Abstract
The utility model relates to a core rod for vulcanizing silicone rubber tubes, and aims to provide an apparatus capable of effectively improving the production efficiency of the silicone rubber tubes and reducing energy consumption and the production cost. The technical scheme is that the structure of the outer circumferential surface of a rotary main body of the core rod for vulcanizing the silicone rubber tubes is consistent with the structure of a through-hole of each silicone rubber tube; the core rod is characterized in that a coaxially distributed blind hole is formed on the rotary main body; an electric heating rod is arranged in the blind hole; and the depth of the blind hole is 80 to 90 percent of the length of the rotary main body.
Description
Technical field
The utility model relates to a kind of making utensil of power cable silicone rubber tube, in particular for the plug of silicone rubber tube sulfuration.
Background technology
Silicone rubber tube (especially the 35KV cable is used silicone rubber tube) is the conventional accessory in the power transmission line, need be pre-formed in factory.Conventional manufacture craft is injection moulding on injection molding, and directly is fixed to product through the sulfuration of heating.
Usually product is direct baking in die cavity; The wall portion of existing silicone rubber tube is thicker, required heat time heating time long (every mould needs about 800 seconds); Production efficiency can't improve, and energy consumption and production cost also are difficult to further reduction.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes the above-mentioned background technology, and a kind of auxiliary implement of silicone rubber tube sulfuration usefulness is provided, and this utensil should be able to effectively improve the production efficiency of silicone rubber tube, and cuts down the consumption of energy and production cost.
The technical scheme that the utility model provides is: plug is used in the silicone rubber tube sulfuration, and the outer circumference surface structure of its jatharapanvartanasana main body is consistent with the hole configuration of silicone rubber tube; It is characterized in that being shaped on the said jatharapanvartanasana main body blind hole of coaxial arrangement, blind hole is built-in with electrically heated rod.
The degree of depth of said blind hole is 80-90% of a jatharapanvartanasana principal length.
The beneficial effect of the utility model is: because silicone rubber tube is in when sulfuration, outer circumference surface and through-hole wall portion are heated simultaneously, and the heat passing time is obviously accelerated, and has also just significantly reduced cure time (cure time is reduced to every mould 500 seconds); Not only increased substantially production efficiency (per 8 hours be increased to 45 moulds from 30 original moulds), also obviously reduced energy consumption, production cost also is able to further decline.
Description of drawings
Fig. 1 is the main TV structure sketch map of the utility model.
The specific embodiment
Plug is used in the silicone rubber tube sulfuration, and its structure is as shown in the figure; Owing to directly be used for injection molding, obviously the outer circumference surface of its jatharapanvartanasana main body 1 structure is consistent with the hole configuration of silicone rubber tube.
The improvement of the utility model is the blind hole 1-1 that on this jatharapanvartanasana main body, is shaped on coaxial arrangement, and blind hole is built-in with electrically heated rod 2.The openend of this blind hole generally should be positioned at the fixing end of plug and mould, is beneficial to the layout of electrically heated rod lead 2-1; The degree of depth of blind hole can require to confirm according to the structure and the sulfuration process of silicone rubber tube; Usually the degree of depth can be decided to be 80-90% of jatharapanvartanasana principal length.Directly outsourcing of electrically heated rod, its watt level is according to also requiring to confirm according to sulfuration process.
The operation principle of the utility model is: use plug owing in the through hole of silicone rubber tube, insert the silicone rubber tube sulfuration in advance; So the silicone rubber tube in die cavity when sulfuration, energising simultaneously makes the electrically heated rod heating, heats simultaneously inside and outside making silicone rubber tube, thereby accelerates cure time.
Claims (2)
