Description

Temperature control device for injection molding machine {Apparatus for Regulating Temperature for Injection Molding Machine}

The present invention relates to an injection molding machine that performs injection molding to produce an injection product.

Injection molding is the most widely used manufacturing method for manufacturing plastic products. For example, in products such as televisions, mobile phones, PDAs, and the like, various parts including covers and cases may be manufactured through injection molding.

In general, the manufacture of products through injection molding is made through the following processes. First, a molding material with pigments, stabilizers, plasticizers, fillers, etc. added is put into a hopper to make it in a molten state. Next, the molding material in the molten state is injected into the mold and then solidified through cooling. Next, after extracting the solidified molding material from the mold, unnecessary parts are removed. Through these processes, injection products having various types and sizes are manufactured. As a facility for performing such injection molding, an injection molding machine is used.

5 to 13 , the cover member 41 may be formed of fabric. Accordingly, the injection device 1 according to the present invention can achieve the following effects when compared to the embodiment in which the cover member 41 is formed of metal.

First, in the injection device 1 according to the present invention, since the cover member 41 is formed of fabric, the cover member 41 is manufactured in comparison with the embodiment in which the cover member 41 is formed of metal. It is possible to improve the easiness of the processing process for the above and the assembly process of coupling the cover member 41 to the first partition member 311 and the second partition member 312 .

Second, in the injection device 1 according to the present invention, since the cover member 41 is formed of fabric, the weight of the cover member 41 is compared to the embodiment in which the cover member 41 is formed of metal. can reduce Accordingly, the injection device 1 according to the present invention can reduce the load applied to the barrel 2 due to the cover member 41, thereby reducing the degree of sagging in the barrel 2 have. In addition, the injection device 1 according to the present invention can reduce the size of the rigidity that the barrel 2 must have in order to support the cover member 41 . Therefore, in the injection apparatus 1 according to the present invention, it is possible to reduce the material cost by reducing the thickness of the barrel 2 when compared to the embodiment in which the cover member 41 is formed of metal, so that the Manufacturing cost can be reduced.

The cover member 41 may be formed of a fabric including a heat insulating material. Accordingly, the injection device 1 according to the present invention can additionally have a heat insulation function for the temperature control area TA by using the cover member 41, so that the temperature control area TA is generated. heat loss can be further reduced. Accordingly, the injection apparatus 1 according to the present invention further reduces the amount of energy consumed to operate the heating unit 2 , thereby contributing to further reducing the process cost for injection molding. In addition, the injection device 1 according to the present invention can reduce the degree of increase in the temperature of the cover member 41 even when the temperature of the temperature control area TA increases by using a heat insulating material. Therefore, the injection device 1 according to the present invention can reduce the risk of a safety accident due to high temperature even when a worker located in the vicinity comes into contact with the cover member 41 .

When the cover member 41 is formed of fabric or a fabric including a heat insulating material, the support member 42 is bent due to the flexibility of the cover member 41, so that the heating unit ( 2) can be prevented from coming into contact. Accordingly, the injection device 1 according to the present invention may be implemented such that the temperature control area TA of a size sufficient to accommodate the heat generated by the heating unit 2 is maintained. In addition, the injection device 1 according to the present invention may be implemented such that an air layer exists between the cover member 41 and the support member 42 . Accordingly, the injection device 1 according to the present invention can reduce the effect of the heat generated by the heating unit 2 on the temperature of the cover member 41 due to the air layer. Therefore, since the injection device 1 according to the present invention can reduce the thickness of the cover member 41 , it is possible to reduce the manufacturing cost for manufacturing the cover member 41 . The support member 42 may be formed of a material having a stronger rigidity than that of fabric.

5 to 13 , the cover member 41 may be formed of a non-metal material. Accordingly, in the injection device 1 according to the present invention, when the cover member 41 is formed of metal, the cover member 41 is not exposed to the temperature of the temperature control area TA. It is possible to reduce the thermal deformation that occurs. Therefore, the injection device 1 according to the present invention can increase the cycle of maintenance work such as replacement and repair of the cover member 41 due to thermal deformation, thereby contributing to increasing the productivity of the injection product through an increase in the operation rate. can

4 and 14 , the temperature control device 1 for an injection molding machine according to the present invention may include a supply unit 5 .

The supply unit 5 supplies cooling gas. The cooling gas supplied by the supply unit 5 may be injected into the cover unit 4 . Accordingly, the temperature control device 1 for an injection molding machine according to the present invention is heated using the heating unit 2 and cooled using the cooling gas supplied by the supply unit 5 to the inside of the barrel 210 . It is possible to improve the accuracy of the operation of adjusting the positioned molding material to a preset temperature. Looking at this in detail, it is as follows.

First, when the molding material is adjusted to a preset temperature only by the heating unit 2, the heating unit 2 heats the barrel 210 so that when the molding material reaches a preset temperature, the barrel 210 heating can be stopped. However, even when the heating unit 2 stops heating the barrel 3 , the molding material may exceed a preset temperature due to residual heat remaining in the barrel 210 . In addition, when the molding material becomes less than a preset temperature after the heating unit 2 stops heating the barrel 210 , the heating unit 2 resumes heating the barrel 210 . However, since it takes a predetermined time until the molding material is heated as the heating unit 2 heats the barrel 210, the molding material can be moved forward (in the direction of the FD arrow) in a state below the preset temperature. . Therefore, it is difficult to adjust the molding material to a preset temperature only by the heating unit 2 .

Next, when the molding material is adjusted to a predetermined temperature using the heating unit 2 and the supply unit 5 , the heating unit 2 heats the barrel 210 so that the molding material is heated to a predetermined temperature. When reaching or approaching a preset temperature, the supply unit 5 may inject a cooling gas into the cover unit 4 . Accordingly, the supply unit 5 may reduce the effect of residual heat remaining in the barrel 210 on the temperature of the molding material.

Therefore, in the comparative example, the cooling gas cannot be injected into the first intermediate point CP1 of the first temperature control area TA1 based on the first axial direction (X-axis direction), so that the first temperature control It is difficult to control the area TA1 to a uniform temperature as a whole.

In this regard, as shown in FIG. 22 , in the temperature control device 1 for an injection molding machine according to a modified embodiment of the present invention, the first supply mechanism 511 is spaced apart from the cover part 4 . Since the cooling gas is injected into the first temperature control area TA1 through the first connection mechanism 611, the first supply mechanism 511 is connected to the purge cover 400 (shown by a double-dashed line). It can be installed in a location where there is no interference. Since the first connection mechanism 611 is also implemented in a smaller size than the first supply mechanism 511 , it does not interfere with the purge cover 400 .
