Description

Technical Field

[0001] This utility model relates to the field of positioning pin technology, and in particular to an inner and outer plug assembly for a rubber mold. Background Technology

[0002] The inner and outer plugs of a mold usually refer to the vent plugs and locating pins in the mold. The function of the locating pin in the mold is to ensure that the various parts of the mold can be accurately aligned when the mold is closed, simplifying the installation process. The locating pin is usually installed in the key parts of the mold, such as between the mold plates or between the mold and the injection molding machine, to ensure that the mold remains stable during the injection process and avoid quality problems caused by positional deviations.

[0003] In existing locating pins, hammering is typically used to drive them into the mold, but this method can easily damage the tip of the pin. In addition, existing locating pins are inconvenient to disassemble. Therefore, we propose an inner and outer plug assembly for a rubber mold to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an inner and outer plug assembly for a rubber mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An inner and outer plug assembly for a rubber mold includes a locating pin and an auxiliary tool. The upper surface of the locating pin has a screw hole, and the top of the locating pin has a symmetrical insertion hole. A protective component is slidably connected inside the two insertion holes. The auxiliary tool includes a threaded rod that is adapted to the screw hole. A fixing block is fixedly connected to the top of the threaded rod, and a symmetrical handle is fixedly connected to the outer surface of the fixing block.

[0007] In a further embodiment, the bottom end of the locating pin is tapered.

[0008] In a further embodiment, the outer surfaces of both handles are threaded, and a ball is threadedly connected to the outer surfaces of both handles.

[0009] In a further embodiment, the protective component includes a protective plate, the bottom surface of which is fixedly connected to symmetrical insert rods, both of which are located inside the insertion hole.

[0010] In a further embodiment, a buffer pad is movably connected to the bottom surface of the protective plate. The buffer pad has symmetrical movable holes inside. Both of the insert rods pass through the movable holes and extend to the bottom surface of the buffer pad. The buffer pad is movably connected to the top of the positioning pin.

[0011] In a further embodiment, the protective plate is made of an alloy, and the diameter of the protective plate is larger than that of the locating pin.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device features a protective component at the top of the positioning pin. The protective plate is made of alloy material and has a diameter larger than the positioning pin. During installation, the protective plate can be struck with a hammer instead of directly striking the top of the positioning pin, preventing damage to the pin from external impact and extending its service life. Using an auxiliary tool consisting of a threaded rod, a fixing block, and a handle, rotating the handle drives the threaded rod into the threaded hole. By holding the handle and lifting the positioning pin upwards, the positioning pin can be easily removed from the mold. The operation is simple and convenient, improving work efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4In this utility model, an inner and outer plug assembly for a rubber mold includes a positioning pin 1 and an auxiliary tool 2. The upper surface of the positioning pin 1 is provided with a screw hole 6, and the top of the positioning pin 1 is provided with a symmetrical insertion hole 5. The two insertion holes 5 are slidably connected to a protective component 3. The auxiliary tool 2 includes a threaded rod 201, which is adapted to the screw hole 6. The top of the threaded rod 201 is fixedly connected to a fixing block 202, and the outer surface of the fixing block 202 is fixedly connected to a symmetrical handle 203. By providing the protective component 3, the top of the positioning pin 1 can be prevented from being damaged by external impact, thus extending its service life. By providing the auxiliary tool 2, the positioning pin 1 can be easily removed from the mold, making the operation simple and convenient and improving work efficiency.

[0021] The bottom end of the positioning pin 1 is tapered, which makes it easier to insert the positioning pin 1 into the mold, improving the accuracy and convenience of installation.

[0022] Both handles 203 have threads on their outer surfaces, and both handles 203 have balls 7 threadedly connected to their outer surfaces. When in use, the balls 7 can increase the friction between the hand and the handles 203, making it easier to grip.

[0023] The protective component 3 includes a protective plate 301. The bottom surface of the protective plate 301 is fixedly connected with symmetrical insert rods 302. Both insert rods 302 are located inside the insertion hole 5. The protective plate 301 can be easily disassembled and installed through the sliding connection between the insert rods 302 and the insertion hole 5.

[0024] The bottom surface of the protective plate 301 is movably connected to a buffer pad 4. The buffer pad 4 has symmetrical movable holes 8 inside. Both insert rods 302 pass through the movable holes 8 and extend to the bottom surface of the buffer pad 4. The buffer pad 4 is movably connected to the top of the positioning pin 1. When the protective plate 301 is struck, the buffer pad 4 can further buffer the impact force and reduce vibration damage to the positioning pin 1.

[0025] The protective plate 301 is made of alloy and its diameter is larger than that of the positioning pin 1. Because the protective plate 301 is made of alloy, it has high strength and wear resistance, and can withstand the impact of hammering, preventing itself from being deformed or damaged due to hammering. Because the diameter of the protective plate 301 is larger than that of the positioning pin 1, it can form a larger impact contact surface and evenly transmit the impact force.

[0026] The working principle of this utility model is as follows:

[0027] When installing the positioning pin 1, align the conical bottom end of the positioning pin 1 with the positioning hole of the mold, so that the positioning pin 1 is initially inserted into the mold. Then, insert the insert rod 302 of the protective component 3 into the insert hole 5 at the top of the positioning pin 1, so that the protective plate 301 is above the top of the positioning pin 1 and the buffer pad 4 is in contact with the top of the positioning pin 1. Then, use a hammer to strike the protective plate 301, and transmit the impact force to the positioning pin 1 through the protective plate 301 and the buffer pad 4, so that the positioning pin 1 is gradually inserted into the mold to complete the installation. When removing the positioning pin 1, align the threaded rod 201 with the threaded hole 6 on the positioning pin 1, rotate the handle 203 to screw the threaded rod 201 into the threaded hole 6, and then hold the handle 203 and lift the positioning pin 1 upward to remove the positioning pin 1 from the mold.
