[0034] When the vertical stroke mechanism of this embodiment is in use, the upper mold 1 is first brought into contact with the lower mold 2 to achieve mold closing, so that the upper runner 11 corresponds to the lower runner 21, and the upper groove 12 corresponds to the lower groove 22, and then the second movable plate 6 is moved downward in the vertical direction. During this process, the first movable plate 5 remains in position, and at this time, a plurality of the inclined grooves move downward, and a plurality of inclined blocks pass through the inclined grooves in sequence, thereby driving the transverse movable plate 3 and the mold core shaft 4 to move to the position between the upper groove 12 and the lower groove 22, and pouring the castable into the lower runner 21 and the lower runner 21 to obtain a product of an automotive connector component; the second movable plate 6 is moved upward in the vertical direction, and the inclined groove moves upward at this time, and a plurality of inclined blocks on the second movable block are continuously inserted into a plurality of inclined grooves on the transverse movable plate 3 from the upper end to the lower end in turn, thereby driving the transverse movable plate 3 and the mold core shaft 4 away from the position between the upper groove 12 and the lower groove 22, and then the upper mold 1 is opened and separated from the lower mold 2. The whole process realizes the horizontal insertion and disengagement of the mold core shaft 4 to ensure the coaxial accuracy of the inner hole of the product and improve the product quality.

[0035] like Figure 2-4 As shown, the inclined groove of the second movable plate 6 includes a first guide groove 61, a second guide groove 62, a third guide groove 63, a fourth guide groove 64 and a fifth guide groove 65, and the inclined block includes a first guide block 31, a second guide block 32, a third guide block 33, a fourth guide block 34 and a fifth guide block 35. During the movement of the lateral moving portion toward the upper mold 1 and the lower mold 2, the first guide block 31, the second guide block 32, the third guide block 33, the fourth guide block 34 and the fifth guide block 35 are respectively inserted into and passed through the first guide groove 61, the second guide groove 62, the third guide block 33, the fourth guide block 34 and the fifth guide block 35 in sequence. Guide groove 63, the fourth guide groove 64 and the fifth guide groove 65, until the mold core shaft 4 completely enters into the upper shape groove 12 and the lower shape groove 22; when the mold core shaft 4 needs to be pulled out, the second movable plate 6 is moved upward, and then the fifth guide block 35, the fourth guide block 34, the third guide block 33, the second guide block 32 and the first guide block 31 pass through the fifth guide groove 65, the fourth guide groove 64, the third guide groove 63, the second guide groove 62 and the first guide groove 61 respectively, and the mold core shaft 4 is completely out of the upper shape groove 12 and the lower shape groove 22.

[0036] like Figure 2 , Figure 6As shown, the number of the first movable plate 5 and the second movable plate 6 are respectively two, and the two second movable plates 6 are respectively arranged on both sides of the transverse movable plate 3, and the inclined grooves of the two second movable plates 6 respectively correspond to the inclined blocks on both sides of the transverse movable plate 3. When the two second movable plates 6 move up and down, the left and right sides of the transverse movable plate 3 can smoothly drive the left and right sides of the mold core shaft 4 to move synchronously, thereby avoiding the occurrence of defective products due to the inconsistent positions of the left and right ends of the mold core shaft 4 at the lower groove 22.

[0037] like Figure 5 As shown, an upper transverse retaining groove 14 is provided on the side of the lower end face of the upper mold 1 close to the transverse moving part, and a lower transverse retaining groove 24 is provided on the side of the upper end face of the lower mold 2 close to the transverse east. When the upper mold 1 and the lower mold 2 are closed, the upper transverse retaining groove 14 and the lower transverse retaining groove 24 form a limiting positioning area for limiting the transverse moving part from continuing to move to the left, and during the horizontal movement of the transverse moving part, it can be ensured that the mold core shaft 4 can be accurately inserted into the area between the upper shape groove 12 and the lower shape groove 22.

[0038] like Figure 2 As shown, the upper groove 12 is arranged on the lower end surface of the upper mold 1, and at least one positioning block 13 is also arranged on the lower end surface of the upper mold 1, and the lower groove 22 is arranged on the upper end surface of the lower mold 2, and at least one positioning groove 23 is also arranged on the upper end surface of the lower mold 2. In the process of moving the upper mold 1 to the lower mold 2 for mold closing, the positioning block 13 is aligned with the positioning groove 23 and snapped into it, so that the upper mold 1 and the lower mold 2 are positioned. In this embodiment, four positioning grooves 23 are arranged, which are respectively located at the four corners of the upper end surface of the lower mold 2, and four positioning blocks 13 are also arranged, which are respectively located at the four corners of the lower end surface of the upper mold 1. The four positioning blocks 13 are matched with the four positioning grooves 23 to realize the four-corner positioning of the upper mold 1 and the lower mold 2, ensuring that the four corners of the upper groove 12 and the lower groove 22 can accurately correspond to each other, so as to improve the product yield.

[0039] like Figure 6-9 As shown, the lower mold 2 is provided with a plurality of ejection holes 25, and the ejection holes 25 are arranged at the position of the lower groove 22. A plurality of ejector pins 7 corresponding to the positions of the ejection holes 25 are provided below the lower mold 2. When the mold core shaft 4 is completely pulled out of the product and the mold is opened, the ejector pins 7 are moved upward and inserted into the ejection holes 25 to eject the product located in the lower groove 22 upward, thereby realizing the product's detachment process from the lower groove 22.

[0040] like Fig. 9As shown, the transverse movable plate 3 is provided with an inclined surface 36, and the inclined surface 36 is arranged on the side away from the mold core axis 4.

In this embodiment, the lower pressure plate 8 and the second movable block are fixedly connected. When the second movable block and the lower pressure plate 8 move vertically downward together, the inclined surface 36 is pressed by the pressing inclined surface 81, so that the transverse movable plate 3 is forced to move toward the upper mold 1 and the lower mold 2, thereby enhancing the movement stability of the transverse movable plate 3.

[0041] like Fig.10 and Fig.11 As shown, the working principle is as follows:

[0042] Step ①: The leftmost part of the mold core shaft 4 is located in or completely away from the restricted positioning area of ​​the transverse moving part formed by the upper transverse groove 14 and the lower transverse groove 24. At this time, the rightmost end of the transverse moving block is located at point p1, and the first guide block 31 and the second guide block 32 are located in the first guide groove 61 and the second guide groove 62. The distance between the rightmost end of the transverse moving block and the rightmost end of the second moving block is H1.

[0043] Step ②: The second movable plate 6 moves downward so that the third guide block 33 is about to be inserted into the third guide groove 63, and the transverse movable plate 3 and the mold core shaft 4 move a certain distance to the left;

[0044] Step ③: The second movable plate 6 moves downward so that the third guide block 33 is completely inserted into the third guide groove 63, and the transverse movable plate 3 and the mold core shaft 4 continue to move a certain distance to the left;

[0045] Step ④: The fourth guide block 34 is inserted into the fourth guide groove 64, and the fifth guide block 35 is about to be inserted into the fifth guide groove 65. At this time, the transverse moving plate 3 is located in the restricted positioning area of ​​the transverse moving part formed by the upper transverse groove 14 and the lower transverse groove 24, and the mold core shaft 4 is located between the upper shape groove 12 and the lower shape groove 22. The rightmost end of the transverse moving block is located at point p2, and the distance between the rightmost end of the transverse moving block and the rightmost end of the second moving block is H2.

[0046] The process of steps ①-④ is completed. When the second movable plate 6 moves vertically downward, it drives the mold core shaft 4 to move to the left and is clamped into the upper mold 1 and the lower mold 2, ensuring that the mold core shaft 4 does not rotate or deviate, thereby ensuring the coaxiality of the produced product.

[0047] Step ⑤: The second movable plate 6 moves upward so that the third guide block 33 is completely inserted into the third guide groove 63, the fourth guide block 34 is inserted into the second guide groove 62, and the transverse movable plate 3 and the mold core shaft 4 move a certain distance to the right;

[0048] Step ⑥: The second movable plate 6 continues to move upward so that the fifth guide block 35 is inserted into the first guide groove 61, and the transverse movable plate 3 and the mold core shaft 4 continue to move a certain distance to the left;

[0049] Step ⑦: The leftmost part of the mold core shaft 4 is located in or completely away from the restricted positioning area of ​​the transverse moving part formed by the upper transverse groove 14 and the lower transverse groove 24. At this time, the rightmost end of the transverse moving block is located at point p1, and the first guide block 31 and the second guide block 32 are located in the first guide groove 61 and the second guide groove 62.

[0050] The process of steps ⑤-⑦ realizes the mold core shaft 4 being pulled away from the product and away from the area of ​​the upper mold 1 and the lower mold 2, and the ejector pin 7 is moved upward and inserted into the ejection hole 25 to eject the product located in the lower groove 22 upward, during the disengagement process of the lower groove 22.

[0051] The production process of a product is realized through steps ①-⑦, and the coaxiality and accuracy of multiple products produced can be guaranteed by repeating the above steps.
