[0002] Foam protective cover production molds are tools used to manufacture foam protective covers, which have the characteristics of high precision, durability and convenient operation. Foam protective cover molds play a key role in the production of foam protective covers. They can improve production efficiency and product quality and meet the specific needs of different products for protective covers. At the same time, they reduce mold costs and replacement frequency, bringing economic benefits to enterprises.

[0003] Most of the molds used for producing foam protective covers in the prior art are of fixed size and can only produce protective covers with fixed diameters. They lack adjustability when injection molding products with varying diameters. Therefore, in order to solve this problem, it is necessary to optimize the design of the product and propose an adjustable mold for producing foam protective covers. Utility Model Content

[0006] In a preferred embodiment, a transverse sliding groove adapted to the slide plate is provided in the track plate, and the slide plate is slidably installed in the transverse sliding groove.

[0007] In a preferred embodiment, a lead screw is threadedly connected to the slide plate, and a driving motor whose output shaft is fixed to the lead screw is fixedly mounted on the inner left side of the track plate.

[0008] In a preferred embodiment, the plurality of sets of jacket membrane plates are sequentially and tightly nested from the inside to the outside, and the left ends of the plurality of sets of jacket membrane plates are initially aligned.

[0009] In a preferred embodiment, the injection hole is located at the lower part of the grain groove, and the exhaust hole is located at the upper part of the grain groove.

[0010] In a preferred embodiment, an injection pump is fixedly mounted on the top of the base plate, and a discharge pipe and a suction pipe are fixedly mounted on both ends of the injection pump.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0012] 1. In the present application, by setting a plurality of sets of closely connected outer membrane plates, when it is necessary to injection mold foam protective covers of different sizes, the driving motor is started to drive the screw rod to rotate, so that the slide plate can be controlled to move to the left. When the slide plate moves to the left, the connecting block and the central membrane column on the left side of the connecting block can be driven to carry a plurality of sets of outer membrane plates to dock with the groove on the right side of the sealing plate. Then, according to the size of the protective cover to be injection molded, an outer membrane plate of the same size is selected, and the cylinder on the outer membrane plate at this position is started to contract. At this time, the outer membrane plate at this position moves to the right, so that the outer membrane plates at the inner and outer circles adjacent to the outer membrane plate here constitute the inner and outer membrane walls of the protective cover, and the left end of the outer membrane plate moving to the right cooperates with the groove to form the outer membrane wall. The membrane walls at both ends of the protective sleeve are formed. After this process is completed, the suction tube is connected to the molten foam injection material, and then the discharge pipe is connected to the injection tube on the left side of the injection hole corresponding to the outer sleeve membrane plate moving to the right. Then the injection pump is started to discharge the injection material into the mold cavity described above. The injection material flows in from bottom to top, and the gas in the mold cavity is discharged through the exhaust pipe on the left side of the exhaust hole. After the injection is completed and cooled, the drive motor is started to drive the screw to rotate in the opposite direction, and then all the outer sleeve membrane plates are moved to the right to separate from the sealing plate. Then the cylinder on the outer sleeve membrane plate that was moved to the right before is started to extend, so that the outer sleeve membrane plate here returns to its original position to the left, and the injection-molded foam protective sleeve can be squeezed out.

An injection pump 16 is fixedly installed on the top of the bottom plate 1, and a discharge pipe 17 and a suction pipe 18 are respectively fixedly installed at both ends of the injection pump 16.

[0019] By setting up multiple groups of closely fitted outer membrane plates 8, when it is necessary to injection mold foam protective sleeves of different sizes, the drive motor is started to drive the screw rod 5 to rotate, so that the slide plate 4 can be controlled to move to the left. When the slide plate 4 moves to the left, it can drive the connecting block 6 and the central membrane column 7 on the left side of the connecting block 6 to carry multiple groups of outer membrane plates 8 to dock with the groove 11 on the right side of the sealing plate 10. Then, according to the size of the protective sleeve to be injected, the outer membrane plate 8 that matches the size is selected, and the cylinder 9 on the outer membrane plate 8 at this position is started to contract.

[0021] First, when it is necessary to injection mold foam protective covers of different sizes, start the drive motor to drive the screw 5 to rotate, so that the slide plate 4 can be controlled to move to the left. When the slide plate 4 moves to the left, it can drive the connecting block 6 and the central membrane column 7 on the left side of the connecting block 6 to carry multiple sets of outer membrane plates 8 to dock with the groove 11 on the right side of the sealing plate 10.

[0022] Next, according to the size of the protective sleeve to be injected, a jacket membrane plate 8 that matches the size is selected, and the cylinder 9 on the jacket membrane plate 8 at this position is started to contract. At this time, the jacket membrane plate 8 at this position moves to the right, so that the jacket membrane plates 8 at the inner and outer circles adjacent to the jacket membrane plate 8 here constitute the inner and outer membrane walls of the protective sleeve, and the left end of the jacket membrane plate 8 moving to the right cooperates with the groove 11 to form the membrane walls at both ends of the protective sleeve.
