Problems solved by technology

[0002] Existing energy-saving lamp molds generally use metal molds, which can only make conical or columnar spiral lamps. However, for spiral lamps with small diameters at both ends and large diameters in the middle, such as spherical, duck-egg-shaped, and lantern-shaped lamps, metal The mold cannot be demolded

Embodiment Construction

[0011] Take 45# steel with appropriate diameter and length and process it on a lathe into a male mold for lamp tubes, then use the processed male mold to cast it into a female mold, and then cut it into two halves by wire cutting according to the center line of the female mold. And make the positioning pins to fix the two halves of the mold; use a lathe to process the mold core according to the size, and drill holes on the processed mold core according to the size to install anti-slip blocking blocks and pin keys, and then weld the R groove on the top of the mold core Fix the rod; crush the refractory mud and screen it with a 200-mesh fine sieve; add water to the screened refractory mud and stir it into a moderately soft and hard mold material, and put the mold material on the mold core and squeeze it tightly before putting it into the processed In the female mold, lightly tap the female mold with a wooden or rubber hammer to make the female mold closely fit, and then remove th...

Abstract

The invention relates to a technology for manufacturing molds for producing a spiral energy-saving lamp with the large middle and two small ends, and belongs to the technical field of energy-saving lamps. The molds for producing the spiral energy-saving lamp with the large middle and the two small ends are obtained. Through a specific process, the male mold of a lamp tube is made of metal materials, and the female mold is formed through casting; and a muddy male mold is made of refractory mortar mold materials screened by a 200-mesh fine screen. The molds can be decomposed, and therefore mold stripping is facilitated. The method has the advantages that the technology is advanced, mold stripping is convenient, and the mold materials can be repeatedly used.

Description

technical field [0001] The invention relates to a mold making technology for producing a spiral energy-saving lamp with a large center and small ends, and belongs to the technical field of energy-saving lamp manufacturing. Background technique [0002] Existing energy-saving lamp molds generally use metal molds, which can only make conical or columnar spiral lamps. However, for spiral lamps with small diameters at both ends and large diameters in the middle, such as spherical, duck-egg-shaped, and lantern-shaped lamps, metal The mold cannot be demolded. However, in people's daily life, there are a large number of places where such lamps need to be produced, such as spherical lamps and oval lamps in street lamps. Therefore, the problem of making molds that are easy to release is the key to the production of the above products. Contents of the invention [0003] The object of the present invention is to provide a mold making technology for producing spiral energy-savin...
