DETAILED DESCRIPTION

[0027] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the utility model.

[0028] Please refer to Figures 1 to 5The utility model discloses a mould of external mould closing sequence pipe and control structure, which comprises pipe and control components 3 installed on female mould 1 and male mould 2 respectively.

[0029] Please see Figures 1 to 2 Female mould 1 comprises female mould fixed plate 11, female mould runner plate 12 fixedly connected with female mould fixed plate 11, material pushing plate 13 arranged below female mould runner plate 12 and female mould plate 14. Female mould fixed plate 11 is used for bearing female mould runner plate 12, material pushing plate 13 and female mould plate 14, so that female mould runner plate 12, material pushing plate 13 and female mould plate 14 are in a horizontal state. A guide column 15 is arranged in female mould runner plate 12. One end of the guide column 15 is fixedly connected with female mould runner plate 12, and the other end extends vertically downward and penetrates material pushing plate 13 and female mould plate 14. Material pushing plate 13 and female mould plate 14 move along the guide column 15.

[0030] Material pushing plate 13 and female mould plate 14 can be separated from female mould runner plate 12. Specifically, female mould plate 14 and material pushing plate 13 are sleeved with the guide column 15 and move synchronously with female mould runner plate 12. When the mould is closed, female mould plate 14 first contacts male mould 2 and closes with male mould 2, material pushing plate 13 then closes with female mould plate 14, and female mould runner plate 12 closes with material pushing plate 13.

[0031] Please see Figures 1 to 2 Male mould 2 comprises male mould fixed plate 21, mould foot plate 22 fixedly connected with male mould fixed plate 21 and male mould plate 23. Male mould fixed plate 21 is used for bearing mould foot plate 22 and male mould plate 23, so that mould foot plate 22 and male mould plate 23 are in a horizontal state. Male mould 2 further comprises positioning hole 24, which penetrates male mould fixed plate 21, mould foot plate 22 and male mould plate 23 in sequence and corresponds to the guide column 15. The guide column 15 can enter the positioning hole 24.

[0032] Please see Figures 3 to 5 The number of pipe and control components 3 changes according to requirements. In the embodiment, the number of pipe and control components 3 is four, which are installed on the outer side surfaces of female mould 1 and male mould 2 respectively. Pipe and control components 3 comprise fixing block 31 and locking block 32 installed on female mould 1 and locking part 33 installed on male mould 2. Fixing block 31 is fixed to the side surface of female mould runner plate 12 and is fixedly installed with fixing shaft 34. The top of fixing shaft 34 is fixedly connected with fixing block 31, and the bottom thereof extends vertically downward. The extension length changes according to requirements. Spring 35 is sleeved with fixing shaft 34. The two ends of spring 35 are fixed with the two ends of fixing shaft 34. The end of fixing shaft 34 is installed with pushing rod 36. The top of pushing rod 36 is fixedly connected with fixing shaft 34, and the bottom thereof extends vertically downward. The end of pushing rod 36 is provided with pushing block 37. One side of pushing block 37 is fixedly connected with pushing rod 36, and the other side thereof extends outward. The top of pushing block 37 forms an inclined downward slope.

[0033] The locking block 32 is installed on the side surface of the mother template 14, located below the fixing block 31 and the fixing shaft 34. The locking block 32 has a first through hole 321 and a second through hole 322. Both the first through hole 321 and the second through hole 322 penetrate the upper and lower surfaces of the locking block 32. The opposite sides of the first through hole 321 and the second through hole 322 are connected to each other to form a passage space 323. Preferably, the locking block 32 has a locking groove 324 formed by an inward inclination from the upper surface. The locking groove 324 is located between the first through hole 321 and the second through hole 322 and is provided on both sides of the passage space 323. The fixing shaft 34 and the lever 36 can pass through the first through hole 321, so that the lever 37 can enter or exit the passage space 323.

[0034] The locking part 33 includes a locking fixing block 331, a locking rod 332 installed in the locking fixing block 331, and an elastic member 333 for pushing the locking rod 332. The locking fixing block 331 is installed on the side surface of the male template 23 and is located below the locking block 32. It has a third through hole 334 and a fourth through hole 335 that penetrate its upper and lower surfaces. The third through hole 334 and the fourth through hole 335 correspond to the first through hole 321 and the second through hole 322. The locking rod 332 is installed in the fourth through hole 335. The locking part 33 is provided with a limiting shaft 336. The limiting shaft 336 penetrates the locking fixing block 331 and extends into the fourth through hole 335, penetrating the bottom of the locking rod 332. The locking rod 332 rotates within the fourth through hole 335 with the limiting shaft 336 as the center. Furthermore, a locking protrusion 337 is formed on the top of the locking rod 332. The locking protrusion 337 extends toward the fixing shaft 34 and can extend into or out of the locking groove 324.

[0035] One end of the elastic element 333 abuts against the locking block 331, and the other end abuts against the side of the locking rod 332.

[0036] In the mold of this utility model with an external mold closing sequence control structure, when the female mold 1 and male mold 2 are closed, the guide post 15 enters the positioning hole 24, and the female mold plate 14 moves towards the male mold plate 23. At the same time, the fixed shaft 34 and the lever 36 pass through the first through hole 321 in sequence. When they move to a certain extent, the female mold plate 14 and male mold plate 23 cannot be completely closed due to precision, tolerance, or other reasons. The spring 35 presses against the upper surface of the locking block 32, and its elastic force pushes the female mold plate 14 to continue moving towards the male mold plate 23, completing the mold closing of the female mold plate 14 and male mold plate 23. At this time, the lock... The fixed rod 332 passes through the second through hole 322, and the elastic element 333 pushes the locking rod 332 to move, so that the locking protrusion 337 enters the locking groove 324, locking the female template 14 and the male template 23, opening the female mold 1 and the male mold 2, and the fixed shaft 34 and the lever 36 move upward accordingly. The female mold flow channel plate 12 and the material ejector plate 13 open the mold first, and the female template 14 and the male template 23 remain locked. After continuous mold opening, the lever 37 passes through the passage space 323, squeezing the locking protrusion 337 out of the locking groove 324, and the female template 14 and the male template 23 complete the mold opening.

[0037] This utility model is a mold with an external mold closing sequence control structure, which has the feature of improving production efficiency. By applying pressure to the locking block through a spring, the female mold plate and the male mold plate close first. After the mold is closed, the locking protrusion enters the locking groove, locking the female mold plate and the male mold plate. This allows the female mold plate and the male mold plate to open last, avoiding the losses caused by using nylon openers and closing devices and improving production efficiency.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
