 15 is symmetrically provided with two installation grooves one 28, and an installation block 4 is detachably connected in the installation groove one 28. The installation block 4 comprises a block body one 41 and a block body two 42, the block body one 41 is detachably connected in the installation groove one 28 through bolts. The sleeve 5 is located on the side of the block body one 41 away from the water outlet channel one 23 and is always in contact with the block body one 41, and the sleeve 5 always limits the block body one 41 from being separated from the installation groove one 28.

[0045] With reference to Figures 13-16 , the block body one 41 is provided with an installation groove two 411, and the block body two 42 is threadedly connected in the installation groove two 411. The block body one 41 is provided with a sliding groove one 24, and the side wall of the installation groove close to the water inlet pipe one 22 is provided with a sliding groove two 26. The block body one 41 fills part of the installation groove one 28, and the cavity in the installation groove one 28 not filled by the block body one 41 is a sliding groove three 27.

[0046] With reference to Figures 13-16 , the two sliding grooves one 24 are both slidably connected with a core-pulling block three 25, the core-pulling block three 25 is used for forming an assembly groove 94, and the core-pulling block two 15 is provided with two groups of driving mechanisms 3, the driving mechanisms 3 are used for controlling the core-pulling block three 25 to move into or move out of the sliding groove one 24.

[0047] With reference to Figures 13-16 , the driving mechanism 3 comprises a connecting rod 31 slidably connected on the core-pulling block two 15, a sliding block one 32 slidably connected in the sliding groove two 26, a sliding block two 33 slidably connected in the sliding groove three 27, and a spring 34 installed in the sliding groove two 26. The sliding block one 32 is integrally formed on the connecting rod 31, the top end of the connecting rod 31 is in plug-in cooperation with the core-pulling block three, and the bottom end of the connecting rod 31 is in plug-in cooperation with the sliding block two 33.

[0048] With reference to Figures 13-16, spring 34 is located on the side of the slider one 32 away from the slider two 33, spring 34 is sleeved on the connecting rod 31, one end of spring 34 is in abutment with the block two 42, the other end of spring 34 is in abutment with the slider one 32, the elastic force of spring 34 acts on the slider one 32, spring 34 always drives the slider one 32 to slide towards the sliding groove three 27. In the initial state, spring 34 presses the slider one 32 against the side wall of the sliding groove two 26 close to the sliding groove three 27, at this time, the core pulling block one 13 is located in the sliding groove one 24, and the end of the slider three close to the water inlet pipe one 22 extends into the water outlet channel one 23.

[0049] With reference to Figures 1-16 The casting process of the mold of the application is as follows: First, the mold is closed by the injection machine control, and then the output shafts of the three oil cylinders, i.e., the driving part one 14, the driving part two 16 and the driving part three 62, are elongated to control the movements of the core pulling block one 13, the core pulling block two 15 and the core pulling block four 61 to the predetermined positions, preparing for the molding of the support body 9.

[0050] After the movements of the above-mentioned parts are reset, the external cooling water machine pressurizes the cooling water into the water inlet channel one 21, the water inlet pipe one 22 and the water outlet channel one 23, and the cooling water in the water outlet channel one 23 will press against the slider two 33 to drive the slider two 33 to slide away from the water inlet pipe one 22. When the slider two 33 moves away from the water inlet pipe one 22, the connecting rod 31, the slider one 32 and the core pulling block three 25 will be driven to move together in the same direction along the respective sliding grooves, so that the core pulling block three 25 moves out of the sliding groove one 24. When the slider one 32 moves away from the water inlet pipe one 22, the spring 34 will be squeezed to be further stressed and compressed. Finally, the water flow will press the slider two 33 against the block one 41, so that the core pulling block three 25 is in the position of the molding assembly groove 94.

[0051] Then, the injection machine injects the solution into the mold to complete the molding of the support body 9. During the molding of the support body 9, the cooling water machine will continuously inject cooling water into the core pulling block two 15 to keep the position of the core pulling block three 25 and ensure the cooling of the core pulling block two 15, thereby improving the molding speed of the support body 9.

[0052] After the molding of the support body 9, the external cooling water machine stops injecting cooling water into the core pulling block two 15. Without the thrust of the water flow on the slider two 33, the spring 34 will rebound to drive the slider one 32, the connecting rod 31, the slider two 33 and the core pulling block three 25 to move close to the water inlet pipe one 22, so that the core pulling block moves into the sliding groove one 24, thereby releasing the reverse locking structure of the core pulling block three 25 and the assembly groove 94.

[0053] Then the output shaft of the driving part three 62 is retracted, the driving core block four 61 is driven to move away from the through hole 91, so as to release the undercut structure of the core block four 61 and the through hole 91. Then the mold is opened, and then the output shaft of the driving part two 16 is retracted, so that the driving core block two 15 is driven to slide, so that the core block two 15 slides into the core block one 13, and the undercut structure of the core block two 15 and the support body 9 is released. Then the driving part one 14 drives the core block one 13 to move to release the undercut structure of the driving part one 14 and the connecting seat 92. Then the molded support body 9 can be taken off from the movable mold plate 12, and after the support body 9 is taken off, the mold is closed to cast the next support body 9.

[0054] Of course, the above is only a typical example of the present application, in addition to which the present application can have other various specific embodiments, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
