Description

Technical Field

[0001] This invention relates to an injection mold with automatic in-mold metal strip feeding, and more particularly to a bending, injection, and punching composite mold with automatic in-mold metal strip feeding. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] Currently, injection molds with automatic in-mold metal strip feeding can only continuously complete the injection molding of the product object on the metal strip. The bending and punching of the product object on the metal strip must be completed after demolding and unloading in the injection mold and then transferred to the bending or punching machine, which will seriously affect the production efficiency.

[0004] Therefore, this invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a bending, injection molding, and stamping composite mold with automatic in-mold metal strip feeding that can improve product production efficiency.

[0006] To achieve the above objectives, the present invention provides a bending, injection molding, and blanking composite mold with automatic in-mold metal strip feeding. The mold structure includes the following components:

[0007] A bending forming component for bending and forming products on a metal strip, comprising:

[0008] The mold core 1, the needle bar 1 with one end facing the cavity of the mold core 1, and the protrusion 1 that cooperates with the other end of the needle bar 1 and drives the needle bar 1 to bend the product in the cavity of the mold core 1;

[0009] Mold core two is used for injection molding of products on metal strips;

[0010] A stamping forming component for stamping products from metal strip, comprising:

[0011] The mold core three, the needle bar two with one end facing the cavity of the mold core three, and the protrusion two that cooperates with the other end of the needle bar two and drives the needle bar two to punch the product in the cavity of the mold core three;

[0012] Transmission mechanism one is used to drive the moving mold component to continuously reciprocate;

[0013] And, transmission mechanism two, used to drive the moving mold component to continuously reciprocate the protrusion two;

[0014] Among them, the die core one and die core two of the bending forming component and the die core three of the punching forming component are distributed on the feeding path of the metal strip.

[0015] The bending, injection molding, and stamping composite mold with automatic in-mold metal strip feeding provided above can continuously achieve bending, injection molding, and stamping of product objects through automatic in-mold metal strip feeding. This eliminates the time spent on transferring and transporting product objects between the three stations of bending, injection molding, and stamping, thereby improving product production efficiency.

[0016] The aforementioned bending injection stamping composite mold with automatic in-mold metal strip feeding, wherein the specific structure of the needle bar is preferably selected to include:

[0017] A rod body, wherein a hinge seat portion is formed on one side of the rod body facing the cavity of the mold core;

[0018] magnet;

[0019] And, torsion spring one;

[0020] The magnet is hinged to the hinge seat of the rod via a hinge shaft; a torsion spring is bushed on the hinge shaft, with one end fixed to the hinge shaft and the other end fixed to the magnet.

[0021] During the bending and forming process of the product on a pair of metal strips on the needle bar, the magnet always magnetically attracts the product on the metal strip, and the torsion spring is compressed simultaneously to generate a restoring force on the magnet.

[0022] In the above-mentioned preferred technical solution, during the bending and forming process of the product on a pair of metal strips on the needle bar, the bending part of the product is always attracted by magnetic force, so as to simulate the mechanical fingers holding the bending part of the product to achieve bending and forming, thereby improving the accuracy of product bending and forming.

[0023] The aforementioned bending injection stamping composite mold with automatic in-mold metal strip feeding, wherein the specific structures of the transmission mechanism one and the transmission mechanism two are preferably selected to include:

[0024] The connecting rod consists of a rod part one, a rod part two, and a hinge joint part two at the transition between the rod part one and the rod part two; wherein, the hinge joint part two of the connecting rod is hinged to the hinge seat part two formed on the fixed mold frame through the hinge shaft two, and the rod part one extends toward the moving mold base plate.

[0025] Torsion spring 2 is bushed on hinge shaft 2, with one end fixed to hinge joint 2 and the other end fixed to hinge seat 2;

[0026] The top plate is located on one side of the second part of the connecting rod, and the two are fixed together;

[0027] And a push rod, which is located on one side of the top plate, wherein one end of the push rod forms a hinge joint portion three and is hinged to a hinge seat portion three formed on the corresponding side of the top plate;

[0028] In the mold closing process of the moving mold component, the moving mold base plate applies a force to the connecting rod, and the top plate drives the push rod to travel a set stroke, while the torsion spring is passively compressed to generate a reset force on the push rod.

[0029] In this embodiment, the other end of the push rod of transmission mechanism one extends toward protrusion one and is fixed thereto; the other end of the push rod of transmission mechanism two extends toward protrusion two and is also fixed thereto.

[0030] The above-mentioned preferred technical solution provides a bending, injection molding, and stamping composite mold with automatic in-mold metal strip feeding. During the mold closing process of the moving mold component, the moving mold base plate applies force to the connecting rod, making reasonable use of the mold closing force of the composite mold. This eliminates the need to add separate power sources (motors, cylinders, etc.) to the bending forming component and the stamping forming component, thereby reducing the overall manufacturing cost of the composite mold and improving the synchronicity of the three stations of bending forming, injection molding, and stamping forming in the composite mold, as well as better coordinating the automatic in-mold metal strip feeding.

[0031] Compared with the prior art, the bending injection stamping composite mold with automatic in-mold metal strip feeding obtained by the present invention has the following technical advantages and features:

[0032] 1.

Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0047] like Figures 1-9As shown, as one embodiment of the present invention, this embodiment provides a bending injection stamping composite mold with automatic in-mold metal strip feeding. The mold structure includes the following components, specifically:

[0048] A bending forming component for bending products on a metal strip, comprising:

[0049] A mold core 1 consists of a moving mold core 1 and a fixed mold core 1. After the mold is closed, the two together form a cavity for bending and forming the product on the metal strip. A needle bar 2 has one end facing the cavity of the mold core 1, and a protrusion 3 that cooperates with the other end of the needle bar 2 and drives the needle bar 2 to bend the product in the cavity of the mold core 1.

[0050] Both mold cores 4 are used for injection molding of products on metal strips. Each mold core 4 consists of only one fixed mold core 2 and corresponds to the runner 15 of the composite mold. The fixed mold core 2 forms the cavity for injection molding of products on metal strips.

[0051] A blanking forming component for blanking products from metal strip, comprising:

[0052] A mold core 3 5 consists of a moving mold core 3 and a fixed mold core 3. After the mold is closed, the two together form a cavity for punching and forming the product on the metal strip. There are four pin bars 2 6 with one end facing the cavity of the mold core 3 5. The four pin bars 2 6 are divided into two groups, and there is a pair of protrusions 2 7 that correspond one-to-one with the two groups of pin bars 2 6. Each protrusion 2 7 cooperates with the other end of the two pin bars 2 6 in its corresponding group and drives the two pin bars 2 6 to punch the product in the cavity of the mold core 3 5.

[0053] A transmission mechanism is used to drive the protrusion 3 of the moving mold component to reciprocate continuously;

[0054] And a transmission mechanism 2, used to drive the moving mold component to continuously reciprocate the protrusion 2 7;

[0055] Among them, such as Figure 3 As shown, the die cores 1 and 4 of the bending forming component and the die core 5 of the punching forming component are distributed sequentially on the feeding path of the metal strip.

[0056] The bending, injection molding, and stamping composite mold with automatic in-mold metal strip feeding provided above can continuously achieve bending, injection molding, and stamping of product objects through automatic in-mold metal strip feeding. This eliminates the time spent on transferring and transporting product objects between the three stations of bending, injection molding, and stamping, thereby improving product production efficiency.

[0057] The specific structure of the transmission mechanism one described in this embodiment includes:

[0058] Each pair of connecting rods 8 consists of a rod part 8-1, a rod part 8-2, and a hinge joint part 8-3 at the transition between rod part 8-1 and rod part 8-2, forming an included angle α between rod part 8-1 and rod part 8-2 (the included angle α is 120° in the figure in the specification drawing); wherein, the hinge joint part 8-3 of each connecting rod 8 is hinged to a hinge seat part 10-1 formed on the fixed mold frame 10 through a hinge shaft 9, and rod part 8-1 extends toward the moving mold base plate 11;

[0059] A pair of torsion springs 12 are respectively bushed on a hinge shaft 9, with one end fixed to its corresponding hinge shaft 9 and the other end fixed to its corresponding hinge seat 10-1.

[0060] A top plate 13 is located on the same side of the second 8-2 of a pair of connecting rods 8 and is fixed to the second 8-2 of the pair of connecting rods 8;

[0061] And a push rod 14 located on one side of the top plate 13, wherein one end of the push rod 14 forms a hinge joint portion three 14-1 and is hinged to a hinge seat portion three 13-1 formed on the corresponding side of the top plate 13.

[0062] In the mold closing process of the moving mold component, the moving mold base plate 11 applies a force to a pair of connecting rods 8, and simultaneously a top plate 13 drives a push rod 14 to travel a set stroke, and a pair of torsion springs 12 are passively compressed to generate a reset force on the push rod 14.

[0063] The specific structure of the transmission mechanism 2 described in this embodiment is roughly the same as that of the transmission mechanism 1 described above. However, the transmission mechanism 2 includes a pair of push rods 14, which are located on one side of the top plate 13. Each push rod 14 forms a hinge joint part 3 14-1 on one side end and is hinged to a hinge seat part 3 13-1 formed on the corresponding side of the top plate 13.

[0064] In this embodiment, the other end of one push rod 14 of the transmission mechanism one extends toward a protrusion 3 and is fixed thereto; the other ends of the other two push rods 14 of the transmission mechanism two extend toward a pair of protrusions 2, corresponding one to one, and each push rod 14 is fixed to its corresponding protrusion 2. In this embodiment, the push rod 14 and the protrusion are designed as an integral structure, so the structure of both has good stability. During the mold closing process of the moving mold component, the force is applied to the connecting rod 8 through the moving mold base plate 11, which makes reasonable use of the mold closing force of the composite mold, without the need to add a separate power source (motor, cylinder, etc.) to the bending forming component and the punching forming component, thereby reducing the overall production cost of the composite mold and improving the synchronicity of the three stations of bending forming, injection forming and punching forming in the composite mold, and better coordinating the automatic feeding of the metal strip in the mold.

[0065] As a second embodiment of the present invention, the bending, injection molding, and blanking composite mold with automatic in-mold metal strip feeding provided in this embodiment has a generally consistent structure with the first embodiment described above, such as... Figure 10 As shown, however, the specific structure of the needle bar 2 in this embodiment includes: a rod body 2-1, wherein a hinge seat 2-2 is formed on one side of the rod body 2-1 facing the cavity of the mold core 1; a magnet 2-3; and a torsion spring 2-4;

[0066] Among them, a magnet 2-3 is hinged to the hinge seat 2-2 of the rod 2-1 via a hinge shaft 2-5; a torsion spring 2-4 is bushed on the hinge shaft 2-5, with one end fixed to the hinge shaft 2-5 and the other end fixed to the magnet 2-3.

[0067] During the bending and forming process of the product on the metal strip by the needle bar 2-2, the magnet 2-3 always magnetically attracts the product on the metal strip, and the torsion spring 2-4 is compressed to generate a restoring force on the magnet 2-3.

[0068] In this embodiment, a bending injection molding and punching composite mold with automatic in-mold metal strip feeding is described. In its structure, the needle bar 2 can continuously attract the bent part of the product through magnetic force during the bending process of the product on the metal strip, so as to simulate the mechanical fingers holding the bent part of the product to achieve bending and forming, thereby improving the accuracy of product bending and forming.

[0069] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
