Description

Technical Field

[0001] The utility model relates to the technical field of moulds, in particular to a two-color mould. Background Art

[0025] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the present invention will be further elaborated.

[0026] First, it will be combined with Figures 1 to 4 Describe the two-color mold according to the embodiment of the present invention, which is used in an injection molding device and has a wide range of application scenarios.

[0027] As Figures 1 to 4 shown, the two-color mold of the embodiment of the present invention includes a first-shot shovel base 1, a slider seat 2 and a second-shot shovel base 3;

[0028] The slider seat 2 is provided with a first chute 21 and a pair of second chutes 22;

[0029] The first-shot shovel base 1 and the second-shot shovel base 3 can be connected to the slider seat 2 through the first chute 21;

[0030] A pair of second chutes 22 are arranged on both sides of the first chute 21;

[0031] A clamping assembly 4 is arranged in the second chute 22;

[0032] A first shooting shovel base 1 can be slidably connected to a clamping component 4;

[0033] On both sides of the front end of the second shooting shovel base 3, there are clamping parts, and the clamping parts can be clamped with the clamping component 4.

[0034] Furthermore, as Figures 1 to 3 shown, in this embodiment, the clamping component 4 includes: a clamping key 41, an elastic member 42 and a pressing plate 43;

[0035] The clamping key 41 is slidably connected to the corresponding second sliding groove 22;

[0036] One end of the elastic member 42 is connected to the pressing plate 43, and the other end is connected to the clamping key 41 for resetting the clamping key 41.

[0037] The pressing plate 43 is connected to the slider base 2.

[0038] Furthermore, as Figures 1 to 2 shown, in this embodiment, the elastic member 42 is a spring.

[0039] Furthermore, as Figure 1 shown, in this embodiment, a first limiting step 411 is provided on the clamping key 41, and a second limiting step 221 coupled with the first limiting step 411 is provided in the second sliding groove 22 to prevent the clamping key 41 from disengaging from the second sliding groove 22.

[0040] Furthermore, as Figure 1 、 4 shown, in this embodiment, a first limiting groove 23 corresponding to the pressing plate 43 is provided on the outer side of the slider base 2, the pressing plate 43 is arranged in the first limiting groove 23, and the first limiting groove 23 is communicated with the second sliding groove 22, which avoids the pressing plate 43 protruding from the slider base 2 and is not likely to cause interference on the external structure.

[0041] Furthermore, as Figure 1 shown, in this embodiment, the pressing plate 43 is fixedly connected to the slider base 2 by screws, so that the pressing plate 43 is detachable.

[0042] Furthermore, as Figures 2 to 3 shown, in this embodiment, a chamfer is provided on one side of the clamping key 41 relative to the second shooting shovel base 3, which is convenient for the first shooting shovel base 1 and the second shooting shovel base 3 to enter the first sliding groove 21.

[0043] Working principle: During the first injection molding (i.e., the first shot), the front end of the first-shot shovel base 1 enters the first chute 21 until it pushes the slider seat 2 to move inward. The slider seat 2 pushes the slider 5 into a closed state, and the key 41 in the second chute 22 is compressed. After the first injection molding is completed, the first-shot shovel base 1 exits the first chute 21 (since the first-shot shovel base 1 is not provided with a clamping portion, when the first-shot shovel base 1 retracts, it does not drive the slider seat 2 to move), and the key 41 resets. The driving mechanism on the injection molding machine drives the slider seat 2, the slider 5, and the related fixtures to rotate 180°. The front end of the second-shot shovel base 3 enters the first chute 21 until it pushes the slider seat 2 to move inward. The slider seat 2 pushes the slider 5 into a closed state, and the key 41 in the second chute 22 is first compressed and then partially resets. After the second injection molding is completed, the second-shot shovel base 3 retracts outward, and the clamping portion is clamped with the corresponding key 41, and at the same time drives the slider seat 2 and the slider 5 to retract outward until the slider 5 is disengaged from the product position is completed.

[0044] Above, with reference to Figures 1 to 4 The two-color mold according to the embodiment of the present invention is described, making the rear mold slider structure simple and occupying less space; no additional oil cylinders and actions are required, the actions are coherent and time-saving; the structure is stable and reliable, and the cost is saved.

[0045] It should be noted that in this specification, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, the element defined by the statement "comprising..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0046] Although the content of the present invention has been described in detail through the above preferred embodiments, it should be recognized that the above description should not be considered as a limitation of the present invention. After those skilled in the art have read the above content, various modifications and alternatives to the present invention will be obvious. Therefore, the protection scope of the present invention should be defined by the appended claims.
