Description

Technical Field

[0001] This utility model relates to the field of heat shrink waterproof cap injection molding, and in particular to a demolding device for heat shrink waterproof cap injection molding that facilitates material removal. Background Technology

[0002] Heat-shrink waterproof caps are waterproof sealing materials used for pipe connections. They typically consist of a shell made of radiation-crosslinked polyethylene and an inner hot-melt adhesive layer. The shell provides mechanical strength and weather resistance, while the hot-melt adhesive layer provides a seal. Some caps also have grooves on the inside of the shell to increase the contact area with the hot-melt adhesive layer, resulting in a stronger bond.

[0003] Chinese patent disclosure CN223369821U discloses a plastic mold for rapid demolding. Specifically, it includes an operating table with an embedded electric telescopic rod. A movable plate is fixedly connected to the output end of the electric telescopic rod. The movable plate is slidably connected to a support platform, which is fixedly connected to the operating table. An injection molding device is mounted on the support platform, and a demolding device is mounted on the movable plate. In this rapidly demolding plastic mold, when the rotating plate rotates, the arc-shaped groove applies force to the movable block, causing the movable block to move towards the support block. Simultaneously, an L-shaped rod contacts and applies force to the sliding block, causing a clamping rod to hold the plastic part. Subsequently, a motor drives the rotating block back to its original position. During this process, the long rod is squeezed by a protrusion, causing the clamping rod to release its grip on the plastic part, thus achieving the purpose of unloading the material without manual removal.

[0004] However, it still has the following disadvantages: there is no device for rapid cooling of the demolding shell, resulting in a high surface temperature of the plastic part in contact with the mold cavity. Without cooling, it needs to rely on natural heat dissipation to cool down, which takes a long time and thus reduces demolding efficiency. Utility Model Content

[0005] The main purpose of this invention is to provide a demolding device for heat-shrinkable waterproof cap injection molding that facilitates material handling. This device can effectively solve the problem of relying on natural heat dissipation for cooling when there is no cooling, which results in a long waiting time and reduced demolding efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A demolding device for injection molding of heat-shrinkable waterproof caps that facilitates material handling includes a base, and a demolding mechanism and a cooling mechanism are provided on the top surface of the base. The demolding mechanism includes a support component and a demolding component, with the support component located on the side of the demolding component; The support assembly includes a support frame, on the top surface of which a first motor is fixedly mounted, and on the side of which a first through groove is opened. A first reciprocating threaded rod is rotatably mounted on the inner wall of the first through groove via a bearing seat, and a first support plate is threadedly fitted on the outer surface of the first reciprocating threaded rod. The demolding assembly includes several first support boxes, each with a first groove extending through its bottom surface. The top surfaces of the first support boxes are fixedly connected to the bottom surfaces of the first support plates. The outer surface of the first reciprocating threaded rod penetrates the inner top surface of the support frame and extends to the top surface of the support frame. The lower end face of the first motor output rod is fixedly connected to the upper end face of the first reciprocating threaded rod. First T-shaped plates are slidably installed on the inner walls of the several first grooves. First dampers are fixedly installed on the inner walls of the several first grooves. The bottom surfaces of the several first dampers are fixedly connected to the top surfaces of the several first T-shaped plates. An upper mold is fixedly installed on the bottom surfaces of the several first T-shaped plates.

[0007] A further improvement is that the cooling mechanism includes a water pump, a first pipe is provided through the top surface of the water pump, a second pipe is provided through the side surface of the water pump, a support is fixedly provided on the top surface of the base, and a plurality of first hydraulic rods are provided on the bottom surface of the base.

[0008] A further improvement is that the outer surfaces of several first hydraulic rods are respectively fixedly inserted through the bottom surface of the base and the bottom surface of the support and extend into the interior of the support. The upper end surfaces of several first hydraulic rod output rods are fixedly installed with lower molds, and the outer surfaces of the lower molds are respectively slidably installed with the inner wall of the support.

[0009] A further improvement is that a plurality of first annular tubes are fixedly sleeved on the outer surface of the support base, and connecting tubes are respectively opened through the sides of the first annular tubes located at the top and bottom.

[0010] A further improvement is that the bottom surfaces of the two connecting pipes respectively penetrate the side of the first annular pipe located in the middle and extend into the interior of the first annular pipe located in the middle, and a water outlet pipe is provided through the rear of the first annular pipe located below.

[0011] A further improvement is that the outer surface of the second pipe penetrates the side of the first annular pipe located below and extends into the interior of the first annular pipe located below.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By setting up a demolding mechanism, a first motor drives a first reciprocating threaded rod to rotate, which is adjusted according to the height of the heat shrink waterproof cap mold. At the same time, a first damper is set up to move the first T-shaped plate and the upper mold, thereby effectively buffering, facilitating rapid processing and easy unloading. By setting up a cooling mechanism and using a first hydraulic rod to move the lower mold to a suitable height, it is easier to remove material from the internal mold. At the same time, a water pump is set up to transport cold water into the first annular pipe for rapid conveying of the support surface, thus facilitating production. Attached Figure Description
