Detailed Description
The following is a further description of embodiments of the utility model, taken in conjunction with the accompanying drawings:
as shown in fig. 1 to 5, a mold for producing a medical product includes a base 1, a lower mold 2, and an upper mold 3;
The lower die 2 is fixedly arranged on the base 1, an upper die 3 is arranged at one end, far away from the base 1, of the lower die 2, and a lower die core 4 and an upper die core 5 are respectively arranged in the lower die 2 and the upper die 3;
The inside of the lower mold core 4 is provided with a sliding block 6, the top surface and the bottom surface of the sliding block 6 are both in an outer arc surface 7 structure, and the distance between the outer arc surface 7 of the sliding block 6 and a plane formed by two ends of the sliding block 6 is 0.1-0.2mm; in this embodiment, the distance between the outer arc surface 7 of the sliding block 6 and the plane formed by the two ends of the sliding block 6 is quite small, which is hardly observed by naked eyes (but can achieve the anti-deformation effect), because when the distance or the amplitude of the outer arc surface 7 is large, the concave amplitude of the inner side surface of the injection molded medical product 11 is large, and even if the inner side surface is continuously contracted in the whole cooling process, the inner side surface cannot be finally formed into a flat plane; therefore, the amplitude or distance of the extrados 7 in this embodiment is set to achieve a better anti-deformation effect for the medical product 11.
As a preferred embodiment; the distance between the extrados 7 of the sliding block 6 and the plane formed by the two ends of the sliding block 6 is 0.15mm; the distance is set so that the medical product 11 achieves the optimal anti-deformation effect; the leveling effect of the inner side surface is optimal.
As a preferred embodiment; a driving cylinder 8 is fixedly arranged on the side surface of the lower die 2, and a push rod end of the driving cylinder 8 is fixedly connected with the lower die 2 and the lower die core 4 and the sliding block 6; it can be understood that when the injection molding of the medical product 11 is completed, the driving cylinder 8 is required to drive the sliding block 6 to separate from the medical product 11, so that the medical product 11 can be conveniently ejected by the following ejector pin 9; it should be noted that the lower die 2 is further provided with a groove body moving through the sliding block 6, so that the sliding block 6 can move conveniently.
As a preferred embodiment; the base 1 is provided with a plurality of ejector pins 9 and a driving mechanism for driving the ejector pins 9 to move up and down, the driving mechanism can adopt small-sized air cylinders and is fixedly arranged on the base 1, each ejector pin 9 is connected with one small-sized air cylinder, and the small-sized air cylinders are controlled to act uniformly through a controller; the movable end of the thimble 9 is communicated with the lower mold core 4; through the setting of a plurality of thimble 9, can effectively be with the medical product 11 after the completion of moulding plastics ejecting, simultaneously, medical product 11 can even atress, effectively avoids appearing the condition of damage.
As a preferred embodiment; a feeding pipe 10 is further arranged on the upper die 3, and the feeding pipe 10 is communicated with the upper die 3; injection molding materials can be injected into the lower mold core 4 and the upper mold core 5 by arranging a feed pipe 10;
it should be noted that the lower die 2 and the upper die 3 are not fixedly connected, but are inserted together through positioning rods and positioning holes arranged on the lower die 2 and the upper die 3, and after injection molding is completed, the upper die 3 can be opened through an external driving mechanism and then demoulding operation is performed.
The principle of the reverse deformation of the medical product 11 of the utility model is as follows: in the process of injection molding of the medical product 11, the top surface and the bottom surface of the sliding block 6 are of the structure of the outer arc surface 7, and when the medical product 11 is injected, the outer arc surface 7 props against the upper side and the lower side of the hollow inside of the medical product 11, so that after the injection molding of the medical product 11 is completed, the upper side and the lower side of the hollow inside of the medical product 11 are of the concave structure, and therefore, the medical product 11 can continue to shrink in the cooling process, and the original inner concave surface is deformed into a flat plane, so that the effect of reverse deformation is achieved.
It should be noted that the main problems in the prior art are: after the medical product 11 is injection molded and demolded, a jig is needed to be inserted into the middle structure 12, so that the medical product 11 is prevented from shrinking inwards to influence the quality of the medical product; however, the process requires a certain labor force, thereby increasing the labor cost; moreover, the production process is increased, resulting in a decrease in the production efficiency of the medical product 11;
Therefore, after the improvement of the application, the structure of the extrados 7 is arranged on the sliding block 6, so that the medical product 11 achieves the effect of inverse deformation in the cooling process, the product quality is more stable, the production efficiency is higher, and meanwhile, the manpower expenditure is reduced, and the production cost is reduced.
The above embodiments are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, and various modifications and improvements made by those skilled in the art to the technical solution of the present utility model should fall within the scope of protection defined by the claims of the present utility model without departing from the spirit of the design of the present utility model.
