Description

Technical Field

[0001] This utility model belongs to the field of injection molding machine technology, and in particular relates to an injection molding machine with an oil baffle pad. Background Technology

[0002] Injection molding machines are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molding dies.

[0003] like Figure 6 As shown, this is an injection molding machine in the prior art. The inner side of the frame a is provided with an oil baffle. The oil storage tank of the oil baffle is open. When the demolding plate c separates from the demolding head plate d, the molded product in the mold will fall downwards. Smaller products will fall into the oil storage tank of the oil baffle, get contaminated with waste oil, and cause product pollution, increasing the difficulty of subsequent cleaning. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide an injection molding machine with an oil baffle pad. The structure is novel and can prevent small products from falling into the oil baffle without coming into contact with the waste oil in the oil storage tank, thus avoiding the product surface from being contaminated by waste oil.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An injection molding machine with an oil baffle plate includes: a frame, on which a pad and an oil baffle are mounted. The oil baffle has an oil reservoir for collecting lubricating oil flowing down from the surface of the pad. The oil baffle plate is placed inside the oil reservoir, with the side of the oil baffle plate closer to the pad higher than the side farther from the pad, so that the top surface of the oil baffle plate is inclined. This injection molding machine has a novel structure, preventing small products from falling into the oil baffle without contacting the waste oil in the oil reservoir, thus avoiding contamination of the product surface with waste oil.

[0006] Furthermore, the oil baffle pad includes a first support part, a guide part, and a second support part. The guide part is located between the first and second support parts, and the height of the first support part is greater than the height of the second support part, so that the guide part is inclined. With double-sided support, it has high stability. There is a certain height difference between the guide part and the inner bottom surface of the oil storage tank, preventing the guide part from being submerged by the collected lubricating oil. The guide part has very little oil on its surface, preventing small products from falling onto it and becoming contaminated with waste oil. The oil baffle pad has a simple structure and is highly practical.

[0007] Furthermore, the first support section, the guide section, and the second support section are integrally molded into a single structure, which allows for rapid molding, structural stability, and reliable use.

[0008] Furthermore, the oil baffle pad has evenly distributed oil leakage holes. Lubricating oil that falls onto the oil baffle pad flows into the oil storage tank through the oil leakage holes for collection, preventing lubricating oil from accumulating on the oil baffle pad.

[0009] Furthermore, the outer side of the pad is provided with an oil-blocking protrusion, which serves to block the oil from flowing out of the surface of the pad and increases the difficulty of collection.

[0010] Furthermore, the pad is provided with an oil guiding groove, the outlet of which is located above the oil storage tank. During the sliding of the second mold locking plate, the lubricating oil on the top surface of the oil baffle pad is pushed into the oil guiding groove, and the lubricating oil flows out of the oil guiding groove and falls into the oil storage tank for collection.

[0011] Furthermore, the width of the oil baffle pad is smaller than the width of the oil reservoir. There is a space between the oil baffle pad and the inner wall of the oil reservoir, so that the lubricating oil flowing down from the surface of the oil baffle pad falls into this space and does not flow outside the oil baffle.

[0012] Furthermore, the oil baffle is welded and fixed to the frame, ensuring a secure and stable installation that prevents it from easily loosening.

[0013] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects: 1. After injection molding is completed, the hydraulic cylinder drives the second mold clamping plate to slide in the opposite direction, so that the second mold clamping plate moves away from the mold clamping head plate, the mold one and the mold two separate, and the injection-molded product falls downward. When a smaller product falls into the oil baffle, it first lands on the oil baffle pad, and then slides down along the inclined top surface of the oil baffle pad to the bottom, and then falls into the discharge port to complete the product collection. The product will not come into contact with the waste oil in the oil storage tank, avoiding the product surface from being contaminated by waste oil, thereby reducing the difficulty of subsequent cleaning and solving the problem of smaller products falling into the oil baffle and getting contaminated with waste oil in the existing technology.

[0014] 2. The oil baffle pad is supported on both sides by the first and second support parts, ensuring high stability. There is a certain height difference between the guide part and the inner bottom surface of the oil storage tank to prevent the guide part from being immersed in the collected lubricating oil. There is very little oil on the surface of the guide part, which prevents small products from falling on the guide part and getting contaminated with waste oil. Attached Figure Description

Detailed Implementation

[0017] like Figure 1 As shown, this utility model discloses an injection molding machine with an oil-blocking strip and pad, comprising: a frame 1, a mold head plate 2, a mold second plate 3, a hydraulic cylinder, a pad 5, and an oil-blocking strip 6. The hydraulic cylinder and the mold head plate 2 are fixed on the frame 1. The output end of the hydraulic cylinder is connected to the mold second plate 3. A mold 7 is installed on the mold head plate 2, and a mold 8 that cooperates with the mold 7 is installed on the mold second plate 3. The pad 5 is located on both sides of the frame 1. An oil-blocking strip 6 and a material discharge port 9 are provided on the inner side of the frame 1. The oil-blocking strip 6 is symmetrically distributed and located above the material discharge port 9. The oil-blocking strip 6 is close to the inner side of the pad 5 and has an oil storage groove 10. The mold second plate 3 slides on the pad 5 through the support feet 11 at the bottom.

[0018] like Figure 2 and Figure 3 As shown, an oil baffle plate 12 is placed inside the oil storage tank 10. It is easy to remove and put in, and can be used immediately. The side of the oil baffle plate 12 closer to the shim 5 is higher than the side farther away from the shim 5, so that the top surface of the oil baffle plate 12 is inclined. The lowest point of the top surface of the oil baffle plate 12 is not lower than the side edge 13 of the oil baffle 6.

[0019] The outer side of the pad 5 is provided with an oil-blocking protrusion 14, which serves to block the oil from flowing out of the surface of the pad 5 and increase the difficulty of collection.

[0020] The hydraulic cylinder drives the second mold-locking plate 3 to slide forward, bringing it closer to the mold-locking head plate 2 until the first mold 7 and the second mold 8 are closed. During the sliding of the second mold-locking plate 3, the support leg 11 scrapes the lubricating oil on the surface of the pad 5, causing the lubricating oil to flow towards the inside of the pad 5 and fall into the oil storage groove of the oil baffle 6 for collection. After injection molding is completed, the hydraulic cylinder drives the second mold-locking plate 3 to slide in the opposite direction, moving it away from the mold-locking head plate 2. The first mold 7 and the second mold 8 separate, and the injection-molded product falls downward. When a smaller product falls into the oil baffle 6, it first lands on the oil baffle pad 12, then slides down along the sloping top surface of the oil baffle pad 12, and finally falls into the discharge port 9 to complete product collection. The product will not come into contact with the waste oil in the oil storage groove, avoiding contamination of the product surface with waste oil, thereby reducing the difficulty of subsequent cleaning and solving the problem of smaller products falling into the oil baffle 6 and getting contaminated with waste oil in the prior art.

[0021] like Figure 4 As shown, the oil baffle pad 12 includes a first support portion 15, a guide portion 16, and a second support portion 17. The guide portion 16 is located between the first support portion 15 and the second support portion 17. The second support portion 17 is close to the side 13 of the baffle. The height of the first support portion 15 is greater than the height of the second support portion 17, so that the guide portion 16 is inclined.

[0022] The oil baffle pad 12 is supported on both sides, ensuring high stability. There is a certain height difference between the guide part 16 and the inner bottom surface of the oil storage tank 10, preventing the guide part 16 from being immersed in the collected lubricating oil. The surface of the guide part 16 has very little oil, preventing small products from falling onto the guide part 16 and getting contaminated with waste oil. The oil baffle pad 12 has a simple structure and is highly practical.

[0023] The first support part 15, the guide part 16, and the second support part 17 are integrally formed, which allows for rapid molding, structural stability, and reliable use.

[0024] The width of the oil baffle pad 12 is smaller than the width of the oil reservoir 10. There is space between the first support 15 and the inner wall of the oil reservoir 10, and between the second support 17 and the inner wall of the oil reservoir 10. The lubricating oil flowing down from the surface of the oil baffle pad 12 falls into this space and does not flow out of the oil baffle 6.

[0025] like Figure 5 As shown, an oil guiding groove 18 is provided on the top surface of the pad 5, and the outlet of the oil guiding groove 18 is located above the oil storage tank 10. During the sliding process of the locking plate 3, the lubricating oil on the top surface of the oil baffle pad 12 is pushed into the oil guiding groove 18, and the lubricating oil flows out from the oil guiding groove 18 and falls into the oil storage tank 10 for collection.

[0026] The oil baffle 6 is welded and fixed to the frame 1, which is secure and not easy to loosen, thus ensuring the installation stability of the oil baffle 6.

[0027] Oil drain holes 19 are evenly distributed on the oil baffle pad 12. The diameter of the oil drain holes 19 is 3-5mm. The lubricating oil that falls on the oil baffle pad 12 flows into the oil storage tank 10 through the oil drain holes 19 for collection, so as to avoid the lubricating oil accumulating on the oil baffle pad 12.

[0028] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
