Basic knowledge of mould base

The mold base has a pre-forming device, a positioning device and an ejection device.

The general configuration is panel, A board (front template), B board (rear template), C board (square iron), bottom plate, thimble bottom plate, thimble bottom plate, guide post, back pin and other accessories.

Upper mold (front mold/master mold)

It is configured as an inner molded part or an original molded part.

Runner part (including hot nozzle, hot runner (pneumatic part), ordinary runner)

Cooling part (water hole)

Lower mold (rear mold/male mold)

It is configured as an inner molded part or an original molded part.

Push-out device (finished product push plate, thimble, cylinder needle, inclined top, etc.)

Cooling part (water hole)

Fixing device (support head, square iron and needle board guide edge, etc.)

Large nozzle mold base (also known as single parting surface mold base), the standard length and width dimensions are from 150mm*150mm (1515 series for short) to 600mm*800mm (6080 series for short), due to different A board, B board, and pusher board And the pallet combination is divided into four models: A, B, C, and D. Due to the different structure of the code mold, the mold base has three types of I-shaped mold (I type), straight mold (H type) and straight mold plus panel (T type), combining four types of A, B, C, and D. There are 12 different types and specifications of the standard large nozzle mold base, and the mold maker can configure different plate thickness combinations according to product requirements. Large nozzle mold (also known as two-plate mold): The runner and gate are designed on the same parting line and demolded together with the product. The design is simpler, the production cost and time are less, and it is widely accepted and used by mold makers, but The disadvantage is that the appearance of the product is more obvious at the nozzle position, and subsequent processing is required to separate the nozzle and the product.

Simplified nozzle (also known as double/multi-parting surface mold base) is a simplified version of the nozzle mold base. The standard length and width specifications are from 150mm*150mm (1515 series for short) to 500mm*700mm (5070 series for short), simplified Four sets of tie rods are missing for the type fine nozzle mold base, and the AB plate guide pillars are also changed to four sets of long guide pillars, extending from the nozzle plate to the square iron. The mold bases are divided into two types: F type and G type. F type has a nozzle push plate and G type does not. Since there is no push plate between the A plate and the B plate, there are only two types of A and C. In addition, there are only two types. There are two types of fonts (I type) and straight molds (H type). There are a total of 8 different models and specifications. The mold maker can configure different plate thickness combinations according to product requirements. Simplified nozzle mold (also known as three-plate mold): the function is similar to the nozzle mold base, the runner and the gate are not in the same parting line, the product is demolded in the parting line, and the nozzle material is additionally in the nozzle plate parting line Demoulding. The hesitant simplified nozzle has four sets of tie rods and guide bushes less, and the design space is larger, so it allows the existence of narrower dimensions such as 1515 and 2023, which makes the mold making more flexible. Since the product and the gate have been separated, the appearance is more It is good, and there is no need to increase the work of follow-up nozzle separation.
