Description

Technical Field

[0001] The utility model belongs to the field of mechanical technology, and in particular relates to a nozzle punching tool. Background Art

[0002] In recent years, with the rapid improvement of economic level, users' consumption demand for various products has gradually become stronger, especially some products with plastic shells. According to different appearance requirements, corresponding molds need to be designed to perform injection molding and obtain injection molded parts with corresponding appearance.

[0003] In the field of injection molding, an injection molding machine is usually used to prepare and obtain an injection material with a sprue by one-time injection molding; for such an injection material, it is often necessary to manually perform a shearing operation to remove the sprue in order to obtain an injection material that can be used normally.

[0004] However, research has found that due to the various shapes of plastic shells and the fact that after injection molding, the sprue is usually in the inner cavity of the plastic shell, if you want to manually cut the sprue, you need to insert scissors into the inner cavity of the shell, which is difficult to operate and has poor stability when manually cutting the sprue. Especially when facing some small-cavity injection molded parts, it is difficult for operators to insert scissors to cut the sprue, which often damages the injection-molded shell and results in poor yield. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a new nozzle punching tool to solve the problem that the nozzle located in the inner cavity of the shell injection molded part cannot be simply and quickly cut by the existing manual shearing.

[0006] In order to solve the above-mentioned technical problems, the utility model discloses a sprue punching tool, which includes a base plate, a punching component, a driving component and a material placement mold. The material placement mold is arranged on the base plate, and the material placement mold is used to place injection molded parts with sprues.

[0007] Furthermore, in the nozzle punching tool described in the utility model, a through cavity is opened in the material placement mold, the nozzle of the injection molding part with nozzle extends into the through cavity, and the punching component is arranged through the through cavity.

[0008] Currently, due to the various shapes of plastic shells, and after injection molding, the sprue is usually in the shell cavity of the plastic shell, especially when facing some small-cavity injection molded parts, if the operator wants to use manual shearing operation to remove the sprue, the operation is difficult for the operator and it is easy to damage the injection-molded shell.

[0009] Therefore, in the present utility model, the inventor has designed a new sprue punching tool, which can effectively replace manual punching of the sprue of the injection molded part. It can arrange the injection molded part with a sprue, which has a shell shape and an inner cavity, on the material placement mold, so that the sprue of the injection molded part with a sprue can extend into the through cavity of the material placement mold, and use the punching component arranged through the through cavity to punch out the sprue in the inner cavity of the shell of the injection molded part with a sprue. It is easy to operate and will not damage the injection molded part with a sprue, thereby greatly improving production efficiency, reducing the workload of operators, and improving production yield.

[0010] Furthermore, in the nozzle punching tool described in the utility model, the punching assembly includes a base and a punching knife arranged on the base, the punching knife extends along a second direction, and the second direction has an angle with the first direction.

[0011] Furthermore, in the sprue punching tooling described in the utility model, an installation groove and a first locking hole arranged through the installation groove are provided in the base, one end of the punching knife is inserted into the installation groove, and a second locking hole is arranged through the punching knife, so that the pin passes through the first locking hole and the second locking hole in sequence for locking and fixing.

[0013] Furthermore, in the nozzle punching tool described in the utility model, a limiting groove is provided on the base, and at least one limiting member passes through the material placement mold and is inserted into the limiting groove.

[0014] Furthermore, in the nozzle punching tool described in the utility model, the base is an "L"-shaped base.

[0015] Furthermore, in the nozzle punching tool described in the utility model, the first direction is the horizontal length direction of the substrate, and the second direction is the vertical height direction of the substrate.

[0016] Furthermore, in the nozzle punching tool described in the utility model, the driving mechanism includes a driving member and a driving rod, the output end of the driving member is connected to one end of the driving rod, and the other end of the driving rod is connected to the base.

[0017] Furthermore, in the nozzle punching tool described in the utility model, the driving component is a motor or a cylinder.

[0018] The beneficial effect of the utility model is that the utility model optimizes the design of a new nozzle punching tool. A major feature of the nozzle punching tool is that an injection molded part with a shell shape and an inner cavity is arranged on a material placement mold, so that the nozzle of the injection molded part can extend into the through cavity of the material placement mold, and the nozzle in the shell inner cavity of the injection molded part is punched out by using a punching assembly arranged in the through cavity.

[0032] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0033] Please refer to Figures 1 to 6 As shown, the utility model designs a new nozzle punching tool, which specifically includes a base plate 1, a punching assembly 2, a driving assembly 3 and a material placement mold 4; wherein the material placement mold 4 is fixedly arranged on the base plate 1, and the material placement mold 4 is used to place an injection molded part 5 with a nozzle (such as Figure 3 As shown), the punching assembly 2 is arranged through the material placement mold 4, and the driving assembly 3 is connected to the punching assembly 2 to drive the punching assembly 2 to move along the first direction (the horizontal length direction of the substrate 1).

[0034] Accordingly, if Figure 3 and Figure 6 As shown, in the present embodiment, a through cavity 41 is provided in the material placement mold 4, and the through cavity 41 is a special-shaped through cavity 41, and the through cavity 41 includes a first opening 411 and a second opening 412; the first opening 411 is provided on the upper top surface of the material placement mold 4, and the second opening 412 is provided on the side surface of the material placement mold 4; wherein, when the injection molded part 5 with a sprue is actually placed on the material placement mold 4 for matching, the sprue 51 of the injection molded part 5 with a sprue can extend from the first opening 411 into the through cavity 41 of the material placement mold 4.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, the punching assembly 2 designed is arranged through the material placement mold 4, and the punching assembly 2 specifically includes a base 21 and a punching knife 22 arranged on the base 21, and the punching knife 22 extends along the second direction (the vertical height direction of the substrate 1), and the second direction has a 90° angle with the first direction. Figure 6As shown, in actual setting, the punching knife 22 is placed in the through cavity 41 of the material placement mold 4 along the vertical height direction of the substrate 1, and the end of the punching knife 22 away from the base 21 extends to the first opening 411 of the through cavity 41; at this time, if the sprue 51 of the injection molded part 5 with a sprue can extend into the through cavity 41 of the material placement mold 4 from the above-mentioned first opening 411, then the blade 221 of the punching knife 22 is directly opposite to the sprue 51 of the injection molded part 5 with a sprue, so as to facilitate the subsequent punching out of the sprue 51 of the injection molded part 5 with a sprue under the drive of the driving component 3.

[0036] It should be noted that see Figure 3 and Figure 4 In order to ensure the smooth implementation of the sprue punching tooling and the reliability of the assembly of the punching knife 22, in actual setting, in the above-mentioned punching assembly 2, a mounting groove 211 and a first locking hole 212 arranged through the mounting groove 211 are provided in the base 21 of the punching assembly 2. The end of the punching knife 22 without the blade 221 is inserted into the mounting groove 211, and a second locking hole is arranged through the punching knife 22, so that the pin 23 passes through the first locking hole 212 and the second locking hole in sequence for locking and fixing.

[0037] At the same time, in the punching assembly 2 designed by the present invention, the above-mentioned base 21 is an "L"-shaped base 21, and when assembled, one end of the "L"-shaped base 21 loaded with the punch 22 extends into the through cavity 41 of the material placement mold 4, and the other end of the "L"-shaped base 21 is arranged outside the through cavity 41, and its size is larger than the cross-sectional size of the through cavity 41, so as to ensure that when the driving assembly 3 drives the punching assembly 2 to move along the first direction, the "L"-shaped base 21 can limit its own displacement distance and will not be completely immersed in the through cavity 41.

[0038] In addition, in order to further strengthen the restriction on the moving distance of the punching assembly 2, as Figure 4 and Figure 5 As shown, in the present embodiment, a limiting groove 213 is further provided on the base 21 of the punching assembly 2, and a through-type limiting hole 42 is further provided on the above-mentioned material placement mold 4, so that the limiting member 6 (for example, a pin) passes through the material placement mold 4 and is inserted into the limiting groove 213 of the base 21, thereby limiting the movement trajectory of the base 21.

[0039] Accordingly, in the present embodiment, the driving mechanism is designed to include a driving member 31 and a driving rod 32, and the driving member 31 is specifically selected as a cylinder, the output end of the driving member 31 is connected to one end of the driving rod 32, and the other end of the driving rod 32 is connected to the base 21 of the punching assembly 2 to drive the base 21 to move along the first direction; of course, in some other embodiments, a motor can also be selected as the driving member 31 according to actual usage requirements.

[0040] When the sprue punching tooling is actually applied, the injection molded part 5 with a sprue can be effectively matched and arranged on the material placement mold 4, and the sprue 51 of the injection molded part 5 with a sprue extends from the first opening 411 of the through cavity 41 into the through cavity 41 of the material placement mold 4. At this time, the blade 221 of the punch 22 arranged in the through cavity 41 is facing the sprue 51; through the driving action of the cylinder, the base 21 can be driven to move along the first direction, and the punch 22 can be driven to rush towards the sprue 51, thereby effectively cutting off the sprue 51 of the injection molded part 5 with a sprue.

[0041] It can be seen that the sprue punching tool designed by the utility model can effectively replace manual sprue cutting. The operator no longer needs to manually cut the sprue of the injection molded part. It is easy to operate and will not damage the injection molded part. It can greatly improve production efficiency, reduce the workload of operators, and improve production yield. It has good promotion prospects and application value.
