Problems solved by technology

[0002] At present, the domestic production of cruciform drainage tubes is cumbersome and inefficient, and the quality of the products cannot be guaranteed. It is to extrude silicone rubber tubes and cruciform strips separately, and then cut the required lengths, and pass them through the mold at high temperature with the help of adhesives. , high pressure shaping to form a silicone rubber cross flower drainage tube
The product produced by this method has low efficiency, and the adhesive is not the body glue at the bonding place, so the bonding strength here is lower than that of the body glue, which causes the round tube and the cross bar to be easily broken, which will cause damage to the patient during use. risk to its safety

specific Embodiment 1

[0029] see figure 1 It can be seen that a silicone rubber double-shaped tube integrated molding device of the present invention includes an integrated molding device body 2; the outer body 2 of the integrated molding device is provided with a casing, and a composite mold A8 and a composite mold B11 are arranged in the casing. The side is provided with a main material channel 4 and an auxiliary material channel 5. The composite mold A8 is formed by a combination of a cross 6 and a core mold 7, and the composite mold B11 is formed by a combination of a circular die 9 and four injection needles 10. One end of the integral molding device body 2 is provided with a connecting rod 3, and the other end of the integral molding device body 2 is provided with a fixed seat 1 of the composite mold B, the composite mold A8 is arranged on the fixed seat of the composite mold A8, and the connecting rod 3 is connected to the composite mold A8 and Composite mold B11 has two auxiliary material c...

specific Embodiment 2

[0030] A method for processing a silicone rubber double-shaped tube integrated molding device, characterized in the integrated molding method:

[0031] 1) Forming of cross strips: Silicon rubber is extruded through the main material channel 4 and auxiliary material channel 5, and the connecting rod 3 drives the cross 6 to move upwards and separate from the composite mold A8 to form the cross strips. The die 9 of the silicone rubber round tube is Circular, 4 quarter arc blocks on the block are compounded into a cross flower shape, and the four needles 10 move radially to the axis and cooperate with the core mold 7 to form the opening of the cross flower strip. The two actions are carried out at the same time. At this moment, the rubber material flows through the space of the forming device to form a cross flower strip;

[0032]2) Forming of circular tube: The circular tube is jointly molded by the composite mold A8 and the composite mold B11, and the silicone rubber flows throu...

Abstract

The invention discloses an integrated forming device for a silicone rubber double-form tube. The integrated forming device comprises an integrated forming device body. A shell is arranged outside theintegrated forming device body. A composite mold A and a composite mold B are arranged in the shell. A main material channel and auxiliary channels are arranged on the side face of the shell. The composite mold A is formed by combining a crossed frame and a core pattern mold in a sleeving manner. The composite mold B is formed by combining a circular mouth-like mold and four injection needles in asleeving manner. A connecting rod is arranged at one end of the integrated forming device body. A fixing seat of the composite mold B is arranged at the other end of the integrated forming device body. A silicone rubber circular tube is formed by combining the cylindrical mouth mold composite B and the cylindrical core mold composite A. The silicon rubber circular tube can be produced in a gap where a rubber material flows. A silicon rubber crossed-shaped pattern strip is completed on the dependence of the crossed mouth mold, and on this basis, in order to achieve integrated production, continuous switching of the circular tube and the related molds of the crossed strip is completed, coherent actions can be achieved, and the desired production product is obtained.

Description

technical field [0001] The invention relates to the technical field of silicone rubber production methods and production tools, and more precisely relates to a silicone rubber double-shaped tube integral molding device. Background technique [0002] At present, the domestic production of cruciform drainage tubes is cumbersome and inefficient, and the quality of the products cannot be guaranteed. It is to extrude silicone rubber tubes and cruciform strips separately, and then cut the required lengths, and pass them through the mold at high temperature with the help of adhesives. , High-pressure shaping to form a silicone rubber cross flower drainage tube. The product produced by this method has low efficiency, and the adhesive is not the body glue at the bonding place, so the bonding strength here is lower than that of the body glue, which causes the round tube and the cross bar to be easily broken, which will cause damage to the patient during use. pose a risk to its safety...
