Double-rod angle ejection structure with inclined ejection block

By using the double-rod structure of the inclined ejector block, the ejection force is decomposed by the inclined connecting rod and the sliding bottom slide, which solves the problems of jamming and increased stroke when the traditional inclined ejector block ejects at a large angle. This results in a shorter ejection stroke and lower frictional resistance, extending the mold's service life and reducing costs.

Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp moulds, in particular to a structure using an inclined ejector block and double rods for angle ejection. Background Art

[0002] In the field of mold design for headlights, for some special products, the inclined ejector block is usually used to assist in ejecting the corresponding products. The traditional inclined ejector block mechanism is generally a single-rod single-angle ejection structure, which is installed between the ejector plate and the rear mold of the mold assembly, and relies on the movement of the ejector plate during ejection to drive the inclined ejector rod and the inclined ejector block. However, due to the relatively simple linkage structure or slide seat between the inclined ejector rod and the ejector plate of the ordinary inclined ejector structure, when the inclined ejector angle is large, the friction resistance of the inclined ejector rod will also increase, and the force is uneven during the inclined ejection, which is easy to cause the ejector rod to get stuck or roughened. The stroke of the inclined ejector will also increase, increasing the risk of getting stuck. Even if the angle is too large, the ejector rod is prone to breakage and bending, which is not conducive to the service life of the mechanism and will increase a lot of maintenance costs. At the same time, in the process of mold production, sometimes the product undercut is too long. If the stroke of the inclined ejector is large, the undercut may be broken or deformed too much, which cannot meet the product requirements; in addition, the stroke of the inclined ejector is large, and the mold foot needs to be relatively large, and the size and cost of the entire mold assembly will also increase. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a structure for ejecting with a double rod of an inclined ejector block at an angle, which can solve the problem of the ejector rod being stuck when the inclined ejector block ejects a large angle structure and reduce the ejection stroke of the inclined ejector block.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A structure for double-rod angle ejection using an inclined ejector block, comprising a connecting rod fixedly arranged in a mold assembly, a bottom slide seat slidably arranged on an ejector pin plate of the mold assembly, an inclined ejector rod guided and movably arranged in the mold assembly, and an inclined ejector block arranged at the top of the inclined ejector rod;

[0006] The bottom slide is provided with an inclined top seat obliquely, the bottom end of the inclined top rod is slidably connected to the inclined top seat, the connecting rod is arranged obliquely and in the opposite direction of the inclined top rod, and the connecting rod also obliquely passes through the bottom slide;

[0007] When the ejector plate moves, the bottom slide seat can slide obliquely along the connecting rod and slide horizontally relative to the ejector plate, and the inclined ejector rod can slide relative to the inclined ejector seat and drive the inclined ejector block to obliquely eject the product under the lifting action.

[0008] Furthermore, a sliding block is detachably mounted on the bottom end of the inclined ejector rod, and the sliding block is slidably connected to the inclined ejector seat.

[0009] Furthermore, the inclined top seat and the bottom sliding seat are fastened by locking screws and positioned by pins.

[0010] Furthermore, a guide seat is provided in the bottom slide seat and is slidably matched with the connecting rod.

[0011] Furthermore, the upper and lower ends of the connecting rod are installed through fixing seats.

[0012] Furthermore, a sliding sheet is arranged between the bottom of the bottom slide seat and the ejector plate.

[0013] Furthermore, a limited position slide is provided between the side wall of the bottom slide seat and the ejector plate.

[0014] By adopting the above technical solution, the utility model has the following beneficial effects:

[0015] The cam is designed to slide with the bottom end of the cam being moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod and the bottom end of the cam are moved in a camming motion so that the camming rod

[0016] 2. The utility model is different from the traditional inclined ejector structure. When the ejector plate ejects the same height, due to the sliding design of the bottom slide, the inclined ejector rod and the inclined ejector block can obtain a shorter ejection stroke. Therefore, even when the inclined ejection angle is large, it is not easy for the ejector rod to get stuck, break or bend. At the same time, when the product undercut is too long, it is not easy to pull the undercut off, which reduces the impact on the product, protects the product, and is easier to meet the requirements.

DETAILED DESCRIPTION

[0024] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0025] like Figure 1-4 As shown, in this embodiment, a structure for ejection with an inclined ejector block and double rods at an angle is provided, which is mainly composed of an inclined ejector block 1, an inclined ejector rod 2, a bottom slide 3, an inclined ejector seat 4, a connecting rod 5 and other components. This embodiment is generally installed inside a mold assembly, the inclined ejector rod 2 is slidably installed on the rear mold 7 through a guide seat, and the inclined ejector rod 2 passes through the top of the rear mold 7 to fix the inclined ejector block 1 for ejecting products; the upper end of the connecting rod 5 is installed and fixed on the bottom of the rear mold 7 through a fixing seat 50, and the lower end of the connecting rod 5 is installed and fixed on the bottom plate 8 through the fixing seat 50, and the bottom plate 8 and the rear mold 7 are connected by a mold foot 9, and there is also an ejector plate 6 that can move up and down between the bottom plate 8 and the rear mold 7; and the bottom slide 3 is horizontally slidably arranged on the ejector plate 6, and the inclined ejector seat 4 is tiltedly arranged on the bottom slide 3, the bottom end of the inclined ejector rod 2 is slidably connected to the inclined ejector seat 4, and the connecting rod 5 is also tiltedly arranged and opposite to the tilt direction of the inclined ejector rod 2, and at the same time, the connecting rod 5 also tilts through the bottom slide 3.

[0026] refer to Figure 3 , 4As shown, when the embodiment is working, that is, when the ejector plate 6 is lifted, the bottom slide 3 can be driven to be lifted upward, and the lifting of the bottom slide 3 will drive the inclined ejector seat 4 to drive the inclined ejector rod 2 and the inclined ejector block 1 to be lifted along the guide direction and eject the product, and the bottom of the inclined ejector rod 2 and the inclined ejector seat 4 can slide relative to each other; at the same time, under the action of the inclined connecting rod 5, the bottom slide 3 will slide along the connecting rod 5 and slide horizontally relative to the ejector plate 6. This is different from the traditional inclined ejector structure. The bottom slide 3 and the inclined ejector seat 4 can move horizontally under the action of the connecting rod 5 when they are lifted. Under the protection of the connecting rod 5, the ejection force can be effectively decomposed and the angle delay effect can be achieved, so that the force on the inclined ejector rod 2 is more balanced, and the friction resistance can be appropriately reduced. Therefore, when the inclined ejector angle is large, the possibility of the ejector rod being stuck or roughened can be reduced, which effectively extends the service life of the mechanism and reduces the maintenance cost. In addition, this embodiment is different from the traditional inclined ejector structure. When the ejector plate 6 is ejected to the same height, due to the sliding design of the bottom slide 3 and the inclined track design of the inclined ejector seat 4, the inclined ejector rod 2 and the inclined ejector block 1 can obtain a shorter ejection stroke. Therefore, even when the inclined ejector angle is large, it is not easy for the ejector rod to get stuck, break or bend. At the same time, when the undercut of the product is too long, it is not easy to pull the undercut off, which reduces the impact on the product, protects the product, and is easier to meet the requirements. Of course, compared with the traditional inclined ejector structure, the ejection stroke of this embodiment is shorter, so the mold foot 9 can be designed to be shorter, reducing material costs and reducing the size of the mold assembly.

[0027] Specifically, the bottom end of the inclined ejector rod 2 of this embodiment is detachably equipped with a slider 20, and an inclined slide rail is provided on the inclined ejector seat 4, and the slider 20 is slidably connected with the slide rail in the inclined ejector seat 4. The slider 20 is fastened to the bottom end of the inclined ejector rod 2 by screws, so it is convenient to disassemble and assemble.

[0028] In order to facilitate the rapid adjustment and modification of the ejection angle and stroke, the inclined ejector seat 4 and the bottom slide seat 3 of this embodiment are fastened by a locking screw 40, which is convenient and quick to disassemble and replace, and is positioned by a pin 30 to ensure stability.

[0029] In order to ensure the sliding stability of the bottom slide 3 and prevent it from shaking, a guide seat 10 is also provided in the bottom slide 3 of the present embodiment, which is slidably matched with the connecting rod 5. At the same time, a slide groove is provided on the ejector plate 6 to match the bottom slide 3, a slide sheet 61 is added between the bottom of the bottom slide 3 and the ejector plate 6, and a limit slide 62 is added between the side wall of the bottom slide 3 and the ejector plate 6, so as to reduce the sliding friction of the bottom slide 3 and ensure its sliding stability.
