Description

Technical Field

[0001] The utility model relates to the technical field of square basin injection mould manufacturing, in particular to a slanted top interchangeable square basin mould. Background Art

[0002] Disposable thin-walled plastic square basins are often used for flushing and storing instruments during surgery. When changing dressings clinically, disinfectants and dressing instruments, such as cotton balls and tweezers, are often carried, which can reduce the carrying of instruments during dressing changes and facilitate work; it can also be equivalent to a trash can in the treatment tray, flushing or holding used cotton swabs, gauze blocks, and various discarded needles. It has a wide range of applications in the medical field, so medical institutions have a large demand for such products; At present, the production of such products mostly adopts injection molding technology, which is a multifunctional manufacturing process that can be used to manufacture products with a variety of materials. First, a mold is made according to the shape of the desired product, and then a screw machine is used to inject the molten plastic into the mold, and then the mold is cooled until the plastic solidifies. Once solidified, the product can be taken out of the mold and ready for use.

[0003] However, in actual applications, square basins are usually upgraded based on the original products according to market development trends and customer needs, such as adding buckles to wind guide wires in plastic square basins, changing product LOGOs according to customer requirements, etc. Guide wires are often used in interventional surgeries. Guide wires are generally smooth, slender and elastic. They are easy to spread out when placed in a square basin, and multiple wires are easy to get tangled together when taken out, making them difficult to take out. In order to prevent the guide wires from rebounding and getting tangled together, which increases the operation time, buckles are added to the four inner walls of the square basin to increase the product usage scenarios, making the product multi-functional and further improving its market competitiveness.

[0004] However, when using injection molding technology to produce products, it is often necessary to design a set of corresponding molds based on the shape and structure of each product. As the product structure changes, the mold often needs to be redeveloped, which further increases the cost of upgrading the product. In addition, the thin-walled square basin is thin and the overall structural rigidity of the product is low. Changing it to a wire-guided square basin with a buckle will make it difficult to demold the buckle during production. For this reason, a slanted-top interchangeable square basin mold is proposed.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-7In an embodiment of the utility model, a square basin mold with interchangeable inclined tops includes a movable mold group and a fixed mold group adapted to the movable mold group. The movable mold group includes a movable mold plate 5, a movable mold core 2 fixed on the movable mold plate 5, and multiple inclined tops arranged on the movable mold core 2. The ends of the multiple inclined tops passing through the movable mold plate 5 are all equipped with fixed blocks 6, and the multiple fixed blocks 6 are all plugged with positioning pins 11 for fixing the inclined top ends. The multiple fixed blocks 6 are all installed on the surface of the ejection mechanism. A movable mold bottom plate 10 is provided below the movable mold plate 5. The movable mold plate 5 is connected to the movable mold bottom plate 10 through support legs 9, and studs 13 that pass through the support legs 9 and are threadedly connected to the movable mold plate 5 are installed on the movable mold bottom plate 10.

[0027] Specifically, the movable mold core 2 is equipped with multiple inclined tops. When the inclined top needs to be replaced, the staff first rotates the stud 13 to pull it out, and then removes the movable mold base plate 10 and the supporting legs 9 in turn. The staff then knocks out the positioning pin 11 plugged into the fixed block 6. When the positioning pin 11 is disengaged, the fixed block 6 can be separated from the inclined top. Finally, the inclined top is pushed out from bottom to top to complete the replacement. The type of replacement of the inclined top can be determined according to the model of the square basin to be injection molded, whether to replace the inclined top 1 without claws or the inclined top 3 with claws, thereby avoiding the need for additional customized molds that are compatible with it, thereby reducing the production cost.

[0028] See also Figure 1 In one embodiment, in this embodiment, preferably, a plurality of movable cavities 12 for the inclined top to pass through are opened on the movable template 5, and guide blocks 4 are installed inside the plurality of movable cavities 12. Furthermore, the setting of the movable cavity 12 can not only provide an installation position for the guide block 4, but also provide a guiding and air-avoiding function for the inclined top, which can avoid wear caused by too tight fit between mold components, and at the same time improve the processing efficiency and service life of the mold.

[0029] See also Figure 1 In one embodiment, in this embodiment, preferably, the guide block 4 is connected to the movable template 5 by screws, a through hole is opened on the guide block 4, and the inner diameter of the through hole is adapted to the inclined top. Further, when the guide block 4 is excessively worn and needs to be replaced, the guide block 4 can be replaced by simply pulling out the screws fixing the guide block 4.

[0030] See also Figure 1 In one embodiment, in this embodiment, preferably, the ejection mechanism includes a lower ejection plate 7 and an upper ejection plate 8, the upper ejection plate 8 is located above the lower ejection plate 7, and the upper ejection plate 8 and the lower ejection plate 7 are connected by screws.

[0031] See also Figure 2 In one embodiment, in this embodiment, preferably, the end surface of the movable mold core 2 adjacent to the fixed mold group is set as a mold core demolding surface 14, and the end surface of the movable mold core 2 adjacent to the fixed mold group is provided with multiple vacuum air caps 15.

[0032] Specifically, the entire demoulding surface 14 of the mold core is treated by sandblasting to form a frosted surface, which reduces adhesion during demoulding of the product in the later stage, facilitates exhaust, and makes demoulding smoother; there are two vacuum air jacks 15, which are located at opposite corners of the movable mold core 2. This design is for better demoulding and reduced deformation. When the mold is opened, the product is first ejected by the vacuum air jack 15 and then pushed out by the inclined top to complete the demoulding action.

[0033] See also Figure 4-7 In one embodiment, in this embodiment, preferably, the fixed mold assembly includes a fixed mold core 17 adapted to the movable mold core 2, and the inner wall of the fixed mold core 17 is provided with multiple ejection air tops 16. The function of the ejection air top 16 is consistent with the function of the vacuum air top 15 in the movable mold core 2, and the ejection action is performed for the smooth demolding of the product. The fixed mold core 17 is detachably equipped with a logo insert 18, and the logo insert with words and the logo insert without words can be replaced according to actual conditions. The inner wall of the fixed mold core 17 is provided with vertical and horizontal guide grooves 19. Since this medical square basin is a thin-walled product, if it is designed according to the conventional method, it will lead to insufficient rigidity of the overall structure. Therefore, this vertical and horizontal guide groove 19 is added to the bottom of the basin, thereby improving the insufficient rigidity caused by the thin wall, thereby increasing the rigidity of the basin bottom structure while reducing the product cost. The end face of the fixed mold core 17 is installed with a gate runner 23, and the plastic melt enters the entire mold cavity from the gate runner 23 to complete the injection molding of the entire product.

[0034] See also Figure 6 In one embodiment, in this embodiment, preferably, a pressure block 21 for fixing the logo insert 18 is installed on the end surface of the fixed mold core 17, and the pressure block 21 is connected to the logo insert 18 through a fastening stud 22. Further, the fastening stud 22 is used to complete the fixing function of the entire insert. When it needs to be disassembled and replaced, the fastening stud 22 is loosened and the logo insert 18 is taken out using a gun extraction tool to replace the insert to be used and then it can be firmly installed again.

[0035] See also Figure 4-5 In one embodiment, in order to increase the rigidity of the thin-walled square basin, in this embodiment, preferably, a circle of reinforcing ribs 20 is provided along the edge of the opening of the fixed mold core 17. Furthermore, the structural reinforcement design of the upper structure ensures that the medical square basin will not be significantly deformed when filled with liquid, thereby satisfying the actual use effect.

[0036] The working principle and use process of the utility model are as follows: hot melt is injected into the closed mold through the gate flow channel 23, and after cooling and shaping, the molten plastic is solidified to become the required plastic part, and then ejected by the vacuum air ejector 15 and the ejector air ejector 16, and the inclined ejector is pushed out by the ejection mechanism to complete the demoulding work of the product, and retracted by the ejection mechanism before the next injection molding work, and the injection molding production work is completed in this reciprocating manner.
