and a transferring step: the clamping device 110 moves to a position deviated from the injection mold 120, the injection mold 120 is switched to a mold clamping state, and the injection mold 120 performs injection again.
It will be appreciated that an automotive part may include a plurality of parts, and each part may have a different shape and material according to the function and stress of the part, and each part may be separately molded during injection molding, and then each part may be assembled to form the automotive part. Prior to injection molding, the injection information is acquired to confirm the material, the amount of injection, the injection temperature, and the injection time required for the auto parts molded on the injection mold 120, thereby ensuring the quality of the injection molded auto parts.
In the injection molding step, the injection mold 120 is set in a mold-closed state, an injection molding material is injected into the injection mold 120 and fully fills the cavity of the injection mold 120, the first workpiece 121 and the second workpiece 122 are injection molded, the first workpiece 121 and the second workpiece 122 are suitable for being connected to form an assembly, the first workpiece 121 can be a clamping pin, the second workpiece 122 is a clamping seat, and the second workpiece 122 is suitable for being sleeved on the first workpiece 121 to form the assembly. After injection molding, the first workpiece 121 and the second workpiece 122 are cooled and shaped after a first preset time. The injection mold 120 is switched to the mold-open state so as to take out the first work 121 and the second work 122. In some embodiments, the injection mold 120 includes a front mold and a rear mold that are in contact with each other in a closed state and are separated in an open state to facilitate ejection of the first or second workpiece 121, 122.
The clamping device 110 is used to grasp the first workpiece 121 and the second workpiece 122 and to join the first workpiece 121 and the second workpiece 122 to form an assembly. Specifically, the clamping device 110 is moved to a position corresponding to the injection mold 120, and the injection mold 120 ejects the first workpiece 121 and the second workpiece 122, wherein the clamping device 110 is adapted to clamp the first workpiece 121, and the second workpiece 122 is adapted to be sleeved on the first workpiece 121, so that the first workpiece 121 and the second workpiece 122 are assembled to form an assembly.
In the ejection process, when the injection mold 120 sequentially ejects the first workpiece 121 and the second workpiece 122, the first workpiece 121 is ejected onto the clamping device 110, and after the clamping device 110 clamps the first workpiece 121, the injection mold 120 ejects the second workpiece 122 so that the second workpiece 122 is sleeved on the first workpiece 121 to form an assembly, and then the first workpiece 121 and the second workpiece 122 of the assembly are both injection molded in the same batch.
When the injection mold 120 ejects the first workpiece 121 and the second workpiece 122 at the same time, after the first batch of the first workpiece 121 and the second workpiece 122 are injection molded, the clamping device 110 moves to the injection mold 120 to clamp, and the first workpiece 121 is not clamped on the clamping device 110. Thus, in producing the first plurality of second workpieces 122, the injection mold 120 ejects the first plurality of second workpieces 122, and the first plurality of second workpieces 122 are ejected from the injection mold 120.
For example, in the first lot of first workpieces a and the first lot of second workpieces B, the clamping device 110 clamps the first lot of first workpieces a, and the first lot of second workpieces B are ejected from the injection mold 120 and fall off; in the second batch of first workpieces a 'and the second batch of second workpieces B', the clamping device 110 clamps the second batch of first workpieces a ', and the second batch of second workpieces B' are ejected and sleeved on the first batch of first workpieces a to form an assembly, that is, the first workpieces 121 are assembled with the second workpieces 122 of the next batch to form the assembly.
After the injection molding step, the first workpiece 121 and the second workpiece 122 are removed from the injection mold 120 through the assembling step, and the first workpiece 121 and the second workpiece 122 are assembled to form an assembly, so that a continuous process is formed, the process of transferring the first workpiece 121 and the second workpiece 122 between various devices is saved, the production steps are simplified, and the efficiency is improved. In addition, only the clamping device 110 and the injection mold 120 are matched with each other to finish demolding and assembling of the first workpiece 121 and the second workpiece 122, so that required production equipment is reduced, and production cost is saved.
In the transferring step, the clamping device 110 is moved to a position deviated from the injection mold 120, and the assembly is transferred to a predetermined position for a next process, such as detecting, weighing, packing the assembly, and the injection mold 120 performs a next injection. The clamping device 110 is moved to a position deviated from the injection mold 120, so that the clamping device 110 is prevented from interfering with the movement of the injection mold 120. For example, after the front mold and the rear mold of the injection mold 120 are separated, the first workpiece 121 and the second workpiece 122 are both positioned on the rear mold, the first workpiece 121 and the second workpiece 122 are both ejected from the rear mold toward one side of the front mold, and the clamping device 110 is moved between the front mold and the rear mold to clamp the first workpiece 121 and the second workpiece 122; after the first workpiece 121 and the second workpiece 122 are clamped and the assembly is formed, the clamping device 110 is moved to a position deviated from the injection mold 120, the front mold and the rear mold are relatively moved to be in contact with each other, and the injection mold 120 is switched to a mold clamping state to perform injection again to injection mold the first workpiece 121 and the second workpiece 122.
According to the control method of the production equipment for manufacturing the automobile parts, the first workpiece 121 and the second workpiece 122 are removed from the injection mold 120 by arranging the assembly step in the injection molding step, and the first workpiece 121 and the second workpiece 122 are ejected to the clamping device 110, so that the first workpiece 121 and the second workpiece 122 are assembled to form an assembly to form a continuous process, the process of transferring the first workpiece 121 and the second workpiece 122 between the equipment is saved, the production step is simplified, and the efficiency is improved. In addition, only the clamping device 110 and the injection mold 120 are matched with each other to finish demolding and assembling of the first workpiece 121 and the second workpiece 122, so that required production equipment is reduced, and production cost is saved.
According to some embodiments of the present invention, the clamping device 110 is provided with a plurality of clamping modules 112, each clamping module 112 is adapted to clamp the first workpiece 121, and the injection mold 120 ejects the first workpiece to the position of the clamping module 112, so that the clamping module 112 clamps the first workpiece 121. The plurality of clamping modules 112 are uniformly and at intervals along the circumferential direction of the clamping device 110, the clamping device 110 can clamp the plurality of first workpieces 121, and the plurality of first workpieces 121 and the plurality of second workpieces 122 on the clamping device 110 are assembled to form a plurality of assemblies.
The clamping device 110 is rotatable along its own axis at a first station and a second station, such that the plurality of clamping modules 112 sequentially clamp the first workpiece 121 and the second workpiece 122. In the assembling step, when the clamping device 110 rotates to the first station, the clamping module 112 is adapted to clamp the first workpiece 121 being ejected; when the clamping device 110 is rotated to the second station, the second workpiece 122 is ejected and mounted onto the first workpiece 121 to assemble the assembly. For example, the first workpiece 121 is a clamping pin, the second workpiece 122 is a clamping seat, when the clamping device 110 is located at the first station, the injection mold 120 ejects the clamping pin, and the clamping module 112 clamps the clamping pin; the clamping device 110 rotates to the second station, so that the clamping module 112 for clamping the card pin is opposite to the position of the card holder, and the card pin is opposite to the connecting hole on the card holder for inserting the card pin. After the injection mold 120 ejects the clamping seat, the clamping seat is sleeved on the clamping needle, so that the clamping needle and the clamping seat are assembled to form an assembly.
Referring to fig. 2, according to some embodiments of the present invention, the clamping device 110 includes a plurality of layers of clamping units 111 stacked, the plurality of layers of clamping units 111 are cylindrical, four clamping modules 112 are disposed on each layer of clamping units 111, the four clamping modules 112 are uniformly distributed at intervals along the circumferential direction of the clamping units 111, and the clamping device 110 rotates 90 degrees during the process of rotating the clamping unit 111 from the first station to the second station.
As shown in fig. 3, taking a single clamping unit 111 as an example, four clamping modules 112 are uniformly distributed in the circumferential direction of the clamping unit 111, and the clamping modules 112 are a first module C1, a second module C2, a third module C3 and a fourth module C4 in sequence in the counterclockwise direction. When the assembling step is performed, the clamping device 110 is moved to the injection mold 120, the clamping device 110 is at the first station, the position of the clamping module 112 on the clamping unit 111 is shown in fig. 3, at this time, the first module C1 is opposite to the position of the first workpiece 121, and the second module C2 is corresponding to the position of the second workpiece 122. When the injection mold 120 sequentially ejects the first workpiece 121 and the second workpiece 122, the first module C1 clamps the first workpiece 121 after the first workpiece 121 is ejected. After the first module C1 clamps the first workpiece 121, the clamping device 110 rotates to the second station, and the clamping unit 111 rotates 90 degrees in the counterclockwise direction, so that the positions of the first module C1 and the second workpiece 122 are opposite, the injection mold 120 ejects the second workpiece 122, and the second workpiece 122 is sleeved on the first workpiece 121 on the first module C1 to form an assembly.

The injection mold 120 is set in a mold closing state, and based on the obtained glue injection information, glue is injected into the injection mold 120, and the injection mold 120 performs first injection molding to form a first workpiece a and a first workpiece B. And cooling and shaping the first batch of first workpieces A and the first batch of second workpieces B which are formed by injection molding, and switching the injection mold 120 to an open mold state after a first preset time so as to demold the first batch of first workpieces A and the first batch of second workpieces B.
Referring to fig. 5, broken lines and arrows in the drawing indicate the movement directions of the corresponding parts. After the injection mold 120 is switched to the mold opening state, the clamping device 110 is moved to the injection mold 120, at this time, the clamping device 110 is located at the first station, each layer of clamping units 111 on the clamping device 110 corresponds to a pair of first workpieces a and a first batch of second workpieces B, a first module C1 of the plurality of clamping modules 112 on the clamping units 111 is aligned with a position of the first workpieces a, and a second module C2 is aligned with a position of the first workpieces B. The injection mold 120 ejects a first batch of first workpieces A and a first batch of second workpieces B at the same time, and the first module C1 clamps the first batch of first workpieces A; if the first workpiece is clamped on the second module C2, the first batch of second workpieces B are sleeved on the first workpiece to form an assembly, and if the first workpiece is not clamped on the second module C2, the first batch of second workpieces B naturally drop after being ejected from the injection mold 120, and a recovery box can be arranged under the injection mold 120 to recover the dropped first batch of second workpieces B.
