Description

Technical Field

[0001] This utility model relates to the technical field of injection molding machine auxiliary demolding equipment, specifically to a device for assisting in the demolding of injection-molded products. Background Technology

[0002] Injection molding machines inject the required raw materials into the corresponding molds, where the materials cool and solidify, and then are ejected by a demolding mechanism. Patent number CN202321927282.0 discloses a device for assisting in the demolding of injection-molded products. During demolding, an electric push rod pushes an I-beam plate to allow a cutter to emerge from the cutter slot, cutting off the sprue material at the junction of the runner and mold cavity. This achieves separation of the sprue material from the mold during demolding, avoiding the need for subsequent external cutting, making the process more efficient, convenient, and flexible. However, while the material inside the mold cavity can be demolded by airflow through the pores, the sprue material remaining inside the runner is difficult to remove. Therefore, we propose a device for assisting in the demolding of injection-molded products. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a device for assisting in the demolding of injection-molded products from an injection molding machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is a device for assisting the demolding of injection molded products in injection molding machines, including a bottom mold body. The bottom mold body has a vertical hole connected to the flow channel of the mold cavity, and there are multiple sets of vertical holes. A guide washer is screwed into the inside of the vertical hole, and a T-shaped rod is inserted into the inside of the washer and slidably connected to the vertical hole. The bottom mold body has an L-shaped groove connected to the vertical hole, and there are multiple sets of L-shaped grooves. An L-shaped rod is slidably installed in the inside of the L-shaped groove and bolted to the T-shaped rod.

[0005] The bottom mold body is equipped with a T-shaped cylinder for support, and there are multiple sets of T-shaped cylinders. A support washer is slidably installed on the outer periphery of the T-shaped cylinder, and a spring for pushing the T-shaped rod to move is assembled between the washer and the T-shaped rod. A rotating seat for pushing the washer to move is screwed on the outer periphery of the T-shaped cylinder.

[0006] By adopting the above technical solution, during the use of the equipment for demolding injection molded products of the auxiliary injection molding machine, the rotating seat on the outer periphery of the T-shaped cylinder can be rotated, so that the rotating seat can be screwed and displaced on the outer periphery of the T-shaped cylinder and can easily push the spring through the washer ring. This facilitates the adjustment of the elasticity of the spring between the washer ring and the T-shaped rod, thereby making it convenient to adjust according to the needs of use, so that the spring can provide thrust to the T-shaped rod more stably.

[0007] When the top mold body and bottom mold body separate for demolding, the L-shaped rod inside the bottom mold body loses pressure after the top mold body separates, thereby relieving the downward pressure applied to the T-shaped rod inside the vertical hole. Subsequently, the spring on the outer circumferential washer surface of the T-shaped cylinder can provide thrust to the T-shaped rod, allowing one end of the T-shaped rod to pass through the washer and easily eject the sprue material in the mold cavity inside the bottom mold body, improving the convenience of sprue material demolding. At the same time, the L-shaped rod can also slide and move easily in the L-shaped groove. When the top mold body and bottom mold body abut and fit together, the top mold body can easily push the L-shaped rod out of the bottom mold body and retract it into the bottom mold body. This allows the L-shaped rod to push the T-shaped rod in the vertical hole to move and retract into the vertical hole. The top of the T-shaped rod can be flush with the inner wall of the bottom mold cavity and seal it, facilitating the smooth entry of the injection molding material into the mold cavity. This ensures that the demolding auxiliary structure does not affect the operation of the injection molding machine.

[0008] Specifically, the outer periphery of the T-shaped cylinder is provided with an arc-shaped groove that matches the gasket ring, and there are multiple sets of arc-shaped grooves.

[0009] By adopting the above technical solution, the multiple sets of arc grooves on the outer circumference of the T-shaped cylinder and the protrusions on the inner circumference of the washer ring fit together, so that the washer ring can slide more stably on the outer circumference of the T-shaped cylinder without rotating.

[0010] Specifically, a vertical shaft that is bolted to the T-shaped rod is slidably installed on the inner side of the T-shaped cylinder.

[0011] By adopting the above technical solution, the vertical shaft that slides on the inner circumference of the T-shaped cylinder can be easily connected to the T-shaped rod, making it easy to assemble and disassemble. This facilitates the guidance and support of the T-shaped rod's position and makes it easy to disassemble and replace the T-shaped rod.

[0012] Specifically, the bottom surface of the T-shaped cylinder is integrally constructed with a protruding rod that fits into the bottom mold body.

[0013] By adopting the above technical solution, the protruding rod at the bottom of the T-shaped cylinder can easily fit into the bottom mold body, which facilitates the improvement of the stability of the T-shaped cylinder during installation.

[0014] Specifically, a top mold body fits onto the top surface of the bottom mold body, and a T-shaped block that abuts against the L-shaped rod is screwed onto the side of the top mold body near the bottom mold body, and there are multiple sets of T-shaped blocks.

[0015] By adopting the above technical solution, the T-block on the top mold body is easy to disassemble and assemble, which facilitates protection against mutual rubbing between the L-shaped rod and the top mold body, thereby reducing the damage caused by rubbing when the L-shaped rod directly contacts the top mold body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of T-shaped cylinder, rotating seat, washer, spring and T-shaped rod, allows the rotating seat on the outer periphery of the T-shaped cylinder to rotate during the use of equipment that assists in demolding injection molded products on injection molding machines. This enables the rotating seat to be screwed and displaced on the outer periphery of the T-shaped cylinder and to easily push the spring through the washer. This facilitates the adjustment of the elasticity of the spring between the washer and the T-shaped rod, thereby making it easy to adjust according to the needs of use, so that the spring can provide thrust to the T-shaped rod more stably.

[0018] 2. The technical solution of this application, through the design of the top mold body, vertical hole, washer, L-shaped groove, and L-shaped rod, ensures that when the top mold body and bottom mold body separate for demolding, the L-shaped rod inside the bottom mold body loses pressure after the top mold body separates, thereby relieving the downward pressure applied to the T-shaped rod inside the vertical hole. Subsequently, the spring on the surface of the outer circumferential washer of the T-shaped cylinder can provide thrust to the T-shaped rod, allowing one end of the T-shaped rod to pass through the washer and facilitate the ejection of the sprue material in the mold cavity inside the bottom mold body, thus improving the convenience of sprue material demolding. The L-shaped rod is also convenient to slide and move within the L-shaped groove. When the top mold body and the bottom mold body abut and fit together, the top mold body can easily push the L-shaped rod out of the bottom mold body and retract it into the bottom mold body. This allows the L-shaped rod to push the T-shaped rod in the vertical hole to move and retract into the vertical hole. The top of the T-shaped rod can be flush with the inner wall of the bottom mold cavity and block it, facilitating the smooth entry of the injection plastic into the mold cavity. This ensures that the auxiliary demolding structure does not affect the operation of the injection molding machine. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1-3 This utility model provides a technical solution: a device for assisting in the demolding of injection-molded products in an injection molding machine, comprising a bottom mold body 1, a vertical hole 2 communicating with the flow channel of the mold cavity provided on the inner side of the bottom mold body 1, and multiple sets of vertical holes 2, a guide washer 3 screwed into the inner side of the vertical hole 2, and a T-shaped rod 4 slidably connected to the vertical hole 2 inserted into the inner side of the washer 3, an L-shaped groove 5 communicating with the vertical hole 2 provided on the inner side of the bottom mold body 1, and multiple sets of L-shaped grooves 5, an L-shaped rod 6 bolted to the T-shaped rod 4 slidably installed on the inner side of the L-shaped groove 5, and a T-shaped cylinder 7 for support assembled on the inner side of the bottom mold body 1, and multiple sets of T-shaped cylinders 7, a support washer ring 9 slidably installed on the outer periphery of the T-shaped cylinder 7, and a spring 10 for pushing the T-shaped rod 4 to move between the washer ring 9 and the T-shaped rod 4, and a rotating seat 8 for pushing the washer ring 9 to move by screwing into the outer periphery of the T-shaped cylinder 7.

[0026] When in use, during the process of using the equipment to assist in demolding injection molded products, the rotating seat 8 on the outer periphery of the T-shaped cylinder 7 can be rotated, so that the rotating seat 8 can be screwed and displaced on the outer periphery of the T-shaped cylinder 7 and can easily push the spring 10 through the washer ring 9. This facilitates the adjustment of the elasticity of the spring 10 between the washer ring 9 and the T-shaped rod 4, thereby making it easy to adjust according to the needs of use, so that the spring 10 can provide a more stable thrust to the T-shaped rod 4.

[0027] When the top mold body 14 and the bottom mold body 1 separate for demolding, the L-shaped rod 6 on the inner side of the bottom mold body 1 loses pressure after the top mold body 14 separates, thereby relieving the downward pressure applied to the T-shaped rod 4 on the inner side of the vertical hole 2. Subsequently, the spring 10 on the surface of the outer circumferential washer 9 of the T-shaped cylinder 7 can provide thrust to the T-shaped rod 4, allowing one end of the T-shaped rod 4 to pass through the washer 3 and easily eject the sprue material in the mold cavity inside the bottom mold body 1, which facilitates the demolding of the sprue material. At the same time, the L-shaped rod 6 also facilitates the ejection of the sprue material in the L-shaped groove 5. The top mold 14 and the bottom mold 1 are in contact and fit together. The top mold 14 can push the L-shaped rod 6 out of the bottom mold 1 and retract it into the bottom mold 1. This allows the L-shaped rod 6 to push the T-shaped rod 4 in the vertical hole 2 to move and retract into the vertical hole 2. The top of the T-shaped rod 4 can be flush with the inner wall of the bottom mold 1 cavity and block it, so that the plastic can be smoothly injected into the cavity. This ensures that the structure that assists in demolding will not affect the operation of the injection molding machine.

[0028] like Figure 3 As shown, the outer periphery of the T-shaped cylinder 7 is provided with an arc-shaped groove 11 that matches the gasket ring 9, and there are multiple sets of arc-shaped grooves 11.

[0029] During use, the multiple sets of arc grooves 11 on the outer periphery of the T-shaped cylinder 7 and the protrusions on the inner periphery of the washer ring 9 fit together, so that the washer ring 9 can slide more stably on the outer periphery of the T-shaped cylinder 7 without rotating.

[0030] like Figure 2 and Figure 3 As shown, a vertical shaft 13, which is bolted to the T-shaped rod 4, is slidably installed on the inner side of the T-shaped cylinder 7.

[0031] In use, the vertical shaft 13 that slides on the inner circumference of the T-shaped cylinder 7 can be easily connected to the T-shaped rod 4, making it easy to assemble and disassemble. This facilitates the guidance and support of the position of the T-shaped rod 4 and makes it easy to disassemble and replace the T-shaped rod 4.

[0032] like Figure 2 and Figure 3 As shown, the bottom surface of the T-shaped cylinder 7 is integrally constructed with a protruding rod 12 that matches the bottom mold body 1.

[0033] When in use, the protruding rod 12 at the bottom of the T-shaped cylinder 7 can easily fit into the bottom mold body 1, which helps to improve the stability of the T-shaped cylinder 7 during installation.

[0034] like Figure 2 As shown, a top mold 14 fits onto the top surface of the bottom mold 1, and a T-shaped block 15 that abuts against the L-shaped rod 6 is screwed onto the side of the top mold 14 near the bottom mold 1, and there are multiple sets of T-shaped blocks 15.

[0035] During use, the T-shaped block 15 on the top mold body 14 is easy to disassemble and assemble, which helps to protect the L-shaped rod 6 from rubbing against the top mold body 14, thereby reducing the damage caused by the L-shaped rod 6 rubbing against the top mold body 14.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the use of the equipment assisting in demolding injection-molded products, the rotating seat 8 on the outer periphery of the T-shaped cylinder 7 can be rotated, allowing the rotating seat 8 to engage and displace on the outer periphery of the T-shaped cylinder 7. This facilitates the pushing of the spring 10 through the washer ring 9, making it easy to adjust the elasticity of the spring 10 between the washer ring 9 and the T-shaped rod 4. This allows for convenient adjustment according to usage requirements, enabling the spring 10 to provide a more stable pushing force to the T-shaped rod 4. Simultaneously, when the top mold body 14 and the bottom mold body 1 separate for demolding, the L-shaped rod 6 on the inner side of the bottom mold body 1 loses pressure after the top mold body 14 separates, thereby releasing the downward pressure applied to the T-shaped rod 4 on the inner side of the vertical hole 2. Subsequently, the outer periphery of the T-shaped cylinder 7 can be demolded. The spring 10 on the surface of the washer 9 provides thrust to the T-shaped rod 4, allowing one end of the T-shaped rod 4 to pass through the washer 3 and easily eject the sprue material from the mold cavity inside the bottom mold body 1, thus improving the ease of demolding the sprue material. At the same time, the L-shaped rod 6 can also slide and move in the L-shaped groove 5. When the top mold body 14 and the bottom mold body 1 abut and fit together, the top mold body 14 can easily push the L-shaped rod 6 out of the bottom mold body 1 and retract it into the bottom mold body 1. This allows the L-shaped rod 6 to push the T-shaped rod 4 in the vertical hole 2 to move and retract it into the vertical hole 2. The top of the T-shaped rod 4 can be flush with the inner wall of the mold cavity of the bottom mold body 1 and block it, facilitating the smooth entry of the injection molding material into the mold cavity. This ensures that the structure that assists in demolding will not affect the operation of the injection molding machine.
