Description

Technical Field

[0001] This utility model relates to a plastic tube shaping mold with a novel positioning lock, belonging to the field of plastic tube shaping mold technology. Background Technology

[0002] The plastic pipe forming mold is formed by bending the pipe into a plastic pipe mold using a fully automatic pipe bending machine or by cutting the pipe section to the required angle using wire cutting technology and welding it into a plastic pipe mold section. After the angle grinder performs grooving, a plastic pipe mold cover plate and a plastic pipe mold bottom cavity are formed. In order to avoid the quality problems caused by the plastic pipe bulging outward when steam passes through it, a cover plate is used to press the plastic pipe inside the plastic pipe mold bottom cavity. However, the existing technology has the following drawbacks: First, the plastic pipe mold cover plate is prone to lateral misalignment: When the plastic pipe passes through steam, it will slightly expand in diameter. The plastic pipe mold cover plate is prone to lateral misalignment, which will cause damage to the surface of the plastic pipe, affecting the surface quality of the formed plastic pipe. Moreover, the maintenance process requires a lot of time to adjust the position of the cover plate, resulting in a significant reduction in production efficiency. Second, the longitudinal clamping force of the plastic pipe mold cover plate is not fixed: After the plastic pipe mold is opened, the installation position of the positioning lock hook needs to be manually adjusted. When the positioning lock hook positions the plastic pipe mold cover plate, the plastic pipe mold cover plate will be subjected to uneven force, resulting in uneven roundness of the plastic pipe in the bottom cavity, affecting the shaping quality of the plastic pipe. Third, the position of the plastic pipe mold positioning lock hook is not fixed: After the plastic pipe mold is opened, each time the positioning lock hook is installed, the plastic pipe needs to be placed into the bottom cavity of the plastic pipe mold, and the plastic pipe mold cover plate is pressed on it to install the hinge. The tightness of the plastic pipe mold cover plate is adjusted by manually adjusting the position of the cover plate positioning lock hook. The manual adjustment is difficult to control to the optimal state, which wastes time and reduces production efficiency. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a plastic tube shaping mold with a novel positioning lock to solve the problems mentioned in the background art.

[0004] This utility model discloses a plastic tube shaping mold with a novel positioning lock, the shaping mold comprising: The mold body includes a plastic tube mold bottom cavity 1 and a plastic tube mold cover plate 2 hinged to one side above the plastic tube mold bottom cavity 1; The positioning locking block includes a lower positioning locking block 3 and an upper positioning locking block 4. The lower positioning locking block 3 is welded to the outer wall of the bottom cavity 1 of the plastic tube mold, and the upper positioning locking block 4 is welded to the outer wall of the cover plate 2 of the plastic tube mold. The lower positioning locking block 3 and the upper positioning locking block 4 are correspondingly snapped together. Positioning hook 5 is installed on the outer wall of the mold body, located on the right side of the positioning lock block.

[0005] Furthermore, the lower positioning lock block 3 is provided with a first mounting hole 301 on its lower side.

[0006] Furthermore, the lower side of the positioning hook 5 is provided with a second mounting hole 501 of the same size as the first mounting hole 301.

[0007] Furthermore, the lower positioning locking block 3 is connected to the positioning locking hook 5 via bolts 6 and nuts 7.

[0008] Furthermore, a washer 8 is provided on the bolt 6 between the lower positioning locking block 3 and the positioning locking hook 5.

[0009] The beneficial effects of this utility model are as follows: 1. This utility model has a simple structure and is easy to operate. It realizes the limitation of the lateral displacement of the plastic tube shaping mold cover plate by the angle of the positioning locking block, avoids the lateral displacement and misalignment caused by the single positioning locking hook, and avoids the damage to the surface of the plastic tube, thus improving the product quality.

[0010] 2. This utility model breaks away from the traditional method of using only positioning hooks to fix the plastic tube shaping mold cover plate by combining positioning hooks and positioning blocks. The positioning blocks fix the longitudinal locking force, ensuring the roundness of the plastic tube shaping mold and preventing the plastic tube from deforming due to uneven force, thus improving product quality.

[0011] 3. This utility model achieves a combination of positioning hook and positioning block, breaking the traditional situation where the installation position of positioning hook is not fixed. It solves the problem that it is not easy for employees to control the position and clamping force when installing positioning hook during the process of making molds. The positioning hook and the cover plate positioning lock can be assembled together, which greatly improves the production efficiency of employees. Attached Figure Description
