Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The mold provided by the embodiment of the invention is used for injection molding of injection molding parts, and is particularly used for injection molding of injection molding parts with structures such as an inverted buckle, a buckling position, a hole, a recess or a boss; of course, in other embodiments of the present invention, the mold can also be used for injection molding of other injection molded parts, or other processing procedures of other injection molded parts, and is not limited herein.

Referring to fig. 1, fig. 2, fig. 4 to fig. 6 and fig. 10, a mold according to an embodiment of the present invention will now be described. The mold includes a first body 10 and a second body 20. The first mold body 10 and the second mold body 20 are enclosed to form an injection molding space. The first and

second bodies

10, 20 are relatively movable in a first direction to effect opening and closing of the mold. I.e., the first and

second bodies

10, 20 are moved toward one another in a first direction to effect mold clamping. The first mold body 10 and the second mold body 20 are moved away from each other in a first direction to open the mold. Further, the first mold body 10 includes a first body 11, a slider 12, an inclined ejecting block 13 and a driving mechanism 14, the slider 12 and the inclined ejecting block 13 are accommodated in the injection molding space, the slider 12 is disposed on the inclined ejecting block 13, the second mold body 20 can move along the first direction to drive the slider 12 to slide from the initial position to the first position along the second direction relative to the first body 11, when the slider 12 is located at the first position, the driving mechanism 14 can drive the inclined ejecting block 13 to slide along the third direction relative to the first body 11 along the first direction, and the third direction is obliquely arranged relative to the first direction. In this embodiment, the first direction is parallel to the direction indicated by the arrow X in fig. 1, the second direction is parallel to the direction indicated by the arrow Y in fig. 1, and the third direction is parallel to the direction indicated by the arrow Z in fig. 1.

In summary, the embodiment of the invention has the following beneficial effects: the mold of the above scheme can avoid the adoption of the inclined ejecting seat to drive the inclined ejecting block 13 besides having excellent injection molding efficiency. Specifically, the mold includes a first mold body 10 and a second mold body 20 enclosing a molding space. The first mold body 10 and the second mold body 20 can relatively move along a first direction to realize opening and closing of the mold, wherein the first mold body 10 comprises a first body 11, a driving mechanism 14, a sliding block 12 and an inclined ejecting block 13 which are accommodated in an injection molding space, and thus the shape of the injection molding part 40 can be limited through the second mold body 20, the first body 11, the sliding block 12 and the inclined ejecting block 13. Further, the second mold body 20 can be moved along the first direction to drive the slider 12 to slide along the second direction relative to the first body 11 from the initial position to the first position, and when the slider 12 is located at the first position, the driving mechanism 14 can drive the slanted ejecting block 13 to slide along the first direction relative to the first body 11, and the third direction is obliquely arranged relative to the first direction. Therefore, the output end of the driving mechanism 14 can move in the same direction as the mold opening direction to drive the inclined ejecting block 13 to move obliquely, and a driving mode in the same direction as the movement direction of the inclined ejecting block 13 is avoided, so that the mold space occupied by the output end of the avoiding driving mechanism 14 is reduced.

In one embodiment, as shown in fig. 1, 5, 10, and 12, drive mechanism 14 includes a drive block 141 and a drive assembly 142. The driving block 141 is provided with a first sliding portion 1411 extending in the second direction. The inclined ejector block 13 is provided with a second sliding part extending along the second direction and a third sliding part extending along the third direction. The first body 11 is provided with a fourth sliding portion 110 extending in the third direction. The driving assembly 142 can drive the driving block 141 to move along the first direction, so that the first sliding portion 1411 and the second sliding portion slide relatively along the second direction, and the third sliding portion and the fourth sliding portion 110 slide relatively along the third direction. Through the mutual matching between the first sliding portion 1411 and the second sliding portion, and between the third sliding portion and the fourth sliding portion 110, the movement of the driving block 141 along the first direction can be converted into the oblique movement of the slanted ejecting block 13 along the third direction, and meanwhile, the stability of the transmission among the driving block 141, the slanted ejecting block 13 and the first body 11 is ensured. Specifically, the driving block 141 moves in the first direction to apply an upward force to the lifter block 13, and the lifter block 13 has a tendency to move in the third direction due to the restriction of the third and fourth sliding portions 110, while the engagement between the first and second sliding

portions

1411 and 1411 does not hinder the movement of the lifter block 13 in the third direction. In summary, driving the lifter block 13 in the first direction by the driving block 141 can move the lifter block 13 in the third direction.

In one embodiment, one of the first and second sliding

portions

1411 and 1411 is a groove and the other is a protrusion. One of the third sliding portion and the fourth sliding portion 110 is a groove, and the other is a protrusion. The transmission stability between the driving block 141, the inclined ejecting block 13 and the first body 11 can be further improved by the matching of the groove and the protrusion. As shown in fig. 5, 6, 8, 10, and 12, in the present embodiment, the first sliding portion 1411 and the third sliding portion are grooves, and the second sliding portion and the fourth sliding portion 110 are protrusions. Further, in the present embodiment, the first body 11 includes a rail block 111. The fourth sliding portion 110 is formed on the rail block 111.

Further, with reference to fig. 5, 6, 8, 10 and 12, the number of the first sliding portions 1411 is two and the first sliding portions are disposed along a plane perpendicular to the first direction and the second direction. The number of the second sliding portions is two and the second sliding portions are matched with the first sliding portions 1411 in a one-to-one correspondence manner. Specifically, two first sliding portions 1411 are respectively located at both sides of the driving block 141. The slanted ejecting block 13 is provided with a slot, and the second sliding portion is formed on two opposite slot walls of the slot, so that at least part of the driving block 141 is accommodated in the slot and abuts against the slot bottom of the slot, thereby further improving the stability of transmission between the driving block 141 and the slanted ejecting block 13. Further, the first sliding portions 1411 are grooves, and the two first sliding portions 1411 are distributed in an i-shaped manner on the driving block 141, so that the driving block 141 and the lifter block 13 are further prevented from moving in the first direction. The number of the third sliding portions is two and is arranged along a plane perpendicular to the first direction and the second direction, and the number of the fourth sliding portions 110 is two and is matched with each third sliding portion in a one-to-one correspondence manner. Specifically, two third sliding portions are respectively located on both sides of the lifter block 13. The number of the guide rail blocks 111 is two, and the guide rail blocks are positioned on two sides of the inclined top block 13. The two fourth sliding portions 110 are formed on the two rail blocks 111, respectively. This enables the two rail blocks 111 to sandwich the lifter block 13, ensuring stability of sliding between the third sliding portion and the fourth sliding portion 110. Further, the third sliding portion is a groove, and the fourth sliding portion 110 is a protrusion. It is understood that in other embodiments, the first sliding portion 1411, the second sliding portion, the third sliding portion, and the fourth sliding portion 110 may also be distributed in a plurality along the distribution of the first direction to form a sliding group. The number of the sliding groups is two and the sliding groups are arranged along a plane perpendicular to the first direction and the second direction, so that the stability of transmission between the inclined ejecting block 13 of the driving block 141 and the first body 11 is further improved.

In one embodiment, as shown in fig. 5, 7, 10 and 12, the driving assembly 142 includes a top bar 1421, a guide sleeve 1422 and an adjusting member 1423, and the first body 11 is provided with a guide groove 112 and a through hole communicating with the guide groove 112. The driving block 141 is accommodated in the guide groove 112. The guide groove 112 can limit the moving direction of the driving block 141, and ensure that the driving block can stably move along the first direction. Further, the top bar 1421 penetrates through the through hole and is connected with the driving block 141, the guide sleeve 1422 is accommodated in the through hole, and the guide sleeve 1422 is annularly arranged on the top bar 1421 and is slidably connected with the top bar 1421. The arrangement of the guide sleeve 1422 can reduce the abrasion loss between the top bar 1421 and the first body 11 when driving the driving block 141, and meanwhile, the arrangement of the guide sleeve 1422 can further ensure the accuracy of the movement of the top bar 1421 along the first direction. In this embodiment, the guide sleeve 1422 is detachably connected to the first body 11, so that the guide sleeve 1422 can be conveniently replaced when the precision is reduced after being worn. Further, the adjusting part 1423 is coaxial with the top bar 1421, and the adjusting part 1423 can adjust the protruding amount of the top bar 1421 relative to the top bar 1421 along the axial direction of the top bar 1421. This allows for different ends to be driven by adjusting the amount of extension of the adjustment member 1423. In this embodiment, the adjusting member 1423 is connected to the ejector plate 30. The ejector bar of the injection molding machine drives the ejector 1421 through the ejector plate 30, and further drives the driving block 141 to move in the first direction.

In one embodiment, as shown in fig. 2, 6, 10 and 13, the slider 12 is provided with a first inclined guide 121. The second casing 20 is provided with a second inclined guide portion 21. The second mold 20 moves in the first direction to move the first inclined guiding portion 121 relative to the second inclined guiding portion 21, so as to drive the slider 12 to slide in the second direction relative to the first body 11 from the initial position to the second position, where the second position is located on a side of the first position away from the initial position. This is so that the first and second

angled guides

121 and 21 remain engaged when the slider 12 is in the first position. In this embodiment, the first inclined guiding portion 121 is an inclined hole, and the second inclined guiding portion 21 is an inclined guide post, so that the second mold block 20 moves along the first direction to drive the slide block 12 to move along the second direction.

In one embodiment, as shown in fig. 5, 6, 10 and 11, the first mold body 10 further includes a reset assembly 15, and the reset assembly 15 is used for resetting the slide 12 after the first inclined guide portion 121 is separated from the second inclined guide portion 21. Therefore, when the mold is closed again, the slide block 12 can be at the preset position, and the interference caused by the mold closing is avoided.

Further, as shown in fig. 11, the reset assembly 15 includes a guide block 151, a guide rod 152, and a first elastic member 153. The guide block 151 is provided to the lifter block 13. The guide rod 152 is slidably coupled to the guide block 151. One end of the guide rod 152 is connected to the slider 12, and the other end thereof penetrates through the guide block 151 and is provided with a first stopper portion 1521. The first elastic member 153 is located between the first stopping portion 1521 and the guide block 151 to be able to generate a driving force in the second direction when the first inclined guide portion 121 and the second inclined guide portion 21 relatively move. The stability of the direction in which the first elastic member 153 generates the driving force can thus be ensured by the restriction of the guide rod 152 and the guide block 151. Meanwhile, the guide block 151 is provided to serve as a stopper to prevent the stopper 12 from exceeding the movable range. In this embodiment, the guide block 151 and the inclined top block 13 are detachably connected by a bolt, and can be replaced when the guide block 151 is damaged. In another example, the inclined top block 13 is provided with a plurality of positions for installing the guide blocks 151, so that the inclined top block can be conveniently installed at different positions through the guide blocks 151 to limit the movable range of the sliding block 12. It is understood that in other embodiments, the guide block 151 may be integrally formed with the lifter block 13, so as to facilitate the integral manufacture.

In one embodiment, as shown in fig. 6, the guide rod 152 is threadedly coupled to the slider 12 to enable adjustment of its extension relative to the slider 12. By adjusting the extension of the guide rod 152 in this way, the magnitude of the driving force generated by the first elastic member 153 can be adjusted to increase the speed of the slider 12 being reset.

In one embodiment, as shown in fig. 11 and 13, two ends of the sliding block 12 are respectively provided with a pressing block 16, and the pressing blocks 16 are connected with the sliding block 12 and are used for attaching the sliding block 12 to the inclined ejecting block 13. The setting through briquetting 16 like this guarantees slider 12 and the laminating of oblique kicking block 13, and then guarantees the stability that slider 12 removed to the oblique kicking block 13 relatively. Furthermore, the two ends of the slider 12 are respectively provided with a sliding slot 120, the sliding slot 120 penetrates through the slider 12 along the second direction, and at least part of the pressing block 16 is accommodated in the sliding slot 120 so as to be slidably connected with the slider 12 and attach the slider 12 to the inclined top block 13.

In one embodiment, as shown in fig. 9, 11 and 13, the first mold body 10 further includes an insert assembly 17. The insert assembly 17 is inserted into the slider 12 and slidably connected with the slider 12, and at least a part of the insert assembly protrudes out of the slider 12. The slide 12 also includes a third position on the sliding path with respect to the first body 11. The third position is between the initial position and the first position, and the movement of the second mold body 20 in the first direction drives the slide 12 to slide in the second direction relative to the first body 11 from the initial position to the third position and restricts the movement of the insert assembly 17 in the second direction. Insert assembly 17 is used to form a hole, pocket or boss in injection molded part 40. The shape of the injection molded part 40 can thus be defined by the second mold body 20, the first body 11, the slide block 12, the lifter block 13, and the insert assembly 17. Therefore, when the injection molding of the injection molding part 40 is finished, the second mold body 20 moves along the first direction to open the mold, the slide block 12 is separated from the injection molding part 40, the insert component 17 does not move and is still in contact with the position where the hole, the concave cavity or the boss is formed on the injection molding part 40, and the damage to the hole, the concave cavity or the boss formed on the injection molding part 40, caused by the movement of the insert component 17 along with the slide block 12, is avoided.

In one embodiment, as shown in FIGS. 3, 9 and 14, the second mold body 20 is provided with a first surface 22, the first surface 22 extending in a first direction and perpendicular to a second direction. Insert assembly 17 is provided with a second surface 171. The second surface 171 is capable of engaging and sliding relative to the first surface 22 when the slider 12 slides from the initial position to the third position. The movement of the insert assembly 17 is thus limited by the cooperation of the first surface 22 and the second surface 171 so as not to move relative to the injection molded part 40 when the slide 12 is separated from the injection molded part 40, separation of the slide 12 from the injection molded part 40 being achieved by relative sliding of the slide 12 and the insert assembly 17. In this embodiment, since the first surface 22 and the second surface 171 are parallel to the first direction, when the first surface 22 moves along the second mold body 20 along the first direction, the first surface 22 can slide relative to the second surface 171 without driving the insert assembly 17, and at the same time, the movement of the insert assembly 17 along the second direction can be limited, thereby ensuring the stability of the connection between the insert assembly 17 and the injection molded part 40. It is understood that in other embodiments, the second mold body 20 may also be provided with positioning members to fix the position of the insert assembly 17, such as a rod-like structure, such as a pin. The pin is disposed along a first direction and is insertable into the insert assembly 17 through the second mold body 20 to limit movement of the insert assembly 17 when the second mold body 20 moves along the first direction, so as to allow relative movement between the slide 12 and the insert assembly 17.

In one embodiment, as shown in FIGS. 9, 13 and 15, the first mold body 10 further includes a second elastomeric member 18. A second resilient member 18 is provided between the slide 12 and the insert assembly 17. The second resilient member 18 is capable of generating a driving force that drives the insert assembly 17 in the second direction. The second resilient element 18 is configured to provide a resisting force when the first surface 22 and the second surface 171 are attached, ensure the precision of the fit between the first surface 22 and the second surface 171, and prevent the second surface 171 from separating from the first surface 22, which reduces the precision of the position of the insert assembly 17, thereby affecting the shape of the hole, recess, or boss, etc. on the injection molded part 40. Meanwhile, the second elastic part 18 is arranged to avoid rigid driving of the slide block 12 to the insert assembly 17, and flexible driving is achieved between the slide block 12 and the insert assembly 17 through the second elastic part 18, so that the phenomenon of locking caused by reduction of matching precision among the slide block 12, the insert assembly 17 and the second die body 20 due to influence of machining precision and thermal expansion and cold contraction is avoided. Specifically, when the fitting accuracy is low, the second elastic member 18 can be deformed by itself to adjust the positions of the slide 12 and the insert assembly 17, so as to avoid the occurrence of the lock-up phenomenon. In this embodiment, the second elastic member 18 is a spring, which extends in the second direction and is capable of providing a driving force in the second direction.

In one embodiment, as shown in FIGS. 9 and 14, the second mold body 20 is provided with a third surface 23. The third surface 23 is inclined away from the initial position relative to the first surface 22. Insert assembly 17 is provided with a fourth surface 172 that is parallel to third surface 23. The fourth surface 172 is capable of conforming to and sliding relative to the third surface 23 when the slider 12 slides from the third position to the first position. The insert assembly 17 can thus be driven to a predetermined position by the cooperation of the third surface 23 and the fourth surface 172 to facilitate the mating of the first surface 22 and the second surface 171. In this embodiment, the first surface 22 and the third surface 23 are integrally connected, and similarly, the second surface 171 and the fourth surface 172 are integrally connected. During mold closing, the third surface 23 and the fourth surface 172 are first attached, and the insert assembly 17 is driven to a predetermined position, so that the first surface 22 and the second surface 171 are arranged along the first direction, thereby ensuring that the first surface 22 can be attached to the second surface 171 when the second mold block 20 is subsequently moved along the first direction.

In one embodiment, as shown in fig. 9, 13-15, the insert assembly 17 includes a guide 173 and an insert 174. Second surface 171 and fourth surface 172 are formed on guide 173, insert 174 is fixed to guide 173, when slide 12 slides from the third position to the first position, first surface 22 is separated from second surface 171, at this time, third surface 23 is attached to fourth surface 172, and slide 12 can drive insert 174 to move in the second direction through guide 173. The insert 174 is fixedly mounted to the guide 173 to accommodate the formation of holes, recesses or bosses in the injection molded part 40 along the second direction.
