Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold with a multi-angle inclined slider. Background Technology

[0002] Injection molding is a method of industrial product manufacturing, typically using rubber or plastic injection molding. It can be further divided into injection molding compression molding and die casting. An injection mold is a tool used for mass production of plastic products. By injecting molten plastic into the mold cavity and allowing it to cool and solidify, a plastic product with precise dimensions and complex structures is formed. Before ejection, the assembly clips need to be demolded. Because the demolding position of these assembly clips is small, a slanted ejector structure is generally used. Traditional slanted ejector structures are simple, but the free adjustment of the angle during ejection can lead to errors such as jamming or breakage, and replacement is also relatively difficult. To make product ejection smoother, a multi-angle slanted slide injection mold is proposed.

[0003] As disclosed in the authorization announcement number CN213006345U, a multi-angle adjustable inclined ejector structure based on an injection mold includes a connecting mechanism; the connecting mechanism has a threaded hole for easy connection with the mold, and a sliding seat is slidably connected; an adjusting mechanism is rotatably connected to the sliding seat, and a circular connecting rod for easy installation and swinging is machined on the adjusting mechanism; an inclined ejector is snapped into the adjusting mechanism, and a T-shaped groove for easy installation of the inclined ejector is provided on the adjusting mechanism;

[0004] Although this utility model improves the connection structure of the base, it provides a rectangular nut placement seat on the base, and a connecting nut is provided on the nut placement seat through a hexagonal groove. The nut placement seat is connected to the base through a rectangular connecting protrusion. The connecting nut in the nut placement seat can be replaced individually, saving costs. The rectangular nut placement seat increases the circumferential force generated when the bolt is fixed.

[0005] However, this does not solve the problem that existing injection molds are not conducive to the automatic connection and disconnection of inclined sliders during use, which hinders the rapid demolding and output of materials and affects the convenience of material demolding. Utility Model Content

[0006] The purpose of this invention is to provide an injection mold with a multi-angle inclined slider, so as to solve the problem mentioned in the background art that the injection mold is not convenient for automatic connection and disconnection of the inclined slider, which is not conducive to the rapid demolding output of materials and affects the convenience of material demolding.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle inclined slider injection mold, including a right mold base and a fixed base. The fixed base is provided on the side wall of the right mold base. Connecting columns are symmetrically arranged on the side wall of the fixed base, and tension springs are provided on the side walls of the connecting columns. Limit seats are provided on the side wall of the fixed base on one side of the tension springs. A moving block is provided between the two sets of limit seats, and the moving block is slidably connected to the limit seats. The tension spring is connected to the moving block. A wedge groove is provided inside the moving block, and a wedge block is provided inside the wedge groove. The wedge block is slidably connected to the wedge groove. A left mold base is provided outside the right mold base, and the wedge block is connected to the left mold base. A T-shaped block is provided on the side wall of the moving block, and a release block is provided on the surface of the T-shaped block. A T-shaped groove is provided on the side of the release block near the T-shaped block, and the T-shaped groove is slidably connected to the T-shaped block.

[0008] Preferably, the right mold base is symmetrically provided with electric push rods inside, and each of the electric push rods has a push arm installed at its output end.

[0009] Preferably, the end of the push arm away from the electric push rod is provided with a rack, and the rack is slidably connected to the right mold base, and the right mold base on one side of the rack is provided with three sets of L-shaped frames at equal intervals.

[0010] Preferably, a lead screw is movably mounted on the surface of the L-shaped frame, and a threaded sleeve is provided on the surface of the lead screw, and the threaded sleeve is threadedly connected to the lead screw.

[0011] Preferably, the lead screw surface on one side of the rack is provided with gears, and the gears mesh with the rack.

[0012] Preferably, each of the threaded sleeves is provided with a lifting sleeve on its surface, and each of the lifting sleeves is provided with a limit block on its side wall, and the lifting sleeve is slidably connected to the L-shaped frame through the limit block.

[0013] Preferably, the top of both the left and right mold bases are provided with multiple sets of lifting rings, and the left mold base is provided with a bolt bracket on its exterior.

[0014] Preferably, the bolt holder can be inserted into the inside of the lifting ring, and the surface of the bolt holder is provided with nuts, and the nuts are threadedly connected to the bolt holder.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the injection mold not only realizes the automatic connection and disconnection of the inclined slider, which facilitates the rapid demolding output of materials, but also improves the convenience of material demolding;

[0016] (1) The left mold base of the injection mold is installed on the power end of the injection molding machine, and the right mold base is installed on the fixed end of the injection molding machine. After injection molding is completed, the power end of the injection molding machine drives the left mold base to move, and the left mold base drives the wedge block to move in the wedge groove. Both the wedge block and the wedge groove are wedge-shaped. When the wedge block moves out of the wedge groove, under the tension of the tension spring, the tension spring drives the moving block to slide in the limit seat. The moving block drives the release block to move through the T-block, so that the release block is released from the surface of the workpiece. When the left and right mold bases are closed, the wedge block is reinserted into the wedge groove. Under the sliding engagement of the wedge block and the wedge groove, the wedge block drives the moving block to move and reset, so that the wedge block abuts against the injection point again, thus completing the use of the inclined slider. When it is necessary to remove the release block, simply slide the release block. Under the sliding engagement of the T-slot and the T-block, the release block can be removed from the surface of the T-block. The above design can realize the automatic connection and release of the inclined slider, which can facilitate the rapid demolding of materials.

[0017] (2) After the left mold base and the right mold base are separated, the electric push rod is turned on. The electric push rod drives the push arm to move, and the push arm drives the rack to move. Under the mutual meshing of the rack and gear, the rack drives the gear to rotate. Under the movable cooperation of the lead screw and the L-shaped frame, the gear drives the lead screw to rotate. Under the threaded connection between the lead screw and the threaded sleeve, the lead screw drives the threaded sleeve to move. Under the sliding cooperation of the limit block, the threaded sleeve drives the lifting sleeve to move. Multiple sets of lifting sleeves move synchronously. The lifting sleeve pushes the material out of the right mold base, realizing the material separation process. After the mold is used up, multiple sets of lifting rings are installed sequentially on the left and right mold bases. The left and right mold bases are then closed. Bolt brackets are then inserted into the lifting rings, and nuts are fitted onto the surface of the bolt brackets and tightened. This secures the corresponding lifting rings through the bolt brackets, thus fixing the left and right mold bases together and preventing them from separating or falling off during transport. This design allows for the ejection of the processed product and connects and fixes the two mold bases to prevent them from separating or falling off during transport. Attached Figure Description

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figure 1-5 This utility model provides an embodiment of an injection mold with a multi-angle inclined slider, including a right mold base 2 and a fixed base 6. The fixed base 6 is provided on the side wall of the right mold base 2. Connecting posts 15 are symmetrically arranged on the side wall of the fixed base 6, and tension springs 16 are provided on the side walls of each connecting post 15. Limiting seats 18 are provided on the side wall of the fixed base 6 on one side of each tension spring 16. A moving block 17 is provided between the two sets of limiting seats 18, and the moving block 17 is slidably connected to the limiting seat 18. The tension spring 16 is connected to the moving block 17. The movable block 17 is connected to the moving block 17. The inside of the movable block 17 is provided with a wedge groove 23, and the inside of the wedge groove 23 is provided with a wedge block 22. The wedge block 22 is slidably connected to the wedge groove 23. The outside of the right mold base 2 is provided with a left mold base 1, and the wedge block 22 is connected to the left mold base 1. The side wall of the movable block 17 is provided with a T-shaped block 19, and the surface of the T-shaped block 19 is provided with a release block 21. The side of the release block 21 near the T-shaped block 19 is provided with a T-shaped groove 20, and the T-shaped groove 20 is slidably connected to the T-shaped block 19.

[0026] The left mold base 1 of the injection mold is installed on the power end of the injection molding machine, and the right mold base 2 is installed on the fixed end of the injection molding machine. After injection molding is completed, the power end of the injection molding machine drives the left mold base 1 to move, and the left mold base 1 drives the wedge block 22 to move in the wedge groove 23. Both the wedge block 22 and the wedge groove 23 are wedge-shaped. When the wedge block 22 moves out of the wedge groove 23, under the tension of the tension spring 16, the tension spring 16 drives the moving block 17 to slide in the limiting seat 18. The moving block 17 drives the release block 21 to move through the T-block 19, so that the release block 21 disengages from the surface of the workpiece. When the left mold base 1 and the right mold base 2 are closed, the wedge block 22 is reinserted into the wedge groove 23. Under the sliding engagement of the wedge block 22 and the wedge groove 23, the wedge block 22 drives the moving block 17 to move and reset, so that the wedge block 22 abuts against the injection point again, thus completing the use of the inclined slider. When it is necessary to remove the release block 21, simply slide the release block 21. Under the sliding engagement of the T-slot 20 and the T-block 19, the release block 21 can be removed from the surface of the T-block 19. The above design can realize the automatic connection and disconnection of the inclined slider, which can facilitate the rapid demolding of materials.

[0027] Electric push rods 7 are symmetrically arranged inside the right mold base 2, and push arms 9 are installed at the output ends of the electric push rods 7.

[0028] The push arm 9 is equipped with a rack 10 at the end away from the electric push rod 7, and the rack 10 is slidably connected to the right mold base 2. Furthermore, three sets of L-shaped frames 8 with equal spacing are provided inside the right mold base 2 on one side of the rack 10.

[0029] All surfaces of the L-shaped frame 8 are movably mounted with lead screws 24, and all surfaces of the lead screws 24 are provided with threaded sleeves 12, and the threaded sleeves 12 are threadedly connected to the lead screws 24. All surfaces of the lead screws 24 on one side of the rack 10 are provided with gears 11, and the gears 11 mesh with the rack 10.

[0030] The surface of the threaded sleeve 12 is provided with a lifting sleeve 13, and the side wall of the lifting sleeve 13 is provided with a limit block 14. The lifting sleeve 13 is slidably connected to the L-shaped frame 8 through the limit block 14.

[0031] Multiple sets of lifting rings 3 are provided at the top of both the left mold base 1 and the right mold base 2, and a bolt bracket 4 is provided on the outside of the left mold base 1;

[0032] The bolt bracket 4 can be inserted into the inside of the lifting ring 3, and the surface of the bolt bracket 4 is provided with nuts 5, and the nuts 5 are threadedly connected to the bolt bracket 4;

[0033] After the left mold base 1 and the right mold base 2 are separated, the electric push rod 7 is activated, which drives the push arm 9 to move. The push arm 9 then drives the rack 10 to move. With the rack 10 meshing with the gear 11, the rack 10 drives the gear 11 to rotate. With the movable engagement of the lead screw 24 and the L-shaped frame 8, the gear 11 drives the lead screw 24 to rotate. With the threaded connection between the lead screw 24 and the threaded sleeve 12, the lead screw 24 drives the threaded sleeve 12 to move. With the sliding engagement of the limit block 14, the threaded sleeve 12 drives the lifting sleeve 13 to move. Multiple lifting sleeves 13 move synchronously, and the lifting sleeves 13 push the material out of the right mold base 2. This design enables the separation of materials. After the mold is used, multiple sets of lifting rings 3 are installed sequentially on the left mold base 1 and the right mold base 2, closing the left mold base 1 and the right mold base 2. Then, the bolt bracket 4 is inserted into the lifting rings 3, and the nuts 5 are fitted onto the surface of the bolt bracket 4 and tightened, so that the corresponding lifting rings 3 are fixedly connected through the bolt bracket 4. This fixes the left mold base 1 and the right mold base 2, preventing them from separating or falling off during transportation. The above design can eject the processed products and connect and fix the two mold bases to prevent them from separating or falling off during transportation.

[0034] Working principle: The left mold base 1 of this injection mold is installed on the power end of the injection molding machine, and the right mold base 2 is installed on the fixed end of the injection molding machine. After injection molding is completed, the power end of the injection molding machine drives the left mold base 1 to move, and the left mold base 1 drives the wedge block 22 to move in the wedge groove 23. Both the wedge block 22 and the wedge groove 23 are wedge-shaped. When the wedge block 22 moves out of the wedge groove 23, under the tension of the tension spring 16, the tension spring 16 drives the moving block 17 to slide in the limit seat 18. The moving block 17 drives the release block 21 to move through the T-block 19, thereby releasing the release block 21. When block 21 detaches from the surface of the workpiece, and the left mold base 1 and right mold base 2 close, wedge block 22 re-inserts into the wedge groove 23. Under the sliding engagement of wedge block 22 and wedge groove 23, wedge block 22 drives moving block 17 to move and reset, causing wedge block 22 to re-abut against the injection point, thus completing the operation of the inclined slider. When it is necessary to remove the release block 21, simply slide the release block 21. Under the sliding engagement of T-slot 20 and T-block 19, the release block 21 can be removed from the surface of T-block 19. After the left mold base 1 and right mold base 2 separate... At this time, the electric push rod 7 is activated, which drives the push arm 9 to move. The push arm 9 then drives the rack 10 to move. Under the meshing of the rack 10 and the gear 11, the rack 10 drives the gear 11 to rotate. Under the movable cooperation of the lead screw 24 and the L-shaped frame 8, the gear 11 drives the lead screw 24 to rotate. Under the threaded connection between the lead screw 24 and the threaded sleeve 12, the lead screw 24 drives the threaded sleeve 12 to move. Under the sliding cooperation of the limit block 14, the threaded sleeve 12 drives the lifting sleeve 13 to move. Multiple sets of lifting sleeves 13 move synchronously, and the lifting sleeves 13 push the material from the right... The material is ejected from the mold base 2 to achieve the separation process. After the mold is used up, multiple sets of lifting rings 3 are installed on the left mold base 1 and the right mold base 2 in sequence, and the left mold base 1 and the right mold base 2 are closed. Then, the bolt bracket 4 is inserted into the lifting ring 3, the nut 5 is put on the surface of the bolt bracket 4 and tightened, so that the corresponding lifting ring 3 is fixedly connected through the bolt bracket 4, thereby fixing the left mold base 1 and the right mold base 2 and preventing the left mold base 1 or the right mold base 2 from separating and falling off during the transfer process. The above is the complete usage of the injection mold with multi-angle inclined slider.
