Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, specifically to an injection compression device with a defoaming structure. Background Technology
[0002] Injection molding is a method of industrial product manufacturing, typically using rubber or plastic injection molding. It can be further divided into injection molding compression molding and die casting. An injection molding machine is the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. Injection molding is achieved through an injection molding machine and a mold. An injection compression molding device is a piece of equipment used in the injection molding process that combines injection and compression technologies to improve the quality and performance of plastic products. It consists of an injection system and a compression system. During injection compression molding, the mold cavity space can be automatically adjusted according to different requirements. Initially, the mold guide is partially closed, and the cavity space expands to twice the finished wall thickness of the part. Then, depending on the operating method, the size of the cavity space is controlled during or after material injection to maintain appropriate polymer pressure and compensate for material shrinkage. However, existing injection compression molding devices do not vibrate the injection mold during use, failing to expel gas from the material, which can easily lead to air bubbles inside the device and affect product inspection. Utility Model Content
[0003] The purpose of this invention is to provide an injection compression device with a defoaming structure to solve the problem mentioned in the background art that if the injection mold is not vibrated, the gas in the material cannot be discharged, which easily causes bubbles to form inside the device and affects product inspection.
[0004] To achieve the above objectives, the present invention provides the following technical solution: an injection molding compression device with a defoaming structure, comprising a base, wherein the base is configured as an open square shell structure, and a lower mold is embedded inside the base;
[0005] The base has symmetrically fixed sliding rods on its surface, and the ends of the sliding rods are connected to a top plate. The base has a moving mechanism, which includes: a cylinder installed at the bottom of the top plate, and an upper mold connected to the output shaft of the cylinder; mounting blocks symmetrically installed on the surface of the upper mold, and the mounting blocks are sleeved on the outside of the sliding rods; connecting rods symmetrically connected to the surface of the upper mold, and a magnetic block one connected to the bottom of the connecting rods; baffles symmetrically embedded inside the lower mold, and a magnetic block two connected to the end of the baffles penetrating the surface of the lower mold; a spring one connected between the base and the lower mold; pipes symmetrically embedded on the surface of the lower mold; and a spring two connected between the lower mold and the magnetic block two.
[0006] Preferably, the base and the lower mold are slidably connected, and the ends of the upper mold and the lower mold are magnetically connected, with the sliding rods symmetrically arranged on both sides of the lower mold.
[0007] Using the above technical solution, the cylinder drives the lower mold to move, causing the lower mold to slide up and down inside the base.
[0008] Preferably, the mounting block and the slide rod are slidably connected, and the upper mold and the slide rod are slidably connected.
[0009] Using the above technical solution, the cylinder pushes the upper mold to move, causing the upper mold to move the mounting block on the surface of the slide rod.
[0010] Preferably, the connecting rod is configured as an L-shaped structure, and the connecting rod is located on the outside of the base, and the base and the connecting rod are slidably connected.
[0011] Using the above technical solution, the connecting rod moves downward, causing the connecting rod to drive the magnet to move downward as well.
[0012] Preferably, the end of the baffle is positioned to fit against the bottom of the lower mold, and the lower mold and the baffle are slidably connected.
[0013] Using the above technical solution, the baffle can support the bottom of the lower mold and fix the position of the lower mold.
[0014] Preferably, the baffle and the base are slidably connected, the positions of the first magnetic block and the second magnetic block are correspondingly set, and the first magnetic block and the second magnetic block have the same magnetic pole.
[0015] Using the above technical solution, when magnet one approaches magnet two, due to the repulsive force, magnet two causes the baffle to slide outward inside the base.
[0016] Preferably, the pipe is configured as an arc-shaped structure, and the end of the pipe extends through the outer side of the base.
[0017] By using the above technical solution, condensate or hot air can flow inside the pipe, which can be used to form the mold.
[0018] Compared with the prior art, the beneficial effects of this utility model are: the injection compression device equipped with a defoaming structure:
[0019] 1. A moving mechanism is set up to facilitate defoaming. The cylinder pushes the upper mold to move downward, so that the upper mold and the lower mold fit together. When magnet one moves to the surface of magnet two, magnet one pushes magnet two to move outward. At this time, the baffle loses contact with the lower mold, so that the cylinder pushes the upper mold and the lower mold to move at the same time, vibrating the inside, which can expel the internal air bubbles and improve the practicality of the device.
[0020] 2. Pipes are installed to allow hot air to move inside. Heat is then transferred to the surface of the lower mold through the base, heating the model inside the lower mold and improving the efficiency of the device. At the same time, condensate enters the pipes to cool the lower mold and the model inside. Attached Figure Description

[0030] 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.
[0031] Please see Figure 1-5 This utility model provides a technical solution: an injection compression device with a defoaming structure, including a base 10, a lower mold 20, a slide bar 30, a top plate 301, a cylinder 40, an upper mold 401, a mounting block 402, a connecting rod 403, a first magnetic block 404, a second magnetic block 405, a baffle 406, a first spring 407, a second spring 408, and a pipe 50;
[0032] This injection molding compression device facilitates defoaming, improving the device's practicality. The specific implementation method is as follows:
[0033] The base 10 is an open square shell structure, and a lower mold 20 is embedded inside the base 10. Slide rods 30 are symmetrically fixedly connected to the surface of the base 10, and a top plate 301 is connected to the end of each slide rod 30. A moving mechanism is provided on the surface of the base 10, including: a cylinder 40 mounted at the bottom of the top plate 301, with the output shaft of the cylinder 40 connected to an upper mold 401; mounting blocks 402 symmetrically mounted on the surface of the upper mold 401, with the mounting blocks 402 sleeved on the outside of the slide rods 30; connecting rods 403 symmetrically connected to the surface of the upper mold 401, with a first magnet 404 connected to the bottom of the connecting rods 403; baffles 406 symmetrically embedded inside the lower mold 20, with the end of the baffles 406 penetrating the surface of the lower mold 20 and connected to a second magnet 405; a spring 407 connecting the base 10 and the lower mold 20; and pipes 50 symmetrically embedded on the surface of the lower mold 20. A spring 408 is connected to the second magnetic block 405. The base 10 and the lower mold 20 are slidably connected, and the ends of the upper mold 401 and the lower mold 20 are magnetically connected. The slide rods 30 are symmetrically arranged on both sides of the lower mold 20. The mounting block 402 is slidably connected to the slide rods 30, and the upper mold 401 is slidably connected to the slide rods 30. The connecting rod 403 is set in an L-shape and is located on the outside of the base 10. The base 10 and the connecting rod 403 are slidably connected. The end of the baffle 406 is located at the bottom of the lower mold 20 and fits against it. The lower mold 20 and the baffle 406 are slidably connected. The baffle 406 and the base 10 are slidably connected. The positions of the first magnetic block 404 and the second magnetic block 405 are correspondingly arranged, and the first magnetic block 404 and the second magnetic block 405 have the same magnetic pole. The pipe 50 is set in an arc shape, and the end of the pipe 50 passes through the outside of the base 10.
[0034] The raw material is poured into the lower mold 20, and the cylinder 40 is activated. The cylinder 40 moves the upper mold 401 downward, causing the upper mold 401 to move the mounting blocks 402 on both sides downward. At this time, the mounting blocks 402 move downward on the surface of the slide rod 30, and the slide rod 30 guides the position of the upper mold 401. The upper mold 401 moves the connecting rod 403 downward, causing the connecting rod 403 to move the first magnetic block 404 downward. When the bottom of the upper mold 401 is in contact with the surface of the lower mold 20, the first magnetic block 404 moves to one side of the surface of the second magnetic block 405. Due to the thrust between the magnetic poles, the second magnetic block 405 is pushed outward by the first magnetic block 404, and the second magnetic block 405 moves the spring. When spring 408 extends, the end of magnetic block 405 drives baffle 406 to move outward, causing baffle 406 to move outward inside base 10. The end surface of baffle 406 loses its contact with the surface of lower mold 20. Since the ends of upper mold 401 and lower mold 20 are magnetically connected, cylinder 40 pushes upper mold 401 to move up and down, causing upper mold 401 to drive lower mold 20 to move upward, causing lower mold 20 to move downward inside base 10. The end of lower mold 20 presses spring 407 downward, causing spring 407 to contract and extend, which can vibrate between upper mold 401 and lower mold 20, shaking out air bubbles inside upper mold 401 and lower mold 20.
[0035] Hot air is introduced into the opening on one side of the pipe 50, allowing the hot air to flow inside the pipe 50. The base 10 can absorb the heat of the hot air and transfer the heat to the lower mold 20, heating the lower mold 20 and the raw material inside, thus forming the mold.
[0036] Then, condensate is introduced into the pipe 50 to cool the base 10 and the model inside the lower mold 20, preventing the temperature inside the lower mold 20 from becoming too high and facilitating the model's detachment from the lower mold 20.
[0037] Working principle: When using this injection compression device with a defoaming structure, a connecting rod 403, a magnetic block 1 404, a magnetic block 2 405, a baffle 406, and a spring 1 407 are provided to facilitate defoaming, improve the practicality of the device, and increase the overall usability.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
