Description

Technical Field

[0001] The utility model relates to an integrated automatic water-cutting injection molding device, in particular to an integrated automatic water-cutting injection molding device, belonging to the technical field of injection molding equipment. Background Art

[0002] Most of the current plastics are made by injection molding. During the injection molding process, a glue inlet needs to be opened on the mold. The glue inlet is connected to the mold cavity to inject molten plastic material into the mold cavity. The molten plastic material enters the mold cavity to form a product. The corresponding inlet of the molten plastic material on the product is the sprue. In order to ensure the efficiency of injection molding and save production costs, multiple cavities are generally designed on the injection mold and multiple glue inlets are used. This makes the plastic parts of the injection molded products have sprues after the injection molding is completed. After the product is formed, the mold needs to be opened first to take out the product. At this time, the product is connected with the sprue, and then the product and the sprue are fixed on a special fixture to cut off the material head. The above steps need to be completed manually. Due to manual operation, there are differences between individuals, resulting in a certain proportion of defective products.

[0003] Most of the current molds are split molds, which require removing the upper mold and then taking out the product inside the lower mold. There are many steps. At the same time, after the water outlet on the plastic part is cut off, the remaining parts after cutting are not easy to take out.

[0004] Therefore, there is an urgent need for an integrated automatic water-cutting injection molding device to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide an injection molding device with integrated automatic water-cutting opening, which is an integrated device. After the later injection molding is completed, it can automatically rise, and at the same time, it will automatically cut the water-cutting opening and lift up the product in the mold cavity, thus eliminating many operating steps and improving the convenience of taking out parts. At the same time, the residual parts inside the injection molding channel will automatically slide out, making it easy to clean the residual parts.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include: an integrated automatic water-cutting injection molding device, including a lower mold and an upper mold, the lower mold and the upper mold are connected by a plurality of electric telescopic rods; a mold cavity is provided in the lower mold, a lifting base is slidably provided in the mold cavity, cutters are slidably provided on both sides of the mold cavity, connecting rods are provided on both sides of the upper mold, a through cavity is provided below the lower mold, a support plate is provided below between the two connecting rods, the cutter is connected to the support plate below through a support rod, and a second support rod is provided on the lower end face of the lifting base; injection ports are provided on both sides of the upper mold, and an electric telescopic plate is provided on the lower end face of the upper mold.

[0007] Preferably, a placement cavity is opened at each corner of the upper end surface of the lower mold, and the electric telescopic rod is arranged in the placement cavity, and the electric telescopic rod is a segmented electric telescopic rod.

[0008] Preferably, the connecting rods on both sides are arranged vertically downward, and sliding grooves for the cutting knife to slide are provided on both sides of the mold cavity, and the distance between the sliding grooves and the mold cavity does not exceed 5 mm.

[0009] Preferably, the overall length of the cutter and the support rod is greater than the length of the second support rod.

[0010] Preferably, a supporting step for supporting the lifting base is provided below the inner wall of the mold cavity.

[0011] Preferably, both sides of the upper mold are chamfered surface structures, and an injection channel inclined toward the mold cavity is opened on the chamfered surface structure, and the opening of the lower end surface of the injection channel is close to the inner wall of the mold cavity.

[0012] Preferably, a placement groove is provided on the lower end surface of the upper mold, a second electric telescopic rod is arranged in the placement groove, the lower end surface of the second electric telescopic rod is connected to the electric telescopic plate, and a hidden groove for hiding the electric telescopic plate is provided on the lower end surface of the upper mold.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. When the product is demolding, the upper mold is driven to rise by extending the electric telescopic rod. During the rising process of the upper mold, the second electric telescopic rod is extended to first support the product that has been injection molded, and then the cutter is driven to rise through the connecting rod support plate, so that the cutter first contacts the successfully injected product and cuts off the water cut. As the upper mold continues to rise, the support plate will contact the second support rod to realize the rise of the jacking base, and at the same time, the second electric telescopic rod contracts to drive the electric telescopic plate to contract into the hidden groove, thereby ejecting the mold that has been formed in the mold cavity, and then taking it out, which saves a lot of operating steps and improves the convenience of taking out. The inclined injection channel ensures that when the upper mold is separated from the lower mold in the later stage, the residual parts inside the injection channel will automatically slide off, which is convenient for cleaning the residual parts in the later stage.

DETAILED DESCRIPTION

[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figure 1-Figure 5 As shown, the integrated automatic water-cutting injection molding device provided in this embodiment includes a lower mold 1 and an upper mold 2, and the lower mold 1 and the upper mold 2 are connected by a plurality of electric telescopic rods 3; a placement cavity 13 is opened at each corner of the upper end surface of the lower mold 1, and the electric telescopic rod 3 is arranged in the placement cavity 13, and the electric telescopic rod 3 is a segmented electric telescopic rod, and the multi-stage electric telescopic rod 3 is placed inside the placement cavity 13, so that it can completely enter the placement cavity 13 when it is contracted, to ensure the fit between the upper mold 2 and the lower mold 1 when they are fitted, and the multi-stage setting can ensure the rising height of the upper mold 2, which is convenient for taking materials;

[0024] A mold cavity 4 is provided in the lower mold 1, a lifting base 5 is slidably provided in the mold cavity 4, cutters 6 are slidably provided on both sides of the mold cavity 4, connecting rods 7 are provided on both sides of the upper mold 2, and the connecting rods 7 on both sides are vertically downwardly provided, and slide grooves 14 for sliding of the cutter 6 are provided on both sides of the mold cavity 4, and the distance between the slide groove 14 and the mold cavity 4 does not exceed 5 mm, so as to ensure a good cutting and smoothing effect; a supporting step 15 for supporting the lifting base 5 is provided below the inner wall of the mold cavity 4, so as to ensure that the lifting base 5 will not fall into the through cavity 21;

[0025] A through cavity 21 is provided at the bottom of the lower mold 1, a support plate 8 is provided below the two connecting rods 7, the bottom of the cutter 6 is connected to the support plate 8 through a support rod 9, and a second support rod 10 is provided at the lower end surface of the jacking base 5; the overall length of the cutter 6 and the support rod 9 is greater than the length of the second support rod 10, so that when the upper mold 2 is rising and the cutter 6 is driven to rise by the connecting rod 7 support plate 8, the cutter 6 will first contact with the successfully injected product and cut off the water cutout. As the upper mold 2 continues to rise, the support plate 8 will contact with the second support rod 10, so as to realize the rising of the jacking base 5, thereby ejecting the mold that has been formed in the mold cavity 4;

[0026] Injection ports 11 are provided on both sides of the upper mold 2, wherein both sides of the upper mold 2 are chamfered surface structures 16, and an injection channel 17 inclined toward the mold cavity 4 is provided on the chamfered surface structure 16, and the opening of the lower end surface of the injection channel 17 is close to the inner wall of the mold cavity 4, and the injection channel 17 is used for drainage injection into the mold cavity 4. The inclined setting ensures that when the upper mold 2 is separated from the lower mold 1 later, the residual parts inside the injection channel 17 will automatically slide down, which is convenient for cleaning the residual parts later;

[0027] The lower end surface of the upper mold 2 is provided with an electric telescopic plate 12, and the lower end surface of the upper mold 2 is provided with a placement groove 18, and a second electric telescopic rod 19 is provided in the placement groove 18. The lower end surface of the second electric telescopic rod 19 is connected to the electric telescopic plate 12, and the lower end surface of the upper mold 2 is provided with a hidden groove 20 for hiding the electric telescopic plate 12. When the upper mold 2 and the lower mold 1 are fitted, the electric telescopic plate 12 is in a state of being retracted to the inside of the hidden groove 20 and flush with the lower end surface of the upper mold 2. When the upper mold 2 rises, the second electric telescopic rod 19 is extended to first support the injection molded product to ensure that the cutter 6 will not lift up the entire product when cutting at the cutting water outlet position when it rises, thereby affecting the cutting effect.

[0028] like Figure 1-Figure 5 As shown, the principle of the integrated automatic water-cutting injection molding device provided in this embodiment is as follows: when in use, the upper mold 1 and the lower mold 2 are in a tightly fitted state, and injection molding is performed into the mold cavity 4 through the injection molding channels 17 on both sides and cooled. When demolding is performed later, the upper mold 2 is driven to rise by extending the electric telescopic rod 3. During the rising process of the upper mold 2, the second electric telescopic rod 19 is extended to first support the injection-molded product, and then the connecting rod 7 support plate 8 drives the cutter 6 to rise, so that the cutter 6 first contacts the successfully injected product and cuts off most of the water-cutting port. As the upper mold 2 continues to rise, the support plate 8 will be connected with the second support rod 10. The lifting base 5 is touched to realize the rising of the jacking base 5, and at the same time, the second electric telescopic rod 19 contracts to drive the electric telescopic plate 12 to contract into the hidden groove 20, so as to eject the mold that has been formed in the mold cavity 4, and then take it out. After taking it out, it can be slightly polished. The inclined injection channel 17 ensures that when the upper mold 2 is separated from the lower mold 1 in the later stage, the residual parts inside the injection channel 17 will automatically slide down, which is convenient for cleaning the residual parts in the later stage. It should be noted that the outside of the mold device will be equipped with a remote control for controlling the electric telescopic rod 3 and the second electric telescopic rod 19. Since the use of a remote control to control the extension or contraction of the electric telescopic rod is a mature existing technology, it will not be explained in detail.
