Although the above-mentioned creation can achieve its creation purpose, the following defects will occur in the manufacturing process:

Because the upper and lower dies of the earth and sand are all produced in person by master-level personnel, especially, how to evenly distribute several cushion blocks one by one and place them at the predetermined positions of the earth and sand lower die for the first time? How to place the top plane of the sand core inner mold at the top of the pad for the first time and make the sand core inner mold evenly located in the predetermined position of the soil sand lower mold? How to evenly distribute several of these pads one by one and place them on the bottom plane of the sand core inner mold for the second time? All of them need to be placed by experienced masters. In this way, not only is the production capacity limited due to too many times of placing work one by one, so that it is impossible to greatly increase its output, but at the same time , the salaries of experienced masters are relatively high, and the The unit price of its output is high, and the lack of market competitiveness is a major problem.

As mentioned above, in order to solve the problem that it is difficult to hire experienced masters, the industry often hires a large number of foreign workers for accompanying training. However, during the accompanying training process, the yield rate will often decline significantly, and the production capacity will be greatly reduced. Its another big problem.

As mentioned above, when the poured hot-melt copper alloy liquid flows and touches the Styrofoam pad, the pad will be melted quickly, and the flowing hot-melt copper alloy liquid will be pushed into the sand core. The mold moves at the predetermined position of the soil-sand upper and lower molds, so that the inner mold of the sand core will deviate and touch the inner wall surface of the predetermined position of the soil-sand upper and lower molds. As a result, the breakage rate of the furnace head produced by it is greatly It is another major problem to greatly reduce its production capacity.

Therefore, how to develop a technology that can reduce the over-reliance on master-level personnel, reduce costs, and improve yield, production capacity, and competitiveness is a technical issue that the industry needs to solve first.

The main content of the manufacturing method of the gas copper burner head and the sand core inner mold used for the manufacture of the gas copper burner head of the present invention is to provide a positioning groove by first bonding the copper gaskets to the base of the sand core inner mold, So that the copper gasket can be clamped and supported between the fixed groove at the predetermined position of the metal upper and lower molds and the positioning groove of the sand core inner mold, so that the sand core inner mold can be suspended and fixed on the metal upper and lower molds (A) material preparation processing; (B) bonding processing; (C) spraying processing; (D) placing and closing mold processing; (E) pouring and pressing processing; (F) cooling sampling processing (G) vibration cleaning processing; (H) supplementary processing; (I) polishing processing; (J) hole processing; (K) smoothing processing; Copper burner finished products of mixing tube and flame hole. In this way, it can not only replace professional staff by hiring non-professional In order to greatly reduce the over-reliance on master-level personnel and reduce their labor costs, it can also reduce the technical bottleneck of the sunset industry, so that new personnel can be reinjected to activate or extend the life of the generation, and at the same time , It can also greatly increase production capacity and yield, and then greatly improve its market competitiveness.
