Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a tunnel slider structure. Background Art

[0002] An injection mold is a commonly used mold. Usually, a corresponding mold cavity is set according to the specific shape of a sample. By injecting molten plastic material into the mold cavity and then cooling and forming, the sample can be obtained. The injection mold has the advantages of fast production speed, high efficiency, and automation of operation, and is a commonly used component in plastic processing production.

[0003] However, in the existing injection mold, the junction box is usually directly installed on the side wall of the mold. The installation and disassembly of the junction box are inconvenient, and the junction box is in direct contact with the injection mold. The too high temperature of the mold is likely to damage the junction box, affecting the service life of the junction box. And when the injection mold needs to be repaired or maintained, usually the junction box needs to be disassembled from the injection mold first. Frequent disassembly of the junction box is also likely to cause damage, reducing the service life.

[0004] Among them, the utility model with the application number CN202322876738.1 relates to an injection mold, including a top mold, a bottom mold, an insert and a junction box. The bottom mold and the top mold are arranged parallel to each other, and the bottom mold and the top mold are in movable abutment. A cavity is arranged between the bottom mold and the top mold. The first surface of the insert is detachably connected to the outer side wall of one of the top mold and the bottom mold, and the junction box is detachably connected to the second surface of the insert. By providing the insert, the insert can serve as an isolation layer between the junction box and the outer side wall of the top mold or the bottom mold, avoiding the direct contact between the junction box and the top mold or the bottom mold, thus being beneficial to preventing the temperature of the top mold or the bottom mold from being directly transmitted to the junction box, being beneficial to avoiding too high a temperature of the junction box, and playing a protective role for the junction box. At the same time, the junction box can be disassembled and installed by detaching the insert from the top mold or the bottom mold, avoiding directly disassembling and installing the junction box, being beneficial to further protecting the junction box, thus being beneficial to improving the service life of the junction box and improving production efficiency.

[0005] Most of the existing slider structures are provided with a mold line structure for the movement of the first slider rod. This structure requires relatively high design requirements for the mold core. After injection molding, it is easy to cause low precision of the formed product, and it is not easy for the product to be separated from the mold cavity of the mold core during demolding.

The movable mold module 3 includes a panel 31, a movable mold plate 32, and an upper mold core 33 installed on the movable mold plate 32.

[0046] The fixed mold module 1 includes a fixed mold plate 11 and a lower mold core 12 disposed on the lower surface of the fixed mold plate 11. The lower mold core 12 is formed with a lower mold cavity 26. The fixed mold plate 11 is provided with a first slider assembly 10 for demolding. The first slider assembly 10 includes a first slider block 13 that moves horizontally along the fixed mold plate 11 and a downward slider hole 14 that is inclinedly formed in the first slider block 13.

The lower mold core 12 is formed with a first tunnel hole 15 for the first slider rod 19 to be horizontally inserted. The first tunnel hole 15 communicates with the lower mold cavity 26.

[0047] During demolding, the moving mold module 3 moves away from the fixed mold module 1, and the fixed mold plate 11 moves away from the moving mold module 3, so that the lower mold core 12 is exposed outward. The first slider block 13 moves outward at the same time to drive the first slider rod 19 to move away from the lower mold cavity 26 along the first tunnel hole 15, realizing demolding. The first slider rod 19 is inserted into the lower mold cavity 26 through the first tunnel hole 15 of the lower mold core 12, so that the product can form the required hole positions. By setting the tunnel structure, the product and the mold line can be reduced, the processing cost can be reduced, the processing defects can be reduced, and the efficiency can be improved.

Under the action of the inclined guide post 17, the first slider block 13 moves horizontally inward toward the fixed mold core. At the same time, the inner end of the first slider rod 19 of the first slider block 13 is inserted into the lower mold cavity 26 along the first tunnel hole 15. Conversely, during demolding, the moving mold module 3 moves away from the fixed mold module 1. Under the action of the inclined guide post 17, the first slider block 13 moves horizontally outward away from the fixed mold core, driving the first slider rod 19 to move away from the lower mold cavity 26 along the first tunnel hole 15, realizing demolding.

[0049] Preferably, the fixed mold plate 11 is formed with a downward slider chute 2 arranged along the sliding direction of the first slider block 13. The downward slider chute 2 is provided with a slider guide rail 21 along the length direction. Under the action of the slider guide rail 21 of the downward slider chute 2, the first slider block 13 can ensure a linear motion during movement, so that the first slider rod 19 installed on the first slider block 13 and the first tunnel hole 15 always maintain coaxial alignment. The hole positions of the injection-molded products are basically unified, reducing the probability of defective products.

[0050] Preferably, the downward slider chute 2 is further formed with a concave access groove 18.

[0051] Preferably, the moving template 32 is provided with an upward position chute 22 for guiding and sliding the first row position block 13. The moving template 32 is further provided with a limit seat 23. The inner wall of the bottom of the limit seat 23 is formed with a first limit inclined surface 24. The outer end of the first row position block 13 is formed with a second limit inclined surface 25 that slidably cooperates with the first limit inclined surface 24. When the mold is closed, the limit seat 23 installed on the moving template 32 slidably cooperates with the second limit inclined surface 25 at the outer end of the first row position block 13 through the first limit inclined surface 24. Under the action of the inclined surface, the first row position block 13 will move inward along the row position guide rail 21. Under the dual action of the inclined guide post 17 and the limit seat 23, it is ensured that the first row position block 13 after mold closing will not move, further improving the accuracy of the product after injection molding and further reducing the probability of defective products.

[0052] A second row position component 30 is further provided between the moving mold module 3 and the fixed mold module 1. The second row position component 30 includes a row position guide block 34 installed on the moving template 32. The bottom surface of the row position guide block 34 is formed with a top row position inclined surface 35. The moving template 32 is formed with a row position sliding cavity 36. The row position sliding cavity 36 is provided with a second row position block 37 that slidably cooperates with the top row position inclined surface 35. The second row position block 37 is installed with a second row position rod 44 inserted into the lower mold cavity 26. The upper mold core 33 is formed with a second tunnel hole 45 for the second row position rod 44 to be horizontally inserted. The second tunnel hole 45 communicates with the lower mold cavity 26. The moving direction of the second row position block 37 is perpendicular to the moving direction of the first row position block 13. The row position sliding cavity 36 communicates with the fixed template 11. The second row position block 37 is formed with a bottom row position inclined surface 38 that slidably cooperates with the top row position inclined surface 35. When the mold is closed, the top row position inclined surface 35 of the row position guide block 34 slidably cooperates with the bottom row position inclined surface 38 of the second row position block 37. The second row position block 37 moves horizontally along the row position sliding cavity 36 close to the upper mold core 33. At the same time, the inner end of the second row position rod 44 of the second row position block 37 is inserted into the upper mold cavity 45 along the second tunnel hole 45 until the inner end surface of the second row position block 37 abuts against the upper mold core 33, preventing the upper mold core 33 from being horizontally displaced when the mold is closed, ensuring that the upper mold core 33 and the lower mold core 12 are longitudinally coaxially aligned and fitted, and further improving the accuracy of the product after injection molding.

[0053] Preferably, the fixed template 11 is provided with a sliding guide rail 4 for the second row position block 37 to slide. The second row position block 37 can move close to or away from the upper mold core 33 along the sliding guide rail 4. Under the action of the sliding guide rail 4, the second row position block 37 moves in a straight line along the sliding guide rail 4. When the second row position block 37 moves in a straight line, it will not deviate left and right, further improving the stability of the movement and ensuring the accuracy of the product after injection molding.

[0054] Preferably, the slide guide block 34 is formed with an inclined top inclined groove 41, and a connecting slider 42 is installed in the top inclined groove 41; the bottom slide slope 38 of the second slide block 37 is formed with a bottom inclined groove 43 that slides with the connecting slider 42; the top inclined groove 41 and the bottom inclined groove 43 are arranged in parallel and spaced apart, and the cross-sections of the top inclined groove 41 and the bottom inclined groove 43 are both isosceles trapezoids, and the cross-section shape of the connecting slider 42 is an I-shape, and the connecting slider 42 slides with the top inclined groove 41 and the bottom inclined groove 43 respectively.

[0055] When the mold is closed, the top inclined surface 35 of the slide block 34 slides with the bottom inclined surface 38 of the second slide block 37, and the second slide block 37 moves laterally along the slide cavity 36 to approach the upper mold core 33 until the inner end surface of the second slide block 37 abuts against the upper mold core 33; on the contrary, when demolding, the slide block 34 rises, and the top inclined surface 35 of the slide block 34 slides with the bottom inclined surface 38 of the second slide block 37 slides, and the slide block 37 is movably connected to the upper mold core 33 by the connecting slide block 42.

[0056] A guide structure 5 is arranged between the movable mold module 3 and the fixed mold module 1, and the guide structure 5 includes a first connecting seat 51 installed on the outer wall of the fixed mold plate 11, and the first connecting seat 51 is arranged longitudinally; a second connecting seat 54 is installed on the outer wall of the panel 31, and the second connecting seat 54 is formed with a guide groove 55 for the longitudinal sliding of the first connecting seat 51; when the mold is closed and demolded, the first connecting seat 51 will slide longitudinally along the guide groove 55.

[0057] The first connection seat 51 is formed with a first stop seat 52 at the top, the bottom of the first stop seat 52 is a plane, and the top surface is formed with a first outer guide slope 53; the second connection seat 54 is formed with a bottom seat 56 at the bottom, and the inner end of the top of the bottom seat 56 is formed with a second outer guide slope 57.

[0058] Before mold clamping, the stop block 59 is located above the first connecting seat 51; during mold clamping, the moving mold module 3 moves downward. At this time, the bottom surface of the stop block 59 is in sliding fit with the first outer guiding inclined surface 53 of the top surface of the first stop seat 52, and the stop block 59 retracts along the stop groove 58 under the elastic action to allow the first stop seat 52 to pass upward. After mold clamping, the top surface of the stop block 59 is in stop fit with the bottom surface of the first stop seat 52, which can prevent the fixed mold module 1 from disengaging downward from the moving mold module 3 and ensure the stability after mold clamping.

[0059] After mold clamping, the bottom seat 56 at the bottom of the second connecting seat 54 is located below the stop block 59. During demolding, the panel 31 moves upward to drive the second connecting seat 54 to move upward. At this time, the second outer guiding inclined surface 57 of the top surface of the bottom seat 56 is in sliding fit with the bottom surface of the stop block 59, and the stop block 59 retracts along the stop groove 58 under the elastic action to allow the bottom seat 56 to pass upward, realizing demolding.
