Abstract

The present invention of a device for instantly pre-heating dies comprises a heat conductive coil disposed between a first die and a second die. The heat conductive coil is a coil body in spiral shape having characteristics of conducting high cycle wave induction heat energy. When the first and the second dies are separated by a mechanical arm, the heat conductive coil is disposed between the first and the second dies, so that high cycle wave induction heat can take effect between the dies. Thus the surfaces of the first and the second dies can be pre-heated. As a result, not only its pre-heated efficiency is enhanced, electric energy can also be saved and at the same time, melted plastic inside the dies can flow smoothly.

1. The technical field to which the invention belongs] Species: ":" belongs to a method and device for mold preheating, in particular, a method and device for instantaneous preheating of the surface of the mold core by a leaf. II. Prior technology] Press In general, when the mold is applied to injection molding processing, in order to smoothly make the molding, the plastic melt is injected into the pouring gate of the mold to stabilize the flow, and to avoid early cooling and molding of the plastic melt. Therefore, before the mold is closed, the △ mold and The master mold is heated to a predetermined temperature in advance, so that the plastic melt can be reliably and smoothly flowed into the mold cavity and then cooled and formed. / According to the prior art, the preheating structure of the injection molding mold is generally set on the male mold Or the heating structure in the mother mold is "fixed", and it can be heated by using package heat or "Southern Zhoubo". As shown in Figure 1, it is the previous creation of the present inventor, and the announcement No. 4637 1 8 "child The female instantaneous preheating mold t drive device "is composed of a male mold and a female mold. The male mold is provided with a core, a heating system and a cooling system, and the female mold is provided with a mold and a filling port. Decree The male mold is provided with a child-and-mother-type child mold and a mother mold according to the heating system and the cooling system. The rear end surface of the child mold is provided with a high frequency induction heating that is slightly larger than the mold core groove volume of the ceramic block or the plastic-steel soil package. The coil heating system, and the cooling water pipe of the cooling system is installed in the mother mold. According to the male mold clamping stroke, the 'sub-mold' must be introduced to quickly warm up first, and then the child and mother mold are simultaneously closed on the mother mold and quickly. Injection molding and cooling and demoulding achieve the effects of small and fast preheating volume of the child parting mold and synchronous cooling of injection. However, this customary creation of preheating vibration fixed in the mold, whether it is electric heating or high frequency Heating method, because the high-temperature heat energy emitted by it must be transmitted to the entire pair of molds,

'It takes longer to warm up and requires more time because of the increase in the rate of plastic melts. This is lacking.' When the plastic melts form the plastic melts smoothly, the time it takes to cool down is therefore 'how' to improve It has become a concern for the industry to make the plastic slurry flow smoothly to the mold cavity, so the interval is relatively long, and the preheating of the mold core part is the flow path of the mold core part, which often flows smoothly due to insufficient preheating temperature. Molding at the cavity, forming one of poor quality = one, and the other missing part is that when the cooling time is long and flows into the mold six, the mold must be cooled. However, 'because the mold preheating temperature is relatively long, relatively ^ pairs Increase, especially the cooling of the mold kernel is more time-consuming, and the missing direction of the "mold kernel" preheating and excessive cooling time. In addition, there is another type of exposed display, which is a "head for preheating the mold", "fuel pipe", and "support gas stove". The cover is pierced and arranged with a regular number of nozzles. One end is screwed at the gas stove head to form a circulation body. One end of the supporting frame is set at the fuel tube of the forging machine or injection molding machine. The fuel can be controlled to open and burn. The fuel is sprayed out of the fuel in a large amount and evenly sprayed out. The forging die and injection die are composed of the forging die, which is convenient for the forging machine or injection molding die. The preheating structure is as shown in Figure 2. , Including a "gas furnace" and "regulating valve", in which the combined furnace head cover is formed on the body on the step surface of the ventilation chamber ring, and the fuel pipe, the other end is The fuel pipe is pivoted to the middle of the fuel pipe, and the other is on the other side, and the regulating valve is connected to the opening and closing regulating valve, and is adjustable, so that the gas burner can burn the combustion machine or injection molding machine. Upper and lower rooms Warm-up state machines like forging operating temperature of injection molding, or as add
