Embodiment Construction

[0042] The mold for making unsaturated polyester resin products of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so as to help understand the content of the present invention.

[0043] like figure 1 , Figure 4 and Figure 8 As shown, taking the production of unsaturated polyester resin cup products as an example, the mold mainly consists of three parts, namely:

[0044] (1) The mold base 1 processed by Saigang material is in the shape of three steps, and the steps gradually become larger from top to bottom, that is, figure 2 The shown intermediate step 1b is larger in plane size than the top step 1a, and the lower step 1c is larger than the intermediate step 1b. The specific size of the steps depends on the specifications of the products produced;

[0045] (2) The inner mold barrel 2 is made of resin material, and the lower end is surrounded by the top step of the mold base 1 to form a str...

Abstract

The invention discloses a mold for manufacturing unsaturated polyester resin products. The mold is characterized by comprising a mold base, an inner mold tube, an outer mold tube and a mold cavity, wherein the mold base is in a shape of at least three steps gradually enlarged from top to bottom, the inner mold tube is made of resin materials or soft metal, the lower end part of the inner mold tube is surrounded and sheathed on the first step of the mold base for forming a straight tubular inner mold, the outer mold tube is made of resin materials or soft metal, the lower end part of the outer mold tube is surrounded and sheathed on the step arranged under the step sheathed by the inner mold tube for forming a straight tubular outer mold, the mold cavity forms a casting mold cavity with an annular space surrounded by the inner mold tube, the outer mold tube and the mold base, and the upper part of the annular space is provided with an opening. The mold has the advantages that the structure is simple, the weight is light, the cost is low, the product dimension precision is high, the mold can be used for making standard perfect round products and polygonal products, and the surfaces of manufactured blank products are clean and smooth.

Description

technical field [0001] The invention relates to a mold, especially a mold for making unsaturated polyester resin bathroom products. The mold is simple to make and use, small in size, light in weight and low in cost, and is suitable for producing perfectly circular or polygonal products. Background technique [0002] Sanitary products made of unsaturated polyester resin have divided the market of traditional ceramics, hardware and other sanitary products with their unique shapes and novel styles. In order to obtain a better product surface finish or to facilitate demoulding, sanitary products made of unsaturated polyester resin are usually made of a silicone mold, but the defects of the silicone mold itself lead to unsaturated polyester The production of ester resin bathroom products encountered two bottlenecks, mainly as follows: [0003] First, the characteristics of the production process of silicon mold removal to make sanitary products are that the molds include silicon...
