Description

Technical Field

[0001] This utility model belongs to the technical field of plastic molds, specifically relating to a split-type upward-moving inclined ejector. Background Technology

[0002] In the process of plastic injection molding, after the product is injection molded, external force needs to be applied to eject it from the mold. When the molded product has an undercut circumferential structure and stepped bosses, traditional molding molds, with their limited internal space, make it difficult to demold the product using conventional angled ejectors. Therefore, to meet the space constraints within the mold and to facilitate convenient demolding of products with undercut circumferential structures and stepped bosses after molding, this invention discloses a split-type upward-moving angled ejector. Utility Model Content

[0003] This utility model discloses a split-type upward-moving inclined ejector. Through the separate structure of the first and second inclined ejectors, the movement of the first inclined ejector drives the second inclined ejector to move in tandem, thereby enabling rapid demolding of molded products with inverted peripheral structures and stepped bosses within the narrow space inside the mold.

[0004] This utility model is achieved through the following technical solution:

[0005] A split-type upward-sloping top includes an insert. A first sloping top and a second sloping top are slidably disposed on both sides of the insert. The first sloping top on the same side slides in the opposite direction to the second sloping top along the inclination of the insert. The bottom of the second sloping top is slidably connected to the first sloping top in the horizontal direction. A pin is slidably engaged at the bottom of the first sloping top in the horizontal direction. The tops of the first sloping top and the tops of the second sloping top are provided with stepped semi-grooves that can be joined together to form a frustum-shaped concave hole.

[0006] When the top force is applied to the first inclined top, the first inclined top slides upward along the first inclined direction under the limiting and guiding action of the insert. At the same time as the first inclined top slides upward, it drives the second inclined top to slide upward along the second inclined direction. This causes the stepped half-groove at the top of the first inclined top and the stepped half-groove at the top of the second inclined top to move away from each other. This allows the stepped half-groove to move away from each other while lifting the formed product, and at the same time, the stepped half-groove can be moved away from each other to release the stepped frustum on the formed product, so that the product can be quickly demolded.

[0007] When the top pin applies a downward force to the first inclined pin, the first inclined pin slides down along the first inclined direction under the limiting and guiding action of the insert. At the same time as the first inclined pin slides down, it drives the second inclined pin to slide down along the second inclined direction, thereby causing the stepped half-groove at the top of the first inclined pin and the stepped half-groove at the top of the second inclined pin to move closer to each other, so as to realize the reset of the inclined pin.

[0008] To better realize this utility model, the insert is further provided with a guide boss in the middle, and inclined dovetail slides are provided on the left and right sides of the guide boss. A dovetail groove is provided on one side of the second inclined top, and the dovetail slides and the dovetail groove are slidably connected.

[0009] To better realize this utility model, the insert is further provided with inclined sliding grooves on the left and right sides, and an inclined slider is provided on one side of the first inclined top to slide in cooperation with the inclined sliding groove. The inclination direction of the inclined sliding groove is opposite to the inclination direction of the dovetail slide.

[0010] To better realize this utility model, a horizontal sliding groove is further provided between the upper and lower ends of the first inclined top, and a horizontal slider is provided at the bottom end of the second inclined top to slide and connect with the horizontal sliding groove in a horizontal direction.

[0011] To better realize this utility model, the bottom of the first inclined top is provided with a horizontal T-shaped groove in the horizontal direction, and the top of the pin is provided with a T-shaped slider that is slidably connected to the horizontal T-shaped groove in the horizontal direction and engaged in the vertical direction.

[0012] To better realize this utility model, the top of the first inclined top is provided with a first stepped half-groove, and the top of the second inclined top is provided with a second stepped half-groove. The first stepped half-groove and the second stepped half-groove are joined together to form a frustum-shaped concave hole.

[0013] To better realize this utility model, the top of the first inclined top and the top of the second inclined top are further provided with positioning grooves or positioning protrusions.

[0014] To better realize this utility model, the top of the insert is provided with at least one positioning boss.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] This invention enables rapid demolding of products by simultaneously lifting and disengaging the first and second inclined ejectors in the opposite direction, even in situations where the internal space of the mold is relatively narrow and limited. It achieves the functions of simultaneously lowering and reassembling the first and second inclined ejectors to reposition the product, thus adapting to narrow demolding spaces and enabling rapid demolding of products with undercut circumferential structures and stepped bosses.

Detailed Implementation

[0026] Example 1:

[0027] This embodiment features a split-type upward-sloping roof, such as... Figure 1 , Figure 2As shown, the device includes an insert 1. Both sides of the insert 1 are provided with a first inclined top 100 and a second inclined top 200. The first inclined top 100 on the same side slides in the opposite direction to the second inclined top 200 along the inclined direction of the insert 1. The bottom of the second inclined top 200 is slidably connected to the first inclined top 100 in the horizontal direction. The bottom of the first inclined top 100 is slidably engaged with a pin 2 in the horizontal direction. The tops of the first inclined top 100 and the tops of the second inclined top 200 are provided with stepped semi-grooves that can be joined together to form a frustum-shaped concave hole.

[0028] like Figure 4 As shown, when ejector pin 2 applies an upward force, it drives the first inclined ejector 100 to slide upward along the first inclined direction. At this time, the first inclined ejectors 100 on the left and right sides move away from each other. While the first inclined ejector 100 slides upward along the first inclined direction, it simultaneously drives the second inclined ejector 200 to slide upward along the second inclined direction through the horizontal sliding fit structure. At this time, the second inclined ejector 200 moves away from the first inclined ejector 100, thereby enabling the first inclined ejector 100 and the second inclined ejector 200 to lift the molded product upward while simultaneously causing the stepped half-groove to move away from each other, thereby releasing the stepped frustum on the molded product for rapid demolding.

[0029] like Figure 3 As shown, when the ejector pin 2 applies a downward force, it causes the first inclined ejector 100 to slide downward along the first inclined direction. At this time, the first inclined ejectors 100 on the left and right sides move closer to each other. While the first inclined ejector 100 slides downward along the first inclined direction, it simultaneously causes the second inclined ejector 200 to slide downward along the second inclined direction through the horizontal sliding fit structure. At this time, the second inclined ejector 200 moves closer to the first inclined ejector 100, thereby causing the first inclined ejector 100 and the second inclined ejector 200 to return to their downward reset position. At the same time, the stepped half-grooves can be joined together to form a frustum-shaped concave hole.

[0030] Example 2:

[0031] This embodiment is a further optimization based on Embodiment 1, such as... Figures 3-6 As shown, the insert 1 has a guide boss 11 in the middle, and inclined dovetail slides 101 are provided on the left and right sides of the guide boss 11. A dovetail groove 201 is provided on one side of the second inclined top 200. The dovetail slides 101 and the dovetail grooves 201 are slidably connected. Inclined slide grooves 21 are provided at the left and right edges of the insert 1. An inclined slider 22 is provided on one side of the first inclined top 100 and is slidably connected to the inclined slide groove 21. The inclination direction of the inclined slide groove 21 is opposite to the inclination direction of the dovetail slide 101.

[0032] The guide boss 11 has an upright triangular structure, smaller at the top and larger at the bottom. Dovetail slides 101 on both sides of the guide boss 11 are arranged along the two edges of the upright triangular structure. A dovetail groove 201 is provided on the side of the second inclined top 200 closest to the guide boss 11. The dovetail groove 201 slides and engages with the dovetail slide 101, thus guiding the sliding of the second inclined top 200. When the dovetail groove 201 slides upwards along the dovetail slide 101, it causes the second inclined top 200 to move away from the first inclined top 100; when the dovetail groove 201 slides downwards along the dovetail slide 101, it causes the second inclined top 200 to move closer to the first inclined top 100. Through the engagement of the dovetail slide 101 and the dovetail groove 201, the interaction of the second inclined top 200 is guided, ensuring that the second inclined top 200 smoothly engages with or disengages from the first inclined top 100.

[0033] The other parts of this embodiment are the same as those in Embodiment 1, so they will not be described again.

[0034] Example 3:

[0035] This embodiment is a further optimization based on the above embodiment 1 or 2, such as... Figure 3 , Figure 4 , Figure 7 , Figure 8 As shown, a horizontal groove 31 is provided between the upper and lower ends of the first inclined top 100, and a horizontal slider 32 is provided at the bottom of the second inclined top 200, which is slidably connected to the horizontal groove 31 in the horizontal direction.

[0036] Specifically, a horizontal groove 31 is provided at the middle of the first inclined top 100, and a horizontal slider 32 extending into and slidably connected to the horizontal groove 31 is provided at the bottom of the second inclined top 200. When the first inclined top 100 tilts upward or downward, an upward or downward force is applied to the horizontal slider 32 through the horizontal groove 31, thereby driving the second inclined top 200 to tilt upward or downward. This achieves linkage between the first inclined top 100 and the second inclined top 200, ensuring that the first inclined top 100 and the second inclined top 200 move synchronously up and down, and also move away from or towards each other synchronously.

[0037] The other parts of this embodiment are the same as those in Embodiment 1 or 2 above, so they will not be described again.

[0038] Example 4:

[0039] This embodiment is a further optimization based on any one of embodiments 1-3 above, such as... Figure 7As shown, the bottom of the first inclined top 100 is provided with a horizontal T-shaped groove 41 in the horizontal direction, and the top of the pin 2 is provided with a T-shaped slider 42 that is slidably connected to the horizontal T-shaped groove 41 in the horizontal direction and engaged in the vertical direction.

[0040] The T-shaped slider 42 is slidably connected to the horizontal T-shaped groove 41 in the horizontal direction, and simultaneously engages with the horizontal T-shaped groove 41 in the vertical direction. When the ejector pin 2 is pushed up or pulled down, the first inclined ejector 100 can be moved up or down through the T-shaped slider 42.

[0041] The other parts of this embodiment are the same as any one of the embodiments 1-3 above, so they will not be described again.

[0042] Example 5:

[0043] This embodiment is a further optimization based on any one of embodiments 1-4 above, such as... Figure 7 and Figure 8 As shown, the top of the first inclined top 100 is provided with a first stepped half-groove 111, and the top of the second inclined top 200 is provided with a second stepped half-groove 222. The first stepped half-groove 111 and the second stepped half-groove 222 are joined together to form a frustum-shaped concave hole.

[0044] When the first inclined ejector 100 and the second inclined ejector 200 approach each other to the assembly state, the first stepped half-groove 111 and the second stepped half-groove 222 combine to form a frustum-shaped concave hole. This frustum-shaped concave hole cooperates with the stepped boss on one side of the molded product to position the molded product. When the first inclined ejector 100 and the second inclined ejector 200 move away from each other to the separation state, the first stepped half-groove 111 and the second stepped half-groove 222 separate to release the stepped boss of the molded product, facilitating easy demolding of the molded product.

[0045] Furthermore, both the top of the first inclined top 100 and the top of the second inclined top 200 are provided with positioning grooves or positioning protrusions. The positioning grooves are provided corresponding to the bottom end face edge of the formed product, and the positioning protrusions are provided corresponding to the grooves at the bottom of the formed product, thereby realizing rapid positioning of the formed product.

[0046] The other parts of this embodiment are the same as any one of the embodiments 1-4 above, so they will not be described again.

[0047] Example 6:

[0048] This embodiment is a further optimization based on any one of embodiments 1-5 above, such as... Figure 5 and Figure 6 As shown, the top of the insert 1 is provided with at least one positioning boss 12, which corresponds to the positioning hole on the formed product. The positioning boss 12 and the positioning hole cooperate to further position the formed product.

[0049] The other parts of this embodiment are the same as any one of the embodiments 1-5 above, so they will not be described again.

[0050] 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.
