Abstract
The utility model discloses a device for injection molding and sealing of a central venous catheter. The device is capable of protecting tubes as well as guaranteeing sealing effects. The device comprises a die frame, a die, a pouring opening and a die cavity, wherein a duct in which a perfusion tube or a liquid charging tube is inserted is arranged on the side wall of the die, the diameter of the duct is larger than those of the perfusion tube and the liquid charging tube, sealing silicon rubber is arranged inside the duct, a channel which connects the die cavity with the outside is arranged in the sealing silicon rubber, the diameter of the channel is the same as those of the perfusion tube and the liquid charging tube, a sliding block which abuts against the sealing silicon rubber is arranged next to the die, and the sliding block is assembled on the die frame in a sliding mode.
Description
Technical field:
The utility model relates to a kind of equipment of CVC injection moulding sealing.
Background technology:
When carrying out infusion treatment, need inject two kinds of injections simultaneously to patient sometimes and cure, at this moment need be equipped with the infusion pipeline that has CVC c and carry out infusion treatment; The input of CVC c is provided with two liquid pushing tube b, and liquid pushing tube b plugs into respectively and stores the container of different injections, and the output of CVC c is a woven hose a; The other end of this woven hose a imports human body through seal wire, and the effect of CVC c is to compile two kinds of different injections, is input into soup in the human body body together again; As shown in Figure 1; When making infusion pipeline, need be placed on the link of woven hose a and liquid pushing tube b in advance in the CVC die cavity, then toward die cavity injecting glue moulding CVC c; CVC c after the moulding just can directly realize that with woven hose a and liquid pushing tube b sealing has been connected like this; Existing device structure is on the sidewall of die cavity, the duct to be set, and before the injecting glue moulding, passing hole channel is placed on the link of woven hose a and liquid pushing tube b in the die cavity in advance; Matched moulds injecting glue moulding then; But because can there be tolerance in woven hose a and liquid pushing tube b when extrusion molding, occur two kinds of situation when causing mold injects moulding sealing: 1. when the diameter of woven hose a and liquid pushing tube b was all bigger than normal, mould can weigh woven hose a and liquid pushing tube b wounded; 2. when woven hose a and liquid pushing tube b were less than normal, the injecting molding die envelope is glue incessantly.
Summary of the invention:
The purpose of the utility model is in order to overcome the shortcoming of above-mentioned prior art, to provide a kind of and both can protect tubing, can guaranteeing the equipment of the CVC injection moulding sealing of sealing effect again.
The goal of the invention of the utility model can realize through following technical scheme: a kind of equipment of CVC injection moulding sealing; Include mould bases, mould, sprue gate and die cavity; On the sidewall of mould, be provided with the duct that supplies woven hose or liquid pushing tube to inject; The diameter in this duct is bigger than woven hose and liquid pushing tube diameter, in the duct, is provided with silicone rubber for sealing, and silicone rubber for sealing is provided with and connects die cavity and the passage extraneous, that diameter is the same with the liquid pushing tube diameter with woven hose.
Be provided with the slide block that withstands silicone rubber for sealing on the next door of mould, the slide block cunning is assigned on the mould bases.
After adopting the present technique scheme, the beneficial effect of the utility model is: through between mould and woven hose or liquid pushing tube, silicone rubber for sealing being set, if when woven hose and liquid pushing tube diameter are bigger than normal, can play the effect of protecting woven hose and liquid pushing tube not to be weighed wounded; When if woven hose and liquid pushing tube diameter diminish, utilize the elasticity of silicone rubber for sealing, guarantee sealing, guarantee the reliability of sealing, greatly improved yield rate.
Description of drawings:
Fig. 1 is the structural representation of infusion pipeline;
Fig. 2 is the structure chart of the utility model CVC injection moulding sealing equipment;
Fig. 3 is the enlarged drawing of A part among Fig. 2;
Fig. 4 is the decomposition chart of Fig. 3.
The specific embodiment:
Below in conjunction with accompanying drawing this utility patent is described further.
The equipment of the CVC injection moulding sealing of present embodiment includes mould bases 1, mould 2, sprue gate 3 and die cavity 4; Mould 2 is divided into patrix 21 and counterdie 22; On the sidewall of mould 2, patrix 21 and counterdie 22 matched moulds places are provided with the duct 5 that supplies woven hose a or liquid pushing tube b to inject; The diameter in this duct 5 is bigger than woven hose a and liquid pushing tube b diameter; In duct 5, be provided with silicone rubber for sealing 6, silicone rubber for sealing 6 is provided with and connects die cavity 4 and the passage 61 extraneous, that diameter is the same with liquid pushing tube b diameter with woven hose a.Be provided with the slide block 7 that withstands silicone rubber for sealing 6 on the next door of mould 2, slide block 7 sliding being assigned on the mould bases 1.
During production operation, be set on silicone rubber for sealing 6 on the link of woven hose a and liquid pushing tube b earlier, be placed on silicone rubber for sealing 6 in the duct groove of counterdie 22 then; The end of woven hose a and liquid pushing tube b puts in counterdie 22 die cavitys simultaneously; Then close patrix 21 and counterdie 22, silicone rubber for sealing 6 is pushed down in pusher movable slider 7 slips of closing, next just can the injecting glue moulding; Finished product is taken out in die sinking after the moulding, pulls out silicone rubber for sealing 6 along woven hose body and liquid pushing tube body.
The above only is the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction.Any those of ordinary skill in the art; Do not breaking away under the utility model technical scheme scope situation; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to the utility model technical scheme, or are revised as the equivalent embodiment of equivalent variations.So every content that does not break away from the utility model technical scheme, the equivalence of doing according to shape, structure and the principle of the utility model changes, and all should be covered by in the protection domain of the utility model.
