This application is through setting up first peripheral surface region 1113 and the second peripheral surface region 1213 that have gapped between first die holder 11 and second die holder 12, under the condition of not adjusting first die holder 11 and second die holder 12 locking force, through reducing the regional area of compound die, increase the pressure of first compound die surface region 1112 and second compound die surface region 1212, need not to use the sealing washer, the glue leakage appears in avoiding the production process, and therefore, the production cost is reduced, and the quality of products is improved.
It is understood that the pressure is a physical quantity for representing the pressure generating effect, and is determined by the pressure and the force-bearing area, and for the two solid bodies (corresponding to the first die holder 11 and the second die holder 12 in the embodiment) which are abutted, the greater the pressure is, the greater the stress at the contact surface is, i.e. the contact between the contact surfaces of the two solid bodies is closer. Specifically, pressure is pressure/atress area, that is, increase pressure can be realized through increase pressure, reduce the atress area two kinds of modes, wherein, in actual production, first die holder 11 and second die holder 12 can be connected through the fastener, the fastener for example can be the screw, it needs to explain, the locking force of screw has certain upper limit, also the pressure has the upper limit, this moment, can realize increase pressure through reducing the compound die area between first die holder 11 and the second die holder 12, make the laminating of compound die surface inseparabler, thereby the well raw materials in the mould cavity of having avoided production process spills, and the production cost is reduced, and the quality of product is improved.
It should be noted that, in the mold provided in this embodiment, a pultrusion production mode is applied, as shown in fig. 2 to fig. 4, the first fitting portion 1111 and the second fitting portion 1211 cooperate to form a cavity, i.e., a space for producing a product, raw materials of the product, such as glass fibers, resin, etc., and the glass fibers and the resin pass through the cavity and are formed in a first direction (mentioned later, refer to the Y direction shown in fig. 5) or a reverse direction thereof by an external pulling device (not shown). In one embodiment, as shown in fig. 2 to 5, the first mating portion 1111 of the first mold base 11 includes a first through groove disposed on the first surface 111, the first through groove penetrates the first mold base 11 along a first direction (Y direction shown in fig. 5), the first mold clamping surface region 1112 is located on two sides of the first through groove and extends along the first direction, and the first peripheral surface region 1113 is located on a side of the first mold clamping surface region 1112 facing away from the first through groove.
With reference to fig. 3 to 5, the first through groove disposed on the first surface 111 penetrates through the first die holder 11 along a first direction, which is a pultrusion production direction.
Referring to fig. 3 and 4, based on the fact that when the first die surface region 1112 of the first die holder 11 and the second die surface region 1212 of the second die holder 12 contact each other, a gap exists between the first peripheral surface region 1113 of the first die holder 11 and the second peripheral surface region 1213 of the second die holder 12, that is, when the first die surface region 1112 and the second die surface region 1212 contact each other to generate pressure, no pressure exists between the first peripheral surface region 1113 and the second peripheral surface region 1213, so that the acting area of the fastener locking force is only the contact area of the first die surface region 1112 and the second die surface region 1212 on both sides of the die cavity, and the increase of the pressure by reducing the die closing area is realized. The first die face areas 1112 are arranged on two sides of the first through groove, namely the first die face areas 1112 are arranged on two sides of the cavity, so that no gap is formed in the inner surface of the cavity, and no glue leakage in the production and processing process is ensured. By setting the first peripheral surface area 1113 to be farther from the first through groove than the first mold clamping surface area 1112, a gap existing between the first peripheral surface area 1113 and the second peripheral surface area 1213 does not affect the structure of the mold cavity, and the sealing effect of the inner contour of the mold cavity is improved.
As shown in fig. 1 and fig. 2, the second matching portion 1211 of the second die holder 12 includes a second through groove disposed on the second surface, the second through groove can match with the first through groove of the first die holder 11 to form a die cavity, the second through groove penetrates through the second die holder 12 along the first direction, the second die surface area 1212 is located on two sides of the second through groove and extends along the first direction, and the second peripheral surface area 1213 is located on a side of the second die surface area 1212 facing away from the second through groove. It will be appreciated that the second die shoe 12 is of the same design as the first die shoe 11, and in one example, the first die shoe 11 can be an upper die and the second die shoe 12 can be a lower die. The above scheme of the second die holder 12 also realizes that the sealing effect of the inner contour of the die cavity is improved on the basis of not influencing the structure of the die cavity, and the structural design of the second die holder 12 side is not repeated here.

Referring to fig. 3 and 4, the first mold clamping surface area 1112 is flush with the first peripheral surface area 1113, so that no additional milling step is required in the production and processing process of the first mold base 11, and only the second peripheral surface area 1213 is arranged away from the first mold base 11, so that only the second peripheral surface area 1213 of the second mold base 12 needs to be milled, and thus the mold clamping areas of the first mold base 11 and the second mold base 12 can be reduced, and the mold manufacturing process is simplified.
In some possible embodiments, referring to fig. 2, 4 and 5, the junction of the second peripheral surface region 1213 to the left of the cavity (with respect to the orientation shown in fig. 2) and the second land region 1212 is provided with a notch 1215, referring to fig. 4, the notch 1215 being spaced further away from the first die holder 11 in the vertical direction (with respect to the Z-direction shown in fig. 2) than the remainder of the second peripheral surface region 1213, the notch 1215 providing a reduction in the area of the second peripheral surface region 1213. It will be appreciated that the second peripheral surface area 1213 is closer to the first die holder 11, and when there is a machining error in the second peripheral surface area 1213, such as a tilt, there may be a possibility that the second peripheral surface area 1213 abuts against a partial structure of the first peripheral surface area 1113 of the first die holder 11, which may affect the assembling effect of the pultrusion die 1. Therefore, by providing the notch 1215 at the intersection of the second peripheral surface area 1213 and the second land area 1212, the processing area of the second peripheral surface area 1213 is reduced, and for example, when the second peripheral surface area 1213 is processed to have a tilt, the second peripheral surface area 1213 has a shorter extension in the vertical direction (Z direction shown in fig. 2), the processing accuracy of the second peripheral surface area 1213 is reduced, and the processing and manufacturing speed of the mold is increased. Meanwhile, the notch 1215 is also used for storing glue which accidentally overflows from the cavity, so that the overflowing glue is prevented from contacting with the fastener, and the fastener is prevented from being taken out.
It will be appreciated that it is within the scope of the present application to position the second land area 1212 flush with the second peripheral area 1213 and thus to position the first peripheral area 1113 away from the second die holder 12.
