Description
Technical Field
The utility model relates to an injection molding production field, more specifically say, it relates to a lower double-colored mould for production ruler of cost.
Background
The production and processing process of the injection molding part needs to use a mold. Wherein, some complicated castings need to use double-colored mould, and double-colored mould is two kinds of plastic material and moulds plastics on same injection molding machine, divides twice shaping, but the mould of product demolding once only.
Two-color film injection molding has some characteristics: the front mold A, B was shaped differently for each of the 1 products, and the rear mold was shaped identically for the A, B panels. After the front and back dies of the die are rotated 180 degrees around the center, they must be matched. During injection molding, the product formed by the first injection molding is generally slightly larger in size, so that the product can be pressed tightly with another male mold during the second injection molding, and the function of sealing glue is achieved. During the second injection molding, the plastic flow needs to be designed to avoid impacting the pattern of the product which is molded at the first time, so as to avoid the deformation of the glue position. Before the A, B die plates are closed, the problem that the front die slide block or the inclined top is reset to crush the product is avoided. Because the soft rubber is easy to deform, the hard rubber part of the product is firstly injection-molded and then the soft rubber part of the product is injection-molded in the general condition during injection molding.
There is a two-color mold for injection molding ruler in the prior art, which comprises a main body part and a transparent part, wherein the main body part has some figures in the center, scales are arranged on two sides, and the transparent part covers the main body part. The technical scheme of the mould for producing the ruler has the key points that the cavities formed by the front film A plate and the rear film A, B plate are used for injection molding of the main body part of the ruler, and the cavities formed by the front film B plate and the rear film A, B plate are used for injection molding of the transparent part of the ruler. The ruler with the technical scheme can be well produced, but the graph part in the middle of the main body part of the ruler is rough, the requirement on the precision of a front mould A plate to be machined is low, the scale part of the main body part is fine, and the requirement on the precision of the front mould A plate to be machined is high. This arrangement requires the front mold a plate to be shaped to both the scale portion and the middle pattern portion. Above-mentioned technical scheme has a great deal of inconvenience, and several kinds can be realized just to the processing sword needs to be changed, has also correspondingly wholly improved to the board that can process the accurate shape of scale moreover to the requirement of board material, and then has caused manufacturing cost's increase.
Therefore, it is necessary to design a low-cost two-color mold for producing a ruler to overcome the above problems.
