Abstract

This utility model belongs to the field of shaping fixtures, specifically relating to a hot-press shaping fixture, including an upper mold and a lower mold. The upper mold is controlled to move up and down by a hot press machine, while the lower mold consists of a flat plate and several protruding limiting blocks disposed on the plate. The semi-finished product is fixed by the limiting blocks. The upper and lower molds are closed and hot-pressed to flatten the semi-finished product. Several cooling air blowers on the side of the shaping fixture release cold air until the semi-finished product is shaped and remains undeformed. The beneficial effects of this utility model are: improved production efficiency and capacity, guaranteed product yield and stability of deformation, and significantly reduced waste of space and resources.

Description

Hot pressing fixture

technical field

The utility model belongs to the field of plastic shaping fixtures, in particular to a hot-pressing shaping fixture. the

Background technique

The deformation degree of the electronic product is very large and unstable when it is just completed. The technology currently used in the market is that after the product is dispensed and hot-pressed, the deformation degree of the product will rebound after standing for 48H, and the deformation degree will stabilize after standing for 72H. the

The shortcomings of the current technology: low production efficiency and poor timeliness, the yield rate is not easy to control and takes up a lot of space, resulting in serious waste of resources, etc. shelves for static placement). the

Utility model content

The purpose of the utility model is to overcome the above-mentioned problems, and provide a hot-pressing shaping treatment that improves the timeliness and yield of production, effectively controls the deformation of the product and does not rebound after shaping, and reduces unnecessary space and waste of resources. Tool. the

In order to achieve the above purpose, the technical solution adopted by the utility model is: a hot-pressing shaping fixture, including an upper die and a lower die, characterized in that the upper die is controlled by a hot-pressing machine to move up and down, and the lower die is composed of a flat plate and a It is composed of several raised limit blocks on the flat plate. The semi-finished product is fixed by several limit blocks. The upper and lower molds are clamped and hot-pressed to complete the leveling of the semi-finished product. A number of cooling blowing heads installed on the side of the shaping fixture release cold air. Until the semi-finished product is shaped and not deformed. the

In the aforementioned heat-pressing and shaping fixture, the upper mold is a leveling plate, which is connected to the power unit of the hot press, and the leveling plate is arranged horizontally. the

The aforesaid heat-pressing and shaping fixture also includes a base supporting the lower mold and a support seat supporting the upper mold. the

In the aforementioned heat-pressing and shaping jig, the cooling and blowing heads are arranged on both sides of the shaping jig, at least two. the

In the aforementioned heat-pressing setting fixture, the cooling blowing head is connected to the air valve switch, and the opening and closing of the cooling blowing head is controlled by the air valve switch. the

The utility model puts the semi-finished product that has been hot-pressed after dispensing into the imitation hot-pressing fixture, presses the switch of the automatic hot-pressing machine to close the upper and lower molds, and then opens the air valve switch to make the gas blow on the product to accelerate cool down. Process parameters: The processing time of imitation hot-pressing setting fixture operation is defined as 35 seconds. the

The beneficial effects of the utility model are: improving production efficiency and production capacity, ensuring product yield and stability of deformation, and reducing waste of space and resources. the

Fig. 1 is the structural diagram of the present utility model;

Among them, 1 upper mold, 2 lower mold, 3 base, 4 support seat, 5 limit block, 6 cooling blowing head.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described. the

According to Figure 1, the hot-pressing shaping fixture is used to install the products that have been hot-pressed by dispensing glue on the automatic hot-pressing machine. There are manually controlled air valve switches on the left and right sides of the automatic heat press machine. When the product is pressed, the cooling blowing head is opened to accelerate the rapid cooling, shaping and shaping of the product. the

The hot-press setting fixture includes an upper mold 1 and a lower mold 2, and is characterized in that: the upper mold 1 is controlled by a hot-pressing machine to move up and down, and the lower mold 2 consists of a flat plate and several raised limit blocks arranged on the flat plate 5, the semi-finished product is fixed by a number of limit blocks 5, the upper and lower molds are clamped and hot-pressed to complete the leveling of the semi-finished product, and a number of cooling blowing heads 6 provided on the side of the shaping fixture release cold air until the semi-finished product is shaped and does not deform. The upper mold 1 is a leveling platen, which is connected with the power unit of the hot press, and the leveling platen is arranged horizontally. It also includes a base 3 supporting the lower die 2 and a support seat 4 supporting the upper die 1 . The air blowing heads are arranged on both sides of the shaping jig, at least two. The air blowing head is connected with the air valve switch, and the opening and closing of the air blowing head is controlled by the air valve switch. the

The specific operation process is as follows: 1. Put the hot-pressed product into the hot-pressing fixture; 2. Press the switch of the automatic hot press to close the upper and lower molds; 3. Then open the air valve switch to let the gas blow Accelerate cooling on the product, and the cooling processing time is 35 seconds; 4. After the time is up, the pressing machine will automatically open, close the air valve switch, the product is finalized and the end is over. the

The above-mentioned embodiments do not limit the utility model in any form, and all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the utility model. the
