Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically a single-slide vertical injection molding machine with a brake. Background Technology

[0002] A vertical injection molding machine is a mechanical device. It typically consists of an injection system, a mold clamping system, a hydraulic transmission system, an electrical control system, a lubrication system, a heating and cooling system, and a safety monitoring system. The injection system is one of the most important components of the injection molding machine, and generally comes in three main forms: plunger type, screw type, and screw pre-plasticizing plunger injection type. The screw type is the most widely used. Its function is to heat and plasticize a certain amount of plastic within a specified time during one cycle of the injection molding machine, and then inject the molten plastic into the mold cavity through the screw under certain pressure and speed.

[0003] Existing vertical standard injection molding machines have high worktables, making it inconvenient to pick up and place inserts and finished products. The specific structure or method of existing technology is to use a vertical low-position disc injection molding machine, with the mold installed on the disc. Different positions can be switched by rotating the disc. Under the same tonnage, the disc injection molding machine has a large footprint, complex structure, high technical content, high cost, and poor mold compatibility. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a single-slide vertical injection molding machine with a brake to solve the problems mentioned in the background. This utility model has a novel structure. Compared with the footprint of a rotary machine, the single-slide machine with a brake has a smaller machine width, and there is extra space on both sides and under the slide for equipping automated equipment, making it more convenient to pick up parts. Under the premise that the worktable height is almost the same, its structure is simpler. The reciprocating motion of the slide does not require too much equipment control, reducing costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-slide vertical injection molding machine with a brake, comprising an injection molding machine housing, an injection molding device mounted on the top of the injection molding machine housing, and a door rotatably mounted on the outer surface of the injection molding machine housing. Inside the injection molding machine housing, a base plate is fixed opposite to the injection molding device, and a lower template is slidably mounted on the top of the base plate. An upper template is provided on the top of the lower template, and a brake assembly is provided on the top of the upper template. The brake assembly includes connecting seats, connecting seats are fixed at the four corners of the top of the upper template, and a brake device is fixedly mounted between the connecting seats on both sides of the upper template. A delivery platform is fixed on one side of the injection molding machine housing, and a support plate is provided on the delivery platform. The top of the base plate is flush with the top of the support plate.

[0006] Furthermore, the bottom of the injection molding device is provided with an injection head, and a feeding channel is fixed on one side of the top of the injection molding device. The upper template is provided with an injection hole corresponding to the position of the injection head.

[0007] Furthermore, an installation hole is provided on the middle surface of the upper template, and a lifting cylinder is fixedly installed in the installation hole. The injection molding device is installed on the lifting cylinder.

[0008] Furthermore, the brake assembly also includes a second cylinder, which is fixed at the four corners of the bottom of the base plate, and the extended end of the second cylinder is fixed with studs. The upper template and the connecting seat are slidably sleeved on the four studs.

[0009] Furthermore, a telescopic column is fixed to one side of the upper template, and a connecting rod is fixed to the top of the bottom plate at the position corresponding to the telescopic column, with the extended end of the telescopic column fixedly connected to the connecting rod.

[0010] Furthermore, a sliding plate is snapped onto the bottom of the lower template, and the sliding plate is slidably installed on the bottom of the injection molding machine housing. A third cylinder is fixed on the side of the injection molding machine housing away from the delivery stage, and the extended end of the third cylinder is fixedly connected to the sliding plate.

[0011] Furthermore, the injection molding machine housing has limit blocks fixed on both sides of the slide plate, and the slide plate slides along the inside of the limit blocks. The outermost end of the tray is provided with an outer plate, and a foldable buffer layer is fixed on the inner surface of the outer plate. The slide plate and the buffer layer are in pressure contact.

[0012] Furthermore, the top of the delivery table is provided with a support plate, and the bottom of the delivery table is fixed with a first cylinder, the extended end of the first cylinder being fixedly connected to the support plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, when the base plate is located at the bottom of the opening end of the bearing plate, the two sets of telescopic plates are located on both sides of the push plate. During the rotation of the bearing plate, the telescopic plates will move horizontally with the base plate, and the ash residue will fall between the two telescopic plates. When the base plate returns to its original position, the telescopic plates will push the ash residue towards the center. The push plate will be moved by the electric push rod, which can concentrate the ash residue and push it out from the discharge port, making cleaning more convenient.

[0015] 2. This utility model utilizes a brake mechanism and a fast cylinder to achieve a larger mold opening stroke without increasing the mold cylinder stroke, thus adapting to molds of the same size but different heights.

[0016] 3. The connecting seat of this utility model can be locked in different positions of the stud by opening and closing the brake device, and then the upper template can be raised to different heights by opening the second cylinder, so that it can be used for molds of different heights.

[0017] 4. In this utility model, after the upper template is lifted, the third cylinder pushes the slide plate along the limiting frame to the top of the tray on the delivery platform. During this process, the slide plate first squeezes the buffer layer, causing it to fold, which can serve as a buffer and deceleration to prevent the injection molded object from falling due to inertia. Then the slide plate resets and the first cylinder drives the tray to move upward, making it easier to remove the object from the tray and also facilitating loading.

[0018] 5. Compared with the prior art and the footprint of the disc machine, the single-slide brake machine has a smaller platform width, and there is extra space on both sides and under the slide for equipping automated equipment, making it more convenient to pick up parts; with the same worktable height, its structure is simpler; the reciprocating motion of the slide does not require too much equipment control, reducing costs.

An injection molding device 3 is installed on the top of the injection molding machine housing 1, and a door 11 is rotatably installed on the outer surface of the injection molding machine housing 1. A base plate 5 is fixed inside the injection molding machine housing 1, directly opposite the injection molding device 3. A lower template 52 is slidably installed on the top of the base plate 5. An upper template 51 is provided on the top of the lower template 52, and a brake assembly 4 is provided on the top of the upper template 51. The brake assembly 4 includes connecting seats 45. Connecting seats 45 are fixed at the four corners of the top of the upper template 51. A brake device 46 is fixedly installed between the connecting seats 45 on both sides of the upper template 51.

The top of the base plate 5 is flush with the top of the support plate 22. In traditional machines, the mold opening and closing is achieved through the linkage of the mold cylinder and the fast cylinder. The stroke of both determines the mold opening stroke, and the stroke of the mold cylinder and the fast cylinder are approximately equal. This means that if the mold opening stroke is increased, the stroke of both cylinders must also be increased. This device utilizes a brake mechanism and a fast cylinder to achieve a larger mold opening stroke without increasing the stroke of the mold cylinder, thus adapting to molds of the same size but different heights. First, the brake device 46 is released, the second cylinder 41 raises the upper template 51, and the slide cylinder controls the slide plate 53 to slide out. The user places the mold and insert, the slide plate 53 slides back, the second cylinder 41 closes the mold and presses the upper template 51 onto the mold, the brake device 46 locks, and the lifting cylinder 32 is used to apply high pressure, the product is formed, and the first step is repeated.

[0026] In this embodiment, the injection molding device 3 is provided with an injection head 33 at its bottom, and a feeding channel 31 is fixed on one side of the top of the injection molding device 3. The upper template 51 is provided with an injection hole 48 corresponding to the position of the injection head 33. An installation hole 47 is provided on the middle surface of the upper template 51.

The installation hole 47 on the top of the upper template 51 is used to install the injection molding device 3. The feeding channel 31, injection hole 48 and lifting cylinder 32 of the injection molding device 3 are all based on the same principle as existing vertical injection molding machines.

[0027] In this embodiment, the brake assembly 4 further includes a second cylinder 41. The second cylinder 41 is fixed at the four corners of the bottom of the base plate 5, and the extended end of the second cylinder 41 is fixed with a stud 44. The upper template 51 and the connecting seat 45 are slidably sleeved on the four studs 44. A telescopic column 42 is fixed on one side of the upper template 51. A connecting rod 43 is fixed on the top of the base plate 5 at the position corresponding to the telescopic column 42, and the extended end of the telescopic column 42 is fixedly connected to the connecting rod 43. The connecting seat 45 can be locked and installed at different positions of the studs 44 by the opening and closing state of the brake device 46. Then, the upper template 51 is raised to different heights by opening the second cylinder 41, so as to be suitable for use with molds of different heights.

[0028] In this embodiment, a sliding plate 53 is snapped onto the bottom of the lower template 52. The sliding plate 53 is slidably mounted on the bottom of the injection molding machine housing 1. A third cylinder 55 is fixed on the side of the injection molding machine housing 1 away from the delivery stage 2, and the extended end of the third cylinder 55 is fixedly connected to the sliding plate 53. Limiting blocks 54 are fixed on both sides of the injection molding machine housing 1 on the sliding plate 53, and the sliding plate 53 slides along the inside of the limiting blocks 54. An outer plate 23 is provided at the outermost end of the support plate 22, and a folded buffer layer 24 is fixed on the inner surface of the outer plate 23. The sliding plate 53 is in pressure contact with the buffer layer 24. The top of the delivery platform 2 is provided with a tray 22, and the bottom of the delivery platform 2 is fixed with a first cylinder 21. The extended end of the first cylinder 21 is fixedly connected to the tray 22. After the upper template 51 is lifted, the third cylinder 55 pushes the slide plate 53 to slide along the limiting frame to the top of the tray 22 of the delivery platform 2. During this process, the slide plate 53 first squeezes the buffer layer 24 to fold it, which can serve the purpose of buffering and deceleration, preventing the injection molded object from falling due to inertia. Then the slide plate 53 resets, and the first cylinder 21 drives the tray 22 to move upward, which makes it easier to take out the object on the tray 22 and also facilitates loading.

[0029] When using the device, firstly, the brake device 46 is released, the second cylinder 41 raises the upper template 51, and the slide cylinder controls the slide plate 53 to slide out. The user places the mold and inserts, the slide plate 53 slides back, the second cylinder 41 closes the mold and presses the upper template 51 onto the mold, the brake device 46 locks, and the lifting cylinder 32 is used to apply high pressure, and the product is formed. Repeat the first step. After the upper template 51 is lifted, the third cylinder 55 pushes the slide plate 53 to slide along the limit frame to the top of the tray 22 of the delivery stage 2. During this process, the slide plate 53 first squeezes the buffer layer 24 to fold it, which can serve the purpose of buffering and deceleration, preventing the injection molded object from falling due to inertia. Then the slide plate 53 resets, and the first cylinder 21 drives the tray 22 to move upward, making it easier to remove the object on the tray 22 and also facilitating loading.
