[0002] In the production process of traditional injection molding machines, the movable platen is not equipped with a corresponding emergency brake function. When the fast oil cylinder is damaged or broken, the movable platen cannot stop moving in time. Due to inertia, it will continue to move in the original working direction without a protection mechanism to stop or slow down in time. In this case, the movable platen may fall off the track, causing serious damage to the entire equipment system, resulting in serious consequences such as equipment damage, production interruption, and even personal injury. Utility Model Content

[0005] Preferably, the stop block is provided with a long strip-shaped through hole along the length direction of the mold clamping unit bed, and the fixing bolt passes through the long strip-shaped through hole.

[0006] Preferably, a plurality of groups of stop blocks are provided on the bed of the mold clamping unit.

[0007] Preferably, the fixing bolts and the elongated through holes on each group of the stop blocks are provided in plural and corresponding manner.

[0008] Preferably, the number of gaskets on the upper and lower surfaces of the stop block in the same group is respectively one, and a plurality of fixing bolts are simultaneously passed through the gasket located on the upper surface of the stop block and the gasket located on the lower surface of the stop block.

[0009] Preferably, a static platen, a movable platen, and a fast oil cylinder are provided on the bed of the mold clamping unit, and the two stop blocks are both located in the extension direction of the moving path of the movable platen.

[0010] In summary, the utility model includes the following beneficial technical effects:

[0011] In the event that the fast oil cylinder is damaged or broken, a moving platen stop protection device can be added to effectively stop the movement of the moving platen, avoid damage to the equipment caused by derailment of the moving platen, and ensure safety.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The embodiment of the utility model discloses a movable platen stop protection device, which is installed on a mold clamping unit bed 1. A static platen 2 is provided at one end of the mold clamping unit bed 1, and fast oil cylinders 4 are provided at both ends of the static platen 2. The fast oil cylinders 4 are from the end where the static platen 2 is located toward the other end of the mold clamping unit bed 1, and the movable platen 3 is provided between the fast oil cylinders 4 and can move along the direction of the fast oil cylinders 4. Among them, the static platen 2 is a fixed platen; the movable platen 3 is an opening and closing movable platen to form the product; the fast oil cylinders 4 drive the opening and closing movement of the movable platen 3.

[0018] The utility model includes a stop block 5 correspondingly arranged in the extension direction of each fast oil cylinder 4, a gasket 6 respectively arranged on the upper and lower surfaces of the stop block 5, and a fixing screw 7 vertically penetrating the gasket 6 and the stop block 5 and connecting the mold clamping unit bed 1. Among them, the stop block 5 is provided with a long strip through hole, the long strip through hole is arranged along the extension direction of the fast oil cylinder 4, and the fixing bolt penetrates the long strip through hole; the stop block 5 is made of rigid material.

[0019] When the fast oil cylinder 4 is damaged or broken, the moving plate 3 will collide with the stop block 5, thereby preventing the moving plate 3 from moving further, thus preventing damage to the machine and affecting the customer's daily production schedule. The long through hole design on the stop block 5 ensures a safe buffer distance. After the collision, the buffer distance reduces the impact force of the moving plate 3 on the stop block 5, thus preventing the loosening and damage of the structural parts.

[0020] In addition, there are six long strip-shaped through holes and fixing bolts on each stop block 5 and they are arranged correspondingly. In addition to penetrating the gasket 6 located on the upper surface of the stop block 5, the six fixing bolts also penetrate the gasket 6 located on the lower surface of the stop block 5.

[0021] The utility model has the following effects:

[0022] 1. Adding a stop device can prevent the moving plate 3 from continuing to move when the fast oil cylinder 4 is damaged or broken, thereby avoiding damage to the machine and the entire equipment system.

[0023] 2. Increase the safety of equipment and avoid machine damage affecting normal daily production arrangements.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
