Embodiment Construction

[0016] figure 1 Shown is the schematic diagram of the forming equipment of the prosthetic receiving cavity and the inner lining forming method. The shape of the prosthetic receiving cavity and the inner lining into the cylinder of the present invention is the same, but one is hard plastic and the other is soft plastic. It is to first press the plastic into a cylindrical blank 3 to be made into another part, and then put it into a special oven and heat it to the softening temperature of the plastic. The softened plastic tube blank 3 is closely attached to the surface of the male mold 4. After cooling, it is processed into a finished product shape according to the drawing. The production process is as follows:

[0017] 1). Select the appropriate tube blank 3 (such as image 3 shown);

[0018] 2). Cut a section of cotton yarn sleeve to cover the edge 2 of the bottom blank 3 of the tube, then clamp the special clamp 6 on both sides of the edge 2, and press it with fixing screws;...

Abstract

The formatino process for plastic artificial limb receiving chamber and inner lining tube includes roasting the blank to soften, jacketing to the male mold in vacuum table, vacuum pumping to product inner and outer pressure difference for pressurizing the plastic blank to the male mold, cooling, taking down the blank in the male mold, and further processing. The artificial limb receiving chamber and inner lining tube are smooth, bright and fine and the formation process is simple and low in cost.

Description

technical field [0001] The invention belongs to the technical scope of thermoplastic forming, and particularly relates to a prosthetic receiving cavity and a method for forming an inner lining into a cylinder for artificial limbs of disabled persons. Background technique [0002] In the prosthetic manufacturing industry, the production of lower limb prosthetic receptacles is currently a commonly used thermosetting resin material in China. The process is cumbersome, time-consuming, labor-intensive, consumables are many, and the production cost is high, which increases the economic burden of the disabled. The pungent odor produced during the production process is not good for the health of the production staff. At present, prostheses in developed countries are generally made of plastic and are formed by thermoplastic. The inner lining of the prosthetic receiving cavity is made of foam board, which is not wear-resistant and easy to age, and needs to be replaced after a period...
