Abstract
The invention provides a cold runner device on rubber injection equipment. The cold runner device comprises a cold runner plate, a cushion plate, a thermal insulation plate and a heating plate arranged in sequence from top to bottom; a positioning ring is arranged on the cold runner plate; a shunt way is formed in the cushion plate; injection liquid flows into the shunt way through the positioning ring; runners communicated with each outlet of the shunt way are formed in the thermal insulation plate and the heating plate; and the injection liquid flows out from each runner of the thermal insulation plate and the heating plate to enter each mold cavity after being shunted through the shunt way. The thermal insulation plate separates the cold runner plate from the heating plate; a sizing material in the shunt way cannot be heated and vulcanized, so that the waste of the sizing material is reduced, and the production cost is reduced; the cold runner device directly feeds each mold cavity through the shunt way; after each mold product is produced, the device only needs to be dismantled, and the heated and vulcanized sizing material in the heating plate is removed; the time of removing the sizing material out of a film is shortened; the working intensity of workers is reduced; and the production efficiency is improved.
Description
Technical field
The invention belongs to rubber injecting equipment technical field, particularly relate to the cold runner device on a kind of rubber injecting equipment.
Background technology
Generally speaking, rubber is heat cured, and plastics are thermoplastic.Thermoset rubber is under certain pressure condition, the high resiliency state of solidification is become after being heated to uniform temperature, usually, the waste material of thermoset rubber can not recycling, the flow passage system of most of rubber injection mold is TOP-TIP, after injection, sizing material in flow passage system and the sulfuration simultaneously of the sizing material in mould, take out when the demoulding simultaneously, the sizing material taken out in flow passage system is separated rear as obsolete material process with goods, therefore, in production as vehicle shock pad, during the rubbers such as sealing ring, if still adopt common moulding process mode to process, the sizing material be wasted in inside runner will be a lot, when sizing material especially your time, as fluorubber, Polypropionate etc., the cost producing each mechanograph will be very high.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of cold runner device of rubber injecting equipment, to reduce sizing material waste, reduces production cost.
For achieving the above object and other relevant objects, the invention provides the cold runner device on a kind of rubber injecting equipment, comprise the cold flow guidance tape, backing plate, thermal insulation board and the heating plate that set gradually from top to bottom, described cold flow guidance tape is provided with locating ring, described backing plate is provided with runner, and parenteral solution flows in runner by locating ring; Described thermal insulation board and heating plate are provided with the runner with each outlet of runner, and parenteral solution is entered in each die cavity from each runner outflow of thermal insulation board and heating plate after being shunted by runner.
Preferably, described cold flow guidance tape, backing plate, be bolted between thermal insulation board and heating plate.
As mentioned above, cold runner device of the present invention, has following beneficial effect:
1, cold flow guidance tape and heating plate separate by thermal insulation board of the present invention, and the sizing material in runner can not through baking, and sizing material waste reduces, and production cost reduces.
2, the present invention directly feeds in raw material to each die cavity by runner, after having produced each mechanograph, this device is only needed to take apart, then the sizing material through baking in heating plate is removed, film removes the time shorten of sizing material outward, workman's working strength reduces, and production efficiency is further enhanced.
3, the shaping novel process of cold runner injection of the present invention to realizing high-quality, efficient, low consumption, the rubber of low cost is produced positive meaning, that rubber produces the new way realizing mechanization and automation, it will advance quick foundation and the development of energy-saving, the environmentally friendly rubber secondary industry of resource greatly, improve the economic benefit of rubber industry, realize the sustainable development of rubber industry.

Detailed description of the invention
By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present invention and effect easily.
As shown in Figure 1, the invention provides the cold runner device on a kind of rubber injecting equipment, comprise the cold flow guidance tape 2, backing plate 3, thermal insulation board 4 and the heating plate 5 that set gradually from top to bottom, cold flow guidance tape 2 is provided with locating ring 1, backing plate 3 is provided with runner, and parenteral solution flows in runner by locating ring 1; Thermal insulation board 4 and heating plate 5 are provided with the runner with each outlet of runner, and parenteral solution is entered in each die cavity from each runner outflow of thermal insulation board 4 and heating plate 5 after being shunted by runner.
The present invention makes traditional hot runner molding technique into cold runner moulding process, cold flow guidance tape 2 and heating plate 5 is separated by thermal insulation board 4, and the sizing material in runner can not through baking, and sizing material waste reduces, and production cost reduces; Simultaneously, backing plate 3 is provided with runner, directly feed in raw material to each die cavity by runner, after having produced each mechanograph, only need this device to take apart, then remove in heating plate 5 through the sizing material of baking, film removes the time shorten of sizing material outward, workman's working strength reduces, and production efficiency is further enhanced.
Cold flow guidance tape 2, backing plate 3, to be bolted between thermal insulation board 4 and heating plate 5, to be convenient to installation and removal, to meet injection pressure and the locked mode pressure of equipment simultaneously.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
