Detailed Description
The following detailed description of the embodiments of the present invention is provided in connection with the accompanying drawings for illustrating the embodiments of the present invention so that the technical solutions of the present invention can be understood and appreciated more easily.
According to the utility model, a designer creatively provides a combined mechanism by expanding the design of a mechanical arm for taking a piece through discharging aiming at the complexity of the operation that a release agent needs to be manually sprayed on an injection molding cavity after the traditional one-mold multi-cavity product is discharged and the low efficiency of manual glue shearing operation after the product is discharged, so that a multifunctional composite transfer carrier is enlarged, the function of the mechanical arm is expanded, the utilization rate of the mechanical arm is improved, and the problems of discharging and synchronous release agent spraying of an injection mold are solved.
In combination with the special specification and performance requirements of a certain small part, the combined mechanism is formed by assembling a multi-axis mechanical arm (generally within five axes) based on an injection molding machine. As shown in fig. 1, fig. 2 and fig. 3, the general structural features include a frame base plate 2 driven by a mechanical arm 1 to move in space and a glue shearing port unit 3 arranged outside the side of the injection molding machine, wherein the frame base plate 2 is distributed and connected with a pneumatic clamp group 4, a pneumatic ejector rod 5 and a carrier 21 along the length direction, and the carrier serving as a function expansion base is connected with a release agent tank 6. The mold release can is also assembled in a direction suitable for spraying toward the mold cavity. In order to comply with the convenience of discharging and taking the injection molding finished products, the frame base plate 2 is vertically moved in the inner cavity of the injection molding machine, clamps the injection molding finished products, sprays a release agent towards the cavity of the mold core, overturns outside the injection molding machine to be horizontally positioned and aligned, the glue shearing opening unit is moved and positioned, the glue shearing opening unit 3 is provided with pneumatic scissors 31 corresponding to the quantity of the injection molding finished products and with upward cutting edges, and the mechanical arm and all pneumatic components are jointly controlled through a main controller bus of the injection molding machine.
The essential features of the combination mechanism and its connection relationship and action state can be understood based on the above summary: as a frame substrate, a pneumatic clamp group is connected, and the connected mechanical arms are used for moving inside and outside the injection molding machine to take and discharge materials, which is the conventional arrangement for most plastic product manufacturers. However, in view of the movable range of the mechanical arm in the mold opening range of the injection molding machine, the travel range can be more finely divided and the application can be developed. When the finished product is taken out of the cavity and is taken out of the injection molding machine upwards, the mechanical arm can decelerate and slowly move in a proper height position, so that a feasible scheme of spraying the release agent can be realized by utilizing the displacement stroke set by the length of the cavity of the corresponding mold core. Therefore, the length of the frame substrate is increased and the carrier is arranged, so that the release agent can be conveniently assembled on the frame substrate. Of course, besides firmly positioning the release agent tank, the release agent tank needs to be considered to solve the problem of triggering spraying as required, so the pneumatic ejector rod is arranged, and the pressing action of fingers can be simulated through controlled ejection, so that the release agent can be uniformly ejected to the cavity of the mold core. The capacity of the release agent tank can be measured by testing the mold production to correspond to the replacement frequency of the processing period, so that the release agent tank can be replaced manually at regular intervals according to the production and processing records of the injection molding machine. Therefore, the above-described carrier is preferably improved in terms of the ease of replacement in structure, in addition to the soundness of loading.
In view of spraying the release agent, it is generally preferable that the injection-molded product finally stays in the cavity of the side core where the mold is located. Thus, the spray head of the conventional mold release can is unidirectional and is disposed opposite to the side cavity 711. For the mold 72 and the mold core 721 on the other side of the opened mold, if the mold release agent needs to be sprayed for the mold release treatment, a mold release agent tank with two opposite spray heads in two directions can be selected, or the back side of a single spray head of the mold release agent tank is directly drilled, so that the mold release agent can be sprayed towards two opposite mold cavities of the opened mold synchronously. No matter adopt unilateral or both sides to spray, utilize this combined mechanism's technological improvement, can avoid the manual work frequently to open the injection molding machine side door and get the piece and spray the operation, also reduced the damage rate that causes that the side door frequently opened and close when having reduced manual work intensity.
From the further detailed features, the injection molding product in the preferred embodiment is a mold with eight cavities, and the pneumatic clamp sets are attached to the frame base plate corresponding to the number and position distribution of the injection molding product and controlled to move synchronously, each pneumatic clamp clamps the main body part of the injection molding product except the glue opening, and part of the pneumatic clamps are controlled to clamp the glue column connected with the injection molding product. In the figure, the pneumatic clamps are arranged in a 4 × 2 array, a pair of clamping jaws of each pneumatic clamp respectively clamp two sides of an injection molding finished product, and each clamping jaw of a group of adjacent pneumatic clamps a glue column, so that after a glue shearing opening is finished, the pneumatic clamps can be controlled to sequentially release the finished product and the glue column to different transfer material boxes.
Particularly, a limit push rod (not shown) can be optionally arranged at the jaw of the pneumatic clamp, and pushing is triggered after the pneumatic clamp finishes taking a piece, so that the depth of each pneumatic clamp for clamping an injection molding finished product is consistent, and the conditions of missed shearing and adhesion of the finished product to a glue column in the subsequent glue shearing operation are avoided.
Because the release agent tank 6 is a purchased finished product, the spray head 61 is usually small and the surface is a special-shaped surface suitable for being pressed by fingers, and the force transmission stability of the pneumatic ejector rod to the spray head needs to be improved in order to ensure the smooth development of the release agent spraying operation. Therefore, the push plate 51 is provided at the end of the pneumatic ejector 5, and the push plate 51 is in clearance fit with the nozzle 61 of the mold release agent tank in the reset state, and presses the mold release agent sprayed from the trigger nozzle in the push-up state.
In addition, as a main component of the discharging operation of the combined mechanism, in order to cooperate with the discharging operation of the mechanical arm, the height adaptability is required to be provided, and the requirement of saving the operation space is met. Therefore, it can be seen that the glue shearing opening unit 3 is provided with a floor base 32, a height-adjustable upright 33 and a platform 34 assembled from bottom to top, the pneumatic scissors 31 are arranged on the platform 34 corresponding to the glue opening position distribution of the injection molding finished product, and all the pneumatic scissors 31 are controlled to synchronously close the cutting edge and shear the glue opening and release the cutting edge. Usually, the floor base 32 can be fixed on the ground, and the mobility is relatively poor, and in order to realize the high-precision positioning fit with the mechanical arm, the above-mentioned microscope carrier 34 is further provided with a slide rail slide block 35 to enable the slide rail slide block to become an adjustable slide seat.
According to the number and the position of the glue openings of the injection molding finished product, the number of the pneumatic scissors can be halved, and the alignment is adjusted through the controlled small-amplitude movement of the mechanical arm after the primary glue opening shearing is finished, so that the secondary glue opening shearing is carried out. Of course, enough pneumatic scissors can be arranged and the glue cutting port can be cut at one time to complete the operation.
In summary, as can be seen from the detailed description of the combined mechanism of the present invention in conjunction with the illustrated embodiments, the combined mechanism has outstanding substantive features and significant improvements in the application of the combined mechanism to an injection molding machine: by increasing the frame substrate, integrating the pneumatic ejector rod and the carrier and assembling the release agent tank, on the basis of the carrier function of mechanical arm part taking and discharging, the novel function of automatically spraying the release agent in a required range is expanded; meanwhile, the mechanical arm and the glue shearing opening unit are aligned at high precision, so that quick glue removing opening processing can be realized, the efficiency is improved, and the labor is saved.
