Description

Technical Field

[0001] This utility model relates to the field of injection molds, specifically to a mold inclined ejection mechanism. Background Technology

[0002] The mold slant ejection mechanism is a structure commonly used in injection molds for demolding, which can achieve demolding of complex or difficult-to-demold products.

[0003] The existing mold angled ejection mechanism includes an ejector block, which consists of a head, a rod, and an elastic part. The elastic part is connected between the head and the rod. The existing ejector block is made entirely of spring steel (the head, rod, and elastic part are all made of spring steel and are connected as a single piece). Because the ejector block is irregularly shaped, it has the disadvantages of high processing difficulty, high material cost, and long manufacturing cycle. Moreover, if the ejector block is damaged, it is not convenient to repair and the entire ejector block must be scrapped, thereby increasing the production and use cost of the mold. Utility Model Content

[0004] The present invention aims to provide a mold inclined ejection mechanism to solve the current problem that the entire ejector block needs to be scrapped if it is damaged, thereby reducing the cost of using the ejector block.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mold inclined ejection mechanism, comprising an ejector block, the ejector block comprising an ejector block head, a spring steel sheet and an ejector rod, the spring steel sheet comprising a first end, a middle part and a second end, the middle part being integrally connected between the first end and the second end, the first end and the ejector block head being detachably connected, and the second end and the ejector rod being detachably connected.

[0006] The principle and advantages of this solution are as follows: the top block is mainly divided into three parts, including the top block head, the spring steel sheet, and the top rod, which are detachably connected in sequence. In this way, the top block head, the spring steel sheet, and the top rod can be processed separately, and then assembled after each part is processed. Compared with the existing technology of processing irregularly shaped top blocks as a whole, this greatly reduces the processing difficulty.

[0007] If any part of the top block, spring steel plate, or top rod is damaged during use, only the corresponding part needs to be replaced individually. This way, the entire top block does not need to be scrapped, reducing the cost of using the top block.

[0008] In addition, since the top block head, spring steel sheet and top rod are detachably connected, only the spring steel sheet needs to be made of spring steel, while the top rod does not need to be made of spring steel. Ordinary steel can be used for the top rod. Compared with the existing technology where the entire top block is made of spring steel, this greatly saves material costs and reduces the cost of using the top block.

[0009] Preferably, as an improvement, the top block head has a slot into which the first end is inserted. Thus, the inner wall of the slot limits the insertion of the first end, contributing to a stable connection between the first end and the top block head. Simultaneously, with the first end located in the slot, the slot accommodates the first end, preventing it from protruding from the top block head and avoiding the problem of the top block failing to properly fit on the mold if the first end protrudes.

[0010] Preferably, as an improvement, the slot opening is located on the side and bottom surface of the top block head; the thickness of the first end is greater than the thickness of the middle part. In this solution, the thickness of the first end is greater than the thickness of the middle part. The larger thickness of the first end makes it less likely for the spring steel sheet to break at the connection between the first end and the top block head, thus ensuring service life.

[0011] Meanwhile, in this design, the slot opening is located on the side and bottom of the top block head. This allows the slot to be machined from the outside of the top block head to match the first end, facilitating the machining of the slot on the top block head. On the other hand, it also facilitates the assembly of the first end and the slot. The first end can be easily assembled into the slot from the bottom and side of the top block head, avoiding the problem that the first end is too large and protruding, making it difficult to assemble into the slot.

[0012] Preferably, as an improvement, when the first end is inserted into the slot, the exposed surface of the first end in the slot is not higher than the side of the top block head.

[0013] Preferably, as an improvement, the exposed surface of the first end in the slot is flush with the side of the top block head.

[0014] Therefore, the exposed surface of the first end in the slot is not higher than the side of the top block head, or the exposed surface of the first end in the slot is flush with the side of the top block head. This design can prevent the exposed surface of the first end from protruding from the side of the top block head and affecting the normal use of the top block in the mold.

[0015] Preferably, as an improvement, the exposed surface of the first end is inclined. This inclined orientation of the exposed surface allows it to conform to the inclined outer surface of the top block head, thus preventing the exposed surface of the first end from protruding beyond the outer surface of the top block head, and also making the thickness of the first end gradually change.

[0016] Preferably, as an improvement, the exposed surface of the first end has a first countersunk hole, and a first connector for connecting the top block head and the first end is provided in the first countersunk hole. The first connector connects the top block head and the first end, and the first connector is located in the first countersunk hole and does not protrude from the top block head.

[0017] Preferably, as an improvement, the end of the push rod is provided with a clamping groove, into which the second end is inserted. Thus, the clamping groove clamps the second end, improving the connection stability between the second end and the push rod. Using this connection method, the second end is inserted into the clamping groove, resulting in a relatively small space occupied at the connection point between the push rod and the second end.

[0018] Preferably, as an improvement, the side of the push rod is provided with multiple second countersunk holes, and a second connector is provided in the second countersunk holes for connecting the push rod and the second end. The second connector realizes the connection between the push rod and the second end, and the second connector is located in the second countersunk holes and does not protrude from the push rod.

[0019] Preferably, as an improvement, the thickness of the second end is greater than the thickness of the middle part. In this design, the thickness of the second end is greater than the thickness of the middle part. The larger thickness of the second end makes it less likely for the spring steel sheet to break at the connection between the second end and the top rod, thus ensuring service life.

[0022] Figure 3 This is a schematic diagram of the spring steel sheet.

[0023] Figure 4 This is a schematic diagram of the top rod structure. Detailed Implementation

[0024] The following detailed description illustrates the specific implementation method:

[0025] The reference numerals in the accompanying drawings include: top block head 1, spring steel sheet 2, first end 21, middle part 22, second end 23, exposed surface 24, top rod 3, first connector 4, second connector 5, slot 6, clamping groove 7.

[0026] The basic implementation examples are as follows: Figures 1-4 As shown: A mold inclined ejection mechanism includes an ejector block, which comprises an ejector block head 1, a spring steel sheet 2, and an ejector rod 3. (Combined with...) Figure 3As shown, the spring steel sheet 2 in this embodiment includes a first end 21, a middle portion 22, and a second end 23. The middle portion 22 is integrally connected between the first end 21 and the second end 23. The spring steel sheet 2 is made of spring steel. The thickness of the first end 21 and the thickness of the second end 23 are both greater than the thickness of the middle portion 22. Specifically, the thickness of the spring steel sheet 2 gradually decreases from the first end 21 to the middle portion 22, and then gradually increases from the middle portion 22 to the second end 23. This results in a relatively small thickness for the middle portion 22, making it more prone to elastic bending deformation. The push rod 3 and the push block head 1 may not be made of spring steel; ordinary steel can be used instead.

[0027] In this embodiment, the first end 21 and the top block head 1 are detachably connected, and the second end 23 and the top rod 3 are detachably connected.

[0028] The specific detachable connection method between the first end 21 and the top block 1 is as follows: [Combination] Figure 2 As shown, the top block head 1 is provided with a slot 6, and the slot opening of the slot 6 is located at the top block head 1. Figure 2 On the right side and bottom surface. The first end 21 is inserted into the slot 6. The exposed surface 24 of the first end 21 in the slot 6 is not higher than the right side of the top block 1. Specifically, in this embodiment, the exposed surface 24 of the first end 21 in the slot 6 is flush with the right side of the top block 1. The exposed surface 24 of the first end 21 is inclined so as to adapt to the inclined right side of the top block 1. The exposed surface 24 of the first end 21 is flush with the inclined right side of the top block 1. At the same time, the inclined exposed surface 24 also makes the thickness of the first end 21 of the spring steel sheet 2 gradually change.

[0029] Combination Figure 1 As shown, the exposed surface 24 of the first end 21 is provided with a first countersunk hole. After the first end 21 is inserted into the slot 6, the top block 1 and the first end 21 are connected by inserting the first connector 4 (e.g., bolt or screw) into the first countersunk hole. Due to the setting of the slot 6, in this embodiment, the number of first connectors 4 can be set to one to fix the top block 1 and the spring steel plate 2, without the need to set extra first connectors 4. This structure is simple and is particularly suitable for the case of connecting the spring steel plate 2 with the small-volume top block 1.

[0030] In this embodiment, the specific connection method between the push rod 3 and the spring steel plate 2 is as follows: [Combination] Figure 4As shown, the end of the push rod 3 is provided with a clamping groove 7, and the left and right sides of the clamping groove 7 are connected. The second end 23 is inserted into the clamping groove 7 from the top of the push rod 3. The side of the push rod 3 is provided with two second countersunk holes, which are vertically distributed. After the second end 23 is inserted into the clamping groove 7, the push rod 3 and the second end 23 are connected by two second connectors 5 (such as screws or bolts) passing through the second countersunk holes respectively.

[0031] In this embodiment, the first end 21 is... Figure 3 The thickness of the top surface is 12-15mm, the thickness of the second end 23 is 5-7mm, and the minimum thickness of the middle part 22 is 3-4mm. The width of the slot 6 is 12mm. Figure 2 The distance from the bottom of the top block 1 to the inner side of the slot 6 relative to the bottom of the top block 1 is 20mm.
