Problems solved by technology

[0004] However, in the exhaust structure of the two-color mold, after the soft rubber is injected and molded, soft rubber burrs will be generated in the deep exhaust groove 11, which will block the exhaust groove 11 and need to be cleaned, and there are also cases of poor local exhaust. Bubbles, needle lines, and blackening of the joints will occur on the product, which will affect the production yield of the product

Embodiment Construction

[0017] see image 3 and Figure 4 shown, where image 3 A schematic diagram of the exhaust structure of the two-color mold of the present invention is shown, Figure 4 painted image 3 A partial enlargement of the .

[0018] In this embodiment, the exhaust structure of the two-color mold of the present invention is arranged on the slider 100 of the two-color mold. The exhaust structure has an exhaust surface 110, and the exhaust surface 110 is arranged on the side of the soft rubber position 101. At the broken part, the soft rubber position 101 is the position where the soft rubber is formed. The entire surface of the exhaust surface 110 is treated by embossing. After the embossing treatment, the exhaust surface 110 has concave and convex lines 111. The gas in the mold is discharged from the concave-convex lines 111 . Wherein, the embossing treatment refers to the use of chemicals to corrode the surface of the exhaust surface 110 to form concave and convex lines 111 .

Abstract

The invention relates to an exhaust structure, in particular to an exhaust structure of a double-color mold. The exhaust structure of the double-color mold is arranged on a sliding block of the double-color mold and is provided with an exhaust surface which is arranged at the abutting-breaking position of a soft glue station, the whole exhaust surface is treated in a texture mode, the exhaust surface is provided with concave-convex lines after texture treatment, and gas in the double-color mold is exhausted from the concave-convex lines. According to the exhaust structure of the double-color mold, the whole exhaust surface is subjected to texture treatment, a prior traditional electric discharging mode is replaced, local soft glue burrs are not generated, manpower for molding is saved, theexhaust effect of the whole exhaust surface is good, the soft glue gas trapping situation is relieved, and the production yield is increased.

Description

【Technical field】 [0001] The invention relates to an exhaust structure, in particular to an exhaust structure of a two-color mold. 【Background technique】 [0002] During injection molding of plastic products, gas is generated in the mold cavity with the injection of molten plastic liquid. The gas mainly includes: the air existing in the mold cavity and the gating system, and the moisture contained in the plastic raw materials evaporated at high temperature. The water vapor produced, the gas produced by the decomposition of plastic at high temperature and the gas produced by the volatilization of certain additives in plastic. During injection molding, if these gases cannot be discharged from the mold cavity in time, these gases will cause many problems such as gas lines, gas marks, cavities, burnt, and bubbles on the surface of the product when the product is molded. [0003] At present, in the two-color mold, when forming the hard rubber and then continuing to mold the soft...
