DETAILED DESCRIPTION

[0031] The following will be combined with the attached Figures 1 to 9The technical solution of the present invention is described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention provides a molding die for processing plastic parts by improvement. Figure 1-Figure 9 As shown, it includes a male mold body 1, a female mold body 2 and a bottom plate 3. A limiting ring 101 is arranged on the top of the male mold body 1. A plurality of fixed seats 102 are arranged on the inner side of the limiting ring 101. The fixed seats 102 are composed of a vertical seat 103 and an arc plate 104. A symmetrical supporting leg 107 is fixedly arranged on the limiting ring 101. The male mold body 1 is fixedly mounted on the bottom plate 3 through the supporting leg 107; a plurality of positioning structures 201 are arranged on the top outer wall of the female mold body 2. The positioning structures 201 are composed of two sets of parallel locking plates 202. The female mold body 2 is fixedly mounted on the fixed seat 102 through the locking plates 202; a plurality of vertical plates 204 are arranged on the outer wall of the female mold body 2. A slide rail 205 is arranged in the middle of the vertical plate 204. The slide rail 205 5 is movably provided with a motion lock 207, and symmetrical return springs 206 are connected to both sides of the vertical plate 204, and the top of the return spring 206 is connected to the motion lock 207. When the motion lock 207 slides along the slide rail 205, the arc plate 104 and the locking plate 202 can be locked and unlocked; a bearing 218 is also provided on the outer wall of the female mold body 2, and a symmetrical support leg 220 is provided at the bottom of the bearing 218, and the female mold body 2 is slidably set on the bottom plate 3 through the support leg 220; an injection cavity 108 is formed between the male mold body 1 and the female mold body 2, and an exhaust valve 226 connected to the injection cavity 108 is also installed at the bottom of the female mold body 2, and an injection port 106 connected to the injection cavity 108 is provided on the male mold body 1.

[0033] In this embodiment: the molding die for plastic parts processing is mainly divided into three parts: male mold body 1, female mold body 2 and bottom plate 3. When the device is working, the female mold body 2 is moved along the bottom plate 3 by the second handle 219. When the positioning structure 201 is positioned between the adjacent fixed seats 102, the female mold body 2 is rotated counterclockwise by the first handle 217 to insert the arc plate 104 between the locking plates 202. Then the rotating handle 214 is rotated counterclockwise, and the boss 213 on the driving ring 212 will drive the extrusion protrusion 209 to the right and make it slide along the slide rail 205. The main part of the motion lock 207 will re-lock the space between the vertical seat 103 and the positioning structure 201, and the locking column 210 on the extrusion protrusion 209 will pass through the first slot 105 and the second slot 203 in sequence to triple lock the arc plate 104 and the locking plate 202. When the locking is completed, the molding material is injected into the injection port 106 through an external device. At this time, under the extrusion of the raw materials, the gas in the injection cavity 108 will move upward and impact the movable plug 230 outward. Under the impact of the airflow, the movable plug 230 moves outward, and the limiting portion 231 is separated from the shielding ring 227, and the gas will be discharged through the exhaust hole 233. As the airflow weakens, the movable plug 230 will gradually move inward under the action of the return spring 229. When the sensor 236 detects that the airflow intensity reaches the critical value, the second cylinder 235 will be started, and the second cylinder 235 will abut against the bottom of the movable plug 230. When the molding is completed, the second cylinder 235 will automatically retract to its original position. Then rotate the handle 214 clockwise, and the boss 213 will be separated from the extrusion protrusion 209, and the movable lock 207 will return to its original state under the action of the return spring 1 206. At this time, the main body of the moving lock 207 will be separated from the space between the vertical seat 103 and the positioning structure 201, and the locking column 210 will be separated from the first slot 105 and the second slot 203 in turn to unlock the arc plate 104 and the locking plate 202. Then, the mother mold body 2 is rotated clockwise by the first handle 217 to separate the arc plate 104 from the locking plate 202. The mother mold body 2 is moved along the bottom plate 3 by the second handle 219. When there is enough demoulding space, the first cylinder 223 is finally started.

[0034] See attached Figure 7 The motion lock 207 is also provided with a slide groove 208 that cooperates with the slide rail 205 .

[0035] In this embodiment, in order to ensure that the moving lock member 207 slides along the slide rail 205 , a slide groove 208 is provided on the moving lock member 207 .

[0036] See attached Figure 5 -Attached Figure 7A mounting protrusion 211 is provided on the outer wall of the mother mold body 2, and a driving ring 212 is rotatably provided on the mounting protrusion 211. A plurality of bosses 213 cooperating with the extrusion protrusion 209 are provided on the top of the driving ring 212, and a rotating handle 214 is provided on the side of the boss 213.

[0037] In this embodiment, in order to drive the motion lock 207 to re-lock the fixed seat 102 and the positioning structure 201, a driving ring 212 is rotatably provided on the mounting protruding ring 211. When the rotating handle 214 is rotated counterclockwise, the boss 213 will drive the squeezing protrusion 209 to the right and make it slide along the slide rail 205. When the rotating handle 214 is rotated clockwise, the boss 213 will be separated from the squeezing protrusion 209, and the motion lock 207 will be restored to its original state under the action of the return spring 1 206.

[0038] See attached Figure 5 -Attached Figure 7 A T-shaped rail 215 is provided on the top of the mounting convex ring 211 , and a T-shaped slot 216 matching with the T-shaped rail 215 is opened on the bottom of the driving ring 212 .

[0039] In this embodiment, when the driving ring 212 rotates relative to the mounting protruding ring 211 , in order to further improve the stability during rotation, a T-shaped groove 216 cooperating with the T-shaped rail 215 is opened at the bottom of the driving ring 212 .

[0040] See attached Figure 2 -Attached Figure 3 A demoulding hole 224 is provided at the bottom of the mother mold body 2, and a support frame 222 is also installed at the bottom of the mother mold body 2. A first cylinder 223 is installed on the support frame 222, and an output end of the first cylinder 223 is connected to a demoulding plate 225 that cooperates with the demoulding hole 224.

[0041] In this embodiment, after molding and when the female mold body 2 is separated from the male mold body 1 , in order to facilitate demoulding, a first cylinder 223 is installed on the support frame 222 .

[0042] See attached Figure 1 -Attached Figure 2 The outer wall of the mother mold body 2 is provided with multiple groups of first handles 217, and the outer side of the bearing 218 is provided with multiple groups of second handles 219.

[0043] In this embodiment, in order to facilitate locking and unlocking of the mother mold body 2, thereby realizing molding and demolding, handles are provided on the outer wall of the mother mold body 2 and the outer side of the bearing 218. When locking is required, the mother mold body 2 is moved along the bottom plate 3 by the second handle 219. When the positioning structure 201 is positioned between adjacent fixing seats 102, the mother mold body 2 is rotated counterclockwise by the first handle 217 to insert the arc plate 104 between the locking plates 202.

[0044] See attached Figure 8 -Attached Fig. 9 A shielding ring 227 is provided at the top of the exhaust valve 226, and a plurality of groups of convex plates 228 are provided on the inner wall of the exhaust valve 226. The top of the convex plate 228 is connected with a return spring 229, and the top of the return spring 229 is connected with a movable plug 230; the movable plug 230 consists of a limiting portion 231 and a protruding portion 232. The limiting portion 231 is provided with a plurality of groups of exhaust holes 233. A connecting plate 234 is provided between the convex plates 228, and a second cylinder 235 cooperating with the movable plug 230 is installed in the middle of the connecting plate 234. A sensor 236 is also installed at the bottom of one group of convex plates 228.

[0045] In this embodiment: In order to prevent the gas in the injection cavity 108 from affecting the molding effect, an exhaust valve 226 connected to the injection cavity 108 is installed at the bottom of the mother mold body 2. When the molding material is injected into the injection port 106 through an external device, the gas in the injection cavity 108 will move upward and impact the movable plug 230 outward under the extrusion of the raw material. Under the impact of the airflow, the movable plug 230 moves outward, at which time the limit part 231 is separated from the shielding ring 227, and the gas is discharged through the exhaust hole 233. As the airflow weakens, the movable plug 230 will gradually move inward under the action of the return spring 229. When the sensor 236 detects that the airflow intensity reaches the critical value, the second cylinder 235 will be started. At this time, the second cylinder 235 abuts against the bottom of the movable plug 230, thereby preventing the movable plug 230 from being displaced and affecting the molding effect under the impact of the molding material.

[0046] See attached Figure 1 -Attached Figure 2 A symmetrical T-slot 2 301 is provided on the bottom plate 3 , and a sliding seat 221 matching with the T-slot 2 301 is provided at the bottom of the supporting leg 220 .

[0047] In this embodiment, when the mother mold body 2 slides along the bottom plate 3 , in order to further improve the stability, a sliding seat 221 cooperating with the second T-slot 301 is provided at the bottom of the second supporting leg 220 .

[0048] See attached Figure 8 -Attached Fig. 9 The protrusion 232 is flush with the inner wall of the mother mold body 2, and a filter screen 237 is also installed at the bottom of the exhaust valve 226.

[0049] In this embodiment, in order to prevent the exhaust valve 226 from affecting the flatness of the mold during molding, the protrusion 232 is flush with the inner wall of the mother mold body 2. The exhaust valve 226 is located above the mother mold body 2, and can be set at the bottom or the top position, because the injection port 106 is located in the middle, so that excess gas can be exhausted as much as possible.

[0050] The working principle of the present invention is as follows: when the device is working, the second handle 219 is used to move the mother mold body 2 along the bottom plate 3. When the positioning structure 201 is positioned between the adjacent fixed seats 102, the first handle 217 is used to rotate the mother mold body 2 counterclockwise to insert the arc plate 104 between the locking plates 202. Then the rotating handle 214 is rotated counterclockwise, and the boss 213 on the driving ring 212 drives the extrusion protrusion 209 to the right and slide along the slide rail 205. The main body of the moving lock 207 will re-lock the space between the vertical seat 103 and the positioning structure 201, and the locking column 210 on the extrusion protrusion 209 will pass through the first slot 105 and the second slot 203 in sequence to triple-lock the arc plate 104 and the locking plate 202. When the locking is completed, the molding raw material is injected into the injection port 106 through an external device. At this time, under the extrusion of the raw material, the gas in the injection cavity 108 will move upward and impact the moving plug 230 outward. Under the impact of the airflow, the movable plug 230 moves outward, and the limiting part 231 is separated from the shielding ring 227, and the gas will be discharged through the exhaust hole 233. As the airflow weakens, the movable plug 230 will gradually move inward under the action of the return spring 229. When the sensor 236 detects that the airflow intensity reaches the critical value, the second cylinder 235 will be activated, and the second cylinder 235 will abut against the bottom of the movable plug 230. When the molding is completed, the second cylinder 235 will automatically retract to its original position. Then rotate the handle 214 clockwise, and the boss 213 will be separated from the extrusion convex block 209, and the motion lock 207 will be restored to its original state under the action of the return spring 1 206. At this time, the main part of the motion lock 207 will be separated from the space between the vertical seat 103 and the positioning structure 201, and the locking column 210 will also be separated from the first slot 105 and the second slot 203 in turn and unlock the arc plate 104 and the locking plate 202. Then, the first handle 217 is used to rotate the mother mold body 2 clockwise to separate the arc plate 104 from the locking plate 202. The second handle 219 is used to move the mother mold body 2 along the bottom plate 3. When there is enough demoulding space, the first cylinder 223 is finally started.

[0051] The present invention can quickly locate and lock the female mold body 2 through the cooperation of the fixed seat 102 and the positioning structure 201, and when the driving ring 212 rotates, the boss 213 will squeeze the motion lock 207 to the right, wherein the main part of the motion lock 207 will re-lock the space between the vertical seat 103 and the locking plate 202. And the locking column 210 on the extrusion convex block 209 will sequentially pass through the first slot 105 and the second slot 203 to triple lock the arc plate 104 and the locking plate 202. The structure is stable and effective and brings unexpected technical effects, and also reduces the time cost and labor cost of the molding mold for plastic parts processing. The present invention can freely move and rotate the female mold body 2 through the cooperation of the bearing 218 and the supporting leg 220, so as to quickly lock and unlock it with the male mold body 1, and the cooperation of the exhaust valve 226 and the stripping plate 225 can improve the molding effect and facilitate demoulding. When injecting material into the injection cavity 108, excess air in the injection cavity 108 will be discharged through the exhaust hole 233, and when the sensor 236 detects that the flow rate is significantly reduced, it will drive the second cylinder 235 to drive the movable plug 230 to its original position, thereby preventing the raw material from leaking through the exhaust valve 226 and affecting the molding effect. This design further improves the practicability of the molding mold for plastic parts processing.
