Description

Technical Field

[0001] The utility model relates to the field of composite material products, in particular to a thermoforming mould for products made of composite materials. Background Art

[0002] Composite materials are new materials that are made by optimizing and combining material components of different properties using advanced material preparation technology. The matrix materials of composite materials are divided into two categories: metal and non-metal. Commonly used metal matrices are aluminum, magnesium, copper, titanium and their alloys. Non-metal matrices mainly include synthetic resins, ceramics, carbon, etc. Reinforcement materials mainly include glass fiber, carbon fiber, boron fiber, aramid fiber, silicon carbide fiber, asbestos fiber, whisker, and metal.

[0003] Thermoforming is used in some composite materials made of glass fiber, carbon fiber, boron fiber, and aramid fiber, such as ice hockey sticks, long sticks, and grass sticks. The forming method is to put the product into the mold cavity, then put it into a hot press furnace to heat and form it, and then put it into a cold press furnace to cool it down and take out the product.

[0004] Because the product is relatively long or relatively large, in order to increase production capacity, a thermoforming mold with multiple cavities will be made. However, in this case, the mold is large and heavy, which is inconvenient when transferring from the hot pressing furnace to the cold pressing furnace, and when placing the product in the mold cavity, the upper mold is placed on the hot pressing furnace, and the lower mold is taken out of the cold pressing furnace. If the mold is directly fixed on the thermoforming furnace, it is not easy to operate the upper and lower products. If the molding furnace needs to be able to perform hot pressing and cold pressing at the same time, heat energy will be wasted when hot pressing is converted to cold pressing, increasing costs. If the thermoforming mold is made smaller and thinner to reduce weight, it will affect the molding quality of the product and the life of the mold. Utility Model Content

[0005] The purpose of the utility model is to provide a thermoforming mold for a product made of composite materials to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A hot forming mold for a product made of composite materials, comprising a lower mold and an upper mold, the lower mold comprising a lower mold base and a lower mold core, the lower mold base is a square material, has a plurality of guiding outer guide pillars on the left and right sides and a plurality of pressing grooves for fixing on the shaping furnace pressure plate, a lower mold core groove is provided in the middle for slidingly matching with the lower mold core, a plurality of inner guide pillars are provided at the front and rear side corners of the lower mold core, a plurality of product cavities are provided in the middle, and a handle is provided at the front end, the upper mold comprises an upper mold base and an upper mold core, the upper mold base is a square material, has a plurality of outer guide sleeves on the left and right sides for slidingly matching with the outer guide pillars and a plurality of pressing grooves for fixing on the shaping furnace pressure plate, an upper mold core groove is provided in the middle for slidingly matching with the upper mold core, a plurality of inner guide sleeves are provided at the front and rear side corners of the upper mold core for slidingly matching with the inner guide pillars of the lower mold core, and a plurality of product cavities are provided in the middle.

[0008] As a further solution of the utility model: the lower die core groove of the lower die seat has two side surfaces of the front entrance set to be conical, larger in the front and smaller in the back, and multiple sets of side pulleys are set on the left and right sides. The side pulleys are installed parallel to each other up and down, and the outermost surfaces of the side pulleys are flush with the left and right sides of the lower die core groove.

[0009] As a further solution of the utility model: two positioning columns are provided on the left and right sides of the bottom front portion of the lower die core groove of the lower die seat.

[0010] As a further solution of the utility model: the two side surfaces of the rear end of the lower mold core are set to be conical, with the front larger and the rear smaller, and multiple groups of inner pulleys are set on the left and right sides. The inner pulleys are installed parallel to the left and right, and the outermost surfaces of the inner pulleys are flush with the bottom surfaces of the lower mold base and the lower mold core groove.

[0011] As a further solution of the utility model: the upper die core groove of the upper die seat has left and right side surfaces set as inclined surfaces inclined inwardly, with the lower part being larger and the upper part being smaller.

[0012] As a further solution of the utility model: the left and right side surfaces of the upper die core are set to be conical, with the upper part being smaller and the lower part being larger, and slidingly matched with the left and right side surfaces of the upper die core groove of the upper die seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: by dividing the upper and lower molds into a mold base and a mold core, the mold base is fixed on the molding furnace table, and the mold is placed on the molding furnace table and lowered on the molding furnace table during molding, and when the mold is rotated, only the upper and lower mold cores need to be moved, thereby reducing the weight of the mold, so that under the same operable weight, the mold can produce more products with one mold, greatly improving the product production capacity and reducing the cost of a single product; the lower mold base and the lower mold core of the lower mold are provided with a plurality of pulleys, so that the lower mold core can slide in the up and down directions and left and right directions when entering the lower mold base to reduce friction, thereby reducing the work intensity of workers during operation; at the same time, it is realized that the lower mold base and the upper mold base can be shared, so in order to increase the life of the mold, only the upper and lower mold cores need to be replaced and better materials are used to greatly reduce the mold manufacturing cost, and when a new mold for a new or similar product is opened, only the upper and lower mold cores need to be made, so the mold manufacturing cost is greatly reduced, thereby reducing the cost of new product development.
