Description

Technical Field

[0001] The present application relates to the technical field of vertical injection molding machines, and in particular to an automatic switching mechanism between a single-color shooting station and a double-color shooting station. Background Art

[0002] With the continuous development of modern manufacturing, plastic products are increasingly used in various fields, and people's expectations for the appearance, function, and quality of plastic products are becoming increasingly higher. In the field of injection molding, multi-color injection molding technology has emerged and rapidly developed to meet diverse product demands. Multi-color injection molding can produce multiple colors on a single plastic product, greatly enriching the product's appearance and design. It can also achieve special functions by combining different colored materials. For example, on the casing of some electronic products, two-color injection molding creates different color areas to distinguish different function buttons or to provide dual functions of decoration and protection. In automotive interiors, multi-color injection molding is used to create aesthetically pleasing and ergonomic parts. Therefore, multi-color injection molding has broad application prospects in many industries, including electronics, automobiles, home appliances, and toys.

[0003] In existing vertical injection molding machines, there are various ways to perform multi-color injection molding. For example, "CN203680648U, Vertical two-color or multi-color turntable injection molding machine" discloses a two-color shooting table injection molding machine. Its working principle is to set up two shooting tables, and configure a turntable under the shooting table. The fixed angle rotation of the turntable is used to realize the switching of injection molding materials. However, this device cannot simultaneously perform the injection molding operation of two-color materials in the same mold. "CN218928434U, An injection system structure of a two-color machine suitable for a small center distance" also discloses a two-color shooting table injection molding machine. Although it can realize two-color injection molding, the position of the shooting table is fixed and cannot adapt to the switching operation between single and double colors. Therefore, in order to solve the above problems, the present application provides an automatic switching mechanism for a single-color shooting table and a two-color shooting table. Utility Model Content

[0004] In order to solve the problem that single-color and double-color switching and double-color synchronous injection molding cannot exist at the same time in the existing vertical injection molding machine, the present application provides an automatic switching mechanism for a single-color shooting table and a double-color shooting table.

[0005] The present application provides an automatic switching mechanism for a single-color shooting station and a double-color shooting station. The injection molding machine body includes a machine table and an upper mold on the machine table that is displaced along three axes of the hydraulic cylinder under the action of three hydraulic cylinders. A slide is provided above the upper mold. A shooting station group 1 and a shooting station group 2 are symmetrically provided along the center line above the slide. The shooting station group 1 and the shooting station group 2 operate independently of each other.

[0006] One side of the upper die is fixedly connected with a hydraulic cylinder 2 for driving the slide in the horizontal direction, thereby realizing switching between the shooting platform group 1 and the shooting platform group 2.

[0007] By setting a slide on the upper mold and driving the position of the slide through hydraulic cylinder 2, the positions of shooting platform group 1 and shooting platform group 2 can be switched, thereby realizing automatic switching between single-color and double-color shooting platforms and improving the applicability of the device.

[0008] Preferably, the upper die is provided with a slide groove to cooperate with the slide, and the top of the upper die is fixedly connected with guide rails for horizontally limiting the slide by bolts on both sides along the moving direction of the slide.

[0009] Preferably, the second hydraulic cylinder is located in the middle section of the side of the slide plate, and the second hydraulic cylinder is fixedly connected to the upper mold.

[0010] Preferably, both the shooting platform group 1 and the shooting platform group 2 are provided with a nozzle structure and an extrusion structure. A hydraulic cylinder 1 is provided on one side of the nozzle structure to drive it in the vertical direction. The nozzle structure and the extrusion structure are fixedly connected, and a barrel for loading materials is provided on the outside of the connection between the two.

[0011] Preferably, a guide rod is fixedly connected to the upper die, and the guide rod and the nozzle structure are slidably fitted.

[0012] Preferably, through slots are provided on the upper die corresponding to the first and second shooting platforms, and the through slots are used for adjusting the horizontal position of the nozzle structure.

[0013] Preferably, the hydraulic cylinder three is located at the bottom of the machine platform, the output end of the hydraulic cylinder three is fixedly connected to four Corinthian columns through a connecting frame, the hydraulic cylinder three drives the Corinthian columns to perform axial displacement, and the top end of the Corinthian columns is fixedly connected to the upper mold.

[0014] In summary, this application has the following beneficial technical effects:

[0015] By arranging a slide groove on the upper mold, a slide plate sliding in the horizontal direction under the limit of the guide rail is arranged in the slide groove, and a hydraulic cylinder 2 is arranged on one side of the slide plate, and the hydraulic cylinder 2 is used to drive the position of the slide plate, thereby realizing the position adjustment of the shooting platform group 1 and the shooting platform group 2. Moreover, since the shooting platform group 1 and the shooting platform group 2 operate independently of each other, compared with the existing technology, it can realize single-color discharging and double-color discharging, and can also realize the position switching of the shooting platform group during the processing process, thereby improving the scope of application of the device.

[0020] The following is combined with Figure 1 - Figure 3 This application is described in further detail.

[0021] Example 1:

[0022] An automatic switching mechanism for a single-color shooting table and a double-color shooting table, referring to Figure 1 - Figure 3 The injection molding machine body includes a machine table 9 and an upper mold 7 on the machine table 9, which is displaced axially along the hydraulic cylinder three 10 under the action of the hydraulic cylinder three 10. A guide rod 6 is fixedly connected to the upper mold 7, and the guide rod 6 and the nozzle structure 3 are slidably fitted. A ring is provided on the nozzle structure 3, and the ring and the guide rod 6 are slidably fitted to ensure the accuracy of the vertical movement of the nozzle structure 3. At the same time, it can reduce the force of the hydraulic cylinder one in the non-axial direction, thereby reducing the risk of damage and oil leakage of the hydraulic cylinder one.

[0023] Hydraulic cylinder three 10 is located at the bottom of the machine platform 9. The output end of hydraulic cylinder three 10 is fixedly connected to four Corinthian columns 13 through a connecting frame. Hydraulic cylinder three 10 drives the Corinthian columns 13 to perform axial displacement. The top end of the Corinthian columns 13 is fixedly connected to the upper mold 7. The connection between the upper mold 7 and hydraulic cylinder three 10 is realized through the Corinthian columns 13, so that the upper mold 7 is driven to change its vertical position during the extension and retraction process of hydraulic cylinder three 10, thereby realizing the mold opening and closing effects.

[0024] A slide plate 11 is provided above the upper die 7, and a shooting platform group 1 1 and a shooting platform group 2 2 are symmetrically provided above the slide plate 11 along the center line. The shooting platform group 1 1 and the shooting platform group 2 2 operate independently of each other. The slide plate 11 is fixedly connected to the bottom ends of the shooting platform group 1 1 and the shooting platform group 2 2, so that when the slide plate 11 is displaced, the shooting platform group 1 1 and the shooting platform group 2 2 move synchronously therewith; a through groove 72 is opened on the upper die 7 corresponding to the shooting platform 1 and the shooting platform 2, and the through groove 72 is used for adjusting the horizontal position of the nozzle structure 3.

[0025] On one side of the upper mold 7, a hydraulic cylinder 2 8 for driving the slide 11 in the horizontal direction is fixedly connected by bolts. The hydraulic cylinder 2 8 is located in the middle of the side of the slide 11, and the hydraulic cylinder 2 8 and the upper mold 7 are fixedly connected. The hydraulic cylinder 2 8 realizes the switching between the shooting platform group 1 and the shooting platform group 2 2. The upper mold 7 is provided with a slide groove 71 to cooperate with the slide 11, and the top of the upper mold 7 is fixedly connected with guide rails 12 for horizontally limiting the slide 11 on both sides of the moving direction of the slide 11 by bolts. The guide rails 12 adopt an L-shaped structure, which is covered on both sides of the outer side of the slide 11. In the process of the hydraulic cylinder 2 8 transmitting the slide 11 along its axial direction, the position of the slide 11 is kept relatively stable, and the non-axial force on the output shaft of the hydraulic cylinder 2 8 is reduced, thereby improving the durability of the hydraulic cylinder 2 8. At the same time, the guide rails 12 ensure the horizontal stability of the slide 11, and avoid the stability of the slide 11 being reduced due to the influence of the shooting platform group 1 and the shooting platform group 2.

[0026] Both the shooting platform group 1 and the shooting platform group 2 2 are provided with a nozzle structure 3 and an extrusion structure 4. A hydraulic cylinder 1 is provided on one side of the nozzle structure 3 to drive it in the vertical direction. The nozzle structure 3 and the extrusion structure 4 are fixedly connected, and a barrel 5 for loading is provided on the outside of the connection between the two. During the operation of the shooting platform, the heating system provided on the nozzle structure 3 first melts the material input from the barrel 5, and the melted material is transported forward by the threaded rod provided by the extrusion structure 4. During the mold closing process, the hydraulic cylinder 3 10 extends, and the upper mold 7 moves downward to achieve the fitting between the molds. Then the hydraulic cylinder 1 contracts, and the nozzle structure 3 and the injection port of the upper mold 7 are tightly fitted. The hydraulic transmission structure on the extrusion structure 4 realizes the axial displacement of the entire extrusion structure 4, and the molten material in the nozzle structure 3 is extruded. The material enters the mold flow channel and solidifies and forms, thus completing the injection molding operation.

[0027] The presence of the second hydraulic cylinder 8 enables the device to select the material to be injected. When performing single-color injection molding, the position of the slide 11 can be adjusted by the second hydraulic cylinder 8, thereby achieving the correspondence between the single-material shooting platform group 1 or the shooting platform group 2 and the mold injection port. When performing two-color injection molding, the position of the slide 11 can also be adjusted by the second hydraulic cylinder 8, so that the shooting platform group 1 and the shooting platform group 2 of the two-color material can independently inject the mold injection port, thereby improving the applicability of the device.

[0028] The above describes an exemplary implementation of the automatic switching mechanism for a single-color shooting table and a two-color shooting table provided by the present disclosure with reference to preferred embodiments. However, it will be understood by those skilled in the art that, without departing from the concept of the present disclosure, various variations and modifications can be made to the above-mentioned specific embodiments, and various combinations of the various technical features and structures proposed in the present disclosure can be made without exceeding the scope of protection of the present disclosure, which is determined by the appended claims.
