The invention discloses a cold-runner mould for a thermosetting plastic. The cold-runner mould comprises an upper mould and a lower mould. The upper mould and the lower mould are arranged in parallel.An upper runner plate is mounted at the bottom of the upper mould, a lower runner plate is mounted right below the upper runner plate, a runner is arranged in a position, close to the upper end, in the upper runner plate, a plate A is mounted on the surface of the upper end of the upper mould, a heat isolating plate is arranged between the upper end surface of the plate A and the lower runner plate, and front mould cores are arranged in a middle position in the lower mould and the plate A. The mould can prevent a thermosetting plastic from being cured to reduce the number of times of disassembling and examining the mould, so that the production efficiency is improved. The pressure in a cavity is reduced, and the exhausting effect is increased, so that the product moulding percent of passis improved, the problem that the forming height of a large product is insufficient is solved, the using flexibility to the environment is increased, and wear between the upper runner plate and a valve needle can be reduced, so that a material leakage risk is further reduced. Air circulates above the heat isolating plate, so that a heat-dissipating effect is achieved.

The invention discloses a universal fixture for fluid pipeline belt pressure leaking stoppage and relates to the technical field of fluid pipelines. The universal fixture for the fluid pipeline belt pressure leaking stoppage comprises an upper clamping collar and a lower clamping collar; sleeves distributed in a circumferential array are fixedly installed on the outer surface of the upper clampingcollar; sleeves distributed in a circumferential array are fixedly installed on the outer surface of the lower clamping collar; a pressure detection meter is fixedly inserted into the right side of the upper clamping collar; the interiors of the sleeves are in threaded insertion with adjusting screw rods; rotary knobs are fixedly installed at the top ends of the adjusting screw rods; and antiskidgrooves laid uniformly are formed in each of the upper side and the lower sider of the front of the upper clamping collar. The universal fixture for the fluid pipeline belt pressure leaking stoppageis high in tensile strength and good in structural stability; enough and lasting radial pressure can be exerted after the clamping collars are tightly hooped so as to allow the fixture to be compressed on the excircle surface of a pipeline, so that the sealability is improved, the leaking stoppage effect is improved, and the potential safety hazard is eliminated; and pressure on the inner side ofthe fixture can be detected in real time, so that a user conveniently judges whether the problem of oil leakage or gas leakage happens according to the pressure on the inner side, and disconnecting detection is avoided.

The invention relates to an EEG electrode cap, comprising a cap body, an electrode and a lead wire; the electrode includes a fixing ring, an electrode sheet and a bonding sealant; the middle part of the fixing ring has a cavity with both ends open and connected, and the electrode is arranged in the cavity Sheet positioning table, the electrode sheet is placed on the electrode sheet positioning table; one side of the electrode sheet is fixed with the inner wall of the fixed ring cavity by bonding sealant, and the other side is combined with the conductive adhesive in the conductive adhesive chamber; the outer cylindrical surface of the fixed ring There are fixed grooves for fixing the electrode and the cap body; after the adhesive sealant is cured, there is a conductive glue hole connected to the conductive glue chamber; the electrode sheet and the lead wire passing through the lead wire hole on the fixing ring line connection. The advantages of the present invention are: the integrated design of the electrode sheet and the fixing ring is convenient for skin pretreatment, glue injection and glue replenishment; convenient and reliable positioning, close fit with the scalp, comfortable to wear, especially suitable for high density, long-term sleep, brain magnetism Figure and EEG measurement in MRI environment.
