Problems solved by technology

That is to say, the focus of technology is to find ways to reduce the generation of mold scale. The existing technology lacks the collection of mold scale itself, and it is difficult to conduct research on injection molding process and material components through mold scale.

Embodiment

[0053] Such as Figure 1-Figure 3 As shown, the present embodiment provides an injection mold for mold scale collection, including a mold body, a mold cavity 4 for injection molding, a gate 3 for pouring a melt in the mold cavity 4 and a mold cavity for injection molding are provided in the mold body. Channel that directs the melt to gate 3. The mold body is also provided with a mold scale collection surface 5, and the mold scale collection surface 5 communicates with the mold cavity 4 to allow the gas to overflow from the mold cavity 4 to the mold scale collection surface 5, and the mold body is provided at a position corresponding to the mold scale collection surface 5 There are cooling liquid passages 6 for providing cooling to the mold deposit collecting surface 5 .

[0054] Among them, such as figure 2 , image 3 As shown, the mold body includes a fixed mold 11 and a movable mold 10 that are fastened together, and one or both of the movable mold 10 and the fixed mold ...

Abstract

The invention provides an injection molding die for die scale collection, a die scale collecting system and a die scale collecting method. The injection molding die comprises a die body, wherein a diecavity for injection molding, a pouring gate for pouring a melt into the die cavity and a runner for guiding the melt to the pouring gate are arranged in the die body. A die scale collecting surfaceis also arranged on the die body, and the die scale collecting surface communicates to the die cavity, so that gas overflows to the die scale collecting surface from the die cavity. A cooling liquid channel which plays a role of cooling the die scale collecting surface is also arranged in a position, corresponding to the die scale collecting surface, in the die body. Die scale can be collected bya true injection molding process, so that on the one hand, the die scale is highly associated to an actual injection molding process and product components, and on the other hand, the die can be directly used to collect the die scale on the produced die without arranging a special experimental device additionally, so that the structure is simplified, the cost is saved and a collected sample is further truer.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an injection mold for collecting mold scale, a system and a method for collecting mold scale. Background technique [0002] During the injection molding process, the melt enters the runner through the injection pressure, and then pours into the mold cavity. During the injection molding process, the volatilized gas in the melt usually forms part of the mold scale, which is usually caused by the composition of additives, thermal degradation, etc. On the one hand, it is necessary to minimize the generation of mold deposits during the injection molding process. On the other hand, the chemical composition of mold scale is very complex, and in fact, since mold scale is a material volatilized from the melt during injection molding, the physical and chemical properties of mold scale itself have an important impact on the injection molding process and product properties.
