Description

Technical Field

[0001] The invention relates to the technical field of injection molds, and in particular to a stripping mechanism; meanwhile, the invention also relates to an injection mold provided with the stripping mechanism. Background Art

[0002] In conventional injection molds, the rubber material is injected from the injection port, distributed and injected into various injection points through the runner plate, flows into the cavity through the injection points, and is cooled in the cavity plate to solidify the product. During this process, a certain amount of injection molding material will be cooled and solidified in the runner plate, forming discarded material heads. During the production process, each mold production will produce material heads, which need to be removed to ensure the smooth flow of the runner plate before the next production can be carried out.

[0003] At present, the industry generally adopts manual removal of the material head. In the specific operation, it is necessary to first separate the runner plate and the mounting seat on the mold. At this time, the material head is located in the runner plate, and then the top of the material head is held and an upward force is applied to the material head to pull the material head out of the runner plate. Obviously, the entire material head pulling action is more, and the process of pulling the material head upward is also more laborious, which is not conducive to improving production efficiency. Summary of the invention

[0004] In view of this, the present invention aims to provide a peeling mechanism to facilitate improving the convenience of stripping the material head.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] A stripping mechanism comprises a clamping part arranged on a mounting seat on a mold, the clamping part has a cavity, the cavity is connected to a flow channel of a flow channel plate in the mold, and the rubber entering the cavity can form a clamping head connected to a material head in the flow channel;

[0007] The mounting seat on the mold is driven by external force to drive the clamping portion away from the flow channel plate, and the material head is pulled out from the flow channel through the clamping head.

[0008] Furthermore, it also includes a stripping portion provided on the mounting seat on the mold through a connecting portion, the blocking portion passes through the stripping portion, the blocking portion passes through the stripping portion, and the connecting portion has a first state in which the stripping portion is close to the blocking portion, and a second state in which the stripping portion is away from the blocking portion;

[0009] As the mounting seat on the mold drives the clamping portion and the stripping portion to rise, the stripping portion switches from the first state to the second state, and ejects the clamping head from the cavity.

[0010] Furthermore, the stripping portion is connected to the flow channel plate through a pull rod, and the stripping portion can slide relative to the pull rod and rise with the mounting seat on the mold before the flow channel plate; when the stripping portion rises with the mounting seat on the mold, the stripping portion is in the first state, and when both the stripping portion and the flow channel plate rise with the mounting seat on the mold, the stripping portion is in the second state.

[0011] Furthermore, the stripping portion includes a stripping plate arranged below the mold upper mounting seat; the connecting portion includes connecting components arranged on two opposite sides of the stripping plate, and the connecting components on each side include a wedge block slidably arranged on the mold upper mounting seat, and an elastic member arranged between the wedge block and the mold upper mounting seat, and the stripping plate is clamped between the wedge blocks on both sides.

[0012] Furthermore, the elastic member includes a spring arranged between the mounting seat on the mold and the wedge block.

[0013] Furthermore, a guide portion is provided between the mold upper mounting seat and the stripping portion, and the guide portion is used to guide the stripping portion to slide relative to the mold upper mounting seat.

[0014] Furthermore, the clamping portion includes a clamping column protruding below the upper mounting seat of the mold, and the cavity is formed on the clamping column; and the cross-section of the cavity gradually decreases in a direction away from the upper mounting seat of the mold.

[0015] Furthermore, it also includes a driving part and a pushing end arranged at the power output end of the driving part; the driving part can drive the pushing end to move and push the material head and the clamping head out of the mold after escaping from the cavity.

[0016] Furthermore, the driving part includes a cylinder arranged on a mounting seat on the mold, and a push plate is provided at the telescopic end of the cylinder, and the push plate constitutes the push end.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The stripping mechanism described in the present invention is that a clamping portion is arranged on a mounting seat on the mold, and the clamping portion has a cavity connected to the flow channel of the flow channel plate, which is conducive to forming a clamping head connected to the material head in the flow channel in the cavity. When the mounting seat on the mold is driven by external force, the clamping portion can be driven away from the flow channel plate, and the material head can be pulled out of the flow channel through the clamping head, which is conducive to the automatic separation of the material head and the flow channel plate. At this time, manually applying downward force can make the clamping head fall out of the cavity and realize the stripping of the material head, which is conducive to improving the convenience of stripping the material head and helping to improve production efficiency.

[0019] In addition, the connection part has a first state in which the stripping part is close to the stuck part, and a second state in which the stripping part is far away from the stuck part, which is not only beneficial to the flow of the rubber and the molding of the product, but also beneficial to the separation of the material head from the flow channel plate, and beneficial to reducing the operation steps of manually stripping the material head. The provision of a pull rod facilitates the separation of the flow channel plate and the material head, and also facilitates the switching of the stripping part between the first state and the second state. The provision of the wedge block and the elastic member facilitates the use effect of the stripping plate in the first state, and can make the stuck head escape from the stuck part by virtue of the downward movement of the stripping plate, thereby facilitating the automatic separation of the material head and the stripping plate, further improving the efficiency and safety of the material head separation.

[0020] In addition, the spring product is mature and easy to arrange and implement. It has a good coordination effect with the wedge block, which is conducive to the wedge block approaching or moving away from the stripping plate, and then the stripping plate applies a downward force to the material head, and makes the clamping head disengage from the clamping column, so as to automatically strip the material head. By setting up a guide part, it is beneficial to improve the stability of the stripping part during sliding. The structure of the clamping column is simple, so that the cross-section of the cavity gradually decreases in the direction away from the mounting seat on the mold, which is beneficial to improve the connection effect between the clamping column and the clamping head, and ensure that the material head and the clamping column remain connected when the runner plate is separated from the material head. By setting up a drive part to eject the material head and the clamping head to the outside of the mold, it is beneficial to further improve the cleaning effect of the material head, thereby improving the continuity of the use of the mold. The cylinder product is mature and easy to arrange and implement, and the push plate is conducive to ensuring the ejection effect of the material head.

[0021] In addition, another object of the present invention is to provide an injection mold, wherein the injection mold is provided with the stripping mechanism as described above.

[0022] The injection mold of the present invention is advantageous in improving the stripping convenience of the material head by providing the stripping mechanism as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0050] Embodiment 1

[0051] This embodiment relates to a stripping mechanism to solve the technical problem in the prior art that the material head 3 is complicated and difficult to operate during the stripping process, which is not conducive to stripping.

[0052] In terms of overall structure, the stripping mechanism described in this embodiment includes a clamping portion provided on the mold upper mounting seat 1, the clamping portion having a cavity 1032, the cavity 1032 being connected to the flow channel 201 of the flow channel plate 2 in the mold, and the rubber material entering the cavity 1032 can form a clamping head 303 connected to the material head 3 in the flow channel 201. The mold upper mounting seat 1 is driven by an external force, which can drive the clamping portion away from the flow channel plate 2, and pull the material head 3 out of the flow channel 201 through the clamping head 303.

[0053] The stripping mechanism described in this embodiment is that a clamping part is provided on the mold upper mounting seat 1, and the clamping part has a cavity 1032, which is conducive to forming a clamping head 303 connected to the material head 3 in the flow channel 201 in the cavity 1032. When the mold upper mounting seat 1 is driven by an external force, it can drive the clamping part away from the flow channel plate 2, and pull the material head 3 out of the flow channel 201 through the clamping head 303, which is conducive to the automatic separation of the material head 3 and the flow channel plate 2. At this time, manually applying force downward can make the clamping head 303 escape from the cavity 1032, so as to facilitate the stripping of the material head 3 and the mold upper mounting seat 1, thereby facilitating the convenience of stripping the material head 3 and improving production efficiency.

[0054] Based on the above overall introduction, an exemplary structure of the peeling mechanism described in this embodiment is as follows: Figures 1 to 4 As an example, the mold may be a sealing strip corner mold, and the structure of the material head 3 is Figure 5 As shown in the figure, the material head 3 has a main body part 301 located in the flow channel 201, a top part 302 connected to the main body part 301 and located in the glue injection port 107, and a bottom part 304 located in the glue injection point and connected to the bottom of the main body part 301. The clamping head 303 is specifically connected to the top of the main body part 301 and is arranged corresponding to at least part of the glue injection port 107.

[0055] The shape of the main body 301 is adapted to the shape of the flow channel 201, and the number of the bottom parts 304 is adapted to the number of the injection points. The bottom parts 304 can be located at multiple ends of the main body 301. Of course, in specific implementation, the structural form of the material head 3 can also be adaptively adjusted according to the use requirements.

[0056] like Figure 1 As shown in , the mold upper mounting seat 1 includes an upper mounting plate 101 and a lower mounting plate 102 stacked together, and the above-mentioned blocking portion is specifically arranged on the lower mounting plate 102. In order to facilitate the installation of the lower mounting plate 102 on the upper mounting plate 101, a mounting assembly 6 is provided between the upper mounting plate 101 and the lower mounting plate 102. The mounting assembly 6 includes a first mounting plate 601 provided at both ends of the upper mounting plate 101, and a first mounting plate 601 inserted into the inner side of each first mounting plate 601. A mounting groove is formed between the first mounting plate 601, the second mounting plate 602 and the upper mounting plate 101. The two ends of the lower mounting plate 102 are respectively inserted into the corresponding mounting grooves, so as to be fixed on the upper mounting plate 101.

[0057] In order to facilitate the installation and removal of the second mounting plate 602, an operating block 6021 for hand-holding is provided at one end of the second mounting plate 602. Of course, in the specific implementation, in addition to the upper mounting plate 101 and the lower mounting plate 102 being connected in a coordinated manner, other connection forms can also be adopted between the upper mounting plate 101 and the lower mounting plate 102, as long as the use requirements are met.

[0058] like Figures 7 to 12 As shown in the figure, the clamping part includes a clamping column 103 protruding below the mold upper mounting seat 1, and a cavity 1032 is formed on the clamping column 103. The cross section of the cavity 1032 gradually decreases in the direction away from the mold upper mounting seat 1. Here, the structure of the clamping column 103 is simple, so that the cross section of the cavity 1032 gradually decreases in the direction away from the mold upper mounting seat 1, which is conducive to improving the connection strength between the clamping column 103 and the clamping head 303. When the runner plate 2 is separated from the material head 3, the material head 3 and the clamping column 103 still maintain a relatively stable connection relationship without separation.

[0059] Specifically, in this embodiment, the clamping column 103 is located at the bottom of the lower mounting plate 102 and is arranged one-to-one with each injection point, so that the clamping head 303 is arranged one-to-one with each bottom part 304, thereby facilitating the connection stability between the material head 3 and the mounting seat 1 on the mold. The clamping column 103 is in the shape of a truncated cone with the small diameter end facing downward, and the clamping column 103 includes two split bodies 1031 that are connected by buckling, and the bottom of each split body 1031 has a sub-cavity, and the two sub-cavities in the connected state constitute the above-mentioned cavity 1032.

[0060] like Figure 5 As shown in the figure, the clamp head 303 is arranged in accordance with the shape of the cavity 1032, and the cross section of the clamp head 303 is arranged to gradually decrease in the direction away from the lower mounting plate 102. In this way, when the material head 3 is separated from the flow channel plate 2, it is difficult for multiple clamp heads 303 to be separated from the corresponding cavity 1032, thereby ensuring the separation effect of the material head 3 and the flow channel plate 2.

[0061] As a preferred embodiment, the stripping mechanism in this embodiment also includes a stripping portion provided on the mold upper mounting seat 1 through a connecting portion, and the blocking portion passes through the stripping portion. The blocking portion passes through the stripping portion, and the connecting portion has a first state in which the stripping portion is close to the blocking portion, and a second state in which the stripping portion is far away from the blocking portion. As the mold upper mounting seat 1 drives the blocking portion and the stripping portion to rise, the stripping portion switches from the first state to the second state, and ejects the clamping head 303 from the cavity 1032. Such a configuration is not only conducive to the flow of the rubber through the runner plate 2 and the molding of the product, but also conducive to the separation of the material head 3 from the runner plate 2, and is conducive to reducing manual operation steps.

[0062] In this embodiment, when the connecting portion is in the first state, the structure of the peeling mechanism is as follows: Figure 1As shown in FIG. , when the connecting portion is in the second state, the structure of the peeling mechanism is as follows: Figures 2 to 4 In the first state, the stripping mechanism is in the injection state, at which time the glue is injected from the glue injection port 107 on the mold mounting seat 1 and flows into the flow channel 201 on the flow channel plate 2, and flows into the cavity 1032 and the cavity plate through the flow channel 201 and the glue injection port 107 to form the product and form the above-mentioned material head 3 and the clamping head 303.

[0063] The mounting seat 1 on the mold is driven by an external force to drive the clamping part away from the flow channel plate 2, and the material head 3 is pulled out from the flow channel 201 through the clamping head 303, and switched to the second state, the material head 3 is suspended on the clamping part through the clamping head 303, and the main body 301 and the bottom part 304 of the material head 3 are both located above the flow channel plate 2 and between the clamping part. At this time, the clamping head 303 can be separated from the clamping part by applying a downward force to the material head 3, so that the material head 3 can be removed easily.

[0064] Since the main body 301 has been separated from the flow channel plate 2, the material head 3 can be separated from the stuck part by applying a downward force to the bottom of the material head 3. Compared with the traditional solution, after the mounting seat 1 on the mold is separated from the flow channel plate 2, the material head 3 is still located in the flow channel 201 and can only be separated by pulling the material head 3 upward. The peeling mechanism of this embodiment has the advantages of easy operation and high separation efficiency.

[0065] As a preferred embodiment, the stripping part is connected to the flow channel plate 2 through the tie rod 401, and the stripping part can slide relative to the tie rod 401, and rises with the mold upper mounting seat 1 before the flow channel plate 2. When the stripping part rises with the mold upper mounting seat 1, the stripping part is in the first state, and when the stripping part and the flow channel plate 2 both rise with the mold upper mounting seat 1, the stripping part is in the second state. The provision of the tie rod 401 facilitates the separation of the flow channel plate 2 and the material head 3, and facilitates the stripping part to switch between the first state and the second state.

[0066] In terms of specific structure, Figures 6 to 10 As shown in the figure, the stripping part includes a stripping plate 4 disposed below the mold upper mounting seat 1. The connecting part includes connecting components disposed on two opposite sides of the stripping plate 4, each side connecting component includes a wedge block 402 slidably disposed on the mold upper mounting seat 1, and an elastic member 403 disposed between the wedge block 402 and the mold upper mounting seat 1, and the stripping plate 4 is sandwiched between the wedge blocks 402 on both sides. Here, the arrangement of the wedge block 402 and the elastic member 403 is conducive to the use effect of the stripping plate 4 in the first state, and the downward movement of the stripping plate 4 can make the clamping head 303 escape from the clamping part, thereby facilitating the automatic separation of the material head 3 and the stripping plate 4, and further improving the efficiency and safety of the separation of the material head 3.

[0067] In detail, the tie rod 401 is extended in the up-down direction so that the flow channel plate 2 and the stripping part can slide in the up-down direction relative to the mold upper mounting seat 1. The wedge block 402 is slidably arranged along the length direction of the mold upper mounting seat 1, and the tie rod 401 is specifically arranged on two opposite sides of the stripping plate 4 and the flow channel plate 2 in the length direction. Among them, two tie rods 401 are arranged on each side of the stripping plate 4 and the flow channel plate 2. In order to facilitate the arrangement of the tie rod 401, the side portions of the stripping plate 4 and the flow channel plate 2 are respectively provided with protruding connection blocks 4011, the top of the tie rod 401 is fixedly arranged with the connection block 4011 arranged on the top, and the tie rod 401 is arranged through the connection block 4011 at the bottom.

[0068] Combination Fig.13 As shown in , in order to facilitate the passage of the blocking portion from the stripping portion, corresponding to each clamping column 103, a through hole 406 for each clamping column 103 to pass through is provided on the stripping plate 4, thereby facilitating the connection between the mold cavity 1032 and the flow channel 201, and further facilitating the molding effect of the clamping head 303. Figure 1 As shown in the figure, in the first state, the stripping plate 4 and the flow channel plate 2 are stacked together, the bottom surface of the stripping plate 4 and the flow channel 201 define a cavity, the upper and lower connecting blocks 4011 are also stacked together, and the clamping columns 103 are respectively inserted into the corresponding through holes 406.

[0069] To facilitate the installation of the wedge block 402, as Fig.10 and Fig.14 As shown in the figure, the inner sides of both ends of the lower mounting plate 102 are respectively provided with downwardly convex blocks 106, and the bottom of the convex blocks 106 is provided with mounting blocks 104. The mounting blocks 104 and the convex blocks 106 are provided with sliding grooves on the inner side, and the wedge blocks 402 are specifically slidably arranged in the sliding grooves. In order to ensure the sliding effect of the wedge blocks 402, guide grooves 1041 are respectively provided on both sides of the sliding grooves, and guide blocks 4022 located in the guide grooves 1041 are respectively provided on both sides of the wedge blocks 402.

[0070] The elastic member 403 of this embodiment includes a spring disposed between the mounting seat 1 on the mold and the wedge block 402. The spring product is mature, easy to arrange and implement, and has a good matching effect with the wedge block 402, which is conducive to the wedge block 402 approaching or moving away from the stripping plate 4, thereby improving the stripping effect between the stripping plate 4 and the material head 3. In terms of specific structure, Figure 7 and Fig.14 As shown in , two springs are provided between the bottom of the slide groove and the end of the wedge block 402 , which helps to improve the stability of the wedge block 402 during use.

[0071] Corresponding to the protrusion 106 and the mounting block 104, the combination Fig. 9 and Fig.13As shown in FIG. 4 , notches 405 are respectively provided at both ends of the stripping plate 4. In the first state, the protrusion 106 and the mounting block 104 are both located in the notches 405. Corresponding to the inclined surface on the wedge block 402, a matching block 404 is provided on the side wall of the notch 405 to abut against the wedge block 402, and the matching block 404 also has an inclined surface. For the convenience of distinction, the inclined surface on the wedge block 402 is referred to as the first inclined surface 4021, and the inclined surface on the matching block 404 is referred to as the second inclined surface 4041. Specifically, the wedge block 402 clamps the stripping plate 4 between the two wedge blocks 402 by abutting the first inclined surface 4021 and the second inclined surface 4041.

[0072] In the first state, the contact area between the first inclined surface 4021 and the second inclined surface 4041 is the largest, and the distance between the two wedge blocks 402 is the smallest, that is, the clamping force of the two wedge blocks 402 on the stripping plate 4 is the largest. When the second inclined surface 4041 moves downward relative to the first inclined surface 4021, the wedge blocks 402 can be pressed outward by the first inclined surface 4021 and the spring can be compressed. At this time, the distance between the two wedge blocks 402 gradually increases, that is, the clamping force of the two wedge blocks 402 on the stripping plate 4 gradually decreases. When the distance between the two wedge blocks 402 is the largest, the distance between the bottoms of the two first inclined surfaces 4021 is smaller than the distance between the tops of the two second inclined surfaces 4041, thereby preventing the stripping plate 4 from being separated from the lower mounting plate 102, and further facilitating the use effect of the stripping plate 4 in the first state and the second state.

[0073] It should be noted that, in addition to the wedge block 402 and the spring, the connection portion in this embodiment can also use a driving device capable of outputting a linear driving force. In this case, the power output end of the driving device is connected to the stripping plate 4, and the stripping plate 4 is driven to move downward relative to the lower mounting plate 102, so that the material head 3 can be separated. Moreover, compared with the solution of setting a driving device, the cooperation between the wedge block 402 and the spring in this embodiment is conducive to reducing production costs and is easy to arrange and implement.

[0074] Furthermore, a guide portion is provided between the mold upper mounting seat 1 and the stripping portion, and the guide portion is used to guide the stripping portion to slide relative to the mold upper mounting seat 1. Specifically, the guide portion specifically guides the stripping plate 4 to slide up and down relative to the lower mounting plate 102, which is conducive to improving the stability of the stripping plate 4 in the up and down sliding. Fig.10 As shown in the figure, the guide part includes a plurality of guide posts 105 disposed on the top of the stripping plate 4 and a plurality of guide holes disposed on the lower mounting plate 102. The guide posts 105 slide in the corresponding guide holes to guide the stripping plate 4 to slide up and down relative to the lower mounting plate 102. In specific implementation, the number and position of the guide posts 105 can be adjusted according to the use requirements.

[0075] In addition, the stripping mechanism of this embodiment also includes a driving unit and a push end provided at the power output end of the driving unit. The driving unit can drive the push end to move and push the material head 3 and the clamping head 303 out of the mold after being out of the cavity 1032. Obviously, the clamping head 303 is connected to the material head 3, and the material head 3 and the clamping head 303 are pushed out of the mold by setting the driving unit, which is conducive to further improving the cleaning effect of the material head 3, thereby improving the continuity of the use of the mold.

[0076] As a preferred embodiment, Figure 2 As shown in , the driving part includes a cylinder 5 arranged on the mounting seat 1 on the mold, and a push plate 502 is provided at the telescopic end of the cylinder 5, and the push plate 502 constitutes a push end. Among them, the telescopic end of the cylinder 5 is specifically the free end of the cylinder rod 501, and the push plate 502 can push the material head 3 above the runner plate 2, thereby facilitating the cleaning efficiency of the material head 3 and realizing automatic cleaning of the material head 3.

[0077] In specific implementation, the driving part is fixed to a preset position on one side of the mounting seat 1 on the mold through the mounting structure. When the mounting seat 1 on the mold moves upward to the preset position and the material head 3 falls on the runner plate 2, the mounting seat 1 on the mold stops moving upward, and the push plate 502 is driven by the cylinder 5 to move, so that the material head 3 and the clamping head 303 can be pushed out of the runner plate 2. The product of the cylinder 5 is mature and easy to arrange and implement, and the push plate 502 is conducive to ensuring the ejection effect of the material head 3. Furthermore, a waste box larger than the driving part can be set relatively, and the waste box is located on the falling path of the material head 3 to collect the material head 3, thereby improving the collection efficiency of the material head 3 and reducing labor input.

[0078] When the stripping mechanism in this embodiment is in use, after the product is formed, the driving device on the mold drives the mold mounting seat 1 to move upward. At this time, the gravity of the stripping plate 4 is less than the clamping force of the two wedge blocks 402. Under the clamping action of the two wedge blocks 402, the stripping plate 4 can move upward with the mold mounting seat 1. As the flow channel plate 2 slides downward and separates from the stripping plate 4, the material head 3 can be automatically separated from the flow channel 201 and suspended on the clamping column 103. At this time, the main part 301 of the material head 3 is located at the bottom of the stripping plate 4 and can move upward with the mold mounting seat 1.

[0079] As the mold upper mounting seat 1 continues to move upward, when the gravity of the stripping plate 4 and the flow channel plate 2 is greater than the clamping force of the two wedge blocks 402, the stripping plate 4 drives the flow channel plate 2 to slide downward relative to the mold upper mounting seat 1, and the second inclined surface 4041 moves downward relative to the first inclined surface 4021 and presses the wedge block 402 outward through the first inclined surface 4021. At this time, the elastic member 403 is compressed and stored, and the distance between the two first inclined surfaces 4021 increases until the stripping plate 4 is separated from the lower mounting plate 102.

[0080] When the stripping plate 4 moves downward, it presses down the main part 301 of the material head 3, so that the clamping head 303 is ejected from the corresponding cavity 1032, and then the material head 3 is separated from the clamping column 103, and the material head 3 falls on the top of the flow channel plate 2. Finally, the cylinder 5 is started and the material head 3 falling on the flow channel plate 2 is ejected by the push plate 502, and finally the material head 3 falls into the waste box, and the cylinder 5 drives the push plate 502 to return to its position.

[0081] The stripping mechanism described in this embodiment, through the inner cavity 1032 of the clamping column 103, and the arrangement of the wedge block 402 and the spring in the connecting assembly, can switch between a first state of forming and a second state of separation of the material head 3 during the movement of the mounting seat 1 on the mold, thereby meeting the forming requirements of products such as sealing strip joints, and making the stripping of the material head 3 more automated, thereby helping to reduce labor input, reduce the risks brought by manual operation, and improve product production efficiency.
