Description

Technical Field

[0001] The present application relates to the technical field of plastic product processing, and in particular to a cutting device for processing plastic handles. Background Art

[0002] Injection molding is a plastic manufacturing process that injects molten plastic into a mold and then cools and solidifies it. It generally includes steps such as heating and melting, filling the mold, cooling and solidifying, mold opening, and reprocessing. This method is used in the processing of plastic handles. In the related art, when injecting plastic handles, a single mold is often used to simultaneously inject multiple plastic handles, that is, a single mold is formed with multiple mold cavities, and flow channels are connected between adjacent mold cavities. By injecting molten plastic into the mold, the molten plastic can fill each mold cavity through the flow channel, thereby realizing the simultaneous molding of multiple parts.

[0003] The problem with the related technology is that after multiple parts are injection molded, the mold needs to be opened to take out the multiple parts, and the parts after being taken out need to be reprocessed. The reprocessing specifically requires manual cutting of the remaining materials at the joints of the multiple parts to separate the parts into independent individuals. The manual cutting method is not only inefficient, but also not conducive to large-scale production and manufacturing activities. Utility Model Content

[0004] In order to save labor costs and ensure the processing and manufacturing efficiency of plastic handles, the present application provides a cutting device for processing plastic handles.

[0005] The present application provides a cutting device for processing plastic handles using the following technical solution:

[0007] By adopting the above technical solution, the cylinder drives the cutting knife to open and close, so that the remaining material connecting two plastic products can be cut. The driving component is used to drive the base plate on which the cutting component is installed to move to adjust the cutting position, ensuring that the remaining material at different clamping positions on the fixture can be removed. This cutting method does not require manual participation throughout the process, has high cutting efficiency, and is suitable for large-scale production.

[0008] Optionally, a mounting seat is slidably connected to the base plate, and each of the cylinders is mounted on the mounting seat. An adjustment component is provided on the base plate, and the mounting seat is connected to the adjustment component. The adjustment component is used to adjust the distance between the two cutting knives of each group of cutting assemblies.

[0009] By adopting the above technical solution, the adjustment component adjusts the distance between the two cutting knives, which can facilitate the staff to determine the cutting position according to parameters such as the length of the remaining material to be cut, thereby ensuring the cutting quality.

[0010] Optionally, the adjustment assembly includes a nut sleeve, a screw and a connecting piece. The nut sleeve is rotatably mounted on the base plate. Two screws are provided. One end of the two screws are respectively inserted into the nut sleeves. The connecting piece is provided at the other end of the screw and connected to the mounting seat. The adjustment assembly is provided with multiple groups, and the number is the same as the number of cutting components.

[0011] By adopting the above technical solution, when the nut sleeve is rotated, the screw rod can move along its extension direction, so that the two mounting seats are moved closer to or farther away from each other, thereby adjusting the distance between the two cutting knives.

[0012] Optionally, the nut sleeve includes a sleeve body and a threaded mating portion arranged at the port of the sleeve body, the threaded mating portion is annular, and its inner side surface is formed with a thread that cooperates with the screw rod, and the outer side surface is integrally connected to the inner wall of the sleeve body. A stop piece is provided at one end of the screw rod extending into the nut sleeve, and the cross-sectional size of the stop piece is larger than the cross-sectional size of the screw rod.

[0013] By adopting the above technical solution, when the nut sleeve rotates, the screw extends out or retracts from the nut sleeve under the action of the threaded mating part, and the stop member is used to limit the extension of the screw during the extension process to prevent the screw from escaping from the nut sleeve.

[0014] Optionally, the two screw rods have the same length and are symmetrically distributed about the center line of the nut sleeve, and the center line of the nut sleeve coincides with the center line of the surplus material to be cut.

[0015] By adopting the above technical solution, it can be ensured that when the nut sleeve is rotated, the two screws can be extended or retracted to the same length at the same time, and in this process, the two mounting seats are always symmetrically distributed about the center line of the waste material to be cut, that is, the two cutting knives can accurately cut the waste material to ensure the cutting quality.

[0016] Optionally, the driving assembly includes an electric slide rail, a guide rail and two slide plates, and the electric slide rail and the guide rail are respectively distributed on both sides of the base plate, one of the slide plates is connected to the driving end of the electric slide rail, and the other slide plate is slidably connected to the guide rail, and connecting parts are respectively installed on the two slide plates, which extend vertically and are connected to the base plate.

[0017] By adopting the above technical solution, the electric slide rail drives the slide connected to its driving end to move, and the other slide slides along the guide rail. Both slides are connected to the base plate through connecting parts, so that the base plate can move with the slide, thereby moving the base plate to adjust the position of the cutting assembly.

[0018] Optionally, the connecting member includes an outer sleeve and an inner rod body, the outer sleeve is fixedly mounted on the skateboard, the inner rod body is inserted into the outer sleeve, a vertical plate is provided on the side of the base plate away from the clamp, a guide groove is provided on the vertical plate, a guide block extending into the guide groove is provided at one end of the inner rod body, and the other end is connected to the base plate.

[0019] By adopting the above technical solution, when the skateboard moves, the outer sleeve moves with the skateboard, and the inner rod body inserted in the outer sleeve moves accordingly. During the movement of the inner rod body, one end of the inner rod body rises or falls according to the shape change of the guide groove, and the other end is connected to the bottom plate and drives the bottom plate to rise or fall accordingly.

[0020] Optionally, the guide groove includes a horizontal section and inclined sections respectively arranged at both ends of the horizontal section, and ends of the two inclined sections away from the horizontal section are inclined toward a direction close to the bottom plate.

[0021] By adopting the above technical solution, when the inner rod moves from an inclined section to a horizontal section of the guide groove, the bottom plate moves away from the clamp, thereby avoiding the material product fixed on the clamp. When the inner rod moves from the horizontal section to the inclined section of the guide groove, the bottom plate approaches the clamp, so that the cutting knife can act on the remaining material to be cut on the plastic product.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The present application embodiment discloses a cutting device for processing plastic handles. Figure 1 A cutting device for processing plastic handles includes a fixture 1 for clamping and fixing a plastic product after demoulding, and a bottom plate 2 arranged parallel to the fixture 1, and a cutting assembly 3 for cutting the residual material on the plastic product is arranged on the side of the bottom plate 2 facing the fixture 1. A plurality of clamping stations 4 are formed on the fixture 1, and the plurality of clamping stations 4 are arranged in an array. Correspondingly, there are also a plurality of cutting assemblies 3 arranged on the bottom plate 2, and the number of cutting assemblies 3 is at least the same as that of the plurality of clamping stations 4 in the same row and corresponds one to one.

[0033] In some preferred embodiments of the present application, there are eight clamping stations 4, which are arranged in a 2×4 array. Each clamping station 4 clamps and fixes two plastic products, which are connected by residual material. The cutting assembly 3 is used to remove the residual material to separate the plastic products. Correspondingly, there are four groups of cutting assemblies 3, which are arranged in a 2×2 array. The two groups of cutting assemblies 3 in the same row correspond to the two clamping stations 4 in the same row, and the two groups of cutting assemblies 3 in another row correspond to the two clamping stations 4 in the third row.

[0034] Specifically, refer to Figure 1 and Figure 2The cutting assembly 3 includes two relatively distributed cylinders 31 and a cutting knife 32 installed at the driving end of the cylinder 31. The cylinder 31 can control the opening and closing of the cutting knife 32, and the residual material is cut during the opening and closing process of the cutting knife 32. Preferably, the two cylinders 31 are symmetrically distributed about the center line of the residual material to be cut.

[0035] A mounting seat 6 is slidably connected to the bottom plate 2, and the cylinder 31 is detachably fixed to the mounting seat 6. The number of mounting seats 6 is the same as the total number of cylinders 31 in the group of cutting assemblies 3. That is, when the cutting assemblies 3 are provided with four groups as described above, eight mounting seats 6 should be provided. The eight mounting seats 6 can all slide relative to the bottom plate 2, and the sliding direction is located on the straight line where the two cylinders 31 in the same group of cutting assemblies 3 are located.

[0036] Furthermore, an array of adjustment components 7 is installed on the bottom plate 2, and each group of adjustment components 7 has two moving ends, and the two moving ends are respectively connected to two mounting seats 6 for fixing the same group of cutting components 3. The adjustment component 7 can drive the two moving ends to move closer to or farther from each other, that is, drive the two mounting seats 6 to move closer to or farther from each other, and the two mounting seats 6 drive the cylinders 31 fixed thereon to move synchronously to adjust the spacing between the two cutting knives 32, and finally realize the adjustment of the length of the remaining material to be cut. As described above, when the cutting components 3 are provided with four groups, the adjustment components 7 should also be provided with four groups.

[0037] Reference Figure 3 and Figure 4 Each set of adjustment components 7 includes a nut sleeve 71 and two screw rods 72, wherein the nut sleeve 71 is rotatably installed on the base plate 2, and the nut sleeve 71 includes a sleeve body 711 and a threaded matching portion 712. The sleeve body 711 is a hollow structure with two through-holes. The threaded matching portion 712 is annular, and the inner side surface of the threaded matching portion 712 is formed with a thread matching the screw rod 72, and the outer side surface is integrally connected to the inner wall of the sleeve body 711. Two threaded matching portions 712 are provided and are located at both ends of the sleeve body 711. One end of the two screw rods 72 respectively passes through the two threaded matching portions 712 and extends into the sleeve body 711.

[0038] When the nut sleeve 71 rotates, the nut mating part rotates relative to the screw rod 72, causing the screw rod 72 to extend from or retract into the sleeve body 711. The end of the screw rod 72 away from the nut sleeve 71 is the above-mentioned moving end. When the screw rod 72 extends or retracts, it drives the mounting seat 6 to move closer to or away from the nut sleeve 71.

[0039] Furthermore, a stop member 721 is provided at one end of the screw rod 72 extending into the sleeve body 711 . The cross-sectional dimension of the stop member 721 is larger than the cross-sectional dimension of the screw rod 72 . The stop member 721 is used to limit the extension stroke of the screw rod 72 when it is extended, thereby preventing the screw rod 72 from escaping from the sleeve body 711 .

[0040] Preferably, the two screw rods 72 are of the same length, and the center line of the nut sleeve 71 coincides with the center line of the waste material to be cut, thereby ensuring that when the nut sleeve 71 rotates, the two screw rods 72 can extend or retract the same distance, so that the two mounting seats 6 are always symmetrical about the center line of the waste material to be cut when moving.

[0041] A driving assembly 5 is provided on the side of the bottom plate 2 away from the clamp 1, and the driving assembly 5 is used to drive the bottom plate 2 to move. After the four cutting assemblies 3 cut the residual materials on the clamping stations 4 in the first and third rows respectively, the bottom plate 2 needs to be moved by the driving assembly 5 so that the four cutting assemblies 3 correspond to the residual materials on the clamping stations 4 in the second and fourth rows.

[0042] Reference Figure 5 The driving assembly 5 includes an electric slide rail 51 and a guide rail 52 respectively arranged on both sides of the length direction of the bottom plate 2. A slide plate 53 is installed on the electric slide rail 51 and the guide rail 52. The slide plate 53 is connected to the bottom plate 2 through a connecting member 54. The electric slide rail 51 can drive the slide plate 53 installed thereon to move, thereby driving the bottom plate 2 to move. The electric slide rail 51 and the guide rail 52 are parallel to each other, and the extension direction of the two is the same as the length direction of the bottom plate 2. The guide rail 52 is provided to play a role of auxiliary support and guidance for the bottom plate 2.

[0043] Furthermore, the connecting member 54 includes an outer sleeve 541 and an inner rod 542 inserted in the outer sleeve 541. The outer sleeve 541 is fixed on the slide plate 53. One end of the inner rod 542 is connected to the bottom plate 2, and the other end extends vertically upward. A vertical plate 8 is arranged above the bottom plate 2. The vertical plate 8 is provided with a guide groove 9 extending along the length direction of the bottom plate 2. A guide block 10 is arranged at one end of the inner rod 542 extending upward. The guide block 10 is engaged with the guide groove 9 and can slide along the extension direction of the guide groove 9.

[0044] Furthermore, the guide groove 9 includes a horizontal section and two inclined sections arranged at both ends of the horizontal section, and the ends of the two inclined sections that are away from each other are inclined toward the direction close to the bottom plate 2.

[0045] To ensure the stability of the base plate 2 during movement, four connecting members 54 should be provided, and the four connecting members 54 are respectively arranged at the four corners of the base plate 2. Correspondingly, the number of slides 53 installed on the electric slide rail 51 is two, the number of slides 53 installed on the guide rail 52 is also two, and the number of guide grooves 9 opened on the vertical plate 8 is four.

[0046] With the above structure, when the driving assembly 5 drives the base plate 2 to move, the electric slide rail 51 drives the slide plate 53 installed thereon to move. During the movement of the slide plate 53, the outer sleeve 541 and the inner rod body 542 are driven to move. When the inner rod body 542 moves, one end of the inner rod body 542 provided with the guide block 10 moves from one end of the guide groove 9 along the inclined section, driving the other end of the guide block 10 and the base plate 2 to move accordingly. At this time, the base plate 2 is away from the fixture 1, thereby avoiding the components on the fixture 1. After that, the guide block 10 enters the horizontal section, moves along the horizontal section for a distance, and then enters another inclined section again. When moving along the inclined section, the base plate 2 approaches the fixture 1, so that the cutting assembly 3 on the base plate 2 is close to the clamping station 4 for cutting the residual material. The specific structure and driving principle of the above electric slide rail 51 are common knowledge and will not be elaborated here.

[0047] The implementation principle of a cutting device for processing plastic handles in the embodiment of the present application is as follows: initially, the four cutting assemblies 3 arranged on the bottom plate 2 correspond to the clamping stations 4 in the first and third rows respectively, and the cutting knife 32 is driven to open and close by the cylinder 31 to cut the residual material on the clamping station 4. After the residual material in the first and third rows is removed, the electric slide rail 51 drives the slide plate 53 to move, and the slide plate 53 drives the bottom plate 2 to move accordingly through the connecting member 54. During the movement of the connecting member 54, the guide block 10 slides along the guide groove 9. According to the change of the shape of the guide groove 9, the bottom plate 2 first moves away from the clamp 1, so that the cutting knife 32 avoids the components on the clamp 1, and then the bottom plate 2 moves horizontally by an end distance. When the four groups of cutting components 3 are close to the clamping stations 4 of the second and fourth rows, the guide block 10 slides to another inclined section of the guide groove 9, and the bottom plate 2 is moved close to the clamp 1 through the inner rod body 542, so that the cutting knife 32 corresponds to the part to be cut, and then the cylinder 31 controls the opening and closing of the cutting knife 32 to cut the remaining materials in the second and fourth rows.

[0048] Before cutting, when it is necessary to adjust the cutting length according to the specifications of the remaining material to be cut, the nut sleeve 71 can be rotated to make the screw 72 extend or retract from the sleeve body 711, and the screw 72 drives the two mounting seats 6 to move closer to or away from each other, and the cylinder 31 and the cutting knife 32 fixed on the mounting seats 6 move closer to or away from each other accordingly, thereby adjusting the cutting position and length.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
