Description

Technical Field

[0001] This utility model relates to the technical field of injection molding machine frames, specifically to an injection molding machine hardware frame with a noise reduction structure. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are often referred to as "cream molding machines" in many factories, and injection-molded products are called "cream molded parts." They are the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds.

[0003] Injection molding machines generate significant vibration and noise problems during operation. Traditional injection molding machine frames have simple structures and lack effective noise reduction measures. Strong vibrations not only affect the stability and lifespan of the frame itself but also transmit to surrounding equipment, interfering with its normal operation and increasing equipment failure rates. The excessive noise exceeds industrial environmental noise standards, damaging the hearing health of operators and reducing the comfort and safety of the working environment. Furthermore, noise pollution may trigger complaints from nearby residents, restricting the company's production time and scale, and hindering sustainable development. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an injection molding machine hardware frame with a noise reduction structure, thereby solving the technical problem that the aforementioned strong vibrations not only affect the stability and service life of the frame itself, but also transmit to surrounding equipment, interfering with its normal operation and increasing the equipment failure rate.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a metal frame for an injection molding machine with a noise reduction structure, comprising: an assembly frame, columns, a top frame, and a metal frame. The top frame is assembled on the outside of the assembly frame, the columns are evenly distributed between the assembly frame and the top frame, and the metal frame is slidably disposed on the outside of the columns. A noise reduction mechanism is assembled between the metal frame and the columns.

[0008] The noise reduction mechanism includes a rubber sleeve, a partition is installed inside the rubber sleeve, an oil inlet is connected to the top of the rubber sleeve, a noise reduction block is installed inside the rubber sleeve, exhaust ports are evenly distributed on the outside of the rubber sleeve, and a sound-absorbing layer is sleeved on the outside of the metal frame.

[0009] Preferably, the rubber sleeve and the partition are both fitted onto the outside of the column. The noise reduction mechanism can buffer and reduce noise between the metal frame and the assembly frame, and at the same time lubricate the metal frame and the column.

[0010] Preferably, the noise reduction block has a memory foam embedded inside, and a hollow groove is formed inside the noise reduction block. The hollow groove is grid-shaped. The memory foam improves the return effect of the rubber sleeve and the noise reduction block. At the same time, the rubber sleeve is made of rubber, which can improve the damping coefficient of the noise reduction mechanism itself.

[0011] Preferably, the assembly frame is equipped with an airbag inside, and the airbag is filled with air. The airbag can effectively prevent noise and vibration caused by the impact between the metal frame and the assembly frame.

[0012] Preferably, the top frame has an injection port on its exterior, and a sealing ring is embedded inside the injection port, which can be connected to an external injection molding machine.

[0013] Preferably, both ends of the rubber sleeve are connected to sealing sleeves, and the sealing sleeves are slidably connected to the column. The sealing sleeves can be slidably connected to the column to improve the sealing performance between the noise reduction mechanism and the column.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a metal frame for injection molding machines with a noise reduction structure, which has the following beneficial effects:

[0016] This injection molding machine frame with a noise reduction structure significantly reduces noise and vibration through the addition of a noise reduction mechanism and a sound-absorbing layer, utilizing internal mesh and honeycomb slot designs. It effectively absorbs and disperses vibrations, reduces noise propagation, improves the working environment, protects operators' hearing, and reduces interference with surrounding equipment, thereby enhancing overall stability. Furthermore, this solution reduces the impact of vibrations on the assembly frame and connecting components, minimizing wear and fatigue damage, thus extending the frame's service life, reducing equipment maintenance and replacement costs, and improving the injection molding machine's operational reliability. Simultaneously, while reducing vibration and noise, the noise reduction mechanism also lubricates the exterior of the columns, preventing reduced lifespan and noise generation due to insufficient lubrication between the metal frame and the columns.

[0022] 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.

[0023] This utility model provides a technical solution; please refer to [link / reference]. Figure 1 and Figure 2 A hardware frame for an injection molding machine with a noise reduction structure includes: an assembly frame 1, columns 2, a top frame 3, and a metal frame 4. The top frame 3 is assembled on the outside of the assembly frame 1. The columns 2 are evenly distributed between the assembly frame 1 and the top frame 3. The metal frame 4 is slidably disposed on the outside of the columns 2. A noise reduction mechanism 5 is assembled between the metal frame 4 and the columns 2.

[0024] The assembly frame 1, column 2, top frame 3 and metal frame 4 are common hardware frames for injection molding machines in the prior art, used to support and assemble the injection molding machine. The assembly frame 1 can work with the column 2 to guide the metal frame 4. The metal frame 4 can be driven to slide by a cylinder. The noise reduction mechanism 5 can reduce noise and vibration on the outside of the metal frame 4.

[0025] The noise reduction mechanism 5 includes a rubber sleeve 51, a partition 55 is installed inside the rubber sleeve 51, an oil inlet 53 is connected to the top of the rubber sleeve 51, a noise reduction block 56 is installed inside the rubber sleeve 51, exhaust ports 54 are evenly distributed on the outside of the rubber sleeve 51, and a sound-absorbing layer 41 is sleeved on the outside of the metal frame 4.

[0026] Please see Figure 3 and Figure 4 The rubber sleeve 51 has high damping characteristics due to its material. The oil inlet 53 is a common air inlet in the prior art. A needle can be inserted into it to inject lubricating oil. After the injection is completed, the rubber sleeve 51 can be sealed. The exhaust port 54 can expel the gas inside the rubber sleeve 51 when the noise reduction block 56 is squeezed, which accelerates the air flow outside the assembly frame 1 and then cools and removes odors. The partition 55 can divide the interior of the rubber sleeve 51 into two parts. The sound-absorbing layer 41 has holes evenly distributed inside, and the holes are filled with honeycomb-shaped sound-absorbing materials such as sound-absorbing cotton and foam aluminum.

[0027] Both the rubber sleeve 51 and the partition plate 55 are fitted onto the outside of the column 2. The noise reduction mechanism 5 can buffer and reduce noise between the metal frame 4 and the assembly frame 1, and at the same time lubricate between the metal frame 4 and the column 2. The noise reduction block 56 is embedded with memory foam. The noise reduction block 56 has a hollow groove, and the hollow groove is grid-shaped. The memory foam improves the return effect of the rubber sleeve 51 and the noise reduction block 56. At the same time, the rubber sleeve 51 is made of rubber, which can improve the damping coefficient of the noise reduction mechanism 5 itself.

[0028] The assembly frame 1 is equipped with an airbag 11, which is filled with air. The airbag 11 can effectively prevent noise and vibration caused by the impact between the metal frame 4 and the assembly frame 1. The top frame 3 has an injection port 31 on its outside. The injection port 31 is fitted with a sealing ring. The injection port 31 can be connected to an external injection molding machine.

[0029] Both ends of the rubber sleeve 51 are connected to sealing sleeves 52, and the sealing sleeves 52 are slidably connected to the column 2. The sealing sleeves 52 can be slidably connected to the column 2 to improve the sealing performance between the noise reduction mechanism 5 and the column 2.

[0030] This solution connects the injection molding machine to the top frame 3 and the external cylinder to the metal frame 4. The cylinder drives the metal frame 4 to move the mold. During movement, the noise reduction mechanism 5 slides outside the metal frame 4. When the column 2 moves, the internal hollow design of the noise reduction block 56, along with the combination of memory foam and rubber sleeves, utilizes its high elasticity and high damping characteristics to effectively absorb and disperse vibration energy, enhancing the shock absorption effect, reducing vibration transmission, and thus reducing noise generation. Simultaneously, during the movement of the metal frame 4… Furthermore, the external sound-absorbing layer 41, with its honeycomb-shaped grooves, reflects and absorbs the noise generated when the metal frame 4 moves multiple times, effectively reducing the vibration and noise generated when the injection molding machine is working. At the same time, the noise reduction mechanism 5 reduces the collision between the noise reduction mechanism 5 and the assembly frame 1 when the metal frame 4 moves. Also, when the noise reduction mechanism 5 collides with the assembly frame 1, the internal lubricating oil is squeezed and adheres to the outside of the column 2, thereby improving the smoothness of the metal frame 4's operation and preventing noise generated by the movement of the metal frame 4 due to lack of lubrication.

[0031] By incorporating a noise reduction mechanism 5 and a sound-absorbing layer 41, which utilize internal mesh and honeycomb slot designs respectively, noise and vibration are significantly reduced. This effectively absorbs and disperses vibrations, reduces noise propagation, improves the working environment, protects operators' hearing, reduces interference with surrounding equipment, and enhances overall stability. It also extends equipment lifespan: reducing the impact of vibration on the assembly frame 1 and connecting components reduces wear and fatigue damage, extends the frame's lifespan, lowers equipment maintenance and replacement costs, and improves the reliability of the injection molding machine. Simultaneously, the noise reduction mechanism 5, while reducing vibration and noise, also lubricates the exterior of the column 2, preventing reduced lifespan and noise generation due to insufficient lubrication between the metal frame 4 and the column 2.
