Detailed Description
The following describes in further detail embodiments of the present invention.
As shown in fig. 1 and 2, a rubber cold runner mold of the present invention includes a main body 1, and a cavity 10 serving as a runner of rubber is provided inside the main body 1. The upper part of the main body 1 is provided with 1 feeding hole (not shown) communicated with the cavity 10, and the lower part of the main body 1 is provided with 4-16 distributing nozzles 5 communicated with the cavity 10. A cooling oil pipe 2 is arranged in the cavity 10, an oil inlet (not shown) and an oil outlet 3 are arranged on the main body 1, and two ends of the cooling oil pipe 2 are respectively connected with the oil inlet and the oil outlet 3. The oil inlet and outlet 3 are disposed on the side of the main body 1 and communicate with an external oil pump (not shown) and an oil tank (not shown), and a heating or cooling device for heating or cooling the rubber in the cavity 10 by controlling the temperature of the oil.
The cooling oil pipe 2 is made of metal with low thermal conductivity, and particularly special die steel with low thermal conductivity is used for hardening and blackening, so that the temperature can be slowly adjusted to avoid the phenomenon of glue death.
The cooling oil pipe 2 and the distributing nozzle 5 have a preset gap, usually at least 10mm, or are arranged in a staggered manner, so that the distributing nozzle 5 is prevented from being blocked.
Further, a temperature detecting hole 7 for accommodating a temperature controller (not shown) is formed in a side surface of the main body 1, and the temperature detecting hole 7 is not communicated with the cavity 10; the temperature controller is used in cooperation with heating or cooling equipment.
Furthermore, a glue inlet 4 with a through hole 12 is arranged at the position of the feed inlet, an annular heat insulation sleeve 9 is sleeved outside the glue inlet 4, and an annular positioning ring 8 is sleeved outside the heat insulation sleeve 9 to fix the heat insulation sleeve 9 and the glue inlet 4. The heat insulation sleeve 9 can effectively avoid the phenomenon that the temperature of the glue inlet nozzle 4 is diffused to the main body 1, so that the flow speed is reduced due to the over-low temperature.
Further, the distributing nozzle 5 is arranged on the main body 1 through threaded connection so as to be convenient to replace.
Further, the lower part of the main body 1 is provided with a plurality of cylindrical positioning guide posts 6 protruding from the lower surface of the main body 1 for positioning when the main body 1 and the mold are closed.
The main part 1 is the cuboid structure that highly is 90 ~ 110mm, and the height of cavity 10 is 30 ~ 40 mm. The design ensures that the invention can be suitable for most of the existing rubber injection molding systems at present and has higher universality. If the height of the cavity 10 is too high, the residual glue is too much, and the temperature control effect is poor; too low may cause dead glue or blockage due to other reasons.
The utility model discloses a rubber cold runner mould's theory of operation jets out rubber material to advancing jiao zui 4 from the vulcanization injection machine, by advancing jiao zui 4 and getting into cavity 10, then by dividing during the branch material mouth 5 divides to shoot each die cavity of mould. In the process, the cooling oil flowing in through the oil inlet controls the ejection temperature of the rubber through the cooling oil pipe 2, so that the flowing of the rubber is ensured. The temperature controller in the temperature detection hole 7 is used for monitoring the cooling effect.
The above embodiment is only one embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
