Problems solved by technology

However, due to the good thermal stability of silica gel, it can only be manufactured at high temperature. After the processing is completed, due to the high temperature of silica gel processing, the parts cannot be taken out in time, leaving the machine empty and greatly reducing work efficiency.

Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and structural, method, or functional changes made by those skilled in the art according to these embodiments are included within the protection scope of the present invention.

[0025] like Figure 1 to Figure 3 As shown, the present invention discloses a high-precision silicone injection mold, which at least includes an upper template 1 and a lower template 2. There is a groove 21 on the lower template 2, and a mold core 22 is arranged in the groove 21. The upper surface of the mold core 22 is at the same level as the upper surface of the lower template 2, and a first positioning mechanism 23 is provided between the mold core 22 and the lower template 2, and the first positioning mechanism 23 includes a fixed The three first protrusions 28 on the groove 21 of the lower...

Abstract

The invention discloses a high-precision silicone injection mold, which at least includes an upper template and a lower template. There is a groove on the lower template, a mold core is arranged in the groove, and a The first positioning mechanism; the mold core is provided with a cavity for part molding, and the upper template is provided with a raw material tank for holding injection molding raw materials, and the raw material tank is arranged with the flow channel in the upper template It communicates with the mold cavity, and the raw material trough, the runner and the mold cavity cooperate to complete the injection molding of the parts, and a second positioning mechanism is also provided between the lower mold plate and the upper mold plate, and the upper mold plate There is also a pressing mechanism for pressing the raw material in the raw material tank to the flow channel. The present invention is mainly embodied in that the phenomenon that the inner hole of the product is blocked by the burr of the parting line is avoided, and at the same time, the processed and formed parts can be taken out by the manipulator in time, which greatly improves the working efficiency.

Description

technical field [0001] The invention relates to the field of injection molding processing, in particular to a high-precision silicone injection mold. Background technique [0002] Because silicone rubber materials have good oil resistance and solvent resistance, as well as excellent ductility and stretch resistance, they are widely used in the field of mechanical equipment, especially as seals in devices. . [0003] However, due to the particularity of injection molding, processing companies generally use the same molds as other materials when processing silicone rubber parts. However, due to the good thermal stability of silica gel, it can only be manufactured at high temperature. After the processing is completed, due to the high temperature of silica gel processing, the parts cannot be taken out in time, leaving the machine empty and greatly reducing work efficiency. [0004] To sum up, how to quickly take out the processed and shaped silicone rubber parts has become an...
