Description

Technical Field

[0001] This utility model belongs to the field of molds, specifically relating to a two-color mold with a secondary ejection structure. Background Technology

[0002] With the continuous progress of society and the continuous development of technology, molds have become the most important production tool. Due to the diversification of products on the market, traditional single injection molds can no longer meet the production needs of diversified products. Therefore, two-color molds are becoming increasingly popular in the market. This process can make the product look more beautiful and make it easier to change colors without spraying.

[0003] Currently, two-color molds on the market typically involve placing the product, after it has been injection molded in a single color, into another mold and performing a second injection molding to achieve a two-color molding effect. However, in actual use, due to the small distance between the upper and lower mold plates, and the fact that the lower mold plate is usually integrated with the main body of the mold, the limited operating space makes it difficult for workers to handle the products, thus affecting production efficiency. Therefore, a two-color mold with a secondary ejection structure is proposed to solve the above-mentioned problems. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-3 The two-color mold with a secondary ejection structure in this embodiment can improve the efficiency and convenience of use by increasing the hand operation space and reducing the operation path when the operator picks up and puts down the product 7.

[0022] Specifically, it includes mold base 1;

[0023] Mold body 2, positioned above mold body 2;

[0024] The pusher 3 is set in the mold base 1 and passes through the mold body 2;

[0025] The mold clamping component 4 is mounted on the pusher component 3. The mold clamping component 4 includes two second top plates 41, which are symmetrically arranged and the lower second top plate 41 is located at the top of the pusher component 3. Two hydraulic cylinders 42 are located below the lower second top plate 41. The push shaft of the hydraulic cylinder 42 passes through the lower second top plate 41 and is connected to the bottom of the upper second top plate 41. The two second top plates 41 can be separated by the hydraulic cylinders 42.

[0026] The pusher 3 can push the two second top plates 41 upwards and out of the interior of the mold body 2.

[0027] In this embodiment, when product 7 needs to be placed in for secondary injection molding, the pusher 3 first pushes the two second top plates 41 upwards out of the mold body 2. After reaching the limit height, the cylinder 42 pushes the upper second top plate 41, causing the two second top plates 41 to separate, completing the secondary ejection process. After the two second top plates 41 move upwards and unfold, the product 7, which has been injection molded in monochrome, can be placed into the second top plates 41 respectively. Then, the two second top plates 41 close under the action of the cylinder 42. At the same time, the pusher 3 pulls the mold closing part 4 into the mold body 2, and after completing the secondary injection molding, the top of the mold closing part 4 is opened again. The second top plate 41 is separated to allow for the removal of the final finished product. Since the second top plate 41 is raised and there are no obstructions around it, it is convenient for workers to pick up and put down the product 7 that has been completed with monochrome injection molding. At the same time, the design of raising the height of the second top plate 41 can also be closer to the user's height, thereby reducing the operation path and improving the efficiency and convenience of picking up and putting down the product 7. Moreover, the two second top plates 41 are designed to be ejected twice by hydraulic cylinders 42. Compared with the existing technology, the separation distance of the two second top plates 41 can be increased, thereby increasing the user's hand operation space when picking up and putting down the product 7, further improving the efficiency and convenience of use.

[0028] Specifically, refer to Figure 2 The pusher 3 includes a first top plate 31 slidably disposed inside the mold base 1; four slide rods 32 disposed on the first top plate 31 and slidingly passing through the mold base 1 and the mold body 2; springs 33 sleeved on the outer wall of the slide rods 32, with the two ends of the springs 33 respectively connected to the first top plate 31 and the mold base 1; and two push rods 34 respectively disposed on the first top plate 31, with the top ends of the push rods 34 slidingly passing through the mold base 1 and the mold body 2 in sequence and connecting to the bottom of the second top plate 41 below.

[0029] In this embodiment, when it is necessary to eject the two second top plates 41 from the mold body 2, under the action of external hydraulic, pneumatic or electric push cylinders, the first top plate 31 moves upward and pushes the second top plates 41 out of the mold body 2 through the push rod 34, while simultaneously squeezing the spring 33 to complete the ejection process of the two second top plates 41. When the two second top plates 41 are pulled back into the mold body 2, the first top plate 31 moves downward under the action of external hydraulic, pneumatic or electric push cylinders and pulls the two second top plates 41 back into the mold body 2. During this process, the spring 33 can provide auxiliary pushing force to the first top plate 31 through its rebound force to complete the return process of the two second top plates 41.

[0030] Specifically, refer to Figure 2 The mold assembly 4 includes several injection molds 43 disposed on the front side of the two second top plates 41. The injection molds 43 have mold grooves 44 inside; the top of the upper injection mold 43 has injection holes 45.

[0031] In this embodiment, each injection mold 43 can respectively receive the product 7 after single-color injection molding and provide an injection template for secondary injection molding material. When the two second top plates 41 are closed and taken into the mold body 2, other colored injection molding materials can be injected into the injection hole 45. When the injection molding material is fused with the product 7 and cooled, the two-color molding process of the product 7 can be realized.

[0032] Specifically, refer to Figure 1-2 The bottom wall of the inner cavity of the mold base 1 is provided with several limiting rods 5. The limiting rods 5 slide through the first top plate 31 and are used to provide limiting guidance for the first top plate 31.

[0033] In this embodiment, during the up-and-down movement of the first top plate 31, the limiting rod 5 slides in the first top plate 31. The sliding cooperation between the two can provide limiting guidance for the first top plate 31 during movement and improve the stability during movement.

[0034] Specifically, refer to Figure 1-3 Two limiting rods 6 are provided at the top of the second top plate 41 below. The limiting rods 6 slide through the second top plate 41 above and are used to provide limiting guidance for the second top plate 41.

[0035] In this embodiment, when the two second top plates 41 separate, the upper second top plate 41 slides on the outer wall of the limiting rod 6. The sliding cooperation between the two can provide the second top plate 41 with limiting and guiding capabilities and improve the stability during movement. At the same time, the two second top plates 41 can maintain a relative state before and after displacement.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
