It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0047] like Figure 1 , Figure 3As shown, the present invention provides a secondary demolding mechanism, which includes a mold core lifting seat 1, an upper mold lifting seat 2, a first lifting component 3 and a second lifting component 4; the first side of the mold core lifting seat 1 is used to install the mold core 5, and the other opposite second side of the mold core lifting seat 1 is provided with a first inclined surface 121, and the first inclined surface 121 is inclined toward the first side; the upper mold lifting seat 2 is arranged on the side of the mold core lifting seat 1 away from the mold core 5, and the side surface of the upper mold lifting seat 2 is provided with a second inclined surface 21, and the second inclined surface 21 abuts against the first inclined surface 121; the first lifting component 3 is connected to the mold core lifting seat 1 for lifting the mold core 5; the second lifting component 4 is connected to the upper mold lifting seat 2 for lifting the upper mold. In this embodiment, the upper mold lifting seat 2 and the first lifting component 3 constitute the lifting structure of the upper mold, the core lifting seat 1 and the second lifting component 4 constitute the lifting structure of the core 5, and at the same time, a first inclined surface 121 is provided on the second side of the core lifting seat 1, and a second inclined surface 21 is provided on the first side of the upper mold lifting seat 2 facing the core lifting seat 1. In this way, in this embodiment, the first lifting component 3, the second lifting component 4, the first inclined surface 121 and the second inclined surface 21 can be used to complete multiple mold closing or demolding actions, including upper mold lifting, core 5 lifting, upper mold and core 5 synchronous lifting, and can complete secondary lifting, and complete complex and various actions with a simple structure.

[0048] The first inclined surface 121 is inclined toward the first side, and it can be considered that the first inclined surface 121 is rotated from a vertical state and the normal line of the first inclined surface 121 is rotated toward the first side of the mold core lifting seat 1, thereby obtaining the first inclined surface 121 inclined toward the first side. For the first inclined surface 121, the normal line of the second inclined surface 21 is rotated from a vertical state toward the first side of the mold core lifting seat 1, thereby obtaining the second inclined surface 21 inclined toward the first side. In some specific embodiments, the first inclined surface 121 and the second inclined surface 21 are parallel to each other.

[0049] In some embodiments, Figure 1 As shown, the mold core lifting seat 1 also includes a base 11 and a sliding seat 12, the sliding seat 12 is slidably disposed on the base 11, and the mold core 5 is connected to the sliding seat 12. In this embodiment, the mold core 5 is connected to the sliding seat 12 and moves with the sliding seat 12. During installation, the sliding seat 12 and the base 11 are slidably matched, and the mold core 5 can be smoothly and accurately moved to a predetermined position, thereby improving the installation accuracy.

[0050] The first inclined surface 121 is specifically disposed on the second side of the sliding seat 12 .

[0051] In some embodiments, Figures 4 to 6As shown, the mold core lifting seat 1 also includes a locking assembly 13, a part of the locking assembly 13 is connected to the upper mold, a part of the locking assembly 13 is connected to the base 11, another part of the locking assembly 13 is connected to the sliding seat 12, and the locking assembly 13 is also connected to the upper mold, and is used to lock the base 11, the sliding seat 12 and the upper mold together. In this embodiment, the upper mold, the base 11 and the sliding seat 12 are locked together by using the locking assembly 13, and assembled in a locked form. In the case of densely packed parts or when it is inconvenient to use tools, the locking assembly 13 in this embodiment has a faster assembly speed.

[0052] Specifically, if Figure 4 As shown, it is connected to the guide block 6 on the upper mold, and the guide block 6 can slide up and down on the upper mold. The locking assembly 13 locks the guide block 6, the base 11 and the sliding seat 12 together, so that the mold core lifting seat 1 can move with the guide hole, which is convenient for the mold core lifting seat 1 to close and demold.

[0053] Guide blocks 6 are provided on both sides of the base 11 . Similarly, in this embodiment, two sets of locking assemblies 13 are provided, that is, the locking assemblies 13 and the guide blocks 6 are provided in a one-to-one correspondence.

[0054] Regarding the locking component 13, in some embodiments, the locking component 13 is a screw or a pin, and the screw sequentially connects the base 11, the sliding seat 12 and the upper mold, thereby locking the base 11, the sliding seat 12 and the upper mold together.

[0055] In some embodiments of the locking assembly 13, such as Figures 4 to 6 As shown, the locking assembly 13 includes a locking block 131 and a locking screw 132 .

[0056] A locking groove 122 is provided on the side wall of the mold core lifting seat 1 facing the upper mold, specifically, a locking groove 122 is provided on the side wall of the sliding seat 12 facing the upper mold, and the locking groove 122 penetrates the surface of the base 11. A mounting position for disassembling and assembling a locking block 131 is provided at the first end of the locking groove 122, and a locking position is provided at the second end of the locking groove 122. A limiting groove 61 for limiting the position of the locking block 131 is provided on the side wall of the upper mold facing the locking groove 122, specifically, a limiting groove 61 is provided on the side wall of the guide hole facing the locking groove 122. A locking screw 132 is provided at a position on the base 11 corresponding to the limiting groove 61, and the locking screw 132 extends into the locking groove 122. A long hole is provided on the locking block 131, and the length direction of the long hole intersects with the sliding direction of the sliding seat 12, and the locking block 131 is sleeved on the locking screw 132. The sliding seat 12 slides on the base 11, and when the mounting position moves to a position corresponding to the limiting groove 61, the locking block 131 can be disassembled and assembled; when the locking position moves to a position corresponding to the limiting groove 61, the locking block 131 locks the upper mold and the sliding seat 12, and the locking screw 132 locks the sliding seat 12 and the base 11.

[0057] In this embodiment, during the initial installation, the sliding seat 12 is installed on the base 11, and the sliding seat 12 is moved so that the installation position of the locking groove 122 is aligned with the installation position of the locking screw 132. The locking block 131 is installed in the installation position, the locking screw 132 is installed on the base 11, and the locking screw 132 extends into the locking groove 122, and the locking screw 132 also extends into the long hole of the locking block 131. The limiting groove 61 on the upper mold is aligned with the installation position, that is, the limiting groove 61 on the guide block 6 mentioned above is aligned with the installation position.

[0058] At this time, the sliding seat 12 is moved, the locking groove 122 moves with the sliding seat 12, and the locking position also moves to the position corresponding to the limiting groove 61. As for the locking block 131, as the locking groove 122 moves, it gradually extends into the limiting groove 61 until a part of the locking block 131 is located at the locking position and the other part is embedded in the limiting groove 61, thereby achieving the locking of the upper mold (or the guide seat), the base 11 and the sliding seat 12. The locking assembly 13 is used to assemble the upper mold (or the guide seat), the base 11 and the sliding seat 12 in a locked form, which can reduce the use of fasteners, reduce the use of assembly tools, and speed up the disassembly and assembly speed.

[0059] For the locking groove 122, the shape of the mounting position at the first end thereof is adapted to the shape of the locking block 131, or the outline of the mounting position may be larger than the outline of the locking block 131, so that during installation, the mounting position can completely accommodate the locking block 131, and the locking position at the second end of the locking groove 122 can accommodate a part of the locking block 131, and the part of the locking block 131 that exceeds the locking position is the locking portion. The shape of the limiting groove 61 is adapted to the shape of the locking portion, or the outline of the limiting groove 61 may be larger than the outline of the locking portion, so that when the locking block 131 is in the so-called position, the locking portion can be accommodated by the hook limiting groove 61, thereby achieving locking.

[0060] In addition, a first guide surface 123 is provided in the locking groove 122, and the locking block 131 is guided from the installation position to the locking position by the first guide surface 123. Similarly, in order to improve the guiding effect, the locking block 131 is also provided with a guiding inclined surface corresponding to the first guide surface 123. Furthermore, a second guide surface 62 is also provided in the limiting groove 61, and the locking portion of the locking block 131 extends into the limiting groove 61.

[0061] In some embodiments, Figure 6As shown, the base 11 is provided with a first guide groove 1111, and the guiding direction of the first guide groove 1111 intersects with the sliding direction of the sliding seat 12. More specifically, the guiding direction of the first guide groove 1111 is perpendicular to the sliding direction of the sliding seat 12. The locking block 131 is slidably matched with the first guide groove 1111. Thus, in this embodiment, when the locking block 131 moves between the limiting groove 61 and the installation position, it can move smoothly with the help of the first guide groove 1111, thereby preventing the locking block 131 from rotating and flipping.

[0062] In some embodiments, Figure 6 As shown, the base 11 is further provided with a second guide groove 1112 , and the sliding seat 12 is slidably matched with the second guide groove 1112 , and the second guide groove 1112 is provided to guide the sliding seat 12 to move smoothly.

[0063] In some embodiments, Figures 4 to 6 As shown, the mold core lifting seat 1 further includes a sleeve rod 14, and the base 11 includes a bottom plate 111 and a side plate 112 located on a first side of the bottom plate 111. One end of the sleeve rod 14 is connected to the sliding seat 12, and the other end of the sleeve rod 14 passes through the side plate 112 to be sleeved with the mold core 5. In this embodiment, the mold core 5 is installed in the form of the sleeve rod 14, and the sleeve connection between the rod and the mold core 5 improves the installation accuracy of the mold core 5.

[0064] In some embodiments, Figure 1 , Figure 2 As shown, the secondary demoulding mechanism further includes a guide rod 7. A guide hole is provided on the mold core lifting seat 1, and the axis of the guide hole is parallel to the first inclined surface 121. Specifically, the guide hole is provided on the sliding seat 12. The guide rod 7 is slidably provided in the guide hole. In this embodiment, the movement of the mold core lifting seat 1 is guided by providing the guide rod 7.

[0065] In some embodiments, the mold core lifting seat 1 further includes a push rod assembly (not shown in the figure), which is disposed on the first side of the mold core lifting seat 1. The push rod assembly is provided with a push rod, and the push rod is connected to the sliding seat 12. In this embodiment, the second inclined surface 21 on the upper mold lifting seat 2 presses the first inclined surface 121 on the sliding seat 12, thereby forcing the sliding seat 12 to move in the direction of the first side, and the push rod assembly pushes the sliding seat 12 to move in the direction of the second side, thereby realizing any movement of the sliding seat 12 on the base 11.

[0066] Specifically, a mounting hole is provided on one side of the side plate 112 away from the bottom plate 111 , a through hole is provided in the mounting hole and penetrates the side plate 112 , the push rod assembly is disposed in the mounting hole, and the push rod on the push rod assembly passes through the through hole and abuts against the sliding seat 12 .

[0067] The push rod assembly can be an electric push rod assembly, a pneumatic push rod, or a hydraulic push rod.

[0068] In some embodiments, the upper mold lifting seat 2 is provided with a first abutting surface, and the first abutting surface faces downward. The mold core lifting seat 1 is provided with a second abutting surface adapted to the first abutting surface. When the upper mold lifting seat 2 moves downward, it presses the mold core lifting seat 1 to move downward, so that the mold core lifting seat 1 is molded.

[0069] Specifically, the second abutting surface is located on the upper surface of the bottom plate 111 .

[0070] In some embodiments, Figure 1 As shown, the demoulding mechanism further includes a linkage mechanism 8, a part of which is connected to the mold core 5, and another part of which is connected to the first lifting assembly 3. In this way, when the first lifting assembly 3 lifts the mold core lifting seat 1, the first lifting assembly 3 also lifts the linkage mechanism 8 synchronously, and the linkage mechanism 8 and the mold core lifting seat 1 synchronously lift the mold core 5, so that various parts of the mold core 5 can be lifted and lowered synchronously.

[0071] The linkage mechanism 8 is simply a structure that can be connected to the mold core 5. The linkage mechanism 8 and the mold core lifting seat 1 are both connected to the first lifting component 3, so that the linkage mechanism 8 and the mold core lifting seat 1 move synchronously, and there is linkage between the two.
