Description
Technical Field
An injection molding mahjong mat belongs to the manufacturing technology of mahjong mats, and particularly relates to a novel method for manufacturing a mahjong mat by a plurality of small bamboo blocks.
Background
At present, the existing mahjong mat has many types, but a plurality of small bamboo blocks are penetrated into the mahjong mat by adopting a threading method, and the mahjong mat manufactured by the method has a large number of defects, such as looseness and discomfort of the small bamboo blocks, extremely high requirement on the strength of threading, easy breakage of threading, easy falling of the small bamboo blocks, low working efficiency during threading, deep hole of the small bamboo blocks, high requirement on deep hole drilling technology, high difficulty and the like.
Disclosure of Invention
The invention aims to overcome the defects of the existing mahjong mat, and provides the novel mahjong mat without the wire, which is smooth and comfortable, durable in use and high in production efficiency.
The technical scheme adopted by the invention for solving the technical problems is as follows: the injection molding mahjong mat comprises; the specific method is that a whole bed of mahjong mat is formed in a one-step injection molding mode through an injection molding method, the distance between small bamboo blocks is 3 mm, two air vents are formed in the front face of each small bamboo block, the V-shaped grooves are formed in the periphery of the side face of each small bamboo block, plastic is injected into the bottom and the peripheral V-shaped grooves of the small bamboo blocks to form five-face plastic coating of the small bamboo blocks, the plastic bag bottom is arranged below each small bamboo block, two air vents are formed in the plastic bag bottom and communicated with the air vents of the small bamboo blocks, the reinforced plastic outer edge is arranged on the periphery of the mahjong mat, the width of the edge is 15 mm, and the thickness of the reinforced plastic outer edge is larger than that of each small bamboo block.
In the injection molding mahjong mat, the high-temperature plastic solution is only injected to the periphery of the small bamboo blocks to form the four-side plastic coating of the small bamboo blocks.
The invention has the advantages that the small bamboo blocks do not need to be drilled with deep holes, the process is simpler, the mahjong mat is more compact and flat after being formed, the use is more comfortable, the small bamboo blocks can not be separated, the injection molding is carried out at one time, the production efficiency is high, and the production cost is low.

Detailed description of the invention
[ example 1 ]
Fig. 1 is a schematic structural diagram of a finished product after injection molding.
The whole bed of the mahjong mat is formed by one-time injection molding by using an injection molding method, the distance between the small bamboo blocks 1 is 3 mm, two through holes, namely vent holes 2, are formed in the front face of each small bamboo block 1, the periphery of the mahjong mat is provided with reinforced plastic outer edges 4, the width of each edge is 15 mm, the thickness of each small bamboo block is larger than that of each small bamboo block 1, the strength is increased mainly, the outer edges 4 are prevented from being broken, and the outmost small bamboo blocks 1 are prevented from falling off.
FIG. 2; sectional view of five-surface plastic-coated structure.
The bamboo block is a partial sectional view of a figure 1, V-shaped grooves 3 are formed in the periphery of the side face of each small bamboo block 1, the outer edge 4 of reinforced plastic, a plastic bag bottom 5 and diamond-shaped plastic partition strips 7 are integrated into a whole and are formed in a one-step injection molding mode, plastic is injected into the bottom of each small bamboo block 1 and the V-shaped grooves 3 in the periphery, dotted lines in the figure 2 are groove bottoms of the V-shaped grooves 3, the diamond-shaped plastic partition strips 7 are formed between every two adjacent small bamboo blocks 1, and two vent holes 6 are formed in the plastic bag bottom 5 and communicated with the vent holes 2 of the small bamboo blocks 1. The V-shaped groove 3 has the function that plastics around the small bamboo blocks 1 form a dovetail groove structure, and the deep grooves on the four sides enable the small bamboo blocks 1 not to be separated from the mahjong mat.
[ example 2 ]
FIG. 3; a cross section of the four-side plastic-coated structure.
The plastic bag bottom 5 is eliminated on the basis of the structure shown in figure 2, only the reinforced plastic outer edge 4 and the diamond-shaped plastic partition strip 7 are reserved, and plastic is injected only around each small bamboo block 1.
The two specific embodiments have simple structure, mature required technology and easy implementation, the mahjong mat is formed by one-time injection molding, is flat and comfortable, the small bamboo blocks cannot fall off, and the mahjong mat is durable and high in production efficiency, and the two specific embodiments effectively achieve the purpose of the invention.
