Description

Technical Field

[0001] This utility model relates to the technical field of material hoppers for injection molding machines, and specifically to a material feeding mechanism for injection molding machines with a material feeding structure. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting plastics. The material used for injection molding mainly enters the injection mechanism through the hopper.

[0003] Currently, the hoppers used in injection molding machines are generally funnel-shaped structures that are wider at the top and narrower at the bottom. This makes it easy for particles to crowd each other and cause blockages or slow material feeding when entering the injection mechanism, thus reducing feeding efficiency. Therefore, a feeding mechanism for injection molding machines with a material-promoting structure is proposed. This mechanism uses vibration to promote material feeding, thereby avoiding blockages and improving feeding efficiency. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides a feeding mechanism for injection molding machines with a material feeding structure, which promotes material feeding through vibration operation, thereby avoiding blockage and improving feeding efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is a feeding mechanism for an injection molding machine with a feeding structure, including a support bottom ring, a shaking component and a buffer component. A feeding sleeve is welded to the top center of the support bottom ring. A feeding hopper is provided at the top of the feeding sleeve. A support ring is welded to the bottom end of the feeding hopper. A discharge pipe is welded to the bottom center of the support ring.

[0006] The vibration assembly includes a high-speed electric cylinder and a bracket, and the buffer assembly includes an upper support block, a lower support block, and a spring.

[0007] By adopting the above technical solution, the feeding hopper is used to collect the injection molding material, and the corresponding bracket support ring is driven by a high-speed electric cylinder to drive the feeding hopper to shake up and down at high speed. This causes the feeding tube to shake up and down synchronously inside the feeding sleeve, so as to promote the material to enter the injection system, thereby avoiding blockage and effectively improving the feeding efficiency.

[0008] The upper and lower support blocks are welded to the top and bottom of the spring, respectively, so that the support spring can be fixed between the support ring and the feeding sleeve. When the support ring and the feeding pipe vibrate up and down at high speed inside the feeding sleeve, the elasticity of the spring is used to provide auxiliary support and achieve a buffering effect.

[0009] Specifically, the bottom end of the feeding pipe penetrates the inside of the feeding sleeve.

[0010] By adopting the above technical solution, a material accelerator sleeve is used to connect to the outside of the material discharge pipe.

[0011] Specifically, the high-speed electric cylinders are all fixed to the top of the support ring on both sides of the corresponding material accelerator sleeve by bolts, the brackets are all welded to both sides of the support ring, and the drive ends of the high-speed electric cylinders are all connected to the brackets.

[0012] By adopting the above technical solution, a high-speed electric cylinder is used to drive the bracket to support the support ring, which in turn drives the feed hopper to vibrate up and down at high speed, thereby promoting the feeding effect.

[0013] Specifically, the upper support block, the lower support block, and the spring are all provided in two sets. The springs are all welded between the upper support block and the lower support block. The upper support blocks are all fixed to both sides of the bottom of the support ring by bolts. The lower support blocks are all fixed to both sides of the top of the accelerator sleeve corresponding to the feed pipe by bolts.

[0014] By adopting the above technical solution, the upper support block and the lower support block are welded to the top and bottom of the spring respectively, so as to support the spring to be fixed between the support ring and the accelerator sleeve.

[0015] Specifically, the top surface of the support base ring is provided with fixing holes evenly distributed around the center position.

[0016] By adopting the above technical solution, the fixing holes are used to facilitate the installation and fixing of the support base ring to the outside of the inlet of the injection system of the injection molding machine.

[0017] The beneficial effects of this utility model are:

[0018] The present invention discloses a feeding mechanism for an injection molding machine with a material-accelerating structure. The feeding hopper collects the injection molding material, and a high-speed electric cylinder simultaneously drives the corresponding bracket to support the support ring, causing the feeding hopper to vibrate up and down at high speed. This causes the feeding tube to vibrate up and down synchronously inside the material-accelerating sleeve, thereby promoting the material to enter the injection system, thus avoiding blockage and effectively improving the feeding efficiency.

[0019] The present invention describes a feeding mechanism for an injection molding machine with a feeding structure. The upper support block and the lower support block are welded to the top and bottom of the spring, respectively, so as to support the spring to be fixed between the support ring and the feeding sleeve. When the support ring and the feeding tube vibrate up and down at high speed inside the feeding sleeve, the elasticity of the spring is used to provide auxiliary support and achieve a buffering effect.

[0025] 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.

[0026] To avoid clogging and improve feeding efficiency, such as Figure 1-3 As shown, the feeding mechanism for an injection molding machine with a feeding structure according to this utility model includes a support bottom ring 1, a shaking component 7 and a buffer component 8. A feeding sleeve 2 is welded to the top center of the support bottom ring 1. A feeding hopper 4 is provided at the top of the feeding sleeve 2. A support ring 5 is welded to the bottom end of the feeding hopper 4. A discharge pipe 6 is welded to the bottom center of the support ring 5.

[0027] The vibration component 7 includes a high-speed electric cylinder 701 and a bracket 702, and the buffer component 8 includes an upper support block 801, a lower support block 802 and a spring 803.

[0028] In use, the feeding hopper 4 is used to collect the injection molding material, and the high-speed electric cylinder 701 simultaneously drives the corresponding bracket 702 to support the support ring 5, causing the feeding hopper 4 to vibrate up and down at high speed. This causes the feeding pipe 6 to vibrate up and down synchronously inside the feeding sleeve 2, so as to promote the material to enter the injection system, thereby avoiding blockage and effectively improving the feeding efficiency.

[0029] The upper support block 801 and the lower support block 802 are welded to the top and bottom of the spring 803 respectively, so as to support the spring 803 to be fixed between the support ring 5 and the feeding sleeve 2. When the support ring 5 and the feeding pipe 6 vibrate up and down at high speed inside the feeding sleeve 2, the elasticity of the spring 803 is used to provide auxiliary support and achieve a buffering effect.

[0030] To avoid clogging and improve feeding efficiency, for example, such as Figure 1 , Figure 3 As shown, the present invention also includes a bottom end of the feeding pipe 6 penetrating the inner side of the feeding sleeve 2.

[0031] In use, the feeding sleeve 2 is connected to the outside of the feeding pipe 6.

[0032] For example, such as Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes the following: the high-speed electric cylinders 701 are all fixed to the top of the support base ring 1 on both sides of the corresponding material accelerator sleeve 2 by bolts; the brackets 702 are all welded to both sides of the support ring 5; and the drive ends of the high-speed electric cylinders 701 are all connected to the brackets 702.

[0033] During use, the high-speed electric cylinder 701 drives the bracket 702 to support the support ring 5, which in turn drives the feed hopper 4 to vibrate up and down at high speed to promote the feeding effect.

[0034] For example, such as Figure 1 , Figure 3 As shown, this utility model also includes two sets of the upper support block 801, the lower support block 802 and the spring 803. The spring 803 is welded between the upper support block 801 and the lower support block 802. The upper support block 801 is fixed to both sides of the bottom of the support ring 5 by bolts. The lower support block 802 is fixed to both sides of the top of the feeding sleeve 2 corresponding to the feeding pipe 6 by bolts.

[0035] In use, the upper support block 801 and the lower support block 802 are welded to the top and bottom of the spring 803 respectively, so as to support the spring 803 to be fixed between the support ring 5 and the accelerator sleeve 2.

[0036] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes fixing holes 3 evenly distributed around the center position on the outer periphery of the top surface of the support base ring 1.

[0037] During use, the support base ring 1 is installed and fixed to the outside of the inlet of the injection system of the injection molding machine through the fixing hole 3.

[0038] In use, the supporting bottom ring 1 is installed and fixed to the outer periphery of the inlet of the injection system of the injection molding machine through the fixing hole 3.

[0039] The feeding hopper 4 collects the injection molding material, and the high-speed electric cylinder 701 simultaneously drives the corresponding bracket 702 to support the support ring 5, causing the feeding hopper 4 to vibrate up and down at high speed. This causes the feeding pipe 6 to vibrate up and down synchronously inside the feeding sleeve 2, thereby promoting the material to enter the injection system, thus avoiding blockage and effectively improving the feeding efficiency.

[0040] The upper support block 801 and the lower support block 802 are welded to the top and bottom of the spring 803 respectively, so as to support the spring 803 to be fixed between the support ring 5 and the feeding sleeve 2. When the support ring 5 and the feeding pipe 6 vibrate up and down at high speed inside the feeding sleeve 2, the elasticity of the spring 803 is used to provide auxiliary support and achieve a buffering effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
