The easy-tear strip 120 is attached to the easy-tear region 113. The sealing members are used to seal the first end 111 and the second end 112, respectively.

The embodiment of the utility model provides a hydrogel mould pipe 100 includes mould pipe body 110, and mould pipe body 110 is equipped with easy tear strip 120 including easily tearing district 113, easily tearing district 113. First, either end of the mold tube body 110 is sealed with a sealing member, then the hydrogel is loaded into the hydrogel mold tube 100, and then the other end of the mold tube body 110 is also sealed with a sealing member. The procedure for removing the cured hydrogel was as follows: pulling the easy-tear strip 120, the easy-tear strip 120 drives the easy-tear region 113, so that the easy-tear region 113 falls off from the die tube body 110, that is, the die tube body 110 forms a tear in a direction from the first end 111 to the second end 112, and the hydrogel can be taken out from the tear. In the process, the die tube body 110 does not need to be broken, the operation is simple and easy to implement, the problems that the hydrogel forming operation is complex and difficult to take out in the experiment can be effectively solved, and the personal safety is ensured. In addition, the hydrogel mold tube 100 is simple in structure and low in production cost.

In one embodiment, referring to fig. 1 to 2, the sidewall of the die tube body 110 further includes a non-tearing region 114, the non-tearing region 114 is connected to the easy-tearing region 113, and the thickness of the easy-tearing region 113 is smaller than that of the non-tearing region 114. Specifically, the cross-section of the die tube body 110 is circular, square, triangular or elliptical. For example, the die tube body 110 is a circular tube, a square tube, or the like, and is not particularly limited herein.

Further, referring to fig. 1-2, the material of the mold tube body 110 is not sticky to hydrogel. The die tube body 110 may be a PE tube or a PP tube. Wherein PE refers to polyethylene, Polyethylene (PE) is a thermoplastic resin obtained by polymerizing ethylene, and industrially, polyethylene also includes a copolymer of ethylene and a small amount of α -olefin. Polyethylene is odorless, nontoxic, has wax-like hand feeling, excellent low-temperature resistance, good chemical stability, resistance to most of acid and alkali erosion, insolubility in common solvents at normal temperature, small water absorption of less than 0.01%, excellent electrical insulation property and good impact resistance. PP refers to Polypropylene, Polypropylene (PP for short) is a polymer formed by propylene addition polymerization, is a white waxy material, is transparent and light in appearance and flammable, can resist corrosion of acid, alkali, salt solution and various organic solvents at the temperature of below 80 ℃, can be decomposed under the action of high temperature and oxidation, and is widely applied to the production of fiber products such as clothes and blankets, medical instruments, automobiles, bicycles, parts, conveying pipelines, chemical containers and the like, and is also used for packaging food and medicines. The die tube body 110 is made of PP or PE, which is beneficial to reducing the production cost. The die tube body 110 is made of a transparent plastic tube, so that a tester can conveniently observe the hydrogel, and the die tube body is also used for heating forming and photo-initiation forming.

Further, referring to fig. 1 and fig. 2, when the die tube body 110 is produced, the thickness of the easy-to-tear region 113 needs to be much thinner than that of the non-tear region 114 (for example, the easy-to-tear region 113 is thinned by increasing the pressure), so that the tester only needs to pull the easy-to-tear strip 120, and the easy-to-tear strip 120 can drive the easy-to-tear region 113, so that the easy-to-tear region 113 falls off from the die tube body 110, thereby forming a tear, and the hydrogel can be taken out from the tear. In the process of taking out the hydrogel, the die tube body 110 does not need to be broken, the easy-to-tear strip 120 only needs to be pulled, the operation is simple and easy to implement, the problems that the hydrogel forming operation is complex and difficult to take out in an experiment can be effectively solved, and the personal safety can be ensured.

In one embodiment, referring to fig. 1-2, the easy-tear strip 120 is pressed on the easy-tear region 113. Specifically, when the die tube body 110 is produced, the easy-tear strip 120 is pressed, and the easy-tear strip 120 is pressed on the easy-tear region 113. Thus, when the easy-tear strip 120 is pulled, the easy-tear strip 120 can drive the easy-tear area 113 to fall off from the die tube body 110. As another alternative, the easy-tear strip 120 is adhered to the easy-tear region 113. Specifically, the tear strip 120 may also be adhered to the tear area 113 by glue.

In one embodiment, referring to fig. 1-2, the tear strip 120 includes a free end 121, and the free end 121 extends out of the die tube body 110. Specifically, the free end 121 can be held by hand or a tool by the experimenter, and the easy-tear strip 120 and the easy-tear region 113 can be torn off. The design that the free end 121 stretches out of the die tube body 110 facilitates the test personnel to tear the easy-to-tear strip 120, and improves the convenience of taking out the hydrogel.

In one embodiment, referring to fig. 1-2, the tear-off region 113 has a notch (not shown) disposed at an end of the die tube body 110 and near the free end 121. The arrangement of the notch is more convenient for the easy-tearing strip 120 to drive the easy-tearing area 113 to fall off from the die tube body 110, so as to form a tearing opening.

In one embodiment, referring to fig. 1 to 2, the sealing member is a sealing cap 130, and there are two sealing caps 130, and the two sealing caps 130 are respectively disposed on the first end 111 and the second end 112.

The sealing cover 130 and the sealing plug 140 are made of PP and PE materials, which is beneficial to reducing the production cost. It will be appreciated that other materials that do not adhere to hydrogel may be used for the sealing cap 130 and the sealing plug 140, and are not limited in this regard.

As another alternative, referring to fig. 1 to 2, the sealing member includes a sealing cap 130 and a sealing plug 140, the sealing cap 130 is disposed on the first end 111, and the sealing plug 140 blocks the second end 112; alternatively, the sealing cap 130 is disposed on the second end 112, and the sealing plug 140 blocks the first end 111. Taking the sealing cap 130 covering the first end 111 and the sealing plug 140 blocking the second end 112 as an example, the hydrogel mold tube 100 is loaded with hydrogel as follows: firstly, the second end 112 of the die tube body 110 is plugged by using the sealing plug 140, and the easy-to-tear strip 120 is stuck on the die tube body 110; next, hydrogel is injected into the mold tube body 110 from the first end 111, and the first end 111 is covered with the sealing cap 130. Thus, the hydrogel can be loaded into the mold tube body 110 without spilling. The die tube body 100 is described as a circular tube. When the die pipe body 110 is a circular pipe, the die pipe body 110 may be designed to have circular pipes with different diameters as required. When the sealing element adopts the sealing cover 130 and the sealing plug 140, correspondingly, the sealing cover 130 and the sealing plug 140 need to be manufactured according to the diameter of a circular tube, so that the size of the sealing element is matched with that of the die tube body 110, and the hydrogel is prevented from leaking in the die tube body.

As another alternative, referring to fig. 1-2, the sealing element includes a sealing plate (not shown) welded to the die tube body 110, and the sealing plate seals the first end 111 and the second end 112, respectively. The sealing plate and the die tube body 110 are made of the same material. When the seal is a seal plate, the process of loading the die tube body 110 with hydrogel is as follows: first, the second end 112 is welded to the upper sealing plate using a plastic welding gun so that the second end 112 is sealed; next, hydrogel is injected into the mold tube body 110, and finally, the first end 111 is welded to the upper sealing plate using a plastic welding torch, so that the first end 111 is sealed. Thus, the hydrogel can be loaded into the mold tube body 110 without spilling.

First, either end of the mold tube body 110 is sealed with a sealing member, then the hydrogel is loaded into the hydrogel mold tube 100, and then the other end of the mold tube body 110 is also sealed with a sealing member. The procedure for removing the cured hydrogel was as follows: pulling the easy-tear strip 120, the easy-tear strip 120 drives the easy-tear region 113, so that the easy-tear region 113 falls off from the die tube body 110, that is, the die tube body 110 forms a tear in a direction from the first end 111 to the second end 112, and the hydrogel can be taken out from the tear. In the process, the die tube body 110 does not need to be broken, the operation is simple and easy to implement, the problems that the hydrogel forming operation is complex and difficult to take out in the experiment can be effectively solved, and the personal safety is ensured.
