Description

Technical Field

[0001] The utility model belongs to the technical field of plastic moulds, in particular to a hardware placement fixture for plastic moulds. Background Art

[0002] In plastic molds related to port connections of electronic devices, it is widely used to place hardware in plastic molds for molding together. Whether a clamp is needed depends on the difficulty of the hardware's structure and production efficiency. Hardware with simple structures can be directly hung in the plastic mold for direct production, while complex or smaller hardware needs to be fixed with a clamp.

[0003] A Chinese patent document (application publication number CN219855686U) discloses a hardware placement fixture for plastic molds, which includes a base, the left and right ends of the base are fixedly connected to two fixing mechanisms, the upper end of the base is fixedly connected to a bottom plate, the upper end of the bottom plate is slidably connected to two lower molds, the front and rear ends of the two lower molds are fixedly connected to a connecting buckle, and a clamping groove is opened between the bottom plate and the two lower molds.

[0004] It can be seen that although the patent document cited above sets the two lower molds and the bottom plate in a slidable connection mode, and a clamping groove is opened between the two lower molds and the bottom plate, after the injection molding is completed, the two lower molds can be pulled apart to take out the product between the two lower molds and the hardware inside the clamping groove, so that the removal of the hardware will not be limited by the lower mold. However, due to the heavy weight of the mold, this manual opening and closing of the lower mold is more time-consuming and laborious, and the whole process is more labor-intensive, which can easily cause physical fatigue to the staff after working for a long time.

The outer wall of the sliding rod is equipped with two second connecting plates, and one side of the two second connecting plates is fixedly connected to the other side of the two lower molds respectively.

[0010] As a preferred embodiment, one end of the screw rod is connected to a side bearing of another first fixing plate.

[0011] As a preferred embodiment, the bottom ends of the two lower molds are each provided with a slide bar, and the outer walls of the four slide bars are respectively slidably connected to the top end of the base.

[0012] As a preferred embodiment, a pull block is installed at one end of the mounting rod, and one side of the pull block is fixedly connected to one end of the spring.

[0013] As a preferred embodiment, when the spring is in a normal state, the mounting rod is not in contact with the second fixing block.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The hardware placement fixture for plastic molds benefits from the design of the motor, the screw and the first connecting plate. The motor drives the two first connecting plates to move in opposite directions through the screw, thereby driving the two lower molds to move in opposite directions. In this way, it is convenient to open and close the lower molds to take out the hardware. The whole process is labor-saving, highly automated, and has low work intensity, which avoids physical fatigue of the staff after long hours of work.

[0016] By providing an auxiliary fixing component, when the two lower molds are closed after taking out the materials, the auxiliary fixing component can be used to further increase the tightness of the connection between the two lower molds, so as to avoid the injection liquid from overflowing from between the two lower molds during injection molding.

When the motor 402 works, it drives the two lower molds to move in opposite directions through the screw rod 403, so that it is convenient to open and close the lower mold 2 to take out the hardware. The whole process is easy and labor-saving, with low work intensity, and avoids causing physical fatigue to the staff after long-term work.

[0031] Motor 402 is a conventional instrument, and its working principle, size and model are irrelevant to the function of the present application, so no further description will be given. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0032] The auxiliary fixing assembly 5 provided in this embodiment includes a first fixing block 501, which is installed on one side of one of the lower molds 2. A mounting rod 502 is penetrated through one side of the first fixing block 501, and the mounting rod 502 is slidably connected to the first fixing block 501. A spring 503 is sleeved on one end of the outer wall of the mounting rod 502, and an elastic block 504 is installed on the other end of the outer wall of the mounting rod 502. The outer wall of the elastic block 504 is equipped with a second fixing block 505, and a clamping hole is opened at the top of the second fixing block 505. The elastic block 504 is clamped and connected with the second fixing block 505 through the clamping hole, and one side of the second fixing block 505 is fixedly connected to one side of the other lower mold 2.

[0033] The present embodiment provides that two second fixing plates 405 are installed on the sides of the top of the base 1, and a sliding rod 406 is commonly provided on the opposite side of the two second fixing plates 405. The outer wall of the sliding rod 406 is equipped with two second connecting plates 407.

When the spring 503 is in a normal state, the installation rod 502 is not in contact with the second fixed block 505.

[0036] How it works

[0037] After the hardware is clamped in the clamping groove 3 and the injection molding is completed, the elastic block 504 is pressed downward, and the pull block 506 is driven to move outward under the elastic action of the spring 503. The movement of the pull block 506 drives the installation rod 502 to move outward until it is separated from the second fixed block 505, and then the motor is turned on. The motor 402 drives the screw rod 403 to rotate. The rotation of the screw rod 403 drives the two lower molds 2 to move in opposite directions through the two first connecting plates 404, and then the product between the lower molds 2 and the hardware in the clamping groove 3 are taken out. In this way, it is convenient to open and close the lower mold 2 to take out the hardware. The whole process is easy and labor-saving, with low work intensity, and avoids causing physical fatigue to the staff after long-term work.
