Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the specific content of the novelty of the present invention will be further described.

[0026] The rapid manufacturing process of the rotomolding machine mold comprises the following steps:

[0027] A. Model generation: According to the shape of the upper and lower molds of the rotational molding machine mold, use a three-dimensional CAD system to design the contour models of the upper and lower molds of the rotational molding machine mold, and add flanges to the edges of the upper and lower mold contour models 7 model, the model of positioning pin or tongue and groove 6 is set on the flange 7, and the model of the boss 3 used to form the measurement pressure relief hole is set on the upper mold contour model; finally, the three-dimensional CAD model of the rotomolding machine mold is generated ;

[0028] B. Adjusting parameters: According to the requirements for the lines 11 used to increase the frictional force on the...

Abstract

The invention discloses a quick manufacturing process of a rotational moulding machine die. The process comprises the following steps of: obtaining a surface area; selecting a material; selecting a thickness; manufacturing lines and controlling; manufacturing a measurement pressure relief hole; manufacturing a flange edge; manufacturing a die frame; and manufacturing a locking device, wherein a numerical control sheet metal incremental forming technology is utilized as a core for manufacturing the die to realize most mechanical characteristics of the die. Compared to casting, the direct sheet mould-free forming does not need to consider the magnification ratio, a die is directly produced according to a required size of a plastic product, and the surface area is obtained through a numerical control mould-free forming device and used as an inventory reference of a rotational moulding raw material. Because most steps in the manufacturing process of the rotational moulding machine die can be finished by utilizing one numerical control mould-free forming device, the automation, the precision, the efficiency and the flexible level in the manufacturing process are greatly improved, and the cost of the manufacturing process is obviously lower than that of a traditional manufacturing process.

Description

technical field [0001] The invention relates to a rapid manufacturing process of molds for rotomolding machines. Specifically, it utilizes the numerical control progressive forming technology of metal plates to quickly manufacture various metal plates with a thickness of less than 4mm into rotomolding molds required by rotomolding machines. technical background [0002] At present, the known manufacturing methods of rotomolding molds mainly adopt three types of steel plate welding molds, aluminum alloy welding molds and aluminum alloy casting molds, among which the application of aluminum alloy casting molds can best guarantee the quality of rotational molding products. However, the aluminum alloy casting mold has the following disadvantages: the process is cumbersome, difficult and costly. The process includes wooden mold making, manual assembly of wooden molds, vacuum gravity casting, mold CNC machining, EDM, fitter polishing, and making leather patterns. The quality is d...
