Broom head, mold for preparing broom head and broom head processing technology

Abstract

The invention relates to a broom head, a mould for preparing the broom head and a method for processing the broom head by adopting the mould, and belongs to the technical field of processing of the broom heads. A processing mould of the broom head comprises an upper mould and a lower mould, wherein the upper mould comprises a mould body and an injection hole formed in the mould body and a plurality of pairs of main moulds and secondary moulds; the main moulds and secondary moulds comprise channels and grooves the depths of which are gradually changed, the plurality of channels are parallelly arranged on one sides of the grooves the depths of which are smaller, and the channels are connected with the grooves; the injection hole is connected with the grooves through a flowing channel, the depth of the flowing channel is less than those of the grooves; the lower mould has no injection holes, and the other structures of the lower mould are as the same as the structures of the upper mould. Due to the adoption of the technical scheme, the integral broom head can be processed, and the mould and the processing technology have the advantages of high yield, convenience and rapidness in operation, low cost, and the like.

Description

technical field [0001] The invention relates to a broom head, a mold for preparing the broom head and a method for processing the broom head by using the mold, belonging to the technical field of broom head processing. Background technique [0002] The broom head of the sweeper mainly includes two parts, the wire sweeper and the handle head. In the prior art, the processing flow of the broom head is mainly as follows: adding plastic raw materials into the hopper of the extruder, melting and drawing in the extruder, and obtaining the wire sweeper. , After brushing and cooling, place it on the edge of the handle mold of the injection molding machine, inject molten plastic raw materials, and cool it down. Adopt this technology to carry out the processing of broom head, its defect is: [0003] First, at least two sets of equipment, an extruder and an injection molding machine, are used in the processing process to process the wire sweeping and the head respectively. The process...

AI Technical Summary

Problems solved by technology

[0003] First, at least two sets of equipment, an extruder and an injection molding machine, are used in the processing process to process the wire sweeping and the head respectively. The processing process is relatively cumbersome and the processing technology is relatively complicated. At the same time, the cost of the two devices is relatively high;

[0004] Second, in the process of wire sweeping processing to the handle head, after the formed wire sweeps are arranged, they are bundled into the mold of the handle head, and under a certain pressure, the wire sweeps are spread flat on the edge of the handle mold. It is impossible to ensure the uniform distribution of the wires on the handlebar. At the same time, because the wires are superimposed, the wires located on the periphery can be firmly bonded to the melt in the mold of the handle, while the wires located in the middle of the whole bundle The broom wire may not be able to touch the melt injected into the handle mold by the injection system of the injection molding machine, and after molding, the broom wire in the middle will fall off, and when the shedding reaches a certain number, it will affect the entire broom head Therefore, the yield and the quality of the broom head cannot be guaranteed

[0005] Third, the conventional broom wire is made of all plastic material, simple in structure, poor in wear resistance, and short in service life. Therefore, in the process of use, the cleaning ability is weak, and the broom head must be replaced frequently. Frequent replacement work not only increases the workload of the operator Labor intensity, and the cost also increases
