[0033] Reference Figure 1 The present invention discloses a method and system for automatically calculating the price of vacuum mold re-casting, comprising the following steps:

[0034] S1: Establish the vacuum mold price calculation formula A = X + Y + Z * X2 In the above formula:

[0035] In the above, A represents the total price, X represents the prototype price, Y represents the mold price, Z represents the unit price of the product, and X2 represents the number of products;

[0036] X=(X1*((((X2 / X3)-1)*L1)+1)*L2+(X2 / X3*X4 / L3+L4)*L5)*L6

[0037] In the above formula, 1 represents the constant in the prototype price formula, X1 is the product volume, which is obtained by the system from the 3D drawing information; X2 is the number of products, which is determined by the customer's order; X3 is the output of a single mold, which is set by the quotation engineer based on the material and complexity of the workpiece. A mold is scrapped after producing X3 products, so it is also called the life of a single mold; L1 is the scrap rate of the 3D printing process, and L1 is preferably 0.33; L2 is the cost per unit volume in the 3D printing process, in cubic centimeters, and is preferably 6.27714RMB / cm 3 ; X4 is the surface area of ​​the product, in mm 2 , L3 is the surface area that can be processed in 1 hour. Our company prefers to set L3 to 20000, which means that 20000mm can be processed in 1 hour. 2 surface area; L4 is the minimum processing time, L4 is preferably 2 hours, because if the time is too low, there will be no profit. In the production process, it is inevitable to encounter problems such as mold repair and correction. If the production time is too low, the proportion of the above time will be magnified, resulting in no profit; L5 is the labor cost of the prototype, L5 is preferably 50 yuan, L6 is a constant for the sales price of the prototype, L6 is 2,

[0038] In the above, L1, L2, L3, L4, L5, and L6 are already built into the system and do not need to be filled in by the quotation engineer. Therefore, only X2 and X3 need to be entered to calculate the prototype price.

[0039] The result of X2 / X3 calculation is the number of molds required to process the product. If it is less than 1

[0040] are rounded up to 1.

[0041] The result of ((X2 / X3)-1)*0.33 is the number of additional 3D prints.

[0042] The result of ((X2 / X3)-1)*0.33+1 is the total number of 3D prints.

[0049] The result of ((X2 / X3)*X4 / 20000+2)*50 is the total processing cost of the 3D printing surface area.

[0050] In order to ensure profit, the 3D printing cost plus the 3D printing surface area processing cost needs to be multiplied by the constant L6 to obtain the prototype sales price X.

[0051] Y=(((Y1+K1)*(Y2+K1)*(Y3+K1)) / 1000000*(X2 / X3)*K2*K3*K4+((((Y1+K1)*(Y2+K1)*(Y3+K1)) / 1000000) / K5+K6)*(X2 / X3)*K7)*K8

[0053] In the above, K1, K2, K3, K4, K5, K6, K7, and K8 are already built into the system and do not need to be filled in by the quotation engineer. Y1, Y2, and Y3 are obtained by the system from the 3D drawing information, so only X2 and X3 need to be entered to calculate the mold price.

[0054] (Y1+60)*(Y2+60)*(Y3+60) / 1000000 is the volume of silica gel.

[0055] Volume, in cubic decimeters (dm) 3 ,

[0064] ((((Y1+60)*(Y2+60)*(Y3+60)) / 1000000) / 3+3)*(X2 / X3)*50

[0065] The result is the labor cost of handling the silicone mold.

[0066] In order to ensure profits, the model price needs to be multiplied by the constant K8 as the sales price. The reason is the same as that of the prototype, so it will not be elaborated.

X1 is obtained by the system from the 3D drawing information, so you only need to enter X2 and X3, and select the material to calculate the unit price of the product.

[0069] The calculation result of X2+T1 is the quantity of products including 1 scrapped product.

[0070] The calculation result of X1*(X2+T1) is the volume of product including scrapped product.

[0083] *(X2+T1) / 1000) / T6))*T7+X2*T2*T8)*2)The calculated value is the total cost of product material usage + labor cost + other consumables cost.

[0084] (X1*(X2+1)) / 1000*T2 calculates the weight of materials required for all products

[0085] However, we all know that in actual production, the more products are produced, the cheaper the unit price is. Therefore, four unit price ranges are set in this application, and the total price is calculated by the required number of molds corresponding to different unit prices:

[0086] Only one mold is needed to produce the number of products, and the total price is: Z*X2;

[0087] Two molds are needed to produce the product quantity. The discount factor of the second mold is R1, and its total price is Z*X3+(X2-X3)*Z*R1. If this total price is divided by the product quantity X2, its average unit price can be obtained.

[0088] Three molds are needed to produce the number of products. The discount coefficient of the third mold is R2, and the total price is Z*X3+Z*X3*R1+(X2-2*X3)*Z*R2. If this total price is divided by the number of products X2, the average unit price can be obtained.

[0089] If four or more molds are needed to produce the product quantity, the discount factor for the fourth or more molds is R3, and the total price is: Z*X3+Z*X3*R1+Z*X3*R2+(X2-3*X3)*Z*R3. If this total price is divided by the product quantity X2, the average unit price can be obtained;

[0090] S2: Establish a vacuum mold remodeling price calculation system according to the above vacuum mold remodeling price calculation formula. The vacuum mold remodeling price calculation system is referred to as the system in this application.

[0091] The system includes a product quantity module, a material module, and a mold production module. Therefore, after the quotation engineer uploads the 3D drawing attached to the inquiry order, the system will automatically read the 3D drawing information, which includes the length, width, height, volume, and surface area of ​​the workpiece. The quotation engineer only needs to fill in the quantity in the product quantity module and the material in the material module, and fill in the production of a single mold in the mold production module after analyzing the workpiece material and complexity. The system can automatically calculate the prototype price, mold price, product unit price and form the total price of the inquiry order.

[0092] The above is a detailed introduction to a method and system for automatically calculating the price of vacuum molding provided by an embodiment of the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the present invention, there will be changes in the specific implementation method and application scope.
