Description

Technical Field

[0001] The present invention relates to the technical field of injection molding machines, and specifically to a support mechanism applicable to injection molding machines. Background Art

[0002] Plastics are mainly composed of carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements. The finished products are solids, and they are in a molten state during the manufacturing process. Therefore, they can be heated by a machine to melt, pressured to flow, and cooled to solidify, thus forming various shapes. This huge and diverse material group is called plastics. With the rapid development of the plastics industry and the continuous improvement of plastic properties, plastic parts have been more widely used, and plastic parts are replacing traditional metal parts in different fields.

[0003] Based on the above, the inventor found that the existing support mechanism applicable to injection molding machines mainly has the following deficiencies. For example, the support mechanism of the injection molding machine is the main framework of the whole machine, which can install the lifting column on it to drive the mold to open and close. When replacing the mold, since the lower mold needs to be installed directly below the upper mold and the mass of the mold is relatively large, when the staff moves the mold, it is blocked by the support, making it inconvenient to directly move the mold. Therefore, it is necessary to place the mold at the side of the support and then slowly move the mold in for installation, which is inconvenient for operation. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] Embodiment 1: Please refer to Figures 1 - 6 , the specific embodiments of the present invention are as follows:

[0027] Its structure includes a bracket 1, a main body 2, a support plate 3, and a lifting column 4. The main body 2 is provided at the bottom end inside the bracket 1. The support plate 3 is horizontally installed at the upper end inside the bracket 1. The lifting column 4 is connected to the bottom of the support plate 3. The main body 2 includes a bottom plate 21, a limit groove 22, and a support device 23. The bottom plate 21 is arranged at the bottom end inside the bracket 1. There are four limit grooves 22, which are arranged around the top of the bottom plate 21. The support device 23 is installed above the bottom plate 21 and is engaged with the limit groove 22.

[0028] The support device 23 includes a transverse movement plate 231, a moving device 232, an installation groove 233, and a support block 234. The transverse movement plate 231 is arranged above the bottom plate 21. There are four moving devices 232, which are installed inside the transverse movement plate 231. The installation groove 233 is arranged at the top of the transverse movement plate 231. The support block 234 is installed in the installation groove 233. The moving device 232 is engaged with the limit groove 22, which is beneficial to drive the transverse movement plate 231 to move towards the side end of the bracket 1 through the moving device 232, facilitating the staff to place the mold on the upper end of the support block 234 for installation.

[0029] The moving device 232 includes a movable groove a1, a clamping block a2, a positioning block a3, a swinging rod a4, a cutting groove a5, a sliding device a6, a return spring a7, and a friction block a8. The movable groove a1 is arranged inside the transverse movement plate 231. The clamping block a2 is installed at the upper end inside the movable groove a1. The positioning block a3 is arranged on the left end face of the movable groove a1. The swinging rod a4 is engaged with the positioning block a3. The cutting groove a5 penetrates through the end face of the swinging rod a4. The sliding device a6 is connected to the cutting groove a5 and the clamping block a2. The return spring a7 is installed inside the clamping block a2. The friction block a8 is arranged at the left bottom end of the movable groove a1. The included angle formed between the clamping block a2 and the horizontal plane is 30 degrees. The sliding device a6 is movably engaged with the cutting groove a5 and the clamping block a2. The sliding device a6 is movably matched with the return spring a7. The sliding device a6 is movably matched with the friction block a8, which is beneficial to swing the swinging rod a4, so that the sliding device a6 can squeeze the return spring a7 to move downward under the drive of the swinging rod a4, enabling the sliding device a6 to support the transverse movement plate 231 to move towards the side end of the bracket 1, facilitating the staff to install the mold in the support block 234.

[0030] The sliding device a6 includes a connecting rod a61, a side slider a62, a roller a63, and a contact layer a64. At the top of the connecting rod a61, there is a side slider a62. The side slider a62 is inclined and arranged inside the engaging block a2. The roller a63 is engaged at the bottom of the connecting rod a61. The contact layer a64 is nested on the outer end face of the roller a63. The end face of the side slider a62 is inclined, and the inclination angle is 30 degrees, which is beneficial for the side slider a62 to move in the engaging block a2.

[0031] The contact layer a64 includes a contact body b1, rubber blocks b2, and empty grooves b3. The contact body b1 is nested on the outer end face of the roller a63. There are ten rubber blocks b2, which are arranged around the outer end face of the contact body b1. The empty grooves b3 are arranged inside the rubber blocks b2. The outer end face of the rubber block b2 is triangular, and the bottom end face of the empty groove b3 is zigzag, which is beneficial for the rubber block b2 to contact the end face of the bottom plate 21 and deform into the empty groove b3.

[0032] Based on the above embodiments, the specific working principle is as follows: When the staff is handling the mold, blocked by the bracket, it is inconvenient to directly handle the mold. The moving device 232 can be used to drive the transverse moving plate 231 to move towards the side end of the bracket 1, which is convenient for the staff to place the mold on the upper end of the supporting block 234 for installation. Then, the moving device 232 drives the transverse moving plate 231 to displace into the limiting groove 22, so that the positions of the lower mold and the upper mold can be aligned, avoiding interference from the bracket 1 during installation by the staff. Then, by swinging the swing rod a4, the sliding device a6 can be driven by the swing rod a4 to squeeze the return spring a7 and move downward, enabling the sliding device a6 to support the transverse moving plate 231 to move towards the side end of the bracket 1, which is convenient for the staff to install the mold in the supporting block 234. Then, the transverse moving plate 231 is moved directly below the upper mold, which is convenient for installing the mold. Then, the return spring a7 resets and drives the swing rod a4 to move to the left, enabling the sliding device a6 to contact the end face of the friction block a8, thereby fixing the sliding device a6 and improving the stability during mold injection. Then, by using the movement of the side slider a62 in the engaging block a2, the swing of the swing rod a4 can also drive the sliding device a6 to move and be fixed accordingly. Finally, by using the contact between the rubber block b2 and the end face of the bottom plate 21 and deforming into the empty groove b3, the zigzag end face of the empty groove b3 can support the rubber block b2, thereby improving the stability of the roller a63 and preventing the roller a63 from shifting.

[0033] Embodiment 2: Please refer to Figures 7 - 8 , the specific embodiments of the present invention are as follows:

[0034] The support block 234 includes a support body c1, an introduction groove c2, a guide block c3, an embedding groove c4, and a positioning groove c5. The support body c1 is flange-connected to the upper end face of the transverse movement plate 231. The introduction groove c2 is provided on the top end face of the support body c1. There are four guide blocks c3, which are arranged around the end face of the introduction groove c2. The embedding groove c4 is provided at the middle position of the introduction groove c2. The positioning groove c5 is located exactly in the middle of the embedding groove c4. The end face of the guide block c3 is inclined, and the inclination angle is 30 degrees, which is beneficial to placing the mold on the end face of the support body c1 and then pushing it towards the position of the introduction groove c2.

[0035] The guide block c3 includes a guide body c31, a roller c32, a clamping shaft c33, and a buffer layer c34. The guide body c31 is provided on the end face of the introduction groove c2. The two ends of the roller c32 are provided with clamping shafts c33, and the clamping shafts c33 are clamped inside the guide body c31. The buffer layer c34 is attached to the upper end face of the buffer layer c34. One-fourth of the roller c32 protrudes from the top end face of the guide body c31, which is beneficial to the mold contacting the roller c32 when sliding on the end face of the guide body c31, reducing the friction between the mold and the guide body c31.

[0036] Based on the above embodiments, the specific working principle is as follows: Place the mold on the end face of the support body c1 and then push it towards the position of the introduction groove c2, so that the bottom end face of the mold can move towards the embedding groove c4 through the guidance of the inclined end face of the guide block c3. Then rotate the mold so that the mold is embedded with the positioning groove c5, and the mold can be accurately installed in the support block 234, thus facilitating the installation by the staff. Then, when the mold slides on the end face of the guide body c31, it contacts the roller c32, reducing the friction between the mold and the guide body c31, so that the mold can be smoothly guided into the embedding groove c4, facilitating the installation of the mold by the staff.

[0037] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described.
