Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold slider gate ejection structure. Background Technology

[0002] In the automotive lighting industry, as the appearance of headlights becomes increasingly complex, conventional methods cannot meet the requirements of gate design and mold structure. Existing technical problems are mainly due to the limited gate location. For example, conventional gate design can only be set in specific positions, but due to the complexity of the product appearance, these conventional positions cannot be used, which makes it impossible to reasonably set the gate on the mold and affects the molding quality of the product. To address this, the inventors set the gate on the slider to meet the requirements of the complex appearance of the product. Based on this, a slider gate ejection structure was designed. After injection molding is completed, the product on the slider is ejected by this ejection mechanism. Utility Model Content

[0003] The purpose of this invention is to provide a mold slider gate ejection structure to solve the above-mentioned technical problems.

[0004] This utility model provides the following technical solution:

[0005] A mold slider gate ejection structure includes: a lower mold part, a slider disposed on the upper end of the lower mold part, and a gate is also provided on the slider;

[0006] The slider is provided with an ejection mechanism for ejecting the product, and an ejector plate is provided directly below the lower mold part, and a first ejector pin is fixedly provided on the ejector plate.

[0007] The slider slides along the upper end of the lower mold until the first ejector pin aligns with the ejection mechanism, so that the ejection mechanism is driven forward by the first ejector pin to eject the product inside the slider.

[0008] Furthermore, the lower mold part is also provided with a lower mold cavity, and the lower mold cavity is also provided with a main gate.

[0009] Furthermore, a cold runner is provided on the slider, and the gate is provided through one end of the cold runner.

[0010] Furthermore, the gate is angled, and the outlet of the gate is biased towards the lower mold cavity.

[0011] Furthermore, the ejection mechanism includes an ejector guide sleeve that passes through the slider, and a second ejector pin is slidably disposed on the inner side of the ejector guide sleeve.

[0012] Furthermore, the upper opening of the ejector pin guide sleeve is in communication with the cold flow channel.

[0013] Furthermore, the slider is moved laterally so that the first pin is aligned with the second pin.

[0014] Furthermore, a spring is provided between the second ejector pin and the ejector pin guide sleeve, and the spring drives the second ejector pin to reset.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, by setting an oblique gate on the slider, the traditional gate position design is broken through, which can be used to mold products with complex appearances. Based on this design, an ejection mechanism is also set in the slider. The ejection mechanism includes a second ejector pin. After the slider is moved to a designated location, the first ejector pin is driven by the ejector plate to align with the second ejector pin. The second ejector pin ejects the product in the slider to improve the molding quality of the product. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5As shown, this utility model provides a technical solution: a mold slider gate ejection structure, including a lower mold part 100, a lower mold cavity 110 for molding, and a slider 101 slidably disposed on the upper end of the lower mold part 100. The slider 101 is located on the side of the lower mold cavity 110. An independent ejection mechanism is also disposed along the inside of the slider 101. An ejector plate 200 is also disposed directly below the lower mold part 100. At least two sets of first ejector pins 210 are fixedly disposed on the ejector plate 200. The ejector plate 200 can be driven by the ejector rod part of the injection molding machine to move the two sets of first ejector pins 210 on the ejector plate 200. The first ejector pins 210 correspond to the independent ejection mechanism in the slider 101.

[0025] Furthermore, the ejection mechanism includes a second ejector pin 101-4 movably disposed in the slider 101. An ejector pin guide sleeve 101-2 is also provided inside the slider 101 to accommodate and slide the second ejector pin 101-4. The ejector pin guide sleeve 101-2 is a through-type design. Figure 2 As shown, the slider 101 is also provided with a cold runner 101-1 for raw material flow, and the upper opening of the ejector guide sleeve 101-2 is located inside the cold runner 101-1. A gate 101-3 is also obliquely provided along the end of the cold runner 101-1 near the lower mold cavity 110. The outlet of the gate 101-3 is biased towards the molding cavity of the lower mold cavity 110, and a main gate 110-1 is provided on the lower mold cavity 110.

[0026] In operation, the injection port of the injection molding machine first fills the product body through the main gate 110-1, while the gate 101-3 located on the slider 101 enters the material slightly later to avoid the slider 101 shifting due to lateral pressure. The main gate 110-1 fills the product body, while gate 101-3 supplements the melt flow in the lateral area to prevent incomplete filling. When the injection port injects the raw material along the cold runner 101-1, the raw material then enters the molding cavity obliquely along gate 101-3. Figure 4-5As shown, after injection molding is completed, the cold runner 101-1 remains on the slider 101 and moves together with the slider 101. After injection molding is completed, the slider 101 drives the cold runner 101-1 to move backward by a distance of 32mm. The ejection mechanism set in the slider 101 also moves backward by the same distance as the slider 101, so that the ejection mechanism is aligned with the first ejector pin 210 on the ejector plate 200. This means that the second ejector pin 101-4 in the ejection mechanism is aligned with the first ejector pin 210. At this time, the ejector pin plate 200 is driven to move by the ejector rod of the injection molding machine. The first ejector pin 210 moves accordingly. The upper end of the first ejector pin 210 is aligned with the lower end of the second ejector pin 101-4 and ejects it from the ejector guide sleeve 101-2. The upper end of the second ejector pin 101-4 ejects the cooling material head located in the cold runner 101-1 out of the lower mold part 100. After the complete ejection is completed, the next action is performed.

[0027] Furthermore, such as Figure 4 As shown, a spring 101-5 is also provided between the ejector guide sleeve 101-2 and the second ejector 101-4. After ejection, the spring 101-5 drives the second ejector 101-4 to retract and reset in the ejector guide sleeve 101-2. The first ejector 210 retracts and resets along with the ejector plate 200. The slider 101 moves to the left and drives the second ejector 101-4 to reset along the horizontal position, offset from the first ejector 210. This cycle repeats to achieve repeated operation.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
