The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] The present application provides a water chamber front mold slider locking mechanism, which is arranged on a fixed mold and includes:

[0031] A slider body 1, wherein the slider body 1 has a first end 11 and a second end 12 along a first direction, the second end 12 has a molding portion for product molding, a first space 13 is provided near the first end 11, and first through grooves 14 communicating with the first space 13 are respectively provided on both sides of the first space 13 along the second direction; the second direction is perpendicular to the first direction;

[0032] Please refer to Figure 1-Figure 3 As shown, optionally, the fixed mold 2 has a rectangular shape, the first direction is parallel to the long side of the fixed mold 2, and the second direction is parallel to the short side of the fixed mold 2; the forming portion includes a forming rod 15, and the molded product 3 has an annular body near the end of the slider body 1. After the product is formed, the forming rod 15 is inserted into the annular body. Therefore, if demolding is to be achieved, it is necessary to drive the slider body 1 to drive the forming rod 15 to move away from the molded product 3 until it is separated from the annular body for demolding.

[0033] The slider body 1 has a first side wall and a second side wall at both ends along the second direction close to the first end 11, and the first through groove 14 is provided at the bottom of the first side wall and the second side wall. The extension direction of the first through groove 14 is the second direction. Optionally, the cross-section of the first through groove 14 is a rectangle.

[0034] A locking assembly, the locking assembly comprising a driving block 4, the driving block 4 comprising a sliding portion 41 that can slide in the first space 13 along the first direction; locking blocks 5 that can move in the first through groove 14 are provided on both sides of the sliding portion 41, and each locking block 5 is provided with a limit block 6 on the side away from the sliding portion 41, and the limit block 6 is connected to the fixed mold 2;

[0035] Wherein, a positioning groove is provided on the fixed mold 2 at a position corresponding to the limiting block 6 , and the limiting block 6 can be inserted into the positioning groove to complete the connection with the fixed mold 2 .

[0036] The driving block 4 has a first state and a second state. When in the first state, the sliding portion 41 abuts against the end of the locking block 5 away from the limit block 6, and the limit block 6 exerts a first decomposition force on the corresponding locking block 5 along the first direction, from the first end 11 to the second end 12; when in the second state, each locking block 5 is placed in the first through groove 14 close to the end of the limit block 6 and is separated from the limit block 6; Figure 1 As shown, it is a schematic diagram of the driving block 4 in the first state; Figure 2 , which is a schematic diagram of the driving block 4 being in the second state.

[0037] The driving component 7 is arranged on the driving block 4 near the first end 11, and is used to drive the driving block 4 to switch between the first state and the second state, and can drive the driving block 4 to drive the slider body 1 to move along the first direction.

[0038] When in use, the driving block 4 is driven by the driving assembly 7 to drive the slider body 1 to move to the mold closing position, and the locking block 5 is driven to extend and abut against the limit block 6 to complete the locking. After the product is formed, the locking block 5 is driven to separate from the limit block 6, and the slider body 1 is driven to retract to complete the demoulding. Compared with the prior art, the present application completes the mechanical locking of the slider body 1 by abutting against the limit block 6 and the locking block 5. Compared with the prior art, the locking is more stable, and the molding rate of the product is improved.

[0039] In a preferred embodiment, each locking block 5 includes a first locking portion 51 close to the sliding portion 41 and a second locking portion 52 close to the limit block 6, the first locking portion 51 has a first inclined surface 511 close to the first end 11; the sliding portion 41 has second inclined surfaces 411 at both ends along the second direction, the first inclined surface 511 and the corresponding second inclined surface 411 are parallel, when the driving block 4 is in the second state, the first inclined surface 511 is placed on the second inclined surface 411 close to the first end 11 side, when the driving component 7 drives the sliding portion 41 to move along the first direction toward the second end 12 side, the first inclined surface 511 and the second inclined surface 411 move relative to each other, driving the locking block 5 to move along the first through groove 14 toward the limit block 6 side, and the locking block 5 drives the slider body 1 to move toward the molded product 3 side.

[0040] Please refer to Figure 1 and Figure 2 As shown, optionally, the locking block 5 has an octagonal cross section, including a rectangular block arranged in the first through slot 14 and a trapezoidal block arranged on both sides, the two trapezoidal blocks are the first locking portion 51 and the second locking portion 52. When the locking mechanism is as shown in FIG. Figure 1 and Figure 2 When placed as shown, the left side of the first locking portion 51 placed at the top has the first inclined surface 511, the extended line of the normal of the first inclined surface 511 forms a first angle with the first direction, and its opening faces the second end 12; the extended line of the normal of the first inclined surface 511 on the left side of the first locking portion 51 placed at the bottom forms a second angle with the first direction, and its opening faces the first end 11.

[0041] When the driving block 4 is in the second state, the first inclined surface 511 is placed on the left side of the second inclined surface 411. When the driving component 7 drives the driving block 4 to move to the right, the first inclined surface 511 and the second inclined surface 411 are in contact and a force is applied to the first inclined surface 511. The force is decomposed into a decomposed force pointing to the second end 12 along the first direction. The decomposed force drives the locking block 5 to drive the slider body 1 to move to the right; the force is also decomposed into a decomposed force pointing to the limit block 6 along the second direction. The decomposed force drives the locking block 5 to move to both sides along the first through groove 14 until it switches to the first state.

[0042] In a preferred embodiment, the sliding portion 41 also includes a first abutting portion 42 connected to the lowest end of the second inclined surface 411, and a second abutting portion 43 connected to the highest end of the second inclined surface 411. When the driving block 4 is in the first state, the first abutting portion 42 abuts against the inner wall of the first space 13 near the second end 12, and a first gap is formed between the second abutting portion 43 near the first end 11 and the inner wall of the first space 13; when the driving block 4 is in the second state, the second abutting portion 43 abuts against the inner wall of the first space 13, the first locking portion 51 is tightly attached to the outer wall of the first abutting portion 42 along the second direction, and the second locking portion 43 is placed in the first through groove 14.

[0043] Among them, Figure 1 and Figure 2 As shown, the first abutting portion 42 is arranged on the right side of the first inclined surface 511, and its cross section is a rectangular parallelepiped. The surface connecting the first abutting portion 42 and the first inclined surface 511 is a first end surface, and the first end surface is a plane and parallel to the first direction. The locking block 5 has a second end surface connected to the first inclined surface 511 on the side close to the second end 12 of the first inclined surface 511, and the second end surface is parallel to the first end surface. When in the second state, the first inclined surface 511 is in close contact with the second inclined surface 411, and the first end surface is in close contact with the second end surface. The second abutting portion 43 is arranged on the left side of the second inclined surface 411, and has the same structure as the first abutting portion 42. Along the second direction, the width of the second abutting portion 43 is greater than the width of the first abutting portion 42.

[0044] In a preferred embodiment, the second locking portion 52 has a third inclined surface 521 near the first end 11, and each of the limit blocks 6 has a fourth inclined surface 61 parallel to the third inclined surface 521. When the driving block 4 is in the first state, the third inclined surface 521 abuts against the corresponding fourth inclined surface 61, and the fourth inclined surface 61 is placed on the side of the third inclined surface 521 away from the second end 12, and the fourth inclined surface 61 applies the first decomposition force on the third inclined surface 521.

[0045] Please refer to Figure 1 and Figure 2 The third inclined surface 521 is arranged on the left side of the second locking portion 52, and the direction of the normal extension line of the third inclined surface 521 placed at the top forms a third angle with the first direction, and the opening of the third angle is toward the first end 11 side, and the direction of the normal extension line of the third inclined surface 521 placed at the bottom forms a fourth angle with the first direction, and the opening of the fourth angle is toward the second end 12 side.

[0046] The locking block 5 also has a third end face connected to the third inclined surface 521, and the third end face is parallel to the second end face. The limit block 6 also has a fourth end face connected to the fourth inclined surface 61, and the fourth end face is parallel to the third end face. The second abutment portion 43 has fifth end faces at both ends along the second direction, and the fifth end face is parallel to the second end face. When the driving block 4 is in the first state, the third inclined surface 521 is in close contact with the fourth inclined surface 61, the third end surface and the fourth end surface are in close contact, and the second end surface is in close contact with the fifth end surface. The fourth inclined surface 61 applies an oblique force on the third inclined surface 521, and the force is decomposed into the first decomposition force and the second decomposition force. The first decomposition force prevents the locking block 5 from moving to the left, thereby achieving the locking of the slider body 1. The second decomposition force is directed along the second direction to the end of the limit block 6, but the second end surface of the locking block 5 is in close contact with the fifth end surface of the second abutment portion 43, so the second abutment portion 43 prevents the locking block 5 from moving away from the limit block 6.

[0047] In a preferred embodiment, when the driving component 7 drives the driving block 4 to switch from the first state to the second state, it drives the sliding portion 41 to move toward the first end 11 side in the first space, and the fourth inclined surface 61 applies a second decomposition force along the second direction close to the sliding portion 41 side on the locking block 5, driving the first locking portion 51 to move along the first through groove 14 toward the first abutment portion 42 side until the second locking portion 52 disengages from the limit block 6.

[0048] Among them, when in the first state, the second abutment portion 43 blocks the locking block 5 from moving away from the limit block 6 side, but when the product is formed, the driving component 7 drives the driving block 4 to move away from the molded product 3 side, and the second abutment portion 43 gradually disengages from the second end face of the locking block 5. When the first inclined surface 511 and the second inclined surface 411 are in contact, the locking block 5 can move along the second inclined surface 411 away from the limit block 6 end, so that the locking block 5 can be disengaged from the limit block 6.

[0049] In a preferred embodiment, when in the second state, the second abutment portion 43 abuts against the inner wall of the first space 13, and the driving assembly 7 continues to drive the second abutment portion 43 to drive the slider body 1 to move away from the molded product 3 to complete demolding.

[0050] Among them, when switching from the first state to the second state, the second abutment portion 43 moves in the first gap until it abuts against the inner wall of the first space 13. At this time, the driving block 4 switches to the second state. When the driving component 7 continues to drive the sliding portion 41 to move to the left, it can drive the sliding body 1 to move.

[0051] In a preferred embodiment, blocking blocks 81 are provided on both sides of the slider body 1 along the second direction, and the blocking blocks 81 are connected to the fixed mold 2. The blocking blocks 81 are arranged on the corresponding limit block 6 close to the first end 11. The blocking blocks 81 are used to block the locking block 5 from extending from the first through groove 14 away from the first space 13 end when the driving assembly 7 continues to drive the slider body 1 to move away from the molded product 3 after the driving block 4 switches to the second state.

[0052] Please refer to Figure 5-Figure 7 As shown, a fixing block 82 is further provided at the bottom of the blocking block 81. Optionally, the fixing block 82 and the blocking block 81 are integrally formed in an L shape. Both fixing blocks 82 are placed at the bottom end of the sliding body 1, and the fixing blocks 82 are connected to the fixed mold 2 by bolts. When the demoulding is completed and the first state is switched, the driving block 4 applies a first decomposition force to the right and a second decomposition force to both sides along the second direction to the locking block 5. The first decomposition force drives the locking block 5 to drive the slider body 1 to move to the right. Although there is a second decomposition force, the locking block 5 cannot move to both sides due to the obstruction of the blocking block 81 until the third inclined surface 521 is placed on the right side of the fourth inclined surface 61. The locking block 5 moves to both sides along the fourth inclined surface 61 of the limit block 6 and switches to the first state.

[0054] Please refer to Figure 4 As shown, the slider body 1 is provided with a T-shaped slot near the first end 11 , and the T-shaped slot forms the first space 13 and the second through slot 17 .

[0055] In a preferred embodiment, a first guide assembly is provided on the fixed mold 2, and the first guide assembly provides guidance for the slider body to move along the first direction.

[0056] Please refer to Figure 3 , Figure 5 and Figure 6 As shown, the first guide assembly includes first guide blocks 91 arranged on both sides of the slider body 1 along the second direction, the extension direction of the first guide blocks 91 is the first direction, each of the first guide blocks 91 is connected to the fixed mold 2 by a bolt, and the slider body 1 can move along the first direction between the two first guide blocks 91, thereby improving the stability of the movement.

[0057] In a preferred embodiment, the driving assembly 7 includes a hydraulic cylinder, and the hydraulic cylinder includes a telescopic rod connected to the driving block. The fixed mold 2 is provided with a second guide assembly 92, and the second guide assembly 92 provides guidance for the telescopic rod to extend and retract along the first direction.
