Problems solved by technology
However, the general pressure of the blister mold is low, because too high suction will cause the surface of the product to be uneven, and even the product will be damaged during the stretching process, so the general blister product can only reach a depth of 50mm
[0005] In addition, the temperature of heated and softened plastic plates and sheets is generally low after being transported by the production line. The existing plastic molds cannot heat the plastic plates and sheets, and the temperature of the plastic plates, sheets and plastic molds is further reduced , which is not conducive to stretching; for plastic products with undercuts, the temperature after molding is low and it is not easy to demould

The invention discloses an improved coil mould, which comprises a mould body, wherein the mould body comprises a mould base, a frame arranged around the mould base, and cavities arranged on the mould base; the front side of the mould base is provided with a plurality of cavities and coils, the coils are arranged in the cavities, a bulge is arranged in the middle position of the bottom of each cavity, the edge of the bottom of each cavity is provided with a plurality of positioning grooves, the coils are sleeved with the bulges, a gap is arranged between each coil and the side wall of each cavity, and connectors at the bottoms of the coils are cooperatively connected with the positioning grooves; and the back side of the mould base is provided with a plurality of reverse bulges, the middle part of each reverse bulge is in an inwards concave structure, and the end surface of each bulge is provided with a plurality of lugs uniformly distributed along the edge of the end surface. The improved coil mould has the beneficial effects that the smoothness of a product surface is improved, the production efficiency and the rate of finished products can be improved by 20-25%, the cost is reduced, a sheet can be better stretched in production, the smoothness of the product surface and the qualified rate of products are improved, and the follow-up demoulding operation is convenient to carry out.
Description
technical field [0001] The invention relates to the field of moulds, in particular to a coil installation mould, which adopts a reverse mould. Background technique [0002] All kinds of tools and products we all use in daily production and daily life, ranging from the base from the machine device and the covering of the equipment equipment, to the small size of a screw, button and the shell of various household appliances, are all closely related to the molds. The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products. Due to the different materials, appearance, specifications and uses of various products, molds are divided into non-plastic molds such as casting molds, forging molds, die-casting molds, and stamping molds, as well as plastic molds. [0003] With the continuous improvement of engineering plastics in terms of strength and precision, the application range of pla...
