The fixing manner of the rear mold insert 12 on the rear mold core 20 is the same as the fixing manner of the front mold insert 11 on the front mold core 10, but the vertical direction is changed, and the description thereof is omitted.
The ejector pin plate 1 is arranged on the inner side of the square iron block 8, one end of the ejector pin 2 is fixed on the ejector pin plate 1, the other end of the ejector pin can penetrate through the rear template 7 and the rear die insert 12 and then extend into the cavity 30, and when the ejector pin 2 moves upwards, a product after injection molding in the cavity 30 can be ejected.
The number of the front mold insert 3 and the number of the rear mold insert 4 are all multiple, the rear mold insert 12 is provided with a plurality of mounting holes 121, one end of the rear mold insert 4 is fixed in each mounting hole 121 and is arranged in a one-to-one correspondence with each mounting hole 121, namely, one rear mold insert 4 is fixed in each mounting hole 121. The number of the front mold insert pins 3 and the rear mold insert pins 4 is consistent with the number of jacks in the direction which are required to be molded in the plug shell, and the injection molding requirement is met. In the mold closing process, the bottom end of the front mold insert 3 is matched with the top end of the rear mold insert 4 and both are positioned in the cavity 30, specifically, an opening 301 is formed at the bottom end of the front mold insert 3, a tapered portion 43 is formed on the top end surface of the rear mold insert 4, and the tapered portion 43 is inserted into the opening 301. The tapered portion 43 has a smaller outer diameter at its top end than its bottom end, facilitating better guided insertion into the opening 301 and improved tightness of mating therewith, thereby facilitating formation of corresponding receptacles in a corresponding plug housing (as shown in fig. 12).
The rear mold insert 4 includes a square portion 41 and a cylindrical portion 42, the cylindrical portion 42 is located above the square portion 41, the mounting hole 121 is a square hole, the square portion 41 is located in the mounting hole 121 and is matched with the mounting hole 121, the cylindrical portion 42 is located above the mounting hole 121, and the outer diameter of the cylindrical portion 42 is larger than the length and width of the square portion 41. Wherein, the rear mould insert needle 4 is of an integrated structure.
Because the dimensions of the square portion 41 in the length direction and the width direction are smaller than the outer diameter of the cylindrical portion 42, the length and the width dimensions of the mounting holes 121 are reduced, so that the wall thickness between the adjacent mounting holes 121 can be increased, the strength of the rear mold insert is improved, the side wall of the mounting hole is prevented from being damaged during mold locking injection, the service life of the rear mold insert 12 is greatly prolonged, the service life of the whole mold is prolonged, and the injection cost of products is reduced.
The mounting hole 121 has a boss 13 formed on an upper end surface thereof, the boss 13 being located on an upper end surface of the rear mold insert 12, and a bottom end of the cylindrical portion 42 being in contact with the upper end surface of the boss 13. Therefore, in injection molding, the matching of the bulge 13 and the cylindrical part 42 can facilitate the injection molding of corresponding chamfer angles of the product jack, and meanwhile, the cylindrical part 42 is prevented from being tightly adhered to the rear mold insert 12, so that the demolding is facilitated.
The upper end surface of the bulge 13 is provided with a plurality of sinking grooves 131, the plurality of sinking grooves 131 are arranged at intervals, and two ends of the sinking grooves 131 are respectively communicated with the cavity 30 and the mounting hole 121. The four sinking grooves 131 on each protrusion 13 are respectively positioned at the four top corners of the mounting hole 121, so that the gas in the cavity can be better discharged from the sinking grooves 131 to the top corners of the mounting hole 121 during injection molding.
In the actual production process, the depth of the sinking groove 131 is 0.012mm, so that the gas in the cavity 30 can be extruded and discharged by the injection molding colloid, and the injection molding colloid is ensured not to flow out of the sinking groove 131 during injection molding.
A limiting rod 14 is arranged in the rear mold insert 12, limiting grooves 411 are formed in the side walls of the square parts 41 of the rear mold insert pins 4, and the limiting rod 14 is matched with the limiting grooves 411. The limiting rod 14 is inserted from the side face of the rear die insert 12, two ends of the limiting rod 14 are transversely arranged in the rear die insert 12 and fixed with two sides of the rear die insert needle 4, and when the limiting rod 14 is inserted, the limiting rod 14 is matched with the limiting slot 411, and the side face of the limiting rod is clamped into the limiting slot 411, so that the fixing of the position of the rear die insert needle 4 is realized.
The front mold insert 3 is fixed in the front mold insert 11 in the same manner as the rear mold insert 4 is fixed in the rear mold insert 12.
As shown in fig. 3 to 9, the injection mold for a plug housing of the present invention further includes a side insert 15, a first slider 16, a first inclined guide 17, a first moving block 18 and a first guide block 19, wherein the first inclined guide 17 is inclined, one end of the first inclined guide 17 is fixed on the front mold plate 6, the other end of the first inclined guide 17 can penetrate through the first moving block 18, the side insert 15 is horizontally arranged, one end of the side insert is fixed on the first slider 16, the other end of the side insert extends into the cavity 30, the first slider 16 is arranged on the rear mold plate 7 and is located at one side of the cavity 30, the first slider 16 is fixedly connected with the first moving block 18, the top end of the first guide block 19 is fixed on the front mold plate 6, one side of the first guide block 19 is provided with a first inclined surface 191, the direction of the first inclined surface 191 is consistent with the inclined direction of the first inclined guide 17, the outer side of the first moving block 18 is provided with a second inclined surface 181, the first inclined surface 191 can be attached to the second inclined surface 181, and the first moving block 18 is located on the rear mold plate 7.
The side insert pins 15 are arranged, so that the insertion holes on the corresponding side surfaces of the plug shell can be injection molded, and the number of the side insert pins 15 is correspondingly increased or reduced according to the number of the insertion holes on the corresponding side, so that different use requirements are met. Each side insert pin 15 is inserted between two adjacent rear mould insert pins 4, and the side insert pins 15 are tightly attached to the rear mould insert pins 4, so that jacks in two directions can be communicated after injection molding of a product is completed, and subsequent assembly and use of the plug shell are facilitated.
The side insert pin 15 is fixed to the first slider 16 in the same manner as the rear insert pin 4 is fixed to the rear mold insert. Therefore, the side insert pin 15 can be driven to move synchronously by the first slider 16. Specifically, when the mold is closed, the first inclined surface 191 of the first guide block 19 gradually contacts with the second inclined surface 181 of the first moving block 18, and as the first guide block 19 is gradually pushed down by the driving of the front mold plate 6, the first guide block 19 pushes the first moving block 18 to gradually move to a side close to the cavity 30, and simultaneously, the first inclined guide rod 17 also acts on the first moving block 18 to push the first moving block 18 and limit the first moving block 18 when moving in place. The first moving block 18 drives the first sliding block 16 to synchronously move, and the first sliding block 16 drives the side insert 15 to extend into the cavity 30 and finally extend into place.
Therefore, by matching the second inclined surface 181 with the first inclined surface 191, when the mold is closed, the first slide block 16 is driven to move only by the front mold plate 6 closing downward without pushing the first slide block 16 to be close to the cavity 30 by additional power, and the structure of the mold is simplified. Meanwhile, since the first sliding block 16 is located on the side face of the cavity 30, the side, close to the cavity 30, of the first sliding block 16 can mold the corresponding side face shape of a product, when demolding, the first sliding block 16 slides away from the side face to the side, away from the cavity, of the first sliding block, demolding can be achieved, and demolding is not needed according to the number of the step faces of the side face, the structure of the mold is greatly slowed down, and demolding is more convenient and rapid.
Similarly, when the die is required to be demolded, the front die plate 6 moves upwards to drive the first inclined guide rod 17 to move upwards together, when the first inclined guide rod 17 moves upwards, the front die plate 6 acts on the first moving block 18 to drive the first moving block 18 to move outwards, meanwhile, the front die plate 6 drives the first guide block 19 to move upwards, so that the first inclined surface 191 also gradually moves upwards, and after the first guide block 19 moves upwards, due to the arrangement of the first inclined surface 191, enough space is provided for the first moving block 18 to move outwards until the side insert 15 is pulled out from the die cavity 30, and separation from products is realized.
The plug housing injection mold further comprises a second sliding block 21, a first mosaic block 22, a second inclined guide rod 23, a second moving block 24 and a second guide block 25, wherein the second sliding block 21 is positioned at the other side of the cavity 30 and is opposite to the first sliding block 16, one end of the second inclined guide rod 23 is fixed on the front template 6, the other end of the second inclined guide rod can penetrate through the second moving block 24, the second moving block 24 is positioned on the rear template 7, the second sliding block 21 is fixedly connected with the second moving block 24, the first mosaic block 22 is fixed on the second sliding block 21 and is matched with the cavity 30, the top end of the second guide block 25 is fixed on the front template 6, a third inclined surface 251 is arranged on the inner side of the second guide block 25, a fourth inclined surface 241 is arranged on the outer side of the second moving block 24, and the third inclined surface 251 can be attached to the fourth inclined surface 241.
In actual use, during die assembly, the second slider 21 and the first mosaic block 22 are matched with the die cavity 30, so that the corresponding side wall of a product is formed conveniently, the first mosaic block 22 is fastened above the second slider 21 through screw locks, and the consistency of movement of the first mosaic block 22 and the second slider 21, namely the consistency of die opening and die assembly of the first mosaic block 22 and the second slider 21, is maintained.
When the die is closed, the second guide block 25 moves downwards along with the front die plate 6, the third inclined surface 251 on the second guide block 25 acts on the fourth inclined surface 241 of the second moving block 24, the second moving block 24 is pushed to move to the side of the die cavity 30 by the second guide block 25, and the second moving block 24 drives the second slide block 21 and the first mosaic block 22 to synchronously move to the side of the die cavity, so that the second slide block 21 and the first mosaic block 22 are matched with the die cavity 30 to realize the die closing.
