Problems solved by technology

The previous molding method was to use almost one set of molds to correspond to only one specification product. The factory had to prepare many molds, which required large investment and high cost.
The previous hot pressing method for vulcanization molding is to use steam hot pressing resistance conduction hot pressing. The disadvantages are: 1. The hot pressing of various parts of the molded rubber is uneven, resulting in low dimensional accuracy of the product and difficult quality control; 2. Hot pressing The vulcanization time is long, the effective heat utilization is less, and a lot of heat is dissipated into the ambient air; 3. The production efficiency is low and the operation intensity is high, which cannot ensure safe production

Embodiment Construction

[0010] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0011] The precision engineering plastic product induction hot-press molding die that the present invention relates to, such as figure 1 As shown, it consists of indenter 1, guide cylinder 2, left splint 3, induction coil 4, core 7, main cylinder 8, left screw 9, coupling 10, right screw 11, and right splint 12. There is a first taper hole 13 at the bottom of the indenter 1 . There is a second tapered hole 14 at the bottom of the main cylinder. The mold core 7 is automatically centered and positioned through the second tapered hole 14 and the first tapered hole 13 . The lower end surface of the indenter 1 is pressed against the upper end surface of the workpiece, the outer circumferential surface of the indenter 1 and the inner surface of the guide cylinder 2 are in clearance fit, and the indenter 1 can slide up and down in the guide cylinder 2 to adapt to ...

Abstract

The induced hot shaping mould for precise engineering plastic product comprises pressure head (1) that can slide up and down in guide cartridge (2) to fit work piece length, left clamp (3), induction coil (4) in main cartridge (8) to heat press evenly by high, middle and power frequency, mould core (7), left screw (9), coupling (10), right screw (11), and right clamp (12). This invention can fit to plastic products of a plurality of sizes, needs less energy, and fits particularly to process for new-type complex material.

Description

technical field [0001] The invention belongs to the technical field of precision molding processing of engineering plastic products, and in particular relates to a precision molding processing mold suitable for new engineering composite material products such as water-lubricated composite rubber bearings, high-performance seals, and high-elastic couplings. technical background [0002] At present, new engineering composite products such as water-lubricated composite rubber bearings, high-performance seals, and high-elastic couplings are widely used, requiring many varieties and specifications to meet the actual needs of engineering applications and industrial development. A specification corresponds to a different combination of outer diameter, inner diameter, and length. The previous molding method was to use almost one set of molds to only correspond to one specification product. The factory had to prepare many molds, which required large investment and high cost. The pre...
