Detailed Description

The utility model is described in detail below with reference to the figures and the specific embodiments.

Referring to fig. 1, the present invention provides a high-efficiency and fast plastic part hot bending machine, which includes: the machine table 1, set up in locating piece 2 on the machine table 1, set up in mould hot pressing mechanism 3 at 2 rear ends of locating piece, and set up in heating mechanism 4 of mould hot pressing mechanism 3 side. And a plurality of fixing holes are formed in the positioning block 2 at intervals. During operation, a plastic product to be processed is inserted into the fixing hole on the positioning block 2, and the position to be processed of the plastic product is embedded into the die hot-pressing mechanism 3. Then the heating mechanism 4 heats the die hot-pressing mechanism 3 to raise the temperature, so that the plastic product is bent and deformed along with a cavity in the die hot-pressing mechanism 3 after being heated. After the completion, the mold hot-pressing mechanism 3 is opened, the plastic product is taken out, and the hot-bending process of the plastic product is completed. When the plastic product is subjected to hot bending processing, the plastic product is limited and supported through the fixing hole in the positioning block 2, and the influence on the quality and the effect of a finished product due to deviation in the hot pressing process of the plastic product is avoided, so that the reject ratio of the finished product is reduced, and the requirement of large-scale production activity is met.

The machine table 1 is provided with a fixed seat 21 corresponding to the positioning block 2, and the positioning block 2 is embedded into the fixed seat 21. When a product needs to be replaced, the positioning block 2 can be taken out of the fixing seat 21, and the corresponding fixing seat 21 and the die hot-pressing mechanism 3 are replaced, so that the hot-bending fixing requirements of plastic products of different specifications and models are met, and the universality of the hot-bending machine is improved.

The positioning block 2 is provided with a plurality of handles 22. The handle 22 is provided on the positioning block, so that the operator can conveniently grasp the positioning block 2 when replacing the positioning block.

Referring to fig. 2, the mold hot-pressing mechanism 3 includes: the device comprises a vertical support 31 arranged on the machine table 1, a plurality of first cylinders 32 arranged on the vertical support 31, an upper die 33 connected with the output ends of the first cylinders 32, and a lower die 34 arranged on the machine table 1. The lower mold 34 is correspondingly disposed below the upper mold 33. The first cylinder 32 drives the upper die 33 to reciprocate up and down. The upper die 33 and the lower die 34 are provided with a plurality of die cavities, and the die cavities are arranged at positions corresponding to the fixing holes. During operation, after the plastic product is arranged in the fixing hole on the positioning block 2, the position to be processed of the plastic product is embedded into the die cavity of the lower die 34. The first cylinder 32 then drives the upper mold 33 to move downward, so that the upper mold 33 covers the lower mold 34, and the plastic product is bent and deformed along with the mold cavity in the mold cavity when the heating mechanism 4 heats up. When the mould is opened, the first air cylinder 32 is reset, the upper mould 33 is driven to move upwards, so that the upper mould 33 is separated from the lower mould 34, and an operator can take away the plastic product which is subjected to the hot bending process conveniently.
