Abstract

PURPOSE: An apparatus for separating products from a mold is provided to enable product to be easily separated from a lower mold due to condensation formed by cooled air by cooling air between the product and the mold. CONSTITUTION: An apparatus for separating products from a mold comprises a low-temperature air feeder(30) and an injection nozzle(40). The low temperature feeder comprises a mold(20). The low temperature feeder produces the air of the low temperature. The injection nozzle sprays low temperature air supplied from a low temperature supplying device to a product(100).

Description

Separation device for detaching products from a mold.

The present invention relates to a separator for separating a product from a mold, and more particularly, to a separator that allows the product to be easily separated from the mold when the product is molded into the mold.

In general, injection molding operations can be classified into two categories, one being a die casting mold and a plastic mold, that is, an injection molding mold.

Due to the shape of the bend in both cases, the eject pin is discharged by a deliberate method. In addition, mold release agent is used to make molding well and at the time of discharging, and there is little idling and loss of raw materials due to unmolding due to high heat and temperature loss, and unreasonable workability that release agent causes environmental problems as chemicals for a while. Cause Recently developed metal and plastic materials are softened when heated to increase plasticity, so that processing such as casting and extrusion molding can be performed, but the reality is that they do not have continuity.

It is made by such a casting, injection, extrusion mold, each mold consists of the upper and lower molds, the product unit is placed on the lower mold. The molded product should be separated and the release agent should be applied.

These parting materials are different depending on the purpose of use and the manufacturer, but the parting agent is applied to the contact surface between the mold and the cooking unit for the purpose of easily separating the product from the mold. Such release agents are stearic acid, waserine, Light lubricants, silicone greases and the like are used.

However, since the release agent is made of a chemical substance, it not only worsens the working environment, but also pollutes the environment when discharged, and also increases the manufacturing cost for purification.

Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to provide a separation device for easily separating a product from a mold without using a release agent.

This object is achieved by the present invention, in accordance with an aspect of the present invention, the separation device for separating the product from the mold, the mold is provided, and a low temperature supply device for producing low temperature air; It is composed of a spray nozzle for injecting the low-temperature air supplied from the low temperature supply device to the molded product, characterized in that the product is easily separated from the mold by the low-temperature air injected from the injection nozzle do.

And it characterized in that the transfer means for moving the injection nozzle is further provided.

In addition, the low temperature supply device and a compressor for compressing the refrigerant gas; A condenser for condensing the high temperature and high pressure refrigerant compressed by the compressor; And an evaporator configured to evaporate the refrigerant condensed in the condenser and produce low temperature air by the refrigerant evaporated in the evaporator.

In the present invention, the low temperature supply device is characterized in that to produce low-temperature air by the Peltier effect (Peltier 效果).

According to the above configuration of the present invention, the air between the product and the lower mold is cooled by the injection of low-temperature air, the product is easily separated from the lower mold by the dew formed by the cooled air of the release agent The effect is to avoid use.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, and like reference numerals designate like parts throughout the drawings.

1 is a block diagram of a separator according to an embodiment of the present invention.

As shown in the figure, the separator according to the present invention shown by the reference numeral 10 is provided with a mold 20, is composed of a low temperature supply device 30, the injection nozzle 40 and the conveying means 50 and the like. .

The low temperature supply device 30 is a device for producing low temperature air, and may be configured by gas compression or electronic.

In the gas compression type, a refrigerant gas is compressed to a high temperature and a high pressure by a compressor, which is mainly used in a domestic refrigerator, and then the refrigerant gas of the high temperature and high pressure is condensed by being sent to a condenser. The liquefied refrigerant is easily evaporated at a low temperature while the pressure is reduced in the capillary tube, and then the liquefied refrigerant is vaporized in the cooler. At this time, because it absorbs the heat of vaporization, the surrounding air is deprived of heat and the temperature decreases. The low temperature air generated as described above is injected to the lower mold 23 by the injection nozzle 40.

The injection nozzle 40 injects low-temperature air between the lower mold 23 and the product 100. When the low-temperature air is injected, the air between the lower mold 23 and the product 100 is injected. As condensation occurs at a temperature below the dew point, condensation occurs. The dew generated as described above functions as a release agent, so that the product 100 can be easily separated from the lower mold 23.

The temperature of the air injected from the injection nozzle 40 is preferably 1 ~ 3 ℃, according to a number of experiments by the applicant of the dew is well formed at the temperature, and also the product 100 produced by the temperature change The impact could be minimized.

In addition, the low temperature supply device 30 may be electronic. The electronic type produces a low temperature air by using a Peltier effect. When two types of different conductors are brought into contact with each other and a DC current is applied thereto, heat generation and absorption occur at the junction. As such, the air is cooled and supplied to the injection nozzle 40 at a portion where heat is absorbed. The electronic type is small in capacity and preferably used in a precise working environment.

And it can be transported in conjunction with the position of the upper mold 21 of the injection nozzle 40, as shown in Figure 2a and 2b when the upper mold 21 is moved to the lower nozzle ( 40 is waiting at the position retracted from the mold 20, when the upper mold 21 completes the molding process and moves to the upper portion, the injection nozzle 40 by the transfer means 50 is the product (100) To inject low temperature air. The transfer means 50 may be composed of pneumatic or screw.

What has been described above is only one embodiment for implementing the separation device according to the present invention, the present invention is not limited to the above-described embodiment without departing from the gist of the present invention as claimed in the following claims Anyone with ordinary knowledge in the field of the present invention will have the technical idea of the present invention to the extent that various modifications can be made.
