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 silica gel injection mould at least comprising an upper mould plate and a lower mould plate. A groove is formed in the lower mould plate. A mould core is arranged in the groove. A first positioning mechanism is arranged between the mould core and the lower mould plate. A mould cavity used for moulding of a part is formed in the mould core. A raw material groove for containing injection moulding raw materials is formed in the upper mould plate and communicates with the mould cavity by means of flow channels in the upper mould plate. Injection moulding of the part is completed by matching of the raw material groove, the flow channels and the mould cavity. A second positioning mechanism is further arranged between the lower mould plate and the upper mould plate. A pressing mechanism for squeezing the raw materials in the raw material groove to the flow channels is further arranged on the upper mould plate. The high-precision silica gel injection mould mainly has the advantages that the blocking phenomenon, caused by the rough edge of a parting line, of inner holes of the product is avoided; and meanwhile, the machining-moulded part can be taken out timely through a manipulator, so that the working efficiency is improved to a great extent.

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...
