Description

Technical Field

[0001] This invention belongs to the field of heating equipment technology, specifically relating to a heating device for embedding pins in injection molds. Background Technology

[0002] Heating equipment is generally a device composed of heating elements and accessories. A glass fiber reinforced refractory fiber layer is wound around a multi-strand resistance wire, and a metal wire reinforced refractory fiber layer is woven outside the refractory fiber layer. This tightly bonded double-layer covering, distributed along the entire length of the resistance wire, together with the central resistance wire, forms a single, directly heating unit that can be bent as needed and can make close contact with the object being heated. The heating unit is repeatedly wound and rolled into a strip shape according to the shape and size of the object being heated. Then, multiple parallel units are horizontally woven together with metal wire to form a braided high-temperature electric heater that can be directly wrapped around the object being heated for immediate use.

[0003] In certain mold production processes, matching screws need to be placed in heating equipment and heated to a certain temperature before being inserted into the mold core for injection molding. However, existing heating equipment results in uneven heating of the screw surface, which can easily cause local overheating and lead to low heating efficiency. Furthermore, the heated screws are inconvenient to handle due to their high temperature, posing a risk of burns. In addition, improper placement of the screws during manual handling can damage the mold and hinder production. Summary of the Invention

[0004] In view of the problems mentioned in the background art above, the object of the present invention is to provide a heating device for embedding pins in injection molds.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A heating device for embedding screws in injection molds includes a heating box with an installation cavity and a heating cavity. A servo motor is mounted on the top of the heating box, and the power output end of the servo motor is connected to a transmission mechanism. The transmission mechanism is installed in the installation cavity and connected to a screw clamping seat. A heating tube with a spiral structure is installed in the heating cavity at the corresponding screw clamping seat. A limiting slide is installed at the bottom of the heating box, and a limiting mechanism is installed inside the limiting slide. A T-shaped screw box is slidably connected to the limiting slide, and a material removal port is provided at the bottom of the T-shaped screw box. Support frames are installed on both sides of the top of the heating box, and electric slide rails are installed on the support frames. A robotic arm is connected to the electric slide rails, and a screw suction cup is connected to the robotic arm.

[0007] Furthermore, the servo motor is equipped with a protective outer shell. This structural design provides protection for the servo motor.

[0008] Further specifying, the transmission mechanism includes a first transmission wheel connected to a transmission belt, a second transmission wheel connected to the other side of the transmission belt, a belt connected to the second transmission wheel, and four sets of pulleys connected to the belt. These four sets of pulleys are arranged in a square, evenly spaced arrangement within the mounting cavity. This structural design ensures consistent rotational motion.

[0009] Furthermore, the pulley has a through-hole groove at its center, which is coaxial with the center of the screw clamp. A plug is installed inside the through-hole groove. This structural design facilitates the limiting and fixing effect on the screw.

[0010] Furthermore, the pulley is configured in an I-shape, the belt is installed in the central groove of the pulley, and bearings are connected to both sides of the pulley, with the bearings installed inside the heating chamber. This structural design facilitates the rotational movement of the pulley.

[0011] Furthermore, heating tube mounting brackets are installed on both sides of the heating tube, and these brackets are fixedly installed inside the heating chamber. This structural design facilitates the fixed installation of the heating tube.

[0012] Furthermore, an L-shaped locking plate is fixedly installed on one side of the top of the heating box. The L-shaped locking plate has several evenly arranged threaded holes, and a screw is connected to each threaded hole. A torsion plate is connected to one side of the screw, and a compression pad is connected to the other side of the screw. This structural design facilitates the installation and fixation of the heating box.

[0013] Further specifying, the limiting mechanism includes a spring installed within a limiting slide, the free end of the spring connected to a bead holder, the bead holder slidably mounted on the limiting slide, a bead slidably mounted on the top of the bead holder, and bead grooves on both sides of the bottom of the T-shaped screw box corresponding to the bead, with the top of the bead mounted within the bead grooves. This structural design effectively limits the installation of the T-shaped screw box.

[0014] Furthermore, the screw clamp is secured to the pulley by screws, and the screw clamp is rotatably mounted inside the heating chamber. This structural design facilitates the locking, installation, and rotation of the screw clamp.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention sets up a transmission mechanism, a screw clamping seat, and a heating tube. The transmission mechanism is driven by a servo motor, which enables the transmission mechanism to synchronously drive the screw clamping seat, which holds the screw, to rotate. At the same time, the screw is heated evenly in the heating tube, which prevents local overheating and improves heating efficiency.

[0017] 2. This invention utilizes a robotic arm and a screw suction cup. Through the coordinated use of the robotic arm and the screw suction cup, the robotic arm drives the screw suction cup to grasp the screw and move it into the heating chamber for heating. After heating, the robotic arm again drives the screw suction cup to move the screw to the corresponding position in the mold for production. The robotic arm avoids the risk of workers being burned by the high-temperature screws, and also avoids the risk of improper placement of screws when operated manually. Controlling the robotic arm to perform single, repetitive actions has higher precision and efficiency than manual operation, effectively solving the problems of low efficiency and inconvenience of manual operation. The risk of mold damage can be minimized, making it convenient for production use. Attached Figure Description

[0026] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-5 As shown, the present invention discloses a heating device for embedding screws in injection molds. The heating chamber 1 has an installation cavity 2 and a heating cavity 3. A servo motor 4 is installed on the top of the heating chamber 1. The power output end of the servo motor 4 is connected to a transmission mechanism 5. The transmission mechanism 5 is installed in the installation cavity 2 and connected to a screw clamping seat 6. A heating tube 7 is installed in the heating cavity 3 at the corresponding screw clamping seat 6. The heating tube 7 has a spiral structure.

[0028] In this embodiment, during use, the T-shaped screw box 10 filled with screws is inserted into the limiting slide block 8. Under the action of the limiting mechanism 9, the T-shaped screw box 10 is limited and fixed. Then, by controlling the robotic arm 14, the robotic arm 14 drives the screw suction cup 15 to take out the screws from the feeding port 11 of the T-shaped screw box 10, and inserts the screws into the screw clamping seat 6 through the through hole groove 22 in the pulley 21. The screw clamping seat 6 fixes the screws, so that the heated end of the screw enters the heating chamber 3. After all four sets of screw clamping seats 6 have clamped the screws, the servo motor 4 and the heating tube 7 are started by controlling the servo motor 4 to drive the transmission. When the drive mechanism 5 is in motion, the first drive wheel 17 drives the drive belt 18, the drive belt 18 drives the second drive wheel 19, the second drive wheel 19 drives the belt 20, and the belt 20 simultaneously drives four sets of pulleys 21 to move synchronously. This causes the four sets of pulleys 21 to drive their respective connected screw clamps 6, and the screw clamps 6 to rotate the screw inside the heating tube 7. The heating tube 7 heats the rotating screw, making the heating area of ​​the screw uniform and increasing the heating speed. After heating is completed, the robotic arm 14 is controlled again to place the heated screw into the mold, and then the mold is used for production.

[0029] Preferably, a protective housing 16 is installed on the outside of the servo motor 4. This structural design provides protection for the servo motor 4. In practice, other structural shapes of the protective housing 16 can also be considered depending on the specific circumstances.

These four sets of pulleys 21 are arranged in a square and evenly within the mounting cavity 2. This structural design ensures consistent rotational motion. In practice, other structural shapes of the transmission mechanism 5 can also be considered depending on the specific circumstances.

[0031] Preferably, the pulley 21 has a through-hole groove 22 at its center, which is coaxial with the center of the screw clamp 6. A plug is installed inside the through-hole groove 22.

This structural design facilitates the fixed installation of the heating tube 7. In practice, other installation structure shapes for the heating tube 7 can also be considered depending on the specific circumstances.

[0034] Preferably, an L-shaped locking plate 24 is fixedly installed on one side of the top of the heating box 1. The L-shaped locking plate 24 has several evenly arranged threaded holes, and screws 25 are connected to the threaded holes. A torsion plate 26 is connected to one side of the screw 25, and a compression pad 27 is connected to the other side of the screw 25.

In practice, other installation structure shapes for the heating box 1 can also be considered depending on the specific circumstances.

[0035] The preferred limiting mechanism 9 includes a spring 28 installed within the limiting slide 8. The free end of the spring 28 is connected to a bead holder 29, which is slidably mounted on the limiting slide 8. A bead 30 is slidably mounted on the top of the bead holder 29. The bottom sides of the T-shaped screw box 10 have bead grooves corresponding to the bead 30, with the top of the bead 30 installed within these grooves. This structural design effectively limits the installation of the T-shaped screw box 10. In practice, other structural shapes of the limiting mechanism 9 can also be considered depending on the specific circumstances.

[0036] The preferred screw clamp 6 is mounted on the pulley 21 by screws, and is rotatably mounted inside the heating chamber 1. This structural design facilitates the locking, mounting, and rotation of the screw clamp 6. In practice, other connection and mounting structures for the screw clamp 6 can also be considered depending on the specific circumstances.
