Description

Technical Field

[0001] This utility model belongs to the technical field of injection molds, specifically relating to a slider core-pulling system for injection molds with multiple ejection directions. Background Technology

[0002] The automotive sub-instrument assembly refers to the control and storage platform located between the driver and passenger seats. It is typically manufactured using injection molding. With the rapid development of the automotive industry, the quality requirements for plastic parts in automotive sub-instrument assemblies are becoming increasingly stringent, necessitating continuous updates and improvements to the injection molding process. The slider mechanism is one of the most important mechanisms in injection molds, primarily used for forming undercut structures in products with different ejection directions. However, when a product requires undercut structures with two or more ejection directions, conventional sliders cannot achieve this. For example, the slider mechanism surrounding sub-instrument assemblies and similar structural products primarily functions to form undercut structures with multiple different ejection directions, a task that cannot be accomplished using conventional slider mechanisms. Utility Model Content

[0003] The purpose of this invention is to provide a slider core-pulling system for injection molds with multiple ejection directions, in order to solve the above-mentioned problems.

The drive mechanism drives the slider head to move linearly. Several slanted ejector assemblies are arranged at the rear center of the slider head. The front ends of the slanted ejector assemblies pass through the slider head and abut against the product, and the rear ends are connected to the fixing plate through the rear ends of the slanted ejector assembly fixing block. A spring mechanism is provided between the rear ends of the slanted ejector assembly fixing block and the fixing plate. The fixing plate is fixedly connected to the moving mold plate.

[0006] The front end of the inclined top component fixing block is located below the slider head, and a groove is provided in the middle of the inclined top component fixing block along its length. The slider head is correspondingly provided with a lever block that slides through the groove. A fixing block is provided on the inclined top component fixing block behind the groove, and a spring block is correspondingly provided on the moving template behind the fixing block. The spring block is used to prevent the fixing block from retracting, thereby preventing the inclined top component fixing block from retracting. The lever block is used to move with the slider head to the rear side of the groove, and the free end of the lever block passes through the fixing block and presses down on the spring block with an inclined surface. Specifically, the front ends of the several inclined top components are formed in a local product direction different from the slider movement direction, and cooperate with the slider head to ensure smooth movement. The several inclined top components are all prior art and are not the focus of this utility model improvement, so they will not be described in detail.

[0007] To better realize this utility model, the driving mechanism further includes a support plate and an oil cylinder, and the two sides of the slider head are respectively connected to the driving end of the oil cylinder through the support plate.

[0008] To better realize this utility model, the system further includes a first inclined top assembly, a second inclined top assembly, and a third inclined top assembly arranged sequentially from left to right; the first inclined top assembly is connected to a fixed plate through a first inclined top assembly fixing block, and the second and third inclined top assemblies are respectively connected to the fixed plate through a second inclined top assembly fixing block.

[0009] To better realize this utility model, the first inclined top component and the third inclined top component are arranged in parallel, and the second inclined top component is arranged at an angle.

[0010] To better realize this utility model, a middle support is further provided between the rear end of the inclined top component fixing block and the fixing plate, and the middle support is fixed to the fixing plate.

[0011] To better realize this utility model, the spring mechanism further includes a mounting column, a limiting plate, and a spring. The limiting plate is sleeved on the bottom of the mounting column, and a spring is sleeved on the outer side of the mounting column. A spring is provided between the limiting plate and the rear end of the inclined top component fixing block.

[0012] To better realize this utility model, a limit switch is further provided on the support plate on one side of the bottom of the fixing plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention enables core pulling with an undercut structure in multiple ejection directions, ensuring structural safety and reliability. Furthermore, it refines the division of related components, reducing their interrelationships, thereby lowering processing and material costs and simplifying assembly, resulting in greater practicality. Additionally, this invention features a simple and practical structure, convenient installation, high production efficiency, and relatively low development and production costs.

Detailed Implementation

[0028] Example 1:

[0029] A slider core-pulling system for injection molds with multiple ejection directions, such as Figure 1 As shown, it includes a slider head 1 located on the front side and a fixed plate 8 located on the rear side, the fixed plate 8 being fixedly connected to the moving template. Figure 7 As shown, a first inclined top assembly 4, a second inclined top assembly 5, and a third inclined top assembly 6 are sequentially arranged from left to right between the slider head 1 and the fixing plate 8. The front ends of the first inclined top assembly 4, the second inclined top assembly 5, and the third inclined top assembly 6 pass through the slider head and abut against the product, and their rear ends are respectively connected to the rear ends of the inclined top assembly fixing block 7. Figure 1 and Figures 8-10 As shown, the rear end of the inclined top assembly fixing block 7 is connected to the fixing plate 8 via a spring mechanism 10. The middle support 9 is fixed to the fixing plate 8, as shown. Figure 11 As shown, the aforementioned middle torso 9 is existing technology, so it will not be described in detail here.

[0030] Preferably, the push block 11 is fixed to the slider head 1, the fixing block 12 is fixed to the inclined top assembly fixing plate 8, the spring block 13 is fixed to the moving template, and the limit switch 14 is connected to the fixing plate 8.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, the front end of the inclined top component fixing block 7 is located below the slider head 1, and a groove is provided in the middle of the inclined top component fixing block 7 along the length direction. Figures 3-5 As shown, the slider head 1 is correspondingly provided with a lever block 11 that is slidably connected to the slide groove. A fixing block 12 is provided on the inclined top assembly fixing block 7 on the rear side of the slide groove. A spring block 13 is correspondingly provided on the moving template, located behind the fixing block 12. The spring block 13 is used to prevent the fixing block 12 from retracting, thereby preventing the inclined top assembly fixing block 7 from retracting. The lever block 11 is used to move with the slider head 1 to the rear side of the slide groove, and the free end of the lever block 11 passes through the fixing block 12 and presses down on the spring block 13 with its inclined surface. Figure 1 and Figure 6 As shown, a limit switch 14 is provided on the support plate 2 on one side of the bottom of the fixing plate 8.

[0032] Preferably, such as Figures 1-3 As shown, a support plate 2 and a hydraulic cylinder 3 are respectively provided on both sides of the slider head 1. The support plate 2 is fixed to the slider head 1, and the hydraulic cylinder 3 is connected to the support plate 2.

[0033] Preferably, such as Figure 4 , Figure 8 and Figure 9 As shown, the first inclined top assembly 4 is connected to the fixed plate 8 via the first inclined top assembly fixing block 7, and the second inclined top assembly 5 and the third inclined top assembly 6 are respectively connected to the fixed plate 8 via the second inclined top assembly fixing block 7. Figure 8 The arrows in the diagram indicate the movement direction of the inclined push rod and the inclined push head in the inclined push assembly, which completes the reverse core pulling along the slider exit direction.

[0034] Preferably, such as Figure 12 As shown, the spring mechanism 10 includes a mounting post, a limiting plate, and a spring. The limiting plate is sleeved on the bottom of the mounting post, and a spring is sleeved on the outer side of the mounting post. A spring is provided between the limiting plate and the rear end of the inclined top assembly fixing block 7.

[0035] The working principle of this utility model is as follows: After the mold opens, the hydraulic cylinder 3 provides power to drive the slider head 1 and the pusher block 11 to move backward through the support plate 2. At this time, the spring block 13 is in a popped-up state, which hinders the backward movement of the fixed block 12 and the inclined ejector assembly fixed block 7. The backward movement of the slider head 1 drives the first inclined ejector assembly 4, the second inclined ejector assembly 5, and the third inclined ejector assembly 6 to move in the inclined ejector core-pulling direction, completing the inverted core-pulling in different directions. When the free end of the pusher block 11 passes the fixed block 12, it contacts the spring block 13 with its inclined surface, pressing the spring block 13 downward, so that its obstruction of the backward movement of the fixed block 12 is invalidated. At this time, the hydraulic cylinder 3 drives the slider head 1, the inclined ejector assembly fixed plate 8, and the first inclined ejector assembly 4, the second inclined ejector assembly 5, and the third inclined ejector assembly 6 to move together and detach from the product through the support plate 2. Until the support plate 2 touches the limit switch 14, the hydraulic cylinder 3 stops providing power, and the core-pulling action is completed.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
