Specific embodiment

The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model Limitation.

It please refers to shown in prior art Fig. 1 to Fig. 3, die casting of lower cover of automobile thermostat with special-shaped structure, structure is main It include: lower cover 10 and die casting plug 40.The lower cover 10 is completed from upper and lower and side edge direction core pulling respectively；Its With first inner chamber 20 and second inner chamber 30.The inner width of the first inner chamber 20 is greater than the width of its first outlet 21.This The inner width of two inner cavities 30 is greater than the width of its second outlet 31.The lower cover components of this polymorphic structure are traditional pumpings What core mode cannot be completed.

The structure forms first inner chamber 20 and the part of 30 shape of second inner chamber is split into another die casting, i.e. Fig. 3 institute It is body formed can to complete lower cover from tri- direction core pullings of A, B, C respectively for " plug " shown, and lower cover as shown in Figure 2.In addition, Can the inner hole of outer circle and die casting lower cover 10 to die casting plug 40 finish, then by plug 40 from the A in Fig. 4 Side pressure enters in the hole of lower cover 10, size, form and the completely the same product of Fig. 1 is formed, to complete casting die new process Overall production process.

The molding process of die casting of lower cover of automobile thermostat with special-shaped structure can be expressed as follows: firstly, passing through die casting Machine, compression mod are manually packed into mold insert, motor-driven molding；Furthermore hand stock, motor-driven back under pressure, pressure-cure, motor-driven die sinking, Eject casting；Finally, artificial pickup, takes out mold insert, and clear up die casting, obtains die casting finished product.

Meeting die-casting process condition is this mold design difficult point, and the structure design of interior mold insert and interior mold insert are determined in mold , interior mold insert installation and taking-up in production process manufacture mold insert in interchangeability and are used to produce.

Compared to the sand core cast of prior art production, the utility model die casting of lower cover of automobile thermostat with special-shaped structure The advantages of can be expressed as follows: 1. using plurality of geometries combination constitute in mold insert, solution bursts small interior big core pulling problem.2. wanting Point: stable, accurate location structure, reasonable service life.3. consumptive material compares: 750 grams of substance of original process sand core cast, existing 395 grams of die casting substance, reduce aluminium alloy materials 47%.4. production efficiency compares: original process sand core cast production time per piece 10 Minute/part, 1 minute/part of die casting production time per piece improve production efficiency 900%.5. many merits: intensity raising 25~ 30%, dimensional accuracy is high, and finish is good, processing capacity very little.

As shown in Fig. 4 to Fig. 5, in order to further decrease manufacture difficulty, the automobile polymorphic structure thermostat of the utility model Lower cover die casting, lower cover are to be divided into the first component 50 and second component 60, and one end of the first component 50 is perpendicular to second The outer surface on the surface of part 60, the first component 50 is equipped with the first convex block 51 and the second convex block 53, the outer surface of second component 60 Equipped with mounting groove 61 and third convex block 62, the first convex block 51 is placed in mounting groove 61, and third convex block 62 and the second convex block 53 are mutually tight It pastes and is connected between third convex block 62 and the second convex block 53 by clamping piece 70.This structure is to be divided into first by lower cover Component 50 and second component 60, and cooperate the first convex block 51 be placed in mounting groove 61 and third convex block 62 and the second convex block 53 it Between be connected by clamping piece 70, can Fast Installation at lower cover, and further decrease producting process difficulty.

Wherein the first component 50 and second component 60 carry out die-casting process by die casting machine respectively, solve 50 He of the first component Using in press casting procedure between second component 60, there is die casting discontinuity, it is ensured that the first component 50 and second component 60 are made The quality made.In addition, the first component 50 and second component 60 can separate, convenient for the convenience safeguarded in the future；In addition, avoiding die casting Plug 40 is stuck in lower cover.

This practical described first component 50 is equipped with the first recess 52, and the upper surface of die casting plug is placed in the first recess 52 Place.The first component 50 is equipped with the first inclined-plane 53, and the upper surface of die casting plug is placed at the first inclined-plane 53, is further convenient for Fixed die casting plug 40 acts on, and is equipped with cavity in the die casting plug 40, further decreases the weight of die casting plug 40 This etc. drops with implementation.

60 joint of the first component 50 and second component described in the utility model is equipped with sealing ring 80.Or specifically into one Step, the third convex block 62 and 53 connection of the second convex block are equipped with sealing ring 80, play implementation sealing function.

Upper is only the preferred embodiment of the utility model, is not intended to limit the utility model, all practical new at this Made any modification, equivalent replacement or improvement etc., should be included in the protection of the utility model within the spirit and principle of type Within the scope of.
