DETAILED DESCRIPTION

[0035] The technical solutions of the present invention are further described in detail below through examples and in conjunction with the accompanying drawings, but the present invention is not limited to the following examples.

[0036] In view of the defects of the prior art in manufacturing rubber gloves through dipping process and general molding process, the present invention provides a die-casting mold and die-casting equipment for manufacturing vulcanized rubber gloves.

[0037] The technical solutions of the present invention can solve the following technical problems: Due to the poor fluidity of natural rubber and synthetic rubber (compared with thermoelastic materials such as PVC, TPR, and TPU), flowing in the mold cavity of thin products (0.2-1 mm) can easily cause problems such as dead rubber, mold expansion, and mold core deviation; conventional processes are difficult to produce lined rubber gloves, etc.

[0038] The rubber gloves manufactured by the mold or the device of the present invention have no limit on length and can be as long as the wrist or the shoulder, and the thinnest thickness can be 0.2 mm.

[0039] Figures 1 to 7 illustrate a preferred method for manufacturing a pair of gloves. However, the present invention also includes an embodiment for manufacturing a single glove. In this case, only features corresponding to one glove need to be retained, such as the inner cavity corresponding to one glove and the middle plate hand mold and hand mold corresponding to one glove.

[0040] FIG1 shows a non-assembled state diagram of a die-casting mold for manufacturing vulcanized rubber gloves according to one embodiment of the present invention.

[0041] The die-casting mold includes assembled side plate molds 41 and 42, which, when assembled, have an inner cavity substantially corresponding to the shape of a human hand. Figure 1 illustrates a glove that does not distinguish between left and right hands. In this case, the side plate molds 41 and 42 are preferably two matching and substantially symmetrical split molds that can be matched to each other using matching features and can be fastened together, for example, by hydraulic pressure.

[0042] In other embodiments, the glove can be a glove for distinguishing between left and right hands. In this case, the side panel molds 41 and 42 match each other but are not symmetrical. Specifically, the parts of the inner cavity distributed on the two side panel molds 41 and 42 are asymmetrical to each other.

[0043] In the die-casting mold of FIG1 , the side plate molds 41 and 42 include two inner cavities corresponding to a pair of gloves. It can be seen that half of each of the two inner cavities is provided in the side plate mold 41 and the side plate mold 42. When the side plate molds 41 and 42 are closed, two complete inner cavities are formed.

[0044] The die-casting mold of FIG1 may further include a center hand mold 31 with a partitioning element 33, having a main body 34 substantially corresponding to the shape of a human hand, and a partitioning element 33 disposed on the main body. The center hand mold 31 is adapted to be installed within the side molds 41 and 42 to form a die-casting cavity between the walls of the inner cavities of the side molds 41 and 42 and the outer surface of the main body 34 of the center hand mold 31. When the center hand mold and side molds are installed, each die-casting cavity is divided into two parts by the center hand mold and the side molds.

[0045] The dividing element of the middle plate mold is preferably a separator plate. The separator plate can be located midway through the thickness of the middle plate mold body, extending from the outside of the middle plate mold body. When the middle plate mold is installed in the corresponding inner cavity of the side plate mold, the separator plate separates the corresponding die-casting cavity into a left chamber and a right chamber, corresponding to the side plate molds 41 and 42, respectively. The separator plate can be, for example, 40 mm thick or slightly thinner.

[0046] The die-casting mold of FIG1 includes a pair of center plate hand molds 31 corresponding to a pair of gloves. The pair of center plate hand molds 31 are suitable for being respectively installed in the two inner cavities formed when the side plate molds 41 and 42 are closed, forming a die-casting molding cavity for a pair of gloves.

[0047] As shown in Figure 7, the middle plate hand mold 31 also includes: a longitudinally extending glue injection channel (main glue inlet channel) extending longitudinally downward from the upper part of the middle plate hand mold, and a transversely extending glue injection channel extending transversely from the longitudinally extending glue injection channel to the glue outlet 71 on the surface of the middle plate hand mold.

[0048] According to the die-casting mold of the present invention, the die-casting mold further includes a guide plate 21 suitable for being installed on the top of the side plate mold to guide the injection of rubber, and the guide plate is provided with: a guide hole 22 suitable for injecting rubber; and a guide channel, which connects the guide hole to the longitudinally extending rubber injection channel.

[0049] According to a preferred embodiment of the present invention, the die-casting mold may further include a glue injection plate 11, adapted to be attached to the upper portion of the guide plate and including a glue injection hole 12 adapted to be connected to an external injection head for externally injecting glue into the guide plate. The glue injection plate may be provided with a cold runner system for cooling the glue to prevent the formation of dead glue.

[0050] Figure 7 is a schematic cross-sectional view of the die-casting mold in an assembled state, illustrating the interconnected relationship between the injection holes and the injection channels. In other embodiments, the injection plate and the guide plate can be formed into a single plate, provided with the injection holes, the guide channels and the cold runner system.

[0051] According to the present invention, the top of the side panel mold and the bottom of the guide plate, as well as the top of the guide plate and the bottom of the glue injection plate, have matching joints. The glue injection plate is adapted to be molded onto the top of the guide plate via these joints, and the guide plate is adapted to be molded onto the top of the side panel mold via these joints. Figure 7 schematically illustrates these matching concave and convex portions. Other joint elements may also be used.

[0052] In the present invention, the middle plate hand mold corresponding to a single glove may include a single longitudinally extending glue injection channel or two or more longitudinally extending glue injection channels spaced apart. In the embodiment shown in FIG7 , the middle plate hand mold includes two middle plate hand molds corresponding to a pair of gloves, each middle plate hand mold including a longitudinally extending glue injection channel or a main glue feed channel.

[0053] According to a preferred embodiment of the present invention, the die-casting mold may further include a plurality of transversely extending glue injection channels extending from each longitudinally extending glue injection channel. In the embodiment of FIG7 , transversely extending glue injection channels are provided at positions corresponding to the base of the palm and the middle of the fingers, respectively. Transversely extending glue injection channels are also provided at positions corresponding to the arms, which are shown in FIG7 as extending forward and backward. In other embodiments, the extension directions of the transversely extending glue injection channels may be different, and may even be staggered with each other. A glue outlet 71 is provided on the transversely extending glue injection channel, and the glue enters the die-casting cavity through the glue outlet 71.

[0054] According to a preferred embodiment of the present invention, the longitudinally extending glue injection channel extends in the vertical direction, the transversely extending glue injection channel extends in the horizontal direction, and the multiple glue outlets to which the multiple transversely extending glue injection channels extend are staggeredly distributed on the surface of the middle plate hand mold.

[0055] The diameter of the longitudinally extending glue injection channel is 10-20 mm, and the diameter of the transversely extending channel is 2-5 mm.

[0056] When the mold is assembled, the thickness of the die-casting cavity formed is 0.2mm-1mm.

[0057] According to a preferred embodiment of the present invention, the die-casting mold may further include a second hand mold 51 without a separating element. The second hand mold 51 has a substantially identical shape to the main body 34 of the middle plate hand mold and is adapted to fit within the inner cavity of the side plate mold. The second hand mold 51 can be used to add a glove lining to the manufactured glove, as will be described in detail below.

[0058] The inner surface of the side plate mold has features suitable for bonding with the rubber surface, for example, its material can be suitable for bonding with rubber, or form a certain texture.

[0059] According to the present invention, there is also provided a die-casting apparatus for vulcanized rubber gloves, comprising a die-casting mold according to the present invention; a high-pressure injection mechanism for pressurizing and injecting a prepared unvulcanized rubber compound into a glue injection hole of the die-casting mold; a mold moving mechanism for moving various parts of the die-casting mold according to a pre-set program, such as various hydraulic operating mechanisms; and a control mechanism for controlling the operation of the mold moving mechanism and the high-pressure injection mechanism.

[0060] The die-casting molding equipment may further include a heating device for heating the unvulcanized mixed rubber material.

[0061] The operation of the die-casting mold and die-casting equipment according to the present invention can refer to the following manufacturing method.

[0062] According to another aspect of the present invention, there is provided a method for manufacturing vulcanized rubber gloves using the above-mentioned die-casting molding apparatus, for example comprising the following steps:

[0063] 1. Separate the parts of the side panel mold and move the middle panel hand mold with the separation element between the parts of the side panel mold.

[0064] 2. Close the side plate mold to accommodate the middle plate hand mold with the partition element in the appropriate position in the side plate mold; at this time, the mold can be fixed in place by appropriate positioning and clamping devices, such as hydraulic or mechanical positioning and clamping devices.

[0065] For example, a center plate hand mold with a partitioning element is positioned within the side plate mold by engaging its partitioning element or positioning step with the positioning element of the side plate mold. Additional fixing devices can be provided in the die casting apparatus to secure the side plate mold and center plate hand mold in place. For example, a hydraulic positioning device can be provided.

[0066] FIG1 shows a partitioning element and a positioning step at the lower portion of a middle plate hand mold with a partitioning element according to an embodiment of the present invention, as well as a corresponding positioning step at the lower portion of a side plate mold.

[0067] 3. Position and fix the guide plate on the top of the side plate mold, and position and fix the injection plate on the top of the guide plate.

[0068] As mentioned above, the lower portion of the deflector plate and the top of the side plate mold can be provided with engaging positioning elements. Additional fixing devices can be incorporated into the die-casting equipment to secure the deflector plate, glue injection plate, and side plate molds in place. For example, a hydraulic positioning device can be provided. In this case, the outlet of the glue injection channel of the glue injection plate is connected to the deflector plate, and in turn to the inlet of the longitudinal glue injection channel at the top of the middle plate hand mold.

[0069] FIG7 shows the positioning of the glue injection plate, guide plate and side plate molds in this state, and the connection state between the glue injection hole and the glue injection channel.

[0070] 4. Inject glue into the injection hole of the injection plate (inject unvulcanized mixed rubber), and then inject the unvulcanized mixed rubber into the longitudinal injection channel of the middle plate hand mold through the injection channel of the injection plate and the guide plate, and then inject the unvulcanized mixed rubber into the transverse injection channel, so that the unvulcanized mixed rubber enters the die-casting molding cavity between the side plate mold and the middle plate hand mold with the partition element.

[0071] The injection mechanism maintains high pressure to inject the unvulcanized rubber mix. Injection outlets staggered across the center plate mold surface direct the unvulcanized rubber mix into the separate die-casting cavities, reducing injection pressure and evenly distributing the unvulcanized rubber mix within the die-casting cavities. The unvulcanized rubber mix in the injection mechanism can be heated appropriately to improve its fluidity.

[0072] A cold runner system can be provided in the injection plate to prevent the formation of dead glue.

[0073] 5. Open the side plate mold and remove the middle plate hand mold with the partition element.

[0074] At this point, as the unvulcanized rubber mix is ​​molded under pressure and temperature in the separate die-casting cavities, two separate sections 61 of each glove are formed. When the middle hand mold with the separator element is removed, these sections 61 remain attached to the corresponding sections of the side mold. This can be achieved, for example, by selecting the materials for the side mold and the middle hand mold with the separator element, such as by providing a rougher inner surface of the side mold; by creating a temperature difference between the middle hand mold and the side mold; or by providing features on the inner surface of the side mold that facilitate bonding of the rubber glove sections (e.g., texture).

[0075] 6. Put the second hand mold without the separator element on the glove lining and move it between the side plate molds.

[0076] FIG3 shows the state at this time.

[0077] 7. Close the side panel mold to accommodate the second hand mold without the dividing element in the appropriate position in the side panel mold.

[0078] FIG4 shows the state at this time.

[0079] The positioning of the second hand mold in the side panel mold is similar to the above-mentioned middle panel hand mold with separation elements.

[0080] At this time, the side plate mold is closed and, together with the second hand mold without the separating element, pressurizes the various parts of the rubber glove and the inner lining of the glove to fit them together.

[0081] Because the side panel molds are modular in design, consisting of two sections, the side panel mold sections can be separated to accommodate the middle panel hand mold or the second hand mold, and can be closed to form separate die-casting cavities with the middle panel hand mold with a separator, or to form a complete glove molding cavity with the second hand mold without a separator. When the middle panel hand mold with a separator is removed, the two separate sections of each formed glove remain on the side panel mold sections. When the second hand mold with the glove lining is inserted and the side panel mold sections are closed, the two separate sections of the formed glove can be joined to each other and the glove lining.

[0082] An inflation channel can be provided in the second hand mold, and high-pressure gas can be supplied from an external air pressure source. After the mold is closed, pressurized gas is supplied to the surface of the second hand mold to press the inner lining of the glove on the surface of the second hand mold toward the inner surface of the rubber glove, thereby promoting mutual fit.

[0083] 8. Vulcanize the unvulcanized mixed rubber material.

[0084] For example, a heating device is installed near the mold to heat the closed mold, thereby heating the rubber glove and the second hand mold. Vulcanization is then performed by applying pressure to the rubber glove using the pressurized gas. At this point, the various components of the rubber glove, along with the glove lining, are combined to form a complete rubber glove. Figure 5 shows the second hand mold removed from the side plate mold after this step is completed, with a pair of gloves already formed on it.

[0085] FIG6 shows a pair of vulcanized rubber gloves made according to the present invention.

[0086] The embodiments of the present invention are not limited to the above embodiments. Without departing from the spirit and scope of the present invention, ordinary technicians in this field can make various changes and improvements to the present invention in form and details, and these are all considered to fall within the scope of protection of the present invention.
