Embodiment Construction

[0017] The utility model relates to a permeable plastic gourd model, which is made of plastic, and the whole model is composed of model petals which are divided into several parts in the vertical direction. Ventilation aperture 8 is arranged on model model valve. There is a ventilating hole with a diameter of 0.2-0.5mm at every 3-5mm on the surface of the model flap (see figure 1 part of the magnification).

[0018] Such as figure 1 , 2 Its overall model of the shown plastic gourd model is made up of model petals 1,2 that are divided into two parts in the vertical direction.

[0019] Such as image 3 , 4 Its overall model of the shown plastic gourd model is made up of model petals 3, 4, 5, 6 that are divided into four parts in the vertical direction. One of the model petals has a gourd model bottom 7 (see image 3 ).

[0020] The plastic used can use transparent plastic or opaque plastic.

[0021] This gourd model replaces the non-renewable plaster material with a ren...

Abstract

The invention relates to a ventilated plastic calabash master die which is made of plastics, wherein the integrated master die comprises master die vanes which are divided into several parts in the vertical direction, small ventilated holes are formed on the master die vanes, and transparent plastics can be used. Compared with the currently used gypsum master die, the plastic master die has the absolute advantages that plastic materials can be recycled but gypsum can not be recycled; the plastic master die has light weight and high strength and can be used for manufacturing finer patterns; the plastic master die has smooth surface and fine texture and can not generate bubbles; the plastic master die can prevent water and transmit light; the plastic master die can be repeatedly used for many times, can be scrubbed and can be sterilized easily; and the plastic master die has skillful manufacture and accurate positioning and can be opened easily. The transparent plastic master die can be used for observing growing process of the calabash, finding and removing the calabash of poor growth in time, correcting the culture process easily, summarizing the culture experience, increasing the pleasure of visibility, and manufacturing more three-dimensional, more beautiful and finer master die of the calabash.

Description

technical field [0001] The invention belongs to a special-purpose mold, in particular to a gas-permeable plastic gourd model. Background technique [0002] Chinese model gourds have a long history and are deeply loved by the public. However, due to the limitation of making model materials and production techniques, there are relatively few producers, and there are few finished products, fewer high-quality products, and the cost of finished products is very high. Acceptable, it can only be appreciated from a distance and cannot be played at close range. It takes more than ten days for the plaster model to be ready for use. And when making the gypsum model, due to the characteristics of gypsum itself, when casting and making the gypsum model. There will be a lot of bubbles inside the gypsum model, so-called dark bubbles, and it is not easy to be found, especially the dark bubbles immediately below the surface of the gypsum model, which are blocked by the thin gypsum skin on ...
