Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a single-injection dual-mold flexible conversion injection molding mold. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors and shapes, shapes that can be simple or complex, sizes that can be large or small, precise product dimensions, easy product updates and replacements, and the ability to produce complex-shaped parts. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products.

[0003] In existing technologies, injection molding requires a mold to shape plastic material, which is then injected into the mold cavity by an injection mechanism. Generally, one mold is matched with one injection mechanism. However, using one injection mechanism with one mold is wasteful and does not improve the efficiency of injection molding. Therefore, we propose a single-injection dual-mold flexible conversion injection molding mold. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Injection molding requires a mold to shape plastic material, which is then injected into the mold cavity by an injection mechanism. Generally, a mold is paired with an injection mechanism, but using one injection mechanism with one mold is wasteful and does not improve the efficiency of injection molding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A single-injection dual-mold flexible conversion injection molding mold includes a base plate, an injection mechanism is fixedly connected to the front side near the back side of the top of the base plate, and a molding mechanism is fixedly connected to the top of the base plate near the back side.

[0007] The injection molding mechanism includes a base, an injection tube connected to the front of the base and connected to an external plastic injection mechanism, a distribution pipe connected to both sides of the base and connected to the injection tube, a telescopic hose fixedly connected to the bottom of the side of the distribution pipe away from the base, a support pipe fixedly connected inside the telescopic hose and inside the distribution pipe, a feeding pipe connected to the bottom of the telescopic hose, and a conversion component connected to the end of the feeding pipe away from the telescopic hose.

[0008] The molding mechanism includes a first molding die and a second molding die, with the second molding die located on the right side of the first molding die.

[0009] As a preferred embodiment of this utility model, the conversion component includes a feed pipe, and an electrically controlled valve is sleeved around the feed pipe, the electrically controlled valve being able to control the opening and closing of the feed pipe.

[0010] The technical effect of adopting the above-mentioned further solution is that, by setting the conversion component, the electric control valve can effectively control the opening and closing of the feed pipe. In this way, by controlling the opening and closing of the feed pipe, the injection control of the first molding mold and the second molding mold can be completed, thereby effectively saving costs and increasing efficiency.

[0011] As a preferred embodiment of the present invention, the first molding mold includes a first base plate, a first lower template is fixedly connected to the top of the first base plate, and a first molding cavity is formed at the center of the top of the first lower template.

[0012] As a preferred embodiment of the present invention, the first molding mold further includes a first upper template, the top of which is provided with a first injection port, the first injection port being connected to the first molding cavity and the first injection port being connected to the conversion component.

[0013] As a preferred embodiment of the present invention, the second molding die includes a second base plate, a second lower template is fixedly connected to the top of the second base plate, and a second molding cavity is formed at the center of the top of the second lower template.

[0014] As a preferred embodiment of this utility model, the second molding mold further includes a second upper template, the top of which is provided with a second injection port, which is connected to the second molding cavity and the conversion component.

[0015] The technical effect of adopting the above-mentioned further solution is that, by setting the second upper mold, the second upper mold can cooperate with the second lower mold, thereby completing the molding of the injection molded part through cooperation.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, the injection molding mechanism and the molding mechanism are designed to allow the injection molding mechanism to be effectively connected to the outside via the injection tube, thus facilitating the supply of injection molding materials. The diversion tube effectively diverts the incoming injection molding materials, allowing them to enter the first molding mold and the second molding mold respectively. The conversion component allows the injection molding materials to be controlled to enter either the first or the second molding mold, thus enabling one injection mechanism to be used with two molds, avoiding waste and effectively increasing the efficiency of injection molding.

[0026] Example 1

[0027] like Figure 1-3 As shown, this utility model provides a technical solution: a single-injection dual-mold flexible conversion injection molding mold, including a base plate 1. An injection molding mechanism 2 is fixedly connected to the front side of the top near the back side of the base plate 1, and a molding mechanism 3 is fixedly connected to the top near the back side of the base plate 1. The injection molding mechanism 2 includes a base 21. An injection tube 22 is connected to the front side of the base 21 and is connected to an external plastic injection mechanism. Diversion pipes 23 are connected to both sides of the base 21 and are connected to the injection tube 22. The bottom side of the diversion pipe 23 away from the base 21 is... A telescopic hose 24 is fixedly connected to the part. A support pipe 25 is fixedly connected inside the telescopic hose 24 and inside the diversion pipe 23. The support pipe 25 can slide up and down inside the feeding pipe 26 to facilitate the separation of the first upper mold plate 314 and the second upper mold plate 324. The bottom of the telescopic hose 24 is connected to the feeding pipe 26. The end of the feeding pipe 26 away from the telescopic hose 24 is connected to the conversion component 27. The molding mechanism 3 includes a first molding mold 31 and a second molding mold 32. The second molding mold 32 is located on the right side of the first molding mold 31.

[0028] Example 2

[0029] like Figure 1-3 As shown, the conversion component 27 includes a feed pipe 271, and an electric control valve 272 is sleeved around the feed pipe 271. The electric control valve 272 can control the opening and closing of the feed pipe 271 and can effectively control the direction of the injection molding material.

[0030] The first molding die 31 includes a first base plate 311, a first lower template 312 is fixedly connected to the top of the first base plate 311, and a first molding cavity 313 is provided at the center of the top of the first lower template 312, which facilitates the molding of injection molded parts.

[0031] The first molding die 31 also includes a first upper template 314. The top of the first upper template 314 is provided with a first injection port 315. The first injection port 315 is connected to the first molding cavity 313 and is also connected to the conversion component 27. The first upper template 314 is engaged with the first lower template 312 through a guide post.

[0032] The second forming mold 32 includes a second base plate 321, a second lower template 322 is fixedly connected to the top of the second base plate 321, and a second forming cavity 323 is opened at the top center of the second lower template 322.

[0033] The second molding die 32 also includes a second upper template 324. The top of the second upper template 324 is provided with a second injection port 325. The second injection port 325 is connected to the second molding cavity 323 and is also connected to the conversion component 27. The material can be easily injected into the interior of the second molding cavity 323 through the second injection port 325.

[0034] The working process of this utility model is as follows: When using a single-injection dual-mold flexible conversion injection molding die for injection molding, firstly, when the external injection plastic feeding mechanism delivers injection plastic, the injection plastic enters the injection tube 22. After entering the injection tube 22, it continues to be conveyed along the diversion tube 23 to the support tube 25, and then further conveyed to the feeding tube 26. At this time, when it is necessary to inject plastic into the first molding die 31, it is only necessary to close the electric control valve 272 on the second molding die 32 and open the electric control valve 272 on the first molding die 31. After the electric control valve 272 is opened, the injection plastic will flow through the first injection port. 315 enters the first molding cavity 313. After the first molding cavity 313 is injected, during cooling, the electric control valve 272 on the top of the second molding mold 32 can be opened. After opening, the injection plastic enters the second molding cavity 323 through the second injection port 325. When the second molding mold 32 is being injected, the first molding cavity 313 has cooled down, and the injection molded part can be taken out at this time. In this way, when the second molding cavity 323 is cooled down, the first molding mold 31 can continue to be injected. This utility model, through its design, can effectively avoid waste by using a single injection mechanism with dual molds, while improving the efficiency of injection molding.
