Description

Sequential demoulding forming machine with multiple stages of serial moulds

Technical Field

The invention relates to a forming machine with a plurality of stages of serial molds, in particular to a sequential demolding forming machine with a plurality of stages of serial molds.

Background

Molding equipment is widely used in the mass production industry for various objects, wherein in any form of molding equipment, a mold is required to form various materials into products with specific dimensions and shapes, and the mold must be disassembled inevitably after the molding process is completed to take out the products. In order to improve the production efficiency, mass production is generally considered, that is, a plurality of products are produced at one time by a plurality of mold cavities in one-step forming process. For small electronic components, for example, 16, 64 or 128 mold cavities are often formed simultaneously in one mold. However, in the case of molding a large-sized molded product, a plurality of cavities cannot be formed in the same pair of molds, and a plurality of sets of molds must be handled in a batch operation.

If a plurality of sets of dies are operated in parallel, not only a relatively large factory area is occupied, but also particularly the pressurization or demolding needs to be driven synchronously, and the horsepower requirement is too high, so that the multi-set die is rarely adopted. If the multiple sets of dies are serially connected and the dies are simultaneously removed to improve the production efficiency, on one hand, a considerable space is occupied by each set of dies along the length direction of the forming machine due to the fact that a demolding space is reserved for each set of dies, on the other hand, the multiple sets of dies are synchronously actuated to perform one-time demolding, the driving mechanism is also complicated, the difficulty of actuating operation is increased, the error occurrence probability is improved, and the production yield is reduced.

Therefore, even though the mechanism actually adopted by the forming machine is a serial connection mode, the disassembling mode of each set of dies is often performed only by manually holding a specific auxiliary tool, which not only easily causes product quality defects but also consumes a lot of manpower and operation time.

Detailed Description

The invention is further illustrated with reference to the following figures and specific examples. These examples are to be construed as merely illustrative and not limitative of the remainder of the disclosure in any way whatsoever. After reading the description of the invention, one skilled in the art can make various changes and modifications to the invention, and such equivalent changes and modifications also fall into the scope of the invention defined by the claims.

First preferred embodiment

As shown in fig. 1, a sequential demolding molding machine with a plurality of mold sets according to a first preferred embodiment of the present invention is defined herein as a longitudinal direction of the molding machine 1 along a through axis in a left-right direction of the drawing for convenience of description, in this embodiment, a base portion of the molding machine 1 is a set of supporting devices 10 extending along the longitudinal direction for supporting the rest of the components of the molding machine, and in this embodiment, the supporting devices 10 further include a set of rails made of steel, for example, for guiding the mold sets to advance and retreat. The mold set 20, which is carried and guided by the carrying device 10, includes a plurality of molds 21, and since each mold is disposed on the carrying device 10, and in this embodiment, both side surfaces of each mold simultaneously serve as a portion of the mold cavities on the left side and the right side, respectively, in the present invention, the mold cavities of each mold are serially connected in a stage from upstream to downstream, and are referred to as a series of molds.

In this embodiment, each mold 21 is composed of a first mold block 211 corresponding to the mold cavity on the left side of the drawing and a second mold block 212 corresponding to the mold cavity on the right side, wherein an elastic member (not shown), such as a spring or an inclined portion, is disposed on the first mold block 211 or the second mold block 212, and each mold cavity is defined by two adjacent molds; of course, as those skilled in the art can easily understand, even if the first module 211 and the second module 212 of a mold 21 are not integrally formed, but are formed by two corresponding modules, the implementation of the present invention is still not hindered, in other embodiments, each mold may be formed by more than three corresponding modules, and the number of modules is not limited by the present invention.

In this embodiment, the molding machine 1 is a casting molding machine for molding a ceramic blank, the processed material 22 is ceramic slurry, two injection ports 213 corresponding to the left and right mold halves are formed at the top end of each mold 21 for injecting the ceramic slurry, respectively, but the injection ports may be formed in the mold block 211 or the mold block 212 separately, or formed by a part of the mold block and the mold block, respectively, and the forming method of the injection ports is not limited. Before the ceramic slurry is injected, each mold 21 is pushed to the left molding position along the longitudinal direction of the carrier 10 by the pressing device 30, so that the two adjacent left and right molds are closed, each cavity is sealed, and the hydraulic cylinder in this embodiment is used as the pressing device 30 to provide the pressure required by the mold set 20 in the molding process.

The ceramic slurry injected into each cavity is primarily heated during the molding process to evaporate water, thereby forming a plurality of ceramic green bodies in a batch in the molding machine 1. The mold 21 is then pulled individually to be demolded after the molding process is completed by a demolder 40. in the present embodiment, the demolder 40 includes a claw hook 41, which is driven by a positioning driving device 50, which is exemplified by a stepping motor and a timing belt, to start the demold one by one for sintering each ceramic blank into a final ceramic product, such as a washbasin.

In the present embodiment, when the pressing device 30 is released to start the demolding process, the elastic body provided in the first module 211 or the second module 212 can make the mold 21 automatically spring open to reduce the load of the demolding device 40, thereby saving energy. The claw hook 41 is first driven by a positioning driving device, which is exemplified by a motor and a timing belt, so as to position the claw hook 41 to a position corresponding to the rightmost mold 21, and the rightmost first mold 21 is pulled and displaced rightwards along the carrying device 10, so that the mold is moved away from the left forming position to perform a demolding movement, and the blank in the first mold cavity is exposed for the operator to take out; in the present embodiment, the demolding device 40 is disposed at the front end of the positioning driving device 50, and the stopping position of the claw hook 41 can be accurately controlled to correspond to the first mold 21 by fixing the number of actuating steps of the stepping motor in the positioning driving device 50 and selecting a timing belt with an appropriate pitch. Subsequently, as shown in fig. 2, fig. 2 is a schematic diagram of sequential demolding in the present embodiment, after the blank in the first mold cavity is taken out, the claw hook 41 is driven by the positioning driving device 50 again to be repositioned to the position corresponding to the second mold, and as shown in fig. 3, the claw hook 41 pulls the second mold to the right again to expose the blank in the second mold cavity for taking out.

Repeating the above operations, the mold removing device 40 sequentially corresponds to each mold 21 along the length direction, and pulls the corresponding mold 21 to perform the mold removing movement until all the blanks in the mold cavities are taken out. Because the demoulding process is automatic operation, the operation process is more efficient, and the output efficiency of the product is improved; and by means of the automation process, the error of manual operation is reduced, and the product yield is synchronously improved. In addition, because the moulds are opened one by one, the forming machine only needs to leave the length of all the moulds and one demoulding space, the occupied space of the forming machine is saved, and the volume is reduced.

Of course, many of the structures in the above embodiments are only examples for convenience of description, and the structures of the present invention are not limited thereby. For example, the demolding device may also be an electromagnet, a suction nozzle or the like, and for example, the positioning driving device may be a linear motor, a pneumatic cylinder, an oil cylinder, a screw rod or the like, which is common in the mechanical industry, in addition to a motor and a timing belt, without hindering the implementation of the present invention.

Second preferred embodiment

As shown in fig. 4, the second preferred embodiment of the present invention has the same parts as the first preferred embodiment, and will not be repeated, only the differences will be described, similar components also use the same names and labels, the demolding device 40 in this embodiment is explained as a set of electromagnets 42, each mold 21 is provided with at least one small iron sheet area as a ferromagnetic component 214 and corresponding to the electromagnet, while in this embodiment, the positioning driving device is exemplified by a set of multi-section hydraulic cylinders 51, the extension length of each section of the multi-section hydraulic cylinders 51 is exactly corresponding to the size of one mold, therefore, after the molding process is completed, in the process of sequential demolding, one section can be pushed out at a time, the demolding device 40 can be sequentially positioned and driven to move to the mold 21 on the left along the length direction without additionally providing a sensing component to monitor the pause position of the demolding device, thereby improving the yield of the formed product and the efficiency of the productivity of the forming machine 1.

Since the molding machine 2 of this embodiment is a plastic injection molding machine, the processed material 22 is a molten viscous plastic material, and air bubbles are left to cause product damage due to the flow of the plastic material into the mold cavities because of viscosity, an exhaust port 24 connected to each mold cavity is additionally formed below each mold for connecting to an externally disposed exhaust device 23, where the exhaust device 23 is a vacuum pump.

Third preferred embodiment

Referring to fig. 5 to 6, in a third preferred embodiment of the present invention, taking the extrusion molding machine 3 as an example, the processed raw material 22 is a sheet-shaped plastic material or a powder material pre-filled in the mold cavity. The positioning driving device 50 of the present embodiment includes a screw advancing and retracting component 52 and a sensing positioning component 53, the screw advancing and retracting component 52 is exemplified by a stepping motor driver 521 and a lead screw 522, although a similar structure such as a stepping motor driver and a ball screw may be used instead, and the sensing positioning component 53 may be selected from an optical ruler 531, a magnetic ruler or other similar components. Since the mold releasing device 40 in this embodiment includes the suction nozzles 43, each mold 21 must be provided with a corresponding flat portion 215 for receiving the suction force corresponding to the suction nozzles 43.

In the forming machine 3 of the present embodiment, after the forming process is completed, the sensing and positioning assembly 53 controls the screw advancing and retreating assembly 52 to sequentially position and drive the demolding device 40 to correspond to each mold 21 along the longitudinal direction, and the corresponding molds 21 are pulled one by one to perform the demolding movement to take out the formed product, so as to achieve the effects of improving the yield of the formed product and the productivity efficiency of the forming machine 1.

In summary, the sequential demolding machine with multiple stages of serial molds provided by the invention drives the demolding device to correspond to each mold along the length direction through the positioning driving device in a sequential positioning manner, and pulls the corresponding molds to perform demolding movement one by one, thereby not only synchronously achieving the efficacy of improving the yield and the productivity efficiency of the molding machine, but also limiting the volume of the molding machine from being overlong.
