Description

Technical Field

[0001] The present invention relates to the technical field of injection molding processing, and specifically relates to an automated thread mold removing machine integrating unloading and repairing functions. Background Art

[0002] The production of injection molded products generally includes processes such as plastic batching and molding. For injection molded products, especially those with threads, the thread molds connected by threads on the injection molded products need to be removed. Generally, the thread molds are removed by manually unscrewing them. Facing a large number of continuous injection molded products on the injection molded product production line, using the manual unscrewing method is time-consuming, laborious, and has low efficiency.

[0003] Existing thread mold removing devices also have problems such as complex structures, damaged threads of the injection molded products after removal, easy appearance of burrs and flash, etc. Moreover, the injection molded products after all the thread molds are removed still need to go through the next process to remove the burrs and flash on the threads, which is rather troublesome. Summary of the Invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides an automated thread mold removing machine integrating unloading and repairing functions, aiming to achieve the functions of automatically removing the thread mold and removing burrs and flash, so as to improve the efficiency.

[0005] To achieve the above object, the specific solution adopted by the present invention is as follows: An automated thread mold removing machine integrating unloading and repairing functions includes a base, a placement platform provided on the base, and an execution component provided above the placement platform;

[0006] A plurality of first access shafts and second access shafts are vertically arranged in the placement platform and are respectively arranged side by side. Both ends of the first access shaft and the second access shaft penetrate through the placement platform. The first access shaft is used for inserting the thread mold, and a tool is inserted on the second access shaft. Both the first access shaft and the second access shaft are driven by a motor provided on one side of the placement platform to rotate along their own circumferences;

[0007] The execution component includes a horizontal moving plate and a lifting plate provided below the horizontal moving plate. The horizontal moving plate is slidably arranged on the base through a connecting member provided thereon. The lifting plate is slidably arranged on the horizontal moving plate. A clamping member for clamping the injection molded product is provided on the lifting plate. The first access shaft and the second access shaft are located on the horizontal movement trajectory of the clamping member, so as to clamp the injection molded product on the thread mold inserted in the first access shaft through the clamping member. At the same time, under the rotation of the first access shaft, the thread mold on the injection molded product is removed. Then, driven by the horizontal moving plate, the clamping member clamping the injection molded product moves above the second access shaft, and driven by the lifting plate, the clamping member moves the injection molded product downward to the tool, so as to remove the burrs and flash on the injection molded product through the tool.

[0008] As a further optimization of the above technical solution: An electric lead screw is horizontally arranged on the base. One end of the connecting member is connected to the horizontal moving plate, and the other end is connected to the nut on the electric lead screw, so as to drive the horizontal moving plate to move along the length direction of the electric lead screw through the electric lead screw.

[0009] As a further optimization of the above technical solution: All the first access shafts and the second access shafts are on the same straight line, and the arrangement direction of the first access shaft and the second access shaft is the same as the length direction of the electric lead screw.

[0010] As a further optimization of the above technical solution: The lifting plate is connected to the piston rod of the first cylinder arranged on the horizontal moving plate, so as to drive the lifting plate to reciprocate along the direction towards the horizontal moving plate through the first cylinder.

[0011] As a further optimization of the above technical solution: The clamping member is composed of two clamping plates, and the opposite sides of the two clamping plates are respectively connected to the piston rods of the second cylinders arranged on the lifting plate.

[0012] As a further optimization of the above technical solution: The transmission mode between the motor and the first access shaft and the second access shaft is belt drive.

[0013] As a further optimization of the above technical solution: The placement platform is erected on the base through a support plate, and a support structure is provided at the position corresponding to the first access shaft between the placement platform and the base. The support structure is used to support the thread die with the bottom passing through the first access shaft.

[0014] As a further optimization of the above technical solution: The support structure includes a frame arranged on the base. A plurality of sliding rods are vertically arranged on the frame. The positions of the sliding rods correspond to the first access shafts one by one. The top ends of the sliding rods extend out of the frame and limit blocks are arranged on the sliding rods. Springs are sleeved on the sliding rods at the positions between the limit blocks and the base. Grooves for the sliding rods to enter are opened on the base, so that when the thread die axially moves in the first access shaft, the sliding rods support the thread die and prevent it from falling out of the first access shaft.

[0015] As a further optimization of the above technical solution: A travel switch is arranged on the side wall of the lifting plate, and the contact of the travel switch faces the placement platform. Thus, when the lifting plate moves downward, the travel switch is triggered, and then the motor is started to drive the first access shaft to rotate.

[0016] As a further optimization of the above technical solution: The bottom of the horizontal moving plate is connected with legs, and the bottom ends of the legs pass through the lifting plate and are provided with rollers that rollingly cooperate with the placement platform.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1) In the present invention, an injection-molded product is inserted into the first access shaft. Then, the execution component clamps and fixes the injection-molded product within the first access shaft. The first access shaft rotates, and the threaded mold connected to the bottom of the injection-molded product rotates and is removed. Subsequently, the execution component moves the injection-molded product to the tool on the second access shaft to complete the work of trimming burrs, thus realizing automatic removal and repair and improving work efficiency.

[0019] 2) A support structure is provided below the first access shaft of the present invention. When removing the threaded mold, the threaded mold makes rotational and axial movements. The support structure supports the threaded mold so that it does not fall out of the first access shaft. And when the execution component moves the injection-molded product towards the second access shaft, under the action of the spring of the support structure, the threaded mold pops out of the first access shaft to complete automatic detachment.

Detailed Embodiment

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] Please refer to Figure 1 An automated threaded mold removal machine integrating unloading and repair functions, comprising a base 1, a placement platform 2 provided on the base 1, and an execution assembly 4 provided above the placement platform 2;

[0029] As Figure 2 shown, the placement platform 2 is used to place the injection molded product with the threaded mold to be removed and set the tool 203, and provides the power for the tool 203 and the injection molded product to perform rotational movement. A plurality of first access shafts 201 and second access shafts 202 are vertically provided in the placement platform 2 and are respectively arranged side by side. The top and bottom ends of the first access shaft 201 and the second access shaft 202 penetrate through the placement platform 2. The first access shaft 201 is located in the area near the edge of the placement platform 2, and the second access shaft 202 is located in the middle area of the placement platform 2. Moreover, the first access shaft 201 and the second access shaft 202 are on the same straight line. The top ends of the first access shaft 201 and the second access shaft 202 both have interfaces. The first access shaft 201 is for inserting the threaded mold, that is, the injection molded product with the threaded mold to be removed, with the upper part being the injection molded product and the lower part being the threaded mold, and inserting the lower threaded mold into the first access shaft 201. A tool 203 is inserted on the second access shaft 202. A motor 204 is provided on one side of the placement platform 2. As Figure 4 shown, the output shaft of the motor 204 drives an endless belt, and a plurality of belt pulleys are adapted to the endless belt. The belt pulleys are provided on the first access shaft 201 and the second access shaft 202. Thus, by means of belt drive, after the motor 204 is started, each belt pulley rotates, and then the first access shaft 201 and the second access shaft 202 rotate, and it is ensured that the rotation directions of each first access shaft 201 and the second access shaft 202 are the same.

[0030] As Figure 1 and 3As shown, the execution component 4 is used to clamp and fix or drive the injection molded product to move. The execution component 4 includes a horizontal moving plate 402 and a lifting plate 401 arranged below the horizontal moving plate 402. A connecting piece 404 is provided on the horizontal moving plate 402. The connecting piece 404 is of a T-shaped structure. One side of the connecting piece 404 is fixedly connected to the horizontal moving plate 402, and the other side is connected to the nut of the electric lead screw 101 horizontally arranged on the base 1, so as to drive the horizontal moving plate 402 to move along the length direction of the electric lead screw 101 through the electric lead screw 101; a guide pin is vertically arranged on the lower surface of the horizontal moving plate 402, the lifting plate 401 is sleeved on the guide pin, and the lifting plate 401 is connected to the piston rod of the first cylinder 403 fixed on the horizontal moving plate 402. The piston rod of the first cylinder 403 is perpendicular to the horizontal moving plate 402, so that the lifting plate 401 can move up and down under the drive of the first cylinder 403. A second cylinder 405 is provided on the lifting plate 401. The piston rod of the second cylinder 405 is parallel to the horizontal moving plate 402. There are two second cylinders 405 and they are arranged oppositely. Clamping plates 408 are provided on the piston rods of the two second cylinders 405. The two clamping plates 408 form a clamping member for clamping and fixing the injection molded product. Thus, the clamping plates 408 are driven to move relatively by the second cylinder 405 to clamp or release the injection molded product. The first access shaft 201 and the second access shaft 202 are on the horizontal movement track of the clamping member, and the arrangement direction of the first access shaft 201 and the second access shaft 202 is the same as the length direction of the electric lead screw 101.

[0031] The placing platform 2 is erected by a support plate 102 provided on the base 1. A support structure 3 is provided between the placing platform 2 and the base 1 corresponding to the position of the first access shaft 201. When removing the thread mold of the injection product, the thread mold needs to perform axial movement and rotational movement. That is, the support structure 3 is used to prevent the thread mold from falling out of the first access shaft 201, and at the same time, it should not affect the axial movement of the thread mold. The support structure 3 includes a frame body 301 provided on the base 1. The frame body 301 is an L-shaped mechanism and is composed of a vertical plate and a horizontal plate. The vertical plate is fixedly connected to the base 1, and the horizontal plate is fixed at the top of the vertical plate. A plurality of sliding rods 304 are inserted into the horizontal plate. The sliding rods 304 correspond to the first access shaft 201 one by one. The top ends of the sliding rods 304 penetrate through the horizontal plate, and a limiting block 303 is provided on the rod body of the sliding rod 304 below the horizontal plate. A spring 302 is sleeved on the sliding rod 304 between the limiting block 303 and the base 1. A groove for the sliding rod 304 to enter is opened on the base 1. When the thread mold performs axial movement, the bottom end of the thread mold abuts against the sliding rod 304 and pushes the sliding rod 304 to move downward. That is, while the sliding rod 304 supports the thread mold to prevent the thread mold from falling out of the first access shaft 201, it does not affect the removal of the thread mold. After the upper operation platform leaves the position of the first access shaft 201, under the action of the spring 302, the thread mold is jacked out of the first access shaft 201, facilitating the recycling of the thread mold.

[0032] A travel switch 409 is also fixed on the lifting plate 401. The contact of the travel switch 409 faces the placing platform 2. Thus, when the lifting plate 401 moves downward to the position of clamping the injection product, the travel switch 409 is triggered, and then the motor 204 is triggered to start. Legs 406 are provided at the bottom of the horizontal moving plate 402. The bottom ends of the legs 406 pass through the lifting plate 401 and are provided with rollers 407 that are in rolling cooperation with the placing platform 2.

[0033] The working process of the present invention is as follows: First, insert the injection-molded product into the first access shaft 201. Start the first cylinder 403. After the piston rod of the first cylinder 403 pushes the lifting plate 401 downward to an appropriate position, the second cylinder 405 is started. The second cylinder 405 drives the clamping member to clamp and fix the injection-molded product. At the same time, the travel switch 409 on the lifting plate 401 is triggered, and then the motor 204 is started. The motor 204 drives the first access shaft 201 and the second access shaft 202 to rotate. At this time, the thread mold at the lower part of the injection-molded product performs both rotational motion and axial motion. During the axial motion of the thread mold, the bottom end gradually pushes the slide rod 304 downward, and then the thread mold is removed. The lifting plate 401 moves upward under the drive of the first cylinder 403. At this time, the injection-molded product is on the clamping member, and the thread mold is in the first access shaft 201. Then, the horizontal moving plate 402 moves in the direction of the second access shaft 202 under the drive of the electric lead screw 101, thereby driving the lifting plate 401 to move above the second access shaft 202. At this time, the thread mold in the first access shaft 201 pops out under the action of the spring 302. Then, the lifting plate 401 moves downward under the action of the first cylinder 403, and the cutter 203 trims the burrs of the injection-molded product. Then, the lifting plate 401 moves upward, and the horizontal moving plate 402 drives the lifting plate 401 to move forward again to an appropriate position. The clamping member releases the injection-molded product. A collection box can be arranged in front of the placement platform 2 to collect the injection-molded products from which the thread molds have been removed. Then, the lifting plate 401 and the horizontal moving plate 402 return, and the previous motion can be repeated in a cycle. It should be noted that when the lifting plate 401 clamps the injection-molded product above the cutter 203, a new injection-molded product with a thread mold to be removed can be inserted into the first access shaft 201 again.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
