Embodiment Construction
[0009] Preferred embodiments of the present invention will be described in detail below.
[0010] A process for improving glue overflow on the hot-melt surface of an oil pot, comprising the following steps, such as figure 1 As shown, the details are as follows: 1) The cavity structure design and manufacture of the hot-melt surface of the injection mold. ) design and manufacture of injection molds to produce a large number of oil pots, and then these oil pots are melted together in pairs. Close together to complete product hot-melting; 3) Check whether the products after hot-melting in the warehouse need to be checked whether they are qualified, and put into the warehouse after the inspection is correct.
[0011] Wherein, the oblique angle of the melt glue portion of the hot-melt surface is 30° or 45°, such as figure 2 As shown, these two angles are the best angles we found and concluded through many experiments, other angles are also possible, but the effect is not so obvio...

The invention discloses an oiler hot melting face glue overflowing improving process. The oiler hot melting face glue overflowing improving process comprises the following steps that (1) during injection mold molding hot melting face mold cavity structure design and manufacturing and injection mold hot melting face mold cavity design, hot melting face glue melting components are designed into oblique angles; (2) according to heat melting treatment, an injection mold designed and manufactured in the step (1) is used for producing a large number of oilers, then every two of the oilers are combined through hot melting, hot melting faces of the oilers are firstly heated through heating equipment during hot melting, the hot melting faces are aligned and tightly abutted against with each other after heating, and product hot melting is completed; and (3) examination and storage are carried out, wherein whether products obtained after hot melting are qualified or not needs to be examined, storage is carried out after examination is without error and the product are qualified, the melting faces are designed to be oblique angles, water shrinkage is not prone to occurrence during injection molding, welding faces are more even and higher in strength, the glue overflowing amount is small, the appearance is attractive, an oblique angle mold cavity facilitates demolding and air exhausting, the service life of the mold is long, the using cost is low, and operation and use are more convenient.
Description
technical field [0001] The invention belongs to the field of hot-melt technology, and in particular relates to an improved technology for overflowing glue on the hot-melt surface of an oil pot. Background technique [0002] The hot-melt surface of the injection mold of the oil pot is at right angles, and glue overflow will occur during the hot-melt process. The right-angle structure can meet certain hot-melt requirements, but there are many defects. Wide, the glue overflows after welding, which greatly affects the appearance, and the glue on the hot-melt surface is thicker, the injection shrinkage is serious, and a depression will be formed in the middle, hot-melt welding will produce virtual welding, the welding strength is poor, and the right-angle structure is not good. It is beneficial to mold demoulding and exhaust, but the service life of the mold is short, the use cost is high, and the use is very inconvenient. Contents of the invention [0003] In order to solve t...
