Plastic toy mold capable of oscillating and eliminating bubbles by utilizing acoustic wave transmission

Abstract

The invention discloses a plastic toy mold capable of oscillating and eliminating bubbles by utilizing acoustic wave transmission. The plastic toy mold structurally comprises a positioning mold, an ejection rod, a sleeve hole, a mold, a movable mold, a sleeve rod and an injection molding hole. The plastic toy mold disclosed by the invention has the beneficial effects that oscillation acoustic waves with high frequency is generated by utilizing a movable rod under the action of high-speed rotation and collision of a rapping rod; a medium through which the acoustic waves can penetrate is utilized and the bubbles in plastic fluid are oscillated and eliminated, so that conditions that the density of molded plastic is not thick and the surface is relatively rough are avoided; when a child playsa toy, the child is easily cut; the acoustic waves have a reflection characteristic, and the acoustic waves, which are generated by colliding the rapping rod and the movable rod and are diffused outward, are separated through a plurality of grooves formed in the surface of an inner side wall of a reflection plate and are reflected, so that the reduction of acoustic energy is reduced and a great quantity of the acoustic waves can be utilized; the plastic fluid is efficiently oscillated so that the bubbles in the plastic fluid are oscillated and eliminated and the thickness is compacted; and atemperature detector in a temperature-sensing shell is set to constant temperature and electric power is provided for an acoustic wave penetration mechanism.

Description

technical field [0001] The invention relates to the field of plastic toy manufacturing equipment, more precisely, it is a plastic toy mold that uses sound waves to propagate air bubbles and flatten them. Background technique [0002] There are many toys of different shapes on the market, which have an irresistible allure for children. More and more families with babies will buy different toys for their babies to play with. Therefore, people's choices on the materials of toys are very Compared with toys made of other materials on the market, plastic toys are more suitable for young children. Therefore, most of the toys on the market are made of plastic toys. The production of such toys is through the use of mold equipment to heat The molten plastic fluid is cooled, and then the required toys are formed. However, the air bag provided on the edge of the mold of this injection molding equipment cannot completely exhaust the air bubbles in the plastic fluid, which leads to the to...

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a plastic toy mold that uses sound waves to propagate air bubbles to flatten, so as to solve the problem of air bubbles existing in the plastic fluid caused by the air bag provided on the edge of the mold in the injection molding equipment of the prior art. Complete exhaust cannot be carried out, resulting in some pores visible to the naked eye on the surface of the toy plastic after cooling and molding, resulting in a rough surface of the molded plastic toy, and because the skin and flesh of children are relatively delicate, it is easy to cause children to be caught. At the same time, the air bubbles inside the plastic fluid are weaker than water and the density is relatively turbid, resulting in plastic toys with multiple air holes inside, not thick enough and not enough in weight, making the quality poor, so for some large For plastic toys, it will cause some inevitable harm to children.
