低壓灌注工藝及其模具的加工過程中，因為產品的結構問題，會導致模具的加工中出現很多的倒扣位置。如采用傳統的類比注塑模具的鑲件及滑塊設計模具，則模具的生產難度和工作量很大，精確度要求很高，同時制作費用和生產周期很多，在小批量生產中造成成本過大的問題，甚很多結構無法簡單通過一次成型加工，需要在模具成型后進行二次加工，步驟復雜。

In the process of low-pressure pouring process and mold processing, because of the product structure problems, there will be many reverse thread positions in the mold processing. For example, if the insert and slide block of the traditional analog injection mold are used to design the mold, the production difficulty and workload of the mold are very large, and the accuracy requirements are very high. At the same time, there are many production costs and production cycles, which cause the problem of excessive cost in small batch production. Even many structures cannot be simply processed by one-time molding, and they need to be processed again after the mold is formed. The steps are complex.

為了解決上述技術問題而提供一種能夠通過利用硅膠滑塊一次成型具有倒扣結構的產品的使用硅膠滑塊的低壓灌注模具的制作方法。一種使用硅膠滑塊的低壓灌注模具的制作方法，包括：

In order to solve the above technical problems, the invention provides a manufacturing method of a low-pressure pouring mold using a silica gel slider, which can form a product with an inverted structure by using a silica gel slider at one time. A method for manufacturing a low-pressure pouring mold using a silica gel slider, comprising:

S1、繪制原件圖檔：選擇待生產產品進行該產品結構的圖檔繪制；

S1. Drawing the original drawing file: select the product to be produced to draw the drawing file of the product structure;

S2、修訂模具原型圖檔：確定待生產產品的倒扣位置，并對S1中的圖檔進行修訂，在所述倒扣結構外側包覆長方體塊，且所述長方體塊與所述倒扣結構所處的待生產產品的表面貼合；

S2. Revise the mold prototype drawing file: determine the reverse position of the product to be produced, revise the drawing file in S1, wrap the rectangular block outside the reverse structure, and the rectangular block fits the surface of the product to be produced where the reverse structure is located;

S3、制作低壓模具原型：根據S2內修訂后的圖檔進行模具原型制作；

S3. Making low-pressure mold prototype: making mold prototype according to the revised drawings in S2;

S4、繪制倒扣結構圖檔：將S2內包覆的長方體塊繪制成單獨的圖檔；

S4. Draw the inverted buckle structure drawing file: draw the rectangular block covered in S2 into a separate drawing file;

S5、制作硅膠滑塊，根據S4內繪制的圖檔采用硅膠原料進行硅膠滑塊制作；

S5. Make silica gel slide block, and use silica gel raw materials to make silica gel slide block according to the drawings drawn in S4;

S6、整體模具制作，將S5中制作好的所有硅膠滑塊按照S1的圖檔設置在S3中的模具原型內；

S6. Overall mold making: set all silicone sliders made in S5 in the mold prototype in S3 according to the drawing files of S1;

S7、低壓模具灌注，對S6內制得的模具進行低壓灌注；

S7. Low pressure mold pouring: pour the mold made in S6 under low pressure;

S8、產品完成，取出S7內灌注后制得的整體模具，制得含有所述硅膠滑塊的半產品，將所述硅膠滑塊拆除，并對半產品進行精修處理，得到成品。

S8. After the product is completed, take out the overall mold made after pouring in S7, make the semi-product containing the silicone slider, remove the silicone slider, and refine the semi-product to obtain the finished product.

優選的，在S5中，所有所述硅膠滑塊均為左右開模結構。

Preferably, in S5, all the silicone sliders are left and right mold opening structures.

優選的，在S2中，所述倒扣結構外側包覆正方體塊。

Preferably, in S2, the outside of the buckle structure is coated with a cube block.

優選的，在S2中，所述長方體塊的尺寸均大于所述倒扣結構的尺寸。

Preferably, in S2, the size of the cuboid block is larger than the size of the inverted structure.

其中，所述倒扣結構為阻礙整體產品的開模方向的結構，即整體產品的開模方式為上下開模時，所述倒扣結構的開模方式為左右開模或前后開模。

Wherein, the reverse structure is a structure that hinders the mold opening direction of the overall product, that is, when the mold opening mode of the overall product is upper and lower mold opening, the mold opening mode of the reverse structure is left and right mold opening or front and rear mold opening.

山東快速成型廠家認為這里的發明提供的使用硅膠滑塊的低壓灌注模具的制作方法，通過將待成型產品的倒扣結構進行單獨成型支撐硅膠滑塊，并在制作原型時，將硅膠滑塊的尺寸置入原型內，使得在制作原型模具后，能夠將硅膠滑塊直接放置在原型模具內，進行統一灌注，并在原型模具開模后，取下硅膠滑塊，得到成品。

Shandong rapid prototyping manufacturers believe that the manufacturing method of the low-pressure pouring mold using silica gel slider provided by the invention here supports the silica gel slider by forming the inverted structure of the product to be formed separately, and when making the prototype, the size of the silica gel slider is placed in the prototype, so that after making the prototype mold, the silica gel slider can be directly placed in the prototype mold for unified pouring, and after the prototype mold is opened, Remove the silicone slider to get the finished product.
